Subject: Underground Injection Control (UIC) Permit Application for Enhanced
In Situ Bioremediation (EISB) Pilot Testing
Chemtronics Site,
Swannanoa, Buncombe County,
North Carolina
Dear Mr. Slusser:
Geosyntec` Consultants of NC, P.C. (Geosyntec) has prepared the attached Underground
Injection Control (UIC) permit application for the Chemtronics Site located in Swannanoa,
Buncombe County, North Carolina (the Site). Geosyntec has prepared this application on behalf
of Chemtronics, Inc., Northrop Grumman Systems Corporation (Northrop Grumman), and CNA
Holdings LLC (CNA) (together the Companies). Enhanced In Situ Bioremediation (EISB) pilot
tests, as described in.this permit application, .are planned at the Site in support of the Remedial
Investigation/Feasibility Study (RI/FS) currently being completed under the Comprehensive
Environmental Response, Compensation, and Liability Act (CERCLA) program (EPA CERCLIS
ID: NCD095459392).
Ms. Elizabeth A. Hartzell of the Superfund Section, Division of Waste Management (DWM) in
the North Carolina Department of Environmental and Natural Resources (NCDENR) has
provided a letter under separate cover to certify that cleanup activities at the Site are being
conducted under the CERCLA program. As summarized by Ms. Hartzell, the Companies
request a Letter of Consent, as opposed to a Class 51UIC Permit, for the proposed pilot tests per
N.C.G.S. 130A.310 (e).
Groundwater compounds of potential concern (COPCs) at the Site include volatile organic
compounds (VOCs), nitroaromatics, and energetics (perchlorate). EISB was identified during
feasibility screening of candidate technologies as a promising remedial technology given Site
conditions (i.e., COPC mixtures and distribution, groundwater geochemistry, hydrogeology,

etc.). Three EISB pilot tests, which are the subject of this UIC permit application, are proposed
to generate design and performance data to support the eventual selection of appropriate
technologies for source mass reduction and/or plume migration control within key areas of the
Site.
EISB is accomplished by stimulating microbial degradation through the injection of a
biodegradable organic carbon source. (electron donor) and/or amendment of a bioaugmentation
culture. The EISB pilot tests will consist of injecting a biodegradable emulsified vegetable oil
(EVO) (Newman Zone®, an EVO product that also includes 4% sodiumlactate) solution into a
total of 36 permanent injection wells. For two of the pilot tests, a bioaugmentation culture (KB-
1® Plus, which is a mixture of KB-1® and WBC-2 bioaugmentation cultures) and buffer will also
be injected. Potable water will be used to provide additional water for dilution and injection of
the EVO solution. Another electron donor, EHCO, will be used to generate anaerobic conditions
in the injection fluid prior to injection. Implementation of EISB utilizing EVO as a carbon
source/electron donor and a bioaugmentation culture is a safe and environmentally sound
remediation technology that is widely practiced. The planned injectants are on the UIC
Program's list of approved injectants. Specific details of the injection fluid composition,
injection rationale and procedure, and proposed monitoring plan are provided in the attached
UIC application. The pilot tests are evaluating an in situ remedy; as such, contaminated
groundwater will not be extracted, treated ex situ, and then re -injected into the aquifer.
Geosyntec looks forward to working with the Division of Water Quality during their review of
the UIC permit application. If you have any questions regarding the Site, the proposed EISB
pilot tests, or the attached application, please do not hesitate to contact the undersigned.

