EXECUTIVE SUMMARY

Accelerated Biological Treatment was evaluated as an alternative to the groundwater pump-and-

treat remedy selected in the 1997 Record of Decision (ROD). The Chemclene Site Defense

Group (CSDG) performed a field Pilot Test of Accelerated In-Situ Biological Treatment

following the completion of a laboratory bench scale study (microcosm study). This work was

performed in accordance with a Pilot Test Work Plan (Golder Associates, December 2002),

which was approved by the United States Environmental Protection Agency (USEPA) in January

2003.

The results of the Pilot Test provide field verification of the laboratory microcosm study and

suggest that this technology would provide for more effective control and. faster remediation of

residual groundwater impacts than the 1997 ROD remedy. Accelerated in-situ biological

treatment (Bioremediation) has two distinct advantages over conventional pump-and-treat

technology. First, VOCs are destroyed in place and, second, the biological activity produces

natural surfactants that strip VOCs from solid surfaces, vastly accelerating ground water

remediation. While groundwater analytical data collected during the Pre-Design Investigation

(PDI) indicated that attenuation of chlorinated volatile organic compounds (Cl-VOCs) was

occurring naturally, Bioremediation is an enhancement of this process.

An anaerobic treatment zone was established through nutrient enrichment and inoculation with a

selectively cultured consortium of halo-respiring bacteria. Although the initial Pilot Test period

has concluded, the CSDG continues to maintain this treatment zone, enhancing its development

in, and dovwigradient from, the source area (including the areas proximal to CC-6 and GW-1).

The treatment zone is evidenced by changes in numerous geochemical parameters. Among these

are:

• The near absence of dissolved oxygen (anaerobic conditions);

• Negative Oxidation-Reduction Potentials (ORP), indicative of a reducing environment; and

• Increased levels of Biological Oxygen Demand (BOD), indicative of increased biological activity.

February 2005 ES-2 003-6000

Decreasing tetrachloroethene (PCE) and trichloroethene (TCE) concentrations, increasing cis-1,2-

dichloroethene (cis-DCE) concentrations, and the production of vinyl chloride (VC) and ethenc

have been observed within the treatment zone. Specifically, the following trends are noted:

• Substantial conversion of PCE and TCE to cis-DCE at wells GW-1 and CC-6 since the beginning of the Pilot Test. Normalized ratio plots of concentration over time indicate that the relative proportion of cis-DCE to TCE and PCE has increased from less than 10% to almost 80% in these wells. By comparison, the relative proportion of cis-DCE to TCE and PCE has remained at less than 10% for the control wells CC-3 and GW-6 and other wells since the begirming of the Pilot Test (i.e., since the 2003 baseline testing data and the initial rounds of pilot test data), and is consistent with the data collected prior to the Pilot Test (i.e., the Preliminary Design Investigation data collected in 2001).

• Formation of a complete chain of dechlorination at well GW-1 from PCE/TGE through vinyl chloride and ethene. The efficacy of this decomposition chain is supported by a leveling off or decrease in the concentration of the intermediate compound, cis-DCE, in conjunction with an increased production of VC and ethene in this well observed towards the end of the Pilot Test.

As a comparison, control wells CC-3 andvpW-6j7which are located outside of the treatment zone. u

do not exhibit any of the above trends. i .

In addition, TCA and chloroform concentrations increased within the treatment zone at source

area well CC-6, while remaining relatively stable at downgradient well GW-1. These upward

trends in TCA and chloroform concentration in the source area may in part be the result of mole

fractionation. As dissolved and residual source area concentrations of PCE and TCE are reduced,

TCA and chloroform increasingly desorb off the rock and soil particles, resulting in increased

dissolved concentrations of these compounds. The Pilot Test data clearly show that nutrient

enrichment can significantly accelerate the rate of residual source material desorption and

destruction by microbial co-metabolism.

If enhancement of biodegradation is continued, it is expected that the rate of degradation of cis-

DCE and VC will accelerate throughout the treatment zone in the future as the biomass continues

to grow and residual source mass is depleted. Similarly, an increased rate leading to complete

degradation of TCA and chloroform is expected to occur commensurate with increased biomass

growth. These continued trends are supported by the thermodynamics of the system, the results

of the microcosm studies and the behavior observed at other sites (Ellis et al, 2000; Major et al.,

2001, Finn etal., 2003).

The CSDG is proposing to continue to operate and optimize performance of the system for an

estimated six (6) month period and develop the details necessary for fijll-scale design of the

groundwater remedy. This will provide continued active treatment of the plume and residual

source mass, while allowing the CSDG and the USEPA to verify the above conclusions,

particularly with regard to the timing of these later developing trends (i.e., more pronounced

degradation of cis-DCE and TCA and corresponding production of ethene and ethane). Once the

degree and timing of these trends can be more fully evaluated, and pending USEPA approval,

additional information will be collected to allow the system to be expanded and optimized for full

scale operation as a final remedy. At a minimum, the final system will be designed to establish a

treatment zone that controls and reduces all of the Cl-VOCs within the source and core plume

area.

1.0 INTRODUCTION

LI Purpose and Test Objectives

A Pilot Test has been conducted to demonstrate the feasibility of Accelerated In-Situ

Bioremediation (Bioremediation) as an alternative to the remedy that was selected in the 1997

Record of Decision (ROD) for remediating groundwater within the Main Plant Area (MPA)

portion of the Malvern TCE Superfiind Site (Site). This work was performed in accordance with

an Accelerated In-Situ Bioremediation Pilot Test Work Plan (Golder Associates, 2002a) that was

approved by the United States Environmental Protection Agency (USEPA) in January 2003. The

main objective of the Pilot Test was to demonstrate the viability of Bioremediation to control and

remediate impacted groundwater in the MPA and to provide data for use in designing a full-scale

Bioremediation system.

