1.0 INTRODUCTION The Air Force Civil Engineer Center (AFCEC) has contracted EA Engineering, Science, and Technology, Inc. (EA) to perform a supplemental remedial investigation (SRI) at Source Areas WP45 (Photo Lab) and SS57 (Fire Station Parking Lot) (hereinafter identified as WP45/SS57), within Operable Unit (OU) 3 at Eielson Air Force Base (AFB), Alaska. A Quality Assurance Project Plan (QAPP) was prepared for this investigation and the Final Version 3 of this QAPP (U.S. Air Force [USAF] 2012a) was approved by the U.S. Environmental Protection Agency (USEPA) and Alaska Department of Environmental Conservation (ADEC) on 7 May 2012. This addendum has been prepared to address additional investigation activities to be performed in association with releases from the Photo Lab, WP45, as per stakeholders’ decision at the 23 November 2011 meeting. A stakeholders scoping meeting took place at the ADEC office in Fairbanks, Alaska, on 30 August 2012. Participants, either present in the room or via telephone, included the following:

• David Beistel – Eielson AFB • Joann Socash – Booz Allen Hamilton/AFCEC • Kimberly DeRuyter –ADEC • Eric Breitenberger – ADEC • Aaron Lambert – U.S. Environmental Protection Agency (EPA) • Kelly Findlay – EA • Cristina Radu – EA • Jay Snyder – EA • Kyle Waldron – EA • Mark Wilkinson – EA

During this scoping meeting, the stakeholders agreed upon the scope of work for this additional investigation. Because this QAPP Addendum No. 1 expands from the list of contaminants of concern from those addressed in the WP45/SS57 Final Version 3 Revision 1 QAPP to include two metals (silver and chromium), the stakeholders also agreed during the 23 November 2011 meeting that the requirements for the analytical laboratory will be those specified for these analytes in the Final Version 2 Revision 1 Installation-Wide Generic QAPP (USAF 2012b). 2.0 BACKGROUND Source Area WP45 is located around Building 1183 where a small photography laboratory was formerly operated. A dry well located adjacent to Building 1183 has received photographic waste from the shop. Photographs of this dry well, as shown in the Phase II Class V Underground Injection Control (UIC) Implementation Report (USAF 2011), are included in Appendix A. Appendix B contains the Response to Comments received in the letter with the conditional approval of the Draft QAPP Addendum No. 1 for SRI for Source Areas WP45/SS57 (ADEC/EPA 2012).



Building 1183 includes a parking garage, washing facility, and offices. The dry well consists of a 4.5-foot-diameter steel casing located at the northwest side of the building. The bottom of the well is 8.3 feet (ft) below the top of casing. The dry well has not been removed because its removal could compromise the structure of the building. However, the drain leading to the well was plugged with cement in 1993 (USAF 2009). 3.0 PREVIOUS SAMPLING The dry well at Building 1183 was identified during an installation-wide Class V UIC inventory (USAF 2009). During a pre-closure investigation in May 2010, water was observed in the bottom of the well. In May and July 2011, water was not observed in the well but at that time samples of solid media from the bottom of the well were collected for pre-closure characterization. These samples were analyzed for gasoline range organics (GRO), diesel range organics (DRO), volatile organic compounds (VOC), semivolatile organic compounds (SVOC), metals, and pesticides. Pre-closure sample results were presented in the Final Work Plan Phase II Class V UIC Implementation and Close Class V UIC Structures (USAF 2011). DRO and metals were the only COCs detected at concentrations above the laboratory reporting limits. Although the sampled media should not be considered soil, the results were compared to ADEC Method Two Soil Cleanup Levels (Alaska Administrative Code 2012) as a reference. DRO, arsenic, chromium, and silver were detected at concentrations exceeding the soil cleanup levels for the migration-to-groundwater pathway. Results of Toxicity Characteristic Leaching Procedure (TCLP) metals analysis indicated that the material in the dry well is not a Resource Conservation and Recovery Act (RCRA) hazardous waste. 4.0 SAMPLING RATIONALE, MEDIA, AND ANALYTICAL SUITES The sampling program associated with the Photo Lab is based on the agreement reached with the stakeholders during the scoping meeting on 30 August 2012. Table 1 presents the matrices to be sampled, samples to be collected and rationale for collection, sampling depths, analytical suites, sample IDs, sampling tools, standard operating procedures (SOPs) to be employed, and QC samples applicable for each medium. Sampling locations are provided in Figure 1. Further details of the soil and groundwater sampling are provided below. Soil Characterization:

• One soil boring (SB28) will be completed adjacent to the dry well, near the pipe penetration point. Of note, access may be partially limited due to the presence of an overhead power line at the dry well. Although field conditions at SB28 as of 11 January



2013 do not indicate there may be a problem with the boring installation, the regulators will be contacted in case the boring needs to be moved.

