GMA 1 AND 3 ndash TRANSMISSIVITY ASSESSMENT AND RECOVERY RECOMMENDATIONS

1 INTRODUCTION

Arcadis US Inc (Arcadis) has prepared this memorandum on behalf of General Electric Company (GE) at the request of the US Environmental Protection Agency (EPA) to present additional data related to both Light Non-Aqueous Phase Liquid (LNAPL) and Dense Non-Aqueous Phase Liquid (DNAPL) recoverability within portions of GErsquos Pittsfield MA site (Figure 1) In the September 30 2016 proposal to EPA entitled ldquoGE-PittsfieldHousatonic River Site (the ldquoSiterdquo) Evaluation of NAPL Recovery Systems ndash Proposed Activities Groundwater Management Areas 1 and 3rdquo GE presented an evaluation approach involving NAPL transmissivity testing including collecting evaluating and reporting additional transmissivity data to evaluate the effectiveness of automated or manual NAPL recovery for these specified areas This memorandum has been prepared to present the results of the NAPL recovery data collected between January 18 2017 and April 20 2017 and provide recommendations for program modifications

11 Background

Since the onset of NAPL recovery at the Site over 35 years ago GE has continuously monitored assessed upgraded expanded and optimized its NAPL recovery efforts Over this time there has been success in 1) removing NAPL from the Site (to varying degrees based on the recovery system) 2) reducing the overall extent and quantity of mobile NAPL that remains within the Site and 3) maintaining compliance with the applicable Performance Standards established in the October 2000 Consent Decree (CD) For certain recovery systems the NAPL recovery rates have diminished over time to the point where limited NAPL recovery is currently being realized This evaluation was performed in accordance with Technical Attachment H of Appendix E to the CD to assess recovery systems at the Site and propose enhancements or modifications as necessary to meet the long-term goal of maximizing NAPL recovery and eliminating mobile NAPL These NAPL transmissivity results are used to evaluate whether NAPL recovery via hydraulic operations remains a feasible and practical alternative for NAPL mass reduction A NAPL transmissivity of 08 square feet per day (ft2day) is used as the criterion for practical NAPL recoverability (ITRC 2009 MassDEP 2016) Below this value hydraulic recovery will not lead to remedial benefit and is not likely to substantially reduce the overall NAPL mass in the subsurface NAPL transmissivity data was collected at the Site beginning in January 2017 and included the completion of five LNAPL baildown tests six DNAPL baildown tests and three LNAPL manual skimming tests

2 METHODOLOGY

This NAPL recoverability assessment is based on NAPL transmissivity measurements Several methods were applied to estimate LNAPL transmissivity including

LNAPL baildown tests

DNAPL baildown tests

LNAPL manual skimming tests

The following sections describe the specific methodology for each of the lines of evidence used in this NAPL recoverability assessment The methodology for LNAPL transmissivity data collection and analysis

are consistent with the ASTM International (ASTM) Standard Guide for Estimation of LNAPL Transmissivity E2856-13 (ASTM 2013)

While no industry-wide standards or test methods currently exist for DNAPL baildown testing the same principles of LNAPL mobility and recoverability are appropriate to evaluate DNAPL mobility (Nelson and Smith 2016 Nelson 2017) Testing was subject to the same pre-test conditions (eg stability of NAPL thickness and no influence from an active recovery system) and testing methods (eg baildown testing) as those conducted for LNAPL assessment Also the active system operations were suspended prior to the test

3 NAPL FIELD TRANSMISSIVITY

The recoverability of NAPL is influenced by many factors including NAPL saturation in the impacted soil soil permeability and physical properties of the NAPL Transmissivity represents the volumetric rate of NAPL flow through a unit width of porous media per unit time under a unit hydraulic gradient A direct mathematical relationship exists between NAPL transmissivity and the rate of NAPL flow into a well therefore it is an ideal parameter for assessing NAPL recoverability NAPL transmissivity calculations inherently account for the combined effects of aquifer matrix permeability NAPL physical properties and the relative proportion of pore space occupied by NAPL within a specified vertical interval of aquifer material Five NAPL samples from wells representative of site conditions (51-08 51-19 106 N2SC-13I and N2SC-01I) were collected and submitted to PTS Laboratories Inc in Santa Fe Springs California for viscosity density and specific gravity analysis Results of the analysis are provided in Appendix A

31 NAPL Baildown Tests

A NAPL baildown test is initiated by quickly removing accumulated LNAPL from a well The rate of NAPL flow into the well is a function of soil and NAPL properties as well as the magnitude of the initial hydraulic gradient toward the well developed during NAPL removal The baildown test response is influenced by the prevalent fluid levels at the time of testing Baildown tests were performed in areas GMA1 (East Street Area 1 and Newell Street Area II) and GMA3 at the Site to describe the range of NAPL transmissivities under different fluid level conditions In general a minimum stable NAPL thickness of about 05 ft is necessary to perform a baildown test

Baildown tests are analyzed in the American Petroleum Institute (API) LNAPL Transmissivity Workbook API Workbook [API 2012]) and a modified API Workbook for DNAPL (Nelson and Smith 2016 Nelson 2017) using modified versions of the Bouwer and Rice (BampR) (1976) and Cooper and Jacob (CampJ) (1946)Jacob and Lohman (1952) slug test method Each of the available solutions involves different assumptions regarding the response of fluid levels within the well to the removal of NAPL Where possible baildown test data are evaluated using each of the solutions If data are not suitable for analysis using one or more of the methods only results obtained using the applicable analysis methods will be reported

Some baildown tests do not generate data that can be analyzed using the API Workbook This generally occurs when there is limited NAPL thickness at test initiation the NAPL in the well is not in equilibrium with the formation or the NAPL discharge into the well cannot be related to the NAPL drawdown induced during the test In cases where the NAPL discharge trend is difficult to identify transmissivity can be estimated

using the manual skimming evaluation method (Section 32) a constant rate of NAPL discharge to the well derived from test data and an average NAPL drawdown induced during that period of the test

Data analysis options in the API Workbook include a data time cut and drawdown adjustment that can be applied as needed A data time cut is required for nearly every test where early-time hydraulic response data representing filter pack drainage is removed from analysis Initial filter pack drainage does not represent formation drainage and an analysis incorporating these data will lead to erroneous results The drawdown adjustment is only applied if NAPL in the well at the time of test initiation is not in equilibrium with NAPL in the formation resulting in a clear trend of zero NAPL discharge at a non-zero (positive or negative) value for NAPL drawdown The drawdown adjustment is applied to reconcile the calculated drawdown with the observed trend toward zero discharge Further information on the data time cut and drawdown adjustment is provided in the user guide for the API Workbook (API 2012)

32 LNAPL Manual Skimming Tests

LNAPL manual skimming tests involve repeated LNAPL recovery periods and thus may test a larger portion of the LNAPL-impacted formation Transmissivity estimates from manual LNAPL skimming tests are expected to correlate more strongly to results that would be expected for LNAPL recovery system operation

A manual skimming test consists of removing all LNAPL from a well gauging the well as the LNAPL recharges and removing LNAPL again before the NAPL thickness reaches 25 percent of the pre-test LNAPL thickness This process is repeated until the LNAPL removal rate stabilizes In general a minimum stable LNAPL thickness of about 03 ft is necessary to perform a manual skimming test

Analysis of the manual LNAPL skimming test data can be completed using Equation 1 (ASTM 2013)

ln

R w

OI r T Q Equation 1

Qn = measured LNAPL recovery rate cubic feet per day (feet3day)

ROI = radius of influence feet

rw = well radius feet

sn = LNAPL drawdown feet

The radius of influence is difficult to estimate for a manual skimming test however because the term occurs within a logarithmic function in Equation 1 the value is not critical for estimating LNAPL transmissivity For this evaluation the value of the term ldquoln (ROIrw)rdquo was assumed to be 46 per ASTM guidance (ASTM 2013)

33 Field Data Collection and Evaluation

(MCP) That guidance document provides details and discussion related to the use of transmissivity testing as part of an overall demonstration of LNAPL recoverability including the feasibility of continued system operation Per the September 30 2016 proposal to EPA and consistent with state regulatory guidance LNAPL transmissivity testing and DNAPL transmissivity testing was performed at select locations within GMA 1 and GMA 3 The results of the tests are summarized below

331 GMA 1 East Street Area 1

Transmissivity testing was proposed to be completed at wells 105 106 and ESA1S-45 based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet Initial gauging prior to the event was conducted during which only one well 106 had sufficient LNAPL thickness to perform a LNAPL baildown test Wells 105 and ESA1S-45 had measurable LNAPL thicknesses of 021 and 016 feet respectively during the initial gauging event Over the course of approximately 8-weeks LNAPL thicknesses in those wells did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively (Table 1) Given the historical recovery volume (Arcadis 2017a) and small vertical interval of measurable LNAPL in each of these wells continued recovery is unlikely to produce a volume that would beneficially reduce LNAPL mass in the subsurface Field data for the LNAPL baildown test at well 106 is included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown test at 106 are included as Appendix C A summary of results is included on Table 2 and is shown on Figure 2

An LNAPL baildown test was initiated at well 106 in January 2017 Prior to the start of the test fluid level gauging and depth to bottom measurements were collected at which point an obstruction or anomaly was detected at a depth of 966 feet bgs while the well depth is typically measured as approximately 175 feet bgs This anomaly has not been observed previously and the fall 2016 and spring 2017 measurements were able to reach the bottom of the well While initial LNAPL thickness could not be determined because the obstruction was above the NAPL-water interface the depth to the NAPL-air interface (depth to LNAPL) was determined and is assumed to represent equilibrium conditions Fluid level measurements were collected periodically for approximately eight hours at the well LNAPL recharged to about 43 of initial measured thickness by the end of the first test day so periodic gauging for LNAPL thickness over the following eight weeks to evaluate further recharge was conducted While water table fluctuations were observed during this time which are expected LNAPL thickness had not returned to the initial thickness observed as of March 2017 (Table 1) Because of the limited LNAPL recharge the baildown test data were not suitable for evaluation by the standard analytical solutions Instead they were analyzed using Eq 1 and a constant rate of NAPL discharge to the well estimated from test data that likely represents formation drainage and an average NAPL drawdown induced during that period of the test This evaluation indicates a transmissivity of about 001 ft2day well below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016)

332 GMA1 Newell Street Area II

DNAPL recoverability testing was proposed to be completed at wells N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14 based on a review of historical gauging data that indicated measurable DNAPL was present at thicknesses greater than 03 feet and at a depth greater than the documented top of sump indicating a hydraulic connection at the time of the test between DNAPL present

in the wells and DNAPL in the surrounding formation Initial gauging was conducted prior to the event during which five of six wells met the thickness and formation connection criteria required to perform a baildown test at the well Baildown tests were completed in January 2017 While on-going gauging was conducted at the area wells for approximately eight weeks following the tests to assess recharge conditions in the well the portion of the tests that were able be evaluated quantitively ranged from approximately four to 28 hours Field data for the DNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for DNAPL baildown tests are included as Appendix C A summary of results is included on Tables 2 and 3 and are shown on Figure 2

Quantitative transmissivity evaluations were completed for four wells N2SC-1I N2SC-1I(R) N2SC-03I(R) and N2SC-14 based on the results of the tests and subsequent gauging At all four wells the tests were analyzed using the API Workbook to determine a transmissivity at the well At three wells a constant NAPL dischargedrawdown analysis was also conducted for a portion of the test where test data likely represents formation drainage

Well N2SC-1I Baildown test results at well N2SC-1I were analyzed using the API Workbook (both BampR and CampJ methods) resulting in estimated transmissivity values above the criterion of recoverability of 08 ft2day The average transmissivity value was 28 ft2day though during the initial purge of DNAPL from the well less than 12 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered Most if not all of the recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-1I(R) which is only several feet away and screened across a similar interval indicated transmissivity values well below the 08 ft2day criteria which is further evidence that calculated recoverability was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-1I(R) Baildown tests at well N2SC-1I(R) were analyzed using both the API Workbook and a constant NAPL dischargedrawdown analysis resulting in estimated transmissivity values below the criterion of recoverability of 08 ft2day The average transmissivity value was 01 ft2day indicating DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I DNAPL was measured in well N2SC-03I at a depth below the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I(R) Baildown test results at well N2SC-03I(R) were analyzed using the API Workbook (both BampR and CampJ methods) and through a constant NAPL dischargedrawdown analysis Transmissivities determined at the well include one value above the 08 ft2day criteria and an average transmissivity of 05 ft2day During the initial purge of DNAPL from the well less

than 25 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered The recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-03I which is only several feet away and screened across a similar interval indicated no recharge from the formation following an initial recovery which is further evidence that calculated recoverability for well N2SC-03I(R) was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-13I Following initial recovery DNAPL was not measured in well N2SC-13I at a depth above the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-14 Gauging data collected from well N2SC-14 following the removal of DNAPL in the well sump indicated measurable DNAPL was present within the well screen interval only once during the initial and subsequent gauging that was conducted periodically for eight weeks following the initiation of the test Where DNAPL recharge is gauged only in the well sump evaluation by the API Workbook is not appropriate and an estimated transmissivity may be derived by utilizing a DNAPL drawdown consistent with the stable thickness in the screened interval and a constant DNAPL discharge determined through a calculation of measured volume of recharge to the well over a given time Late time series data was used to determine DNAPL discharge and DNAPL drawdown this way resulting in a transmissivity of 03 ft2day at the well below the criterion of recoverability of 08 ft2day These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

333 GMA3

Transmissivity testing was proposed to be completed at 13 wells in the GMA3 area based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet However during the pretest gauging only wells 51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17 had sufficient LNAPL thickness to perform either a LNAPL baildown or manual skimming test Over the course of approximately 8-weeks LNAPL thicknesses in the six wells without adequate thickness did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively Field data for the LNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown tests are included as Appendix C and manual skimming test input and output data are included as Appendix D and E respectively A summary of results is included on Tables 2 and 3 and are shown on Figure 3

Quantitative transmissivity evaluation was completed for all wells based on the results of the tests and subsequent gauging At two wells 51-08 and 51-19 the tests were analyzed using the BampR and CampJ

methods in the API Workbook to determine a transmissivity at the well (Table 2) Estimated transmissivity values were below the MassDEP and ITRC criterion of recoverability of 08 ft2day

Manual skimming tests were completed at 59-03R GMA3-12 and GMA-17 and analysis of the data was completed using Equation 1 (ASTM 2013) to estimate a transmissivity at each well The tests were completed in January 2017 and ranged in duration from approximately five to nine hours Periodic purging of LNAPL was performed to maintain an LNAPL thickness of less than 25 percent of the initial gauged thickness and only data that met that criteria were used in the analysis LNAPL transmissivity estimates for all three wells are below the criterion of recoverability of 08 ft2day indicating that continued hydraulic operations would not result in beneficial recovery of LNAPL from the subsurface near the wells

Where baildown test data are not suitable for analysis by the Bower amp Rice and Cooper amp Jacob method the data are analyzed using Eq 1 an estimated constant rate of NAPL discharge to the well from test data that best represents formation drainage and an average NAPL drawdown induced during that period of the test Data collected during tests conducted at wells 51-17 and 51-21 were evaluated in this manner The LNAPL transmissivity estimates 004 ft2day and 0002 ft2day respectively are both below the criterion of recoverability of 08 ft2day

4 CONCLUSIONS

Evaluation of the baildown and manual skimming tests indicate NAPL transmissivities were generally below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016) with two noted exceptions at wells N2SC-1I(R) and N2SC-03I(R) where only a small percentage of the total casing and filter pack volume was able to be removed at the start of the test likely resulting in initial filter pack drainage

Transmissivity calculations from LNAPL baildown tests LNAPL manual skimming tests and DNAPL baildown tests completed in GMA1 and GMA3 generally indicate that NAPL recovery potential at the Site from these specific systems are negligible NAPL transmissivities are below the criterion of recoverability of 08 ft2day (ITRC 2009) with the exception of well N2SC-01I and N2SC-03I(R) in GMA1 The estimated transmissivities at these two wells likely represent filter pack drainage and little if any of the longer-term potential for NAPL recoverability from the formation At N2SC-03I(R) the NAPL transmissivity estimate for only one of the three analysis methods exceeds the MassDEP and ITRC criterion Additionally tests conducted at or near wells with recovery systems in place indicate that further NAPL recovery will not provide a meaningful benefit for the Site A summary of activities conducted and conclusions reached for each area is included below

41 Conclusions for GMA1 East Street Area 1

Of the three wells proposed for testing only one well (106) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

The LNAPL transmissivity estimate for this area is 001 ft2day

42 Conclusions for GMA1 Newell Street Area II

Of the wells proposed for testing all six (N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14) met the criterion to be tested

DNAPL transmissivity estimates for this area ranged from near-zero to 28 ft2day with five of the six estimates below the 08 ft2day MassDEP and ITRC criterion The exceedance to the criteria is likely the result of initial filter pack drainage

43 Conclusions for GMA3

Of the 13 wells proposed for testing in this area only seven wells (51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

LNAPL transmissivity estimates for this area ranged from 0002 ft2day to 04 ft2day

5 RECOMMENDATIONS

Currently in-well NAPL thickness is the criteria by which NAPL recovery at a well is determined to be required In accordance with recently developed standards and guidance endorsed by ITRC ASTM and a number of state agencies including MassDEP it is recommended that NAPL transmissivity data be used to develop a riskbenefit-based approach to NAPL recovery and management at the Site NAPL transmissivity rather than measured NAPL thickness is the most appropriate indicator of the potential for NAPL recovery to provide beneficial reduction in NAPL mass Specific recommendations for changes to the recovery criteria and management program are provided below

51 Recommendations for GMA1 East Street Area 1

Operation of the LNAPL recovery systems in this area should be discontinued because recovery by hydraulic methods in this area is unlikely to beneficially reduce LNAPL in the subsurface

LNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

Fluid level gauging should continue within the well network to monitor LNAPL thickness in wells where it has historically been observed

52 Recommendations for GMA1 Newell Street Area II

Operation of the DNAPL recovery system should be discontinued because DNAPL recovery by hydraulic methods in this area is unlikely to beneficially reduce NAPL in the subsurface

Periodic DNAPL recovery by manual bailing should be continued at wells where transmissivity is found to be greater than 08 ft2day when Site-specific recovery criteria are met

DNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

Note Standard Criteria for manual NAPL removal during monitoring is 025 ft of LNAPL andor 05 ft of DNAPL (Arcadis 2017ab)

53 Recommendations for GMA3

Operation of the LNAPL recovery systems in this area should be discontinued because LNAPL recovery by hydraulic methods in this area is unlikely to beneficially reduce LNAPL in the subsurface

Fluid level gauging should continue within the well network to monitor LNAPL thickness in wells where it has historically been observed

NAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

GMA 1 AND 3 ndash TRANSMISSIVITY ASSESSMENT AND RECOVERY RECOMMENDATIONS

1 INTRODUCTION

Arcadis US Inc (Arcadis) has prepared this memorandum on behalf of General Electric Company (GE) at the request of the US Environmental Protection Agency (EPA) to present additional data related to both Light Non-Aqueous Phase Liquid (LNAPL) and Dense Non-Aqueous Phase Liquid (DNAPL) recoverability within portions of GErsquos Pittsfield MA site (Figure 1) In the September 30 2016 proposal to EPA entitled ldquoGE-PittsfieldHousatonic River Site (the ldquoSiterdquo) Evaluation of NAPL Recovery Systems ndash Proposed Activities Groundwater Management Areas 1 and 3rdquo GE presented an evaluation approach involving NAPL transmissivity testing including collecting evaluating and reporting additional transmissivity data to evaluate the effectiveness of automated or manual NAPL recovery for these specified areas This memorandum has been prepared to present the results of the NAPL recovery data collected between January 18 2017 and April 20 2017 and provide recommendations for program modifications

11 Background

Since the onset of NAPL recovery at the Site over 35 years ago GE has continuously monitored assessed upgraded expanded and optimized its NAPL recovery efforts Over this time there has been success in 1) removing NAPL from the Site (to varying degrees based on the recovery system) 2) reducing the overall extent and quantity of mobile NAPL that remains within the Site and 3) maintaining compliance with the applicable Performance Standards established in the October 2000 Consent Decree (CD) For certain recovery systems the NAPL recovery rates have diminished over time to the point where limited NAPL recovery is currently being realized This evaluation was performed in accordance with Technical Attachment H of Appendix E to the CD to assess recovery systems at the Site and propose enhancements or modifications as necessary to meet the long-term goal of maximizing NAPL recovery and eliminating mobile NAPL These NAPL transmissivity results are used to evaluate whether NAPL recovery via hydraulic operations remains a feasible and practical alternative for NAPL mass reduction A NAPL transmissivity of 08 square feet per day (ft2day) is used as the criterion for practical NAPL recoverability (ITRC 2009 MassDEP 2016) Below this value hydraulic recovery will not lead to remedial benefit and is not likely to substantially reduce the overall NAPL mass in the subsurface NAPL transmissivity data was collected at the Site beginning in January 2017 and included the completion of five LNAPL baildown tests six DNAPL baildown tests and three LNAPL manual skimming tests

2 METHODOLOGY

This NAPL recoverability assessment is based on NAPL transmissivity measurements Several methods were applied to estimate LNAPL transmissivity including