The specific objectives of the Pilot Test were to:

1. Verify hydrogeologic characteristics within the source area, (i.e., the targeted treatment zone);

2. Select an efficient electron donor and the appropriate electron donor injection concentration;

3. Confirm development and maintenance of appropriate geochemical conditions; including the ability to distribute nutrients and establish a treatment zone; and,

4. Verify effective biological treatment of chlorinated volatile organic compounds (Cl-VOCs).

This report presents a description of the work completed to date (including system installation,

bioaugmentation, electron donor addition and sampling and analysis), and provides a discussion

of the results observed to date and recommendations for the continued operation of the system as

Phase 1 of the groundwater remedy for the MPA.

1.2 Project Background

The Site location and a plan view of the MPA are shown on Figures 1 and 2, respectively.

Former Chemclene Corporation operations in the MPA included above-ground processing and

material storage (ASTs and drums) and underground storage (USTs) of chlorinated solvents.

Releases of Cl-VOCs from these activities, particularly in the northeastern portion of the MPA,

are believed to be the primary source of groundwater impacts.

USEPA characterized the nature and extent of environmental impacts during the Retnedial

Investigation (CH2MHill 1997). The Record of Decision (ROD) for the Site was subsequently

published in November 1997 (USEPA 1997). The ROD remedy for the MPA groundwater

consists of remediation of "the dissolved contaminant plume" through extraction, above ground-

treatment, and reinjection of treated groundwater. Monitored Natural Attenuation (MNA) was

also considered for remediation of the downgradient portion of the groundwater plume.

Golder Associates conducted a Pre-Design Investigation (PDI) in 2001 and 2002. The PDI Report

(Golder Associates, 2002b), which was approved by USEPA on November 8, 2002, concluded

the following regarding the hydrogeological conditions in the MPA:

• The source area is limited in extent and is centered near well CC-6;

• The core of the plume is narrow and its axis extends in a northeast direction from well CC-6 toward well GW-1;

• The groundwater plume is bounded into its narrow configuration by both physical and hydraulic features (i.e., bedding features, fault zones, etc.);

• The local hydrogeologic system functions as a porous flow system, particularly in the vicinity of the source and core plume areas. This system is characterized by highly interconnected fractured bedrock flow rather than discrete conduit flow in a karst system as suspected during the Remedial Investigation;

• A free phase or recoverable DNAPL source does not appear to be present in the area of CC-6 and CC-13';

• Natural biological attenuation of Cl-VOCs is occurring both within the source area and along the plume axis. A detailed evaluation of the biological natural attenuation processes occurring at the Site was presented in Appendix J of the PDI Report;

' Although the PDI concluded that a free-phase or recoverable DNAPL source was not present in the area of CC-6 and CC-13, it did recognize the potential presence of residual source material confined within discrete bedrock fractures.

1.3 Technology Description

Bioremediation of groundwater is a proven technology for the treatment of Cl-VOCs, such as

those identified at the Site, under the appropriate geochemical conditions. The biological

transformations of the Cl-VOCs involve anaerobic reductive dechlorination using the saturated

zone as an anaerobic bioreactor. Cl-VOCs serve as electron acceptors with simple organic carbon

compounds (e.g., sugars, alcohols, fatty acids, etc.) serving as the electron donors. Once the

anaerobic bioreactor is created and maintained, the Cl-VOCs undergo microbially-catalyzed

reductive dechlorination, which involves the sequential replacement of chlorine atoms with

hydrogen. The Cl-VOCs ultimately degrade to environmentally acceptable end-products such as

ethene, ethane, CO2, water, and chloride.

It is now well-established that microorganisms can carry out effective dechlorination of Site-

related Cl-VOCs at concentrations at or approaching the solubility limits. These microorganisms

grow towards the highest concentration of Cl-VOCs, including residual sources that may be

isolated within the primary and secondary porosity of the bedrock. The presence of increased

microbial activity at or near these residual sources can increase the mass flux of Cl-VOCs, create

steeper concentration gradients, and increase the dissolution rate. Therefore, more effective

removal of Cl-VOCs and ultimately faster cleanup times can be achieved using Bioremediation

than traditional remedies such as the groundwater extraction and treatment technology envisioned

in the 1997 ROD.

Bioremediation systems can be readily engineered to overcome uncertainty in source zone or

dimensions either by increasing the volume of electron donor or nutrient feed concentrations

and/or the number of injection points. Therefore, the technology is flexible and can be easily

adapted or expanded in the field to address unknown or changing conditions.

1.4 Microcosm Studies "

Prior to implementing the field scale Pilot Test, a laboratory microcosm treatability study was

conducted by SiREM of Guelph, Ontario, using rock cuttings and groundwater obtained from the

Site. The study was undertaken to confirm the viability of the technology at a laboratory scale

and to determine the most effective nutrients (i.e., electron donor) for field-scale application.

Groundwater and rock samples were collected during the installation of well GW-7. The

groundwater samples were then spiked to increase the concentration of trichloroethene (TCE) to

Golder Associates g:\projects\003-6000 malvern\mpa gw pilot study\january 2005 reportVpilot test report.doc AR304443

February 2005 - 4 - 003-6000

approximately 100,000 ug/L and 1,1,1-trichloroethane (TCA) to approximately 2,000 ug/L (i.e.,

representative of source conditions) prior to setting up the microcosms. Three sets of microcosms

were constructed to assess the efficacy of different electron donor types, including molasses, a

methanol-ethanol-acetate-lactate (MEAL) mix, and emulsified oil.