ATTACHMENT I
INJECTION ZONE

1. INJECTION ZONE
1.1 Overview
The Chemtronics Site (Site) is located in Swannanoa, Buncombe County, North Carolina and is
divided into two geographic areas commonly referred to as the Front Valley and Back Valley
(see. Figure 9-1 of Attachment 9). Enhanced In Situ Bioremediation (EISB) has been identified
as the candidate technology with the broadest applicability to the Front Valley groundwater -
Areas of Concern (ADCs), and the most likely to have remedial success given. the Front Valley
conditions (i.e., Compounds of Potential Concern [COPC] mixtures and distribution,
groundwater geochemistry, hydrogeology, etc.). Site COPCs include volatile organic
compounds (VOCs), nitroaromatics, and energetics (perchlorate), whose concentrations in
groundwater exceed applicable Federal and State standards.
Pilot tests are planned in support of the Remedial Investigation/Feasibility Study (RI/FS)
currently being completed under the Comprehensive Environmental Response, Compensation,
and Liability Act (CERLCA) program (EPA CERCLIS ID: NCD095459392). The proposed
injection activities will be evaluated per the monitoring plan described in Attachment 7. The
pilot tests are intended to confirm the ability of EISB to effectively degrade the target COPCs to
appropriate end products under actual field conditions. The pilot tests will also be used to
generate design and performance data for potential scale -up of the EISB technology at these pilot
test areas (PTAs).
EISB pilot tests are planned at three areas within the Front Valley including: the Building 105-
139 Area (B105-139), Building 147 Area (B147) and Building 149 Area (B149). -The locations
of these PTAs are shown in Figures 9-2 and 9-3 of Attachment 9. The pilot tests will be
conducted to evaluate the efficacy of treating the following COPCs using EISB:
• Groundwater Area B105-139 — Elevated concentrations of chlorinated volatile organic
compounds (cVOCs), particularly trichloroethene (TCE; up to 23,000 micrograms per
liter [µg/L]), in Zone AB1;
• Groundwater Area B147 — Perchlorate (up to 480 µg/L); and
• Groundwater. Area B149 = TCE (up to 350 µg/L) in the partially weathered rock in
Zone C.
The following subsections describe the horizontal and vertical portion of the subsurface within
which the proposed injection activities will occur.
1 The surficial aquifer exists in unconsolidated material (referred to as Zones A and B) and partially weathered rock
(PWR) (referred to as Zone Q, extending from the water table to the competent bedrock surface. The highly
fractured upper portion of . the bedrock aquifer is referred to as Zone D. For further information, refer to
Attachment 2.

1.2 Pilot Test Area B105-139
Target Treatment Area and Depth
The target treatment area (TTA) for the B105-139 pilot test will measure approximately 70 feet
(ft) by 70 ft (see Figure 9-4b of Attachment 9). The proposed target treatment depth (TTD),
which is within Zone AB of the surficial aquifer, has been selected to extend from 13 to 28 ft
below ground surface (bgs), as shown in Figure 9-6b of Attachment 9. The TTD was chosen to
coincide with the screen interval of well MW-180-H38AB, where the highest concentrations of
TCE in the B105-139 area have been detected.
PTA Layout
The PTA layout will consist of an array of 16 injection wells (IWs), as shown in Figure 9-4b of
Attachment 9. This layout assumes an anticipated effective radius of influence (ROI) of 11 ft
for each IW, so that wells would be spaced on 22 ft centers. The ROI was selected to create a
reasonable distribution of emulsified vegetable oil (EVO) in the subsurface while maintaining
reasonable target injection volumes.. The injection volume to achieve this ROI (injection
volumes are discussed in Attachment 3) has been calculated based upon the TTD described
above, an effective porosity of 0.2, and assumes that the injection fluid will replace about 40% of
the effective pore volume. It is anticipated that the ROI will be achievable in the soil/saprolite of
the Zone AB surficial aquifer.
Two existing AB monitoring wells (MW231-1-138AB and MW180-1-138AB) and one existing CD
monitoring well (MW200-H38CD) are present within the proposed PTA, while one existing AB
monitoring well (MW230-H38AB) is present outside the PTA. These wells will be used for
EISB performance monitoring as described in Attachment 7.' The monitoring network will be
supplemented with two additional AB monitoring wells, one additional CD monitoring well, and
two AB piezometers, as shown in Figure 9-4b of Attachment 9. The locations and number of
proposed IWs as well as the locations of the proposed monitoring wells and piezometers may be
adjusted based on spacing of existing Site features (i.e., trees) in the PTA. The refined layout
and number of wells will not exceed the current design parameters as described above by more
than 50%.
1.3 . Pilot Test Area B147
Target Treatment Area and Depth
The TTA for the B147 PTA will measure approximately 70 ft by 70 ft (see Figure 9-4b of
Attachment 9). The proposed TTD, which is within Zone AB of the surficial aquifer, has been
selected to extend from 15 to 35 ft bgs (see Figure 9-6c of Attachment 9). The TTD was
chosen to extend from the water table (at approximately 15 ft bgs) to the bottom of the MW-147-
1 screen interval (at 35 ft bgs). The proposed TTA and depth for the B147 PTA are based on
currently available perchlorate data but may be refined in the field based on groundwater