LNAPL baildown tests

DNAPL baildown tests

LNAPL manual skimming tests

The following sections describe the specific methodology for each of the lines of evidence used in this NAPL recoverability assessment The methodology for LNAPL transmissivity data collection and analysis

are consistent with the ASTM International (ASTM) Standard Guide for Estimation of LNAPL Transmissivity E2856-13 (ASTM 2013)

While no industry-wide standards or test methods currently exist for DNAPL baildown testing the same principles of LNAPL mobility and recoverability are appropriate to evaluate DNAPL mobility (Nelson and Smith 2016 Nelson 2017) Testing was subject to the same pre-test conditions (eg stability of NAPL thickness and no influence from an active recovery system) and testing methods (eg baildown testing) as those conducted for LNAPL assessment Also the active system operations were suspended prior to the test

3 NAPL FIELD TRANSMISSIVITY

The recoverability of NAPL is influenced by many factors including NAPL saturation in the impacted soil soil permeability and physical properties of the NAPL Transmissivity represents the volumetric rate of NAPL flow through a unit width of porous media per unit time under a unit hydraulic gradient A direct mathematical relationship exists between NAPL transmissivity and the rate of NAPL flow into a well therefore it is an ideal parameter for assessing NAPL recoverability NAPL transmissivity calculations inherently account for the combined effects of aquifer matrix permeability NAPL physical properties and the relative proportion of pore space occupied by NAPL within a specified vertical interval of aquifer material Five NAPL samples from wells representative of site conditions (51-08 51-19 106 N2SC-13I and N2SC-01I) were collected and submitted to PTS Laboratories Inc in Santa Fe Springs California for viscosity density and specific gravity analysis Results of the analysis are provided in Appendix A

31 NAPL Baildown Tests

A NAPL baildown test is initiated by quickly removing accumulated LNAPL from a well The rate of NAPL flow into the well is a function of soil and NAPL properties as well as the magnitude of the initial hydraulic gradient toward the well developed during NAPL removal The baildown test response is influenced by the prevalent fluid levels at the time of testing Baildown tests were performed in areas GMA1 (East Street Area 1 and Newell Street Area II) and GMA3 at the Site to describe the range of NAPL transmissivities under different fluid level conditions In general a minimum stable NAPL thickness of about 05 ft is necessary to perform a baildown test

Baildown tests are analyzed in the American Petroleum Institute (API) LNAPL Transmissivity Workbook API Workbook [API 2012]) and a modified API Workbook for DNAPL (Nelson and Smith 2016 Nelson 2017) using modified versions of the Bouwer and Rice (BampR) (1976) and Cooper and Jacob (CampJ) (1946)Jacob and Lohman (1952) slug test method Each of the available solutions involves different assumptions regarding the response of fluid levels within the well to the removal of NAPL Where possible baildown test data are evaluated using each of the solutions If data are not suitable for analysis using one or more of the methods only results obtained using the applicable analysis methods will be reported

Some baildown tests do not generate data that can be analyzed using the API Workbook This generally occurs when there is limited NAPL thickness at test initiation the NAPL in the well is not in equilibrium with the formation or the NAPL discharge into the well cannot be related to the NAPL drawdown induced during the test In cases where the NAPL discharge trend is difficult to identify transmissivity can be estimated

using the manual skimming evaluation method (Section 32) a constant rate of NAPL discharge to the well derived from test data and an average NAPL drawdown induced during that period of the test

Data analysis options in the API Workbook include a data time cut and drawdown adjustment that can be applied as needed A data time cut is required for nearly every test where early-time hydraulic response data representing filter pack drainage is removed from analysis Initial filter pack drainage does not represent formation drainage and an analysis incorporating these data will lead to erroneous results The drawdown adjustment is only applied if NAPL in the well at the time of test initiation is not in equilibrium with NAPL in the formation resulting in a clear trend of zero NAPL discharge at a non-zero (positive or negative) value for NAPL drawdown The drawdown adjustment is applied to reconcile the calculated drawdown with the observed trend toward zero discharge Further information on the data time cut and drawdown adjustment is provided in the user guide for the API Workbook (API 2012)

32 LNAPL Manual Skimming Tests

LNAPL manual skimming tests involve repeated LNAPL recovery periods and thus may test a larger portion of the LNAPL-impacted formation Transmissivity estimates from manual LNAPL skimming tests are expected to correlate more strongly to results that would be expected for LNAPL recovery system operation

A manual skimming test consists of removing all LNAPL from a well gauging the well as the LNAPL recharges and removing LNAPL again before the NAPL thickness reaches 25 percent of the pre-test LNAPL thickness This process is repeated until the LNAPL removal rate stabilizes In general a minimum stable LNAPL thickness of about 03 ft is necessary to perform a manual skimming test

Analysis of the manual LNAPL skimming test data can be completed using Equation 1 (ASTM 2013)

Qn = measured LNAPL recovery rate cubic feet per day (feet3day)

ROI = radius of influence feet

rw = well radius feet

sn = LNAPL drawdown feet

The radius of influence is difficult to estimate for a manual skimming test however because the term occurs within a logarithmic function in Equation 1 the value is not critical for estimating LNAPL transmissivity For this evaluation the value of the term ldquoln (ROIrw)rdquo was assumed to be 46 per ASTM guidance (ASTM 2013)

(MCP) That guidance document provides details and discussion related to the use of transmissivity testing as part of an overall demonstration of LNAPL recoverability including the feasibility of continued system operation Per the September 30 2016 proposal to EPA and consistent with state regulatory guidance LNAPL transmissivity testing and DNAPL transmissivity testing was performed at select locations within GMA 1 and GMA 3 The results of the tests are summarized below

331 GMA 1 East Street Area 1

Transmissivity testing was proposed to be completed at wells 105 106 and ESA1S-45 based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet Initial gauging prior to the event was conducted during which only one well 106 had sufficient LNAPL thickness to perform a LNAPL baildown test Wells 105 and ESA1S-45 had measurable LNAPL thicknesses of 021 and 016 feet respectively during the initial gauging event Over the course of approximately 8-weeks LNAPL thicknesses in those wells did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively (Table 1) Given the historical recovery volume (Arcadis 2017a) and small vertical interval of measurable LNAPL in each of these wells continued recovery is unlikely to produce a volume that would beneficially reduce LNAPL mass in the subsurface Field data for the LNAPL baildown test at well 106 is included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown test at 106 are included as Appendix C A summary of results is included on Table 2 and is shown on Figure 2

An LNAPL baildown test was initiated at well 106 in January 2017 Prior to the start of the test fluid level gauging and depth to bottom measurements were collected at which point an obstruction or anomaly was detected at a depth of 966 feet bgs while the well depth is typically measured as approximately 175 feet bgs This anomaly has not been observed previously and the fall 2016 and spring 2017 measurements were able to reach the bottom of the well While initial LNAPL thickness could not be determined because the obstruction was above the NAPL-water interface the depth to the NAPL-air interface (depth to LNAPL) was determined and is assumed to represent equilibrium conditions Fluid level measurements were collected periodically for approximately eight hours at the well LNAPL recharged to about 43 of initial measured thickness by the end of the first test day so periodic gauging for LNAPL thickness over the following eight weeks to evaluate further recharge was conducted While water table fluctuations were observed during this time which are expected LNAPL thickness had not returned to the initial thickness observed as of March 2017 (Table 1) Because of the limited LNAPL recharge the baildown test data were not suitable for evaluation by the standard analytical solutions Instead they were analyzed using Eq 1 and a constant rate of NAPL discharge to the well estimated from test data that likely represents formation drainage and an average NAPL drawdown induced during that period of the test This evaluation indicates a transmissivity of about 001 ft2day well below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016)

332 GMA1 Newell Street Area II

DNAPL recoverability testing was proposed to be completed at wells N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14 based on a review of historical gauging data that indicated measurable DNAPL was present at thicknesses greater than 03 feet and at a depth greater than the documented top of sump indicating a hydraulic connection at the time of the test between DNAPL present

in the wells and DNAPL in the surrounding formation Initial gauging was conducted prior to the event during which five of six wells met the thickness and formation connection criteria required to perform a baildown test at the well Baildown tests were completed in January 2017 While on-going gauging was conducted at the area wells for approximately eight weeks following the tests to assess recharge conditions in the well the portion of the tests that were able be evaluated quantitively ranged from approximately four to 28 hours Field data for the DNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for DNAPL baildown tests are included as Appendix C A summary of results is included on Tables 2 and 3 and are shown on Figure 2

Quantitative transmissivity evaluations were completed for four wells N2SC-1I N2SC-1I(R) N2SC-03I(R) and N2SC-14 based on the results of the tests and subsequent gauging At all four wells the tests were analyzed using the API Workbook to determine a transmissivity at the well At three wells a constant NAPL dischargedrawdown analysis was also conducted for a portion of the test where test data likely represents formation drainage

Well N2SC-1I Baildown test results at well N2SC-1I were analyzed using the API Workbook (both BampR and CampJ methods) resulting in estimated transmissivity values above the criterion of recoverability of 08 ft2day The average transmissivity value was 28 ft2day though during the initial purge of DNAPL from the well less than 12 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered Most if not all of the recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-1I(R) which is only several feet away and screened across a similar interval indicated transmissivity values well below the 08 ft2day criteria which is further evidence that calculated recoverability was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-1I(R) Baildown tests at well N2SC-1I(R) were analyzed using both the API Workbook and a constant NAPL dischargedrawdown analysis resulting in estimated transmissivity values below the criterion of recoverability of 08 ft2day The average transmissivity value was 01 ft2day indicating DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I DNAPL was measured in well N2SC-03I at a depth below the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I(R) Baildown test results at well N2SC-03I(R) were analyzed using the API Workbook (both BampR and CampJ methods) and through a constant NAPL dischargedrawdown analysis Transmissivities determined at the well include one value above the 08 ft2day criteria and an average transmissivity of 05 ft2day During the initial purge of DNAPL from the well less

than 25 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered The recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-03I which is only several feet away and screened across a similar interval indicated no recharge from the formation following an initial recovery which is further evidence that calculated recoverability for well N2SC-03I(R) was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-13I Following initial recovery DNAPL was not measured in well N2SC-13I at a depth above the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-14 Gauging data collected from well N2SC-14 following the removal of DNAPL in the well sump indicated measurable DNAPL was present within the well screen interval only once during the initial and subsequent gauging that was conducted periodically for eight weeks following the initiation of the test Where DNAPL recharge is gauged only in the well sump evaluation by the API Workbook is not appropriate and an estimated transmissivity may be derived by utilizing a DNAPL drawdown consistent with the stable thickness in the screened interval and a constant DNAPL discharge determined through a calculation of measured volume of recharge to the well over a given time Late time series data was used to determine DNAPL discharge and DNAPL drawdown this way resulting in a transmissivity of 03 ft2day at the well below the criterion of recoverability of 08 ft2day These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

333 GMA3

Transmissivity testing was proposed to be completed at 13 wells in the GMA3 area based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet However during the pretest gauging only wells 51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17 had sufficient LNAPL thickness to perform either a LNAPL baildown or manual skimming test Over the course of approximately 8-weeks LNAPL thicknesses in the six wells without adequate thickness did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively Field data for the LNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown tests are included as Appendix C and manual skimming test input and output data are included as Appendix D and E respectively A summary of results is included on Tables 2 and 3 and are shown on Figure 3

Quantitative transmissivity evaluation was completed for all wells based on the results of the tests and subsequent gauging At two wells 51-08 and 51-19 the tests were analyzed using the BampR and CampJ

methods in the API Workbook to determine a transmissivity at the well (Table 2) Estimated transmissivity values were below the MassDEP and ITRC criterion of recoverability of 08 ft2day

Manual skimming tests were completed at 59-03R GMA3-12 and GMA-17 and analysis of the data was completed using Equation 1 (ASTM 2013) to estimate a transmissivity at each well The tests were completed in January 2017 and ranged in duration from approximately five to nine hours Periodic purging of LNAPL was performed to maintain an LNAPL thickness of less than 25 percent of the initial gauged thickness and only data that met that criteria were used in the analysis LNAPL transmissivity estimates for all three wells are below the criterion of recoverability of 08 ft2day indicating that continued hydraulic operations would not result in beneficial recovery of LNAPL from the subsurface near the wells

Where baildown test data are not suitable for analysis by the Bower amp Rice and Cooper amp Jacob method the data are analyzed using Eq 1 an estimated constant rate of NAPL discharge to the well from test data that best represents formation drainage and an average NAPL drawdown induced during that period of the test Data collected during tests conducted at wells 51-17 and 51-21 were evaluated in this manner The LNAPL transmissivity estimates 004 ft2day and 0002 ft2day respectively are both below the criterion of recoverability of 08 ft2day

4 CONCLUSIONS

Evaluation of the baildown and manual skimming tests indicate NAPL transmissivities were generally below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016) with two noted exceptions at wells N2SC-1I(R) and N2SC-03I(R) where only a small percentage of the total casing and filter pack volume was able to be removed at the start of the test likely resulting in initial filter pack drainage

Transmissivity calculations from LNAPL baildown tests LNAPL manual skimming tests and DNAPL baildown tests completed in GMA1 and GMA3 generally indicate that NAPL recovery potential at the Site from these specific systems are negligible NAPL transmissivities are below the criterion of recoverability of 08 ft2day (ITRC 2009) with the exception of well N2SC-01I and N2SC-03I(R) in GMA1 The estimated transmissivities at these two wells likely represent filter pack drainage and little if any of the longer-term potential for NAPL recoverability from the formation At N2SC-03I(R) the NAPL transmissivity estimate for only one of the three analysis methods exceeds the MassDEP and ITRC criterion Additionally tests conducted at or near wells with recovery systems in place indicate that further NAPL recovery will not provide a meaningful benefit for the Site A summary of activities conducted and conclusions reached for each area is included below

41 Conclusions for GMA1 East Street Area 1

Of the three wells proposed for testing only one well (106) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

The LNAPL transmissivity estimate for this area is 001 ft2day

42 Conclusions for GMA1 Newell Street Area II

Of the wells proposed for testing all six (N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14) met the criterion to be tested

DNAPL transmissivity estimates for this area ranged from near-zero to 28 ft2day with five of the six estimates below the 08 ft2day MassDEP and ITRC criterion The exceedance to the criteria is likely the result of initial filter pack drainage

43 Conclusions for GMA3

Of the 13 wells proposed for testing in this area only seven wells (51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

LNAPL transmissivity estimates for this area ranged from 0002 ft2day to 04 ft2day

5 RECOMMENDATIONS

Currently in-well NAPL thickness is the criteria by which NAPL recovery at a well is determined to be required In accordance with recently developed standards and guidance endorsed by ITRC ASTM and a number of state agencies including MassDEP it is recommended that NAPL transmissivity data be used to develop a riskbenefit-based approach to NAPL recovery and management at the Site NAPL transmissivity rather than measured NAPL thickness is the most appropriate indicator of the potential for NAPL recovery to provide beneficial reduction in NAPL mass Specific recommendations for changes to the recovery criteria and management program are provided below

51 Recommendations for GMA1 East Street Area 1

Operation of the LNAPL recovery systems in this area should be discontinued because recovery by hydraulic methods in this area is unlikely to beneficially reduce LNAPL in the subsurface

LNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

Fluid level gauging should continue within the well network to monitor LNAPL thickness in wells where it has historically been observed

52 Recommendations for GMA1 Newell Street Area II

Operation of the DNAPL recovery system should be discontinued because DNAPL recovery by hydraulic methods in this area is unlikely to beneficially reduce NAPL in the subsurface

Periodic DNAPL recovery by manual bailing should be continued at wells where transmissivity is found to be greater than 08 ft2day when Site-specific recovery criteria are met

DNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

1 INTRODUCTION

Arcadis US Inc (Arcadis) has prepared this memorandum on behalf of General Electric Company (GE) at the request of the US Environmental Protection Agency (EPA) to present additional data related to both Light Non-Aqueous Phase Liquid (LNAPL) and Dense Non-Aqueous Phase Liquid (DNAPL) recoverability within portions of GErsquos Pittsfield MA site (Figure 1) In the September 30 2016 proposal to EPA entitled ldquoGE-PittsfieldHousatonic River Site (the ldquoSiterdquo) Evaluation of NAPL Recovery Systems ndash Proposed Activities Groundwater Management Areas 1 and 3rdquo GE presented an evaluation approach involving NAPL transmissivity testing including collecting evaluating and reporting additional transmissivity data to evaluate the effectiveness of automated or manual NAPL recovery for these specified areas This memorandum has been prepared to present the results of the NAPL recovery data collected between January 18 2017 and April 20 2017 and provide recommendations for program modifications

11 Background

Since the onset of NAPL recovery at the Site over 35 years ago GE has continuously monitored assessed upgraded expanded and optimized its NAPL recovery efforts Over this time there has been success in 1) removing NAPL from the Site (to varying degrees based on the recovery system) 2) reducing the overall extent and quantity of mobile NAPL that remains within the Site and 3) maintaining compliance with the applicable Performance Standards established in the October 2000 Consent Decree (CD) For certain recovery systems the NAPL recovery rates have diminished over time to the point where limited NAPL recovery is currently being realized This evaluation was performed in accordance with Technical Attachment H of Appendix E to the CD to assess recovery systems at the Site and propose enhancements or modifications as necessary to meet the long-term goal of maximizing NAPL recovery and eliminating mobile NAPL These NAPL transmissivity results are used to evaluate whether NAPL recovery via hydraulic operations remains a feasible and practical alternative for NAPL mass reduction A NAPL transmissivity of 08 square feet per day (ft2day) is used as the criterion for practical NAPL recoverability (ITRC 2009 MassDEP 2016) Below this value hydraulic recovery will not lead to remedial benefit and is not likely to substantially reduce the overall NAPL mass in the subsurface NAPL transmissivity data was collected at the Site beginning in January 2017 and included the completion of five LNAPL baildown tests six DNAPL baildown tests and three LNAPL manual skimming tests

2 METHODOLOGY

This NAPL recoverability assessment is based on NAPL transmissivity measurements Several methods were applied to estimate LNAPL transmissivity including

LNAPL baildown tests

DNAPL baildown tests

LNAPL manual skimming tests

The following sections describe the specific methodology for each of the lines of evidence used in this NAPL recoverability assessment The methodology for LNAPL transmissivity data collection and analysis

are consistent with the ASTM International (ASTM) Standard Guide for Estimation of LNAPL Transmissivity E2856-13 (ASTM 2013)

While no industry-wide standards or test methods currently exist for DNAPL baildown testing the same principles of LNAPL mobility and recoverability are appropriate to evaluate DNAPL mobility (Nelson and Smith 2016 Nelson 2017) Testing was subject to the same pre-test conditions (eg stability of NAPL thickness and no influence from an active recovery system) and testing methods (eg baildown testing) as those conducted for LNAPL assessment Also the active system operations were suspended prior to the test

3 NAPL FIELD TRANSMISSIVITY

The recoverability of NAPL is influenced by many factors including NAPL saturation in the impacted soil soil permeability and physical properties of the NAPL Transmissivity represents the volumetric rate of NAPL flow through a unit width of porous media per unit time under a unit hydraulic gradient A direct mathematical relationship exists between NAPL transmissivity and the rate of NAPL flow into a well therefore it is an ideal parameter for assessing NAPL recoverability NAPL transmissivity calculations inherently account for the combined effects of aquifer matrix permeability NAPL physical properties and the relative proportion of pore space occupied by NAPL within a specified vertical interval of aquifer material Five NAPL samples from wells representative of site conditions (51-08 51-19 106 N2SC-13I and N2SC-01I) were collected and submitted to PTS Laboratories Inc in Santa Fe Springs California for viscosity density and specific gravity analysis Results of the analysis are provided in Appendix A

31 NAPL Baildown Tests

A NAPL baildown test is initiated by quickly removing accumulated LNAPL from a well The rate of NAPL flow into the well is a function of soil and NAPL properties as well as the magnitude of the initial hydraulic gradient toward the well developed during NAPL removal The baildown test response is influenced by the prevalent fluid levels at the time of testing Baildown tests were performed in areas GMA1 (East Street Area 1 and Newell Street Area II) and GMA3 at the Site to describe the range of NAPL transmissivities under different fluid level conditions In general a minimum stable NAPL thickness of about 05 ft is necessary to perform a baildown test

Baildown tests are analyzed in the American Petroleum Institute (API) LNAPL Transmissivity Workbook API Workbook [API 2012]) and a modified API Workbook for DNAPL (Nelson and Smith 2016 Nelson 2017) using modified versions of the Bouwer and Rice (BampR) (1976) and Cooper and Jacob (CampJ) (1946)Jacob and Lohman (1952) slug test method Each of the available solutions involves different assumptions regarding the response of fluid levels within the well to the removal of NAPL Where possible baildown test data are evaluated using each of the solutions If data are not suitable for analysis using one or more of the methods only results obtained using the applicable analysis methods will be reported

Some baildown tests do not generate data that can be analyzed using the API Workbook This generally occurs when there is limited NAPL thickness at test initiation the NAPL in the well is not in equilibrium with the formation or the NAPL discharge into the well cannot be related to the NAPL drawdown induced during the test In cases where the NAPL discharge trend is difficult to identify transmissivity can be estimated

using the manual skimming evaluation method (Section 32) a constant rate of NAPL discharge to the well derived from test data and an average NAPL drawdown induced during that period of the test