• Two soil samples will be collected from this boring, as follows:

− 1) One sample will be collected immediately below the pipe penetration depth (as the most likely interval to be contaminated by possible leakage from the dry well at the pipe entry point)

− 2) One sample will be collected at the groundwater interface.

• Analytical suite: Soil samples will be analyzed for silver and chromium using EPA

Method 6020.

Groundwater Characterization:

• One existing monitoring well (45M01), located northwest of the dry well will be sampled. This well was not included in the 2011 SRI sampling event.

• One new monitoring well will be installed downgradient from the dry well and sampled. The stakeholders may decide to locate one of the groundwater monitoring wells proposed for installation as part of the 2012 SRI activities closer to the dry well.

• Water table monitoring well(s) will be constructed using regulator approved methods; well development and sample collection will be performed according to approved procedures.

• Analytical suite: Due to the locations of these wells and former detections of organic compounds, the groundwater samples will be analyzed for silver using EPA Method 6020 and the organic compounds of concern identified in the WP45/SS57 QAPP including GRO using Method AK101, DRO using Method AK102, residual range organics (RRO using Method AK103, VOCs using EPA Method 8260B, ethylene dibromide (EDB) using EPA Method 8011, and PAHs using EPA Method 8270C using selected ion monitoring mode. In addition, groundwater will be field analyzed for temperature, pH, specific conductivity, oxidation-reduction potential, dissolved oxygen, and turbidity.

Table 1 includes the environmental and quality control (QC) samples applicable to this additional soil and groundwater characterization. 5.0 DECISIONS

Soil and groundwater data will be evaluated based on the same “if/then” statements described in Worksheet #10 of the QAPP for the SRI at WP45/SS57 (USAF 2012a). Stakeholders will determine the path forward based on the sample results.

Sample location was chosen to capture the area with the highest likelihood of soil contamination on the side of the dry well where the concrete culvert

is penetrated by the metal pipe.

The first interval to be sampled is immediately below the point where the metal pipe penetrates the dry well. Estimated penetration depth is 6.5 ft

bgs.

The second interval to be sampled is above the capillary fringe. The sampling depth will depend on

the depth to groundwater. For purposes of well design, the top of the capillary fringe is assumed to

be 1 ft above the highest seasonal water table elevation.

Table 1 Proposed Field Sampling for Investigation of a Potential Release from the Photo Lab, Source Area WP45, Eielson Air Force Base, Alaska








1.0 INTRODUCTION The Air Force Civil Engineer Center (AFCEC) has contracted EA Engineering, Science, and Technology, Inc. (EA) to perform a supplemental remedial investigation (SRI) at Source Areas WP45 (Photo Lab) and SS57 (Fire Station Parking Lot) (hereinafter identified as WP45/SS57), within Operable Unit (OU) 3 at Eielson Air Force Base (AFB), Alaska. A Quality Assurance Project Plan (QAPP) was prepared for this investigation and the Final Version 3 of this QAPP (U.S. Air Force [USAF] 2012a) was approved by the U.S. Environmental Protection Agency (USEPA) and Alaska Department of Environmental Conservation (ADEC) on 7 May 2012. This addendum has been prepared to address additional investigation activities to be performed in association with releases from the Photo Lab, WP45, as per stakeholders’ decision at the 23 November 2011 meeting. A stakeholders scoping meeting took place at the ADEC office in Fairbanks, Alaska, on 30 August 2012. Participants, either present in the room or via telephone, included the following:

• David Beistel – Eielson AFB • Joann Socash – Booz Allen Hamilton/AFCEC • Kimberly DeRuyter –ADEC • Eric Breitenberger – ADEC • Aaron Lambert – U.S. Environmental Protection Agency (EPA) • Kelly Findlay – EA • Cristina Radu – EA • Jay Snyder – EA • Kyle Waldron – EA • Mark Wilkinson – EA

During this scoping meeting, the stakeholders agreed upon the scope of work for this additional investigation. Because this QAPP Addendum No. 1 expands from the list of contaminants of concern from those addressed in the WP45/SS57 Final Version 3 Revision 1 QAPP to include two metals (silver and chromium), the stakeholders also agreed during the 23 November 2011 meeting that the requirements for the analytical laboratory will be those specified for these analytes in the Final Version 2 Revision 1 Installation-Wide Generic QAPP (USAF 2012b). 2.0 BACKGROUND Source Area WP45 is located around Building 1183 where a small photography laboratory was formerly operated. A dry well located adjacent to Building 1183 has received photographic waste from the shop. Photographs of this dry well, as shown in the Phase II Class V Underground Injection Control (UIC) Implementation Report (USAF 2011), are included in Appendix A. Appendix B contains the Response to Comments received in the letter with the conditional approval of the Draft QAPP Addendum No. 1 for SRI for Source Areas WP45/SS57 (ADEC/EPA 2012).