samples to be collected for COPC analysis following initial installation of the four corner PTA
injection wells (see Attachment 7).
PTA Layout
The PTA layout consists of an array of 16 IWs (see Figure 9-4b of Attachment 9). The IWs
were spaced approximately 22 ft apart, yielding an effective ROI of 11 ft. The rationale for this
spacing is. the same as described for the well spacing at B105-139 PTA. One existing AB
monitoring well (MW-147-1) is present within the proposed PTA, while one existing AB
monitoring well (MW-147-2) is present outside the PTA. These wells will be used for EISB
performance monitoring as described in Attachment 7. The monitoring network will be
supplemented with two additional AB monitoring wells and two AB piezometers. The locations
of the proposed piezometers were selected based on the regional groundwater flow, as shown in
Figure 9-4b of Attachment .9. The locations and number of proposed IWs, as well as the
locations of the proposed monitoring wells and piezometers, may be adjusted in the field based
on spacing of existing Site features (i.e., trees, berm) in the PTA and after additional data
collection, as described above. The refined layout and number of wells will not exceed the
current design parameters as described above by more than 50%.
1.4 Pilot Test Area B149
Target Treatment Area and Depth
The pilot test will target Zone C near well MW-149-1 (see Figure 9-4c of Attachment 9). The
proposed TTA will measure approximately 60 ft by 60 ft. The pilot test is intended to target the
PWR above the competent bedrock in the B149 area. The thickness of the soil and' saprolite
above the PWR varies in the B149 PTA, and thus the proposed TTD is the 10 ft interval above
the competent bedrock, with a total anticipated depth of between 20 and 50 ft bgs (see Figures 9-
6d/6e of Attachment 9).
PTA Layout
The layout will consist of 4 IWs (see Figure 9-4c of Attachment 9). The layout assumed an
anticipated effective ROI of 19 ft for each IW, so that wells would be spaced on 38 ft centers.
The design ROI for B149 PTA is greater than the design ROI for the B105-139 and B147 PTAs
since the PWR of Zone C and the highly fractured upper portion of the bedrock aquifer (Zone D)
are expected to have greater permeabilities than the Zone AB aquifer material, facilitating greater
injection distribution. The injection volume to achieve this ROI (injection volumes are discussed
in Attachment 3) has been calculated based upon the TTD described above, an effective
porosity of 0.2, and assumes that the injection fluid will replace about 60% of the effective pore
volume. Two existing Zone CD monitoring wells (MW-149-1 and MW183-O39CD) are present
within the proposed PTA. These will be used for EISB performance monitoring as described in
Attachment. 7. To supplement the monitoring network, two additional Zone CD monitoring
wells are proposed (see Figure 9-4c of Attachment 9). One additional Zone C monitoring well

is also proposed to characterize the shallow groundwater above the TTA. The locations and
number of proposed IWs and the locations of the proposed monitoring wells may be adjusted
based on spacing of existing Site features (i.e., trees) in the PTA.