The three sets of microcosms were inoculated with halo-respiring microorganisms (KB-F"^

culture) to facilitate the dechlorination process. A fourth set of microcosms were not inoculated

with the KB-F'^ culture and served as an anaerobic sterile control. Halo-respiring

microorganisms possess the capability to derive energy from reductive dechlorination of Cl-

VOCs, including chlorinated ethenes such as tetrachloroethene (PCE) and TCE. To date, a

number of distinct types of halo-respiring bacteria have been identified, such as DehalospirilUum

muhivorans, Dehalobacter restrictus and Dehalococcoides ethenogenes. Dehalococcoides

ethenogenes (D. ethenogenes) are the only halo-respiring microorganisms known to contain

enzymes able to dechlorinate TCE completely to ethene. Bioaugmentation with the KB-F"^

culture, which contains several strains of Dehalococcoides, has been demonstrated to promote the

complete dechlorination of PCE and TCE to ethene (Major et al., 2002, Environmental Science

and Technology. 36:5106-5116). The KB-F"^ culture contains a mixture of naturally-occurring

(i.e., not genetically engineered) and non-pathogenic microorganisms. KB-l"™ has been

extensively tested to ensure the absence of known pathogenic microorganisms such as:

Salmonella sp.. Listeria monocytogenes. Vibrio sp., Campylobacter sp., hemolytic Clostridia sp.,

Pseudomonas aeruginosa. Yersinia sp., Candida albicans, Aspergillus fumigatus, fecal coliforms

and Enterococci, Bacillus anthracis. Bioaugmentation with KB-P"^ has been used, or has been

approved for injection at a number of USEPA Superfiind Sites, Federal Sites, and industrial sites,

including three in USEPA Region HI.

The microcosm study was initiated on May 7, 2003, and was sampled on a regular basis through

February 20, 2004. Figures 3 and 4 show the averaged replicate data for the MEAL and molasses

amended microcosms, respectively^. The data indicates very similar performance between the

MEAL and molasses amended microcosms, with TCE conversion to cis-1,2-dichloroethene (cis-

DCE) occurring beginning between 23 and 30 days, and vinyl chloride (VC) production

beginning between 212 and 247 days. The rapid decrease in cis-DCE and increase in VC

production coincided with a substantial decrease in TCA concentrations to approximately 1,000

The emulsified oil, did not begin to degrade TCE until approximately 107 days, and therefore was not considered for use in the field pilot.

Golder Associates g.\projects\003-6000 malvern\mpa gw pilot study\january 2005 report\pilot test report.doc AR304444

February 2005 - 5 - 003-6000

ug/L. TCA has been shown in some cases to have a somewhat inhibitory effect on the reduction

of Cl-VOCs, particularly, the reduction of cis-DCE (Duhamel et al., 2002), However, as the

natural biomass grows, it facilitates the reduction of TCA, and cis-DCE is rapidly dechlorinated.

These microcosm results are consistent with other studies at sites with mixed chlorinated ethenes

and ethanes and are consistent with the relative energy yields of these compounds (Fihn et al.,

2003). VC production in the molasses microcosms leveled off after 290 days, whereas VC

production was still increasing at the end of the microcosm study (350 days) in the MEAL

microcosms. Minor amounts of ethene were produced after 260 days in the molasses

microcosms, and after 340 days in the MEAL microcosm. By comparison, cis-DCE was riot

produced for the duration of the microcosm study in the anaerobic sterile control.

The microcosm study confirmed the ability of Bioremediation to completely degrade Cl-VOCs

from TCE to VC in Site groundwater at a laboratory scale. MEAL was ultimately selected as the

electron donor solution for the field scale pilot. Its use allows the added flexibility of varying the

amounts of the individual nutrients to stimulate the activity of different indigenous microbes. An

initial electron donor solution of 2:3:1 Methanol:Ethanol:Lactate was selected with a total

concentration of 600 mg/L. It was also determined that the grouncdwater would be inoculated

with KB-F'^ culture as part of the field Pilot Test, to promote complete degradation of Cl-VOCs.

2.0 FIELD PILOT TEST INSTALLATION

2.1 Pilot Test Layout

The Pilot Test layout included 8 wells, as shown on Figure 2. Construction activities related to

the field Pilot Test were initiated on March 18, 2003, with the installation of monitoring well

GW-6 and groundwater injection well GW-7. Construction details for wells in the MPA are

provided in Table 1. Following installation of the wells, underground piping and above ground

structures were installed. The work was completed in June 2003.

The electron donor injection system consists of the following:

• One 2,000-gallon poly tank for storage of groundwater extracted from CC-7 and used for injection at GW-7 and dispersion of the electron donor;

• Inert gas system connected to the groundwater storage tank to minimize contact with oxygen;

• 50 gallon nutrient mix tank;

• Electron donor and groundwater feed metering systems;

• Control panel, shut-off switches, and timers; and,

• Heat, heat tracing electric, and ventilation (as required).

The electron donor system is housed in a pre-fabricated wooden shed located along the eastern

fence line of the MPA adjacent to CC-6 and CC-7. Groundwater is extracted from well CC-7

using a submersible pump and is transferred to the treatment building via underground piping.

Groundwater is then pumped to the injection well (GW-7) using a batch metering pump. Electron

donor from the 50-gallon nutrient tank is batch fed into the groundwater discharge piping using

another batch metering pump.

2.2 Geology and Hydrogeology

In general, the subsurface conditions encountered during the drilling of the two new wells

confirmed the previous geologic and hydrogeologic model for the Site. Bedrock is encountered

at a depth of between 16 and 85 feet below ground surface and consists of a light to, medium grey,

finely to coarsely crystalline dolomite of the Ledger Formation. Overburden soils generally

consist of fine-grained, reddish-brown silt with varying amounts of clay.

Golder Associates g:\projects\003-6000 malvemVmpa gw pilot study\january 2005 reportVpilot test report.doc AR304446

February 2005 - 7 - 003-6000

TROLL pressure transducers/data loggers were installed in existing adjacent monitoring wells to

evaluate the hydraulic continuity of the aquifer within the Pilot Test area during drilling. Pressure

response graphs are shown on Figures 5 and 6. As illustrated in the graphs, pressure responses

were observed in all of the wells monitored, suggesting that there is good hydraulic

communication across the Pilot Test area. It was also noted, however, that subsequent monitoring

data collected from well GW-6 does not support a strong hydraulic connection between this well

and injection well GW-7. This is presented in fiirther detail in the following sections.