Data analysis options in the API Workbook include a data time cut and drawdown adjustment that can be applied as needed A data time cut is required for nearly every test where early-time hydraulic response data representing filter pack drainage is removed from analysis Initial filter pack drainage does not represent formation drainage and an analysis incorporating these data will lead to erroneous results The drawdown adjustment is only applied if NAPL in the well at the time of test initiation is not in equilibrium with NAPL in the formation resulting in a clear trend of zero NAPL discharge at a non-zero (positive or negative) value for NAPL drawdown The drawdown adjustment is applied to reconcile the calculated drawdown with the observed trend toward zero discharge Further information on the data time cut and drawdown adjustment is provided in the user guide for the API Workbook (API 2012)

32 LNAPL Manual Skimming Tests

LNAPL manual skimming tests involve repeated LNAPL recovery periods and thus may test a larger portion of the LNAPL-impacted formation Transmissivity estimates from manual LNAPL skimming tests are expected to correlate more strongly to results that would be expected for LNAPL recovery system operation

A manual skimming test consists of removing all LNAPL from a well gauging the well as the LNAPL recharges and removing LNAPL again before the NAPL thickness reaches 25 percent of the pre-test LNAPL thickness This process is repeated until the LNAPL removal rate stabilizes In general a minimum stable LNAPL thickness of about 03 ft is necessary to perform a manual skimming test

Analysis of the manual LNAPL skimming test data can be completed using Equation 1 (ASTM 2013)

ln

R w

OI r T Q Equation 1

Qn = measured LNAPL recovery rate cubic feet per day (feet3day)

ROI = radius of influence feet

rw = well radius feet

sn = LNAPL drawdown feet

The radius of influence is difficult to estimate for a manual skimming test however because the term occurs within a logarithmic function in Equation 1 the value is not critical for estimating LNAPL transmissivity For this evaluation the value of the term ldquoln (ROIrw)rdquo was assumed to be 46 per ASTM guidance (ASTM 2013)

33 Field Data Collection and Evaluation

The Massachusetts Department of Environmental Protection (MassDEP) has prepared a document entitled ldquoLight Non-Aqueous Phase Liquids (LNAPL) and the MCP Guidance for Site Assessment and Closurerdquo (MassDEP LNAPL Guidance) for consideration at sites regulated by the Massachusetts Contingency Plan

(MCP) That guidance document provides details and discussion related to the use of transmissivity testing as part of an overall demonstration of LNAPL recoverability including the feasibility of continued system operation Per the September 30 2016 proposal to EPA and consistent with state regulatory guidance LNAPL transmissivity testing and DNAPL transmissivity testing was performed at select locations within GMA 1 and GMA 3 The results of the tests are summarized below

331 GMA 1 East Street Area 1

Transmissivity testing was proposed to be completed at wells 105 106 and ESA1S-45 based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet Initial gauging prior to the event was conducted during which only one well 106 had sufficient LNAPL thickness to perform a LNAPL baildown test Wells 105 and ESA1S-45 had measurable LNAPL thicknesses of 021 and 016 feet respectively during the initial gauging event Over the course of approximately 8-weeks LNAPL thicknesses in those wells did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively (Table 1) Given the historical recovery volume (Arcadis 2017a) and small vertical interval of measurable LNAPL in each of these wells continued recovery is unlikely to produce a volume that would beneficially reduce LNAPL mass in the subsurface Field data for the LNAPL baildown test at well 106 is included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown test at 106 are included as Appendix C A summary of results is included on Table 2 and is shown on Figure 2

An LNAPL baildown test was initiated at well 106 in January 2017 Prior to the start of the test fluid level gauging and depth to bottom measurements were collected at which point an obstruction or anomaly was detected at a depth of 966 feet bgs while the well depth is typically measured as approximately 175 feet bgs This anomaly has not been observed previously and the fall 2016 and spring 2017 measurements were able to reach the bottom of the well While initial LNAPL thickness could not be determined because the obstruction was above the NAPL-water interface the depth to the NAPL-air interface (depth to LNAPL) was determined and is assumed to represent equilibrium conditions Fluid level measurements were collected periodically for approximately eight hours at the well LNAPL recharged to about 43 of initial measured thickness by the end of the first test day so periodic gauging for LNAPL thickness over the following eight weeks to evaluate further recharge was conducted While water table fluctuations were observed during this time which are expected LNAPL thickness had not returned to the initial thickness observed as of March 2017 (Table 1) Because of the limited LNAPL recharge the baildown test data were not suitable for evaluation by the standard analytical solutions Instead they were analyzed using Eq 1 and a constant rate of NAPL discharge to the well estimated from test data that likely represents formation drainage and an average NAPL drawdown induced during that period of the test This evaluation indicates a transmissivity of about 001 ft2day well below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016)

332 GMA1 Newell Street Area II

DNAPL recoverability testing was proposed to be completed at wells N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14 based on a review of historical gauging data that indicated measurable DNAPL was present at thicknesses greater than 03 feet and at a depth greater than the documented top of sump indicating a hydraulic connection at the time of the test between DNAPL present

in the wells and DNAPL in the surrounding formation Initial gauging was conducted prior to the event during which five of six wells met the thickness and formation connection criteria required to perform a baildown test at the well Baildown tests were completed in January 2017 While on-going gauging was conducted at the area wells for approximately eight weeks following the tests to assess recharge conditions in the well the portion of the tests that were able be evaluated quantitively ranged from approximately four to 28 hours Field data for the DNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for DNAPL baildown tests are included as Appendix C A summary of results is included on Tables 2 and 3 and are shown on Figure 2

Quantitative transmissivity evaluations were completed for four wells N2SC-1I N2SC-1I(R) N2SC-03I(R) and N2SC-14 based on the results of the tests and subsequent gauging At all four wells the tests were analyzed using the API Workbook to determine a transmissivity at the well At three wells a constant NAPL dischargedrawdown analysis was also conducted for a portion of the test where test data likely represents formation drainage

Well N2SC-1I Baildown test results at well N2SC-1I were analyzed using the API Workbook (both BampR and CampJ methods) resulting in estimated transmissivity values above the criterion of recoverability of 08 ft2day The average transmissivity value was 28 ft2day though during the initial purge of DNAPL from the well less than 12 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered Most if not all of the recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-1I(R) which is only several feet away and screened across a similar interval indicated transmissivity values well below the 08 ft2day criteria which is further evidence that calculated recoverability was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-1I(R) Baildown tests at well N2SC-1I(R) were analyzed using both the API Workbook and a constant NAPL dischargedrawdown analysis resulting in estimated transmissivity values below the criterion of recoverability of 08 ft2day The average transmissivity value was 01 ft2day indicating DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I DNAPL was measured in well N2SC-03I at a depth below the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I(R) Baildown test results at well N2SC-03I(R) were analyzed using the API Workbook (both BampR and CampJ methods) and through a constant NAPL dischargedrawdown analysis Transmissivities determined at the well include one value above the 08 ft2day criteria and an average transmissivity of 05 ft2day During the initial purge of DNAPL from the well less

than 25 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered The recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-03I which is only several feet away and screened across a similar interval indicated no recharge from the formation following an initial recovery which is further evidence that calculated recoverability for well N2SC-03I(R) was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-13I Following initial recovery DNAPL was not measured in well N2SC-13I at a depth above the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-14 Gauging data collected from well N2SC-14 following the removal of DNAPL in the well sump indicated measurable DNAPL was present within the well screen interval only once during the initial and subsequent gauging that was conducted periodically for eight weeks following the initiation of the test Where DNAPL recharge is gauged only in the well sump evaluation by the API Workbook is not appropriate and an estimated transmissivity may be derived by utilizing a DNAPL drawdown consistent with the stable thickness in the screened interval and a constant DNAPL discharge determined through a calculation of measured volume of recharge to the well over a given time Late time series data was used to determine DNAPL discharge and DNAPL drawdown this way resulting in a transmissivity of 03 ft2day at the well below the criterion of recoverability of 08 ft2day These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

333 GMA3

Transmissivity testing was proposed to be completed at 13 wells in the GMA3 area based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet However during the pretest gauging only wells 51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17 had sufficient LNAPL thickness to perform either a LNAPL baildown or manual skimming test Over the course of approximately 8-weeks LNAPL thicknesses in the six wells without adequate thickness did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively Field data for the LNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown tests are included as Appendix C and manual skimming test input and output data are included as Appendix D and E respectively A summary of results is included on Tables 2 and 3 and are shown on Figure 3

Quantitative transmissivity evaluation was completed for all wells based on the results of the tests and subsequent gauging At two wells 51-08 and 51-19 the tests were analyzed using the BampR and CampJ

methods in the API Workbook to determine a transmissivity at the well (Table 2) Estimated transmissivity values were below the MassDEP and ITRC criterion of recoverability of 08 ft2day

Manual skimming tests were completed at 59-03R GMA3-12 and GMA-17 and analysis of the data was completed using Equation 1 (ASTM 2013) to estimate a transmissivity at each well The tests were completed in January 2017 and ranged in duration from approximately five to nine hours Periodic purging of LNAPL was performed to maintain an LNAPL thickness of less than 25 percent of the initial gauged thickness and only data that met that criteria were used in the analysis LNAPL transmissivity estimates for all three wells are below the criterion of recoverability of 08 ft2day indicating that continued hydraulic operations would not result in beneficial recovery of LNAPL from the subsurface near the wells

Where baildown test data are not suitable for analysis by the Bower amp Rice and Cooper amp Jacob method the data are analyzed using Eq 1 an estimated constant rate of NAPL discharge to the well from test data that best represents formation drainage and an average NAPL drawdown induced during that period of the test Data collected during tests conducted at wells 51-17 and 51-21 were evaluated in this manner The LNAPL transmissivity estimates 004 ft2day and 0002 ft2day respectively are both below the criterion of recoverability of 08 ft2day

4 CONCLUSIONS

Evaluation of the baildown and manual skimming tests indicate NAPL transmissivities were generally below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016) with two noted exceptions at wells N2SC-1I(R) and N2SC-03I(R) where only a small percentage of the total casing and filter pack volume was able to be removed at the start of the test likely resulting in initial filter pack drainage

Transmissivity calculations from LNAPL baildown tests LNAPL manual skimming tests and DNAPL baildown tests completed in GMA1 and GMA3 generally indicate that NAPL recovery potential at the Site from these specific systems are negligible NAPL transmissivities are below the criterion of recoverability of 08 ft2day (ITRC 2009) with the exception of well N2SC-01I and N2SC-03I(R) in GMA1 The estimated transmissivities at these two wells likely represent filter pack drainage and little if any of the longer-term potential for NAPL recoverability from the formation At N2SC-03I(R) the NAPL transmissivity estimate for only one of the three analysis methods exceeds the MassDEP and ITRC criterion Additionally tests conducted at or near wells with recovery systems in place indicate that further NAPL recovery will not provide a meaningful benefit for the Site A summary of activities conducted and conclusions reached for each area is included below

41 Conclusions for GMA1 East Street Area 1

Of the three wells proposed for testing only one well (106) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

The LNAPL transmissivity estimate for this area is 001 ft2day

42 Conclusions for GMA1 Newell Street Area II

Of the wells proposed for testing all six (N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14) met the criterion to be tested

DNAPL transmissivity estimates for this area ranged from near-zero to 28 ft2day with five of the six estimates below the 08 ft2day MassDEP and ITRC criterion The exceedance to the criteria is likely the result of initial filter pack drainage

43 Conclusions for GMA3

Of the 13 wells proposed for testing in this area only seven wells (51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

LNAPL transmissivity estimates for this area ranged from 0002 ft2day to 04 ft2day

5 RECOMMENDATIONS

Currently in-well NAPL thickness is the criteria by which NAPL recovery at a well is determined to be required In accordance with recently developed standards and guidance endorsed by ITRC ASTM and a number of state agencies including MassDEP it is recommended that NAPL transmissivity data be used to develop a riskbenefit-based approach to NAPL recovery and management at the Site NAPL transmissivity rather than measured NAPL thickness is the most appropriate indicator of the potential for NAPL recovery to provide beneficial reduction in NAPL mass Specific recommendations for changes to the recovery criteria and management program are provided below

51 Recommendations for GMA1 East Street Area 1

Operation of the LNAPL recovery systems in this area should be discontinued because recovery by hydraulic methods in this area is unlikely to beneficially reduce LNAPL in the subsurface

LNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

Fluid level gauging should continue within the well network to monitor LNAPL thickness in wells where it has historically been observed

52 Recommendations for GMA1 Newell Street Area II

Operation of the DNAPL recovery system should be discontinued because DNAPL recovery by hydraulic methods in this area is unlikely to beneficially reduce NAPL in the subsurface

Periodic DNAPL recovery by manual bailing should be continued at wells where transmissivity is found to be greater than 08 ft2day when Site-specific recovery criteria are met

DNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

Arcadis US Inc (Arcadis) has prepared this memorandum on behalf of General Electric Company (GE) at the request of the US Environmental Protection Agency (EPA) to present additional data related to both Light Non-Aqueous Phase Liquid (LNAPL) and Dense Non-Aqueous Phase Liquid (DNAPL) recoverability within portions of GErsquos Pittsfield MA site (Figure 1) In the September 30 2016 proposal to EPA entitled ldquoGE-PittsfieldHousatonic River Site (the ldquoSiterdquo) Evaluation of NAPL Recovery Systems ndash Proposed Activities Groundwater Management Areas 1 and 3rdquo GE presented an evaluation approach involving NAPL transmissivity testing including collecting evaluating and reporting additional transmissivity data to evaluate the effectiveness of automated or manual NAPL recovery for these specified areas This memorandum has been prepared to present the results of the NAPL recovery data collected between January 18 2017 and April 20 2017 and provide recommendations for program modifications

11 Background

Since the onset of NAPL recovery at the Site over 35 years ago GE has continuously monitored assessed upgraded expanded and optimized its NAPL recovery efforts Over this time there has been success in 1) removing NAPL from the Site (to varying degrees based on the recovery system) 2) reducing the overall extent and quantity of mobile NAPL that remains within the Site and 3) maintaining compliance with the applicable Performance Standards established in the October 2000 Consent Decree (CD) For certain recovery systems the NAPL recovery rates have diminished over time to the point where limited NAPL recovery is currently being realized This evaluation was performed in accordance with Technical Attachment H of Appendix E to the CD to assess recovery systems at the Site and propose enhancements or modifications as necessary to meet the long-term goal of maximizing NAPL recovery and eliminating mobile NAPL These NAPL transmissivity results are used to evaluate whether NAPL recovery via hydraulic operations remains a feasible and practical alternative for NAPL mass reduction A NAPL transmissivity of 08 square feet per day (ft2day) is used as the criterion for practical NAPL recoverability (ITRC 2009 MassDEP 2016) Below this value hydraulic recovery will not lead to remedial benefit and is not likely to substantially reduce the overall NAPL mass in the subsurface NAPL transmissivity data was collected at the Site beginning in January 2017 and included the completion of five LNAPL baildown tests six DNAPL baildown tests and three LNAPL manual skimming tests

2 METHODOLOGY

This NAPL recoverability assessment is based on NAPL transmissivity measurements Several methods were applied to estimate LNAPL transmissivity including

LNAPL baildown tests

DNAPL baildown tests

LNAPL manual skimming tests

The following sections describe the specific methodology for each of the lines of evidence used in this NAPL recoverability assessment The methodology for LNAPL transmissivity data collection and analysis

are consistent with the ASTM International (ASTM) Standard Guide for Estimation of LNAPL Transmissivity E2856-13 (ASTM 2013)

While no industry-wide standards or test methods currently exist for DNAPL baildown testing the same principles of LNAPL mobility and recoverability are appropriate to evaluate DNAPL mobility (Nelson and Smith 2016 Nelson 2017) Testing was subject to the same pre-test conditions (eg stability of NAPL thickness and no influence from an active recovery system) and testing methods (eg baildown testing) as those conducted for LNAPL assessment Also the active system operations were suspended prior to the test

3 NAPL FIELD TRANSMISSIVITY

The recoverability of NAPL is influenced by many factors including NAPL saturation in the impacted soil soil permeability and physical properties of the NAPL Transmissivity represents the volumetric rate of NAPL flow through a unit width of porous media per unit time under a unit hydraulic gradient A direct mathematical relationship exists between NAPL transmissivity and the rate of NAPL flow into a well therefore it is an ideal parameter for assessing NAPL recoverability NAPL transmissivity calculations inherently account for the combined effects of aquifer matrix permeability NAPL physical properties and the relative proportion of pore space occupied by NAPL within a specified vertical interval of aquifer material Five NAPL samples from wells representative of site conditions (51-08 51-19 106 N2SC-13I and N2SC-01I) were collected and submitted to PTS Laboratories Inc in Santa Fe Springs California for viscosity density and specific gravity analysis Results of the analysis are provided in Appendix A

31 NAPL Baildown Tests

A NAPL baildown test is initiated by quickly removing accumulated LNAPL from a well The rate of NAPL flow into the well is a function of soil and NAPL properties as well as the magnitude of the initial hydraulic gradient toward the well developed during NAPL removal The baildown test response is influenced by the prevalent fluid levels at the time of testing Baildown tests were performed in areas GMA1 (East Street Area 1 and Newell Street Area II) and GMA3 at the Site to describe the range of NAPL transmissivities under different fluid level conditions In general a minimum stable NAPL thickness of about 05 ft is necessary to perform a baildown test

Baildown tests are analyzed in the American Petroleum Institute (API) LNAPL Transmissivity Workbook API Workbook [API 2012]) and a modified API Workbook for DNAPL (Nelson and Smith 2016 Nelson 2017) using modified versions of the Bouwer and Rice (BampR) (1976) and Cooper and Jacob (CampJ) (1946)Jacob and Lohman (1952) slug test method Each of the available solutions involves different assumptions regarding the response of fluid levels within the well to the removal of NAPL Where possible baildown test data are evaluated using each of the solutions If data are not suitable for analysis using one or more of the methods only results obtained using the applicable analysis methods will be reported

Some baildown tests do not generate data that can be analyzed using the API Workbook This generally occurs when there is limited NAPL thickness at test initiation the NAPL in the well is not in equilibrium with the formation or the NAPL discharge into the well cannot be related to the NAPL drawdown induced during the test In cases where the NAPL discharge trend is difficult to identify transmissivity can be estimated

using the manual skimming evaluation method (Section 32) a constant rate of NAPL discharge to the well derived from test data and an average NAPL drawdown induced during that period of the test

Data analysis options in the API Workbook include a data time cut and drawdown adjustment that can be applied as needed A data time cut is required for nearly every test where early-time hydraulic response data representing filter pack drainage is removed from analysis Initial filter pack drainage does not represent formation drainage and an analysis incorporating these data will lead to erroneous results The drawdown adjustment is only applied if NAPL in the well at the time of test initiation is not in equilibrium with NAPL in the formation resulting in a clear trend of zero NAPL discharge at a non-zero (positive or negative) value for NAPL drawdown The drawdown adjustment is applied to reconcile the calculated drawdown with the observed trend toward zero discharge Further information on the data time cut and drawdown adjustment is provided in the user guide for the API Workbook (API 2012)

32 LNAPL Manual Skimming Tests

LNAPL manual skimming tests involve repeated LNAPL recovery periods and thus may test a larger portion of the LNAPL-impacted formation Transmissivity estimates from manual LNAPL skimming tests are expected to correlate more strongly to results that would be expected for LNAPL recovery system operation

A manual skimming test consists of removing all LNAPL from a well gauging the well as the LNAPL recharges and removing LNAPL again before the NAPL thickness reaches 25 percent of the pre-test LNAPL thickness This process is repeated until the LNAPL removal rate stabilizes In general a minimum stable LNAPL thickness of about 03 ft is necessary to perform a manual skimming test

Analysis of the manual LNAPL skimming test data can be completed using Equation 1 (ASTM 2013)

Qn = measured LNAPL recovery rate cubic feet per day (feet3day)

ROI = radius of influence feet

rw = well radius feet

sn = LNAPL drawdown feet

The radius of influence is difficult to estimate for a manual skimming test however because the term occurs within a logarithmic function in Equation 1 the value is not critical for estimating LNAPL transmissivity For this evaluation the value of the term ldquoln (ROIrw)rdquo was assumed to be 46 per ASTM guidance (ASTM 2013)

(MCP) That guidance document provides details and discussion related to the use of transmissivity testing as part of an overall demonstration of LNAPL recoverability including the feasibility of continued system operation Per the September 30 2016 proposal to EPA and consistent with state regulatory guidance LNAPL transmissivity testing and DNAPL transmissivity testing was performed at select locations within GMA 1 and GMA 3 The results of the tests are summarized below

331 GMA 1 East Street Area 1

Transmissivity testing was proposed to be completed at wells 105 106 and ESA1S-45 based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet Initial gauging prior to the event was conducted during which only one well 106 had sufficient LNAPL thickness to perform a LNAPL baildown test Wells 105 and ESA1S-45 had measurable LNAPL thicknesses of 021 and 016 feet respectively during the initial gauging event Over the course of approximately 8-weeks LNAPL thicknesses in those wells did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively (Table 1) Given the historical recovery volume (Arcadis 2017a) and small vertical interval of measurable LNAPL in each of these wells continued recovery is unlikely to produce a volume that would beneficially reduce LNAPL mass in the subsurface Field data for the LNAPL baildown test at well 106 is included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown test at 106 are included as Appendix C A summary of results is included on Table 2 and is shown on Figure 2