HYDROGEOLOGIC EVALUATION

2. HYDROGEOLOGIC EVALUATION
2.1 Geology and Hydrogeology
The Chemtronics Site lies within the Blue Ridge Physiographic Province (Horton and Zullo,
1991). The Blue Ridge Province is predominately composed of igneous and metamorphic rocks
that have been complexly folded and faulted in a northeasterly direction, parallel to the regional
trend of the mountains. These structural imprints are reflected in the topographic and drainage
patterns within the region. The predominant rock type underlying in the area are high-grade
metamorphic rock of the Ashe Metamorphic Suite.
Y
The geology of the Site is typical of that found in the Blue Ridge Province and consists of soil
and saprolite overlying a partially weathered rock (MR) transition zone which grades into
competent bedrock with depth (Altamont, 2010). A generalized depiction of the primary
components of the hydrogeologic system is presented in Figure 2-1 (Harned and Daniel, 1992).
Unconsolidated material overlying bedrock and extending to the surface is typically known as
overburden. In western North Carolina and other parts of the southern Appalachians, most of the
overburden is derived from in -place weathering of bedrock, although some is from deposition by
streams and rivers (alluvium) or deposition from mass wasting (colluvium). As show in Figure
2-1, the Site is underlain by overburden consisting of soil, saprolite, and weathered rock
overlying bedrock. Soil at the Site typically contains high percentages of clay, silt, and fine
sized particles and thus is anticipated to have relatively low permeability of about 10-2 feet/day
(ft/day), based on literature values for similar materials. The saprolite, which generally ranges
from 2 to 65 ft thick, is highly weathered with variable permeability while the PWR layer
(generally 5 to 10 ft thick) covers the bedrock and is anticipated to have moderate permeability
of about 10-1 ft/day, based on literature values for similar materials. The permeability of the
PWR can be locally variable depending on mineralogy and structure. The predominant bedrock
underlying the Site is muscovite-biotite gneiss while garnet -muscovite schist has also been
encountered (Altamont, 2010). Cross -sections depicting the thickness of the overburden and the
depth to bedrock are shown in Figures 9-6a to Figure 9-6e of Attachment 9.
The majority of the Site is situated within one of two local watersheds which are separated by a
prominent ridge. These watersheds are the Unnamed Branch and Gregg Branch, which are
commonly referred to as the Front Valley and Back Valley, respectively. Both of these
watersheds are part of a larger watershed- (Bee Tree Creek) and a regional watershed (Swannanoa
River; Figure 9-1 of Attachment 9).
Two primary aquifer systems exist at the Site; the surficial aquifer and the bedrock aquifer. The
aquifers are likely interconnected throughout the Site, but each has distinctly different
characteristics that define the groundwater flow paths within them. The surficial aquifer exists in
unconsolidated material (referred to as Zones A and B) and PWR (referred to as Zone C),
extending from the water table to the competent bedrock surface. The highly fractured upper
portion of the bedrock aquifer is referred to as Zone D. The deeper bedrock aquifer (referred to

as Zones E and F) consists of sparsely interconnected joints and fractures within the competent
bedrock.
Potentiometric surface maps for Zone AB and Zone CD, including the locations of the pilot test
areas (PTAs), are shown in Figure 9-4a through Figure 9-4c of Attachment 9. The
potentiometric surface maps for Zone AB and Zone CD indicate that the predominant
groundwater flow direction is generally down -valley towards the southeast. Average
groundwater flow velocities of approximately 0.15 ft/day have been estimated for both the AB
and CD zones of the Front Valley of the Chemtronics Site. This groundwater flow velocity has
been estimated by dividing the specific discharge, calculated using Darcy's Law, by a literature
derived estimate of the effective porosity of the system. These parameters are fairly similar for
Zone AB and Zone CD. The specific discharge was calculated using a hydraulic conductivity
value of 1.17 ft/day, which was estimated from a recent long-term pumping test in the Front
Valley, and a hydraulic gradient of 0.025 ft/ft, which was calculated from groundwater levels
measured in wells in the Front Valley of the Site for Zones AB and CD. A value of 0.21 was
used for the effective porosity and was obtained from a published value for fine sand (Fetter,
1994).
Groundwater elevations were measured within each PTA in April 2012. The recorded depths to
water were: (i) 9.4 ft below ground surface (bgs) at MW180-H38AB in B105-139 PTA; (ii) 12.4
ft bgs at MW-147-1 in B147 PTA; and (iii) 7.75 ft bgs at MW-149-1 in B149 PTA. Review of
historical groundwater level measurements indicates that, in general, the various aquifer zones
respond to seasonal and annual changes in precipitation similarly (Altamont, 2010). Temporal
changes in water -level vary across the Site with a range of a few feet in the Front Valley surficial
aquifer to as much as 6 ft in the bedrock aquifer.