Table 2 presents a summary of water levels measured during the Pilot Study. Figures 7 and 8 are

groundwater contour maps based on data collected on April 15, 2004, and October 12, 2004,

respectively. The groundwater flow directions depicted in Figures 7 and 8 are consistent with

those observed during the PDI. The average horizontal hydraulic gradient calculated for these

events is 1.7x10"' feet per foot, which is also consistent with the average horizontal gradient

calculated during the PDI (Golder Associates, 2003b).

Rainfall events impacted groundwater elevations in the MPA during the Pilot Test as shown on

Figure 9, and at the initiation of the Pilot Test, groundwater elevations were at the highest levels

observed at the Site since the start of the PDI, in 2000. As discussed in Section 3.2, increased

precipitation frequency also appeared to inhibit the development of an anaerobic treatment zone

during the initial stages of the Pilot Test and caused variability in Cl-VOC concentrations in the

source area.

Rising head slug tests were conducted in wells GW-6 and GW-7 prior to the initiation of the Pilot

Test. The hydraulic conductivity values calculated for wells GW-6 and GW-7 from these tests are

1.5x10' centimeters per second (cm/sec) (4.3 feet per day [ft/day]) and 1.0x10' cm/sec (2.84

ft/day), respectively. These values are consistent with the average hydraulic conductivity value

calculated for the other MPA wells monitored during the PDI (2.3x10'''cm/sec [6.5 ft/day]).

2.3 Tracer Testing

To further assess groundwater velocity and hydraulic continuity between wells in the Pilot Test

zone, a potassium bromide tracer test was conducted in January 2004. Bromide solution was

injected at GW-7 and monitored at wells CC-6 and GW-6. The concentration of the bromide

solution, the injected solution volume, the mass of bromide, and the date of the bromide release

for each injection well is summarized in Table 3. For all the tests, the bromide solution injection

Golder Associates g:\projects\003-6000 malvem\mpa gw pilot study\january 2005 report\pilot test report.doc AR304447

February 2005 - 8 - 003-6000

was followed by the injection of potable water. The bromide solution arrival was monitored

using an electronic data logger with transducers calibrated on-site to bromide calibration

standards.

The results of the tracer study are shown on Figure 11. The main concentration of bromide

arrived at well CC-6 approximately eight days after injection at GW-7. This corresponds to a

groundwater velocity of approximately 2.7 feet per day. By comparison, the calculated

groundwater velocity using the average horizontal hydraulic gradient measured between well

GW-7 and CC-6, and an average hydraulic conductivity for the two wells (i.e., 5.7 ft/day), yields

an advective groundwater velocity of 2.9 ft/day. Although bromide-specific probes were not

deployed at downgradient well GW-1, subsequent monitoring data indicates a strong hydraulic

connection between this well, well CC-6 and well GW-7. Alternatively, the lack of a bromide

response in conjunction with subsequent monitoring data at well GW-6 indicates that,

hydraulically, this well is poorly connected to the injection well GW-7.

3.0 PILOT TEST IMPLEMENTATION

3.1 Groundwater Sampling

Groundwater samples were collected and analyzed using two different methods. The first method

involved laboratory analysis using approved EPA-methods including the collection and analysis

of QA/QC samples for TCL VOCs and natural attenuation parameters (NAPs) as described in the

PDI Sampling and Analysis Plan (SAP) and SAP Addendum (presented in the Work Plan). This

work was performed by CompuChem Labs of Gary North Carolina. The second method, referred

to as screening level analysis was undertaken by SiREM's laboratory, and included analysis of

VOCs, light hydrocarbon gases and major cations/anions, as described in the SAP Addendum. In

addition to monitoring for changes in Cl- VOC concentrations, these additional data were

collected to evaluate the presence of competing electron acceptors (such as nitrate, sulfate, iron

and manganese) and end products of microbial reductive dechlorination processes (such as ethene

and ethane).

The first method was used during the baseline sampling event, as well as the December 2004

event (i.e., the last event reported) to calibrate or confirm the field screening results, which were

collected on a more frequent basis to monitor trends in the data. Laboratory data was validated in

accordance with the SAP and SAP Addendum. During the December 2004 QA/QC sampling

event, samples were also collected at wells GW-1, CC-6 and GW-7 for confirmatory screening

level analysis. Table 4 presents a comparison of these data and indicates that there is good

agreement between the two analytical methods, supporting the use of the screening level results

in the evaluation of data trends established during the Pilot Test and the use of this technique in

future data collection efforts.

3.2 Nutrient Addition and Bioaugmentation

3.2.1 Nutrient Addition

Aquifer conditioning was initiated on December 22, 2003 to establish geochemical conditions

optimal for the growth of the KB-1^^ culture. It continued for a period of five weeks prior to the

introduction of KB-F'** and following inoculation of the system as described below. Groundwater

was injected in GW-7 at a rate of 0.2 gpm, and electron donor (methanol, ethanol and lactate) was

added on a constant basis. This injection scheme was continued until September 2004 when daily

batch injections were initiated because suitable geochemical conditions could not be maintained

in the treatment zone during the Spring and Summer months. During these months, above average

rainfall frequencies impacted the maintenance of anaerobic conditions in the treatment zone and

caused an increase in Cl-VOC mass loading in the groundwater. Daily batches of electron donor

with dibasic ammonium phosphate were injected beginning in September 2004 to counteract and

buffer these effects^. As presented in Section 4, these modifications have facilitated the

establishment of a robust and stable biomass that is more resistive to these seasonal "shocks".