An LNAPL baildown test was initiated at well 106 in January 2017 Prior to the start of the test fluid level gauging and depth to bottom measurements were collected at which point an obstruction or anomaly was detected at a depth of 966 feet bgs while the well depth is typically measured as approximately 175 feet bgs This anomaly has not been observed previously and the fall 2016 and spring 2017 measurements were able to reach the bottom of the well While initial LNAPL thickness could not be determined because the obstruction was above the NAPL-water interface the depth to the NAPL-air interface (depth to LNAPL) was determined and is assumed to represent equilibrium conditions Fluid level measurements were collected periodically for approximately eight hours at the well LNAPL recharged to about 43 of initial measured thickness by the end of the first test day so periodic gauging for LNAPL thickness over the following eight weeks to evaluate further recharge was conducted While water table fluctuations were observed during this time which are expected LNAPL thickness had not returned to the initial thickness observed as of March 2017 (Table 1) Because of the limited LNAPL recharge the baildown test data were not suitable for evaluation by the standard analytical solutions Instead they were analyzed using Eq 1 and a constant rate of NAPL discharge to the well estimated from test data that likely represents formation drainage and an average NAPL drawdown induced during that period of the test This evaluation indicates a transmissivity of about 001 ft2day well below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016)

332 GMA1 Newell Street Area II

DNAPL recoverability testing was proposed to be completed at wells N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14 based on a review of historical gauging data that indicated measurable DNAPL was present at thicknesses greater than 03 feet and at a depth greater than the documented top of sump indicating a hydraulic connection at the time of the test between DNAPL present

in the wells and DNAPL in the surrounding formation Initial gauging was conducted prior to the event during which five of six wells met the thickness and formation connection criteria required to perform a baildown test at the well Baildown tests were completed in January 2017 While on-going gauging was conducted at the area wells for approximately eight weeks following the tests to assess recharge conditions in the well the portion of the tests that were able be evaluated quantitively ranged from approximately four to 28 hours Field data for the DNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for DNAPL baildown tests are included as Appendix C A summary of results is included on Tables 2 and 3 and are shown on Figure 2

Quantitative transmissivity evaluations were completed for four wells N2SC-1I N2SC-1I(R) N2SC-03I(R) and N2SC-14 based on the results of the tests and subsequent gauging At all four wells the tests were analyzed using the API Workbook to determine a transmissivity at the well At three wells a constant NAPL dischargedrawdown analysis was also conducted for a portion of the test where test data likely represents formation drainage

Well N2SC-1I Baildown test results at well N2SC-1I were analyzed using the API Workbook (both BampR and CampJ methods) resulting in estimated transmissivity values above the criterion of recoverability of 08 ft2day The average transmissivity value was 28 ft2day though during the initial purge of DNAPL from the well less than 12 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered Most if not all of the recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-1I(R) which is only several feet away and screened across a similar interval indicated transmissivity values well below the 08 ft2day criteria which is further evidence that calculated recoverability was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-1I(R) Baildown tests at well N2SC-1I(R) were analyzed using both the API Workbook and a constant NAPL dischargedrawdown analysis resulting in estimated transmissivity values below the criterion of recoverability of 08 ft2day The average transmissivity value was 01 ft2day indicating DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I DNAPL was measured in well N2SC-03I at a depth below the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I(R) Baildown test results at well N2SC-03I(R) were analyzed using the API Workbook (both BampR and CampJ methods) and through a constant NAPL dischargedrawdown analysis Transmissivities determined at the well include one value above the 08 ft2day criteria and an average transmissivity of 05 ft2day During the initial purge of DNAPL from the well less

than 25 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered The recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-03I which is only several feet away and screened across a similar interval indicated no recharge from the formation following an initial recovery which is further evidence that calculated recoverability for well N2SC-03I(R) was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-13I Following initial recovery DNAPL was not measured in well N2SC-13I at a depth above the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-14 Gauging data collected from well N2SC-14 following the removal of DNAPL in the well sump indicated measurable DNAPL was present within the well screen interval only once during the initial and subsequent gauging that was conducted periodically for eight weeks following the initiation of the test Where DNAPL recharge is gauged only in the well sump evaluation by the API Workbook is not appropriate and an estimated transmissivity may be derived by utilizing a DNAPL drawdown consistent with the stable thickness in the screened interval and a constant DNAPL discharge determined through a calculation of measured volume of recharge to the well over a given time Late time series data was used to determine DNAPL discharge and DNAPL drawdown this way resulting in a transmissivity of 03 ft2day at the well below the criterion of recoverability of 08 ft2day These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

333 GMA3

Transmissivity testing was proposed to be completed at 13 wells in the GMA3 area based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet However during the pretest gauging only wells 51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17 had sufficient LNAPL thickness to perform either a LNAPL baildown or manual skimming test Over the course of approximately 8-weeks LNAPL thicknesses in the six wells without adequate thickness did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively Field data for the LNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown tests are included as Appendix C and manual skimming test input and output data are included as Appendix D and E respectively A summary of results is included on Tables 2 and 3 and are shown on Figure 3

Quantitative transmissivity evaluation was completed for all wells based on the results of the tests and subsequent gauging At two wells 51-08 and 51-19 the tests were analyzed using the BampR and CampJ

methods in the API Workbook to determine a transmissivity at the well (Table 2) Estimated transmissivity values were below the MassDEP and ITRC criterion of recoverability of 08 ft2day

Manual skimming tests were completed at 59-03R GMA3-12 and GMA-17 and analysis of the data was completed using Equation 1 (ASTM 2013) to estimate a transmissivity at each well The tests were completed in January 2017 and ranged in duration from approximately five to nine hours Periodic purging of LNAPL was performed to maintain an LNAPL thickness of less than 25 percent of the initial gauged thickness and only data that met that criteria were used in the analysis LNAPL transmissivity estimates for all three wells are below the criterion of recoverability of 08 ft2day indicating that continued hydraulic operations would not result in beneficial recovery of LNAPL from the subsurface near the wells

Where baildown test data are not suitable for analysis by the Bower amp Rice and Cooper amp Jacob method the data are analyzed using Eq 1 an estimated constant rate of NAPL discharge to the well from test data that best represents formation drainage and an average NAPL drawdown induced during that period of the test Data collected during tests conducted at wells 51-17 and 51-21 were evaluated in this manner The LNAPL transmissivity estimates 004 ft2day and 0002 ft2day respectively are both below the criterion of recoverability of 08 ft2day

4 CONCLUSIONS

Evaluation of the baildown and manual skimming tests indicate NAPL transmissivities were generally below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016) with two noted exceptions at wells N2SC-1I(R) and N2SC-03I(R) where only a small percentage of the total casing and filter pack volume was able to be removed at the start of the test likely resulting in initial filter pack drainage

Transmissivity calculations from LNAPL baildown tests LNAPL manual skimming tests and DNAPL baildown tests completed in GMA1 and GMA3 generally indicate that NAPL recovery potential at the Site from these specific systems are negligible NAPL transmissivities are below the criterion of recoverability of 08 ft2day (ITRC 2009) with the exception of well N2SC-01I and N2SC-03I(R) in GMA1 The estimated transmissivities at these two wells likely represent filter pack drainage and little if any of the longer-term potential for NAPL recoverability from the formation At N2SC-03I(R) the NAPL transmissivity estimate for only one of the three analysis methods exceeds the MassDEP and ITRC criterion Additionally tests conducted at or near wells with recovery systems in place indicate that further NAPL recovery will not provide a meaningful benefit for the Site A summary of activities conducted and conclusions reached for each area is included below

41 Conclusions for GMA1 East Street Area 1

Of the three wells proposed for testing only one well (106) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

The LNAPL transmissivity estimate for this area is 001 ft2day

42 Conclusions for GMA1 Newell Street Area II

Of the wells proposed for testing all six (N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14) met the criterion to be tested

DNAPL transmissivity estimates for this area ranged from near-zero to 28 ft2day with five of the six estimates below the 08 ft2day MassDEP and ITRC criterion The exceedance to the criteria is likely the result of initial filter pack drainage

43 Conclusions for GMA3

Of the 13 wells proposed for testing in this area only seven wells (51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

LNAPL transmissivity estimates for this area ranged from 0002 ft2day to 04 ft2day

5 RECOMMENDATIONS

Currently in-well NAPL thickness is the criteria by which NAPL recovery at a well is determined to be required In accordance with recently developed standards and guidance endorsed by ITRC ASTM and a number of state agencies including MassDEP it is recommended that NAPL transmissivity data be used to develop a riskbenefit-based approach to NAPL recovery and management at the Site NAPL transmissivity rather than measured NAPL thickness is the most appropriate indicator of the potential for NAPL recovery to provide beneficial reduction in NAPL mass Specific recommendations for changes to the recovery criteria and management program are provided below

51 Recommendations for GMA1 East Street Area 1

Operation of the LNAPL recovery systems in this area should be discontinued because recovery by hydraulic methods in this area is unlikely to beneficially reduce LNAPL in the subsurface

LNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

Fluid level gauging should continue within the well network to monitor LNAPL thickness in wells where it has historically been observed

52 Recommendations for GMA1 Newell Street Area II

Operation of the DNAPL recovery system should be discontinued because DNAPL recovery by hydraulic methods in this area is unlikely to beneficially reduce NAPL in the subsurface

Periodic DNAPL recovery by manual bailing should be continued at wells where transmissivity is found to be greater than 08 ft2day when Site-specific recovery criteria are met

DNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

GMA 1 AND 3 ndash TRANSMISSIVITY ASSESSMENT AND RECOVERY RECOMMENDATIONS

1 INTRODUCTION

Arcadis US Inc (Arcadis) has prepared this memorandum on behalf of General Electric Company (GE) at the request of the US Environmental Protection Agency (EPA) to present additional data related to both Light Non-Aqueous Phase Liquid (LNAPL) and Dense Non-Aqueous Phase Liquid (DNAPL) recoverability within portions of GErsquos Pittsfield MA site (Figure 1) In the September 30 2016 proposal to EPA entitled ldquoGE-PittsfieldHousatonic River Site (the ldquoSiterdquo) Evaluation of NAPL Recovery Systems ndash Proposed Activities Groundwater Management Areas 1 and 3rdquo GE presented an evaluation approach involving NAPL transmissivity testing including collecting evaluating and reporting additional transmissivity data to evaluate the effectiveness of automated or manual NAPL recovery for these specified areas This memorandum has been prepared to present the results of the NAPL recovery data collected between January 18 2017 and April 20 2017 and provide recommendations for program modifications

11 Background

Since the onset of NAPL recovery at the Site over 35 years ago GE has continuously monitored assessed upgraded expanded and optimized its NAPL recovery efforts Over this time there has been success in 1) removing NAPL from the Site (to varying degrees based on the recovery system) 2) reducing the overall extent and quantity of mobile NAPL that remains within the Site and 3) maintaining compliance with the applicable Performance Standards established in the October 2000 Consent Decree (CD) For certain recovery systems the NAPL recovery rates have diminished over time to the point where limited NAPL recovery is currently being realized This evaluation was performed in accordance with Technical Attachment H of Appendix E to the CD to assess recovery systems at the Site and propose enhancements or modifications as necessary to meet the long-term goal of maximizing NAPL recovery and eliminating mobile NAPL These NAPL transmissivity results are used to evaluate whether NAPL recovery via hydraulic operations remains a feasible and practical alternative for NAPL mass reduction A NAPL transmissivity of 08 square feet per day (ft2day) is used as the criterion for practical NAPL recoverability (ITRC 2009 MassDEP 2016) Below this value hydraulic recovery will not lead to remedial benefit and is not likely to substantially reduce the overall NAPL mass in the subsurface NAPL transmissivity data was collected at the Site beginning in January 2017 and included the completion of five LNAPL baildown tests six DNAPL baildown tests and three LNAPL manual skimming tests

2 METHODOLOGY

This NAPL recoverability assessment is based on NAPL transmissivity measurements Several methods were applied to estimate LNAPL transmissivity including

LNAPL baildown tests

DNAPL baildown tests

LNAPL manual skimming tests

The following sections describe the specific methodology for each of the lines of evidence used in this NAPL recoverability assessment The methodology for LNAPL transmissivity data collection and analysis

are consistent with the ASTM International (ASTM) Standard Guide for Estimation of LNAPL Transmissivity E2856-13 (ASTM 2013)

While no industry-wide standards or test methods currently exist for DNAPL baildown testing the same principles of LNAPL mobility and recoverability are appropriate to evaluate DNAPL mobility (Nelson and Smith 2016 Nelson 2017) Testing was subject to the same pre-test conditions (eg stability of NAPL thickness and no influence from an active recovery system) and testing methods (eg baildown testing) as those conducted for LNAPL assessment Also the active system operations were suspended prior to the test

3 NAPL FIELD TRANSMISSIVITY

The recoverability of NAPL is influenced by many factors including NAPL saturation in the impacted soil soil permeability and physical properties of the NAPL Transmissivity represents the volumetric rate of NAPL flow through a unit width of porous media per unit time under a unit hydraulic gradient A direct mathematical relationship exists between NAPL transmissivity and the rate of NAPL flow into a well therefore it is an ideal parameter for assessing NAPL recoverability NAPL transmissivity calculations inherently account for the combined effects of aquifer matrix permeability NAPL physical properties and the relative proportion of pore space occupied by NAPL within a specified vertical interval of aquifer material Five NAPL samples from wells representative of site conditions (51-08 51-19 106 N2SC-13I and N2SC-01I) were collected and submitted to PTS Laboratories Inc in Santa Fe Springs California for viscosity density and specific gravity analysis Results of the analysis are provided in Appendix A

31 NAPL Baildown Tests

A NAPL baildown test is initiated by quickly removing accumulated LNAPL from a well The rate of NAPL flow into the well is a function of soil and NAPL properties as well as the magnitude of the initial hydraulic gradient toward the well developed during NAPL removal The baildown test response is influenced by the prevalent fluid levels at the time of testing Baildown tests were performed in areas GMA1 (East Street Area 1 and Newell Street Area II) and GMA3 at the Site to describe the range of NAPL transmissivities under different fluid level conditions In general a minimum stable NAPL thickness of about 05 ft is necessary to perform a baildown test

Baildown tests are analyzed in the American Petroleum Institute (API) LNAPL Transmissivity Workbook API Workbook [API 2012]) and a modified API Workbook for DNAPL (Nelson and Smith 2016 Nelson 2017) using modified versions of the Bouwer and Rice (BampR) (1976) and Cooper and Jacob (CampJ) (1946)Jacob and Lohman (1952) slug test method Each of the available solutions involves different assumptions regarding the response of fluid levels within the well to the removal of NAPL Where possible baildown test data are evaluated using each of the solutions If data are not suitable for analysis using one or more of the methods only results obtained using the applicable analysis methods will be reported

Some baildown tests do not generate data that can be analyzed using the API Workbook This generally occurs when there is limited NAPL thickness at test initiation the NAPL in the well is not in equilibrium with the formation or the NAPL discharge into the well cannot be related to the NAPL drawdown induced during the test In cases where the NAPL discharge trend is difficult to identify transmissivity can be estimated

using the manual skimming evaluation method (Section 32) a constant rate of NAPL discharge to the well derived from test data and an average NAPL drawdown induced during that period of the test

Data analysis options in the API Workbook include a data time cut and drawdown adjustment that can be applied as needed A data time cut is required for nearly every test where early-time hydraulic response data representing filter pack drainage is removed from analysis Initial filter pack drainage does not represent formation drainage and an analysis incorporating these data will lead to erroneous results The drawdown adjustment is only applied if NAPL in the well at the time of test initiation is not in equilibrium with NAPL in the formation resulting in a clear trend of zero NAPL discharge at a non-zero (positive or negative) value for NAPL drawdown The drawdown adjustment is applied to reconcile the calculated drawdown with the observed trend toward zero discharge Further information on the data time cut and drawdown adjustment is provided in the user guide for the API Workbook (API 2012)

32 LNAPL Manual Skimming Tests

LNAPL manual skimming tests involve repeated LNAPL recovery periods and thus may test a larger portion of the LNAPL-impacted formation Transmissivity estimates from manual LNAPL skimming tests are expected to correlate more strongly to results that would be expected for LNAPL recovery system operation

A manual skimming test consists of removing all LNAPL from a well gauging the well as the LNAPL recharges and removing LNAPL again before the NAPL thickness reaches 25 percent of the pre-test LNAPL thickness This process is repeated until the LNAPL removal rate stabilizes In general a minimum stable LNAPL thickness of about 03 ft is necessary to perform a manual skimming test

Analysis of the manual LNAPL skimming test data can be completed using Equation 1 (ASTM 2013)

Qn = measured LNAPL recovery rate cubic feet per day (feet3day)

ROI = radius of influence feet

rw = well radius feet

sn = LNAPL drawdown feet

The radius of influence is difficult to estimate for a manual skimming test however because the term occurs within a logarithmic function in Equation 1 the value is not critical for estimating LNAPL transmissivity For this evaluation the value of the term ldquoln (ROIrw)rdquo was assumed to be 46 per ASTM guidance (ASTM 2013)

33 Field Data Collection and Evaluation

(MCP) That guidance document provides details and discussion related to the use of transmissivity testing as part of an overall demonstration of LNAPL recoverability including the feasibility of continued system operation Per the September 30 2016 proposal to EPA and consistent with state regulatory guidance LNAPL transmissivity testing and DNAPL transmissivity testing was performed at select locations within GMA 1 and GMA 3 The results of the tests are summarized below

331 GMA 1 East Street Area 1

Transmissivity testing was proposed to be completed at wells 105 106 and ESA1S-45 based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet Initial gauging prior to the event was conducted during which only one well 106 had sufficient LNAPL thickness to perform a LNAPL baildown test Wells 105 and ESA1S-45 had measurable LNAPL thicknesses of 021 and 016 feet respectively during the initial gauging event Over the course of approximately 8-weeks LNAPL thicknesses in those wells did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively (Table 1) Given the historical recovery volume (Arcadis 2017a) and small vertical interval of measurable LNAPL in each of these wells continued recovery is unlikely to produce a volume that would beneficially reduce LNAPL mass in the subsurface Field data for the LNAPL baildown test at well 106 is included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown test at 106 are included as Appendix C A summary of results is included on Table 2 and is shown on Figure 2

An LNAPL baildown test was initiated at well 106 in January 2017 Prior to the start of the test fluid level gauging and depth to bottom measurements were collected at which point an obstruction or anomaly was detected at a depth of 966 feet bgs while the well depth is typically measured as approximately 175 feet bgs This anomaly has not been observed previously and the fall 2016 and spring 2017 measurements were able to reach the bottom of the well While initial LNAPL thickness could not be determined because the obstruction was above the NAPL-water interface the depth to the NAPL-air interface (depth to LNAPL) was determined and is assumed to represent equilibrium conditions Fluid level measurements were collected periodically for approximately eight hours at the well LNAPL recharged to about 43 of initial measured thickness by the end of the first test day so periodic gauging for LNAPL thickness over the following eight weeks to evaluate further recharge was conducted While water table fluctuations were observed during this time which are expected LNAPL thickness had not returned to the initial thickness observed as of March 2017 (Table 1) Because of the limited LNAPL recharge the baildown test data were not suitable for evaluation by the standard analytical solutions Instead they were analyzed using Eq 1 and a constant rate of NAPL discharge to the well estimated from test data that likely represents formation drainage and an average NAPL drawdown induced during that period of the test This evaluation indicates a transmissivity of about 001 ft2day well below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016)

332 GMA1 Newell Street Area II

DNAPL recoverability testing was proposed to be completed at wells N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14 based on a review of historical gauging data that indicated measurable DNAPL was present at thicknesses greater than 03 feet and at a depth greater than the documented top of sump indicating a hydraulic connection at the time of the test between DNAPL present

in the wells and DNAPL in the surrounding formation Initial gauging was conducted prior to the event during which five of six wells met the thickness and formation connection criteria required to perform a baildown test at the well Baildown tests were completed in January 2017 While on-going gauging was conducted at the area wells for approximately eight weeks following the tests to assess recharge conditions in the well the portion of the tests that were able be evaluated quantitively ranged from approximately four to 28 hours Field data for the DNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for DNAPL baildown tests are included as Appendix C A summary of results is included on Tables 2 and 3 and are shown on Figure 2

Quantitative transmissivity evaluations were completed for four wells N2SC-1I N2SC-1I(R) N2SC-03I(R) and N2SC-14 based on the results of the tests and subsequent gauging At all four wells the tests were analyzed using the API Workbook to determine a transmissivity at the well At three wells a constant NAPL dischargedrawdown analysis was also conducted for a portion of the test where test data likely represents formation drainage