Building 1183 includes a parking garage, washing facility, and offices. The dry well consists of a 4.5-foot-diameter steel casing located at the northwest side of the building. The bottom of the well is 8.3 feet (ft) below the top of casing. The dry well has not been removed because its removal could compromise the structure of the building. However, the drain leading to the well was plugged with cement in 1993 (USAF 2009). 3.0 PREVIOUS SAMPLING The dry well at Building 1183 was identified during an installation-wide Class V UIC inventory (USAF 2009). During a pre-closure investigation in May 2010, water was observed in the bottom of the well. In May and July 2011, water was not observed in the well but at that time samples of solid media from the bottom of the well were collected for pre-closure characterization. These samples were analyzed for gasoline range organics (GRO), diesel range organics (DRO), volatile organic compounds (VOC), semivolatile organic compounds (SVOC), metals, and pesticides. Pre-closure sample results were presented in the Final Work Plan Phase II Class V UIC Implementation and Close Class V UIC Structures (USAF 2011). DRO and metals were the only COCs detected at concentrations above the laboratory reporting limits. Although the sampled media should not be considered soil, the results were compared to ADEC Method Two Soil Cleanup Levels (Alaska Administrative Code 2012) as a reference. DRO, arsenic, chromium, and silver were detected at concentrations exceeding the soil cleanup levels for the migration-to-groundwater pathway. Results of Toxicity Characteristic Leaching Procedure (TCLP) metals analysis indicated that the material in the dry well is not a Resource Conservation and Recovery Act (RCRA) hazardous waste. 4.0 SAMPLING RATIONALE, MEDIA, AND ANALYTICAL SUITES The sampling program associated with the Photo Lab is based on the agreement reached with the stakeholders during the scoping meeting on 30 August 2012. Table 1 presents the matrices to be sampled, samples to be collected and rationale for collection, sampling depths, analytical suites, sample IDs, sampling tools, standard operating procedures (SOPs) to be employed, and QC samples applicable for each medium. Sampling locations are provided in Figure 1. Further details of the soil and groundwater sampling are provided below. Soil Characterization:

• One soil boring (SB28) will be completed adjacent to the dry well, near the pipe penetration point. Of note, access may be partially limited due to the presence of an overhead power line at the dry well. Although field conditions at SB28 as of 11 January

Deleted: material

Comment [KF2]: Comment #2, Previous Sampling Section 3.0




2013 do not indicate there may be a problem with the boring installation, the regulators will be contacted in case the boring needs to be moved.

• Two soil samples will be collected from this boring, as follows:

− 1) One sample will be collected immediately below the pipe penetration depth (as the most likely interval to be contaminated by possible leakage from the dry well at the pipe entry point)

− 2) One sample will be collected at the groundwater interface.

• Analytical suite: Soil samples will be analyzed for silver and chromium using EPA

Method 6020.

Groundwater Characterization:

• One existing monitoring well (45M01), located northwest of the dry well will be sampled. This well was not included in the 2011 SRI sampling event.

• One new monitoring well will be installed downgradient from the dry well and sampled. The stakeholders may decide to locate one of the groundwater monitoring wells proposed for installation as part of the 2012 SRI activities closer to the dry well.

• Water table monitoring well(s) will be constructed using regulator approved methods; well development and sample collection will be performed according to approved procedures.

• Analytical suite: Due to the locations of these wells and former detections of organic compounds, the groundwater samples will be analyzed for silver using EPA Method 6020 and the organic compounds of concern identified in the WP45/SS57 QAPP including GRO using Method AK101, DRO using Method AK102, residual range organics (RRO using Method AK103, VOCs using EPA Method 8260B, ethylene dibromide (EDB) using EPA Method 8011, and PAHs using EPA Method 8270C using selected ion monitoring mode. In addition, groundwater will be field analyzed for temperature, pH, specific conductivity, oxidation-reduction potential, dissolved oxygen, and turbidity.

Table 1 includes the environmental and quality control (QC) samples applicable to this additional soil and groundwater characterization. 5.0 DECISIONS

Soil and groundwater data will be evaluated based on the same “if/then” statements described in Worksheet #10 of the QAPP for the SRI at WP45/SS57 (USAF 2012a). Stakeholders will determine the path forward based on the sample results.

Sample location was chosen to capture the area with the highest likelihood of soil contamination on the side of the dry well where the concrete culvert

is penetrated by the metal pipe.

The first interval to be sampled is immediately below the point where the metal pipe penetrates the dry well. Estimated penetration depth is 6.5 ft

bgs.

The second interval to be sampled is above the capillary fringe. The sampling depth will depend on

the depth to groundwater. For purposes of well design, the top of the capillary fringe is assumed to

be 1 ft above the highest seasonal water table elevation.