3.2.2 Bioaugmentation

At the end of the initial five week aquifer conditioning period, groundwater geochemical

parameters at CC-6 (i.e., dissolved oxygen and redox potential) indicated that the aquifer had

been suitably prepared for the injection of KB-F"^. Bioaugmentation was completed on January

29, 2004, with the injection of a total of lOOL of KB-l™ inocculum into well GW-7. A second

bioaugmentation followed the, September 2004 batch nutrient additions when an additional 40L of

KB-ITM was injected into well GW-7, and lOL each of KB-F*^ was injected into wells GW-1 and

CC-6.

Dibasic ammonium phosphate was used to achieve a carbon:nitrogen: phosphorous ratio between 10:1:0.1 to 20:1:1.1

4.0 PILOT TEST RESULTS

4.1 General

The objective of the Pilot Test was to demonstrate under field conditions that a Bioremediation

treatment zone could be established and maintained, which could completely degrade Cl-VOCs in

Site groundwater, confirming the results of the laboratory microcosm studies. As discussed in

preceding sections, establishing the Bioremediation treatment zone included both the

development of the indigenous or native biomass as well as the KB-F** culture.

4.2 Degradation Thermodynamics

In evaluating groundwater data from the Pilot Test, it is important to understand the general

thermodynamics associated with the degradation of Cl-VOCs. Theoretical energy yields'*

associated with reduction of each compound provides the best insight into the relative decay rates

and the anticipated timing for the various transformations. The following table (based on deBest,

1999), details the energy release associated with each reduction reacfion:

Compounds such as PCE, TCE, TCA, and chloroform are preferentially degraded over

compounds such as cis-DCE, due to their higher energy yields. As a result, cis-DCE and other

lower energy yielding compounds tend to persist until the higher energy compounds are depleted.

Similarly, since the energy yield of VC is significantly higher than cis-DCE, it degrades rapidly

upon conversion and hence the observance of elevated levels of VC on a sustained basis is

unlikely.

Energy yield is not the only consideration in determining degradation patterns, but is instructive in the present case.


AR304451

February 2005 - 1 2 - 003-6000

Therefore, it is expected that the VOCs in groundwater will degrade in a sequential manner with

substantial depletion of the parent compounds PCE and TCE occurring prior to more substantial

degradation of daughter products such as cis-DCE. This is consistent with the trends noted in the

microcosm studies. An evaluation of the groundwater sampling results, with respect to the

production of daughter products, is presented below.

4.3 Groundwater Sampling Results

Development of a Bioremediation treatment zone is evidenced by geochemical indicators of an

anaerobic environment, by the presence of dehalogenating microorganisms in the downgradient

wells, and by an increasing ratio of daughter to parent compounds.

For the purpose of the following evaluation, wells GW-6 and CC-3 provide a background

comparison. The results of the tracer study, in conjunction with the sampling results, indicate that

well GW-6 is, hydraulically, poorly connected to well GW-7, or not within the current treatment

zone. Well CC-3 is upgradient of the treatment zone (Figure 2).

4.3.1 Geochemical Conditions

Geochemical parameters are presented on Figures 11 through 16, while major cations are

presented on Figures 17 through 24. A summary of key conclusions is provided below:

• Dissolved oxygen levels have been maintained at near zero levels at, and downgradient of the source area (i.e., wells CC-6 and GW-1), and in the injection well. Control wells CC-3 and GW-6 indicate that background DO levels are generally stable and range in concentration from 2 mg/L at CC-3 to 5 mg/L at GW-6.

• Negative redox potentials have generally been maintained for the duration of the pilot study in wells CC-6 and GW-7, and have been strongly negative at well GW-1 since November 2004. Alternatively, background wells CC-3 and GW-6 indicate positive redox potentials ranging from 50 mV to 100 mV.

• Reductions in sulfate concentration are clearly observed at CC-6 from an initial concentration at the beginning of the pilot test of 8 mg/L to a current concentration of less then 1 mg/L. While the overall reduction is not as great at GW-1, the current concentrations are about one third of their original concentrations, and show a downward trend in concentration. By comparison, the sulfate concentrations in the control wells, CC-3 and GW-6, exhibit an increasing trend over the course of the Pilot Test.

• Increased levels of Biological Oxygen Demand (BOD) also indicate the effectiveness of the distribution of nutrients throughout the treatment zone. BOD levels are highest at wells CC-6, GW-1 and the injection well GW-7, while BOD levels in the background wells are at or below detection levels.

February 2005 - 13 - 003-6000

All of the above geochemical trends are consistent with the sustained occurrence of biologically

mediated reductive dechlorination.

4.3.2 Degradation of Chlorinated Volatile Organic Compounds

The groundwater results indicate that chlorinated ethenes are being degraded at an accelerated

rate in the Bioremediation treatment zone, both within and downgradient of the source area, as

evidenced at wells CC-6 and GW-1, respectively.

Figures 25 through 32 present XY graphs of chlorinated ethene concentration versus time on a

well-by-well basis. These figures are useful for illustrating absolute changes in concentration;

however, it can be difficult to discern the effects of Bioremediation using these graphs alone. In

particular, natural variability in the groundwater concentrations, as well as additional contaminant

loading into the aquifer from residual source mass in the aquifer matrix can mask these effects.

This was evident at well CC-6.

A more useful tool for assessing the rate of degradation or other data trends is to plot the

chlorinated ethenes as normalized ratios. Normalized ratio plots were produced for each of the

wells by plotting the individual chlorinated ethene compounds, expressed as a percentage of the

total concentration of chlorinated ethenes. These plots are shown on Figiiries 32 through 40. A

review of these figures yields the following observations:

• Conversion of PCE and TCE ultimately to cis-DCE has been strongly facilitated,in the treatment zone at wells CC-6 and GW-1. It is very clear from the normalized ratio plots that the relative proportion of cis-DCE compared to TCE and PCE has increased dramatically in these wells since the beginning of the pilot study. Figures 33 and 34 show that, initially, cis-DCE generally comprised less than 10% of the chlorinated ethenes prior to the April 2004 sampling event. This percentage is consistent between the PDI data (2001), the baseline sampling (2003) and the initial rounds of the pilot test. At both wells, cis-DCE increased steadily to almost 80% by November 2004. In comparison, the background wells showed virtually no increase in the amount of cis-DCE, suggesting that this trend is clearly the result of microbial reductive dechlorination processes.