Well N2SC-1I Baildown test results at well N2SC-1I were analyzed using the API Workbook (both BampR and CampJ methods) resulting in estimated transmissivity values above the criterion of recoverability of 08 ft2day The average transmissivity value was 28 ft2day though during the initial purge of DNAPL from the well less than 12 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered Most if not all of the recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-1I(R) which is only several feet away and screened across a similar interval indicated transmissivity values well below the 08 ft2day criteria which is further evidence that calculated recoverability was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-1I(R) Baildown tests at well N2SC-1I(R) were analyzed using both the API Workbook and a constant NAPL dischargedrawdown analysis resulting in estimated transmissivity values below the criterion of recoverability of 08 ft2day The average transmissivity value was 01 ft2day indicating DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I DNAPL was measured in well N2SC-03I at a depth below the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I(R) Baildown test results at well N2SC-03I(R) were analyzed using the API Workbook (both BampR and CampJ methods) and through a constant NAPL dischargedrawdown analysis Transmissivities determined at the well include one value above the 08 ft2day criteria and an average transmissivity of 05 ft2day During the initial purge of DNAPL from the well less

than 25 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered The recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-03I which is only several feet away and screened across a similar interval indicated no recharge from the formation following an initial recovery which is further evidence that calculated recoverability for well N2SC-03I(R) was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-13I Following initial recovery DNAPL was not measured in well N2SC-13I at a depth above the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-14 Gauging data collected from well N2SC-14 following the removal of DNAPL in the well sump indicated measurable DNAPL was present within the well screen interval only once during the initial and subsequent gauging that was conducted periodically for eight weeks following the initiation of the test Where DNAPL recharge is gauged only in the well sump evaluation by the API Workbook is not appropriate and an estimated transmissivity may be derived by utilizing a DNAPL drawdown consistent with the stable thickness in the screened interval and a constant DNAPL discharge determined through a calculation of measured volume of recharge to the well over a given time Late time series data was used to determine DNAPL discharge and DNAPL drawdown this way resulting in a transmissivity of 03 ft2day at the well below the criterion of recoverability of 08 ft2day These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Transmissivity testing was proposed to be completed at 13 wells in the GMA3 area based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet However during the pretest gauging only wells 51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17 had sufficient LNAPL thickness to perform either a LNAPL baildown or manual skimming test Over the course of approximately 8-weeks LNAPL thicknesses in the six wells without adequate thickness did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively Field data for the LNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown tests are included as Appendix C and manual skimming test input and output data are included as Appendix D and E respectively A summary of results is included on Tables 2 and 3 and are shown on Figure 3

Quantitative transmissivity evaluation was completed for all wells based on the results of the tests and subsequent gauging At two wells 51-08 and 51-19 the tests were analyzed using the BampR and CampJ

methods in the API Workbook to determine a transmissivity at the well (Table 2) Estimated transmissivity values were below the MassDEP and ITRC criterion of recoverability of 08 ft2day

Manual skimming tests were completed at 59-03R GMA3-12 and GMA-17 and analysis of the data was completed using Equation 1 (ASTM 2013) to estimate a transmissivity at each well The tests were completed in January 2017 and ranged in duration from approximately five to nine hours Periodic purging of LNAPL was performed to maintain an LNAPL thickness of less than 25 percent of the initial gauged thickness and only data that met that criteria were used in the analysis LNAPL transmissivity estimates for all three wells are below the criterion of recoverability of 08 ft2day indicating that continued hydraulic operations would not result in beneficial recovery of LNAPL from the subsurface near the wells

Where baildown test data are not suitable for analysis by the Bower amp Rice and Cooper amp Jacob method the data are analyzed using Eq 1 an estimated constant rate of NAPL discharge to the well from test data that best represents formation drainage and an average NAPL drawdown induced during that period of the test Data collected during tests conducted at wells 51-17 and 51-21 were evaluated in this manner The LNAPL transmissivity estimates 004 ft2day and 0002 ft2day respectively are both below the criterion of recoverability of 08 ft2day

4 CONCLUSIONS

Evaluation of the baildown and manual skimming tests indicate NAPL transmissivities were generally below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016) with two noted exceptions at wells N2SC-1I(R) and N2SC-03I(R) where only a small percentage of the total casing and filter pack volume was able to be removed at the start of the test likely resulting in initial filter pack drainage

Transmissivity calculations from LNAPL baildown tests LNAPL manual skimming tests and DNAPL baildown tests completed in GMA1 and GMA3 generally indicate that NAPL recovery potential at the Site from these specific systems are negligible NAPL transmissivities are below the criterion of recoverability of 08 ft2day (ITRC 2009) with the exception of well N2SC-01I and N2SC-03I(R) in GMA1 The estimated transmissivities at these two wells likely represent filter pack drainage and little if any of the longer-term potential for NAPL recoverability from the formation At N2SC-03I(R) the NAPL transmissivity estimate for only one of the three analysis methods exceeds the MassDEP and ITRC criterion Additionally tests conducted at or near wells with recovery systems in place indicate that further NAPL recovery will not provide a meaningful benefit for the Site A summary of activities conducted and conclusions reached for each area is included below

41 Conclusions for GMA1 East Street Area 1

Of the three wells proposed for testing only one well (106) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

The LNAPL transmissivity estimate for this area is 001 ft2day

42 Conclusions for GMA1 Newell Street Area II

Of the wells proposed for testing all six (N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14) met the criterion to be tested

DNAPL transmissivity estimates for this area ranged from near-zero to 28 ft2day with five of the six estimates below the 08 ft2day MassDEP and ITRC criterion The exceedance to the criteria is likely the result of initial filter pack drainage

43 Conclusions for GMA3

Of the 13 wells proposed for testing in this area only seven wells (51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

LNAPL transmissivity estimates for this area ranged from 0002 ft2day to 04 ft2day

5 RECOMMENDATIONS

Currently in-well NAPL thickness is the criteria by which NAPL recovery at a well is determined to be required In accordance with recently developed standards and guidance endorsed by ITRC ASTM and a number of state agencies including MassDEP it is recommended that NAPL transmissivity data be used to develop a riskbenefit-based approach to NAPL recovery and management at the Site NAPL transmissivity rather than measured NAPL thickness is the most appropriate indicator of the potential for NAPL recovery to provide beneficial reduction in NAPL mass Specific recommendations for changes to the recovery criteria and management program are provided below

51 Recommendations for GMA1 East Street Area 1

Operation of the LNAPL recovery systems in this area should be discontinued because recovery by hydraulic methods in this area is unlikely to beneficially reduce LNAPL in the subsurface

LNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

Fluid level gauging should continue within the well network to monitor LNAPL thickness in wells where it has historically been observed

52 Recommendations for GMA1 Newell Street Area II

Operation of the DNAPL recovery system should be discontinued because DNAPL recovery by hydraulic methods in this area is unlikely to beneficially reduce NAPL in the subsurface

Periodic DNAPL recovery by manual bailing should be continued at wells where transmissivity is found to be greater than 08 ft2day when Site-specific recovery criteria are met

DNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

GMA 1 AND 3 ndash TRANSMISSIVITY ASSESSMENT AND RECOVERY RECOMMENDATIONS

1 INTRODUCTION

Arcadis US Inc (Arcadis) has prepared this memorandum on behalf of General Electric Company (GE) at the request of the US Environmental Protection Agency (EPA) to present additional data related to both Light Non-Aqueous Phase Liquid (LNAPL) and Dense Non-Aqueous Phase Liquid (DNAPL) recoverability within portions of GErsquos Pittsfield MA site (Figure 1) In the September 30 2016 proposal to EPA entitled ldquoGE-PittsfieldHousatonic River Site (the ldquoSiterdquo) Evaluation of NAPL Recovery Systems ndash Proposed Activities Groundwater Management Areas 1 and 3rdquo GE presented an evaluation approach involving NAPL transmissivity testing including collecting evaluating and reporting additional transmissivity data to evaluate the effectiveness of automated or manual NAPL recovery for these specified areas This memorandum has been prepared to present the results of the NAPL recovery data collected between January 18 2017 and April 20 2017 and provide recommendations for program modifications

11 Background

Since the onset of NAPL recovery at the Site over 35 years ago GE has continuously monitored assessed upgraded expanded and optimized its NAPL recovery efforts Over this time there has been success in 1) removing NAPL from the Site (to varying degrees based on the recovery system) 2) reducing the overall extent and quantity of mobile NAPL that remains within the Site and 3) maintaining compliance with the applicable Performance Standards established in the October 2000 Consent Decree (CD) For certain recovery systems the NAPL recovery rates have diminished over time to the point where limited NAPL recovery is currently being realized This evaluation was performed in accordance with Technical Attachment H of Appendix E to the CD to assess recovery systems at the Site and propose enhancements or modifications as necessary to meet the long-term goal of maximizing NAPL recovery and eliminating mobile NAPL These NAPL transmissivity results are used to evaluate whether NAPL recovery via hydraulic operations remains a feasible and practical alternative for NAPL mass reduction A NAPL transmissivity of 08 square feet per day (ft2day) is used as the criterion for practical NAPL recoverability (ITRC 2009 MassDEP 2016) Below this value hydraulic recovery will not lead to remedial benefit and is not likely to substantially reduce the overall NAPL mass in the subsurface NAPL transmissivity data was collected at the Site beginning in January 2017 and included the completion of five LNAPL baildown tests six DNAPL baildown tests and three LNAPL manual skimming tests

2 METHODOLOGY

This NAPL recoverability assessment is based on NAPL transmissivity measurements Several methods were applied to estimate LNAPL transmissivity including

LNAPL baildown tests

DNAPL baildown tests

LNAPL manual skimming tests

The following sections describe the specific methodology for each of the lines of evidence used in this NAPL recoverability assessment The methodology for LNAPL transmissivity data collection and analysis

are consistent with the ASTM International (ASTM) Standard Guide for Estimation of LNAPL Transmissivity E2856-13 (ASTM 2013)

While no industry-wide standards or test methods currently exist for DNAPL baildown testing the same principles of LNAPL mobility and recoverability are appropriate to evaluate DNAPL mobility (Nelson and Smith 2016 Nelson 2017) Testing was subject to the same pre-test conditions (eg stability of NAPL thickness and no influence from an active recovery system) and testing methods (eg baildown testing) as those conducted for LNAPL assessment Also the active system operations were suspended prior to the test

3 NAPL FIELD TRANSMISSIVITY

The recoverability of NAPL is influenced by many factors including NAPL saturation in the impacted soil soil permeability and physical properties of the NAPL Transmissivity represents the volumetric rate of NAPL flow through a unit width of porous media per unit time under a unit hydraulic gradient A direct mathematical relationship exists between NAPL transmissivity and the rate of NAPL flow into a well therefore it is an ideal parameter for assessing NAPL recoverability NAPL transmissivity calculations inherently account for the combined effects of aquifer matrix permeability NAPL physical properties and the relative proportion of pore space occupied by NAPL within a specified vertical interval of aquifer material Five NAPL samples from wells representative of site conditions (51-08 51-19 106 N2SC-13I and N2SC-01I) were collected and submitted to PTS Laboratories Inc in Santa Fe Springs California for viscosity density and specific gravity analysis Results of the analysis are provided in Appendix A

31 NAPL Baildown Tests

A NAPL baildown test is initiated by quickly removing accumulated LNAPL from a well The rate of NAPL flow into the well is a function of soil and NAPL properties as well as the magnitude of the initial hydraulic gradient toward the well developed during NAPL removal The baildown test response is influenced by the prevalent fluid levels at the time of testing Baildown tests were performed in areas GMA1 (East Street Area 1 and Newell Street Area II) and GMA3 at the Site to describe the range of NAPL transmissivities under different fluid level conditions In general a minimum stable NAPL thickness of about 05 ft is necessary to perform a baildown test

Baildown tests are analyzed in the American Petroleum Institute (API) LNAPL Transmissivity Workbook API Workbook [API 2012]) and a modified API Workbook for DNAPL (Nelson and Smith 2016 Nelson 2017) using modified versions of the Bouwer and Rice (BampR) (1976) and Cooper and Jacob (CampJ) (1946)Jacob and Lohman (1952) slug test method Each of the available solutions involves different assumptions regarding the response of fluid levels within the well to the removal of NAPL Where possible baildown test data are evaluated using each of the solutions If data are not suitable for analysis using one or more of the methods only results obtained using the applicable analysis methods will be reported

Some baildown tests do not generate data that can be analyzed using the API Workbook This generally occurs when there is limited NAPL thickness at test initiation the NAPL in the well is not in equilibrium with the formation or the NAPL discharge into the well cannot be related to the NAPL drawdown induced during the test In cases where the NAPL discharge trend is difficult to identify transmissivity can be estimated

using the manual skimming evaluation method (Section 32) a constant rate of NAPL discharge to the well derived from test data and an average NAPL drawdown induced during that period of the test

Data analysis options in the API Workbook include a data time cut and drawdown adjustment that can be applied as needed A data time cut is required for nearly every test where early-time hydraulic response data representing filter pack drainage is removed from analysis Initial filter pack drainage does not represent formation drainage and an analysis incorporating these data will lead to erroneous results The drawdown adjustment is only applied if NAPL in the well at the time of test initiation is not in equilibrium with NAPL in the formation resulting in a clear trend of zero NAPL discharge at a non-zero (positive or negative) value for NAPL drawdown The drawdown adjustment is applied to reconcile the calculated drawdown with the observed trend toward zero discharge Further information on the data time cut and drawdown adjustment is provided in the user guide for the API Workbook (API 2012)

32 LNAPL Manual Skimming Tests

LNAPL manual skimming tests involve repeated LNAPL recovery periods and thus may test a larger portion of the LNAPL-impacted formation Transmissivity estimates from manual LNAPL skimming tests are expected to correlate more strongly to results that would be expected for LNAPL recovery system operation

A manual skimming test consists of removing all LNAPL from a well gauging the well as the LNAPL recharges and removing LNAPL again before the NAPL thickness reaches 25 percent of the pre-test LNAPL thickness This process is repeated until the LNAPL removal rate stabilizes In general a minimum stable LNAPL thickness of about 03 ft is necessary to perform a manual skimming test

Analysis of the manual LNAPL skimming test data can be completed using Equation 1 (ASTM 2013)

Qn = measured LNAPL recovery rate cubic feet per day (feet3day)

ROI = radius of influence feet

rw = well radius feet

sn = LNAPL drawdown feet

The radius of influence is difficult to estimate for a manual skimming test however because the term occurs within a logarithmic function in Equation 1 the value is not critical for estimating LNAPL transmissivity For this evaluation the value of the term ldquoln (ROIrw)rdquo was assumed to be 46 per ASTM guidance (ASTM 2013)

(MCP) That guidance document provides details and discussion related to the use of transmissivity testing as part of an overall demonstration of LNAPL recoverability including the feasibility of continued system operation Per the September 30 2016 proposal to EPA and consistent with state regulatory guidance LNAPL transmissivity testing and DNAPL transmissivity testing was performed at select locations within GMA 1 and GMA 3 The results of the tests are summarized below

331 GMA 1 East Street Area 1

Transmissivity testing was proposed to be completed at wells 105 106 and ESA1S-45 based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet Initial gauging prior to the event was conducted during which only one well 106 had sufficient LNAPL thickness to perform a LNAPL baildown test Wells 105 and ESA1S-45 had measurable LNAPL thicknesses of 021 and 016 feet respectively during the initial gauging event Over the course of approximately 8-weeks LNAPL thicknesses in those wells did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively (Table 1) Given the historical recovery volume (Arcadis 2017a) and small vertical interval of measurable LNAPL in each of these wells continued recovery is unlikely to produce a volume that would beneficially reduce LNAPL mass in the subsurface Field data for the LNAPL baildown test at well 106 is included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown test at 106 are included as Appendix C A summary of results is included on Table 2 and is shown on Figure 2

An LNAPL baildown test was initiated at well 106 in January 2017 Prior to the start of the test fluid level gauging and depth to bottom measurements were collected at which point an obstruction or anomaly was detected at a depth of 966 feet bgs while the well depth is typically measured as approximately 175 feet bgs This anomaly has not been observed previously and the fall 2016 and spring 2017 measurements were able to reach the bottom of the well While initial LNAPL thickness could not be determined because the obstruction was above the NAPL-water interface the depth to the NAPL-air interface (depth to LNAPL) was determined and is assumed to represent equilibrium conditions Fluid level measurements were collected periodically for approximately eight hours at the well LNAPL recharged to about 43 of initial measured thickness by the end of the first test day so periodic gauging for LNAPL thickness over the following eight weeks to evaluate further recharge was conducted While water table fluctuations were observed during this time which are expected LNAPL thickness had not returned to the initial thickness observed as of March 2017 (Table 1) Because of the limited LNAPL recharge the baildown test data were not suitable for evaluation by the standard analytical solutions Instead they were analyzed using Eq 1 and a constant rate of NAPL discharge to the well estimated from test data that likely represents formation drainage and an average NAPL drawdown induced during that period of the test This evaluation indicates a transmissivity of about 001 ft2day well below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016)

DNAPL recoverability testing was proposed to be completed at wells N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14 based on a review of historical gauging data that indicated measurable DNAPL was present at thicknesses greater than 03 feet and at a depth greater than the documented top of sump indicating a hydraulic connection at the time of the test between DNAPL present

in the wells and DNAPL in the surrounding formation Initial gauging was conducted prior to the event during which five of six wells met the thickness and formation connection criteria required to perform a baildown test at the well Baildown tests were completed in January 2017 While on-going gauging was conducted at the area wells for approximately eight weeks following the tests to assess recharge conditions in the well the portion of the tests that were able be evaluated quantitively ranged from approximately four to 28 hours Field data for the DNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for DNAPL baildown tests are included as Appendix C A summary of results is included on Tables 2 and 3 and are shown on Figure 2

Quantitative transmissivity evaluations were completed for four wells N2SC-1I N2SC-1I(R) N2SC-03I(R) and N2SC-14 based on the results of the tests and subsequent gauging At all four wells the tests were analyzed using the API Workbook to determine a transmissivity at the well At three wells a constant NAPL dischargedrawdown analysis was also conducted for a portion of the test where test data likely represents formation drainage

Well N2SC-1I Baildown test results at well N2SC-1I were analyzed using the API Workbook (both BampR and CampJ methods) resulting in estimated transmissivity values above the criterion of recoverability of 08 ft2day The average transmissivity value was 28 ft2day though during the initial purge of DNAPL from the well less than 12 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered Most if not all of the recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-1I(R) which is only several feet away and screened across a similar interval indicated transmissivity values well below the 08 ft2day criteria which is further evidence that calculated recoverability was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-1I(R) Baildown tests at well N2SC-1I(R) were analyzed using both the API Workbook and a constant NAPL dischargedrawdown analysis resulting in estimated transmissivity values below the criterion of recoverability of 08 ft2day The average transmissivity value was 01 ft2day indicating DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I DNAPL was measured in well N2SC-03I at a depth below the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I(R) Baildown test results at well N2SC-03I(R) were analyzed using the API Workbook (both BampR and CampJ methods) and through a constant NAPL dischargedrawdown analysis Transmissivities determined at the well include one value above the 08 ft2day criteria and an average transmissivity of 05 ft2day During the initial purge of DNAPL from the well less

than 25 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered The recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-03I which is only several feet away and screened across a similar interval indicated no recharge from the formation following an initial recovery which is further evidence that calculated recoverability for well N2SC-03I(R) was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-13I Following initial recovery DNAPL was not measured in well N2SC-13I at a depth above the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-14 Gauging data collected from well N2SC-14 following the removal of DNAPL in the well sump indicated measurable DNAPL was present within the well screen interval only once during the initial and subsequent gauging that was conducted periodically for eight weeks following the initiation of the test Where DNAPL recharge is gauged only in the well sump evaluation by the API Workbook is not appropriate and an estimated transmissivity may be derived by utilizing a DNAPL drawdown consistent with the stable thickness in the screened interval and a constant DNAPL discharge determined through a calculation of measured volume of recharge to the well over a given time Late time series data was used to determine DNAPL discharge and DNAPL drawdown this way resulting in a transmissivity of 03 ft2day at the well below the criterion of recoverability of 08 ft2day These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

333 GMA3

Transmissivity testing was proposed to be completed at 13 wells in the GMA3 area based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet However during the pretest gauging only wells 51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17 had sufficient LNAPL thickness to perform either a LNAPL baildown or manual skimming test Over the course of approximately 8-weeks LNAPL thicknesses in the six wells without adequate thickness did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively Field data for the LNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown tests are included as Appendix C and manual skimming test input and output data are included as Appendix D and E respectively A summary of results is included on Tables 2 and 3 and are shown on Figure 3

Quantitative transmissivity evaluation was completed for all wells based on the results of the tests and subsequent gauging At two wells 51-08 and 51-19 the tests were analyzed using the BampR and CampJ

methods in the API Workbook to determine a transmissivity at the well (Table 2) Estimated transmissivity values were below the MassDEP and ITRC criterion of recoverability of 08 ft2day

Manual skimming tests were completed at 59-03R GMA3-12 and GMA-17 and analysis of the data was completed using Equation 1 (ASTM 2013) to estimate a transmissivity at each well The tests were completed in January 2017 and ranged in duration from approximately five to nine hours Periodic purging of LNAPL was performed to maintain an LNAPL thickness of less than 25 percent of the initial gauged thickness and only data that met that criteria were used in the analysis LNAPL transmissivity estimates for all three wells are below the criterion of recoverability of 08 ft2day indicating that continued hydraulic operations would not result in beneficial recovery of LNAPL from the subsurface near the wells

Where baildown test data are not suitable for analysis by the Bower amp Rice and Cooper amp Jacob method the data are analyzed using Eq 1 an estimated constant rate of NAPL discharge to the well from test data that best represents formation drainage and an average NAPL drawdown induced during that period of the test Data collected during tests conducted at wells 51-17 and 51-21 were evaluated in this manner The LNAPL transmissivity estimates 004 ft2day and 0002 ft2day respectively are both below the criterion of recoverability of 08 ft2day

4 CONCLUSIONS

Evaluation of the baildown and manual skimming tests indicate NAPL transmissivities were generally below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016) with two noted exceptions at wells N2SC-1I(R) and N2SC-03I(R) where only a small percentage of the total casing and filter pack volume was able to be removed at the start of the test likely resulting in initial filter pack drainage

Transmissivity calculations from LNAPL baildown tests LNAPL manual skimming tests and DNAPL baildown tests completed in GMA1 and GMA3 generally indicate that NAPL recovery potential at the Site from these specific systems are negligible NAPL transmissivities are below the criterion of recoverability of 08 ft2day (ITRC 2009) with the exception of well N2SC-01I and N2SC-03I(R) in GMA1 The estimated transmissivities at these two wells likely represent filter pack drainage and little if any of the longer-term potential for NAPL recoverability from the formation At N2SC-03I(R) the NAPL transmissivity estimate for only one of the three analysis methods exceeds the MassDEP and ITRC criterion Additionally tests conducted at or near wells with recovery systems in place indicate that further NAPL recovery will not provide a meaningful benefit for the Site A summary of activities conducted and conclusions reached for each area is included below

41 Conclusions for GMA1 East Street Area 1

Of the three wells proposed for testing only one well (106) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

The LNAPL transmissivity estimate for this area is 001 ft2day

42 Conclusions for GMA1 Newell Street Area II

Of the wells proposed for testing all six (N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14) met the criterion to be tested

DNAPL transmissivity estimates for this area ranged from near-zero to 28 ft2day with five of the six estimates below the 08 ft2day MassDEP and ITRC criterion The exceedance to the criteria is likely the result of initial filter pack drainage

43 Conclusions for GMA3

Of the 13 wells proposed for testing in this area only seven wells (51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

LNAPL transmissivity estimates for this area ranged from 0002 ft2day to 04 ft2day

5 RECOMMENDATIONS

Currently in-well NAPL thickness is the criteria by which NAPL recovery at a well is determined to be required In accordance with recently developed standards and guidance endorsed by ITRC ASTM and a number of state agencies including MassDEP it is recommended that NAPL transmissivity data be used to develop a riskbenefit-based approach to NAPL recovery and management at the Site NAPL transmissivity rather than measured NAPL thickness is the most appropriate indicator of the potential for NAPL recovery to provide beneficial reduction in NAPL mass Specific recommendations for changes to the recovery criteria and management program are provided below

51 Recommendations for GMA1 East Street Area 1

Operation of the LNAPL recovery systems in this area should be discontinued because recovery by hydraulic methods in this area is unlikely to beneficially reduce LNAPL in the subsurface

LNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

Fluid level gauging should continue within the well network to monitor LNAPL thickness in wells where it has historically been observed

52 Recommendations for GMA1 Newell Street Area II

Operation of the DNAPL recovery system should be discontinued because DNAPL recovery by hydraulic methods in this area is unlikely to beneficially reduce NAPL in the subsurface

Periodic DNAPL recovery by manual bailing should be continued at wells where transmissivity is found to be greater than 08 ft2day when Site-specific recovery criteria are met

DNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

are consistent with the ASTM International (ASTM) Standard Guide for Estimation of LNAPL Transmissivity E2856-13 (ASTM 2013)

While no industry-wide standards or test methods currently exist for DNAPL baildown testing the same principles of LNAPL mobility and recoverability are appropriate to evaluate DNAPL mobility (Nelson and Smith 2016 Nelson 2017) Testing was subject to the same pre-test conditions (eg stability of NAPL thickness and no influence from an active recovery system) and testing methods (eg baildown testing) as those conducted for LNAPL assessment Also the active system operations were suspended prior to the test

3 NAPL FIELD TRANSMISSIVITY

The recoverability of NAPL is influenced by many factors including NAPL saturation in the impacted soil soil permeability and physical properties of the NAPL Transmissivity represents the volumetric rate of NAPL flow through a unit width of porous media per unit time under a unit hydraulic gradient A direct mathematical relationship exists between NAPL transmissivity and the rate of NAPL flow into a well therefore it is an ideal parameter for assessing NAPL recoverability NAPL transmissivity calculations inherently account for the combined effects of aquifer matrix permeability NAPL physical properties and the relative proportion of pore space occupied by NAPL within a specified vertical interval of aquifer material Five NAPL samples from wells representative of site conditions (51-08 51-19 106 N2SC-13I and N2SC-01I) were collected and submitted to PTS Laboratories Inc in Santa Fe Springs California for viscosity density and specific gravity analysis Results of the analysis are provided in Appendix A

31 NAPL Baildown Tests

A NAPL baildown test is initiated by quickly removing accumulated LNAPL from a well The rate of NAPL flow into the well is a function of soil and NAPL properties as well as the magnitude of the initial hydraulic gradient toward the well developed during NAPL removal The baildown test response is influenced by the prevalent fluid levels at the time of testing Baildown tests were performed in areas GMA1 (East Street Area 1 and Newell Street Area II) and GMA3 at the Site to describe the range of NAPL transmissivities under different fluid level conditions In general a minimum stable NAPL thickness of about 05 ft is necessary to perform a baildown test

Baildown tests are analyzed in the American Petroleum Institute (API) LNAPL Transmissivity Workbook API Workbook [API 2012]) and a modified API Workbook for DNAPL (Nelson and Smith 2016 Nelson 2017) using modified versions of the Bouwer and Rice (BampR) (1976) and Cooper and Jacob (CampJ) (1946)Jacob and Lohman (1952) slug test method Each of the available solutions involves different assumptions regarding the response of fluid levels within the well to the removal of NAPL Where possible baildown test data are evaluated using each of the solutions If data are not suitable for analysis using one or more of the methods only results obtained using the applicable analysis methods will be reported

Some baildown tests do not generate data that can be analyzed using the API Workbook This generally occurs when there is limited NAPL thickness at test initiation the NAPL in the well is not in equilibrium with the formation or the NAPL discharge into the well cannot be related to the NAPL drawdown induced during the test In cases where the NAPL discharge trend is difficult to identify transmissivity can be estimated

using the manual skimming evaluation method (Section 32) a constant rate of NAPL discharge to the well derived from test data and an average NAPL drawdown induced during that period of the test

Data analysis options in the API Workbook include a data time cut and drawdown adjustment that can be applied as needed A data time cut is required for nearly every test where early-time hydraulic response data representing filter pack drainage is removed from analysis Initial filter pack drainage does not represent formation drainage and an analysis incorporating these data will lead to erroneous results The drawdown adjustment is only applied if NAPL in the well at the time of test initiation is not in equilibrium with NAPL in the formation resulting in a clear trend of zero NAPL discharge at a non-zero (positive or negative) value for NAPL drawdown The drawdown adjustment is applied to reconcile the calculated drawdown with the observed trend toward zero discharge Further information on the data time cut and drawdown adjustment is provided in the user guide for the API Workbook (API 2012)

32 LNAPL Manual Skimming Tests

LNAPL manual skimming tests involve repeated LNAPL recovery periods and thus may test a larger portion of the LNAPL-impacted formation Transmissivity estimates from manual LNAPL skimming tests are expected to correlate more strongly to results that would be expected for LNAPL recovery system operation

A manual skimming test consists of removing all LNAPL from a well gauging the well as the LNAPL recharges and removing LNAPL again before the NAPL thickness reaches 25 percent of the pre-test LNAPL thickness This process is repeated until the LNAPL removal rate stabilizes In general a minimum stable LNAPL thickness of about 03 ft is necessary to perform a manual skimming test

Analysis of the manual LNAPL skimming test data can be completed using Equation 1 (ASTM 2013)

Qn = measured LNAPL recovery rate cubic feet per day (feet3day)

ROI = radius of influence feet

rw = well radius feet

sn = LNAPL drawdown feet

The radius of influence is difficult to estimate for a manual skimming test however because the term occurs within a logarithmic function in Equation 1 the value is not critical for estimating LNAPL transmissivity For this evaluation the value of the term ldquoln (ROIrw)rdquo was assumed to be 46 per ASTM guidance (ASTM 2013)

(MCP) That guidance document provides details and discussion related to the use of transmissivity testing as part of an overall demonstration of LNAPL recoverability including the feasibility of continued system operation Per the September 30 2016 proposal to EPA and consistent with state regulatory guidance LNAPL transmissivity testing and DNAPL transmissivity testing was performed at select locations within GMA 1 and GMA 3 The results of the tests are summarized below

331 GMA 1 East Street Area 1

Transmissivity testing was proposed to be completed at wells 105 106 and ESA1S-45 based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet Initial gauging prior to the event was conducted during which only one well 106 had sufficient LNAPL thickness to perform a LNAPL baildown test Wells 105 and ESA1S-45 had measurable LNAPL thicknesses of 021 and 016 feet respectively during the initial gauging event Over the course of approximately 8-weeks LNAPL thicknesses in those wells did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively (Table 1) Given the historical recovery volume (Arcadis 2017a) and small vertical interval of measurable LNAPL in each of these wells continued recovery is unlikely to produce a volume that would beneficially reduce LNAPL mass in the subsurface Field data for the LNAPL baildown test at well 106 is included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown test at 106 are included as Appendix C A summary of results is included on Table 2 and is shown on Figure 2

An LNAPL baildown test was initiated at well 106 in January 2017 Prior to the start of the test fluid level gauging and depth to bottom measurements were collected at which point an obstruction or anomaly was detected at a depth of 966 feet bgs while the well depth is typically measured as approximately 175 feet bgs This anomaly has not been observed previously and the fall 2016 and spring 2017 measurements were able to reach the bottom of the well While initial LNAPL thickness could not be determined because the obstruction was above the NAPL-water interface the depth to the NAPL-air interface (depth to LNAPL) was determined and is assumed to represent equilibrium conditions Fluid level measurements were collected periodically for approximately eight hours at the well LNAPL recharged to about 43 of initial measured thickness by the end of the first test day so periodic gauging for LNAPL thickness over the following eight weeks to evaluate further recharge was conducted While water table fluctuations were observed during this time which are expected LNAPL thickness had not returned to the initial thickness observed as of March 2017 (Table 1) Because of the limited LNAPL recharge the baildown test data were not suitable for evaluation by the standard analytical solutions Instead they were analyzed using Eq 1 and a constant rate of NAPL discharge to the well estimated from test data that likely represents formation drainage and an average NAPL drawdown induced during that period of the test This evaluation indicates a transmissivity of about 001 ft2day well below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016)

DNAPL recoverability testing was proposed to be completed at wells N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14 based on a review of historical gauging data that indicated measurable DNAPL was present at thicknesses greater than 03 feet and at a depth greater than the documented top of sump indicating a hydraulic connection at the time of the test between DNAPL present

in the wells and DNAPL in the surrounding formation Initial gauging was conducted prior to the event during which five of six wells met the thickness and formation connection criteria required to perform a baildown test at the well Baildown tests were completed in January 2017 While on-going gauging was conducted at the area wells for approximately eight weeks following the tests to assess recharge conditions in the well the portion of the tests that were able be evaluated quantitively ranged from approximately four to 28 hours Field data for the DNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for DNAPL baildown tests are included as Appendix C A summary of results is included on Tables 2 and 3 and are shown on Figure 2

Quantitative transmissivity evaluations were completed for four wells N2SC-1I N2SC-1I(R) N2SC-03I(R) and N2SC-14 based on the results of the tests and subsequent gauging At all four wells the tests were analyzed using the API Workbook to determine a transmissivity at the well At three wells a constant NAPL dischargedrawdown analysis was also conducted for a portion of the test where test data likely represents formation drainage

Well N2SC-1I Baildown test results at well N2SC-1I were analyzed using the API Workbook (both BampR and CampJ methods) resulting in estimated transmissivity values above the criterion of recoverability of 08 ft2day The average transmissivity value was 28 ft2day though during the initial purge of DNAPL from the well less than 12 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered Most if not all of the recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-1I(R) which is only several feet away and screened across a similar interval indicated transmissivity values well below the 08 ft2day criteria which is further evidence that calculated recoverability was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-1I(R) Baildown tests at well N2SC-1I(R) were analyzed using both the API Workbook and a constant NAPL dischargedrawdown analysis resulting in estimated transmissivity values below the criterion of recoverability of 08 ft2day The average transmissivity value was 01 ft2day indicating DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I DNAPL was measured in well N2SC-03I at a depth below the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I(R) Baildown test results at well N2SC-03I(R) were analyzed using the API Workbook (both BampR and CampJ methods) and through a constant NAPL dischargedrawdown analysis Transmissivities determined at the well include one value above the 08 ft2day criteria and an average transmissivity of 05 ft2day During the initial purge of DNAPL from the well less

than 25 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered The recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-03I which is only several feet away and screened across a similar interval indicated no recharge from the formation following an initial recovery which is further evidence that calculated recoverability for well N2SC-03I(R) was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-13I Following initial recovery DNAPL was not measured in well N2SC-13I at a depth above the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-14 Gauging data collected from well N2SC-14 following the removal of DNAPL in the well sump indicated measurable DNAPL was present within the well screen interval only once during the initial and subsequent gauging that was conducted periodically for eight weeks following the initiation of the test Where DNAPL recharge is gauged only in the well sump evaluation by the API Workbook is not appropriate and an estimated transmissivity may be derived by utilizing a DNAPL drawdown consistent with the stable thickness in the screened interval and a constant DNAPL discharge determined through a calculation of measured volume of recharge to the well over a given time Late time series data was used to determine DNAPL discharge and DNAPL drawdown this way resulting in a transmissivity of 03 ft2day at the well below the criterion of recoverability of 08 ft2day These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

333 GMA3

Transmissivity testing was proposed to be completed at 13 wells in the GMA3 area based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet However during the pretest gauging only wells 51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17 had sufficient LNAPL thickness to perform either a LNAPL baildown or manual skimming test Over the course of approximately 8-weeks LNAPL thicknesses in the six wells without adequate thickness did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively Field data for the LNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown tests are included as Appendix C and manual skimming test input and output data are included as Appendix D and E respectively A summary of results is included on Tables 2 and 3 and are shown on Figure 3

Quantitative transmissivity evaluation was completed for all wells based on the results of the tests and subsequent gauging At two wells 51-08 and 51-19 the tests were analyzed using the BampR and CampJ

methods in the API Workbook to determine a transmissivity at the well (Table 2) Estimated transmissivity values were below the MassDEP and ITRC criterion of recoverability of 08 ft2day

Manual skimming tests were completed at 59-03R GMA3-12 and GMA-17 and analysis of the data was completed using Equation 1 (ASTM 2013) to estimate a transmissivity at each well The tests were completed in January 2017 and ranged in duration from approximately five to nine hours Periodic purging of LNAPL was performed to maintain an LNAPL thickness of less than 25 percent of the initial gauged thickness and only data that met that criteria were used in the analysis LNAPL transmissivity estimates for all three wells are below the criterion of recoverability of 08 ft2day indicating that continued hydraulic operations would not result in beneficial recovery of LNAPL from the subsurface near the wells

Where baildown test data are not suitable for analysis by the Bower amp Rice and Cooper amp Jacob method the data are analyzed using Eq 1 an estimated constant rate of NAPL discharge to the well from test data that best represents formation drainage and an average NAPL drawdown induced during that period of the test Data collected during tests conducted at wells 51-17 and 51-21 were evaluated in this manner The LNAPL transmissivity estimates 004 ft2day and 0002 ft2day respectively are both below the criterion of recoverability of 08 ft2day

4 CONCLUSIONS

Evaluation of the baildown and manual skimming tests indicate NAPL transmissivities were generally below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016) with two noted exceptions at wells N2SC-1I(R) and N2SC-03I(R) where only a small percentage of the total casing and filter pack volume was able to be removed at the start of the test likely resulting in initial filter pack drainage

Transmissivity calculations from LNAPL baildown tests LNAPL manual skimming tests and DNAPL baildown tests completed in GMA1 and GMA3 generally indicate that NAPL recovery potential at the Site from these specific systems are negligible NAPL transmissivities are below the criterion of recoverability of 08 ft2day (ITRC 2009) with the exception of well N2SC-01I and N2SC-03I(R) in GMA1 The estimated transmissivities at these two wells likely represent filter pack drainage and little if any of the longer-term potential for NAPL recoverability from the formation At N2SC-03I(R) the NAPL transmissivity estimate for only one of the three analysis methods exceeds the MassDEP and ITRC criterion Additionally tests conducted at or near wells with recovery systems in place indicate that further NAPL recovery will not provide a meaningful benefit for the Site A summary of activities conducted and conclusions reached for each area is included below

41 Conclusions for GMA1 East Street Area 1

Of the three wells proposed for testing only one well (106) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

The LNAPL transmissivity estimate for this area is 001 ft2day

42 Conclusions for GMA1 Newell Street Area II

Of the wells proposed for testing all six (N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14) met the criterion to be tested

DNAPL transmissivity estimates for this area ranged from near-zero to 28 ft2day with five of the six estimates below the 08 ft2day MassDEP and ITRC criterion The exceedance to the criteria is likely the result of initial filter pack drainage

43 Conclusions for GMA3

Of the 13 wells proposed for testing in this area only seven wells (51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

LNAPL transmissivity estimates for this area ranged from 0002 ft2day to 04 ft2day

5 RECOMMENDATIONS

Currently in-well NAPL thickness is the criteria by which NAPL recovery at a well is determined to be required In accordance with recently developed standards and guidance endorsed by ITRC ASTM and a number of state agencies including MassDEP it is recommended that NAPL transmissivity data be used to develop a riskbenefit-based approach to NAPL recovery and management at the Site NAPL transmissivity rather than measured NAPL thickness is the most appropriate indicator of the potential for NAPL recovery to provide beneficial reduction in NAPL mass Specific recommendations for changes to the recovery criteria and management program are provided below

51 Recommendations for GMA1 East Street Area 1

Operation of the LNAPL recovery systems in this area should be discontinued because recovery by hydraulic methods in this area is unlikely to beneficially reduce LNAPL in the subsurface

LNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

Fluid level gauging should continue within the well network to monitor LNAPL thickness in wells where it has historically been observed

52 Recommendations for GMA1 Newell Street Area II

Operation of the DNAPL recovery system should be discontinued because DNAPL recovery by hydraulic methods in this area is unlikely to beneficially reduce NAPL in the subsurface

Periodic DNAPL recovery by manual bailing should be continued at wells where transmissivity is found to be greater than 08 ft2day when Site-specific recovery criteria are met

DNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

GMA 1 AND 3 ndash TRANSMISSIVITY ASSESSMENT AND RECOVERY RECOMMENDATIONS

using the manual skimming evaluation method (Section 32) a constant rate of NAPL discharge to the well derived from test data and an average NAPL drawdown induced during that period of the test

Data analysis options in the API Workbook include a data time cut and drawdown adjustment that can be applied as needed A data time cut is required for nearly every test where early-time hydraulic response data representing filter pack drainage is removed from analysis Initial filter pack drainage does not represent formation drainage and an analysis incorporating these data will lead to erroneous results The drawdown adjustment is only applied if NAPL in the well at the time of test initiation is not in equilibrium with NAPL in the formation resulting in a clear trend of zero NAPL discharge at a non-zero (positive or negative) value for NAPL drawdown The drawdown adjustment is applied to reconcile the calculated drawdown with the observed trend toward zero discharge Further information on the data time cut and drawdown adjustment is provided in the user guide for the API Workbook (API 2012)

32 LNAPL Manual Skimming Tests

LNAPL manual skimming tests involve repeated LNAPL recovery periods and thus may test a larger portion of the LNAPL-impacted formation Transmissivity estimates from manual LNAPL skimming tests are expected to correlate more strongly to results that would be expected for LNAPL recovery system operation

A manual skimming test consists of removing all LNAPL from a well gauging the well as the LNAPL recharges and removing LNAPL again before the NAPL thickness reaches 25 percent of the pre-test LNAPL thickness This process is repeated until the LNAPL removal rate stabilizes In general a minimum stable LNAPL thickness of about 03 ft is necessary to perform a manual skimming test

Analysis of the manual LNAPL skimming test data can be completed using Equation 1 (ASTM 2013)

ln

R w

OI r T Q Equation 1

2

Qn = measured LNAPL recovery rate cubic feet per day (feet3day)

ROI = radius of influence feet

rw = well radius feet

sn = LNAPL drawdown feet

The radius of influence is difficult to estimate for a manual skimming test however because the term occurs within a logarithmic function in Equation 1 the value is not critical for estimating LNAPL transmissivity For this evaluation the value of the term ldquoln (ROIrw)rdquo was assumed to be 46 per ASTM guidance (ASTM 2013)

33 Field Data Collection and Evaluation

The Massachusetts Department of Environmental Protection (MassDEP) has prepared a document entitled ldquoLight Non-Aqueous Phase Liquids (LNAPL) and the MCP Guidance for Site Assessment and Closurerdquo (MassDEP LNAPL Guidance) for consideration at sites regulated by the Massachusetts Contingency Plan