• Low concentrations of VC and ethene are currently observed in wells GW-1 and CC-6, providing evidence that the necessary microorganisms are in place to achieve cornplete dechlorinafion of Cl-VOCs.

• The current data indicates that concentrations of cis-DCE may have leveled off or started to decrease at well GW-1. This, in conjuncfion with the noted temporary increases in VC and ethene, suggests that cis-DCE is now being degraded and provides additional

AR304453

February 2005 - 1 4 - 003-6000

evidence that the necessary microorganisms are in place to achieve complete dechlorination of Cl-VOCs.

• In addition to the more substantial trends observed in the treatment zone at wells GW-1 and CC-6, other wells exhibited lesser increases in their rates of cis-DCE production. There appears to be a sharp increase in the rate of cis-DCE production (from about 10% cis-DCE to 25% cis-DCE) at well CC-13, the deep source area well adjacent to well CC-6, beginning in September. A similar increase in the production of cis-DCE is also

^ observed at well CC-21, which is located off the main axis of the plume, and therefore is situated on the margin of the Bioremediation treatment zone.

• Concentrations of Cl-VOCs in background wells CC-3 and GW-6 were generally stable throughout the Pilot Test indicating that the trends noted above are the result of the development of the Bioremediation treatment zone, rather than sampling variability.

4.3.3 Additional Observations

In addition to chlorinated ethenes, chlorinated ethanes, and chlorinated methanes (e.g., TCA and

chloroform, respectively), are present in Site groundwater. These two groups of compounds

degrade in similar step-wise manners under the same geochemical conditions as the chlorinated

ethanes, ultimately resulting in the production of harmless end-products, specifically ethane and

methane.

Figures 41 and 48 provide XY plots of concentration versus time for the chlorinated ethanes. As

can be seen from these graphs, TCA concentrations increased in the treatment zone at well CC-6

(Figure 42). Comparatively, TCA concentrations remained relatively stable in the background

wells and well GW-1 (Figure 41). This trend has been observed in conjuncfion with

Bioremediation at other sites, and is concluded to be the result of mole fractionation. Specifically,

TCA solubility from residual source mass increases with the removal of TCE from the source

resulting in increasing concentrations of TCA in the dissolved phase immediately adjacent to the

source area (Finn et al. 2003). Similarly, chloroform concentrations have increased somewhat at

well CC-6 while remaining relatively stable at well GW-1 and control wells GW-6 and CC-3.

While the variability in source area concentrations make it difficult to assess the degree to which

mole fractionation may be responsible for the TCA and chloroform trends observed at CC-6, it is

reasonable to conclude that this process may be a contributing factor.

Groundwater extraction at well CC-7 does not appear to be unduly influencing the groundwater

flow directions in the treatment zone as little to no increase in the rate of conversion of TCE to


February 2005 - 1 5 - 003-6000

cis-DCE was observed at this location. These results are consistent with the model predictions

presented as part of the Pilot Study Work Plan.

Well GW-7 shows a very similar geochemical signature to well CC-7, and indicates that cis-DCE

generally comprises 30%) to 45%i of the total chlorinated ethenes. As groundwater is constantly

injected at a rate of 0.2 gpm, it is not expected that significant TCE degradation would be

observed at this location because the well is constantly being recharged with water from well CC-

7, which lies outside of the treatment zone. This provides further evidence that the degradation

observed at wells CC-6 and GW-1 is the result of enhanced biological activity.

4.4 Measured Field Half-Lives

An analytical degradation model was used to estimate the half-lives of PCE and TCE at

monitoring well GW-1. This analysis was completed for GW-1 as this well clearly showed the

effects of accelerated biologically mediated reductive dechlorination, and was not subject to

source zone variability that was seen at well CC-6. The spreadsheet-based model uses a

formulation based on first order decay kinetics, with the additional contribution of the decay of

the parent compound included. The basic formulation is as follows:

Cn„ = [C„„., + e(C ,M - C„„,)]exp(-;i„At) (1)

where: Cn = concentration of compound n (daughter) (|J.g/L); Cm = concentration of compound m (parent) (^.g/L); t, t-1 = current and previous time step (years); At = time step value (years); e = (molecular weight of compound n)/(molecular weight of compound m); and, Xn = decay constant of compound n (year'').

For PCE, the uppermost parent compound, equation (1) reduces to C„,, = Cn,t.i exp(-Ât). The

model solves equafion (1) simultaneously for PCE and TCE.

Figure 49,shows the results of this estimation and indicates that the half lives for PCE and TCE

are 100 and 110 days, respectively at well GW-1. While these half lives are not as short as the

microcosm data would tend to suggest, typical literature values for PCE half-lives range fi-om

about 300 days to 720 days, and for TCE, half-lives range from about 300 days to 1600 days.

Clearly the estimated half-lives for these two compounds have been shortened in response to the

AR304455

February 2005 - 1 6 - 003-6000

development of the downgradient treatment zone. As the Bioremediation system continues to

develop, the half-lives measured from the field data are expected to decrease further.

4.5 Summary

In summary, the results of the Pilot Test indicate that accelerated biological treatment appears to

be an effective alternative for addressing groundwater impacts at and downgradient of the source

area. Electron donor injections at well GW-7, which is believed to be located just upgradient of

the residual source zone, have been successful in establishing and maintaining a zone of

accelerated biological treatment (i.e., reductive dechlorination) of chlorinated ethenes! The

treatment zone extends a significant distance to, and likely downgradient, from well GW-I.

Vinyl chloride and ethene detections at GW-1, in conjunction with a leveling off or decrease in

cis-DCE concentrations indicate that the treatment zone is capable of complete dechlorination. In

addition to these favorable results at GW-1, significant treatment of the source zone is being

achieved at CC-6 as evidenced by increases in TCA and, to a lesser extent, chloroform

concentrations, which are believed to be, in part, the result of mole fractionation caused by a

depletion in residual PCE and TCE mass in this area. The depletion of residual material is

anticipated to continue, eventually resulting in similar degradation trends in CC-6 as are currently

observed at GW-1.

The results obtained to date are consistent with the microcosm results in that cis-DCE is

persisting in the presence of TCA. Slight increases in the TCA concentration in the source area

are anticipated to continue temporarily as the reduction in TCE and PCE causes more dissolution

of the TCA into the groundwater. Once sufficient biomass is present, Bioremediation of TCA

(and associated daughter products) and chloroform will be accelerated. As a result, TCA and

chloroform concentrations will stabilize and subsequently decrease throughout the treatment

zone. Once TCA concentrations approach 1 mg/L, rapid dechlorination of cis-DCE is anticipated

to occur, similar to what was observed in the microcosms, as well as what has been reported for

other sites. Rapid dechlorination of cis-DCE did not occur in the microcosm study until after

approximately seven months and likewise, since the treatment zone was not fully established until

September 2004, the earliest that this might be anticipated to occur in the field would be March or

April of 2005. However, given that the microcosms are kept at considerably higher temperatures

than the in-situ temperature within the aquifer, these dates would be considered the earliest at

which results in the field might be observed.

The results also indicate that treatment can be established and maintained in the residual source

zone and that the treatment zone at CC-6 is capable of assimilating increases in concentration as a

result of groundwater flushing residual source mass from the aquifer matrix. The more recent data

indicates that an increasing level of bioactivity is occurring throughout the treatment zone and

that the biomass is sufficiently established so that the system is effectively buffered from

potential ftiture seasonal shocks. In addition, capping of the MPA will also help to minimize

localized seasonal groundwater level fluctuations.

5.0 FUTURE ACTFVITIES

5.1 Development of Final Design Parameters

Given these favorable data trends, the CSDG believes that Bioremediation, in conjunction with

natural attenuation, will provide for the most effective and timely remediation of groundwater

impacts in the MPA, including residual sources in the area of CC-6. The CSDG proposes to

continue to operate and optimize performance of the system for an estimated six (6) month period

of time and collect additional information necessary to develop a final remedial design. This will

provide continued active treatment of the plume and residual source mass, while allowing the

CSDG and the USEPA to verify the above conclusions, particularly with regard to the fiming of

these later developing trends (i.e., more pronounced degradation of cis-DCE and TCA and

corresponding production of ethene and ethane). It will also allow for the collection of additional

data which is critical to the design of a final groundwater remedy. Based on the results of the

microcosm study, the duration of this extended confirmation monitoring period is estimated to be

four to six months.

In addition to confirming and understanding the timing of the above trends and pending USEPA

approval, the pre-design studies will also include:

• Expansion of the injection system and treatment zone to include the entire source zone and well GW-6 in the final system design; and

• Development of design parameters including the injection well spacing, nutrient source, monitoring network and automated delivery system for fiill scale operation.

5.1.1 Confirmation of Groundwater Trends

Operation of the electron donor injection system will initially be maintained in its current

configuration in order to further support the timing of the data trends and conclusions presented

in this report. During this period of continued operation, screening level groundwater samples

will be collected from a reduced number of monitoring wells on a bi-weekly basis initially. This

frequency may be modified pending the results and the observed changes in concentration. At a

minimum, this additional data collection would be undertaken at the key monitoring wells (i.e.,

GW-7, CC-6, GW-1 and CC-13). During this period the CSDG will confinue to evaluate and

refine the nutrient mix to optimize performance. Once the initial period of operation has been

completed and evaluated, and pending USEPA approval, the next steps in implementation of the

final groundwater rernedy, as outlined below, will be undertaken

AR304458

February 2005 -19 - 003-6000

5.1.2 Collection of Additional Design Parameters

Once the above trends are established, addifional data will be collected to facilitate design of a

final system. This will include characterizing the hydraulic connection between GW-6 and the

source area so that the final treatment zone encompasses both the source zone and this well,

which has not been influenced by nutrient injections at well GW-7. This may require the

installation of an additional injection well to the north of well CC-6 followed by the completion

of a tracer study to assess hydraulic interconnections in this part of the site.

Other parameters may also need to be refined in order to design and implement the final remedial

system including:

• Optimizing the current electron donor amendments, (i.e., evaluating variations in the proportions of the individual amendments or other altemafive amendments);

• Refining the delivery of nutrients (i.e., changes in the nutrient delivery frequency or duration, as well as the ability to automatically batch-feed non-liquid amendments, such as dibasic ammonium phosphate); and

• Evaluating alternative injection strategies (i.e., nufrient injections directly into the source well CC-6, or other wells within the treatment zone).

To collect this data, additional modifications to the system may be proposed during this operating

period. These modifications will be detailed in a letter Plan(s) that will be submitted for approval

by the USEPA.

5.2 Reporting

During the initial operating period, the CSDG will provide monthly updates to the USEPA.

These updates are anticipated to include addifional groundwater monitoring results and trend

analyses. In addition, the CSDG will submit for EPA approval any proposed changes in the

monitoring or operation of the system, and will submit a letter Plan(s) detailing the additional

proposed work discussed above, prior to its unplementation.

ANALYTICAL DATA EVALUATION

Introduction

On behalf of the Chemclene Site Defense Group, Golder Associates Inc. (Golder Associates)

evaluated the analytical data for the groundwater samples collected April 29 and April 30, 2003 at

the Malvern TCE Superfiind Site as part of the Main Plant Area (MPA) Groundwater Pilot Study.