(MCP) That guidance document provides details and discussion related to the use of transmissivity testing as part of an overall demonstration of LNAPL recoverability including the feasibility of continued system operation Per the September 30 2016 proposal to EPA and consistent with state regulatory guidance LNAPL transmissivity testing and DNAPL transmissivity testing was performed at select locations within GMA 1 and GMA 3 The results of the tests are summarized below

331 GMA 1 East Street Area 1

Transmissivity testing was proposed to be completed at wells 105 106 and ESA1S-45 based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet Initial gauging prior to the event was conducted during which only one well 106 had sufficient LNAPL thickness to perform a LNAPL baildown test Wells 105 and ESA1S-45 had measurable LNAPL thicknesses of 021 and 016 feet respectively during the initial gauging event Over the course of approximately 8-weeks LNAPL thicknesses in those wells did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively (Table 1) Given the historical recovery volume (Arcadis 2017a) and small vertical interval of measurable LNAPL in each of these wells continued recovery is unlikely to produce a volume that would beneficially reduce LNAPL mass in the subsurface Field data for the LNAPL baildown test at well 106 is included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown test at 106 are included as Appendix C A summary of results is included on Table 2 and is shown on Figure 2

An LNAPL baildown test was initiated at well 106 in January 2017 Prior to the start of the test fluid level gauging and depth to bottom measurements were collected at which point an obstruction or anomaly was detected at a depth of 966 feet bgs while the well depth is typically measured as approximately 175 feet bgs This anomaly has not been observed previously and the fall 2016 and spring 2017 measurements were able to reach the bottom of the well While initial LNAPL thickness could not be determined because the obstruction was above the NAPL-water interface the depth to the NAPL-air interface (depth to LNAPL) was determined and is assumed to represent equilibrium conditions Fluid level measurements were collected periodically for approximately eight hours at the well LNAPL recharged to about 43 of initial measured thickness by the end of the first test day so periodic gauging for LNAPL thickness over the following eight weeks to evaluate further recharge was conducted While water table fluctuations were observed during this time which are expected LNAPL thickness had not returned to the initial thickness observed as of March 2017 (Table 1) Because of the limited LNAPL recharge the baildown test data were not suitable for evaluation by the standard analytical solutions Instead they were analyzed using Eq 1 and a constant rate of NAPL discharge to the well estimated from test data that likely represents formation drainage and an average NAPL drawdown induced during that period of the test This evaluation indicates a transmissivity of about 001 ft2day well below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016)

DNAPL recoverability testing was proposed to be completed at wells N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14 based on a review of historical gauging data that indicated measurable DNAPL was present at thicknesses greater than 03 feet and at a depth greater than the documented top of sump indicating a hydraulic connection at the time of the test between DNAPL present

in the wells and DNAPL in the surrounding formation Initial gauging was conducted prior to the event during which five of six wells met the thickness and formation connection criteria required to perform a baildown test at the well Baildown tests were completed in January 2017 While on-going gauging was conducted at the area wells for approximately eight weeks following the tests to assess recharge conditions in the well the portion of the tests that were able be evaluated quantitively ranged from approximately four to 28 hours Field data for the DNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for DNAPL baildown tests are included as Appendix C A summary of results is included on Tables 2 and 3 and are shown on Figure 2

Quantitative transmissivity evaluations were completed for four wells N2SC-1I N2SC-1I(R) N2SC-03I(R) and N2SC-14 based on the results of the tests and subsequent gauging At all four wells the tests were analyzed using the API Workbook to determine a transmissivity at the well At three wells a constant NAPL dischargedrawdown analysis was also conducted for a portion of the test where test data likely represents formation drainage

Well N2SC-1I Baildown test results at well N2SC-1I were analyzed using the API Workbook (both BampR and CampJ methods) resulting in estimated transmissivity values above the criterion of recoverability of 08 ft2day The average transmissivity value was 28 ft2day though during the initial purge of DNAPL from the well less than 12 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered Most if not all of the recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-1I(R) which is only several feet away and screened across a similar interval indicated transmissivity values well below the 08 ft2day criteria which is further evidence that calculated recoverability was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-1I(R) Baildown tests at well N2SC-1I(R) were analyzed using both the API Workbook and a constant NAPL dischargedrawdown analysis resulting in estimated transmissivity values below the criterion of recoverability of 08 ft2day The average transmissivity value was 01 ft2day indicating DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I DNAPL was measured in well N2SC-03I at a depth below the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I(R) Baildown test results at well N2SC-03I(R) were analyzed using the API Workbook (both BampR and CampJ methods) and through a constant NAPL dischargedrawdown analysis Transmissivities determined at the well include one value above the 08 ft2day criteria and an average transmissivity of 05 ft2day During the initial purge of DNAPL from the well less

than 25 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered The recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-03I which is only several feet away and screened across a similar interval indicated no recharge from the formation following an initial recovery which is further evidence that calculated recoverability for well N2SC-03I(R) was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-13I Following initial recovery DNAPL was not measured in well N2SC-13I at a depth above the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-14 Gauging data collected from well N2SC-14 following the removal of DNAPL in the well sump indicated measurable DNAPL was present within the well screen interval only once during the initial and subsequent gauging that was conducted periodically for eight weeks following the initiation of the test Where DNAPL recharge is gauged only in the well sump evaluation by the API Workbook is not appropriate and an estimated transmissivity may be derived by utilizing a DNAPL drawdown consistent with the stable thickness in the screened interval and a constant DNAPL discharge determined through a calculation of measured volume of recharge to the well over a given time Late time series data was used to determine DNAPL discharge and DNAPL drawdown this way resulting in a transmissivity of 03 ft2day at the well below the criterion of recoverability of 08 ft2day These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Transmissivity testing was proposed to be completed at 13 wells in the GMA3 area based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet However during the pretest gauging only wells 51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17 had sufficient LNAPL thickness to perform either a LNAPL baildown or manual skimming test Over the course of approximately 8-weeks LNAPL thicknesses in the six wells without adequate thickness did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively Field data for the LNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown tests are included as Appendix C and manual skimming test input and output data are included as Appendix D and E respectively A summary of results is included on Tables 2 and 3 and are shown on Figure 3

Quantitative transmissivity evaluation was completed for all wells based on the results of the tests and subsequent gauging At two wells 51-08 and 51-19 the tests were analyzed using the BampR and CampJ

methods in the API Workbook to determine a transmissivity at the well (Table 2) Estimated transmissivity values were below the MassDEP and ITRC criterion of recoverability of 08 ft2day

Manual skimming tests were completed at 59-03R GMA3-12 and GMA-17 and analysis of the data was completed using Equation 1 (ASTM 2013) to estimate a transmissivity at each well The tests were completed in January 2017 and ranged in duration from approximately five to nine hours Periodic purging of LNAPL was performed to maintain an LNAPL thickness of less than 25 percent of the initial gauged thickness and only data that met that criteria were used in the analysis LNAPL transmissivity estimates for all three wells are below the criterion of recoverability of 08 ft2day indicating that continued hydraulic operations would not result in beneficial recovery of LNAPL from the subsurface near the wells

Where baildown test data are not suitable for analysis by the Bower amp Rice and Cooper amp Jacob method the data are analyzed using Eq 1 an estimated constant rate of NAPL discharge to the well from test data that best represents formation drainage and an average NAPL drawdown induced during that period of the test Data collected during tests conducted at wells 51-17 and 51-21 were evaluated in this manner The LNAPL transmissivity estimates 004 ft2day and 0002 ft2day respectively are both below the criterion of recoverability of 08 ft2day

4 CONCLUSIONS

Evaluation of the baildown and manual skimming tests indicate NAPL transmissivities were generally below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016) with two noted exceptions at wells N2SC-1I(R) and N2SC-03I(R) where only a small percentage of the total casing and filter pack volume was able to be removed at the start of the test likely resulting in initial filter pack drainage

Transmissivity calculations from LNAPL baildown tests LNAPL manual skimming tests and DNAPL baildown tests completed in GMA1 and GMA3 generally indicate that NAPL recovery potential at the Site from these specific systems are negligible NAPL transmissivities are below the criterion of recoverability of 08 ft2day (ITRC 2009) with the exception of well N2SC-01I and N2SC-03I(R) in GMA1 The estimated transmissivities at these two wells likely represent filter pack drainage and little if any of the longer-term potential for NAPL recoverability from the formation At N2SC-03I(R) the NAPL transmissivity estimate for only one of the three analysis methods exceeds the MassDEP and ITRC criterion Additionally tests conducted at or near wells with recovery systems in place indicate that further NAPL recovery will not provide a meaningful benefit for the Site A summary of activities conducted and conclusions reached for each area is included below

41 Conclusions for GMA1 East Street Area 1

Of the three wells proposed for testing only one well (106) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

The LNAPL transmissivity estimate for this area is 001 ft2day

42 Conclusions for GMA1 Newell Street Area II

Of the wells proposed for testing all six (N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14) met the criterion to be tested

DNAPL transmissivity estimates for this area ranged from near-zero to 28 ft2day with five of the six estimates below the 08 ft2day MassDEP and ITRC criterion The exceedance to the criteria is likely the result of initial filter pack drainage

43 Conclusions for GMA3

Of the 13 wells proposed for testing in this area only seven wells (51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

LNAPL transmissivity estimates for this area ranged from 0002 ft2day to 04 ft2day

5 RECOMMENDATIONS

Currently in-well NAPL thickness is the criteria by which NAPL recovery at a well is determined to be required In accordance with recently developed standards and guidance endorsed by ITRC ASTM and a number of state agencies including MassDEP it is recommended that NAPL transmissivity data be used to develop a riskbenefit-based approach to NAPL recovery and management at the Site NAPL transmissivity rather than measured NAPL thickness is the most appropriate indicator of the potential for NAPL recovery to provide beneficial reduction in NAPL mass Specific recommendations for changes to the recovery criteria and management program are provided below

51 Recommendations for GMA1 East Street Area 1

Operation of the LNAPL recovery systems in this area should be discontinued because recovery by hydraulic methods in this area is unlikely to beneficially reduce LNAPL in the subsurface

LNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

Fluid level gauging should continue within the well network to monitor LNAPL thickness in wells where it has historically been observed

52 Recommendations for GMA1 Newell Street Area II

Operation of the DNAPL recovery system should be discontinued because DNAPL recovery by hydraulic methods in this area is unlikely to beneficially reduce NAPL in the subsurface

Periodic DNAPL recovery by manual bailing should be continued at wells where transmissivity is found to be greater than 08 ft2day when Site-specific recovery criteria are met

DNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

(MCP) That guidance document provides details and discussion related to the use of transmissivity testing as part of an overall demonstration of LNAPL recoverability including the feasibility of continued system operation Per the September 30 2016 proposal to EPA and consistent with state regulatory guidance LNAPL transmissivity testing and DNAPL transmissivity testing was performed at select locations within GMA 1 and GMA 3 The results of the tests are summarized below

331 GMA 1 East Street Area 1

Transmissivity testing was proposed to be completed at wells 105 106 and ESA1S-45 based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet Initial gauging prior to the event was conducted during which only one well 106 had sufficient LNAPL thickness to perform a LNAPL baildown test Wells 105 and ESA1S-45 had measurable LNAPL thicknesses of 021 and 016 feet respectively during the initial gauging event Over the course of approximately 8-weeks LNAPL thicknesses in those wells did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively (Table 1) Given the historical recovery volume (Arcadis 2017a) and small vertical interval of measurable LNAPL in each of these wells continued recovery is unlikely to produce a volume that would beneficially reduce LNAPL mass in the subsurface Field data for the LNAPL baildown test at well 106 is included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown test at 106 are included as Appendix C A summary of results is included on Table 2 and is shown on Figure 2

An LNAPL baildown test was initiated at well 106 in January 2017 Prior to the start of the test fluid level gauging and depth to bottom measurements were collected at which point an obstruction or anomaly was detected at a depth of 966 feet bgs while the well depth is typically measured as approximately 175 feet bgs This anomaly has not been observed previously and the fall 2016 and spring 2017 measurements were able to reach the bottom of the well While initial LNAPL thickness could not be determined because the obstruction was above the NAPL-water interface the depth to the NAPL-air interface (depth to LNAPL) was determined and is assumed to represent equilibrium conditions Fluid level measurements were collected periodically for approximately eight hours at the well LNAPL recharged to about 43 of initial measured thickness by the end of the first test day so periodic gauging for LNAPL thickness over the following eight weeks to evaluate further recharge was conducted While water table fluctuations were observed during this time which are expected LNAPL thickness had not returned to the initial thickness observed as of March 2017 (Table 1) Because of the limited LNAPL recharge the baildown test data were not suitable for evaluation by the standard analytical solutions Instead they were analyzed using Eq 1 and a constant rate of NAPL discharge to the well estimated from test data that likely represents formation drainage and an average NAPL drawdown induced during that period of the test This evaluation indicates a transmissivity of about 001 ft2day well below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016)

DNAPL recoverability testing was proposed to be completed at wells N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14 based on a review of historical gauging data that indicated measurable DNAPL was present at thicknesses greater than 03 feet and at a depth greater than the documented top of sump indicating a hydraulic connection at the time of the test between DNAPL present

in the wells and DNAPL in the surrounding formation Initial gauging was conducted prior to the event during which five of six wells met the thickness and formation connection criteria required to perform a baildown test at the well Baildown tests were completed in January 2017 While on-going gauging was conducted at the area wells for approximately eight weeks following the tests to assess recharge conditions in the well the portion of the tests that were able be evaluated quantitively ranged from approximately four to 28 hours Field data for the DNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for DNAPL baildown tests are included as Appendix C A summary of results is included on Tables 2 and 3 and are shown on Figure 2

Quantitative transmissivity evaluations were completed for four wells N2SC-1I N2SC-1I(R) N2SC-03I(R) and N2SC-14 based on the results of the tests and subsequent gauging At all four wells the tests were analyzed using the API Workbook to determine a transmissivity at the well At three wells a constant NAPL dischargedrawdown analysis was also conducted for a portion of the test where test data likely represents formation drainage

Well N2SC-1I Baildown test results at well N2SC-1I were analyzed using the API Workbook (both BampR and CampJ methods) resulting in estimated transmissivity values above the criterion of recoverability of 08 ft2day The average transmissivity value was 28 ft2day though during the initial purge of DNAPL from the well less than 12 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered Most if not all of the recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-1I(R) which is only several feet away and screened across a similar interval indicated transmissivity values well below the 08 ft2day criteria which is further evidence that calculated recoverability was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-1I(R) Baildown tests at well N2SC-1I(R) were analyzed using both the API Workbook and a constant NAPL dischargedrawdown analysis resulting in estimated transmissivity values below the criterion of recoverability of 08 ft2day The average transmissivity value was 01 ft2day indicating DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I DNAPL was measured in well N2SC-03I at a depth below the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I(R) Baildown test results at well N2SC-03I(R) were analyzed using the API Workbook (both BampR and CampJ methods) and through a constant NAPL dischargedrawdown analysis Transmissivities determined at the well include one value above the 08 ft2day criteria and an average transmissivity of 05 ft2day During the initial purge of DNAPL from the well less

than 25 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered The recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-03I which is only several feet away and screened across a similar interval indicated no recharge from the formation following an initial recovery which is further evidence that calculated recoverability for well N2SC-03I(R) was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-13I Following initial recovery DNAPL was not measured in well N2SC-13I at a depth above the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-14 Gauging data collected from well N2SC-14 following the removal of DNAPL in the well sump indicated measurable DNAPL was present within the well screen interval only once during the initial and subsequent gauging that was conducted periodically for eight weeks following the initiation of the test Where DNAPL recharge is gauged only in the well sump evaluation by the API Workbook is not appropriate and an estimated transmissivity may be derived by utilizing a DNAPL drawdown consistent with the stable thickness in the screened interval and a constant DNAPL discharge determined through a calculation of measured volume of recharge to the well over a given time Late time series data was used to determine DNAPL discharge and DNAPL drawdown this way resulting in a transmissivity of 03 ft2day at the well below the criterion of recoverability of 08 ft2day These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

333 GMA3

Transmissivity testing was proposed to be completed at 13 wells in the GMA3 area based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet However during the pretest gauging only wells 51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17 had sufficient LNAPL thickness to perform either a LNAPL baildown or manual skimming test Over the course of approximately 8-weeks LNAPL thicknesses in the six wells without adequate thickness did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively Field data for the LNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown tests are included as Appendix C and manual skimming test input and output data are included as Appendix D and E respectively A summary of results is included on Tables 2 and 3 and are shown on Figure 3

Quantitative transmissivity evaluation was completed for all wells based on the results of the tests and subsequent gauging At two wells 51-08 and 51-19 the tests were analyzed using the BampR and CampJ

methods in the API Workbook to determine a transmissivity at the well (Table 2) Estimated transmissivity values were below the MassDEP and ITRC criterion of recoverability of 08 ft2day

Manual skimming tests were completed at 59-03R GMA3-12 and GMA-17 and analysis of the data was completed using Equation 1 (ASTM 2013) to estimate a transmissivity at each well The tests were completed in January 2017 and ranged in duration from approximately five to nine hours Periodic purging of LNAPL was performed to maintain an LNAPL thickness of less than 25 percent of the initial gauged thickness and only data that met that criteria were used in the analysis LNAPL transmissivity estimates for all three wells are below the criterion of recoverability of 08 ft2day indicating that continued hydraulic operations would not result in beneficial recovery of LNAPL from the subsurface near the wells

Where baildown test data are not suitable for analysis by the Bower amp Rice and Cooper amp Jacob method the data are analyzed using Eq 1 an estimated constant rate of NAPL discharge to the well from test data that best represents formation drainage and an average NAPL drawdown induced during that period of the test Data collected during tests conducted at wells 51-17 and 51-21 were evaluated in this manner The LNAPL transmissivity estimates 004 ft2day and 0002 ft2day respectively are both below the criterion of recoverability of 08 ft2day

4 CONCLUSIONS

Evaluation of the baildown and manual skimming tests indicate NAPL transmissivities were generally below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016) with two noted exceptions at wells N2SC-1I(R) and N2SC-03I(R) where only a small percentage of the total casing and filter pack volume was able to be removed at the start of the test likely resulting in initial filter pack drainage

Transmissivity calculations from LNAPL baildown tests LNAPL manual skimming tests and DNAPL baildown tests completed in GMA1 and GMA3 generally indicate that NAPL recovery potential at the Site from these specific systems are negligible NAPL transmissivities are below the criterion of recoverability of 08 ft2day (ITRC 2009) with the exception of well N2SC-01I and N2SC-03I(R) in GMA1 The estimated transmissivities at these two wells likely represent filter pack drainage and little if any of the longer-term potential for NAPL recoverability from the formation At N2SC-03I(R) the NAPL transmissivity estimate for only one of the three analysis methods exceeds the MassDEP and ITRC criterion Additionally tests conducted at or near wells with recovery systems in place indicate that further NAPL recovery will not provide a meaningful benefit for the Site A summary of activities conducted and conclusions reached for each area is included below

41 Conclusions for GMA1 East Street Area 1

Of the three wells proposed for testing only one well (106) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

The LNAPL transmissivity estimate for this area is 001 ft2day

42 Conclusions for GMA1 Newell Street Area II

Of the wells proposed for testing all six (N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14) met the criterion to be tested

DNAPL transmissivity estimates for this area ranged from near-zero to 28 ft2day with five of the six estimates below the 08 ft2day MassDEP and ITRC criterion The exceedance to the criteria is likely the result of initial filter pack drainage

43 Conclusions for GMA3

Of the 13 wells proposed for testing in this area only seven wells (51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

LNAPL transmissivity estimates for this area ranged from 0002 ft2day to 04 ft2day

5 RECOMMENDATIONS

Currently in-well NAPL thickness is the criteria by which NAPL recovery at a well is determined to be required In accordance with recently developed standards and guidance endorsed by ITRC ASTM and a number of state agencies including MassDEP it is recommended that NAPL transmissivity data be used to develop a riskbenefit-based approach to NAPL recovery and management at the Site NAPL transmissivity rather than measured NAPL thickness is the most appropriate indicator of the potential for NAPL recovery to provide beneficial reduction in NAPL mass Specific recommendations for changes to the recovery criteria and management program are provided below

51 Recommendations for GMA1 East Street Area 1

Operation of the LNAPL recovery systems in this area should be discontinued because recovery by hydraulic methods in this area is unlikely to beneficially reduce LNAPL in the subsurface

LNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

Fluid level gauging should continue within the well network to monitor LNAPL thickness in wells where it has historically been observed

52 Recommendations for GMA1 Newell Street Area II

Operation of the DNAPL recovery system should be discontinued because DNAPL recovery by hydraulic methods in this area is unlikely to beneficially reduce NAPL in the subsurface

Periodic DNAPL recovery by manual bailing should be continued at wells where transmissivity is found to be greater than 08 ft2day when Site-specific recovery criteria are met

DNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

in the wells and DNAPL in the surrounding formation Initial gauging was conducted prior to the event during which five of six wells met the thickness and formation connection criteria required to perform a baildown test at the well Baildown tests were completed in January 2017 While on-going gauging was conducted at the area wells for approximately eight weeks following the tests to assess recharge conditions in the well the portion of the tests that were able be evaluated quantitively ranged from approximately four to 28 hours Field data for the DNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for DNAPL baildown tests are included as Appendix C A summary of results is included on Tables 2 and 3 and are shown on Figure 2

Quantitative transmissivity evaluations were completed for four wells N2SC-1I N2SC-1I(R) N2SC-03I(R) and N2SC-14 based on the results of the tests and subsequent gauging At all four wells the tests were analyzed using the API Workbook to determine a transmissivity at the well At three wells a constant NAPL dischargedrawdown analysis was also conducted for a portion of the test where test data likely represents formation drainage

Well N2SC-1I Baildown test results at well N2SC-1I were analyzed using the API Workbook (both BampR and CampJ methods) resulting in estimated transmissivity values above the criterion of recoverability of 08 ft2day The average transmissivity value was 28 ft2day though during the initial purge of DNAPL from the well less than 12 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered Most if not all of the recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-1I(R) which is only several feet away and screened across a similar interval indicated transmissivity values well below the 08 ft2day criteria which is further evidence that calculated recoverability was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-1I(R) Baildown tests at well N2SC-1I(R) were analyzed using both the API Workbook and a constant NAPL dischargedrawdown analysis resulting in estimated transmissivity values below the criterion of recoverability of 08 ft2day The average transmissivity value was 01 ft2day indicating DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I DNAPL was measured in well N2SC-03I at a depth below the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-03I(R) Baildown test results at well N2SC-03I(R) were analyzed using the API Workbook (both BampR and CampJ methods) and through a constant NAPL dischargedrawdown analysis Transmissivities determined at the well include one value above the 08 ft2day criteria and an average transmissivity of 05 ft2day During the initial purge of DNAPL from the well less

than 25 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered The recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-03I which is only several feet away and screened across a similar interval indicated no recharge from the formation following an initial recovery which is further evidence that calculated recoverability for well N2SC-03I(R) was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-13I Following initial recovery DNAPL was not measured in well N2SC-13I at a depth above the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-14 Gauging data collected from well N2SC-14 following the removal of DNAPL in the well sump indicated measurable DNAPL was present within the well screen interval only once during the initial and subsequent gauging that was conducted periodically for eight weeks following the initiation of the test Where DNAPL recharge is gauged only in the well sump evaluation by the API Workbook is not appropriate and an estimated transmissivity may be derived by utilizing a DNAPL drawdown consistent with the stable thickness in the screened interval and a constant DNAPL discharge determined through a calculation of measured volume of recharge to the well over a given time Late time series data was used to determine DNAPL discharge and DNAPL drawdown this way resulting in a transmissivity of 03 ft2day at the well below the criterion of recoverability of 08 ft2day These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Transmissivity testing was proposed to be completed at 13 wells in the GMA3 area based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet However during the pretest gauging only wells 51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17 had sufficient LNAPL thickness to perform either a LNAPL baildown or manual skimming test Over the course of approximately 8-weeks LNAPL thicknesses in the six wells without adequate thickness did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively Field data for the LNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown tests are included as Appendix C and manual skimming test input and output data are included as Appendix D and E respectively A summary of results is included on Tables 2 and 3 and are shown on Figure 3

Quantitative transmissivity evaluation was completed for all wells based on the results of the tests and subsequent gauging At two wells 51-08 and 51-19 the tests were analyzed using the BampR and CampJ

methods in the API Workbook to determine a transmissivity at the well (Table 2) Estimated transmissivity values were below the MassDEP and ITRC criterion of recoverability of 08 ft2day

Manual skimming tests were completed at 59-03R GMA3-12 and GMA-17 and analysis of the data was completed using Equation 1 (ASTM 2013) to estimate a transmissivity at each well The tests were completed in January 2017 and ranged in duration from approximately five to nine hours Periodic purging of LNAPL was performed to maintain an LNAPL thickness of less than 25 percent of the initial gauged thickness and only data that met that criteria were used in the analysis LNAPL transmissivity estimates for all three wells are below the criterion of recoverability of 08 ft2day indicating that continued hydraulic operations would not result in beneficial recovery of LNAPL from the subsurface near the wells

Where baildown test data are not suitable for analysis by the Bower amp Rice and Cooper amp Jacob method the data are analyzed using Eq 1 an estimated constant rate of NAPL discharge to the well from test data that best represents formation drainage and an average NAPL drawdown induced during that period of the test Data collected during tests conducted at wells 51-17 and 51-21 were evaluated in this manner The LNAPL transmissivity estimates 004 ft2day and 0002 ft2day respectively are both below the criterion of recoverability of 08 ft2day

4 CONCLUSIONS

Evaluation of the baildown and manual skimming tests indicate NAPL transmissivities were generally below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016) with two noted exceptions at wells N2SC-1I(R) and N2SC-03I(R) where only a small percentage of the total casing and filter pack volume was able to be removed at the start of the test likely resulting in initial filter pack drainage

Transmissivity calculations from LNAPL baildown tests LNAPL manual skimming tests and DNAPL baildown tests completed in GMA1 and GMA3 generally indicate that NAPL recovery potential at the Site from these specific systems are negligible NAPL transmissivities are below the criterion of recoverability of 08 ft2day (ITRC 2009) with the exception of well N2SC-01I and N2SC-03I(R) in GMA1 The estimated transmissivities at these two wells likely represent filter pack drainage and little if any of the longer-term potential for NAPL recoverability from the formation At N2SC-03I(R) the NAPL transmissivity estimate for only one of the three analysis methods exceeds the MassDEP and ITRC criterion Additionally tests conducted at or near wells with recovery systems in place indicate that further NAPL recovery will not provide a meaningful benefit for the Site A summary of activities conducted and conclusions reached for each area is included below

41 Conclusions for GMA1 East Street Area 1

Of the three wells proposed for testing only one well (106) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

The LNAPL transmissivity estimate for this area is 001 ft2day

42 Conclusions for GMA1 Newell Street Area II

Of the wells proposed for testing all six (N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14) met the criterion to be tested

DNAPL transmissivity estimates for this area ranged from near-zero to 28 ft2day with five of the six estimates below the 08 ft2day MassDEP and ITRC criterion The exceedance to the criteria is likely the result of initial filter pack drainage

43 Conclusions for GMA3

Of the 13 wells proposed for testing in this area only seven wells (51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

LNAPL transmissivity estimates for this area ranged from 0002 ft2day to 04 ft2day

5 RECOMMENDATIONS

Currently in-well NAPL thickness is the criteria by which NAPL recovery at a well is determined to be required In accordance with recently developed standards and guidance endorsed by ITRC ASTM and a number of state agencies including MassDEP it is recommended that NAPL transmissivity data be used to develop a riskbenefit-based approach to NAPL recovery and management at the Site NAPL transmissivity rather than measured NAPL thickness is the most appropriate indicator of the potential for NAPL recovery to provide beneficial reduction in NAPL mass Specific recommendations for changes to the recovery criteria and management program are provided below

51 Recommendations for GMA1 East Street Area 1

Operation of the LNAPL recovery systems in this area should be discontinued because recovery by hydraulic methods in this area is unlikely to beneficially reduce LNAPL in the subsurface

LNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

Fluid level gauging should continue within the well network to monitor LNAPL thickness in wells where it has historically been observed

52 Recommendations for GMA1 Newell Street Area II

Operation of the DNAPL recovery system should be discontinued because DNAPL recovery by hydraulic methods in this area is unlikely to beneficially reduce NAPL in the subsurface

Periodic DNAPL recovery by manual bailing should be continued at wells where transmissivity is found to be greater than 08 ft2day when Site-specific recovery criteria are met

DNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

than 25 percent of the total DNAPL volume estimated to be present in the casing and filter pack was recovered The recharge observed in the well is likely due to filter pack drainage into the well and is not representative of recoverability from the formation Transmissivity testing at nearby well N2SC-03I which is only several feet away and screened across a similar interval indicated no recharge from the formation following an initial recovery which is further evidence that calculated recoverability for well N2SC-03I(R) was likely the result of initial filter pack drainage These results indicate DNAPL recovery by hydraulic methods would likely not lead to significant mass removal or remedial benefit

Well N2SC-13I Following initial recovery DNAPL was not measured in well N2SC-13I at a depth above the bottom of the well screen interval (ie DNAPL was only in the well sump) indicating the DNAPL in the well was not in connection with the mobile NAPL interval in the surrounding formation and that DNAPL was not actively discharging to the well Qualitatively a near-zero transmissivity is assumed for the well during the testing period as no DNAPL recharge to the well was observed These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

Well N2SC-14 Gauging data collected from well N2SC-14 following the removal of DNAPL in the well sump indicated measurable DNAPL was present within the well screen interval only once during the initial and subsequent gauging that was conducted periodically for eight weeks following the initiation of the test Where DNAPL recharge is gauged only in the well sump evaluation by the API Workbook is not appropriate and an estimated transmissivity may be derived by utilizing a DNAPL drawdown consistent with the stable thickness in the screened interval and a constant DNAPL discharge determined through a calculation of measured volume of recharge to the well over a given time Late time series data was used to determine DNAPL discharge and DNAPL drawdown this way resulting in a transmissivity of 03 ft2day at the well below the criterion of recoverability of 08 ft2day These results indicate DNAPL recovery by hydraulic methods would not lead to significant mass removal or remedial benefit

333 GMA3

Transmissivity testing was proposed to be completed at 13 wells in the GMA3 area based on a review of historical gauging data that indicated measurable LNAPL was present at thicknesses greater than 03 feet However during the pretest gauging only wells 51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17 had sufficient LNAPL thickness to perform either a LNAPL baildown or manual skimming test Over the course of approximately 8-weeks LNAPL thicknesses in the six wells without adequate thickness did not reach the minimum thickness established to perform a transmissivity test that could be analyzed quantitatively Field data for the LNAPL baildown tests are included in Appendix B and the API Workbook (API 2012) output data for LNAPL baildown tests are included as Appendix C and manual skimming test input and output data are included as Appendix D and E respectively A summary of results is included on Tables 2 and 3 and are shown on Figure 3

Quantitative transmissivity evaluation was completed for all wells based on the results of the tests and subsequent gauging At two wells 51-08 and 51-19 the tests were analyzed using the BampR and CampJ

methods in the API Workbook to determine a transmissivity at the well (Table 2) Estimated transmissivity values were below the MassDEP and ITRC criterion of recoverability of 08 ft2day

Manual skimming tests were completed at 59-03R GMA3-12 and GMA-17 and analysis of the data was completed using Equation 1 (ASTM 2013) to estimate a transmissivity at each well The tests were completed in January 2017 and ranged in duration from approximately five to nine hours Periodic purging of LNAPL was performed to maintain an LNAPL thickness of less than 25 percent of the initial gauged thickness and only data that met that criteria were used in the analysis LNAPL transmissivity estimates for all three wells are below the criterion of recoverability of 08 ft2day indicating that continued hydraulic operations would not result in beneficial recovery of LNAPL from the subsurface near the wells

Where baildown test data are not suitable for analysis by the Bower amp Rice and Cooper amp Jacob method the data are analyzed using Eq 1 an estimated constant rate of NAPL discharge to the well from test data that best represents formation drainage and an average NAPL drawdown induced during that period of the test Data collected during tests conducted at wells 51-17 and 51-21 were evaluated in this manner The LNAPL transmissivity estimates 004 ft2day and 0002 ft2day respectively are both below the criterion of recoverability of 08 ft2day

4 CONCLUSIONS

Evaluation of the baildown and manual skimming tests indicate NAPL transmissivities were generally below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016) with two noted exceptions at wells N2SC-1I(R) and N2SC-03I(R) where only a small percentage of the total casing and filter pack volume was able to be removed at the start of the test likely resulting in initial filter pack drainage

Transmissivity calculations from LNAPL baildown tests LNAPL manual skimming tests and DNAPL baildown tests completed in GMA1 and GMA3 generally indicate that NAPL recovery potential at the Site from these specific systems are negligible NAPL transmissivities are below the criterion of recoverability of 08 ft2day (ITRC 2009) with the exception of well N2SC-01I and N2SC-03I(R) in GMA1 The estimated transmissivities at these two wells likely represent filter pack drainage and little if any of the longer-term potential for NAPL recoverability from the formation At N2SC-03I(R) the NAPL transmissivity estimate for only one of the three analysis methods exceeds the MassDEP and ITRC criterion Additionally tests conducted at or near wells with recovery systems in place indicate that further NAPL recovery will not provide a meaningful benefit for the Site A summary of activities conducted and conclusions reached for each area is included below

41 Conclusions for GMA1 East Street Area 1

Of the three wells proposed for testing only one well (106) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

The LNAPL transmissivity estimate for this area is 001 ft2day

42 Conclusions for GMA1 Newell Street Area II

Of the wells proposed for testing all six (N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14) met the criterion to be tested

DNAPL transmissivity estimates for this area ranged from near-zero to 28 ft2day with five of the six estimates below the 08 ft2day MassDEP and ITRC criterion The exceedance to the criteria is likely the result of initial filter pack drainage

43 Conclusions for GMA3

Of the 13 wells proposed for testing in this area only seven wells (51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

LNAPL transmissivity estimates for this area ranged from 0002 ft2day to 04 ft2day

5 RECOMMENDATIONS

Currently in-well NAPL thickness is the criteria by which NAPL recovery at a well is determined to be required In accordance with recently developed standards and guidance endorsed by ITRC ASTM and a number of state agencies including MassDEP it is recommended that NAPL transmissivity data be used to develop a riskbenefit-based approach to NAPL recovery and management at the Site NAPL transmissivity rather than measured NAPL thickness is the most appropriate indicator of the potential for NAPL recovery to provide beneficial reduction in NAPL mass Specific recommendations for changes to the recovery criteria and management program are provided below

51 Recommendations for GMA1 East Street Area 1

Operation of the LNAPL recovery systems in this area should be discontinued because recovery by hydraulic methods in this area is unlikely to beneficially reduce LNAPL in the subsurface

LNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

Fluid level gauging should continue within the well network to monitor LNAPL thickness in wells where it has historically been observed

52 Recommendations for GMA1 Newell Street Area II

Operation of the DNAPL recovery system should be discontinued because DNAPL recovery by hydraulic methods in this area is unlikely to beneficially reduce NAPL in the subsurface

Periodic DNAPL recovery by manual bailing should be continued at wells where transmissivity is found to be greater than 08 ft2day when Site-specific recovery criteria are met

DNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

GMA 1 AND 3 ndash TRANSMISSIVITY ASSESSMENT AND RECOVERY RECOMMENDATIONS

methods in the API Workbook to determine a transmissivity at the well (Table 2) Estimated transmissivity values were below the MassDEP and ITRC criterion of recoverability of 08 ft2day

Manual skimming tests were completed at 59-03R GMA3-12 and GMA-17 and analysis of the data was completed using Equation 1 (ASTM 2013) to estimate a transmissivity at each well The tests were completed in January 2017 and ranged in duration from approximately five to nine hours Periodic purging of LNAPL was performed to maintain an LNAPL thickness of less than 25 percent of the initial gauged thickness and only data that met that criteria were used in the analysis LNAPL transmissivity estimates for all three wells are below the criterion of recoverability of 08 ft2day indicating that continued hydraulic operations would not result in beneficial recovery of LNAPL from the subsurface near the wells

Where baildown test data are not suitable for analysis by the Bower amp Rice and Cooper amp Jacob method the data are analyzed using Eq 1 an estimated constant rate of NAPL discharge to the well from test data that best represents formation drainage and an average NAPL drawdown induced during that period of the test Data collected during tests conducted at wells 51-17 and 51-21 were evaluated in this manner The LNAPL transmissivity estimates 004 ft2day and 0002 ft2day respectively are both below the criterion of recoverability of 08 ft2day

4 CONCLUSIONS

Evaluation of the baildown and manual skimming tests indicate NAPL transmissivities were generally below the criterion of recoverability of 08 ft2day (ITRC 2009 MassDEP 2016) with two noted exceptions at wells N2SC-1I(R) and N2SC-03I(R) where only a small percentage of the total casing and filter pack volume was able to be removed at the start of the test likely resulting in initial filter pack drainage

Transmissivity calculations from LNAPL baildown tests LNAPL manual skimming tests and DNAPL baildown tests completed in GMA1 and GMA3 generally indicate that NAPL recovery potential at the Site from these specific systems are negligible NAPL transmissivities are below the criterion of recoverability of 08 ft2day (ITRC 2009) with the exception of well N2SC-01I and N2SC-03I(R) in GMA1 The estimated transmissivities at these two wells likely represent filter pack drainage and little if any of the longer-term potential for NAPL recoverability from the formation At N2SC-03I(R) the NAPL transmissivity estimate for only one of the three analysis methods exceeds the MassDEP and ITRC criterion Additionally tests conducted at or near wells with recovery systems in place indicate that further NAPL recovery will not provide a meaningful benefit for the Site A summary of activities conducted and conclusions reached for each area is included below

41 Conclusions for GMA1 East Street Area 1

Of the three wells proposed for testing only one well (106) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

The LNAPL transmissivity estimate for this area is 001 ft2day

42 Conclusions for GMA1 Newell Street Area II

Of the wells proposed for testing all six (N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14) met the criterion to be tested

DNAPL transmissivity estimates for this area ranged from near-zero to 28 ft2day with five of the six estimates below the 08 ft2day MassDEP and ITRC criterion The exceedance to the criteria is likely the result of initial filter pack drainage

43 Conclusions for GMA3

Of the 13 wells proposed for testing in this area only seven wells (51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

LNAPL transmissivity estimates for this area ranged from 0002 ft2day to 04 ft2day

5 RECOMMENDATIONS

Currently in-well NAPL thickness is the criteria by which NAPL recovery at a well is determined to be required In accordance with recently developed standards and guidance endorsed by ITRC ASTM and a number of state agencies including MassDEP it is recommended that NAPL transmissivity data be used to develop a riskbenefit-based approach to NAPL recovery and management at the Site NAPL transmissivity rather than measured NAPL thickness is the most appropriate indicator of the potential for NAPL recovery to provide beneficial reduction in NAPL mass Specific recommendations for changes to the recovery criteria and management program are provided below

51 Recommendations for GMA1 East Street Area 1

Operation of the LNAPL recovery systems in this area should be discontinued because recovery by hydraulic methods in this area is unlikely to beneficially reduce LNAPL in the subsurface

LNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

Fluid level gauging should continue within the well network to monitor LNAPL thickness in wells where it has historically been observed

52 Recommendations for GMA1 Newell Street Area II

Operation of the DNAPL recovery system should be discontinued because DNAPL recovery by hydraulic methods in this area is unlikely to beneficially reduce NAPL in the subsurface

Periodic DNAPL recovery by manual bailing should be continued at wells where transmissivity is found to be greater than 08 ft2day when Site-specific recovery criteria are met

DNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

GMA 1 AND 3 ndash TRANSMISSIVITY ASSESSMENT AND RECOVERY RECOMMENDATIONS

42 Conclusions for GMA1 Newell Street Area II

Of the wells proposed for testing all six (N2SC-1I N2SC-1I(R) N2SC-03I N2SC-03I(R) N2SC-13I and N2SC-14) met the criterion to be tested

DNAPL transmissivity estimates for this area ranged from near-zero to 28 ft2day with five of the six estimates below the 08 ft2day MassDEP and ITRC criterion The exceedance to the criteria is likely the result of initial filter pack drainage

43 Conclusions for GMA3

Of the 13 wells proposed for testing in this area only seven wells (51-08 51-17 51-19 51-21 59-03R GMA3-12 and GMA3-17) met the criterion to be tested The remaining wells had insufficient NAPL present to perform testing suitable for quantitative evaluation of transmissivity

LNAPL transmissivity estimates for this area ranged from 0002 ft2day to 04 ft2day

5 RECOMMENDATIONS

Currently in-well NAPL thickness is the criteria by which NAPL recovery at a well is determined to be required In accordance with recently developed standards and guidance endorsed by ITRC ASTM and a number of state agencies including MassDEP it is recommended that NAPL transmissivity data be used to develop a riskbenefit-based approach to NAPL recovery and management at the Site NAPL transmissivity rather than measured NAPL thickness is the most appropriate indicator of the potential for NAPL recovery to provide beneficial reduction in NAPL mass Specific recommendations for changes to the recovery criteria and management program are provided below

51 Recommendations for GMA1 East Street Area 1

Operation of the LNAPL recovery systems in this area should be discontinued because recovery by hydraulic methods in this area is unlikely to beneficially reduce LNAPL in the subsurface

LNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

Fluid level gauging should continue within the well network to monitor LNAPL thickness in wells where it has historically been observed

52 Recommendations for GMA1 Newell Street Area II

Operation of the DNAPL recovery system should be discontinued because DNAPL recovery by hydraulic methods in this area is unlikely to beneficially reduce NAPL in the subsurface

Periodic DNAPL recovery by manual bailing should be continued at wells where transmissivity is found to be greater than 08 ft2day when Site-specific recovery criteria are met

DNAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day

Note Standard Criteria for manual NAPL removal during monitoring is 025 ft of LNAPL andor 05 ft of DNAPL (Arcadis 2017ab)

53 Recommendations for GMA3

Operation of the LNAPL recovery systems in this area should be discontinued because LNAPL recovery by hydraulic methods in this area is unlikely to beneficially reduce LNAPL in the subsurface

Fluid level gauging should continue within the well network to monitor LNAPL thickness in wells where it has historically been observed

NAPL recovery by manual bailing should be discontinued at wells where transmissivity is found to be less than 08 ft2day