These samples were collected in accordance with the Sampling and Analysis Plan (Field Sampling

Plan and Quality Assurance Project Plan), Appendix A of the Remedial Design Work Plan (RDWP)

for the Pre-Design Investigation (PDI), dated May 2000 (and the response to USEPA comments

dated August and October 2000) and the SAP Addendum, dated December 2002. The samples

collected and the parameters analyzed are summarized in Table Al-1.

The samples were submitted to CompuChem (Laboratory), in Cary, North Carolina via overnight

courier. The laboratory personnel receiving the samples placed them in Sample Delivery Group

(SDG) A1904. The samples were analyzed for Target Compound List (TCL) Volatile Organic

Compounds (VOCs), using the TCL from the Contract Laboratory Program (CLP) Statement of

Work OLM03.2. In addition, the samples were analyzed for the following Natural Attenuation

Parameters (NAPs): alkalinity, chloride, total iron, total mangansese,, nitrate, nitrite, total

phosphorus, sulfate, sulfide, Total Dissolved Solids (TDS), Total Organic Carbon (TOC), and

methane, ethane and ethene (MEE). CompuChem performed all of the analyses except methane,

ethane and ethene, which were analyzed by Microseeps of Pittsburgh, PA.

Samples for VOCs were analyzed using Method 8260B - Volatile Organic Compounds by Gas

Chromatography/Mass Spectrometry (GC/MS) (December 1996) from Test Methods for Evaluating

Solid Waste, Physical/Chemical Methods, EPA SW-846, Third Edition, as amended by Updates I,

n, UB, and III, (fmalized in the Federal Register June 1997) (SW-846). The NAPs were analyzed

by various methods detailed in SW-846 and in Methods for Chemical Analysis of Water and

Wastes, EPA 600/479-020 (March 1983). Specifically, total iron and total manganese were

analyzed by SW-846 Method 60I0B - Inductively Coupled Plasma-Atomic Emission Spectrometry

(December 1996). MEE was analyzed by Microseeps laboratory-specific procedures AMI8 and

AM20GAX.

Data evaluation was performed to prevent erroneous or otherwise unusable data from entering the

project record. Evaluation was performed on 100% of the data submitted by .the Laboratory.

Evaluation for organic data was performed in accordance with the USEPA Region III Modifications

to National Functional Guidelines for Organic Data Review Multi-Media, Multi-Concentration

(OLMO1.0-OLMO1.9), (September 1994) snA Innovative Approaches to Data Validation, USEPA

Region III, (June 1995). Evaluation of the metals data was performed in accordance with USEPA

Region III Modifications to the Laboratory Data Validation Functional Guidelines for Evaluating

Inorganics Analyses, (April 1993). Hereafter, these documents are referred to as "the functional

guidelines". The samples were analyzed by SW-846 methodology, rather than the CLP methods

referenced by the functional guidelines. Therefore, the functional guidelines provided only

general guidance for the evaluation of the validity of the analytical data generated by the

Laboratory. Where there was a conflict between the functional guidelines and the analytical

methodology, method-specific criteria and professional judgment were used. The NAPs were

evaluated in accordance with the method-specific criteria.

Following data evaluation and qualification, the analytical data and qualifiers for each sample point

were summarized. Qualified results are provided in a tabular format in Appendix B-1. Data

qualifiers and definitions are presented in Table Al-2.

TCL Volatile Organic Compounds

Eight primary samples, one field duplicate, one rinsate blank and one trip blank were collected for

VOC analysis. Data for VOCs were evaluated based upon completeness, technical holding times,

field and laboratory blanks and precision and accuracy results. Precision results include field and

laboratory duplicates and duplicate analyses of Matrix Spikes; accuracy results include surrogate

spikes. Matrix Spike/Matrix Spike Duplicates and Laboratory Confrol Samples. Additionally, the

identification and quantification of detected compounds were confirmed by a review of the

chromatograms, mass specfra and data system printouts (quant reports).

The only data quality issue identified was blank contamination with the common laboratory

contaminants methylene chloride and toluene. An action level of 10 times the concenfration found

in the blanks was calculated. In accordance with the fianctional guidelines, samples with

detections for these analytes below the action level were qualified (B) to indicate that the results are

probably due to -field or laboratory contamination. The TCL VOC data qualifier summary is shown

in Table A1-3.


AR304518

January 2005 Al-3 003-6000

Natural Attenuation Parameters

Eight primary samples, one field duplicate and one rinsate blank were collected for NAP analysis.

Data for NAPs were evaluated based upon completeness, technical holding times, field and

laboratory blanks and precision and accuracy results. Precision results include field and laboratory

duplicates and duplicate analyses of Matrix Spikes; accuracy results include Matrix Spike/Matrix

Spike Duplicates and Laboratory Control Samples.

The functional guidelines require that samples for nitrate and nitrite are analyzed within two (2)

days of collection. Two samples were analyzed outside of this holding time. The nifrate and nitrite

results for these samples were qualified as estimated (J) or the reporting limit was qualified as

estimated (UJ) for non-detected results in accordance with the functional guidelines.

Sulfide was seen in the rinsate blank associated with the project samples. An action limit of 5 times

the concentration seen in the blank was calculated. In accordance with the functional guidelines,

samples with detections for sulfide below the action level were qualified (B) to indicate that the

results are probably due to field or laboratory contamination. The conventional parameters data

quality summary is presented in Table Al-4.

Summary

Evaluation of the data collected for the MPA Groundwater Pilot Study at the Malvern TCE Site was

conducted in accordance with USEPA Region HI data evaluation guidelines, as applicable, and the

criteria specified by the specific methods and the RDWP and associated amendments. ''

Overall, the data required qualification due to some quality control criteria which were not

achieved, but the majority of the data is deemed usable in terms of objectives of the MPA

Groundwater Pilot Study. If a positive result was qualified as estimated, the analyte should be

considered present. Similarly, a non-detected result which was qualified as an estimated

quantitation/detection limit should be considered not present for the purposes of this study, although

the limit itself may not be precise.