INJECTANT INFORMATION

3. INJECTANT INFORMATION
This attachment provides information on- the proposed injectants for the Enhanced In Situ
Bioremediation (EISB) pilot tests. The proposed injectants include: (i) Newman Zone®, an
emulsified vegetable oil (EVO) which will serve as an electron donor; (ii) KB-10 Plus, which is
a mixture of KB-10and WBC-2 bioaugmentation cultures; (iii) buffer. (sodium bicarbonate,.
calcium carbonate) and/or base (magnesium hydroxide) for pH control; and (iv) EHC®, a slow
release electron donor containing zero-valent iron. Each of the proposed injectants is on the
North Carolina Department of Environment and Natural Resources (NCDENR), Division of
Water Quality (DWQ.), Aquifer Protection Section (APS), Underground Injection Control (UIC)
Program's list of approved injectants2. Material Safety Data Sheets (MSDSs) for each proposed
injectant are provided in Attachment 3-A.
3.1 Pilot Test Design and Implementation Overview
The EISB approach will be to inject a food -grade, slow -release electron donor (EVO that
includes 4% sodium lactate [Newman Zone®]) into the target aquifer zone (either Zone AB or
Zone C, as defined for each pilot test area [PTA] in Attachment 1) to establish a biologically
active zone (BAZ) to promote in situ biodegradation of target compounds of potential concern
(COPCs). For the B105-139 and B149 PTAs, a commercially available bioaugmentation culture
(KB40 Plus) comprised of natural dehalorespiring bacteria, will also be injected to mediate the
full biodegradation of trichloroethene (TCE) to ethene. Bioaugmentation will not be
implemented at the B147 PTA since the microorganisms necessary for. complete biodegradation
of perchlorate, the target COPC in this PTA, are anticipated to be already present in the
subsurface (they are believed to be ubiquitous)..
The target pH range for the B105-139 and B149 PTAs will be between 6.5 and 8.3. The pH in
B105-139 and B149 PTA has been observed to be as low as 4.9 and 5.5, respectively (pH data
provided in Figure 9-5a and Figure 9-5c in Attachment 9). Therefore, a buffer (i.e., sodium
bicarbonate, calcium carbonate) and/or base (i.e., magnesium hydroxide) will also be injected
into the B105-139 and B149 PTA groundwater along with the electron donor to establish and
maintain suitable pH conditions during the pilot tests. In the B 147 PTA, the pH . has been
observed to be as low as 6.1 (pH data provided in Figure 9-5b in Attachment 9). Since bacteria
responsible for reduction of perchlorate, the target COPC in this PTA, remain active at lower pH
levels (compared to the microorganisms responsible for transformation of TCE, the target COPC
in the other PTAs) and the background pH is somewhat higher in this PTA, buffer will not be
added to the B 147 area.

098e5650fl 8e&groupId=38364

Injection of EVO, buffer and, as appropriate, the bioaugmentation culture, into the subsurface
will be performed using a series of injection wells (IWs) distributed across each PTA. The
layouts, target areas, and target depths for each PTA are discussed in Attachment 1.
3.2 Injectant Volumes and Concentrations
This section describes injectant volumes and concentrations. The injectant volumes outlined
below and in Table 3-1 are based on the proposed pilot test layouts, which may be adjusted in
the field based on site conditions and/or additional data collection (see Attachment 1).
Therefore, the injectant volumes may be less than outlined below or, if greater, will not exceed
the outlined quantities by more than 50%.
Electron Donor
The total mass of EVO to be injected in each PTA is a function of. (i) the number of IWs per
PTA (see Table 3-1); (ii) the target treatment volume; and (iii) the target EVO concentration.
The target treatment volume for each injection point was estimated to be approximately 3,450
gallons (gal), 4,600 gal, and 10,600 gal -for the B 105-139, B 147, and B 149 PTAs, respectively.
These estimates assumed design radii of influence (ROIs) and target treatment depths (TTDs) as
specified in Table 3-1 and a porosity of 0.20. A target EVO concentration of 0.5%
(volume/volume [v/v], as oil) was selected for the B147 and B149 PTAs. A target EVO
concentration of 1.0% (v/v, as oil) was selected for B105-139, as this PTA contains higher
COPC concentrations than the other PTAs. Based on performance at other sites, these EVO
concentrations are sufficient to provide electron donor to treat Site COPCs but low enough to
minimize methane production which can occur if the electron donor is over -dosed and if the
resulting oxidation-reduction potential (ORP) is driven too low (i.e. methanogenesis).
Based on the defined ROIs and target concentrations, approximately 260, 175, and 400
kilograms (kg) of EVO will be injected into each 1W in the B105-139, B147, and B149 PTAs,
respectively, with a total of 8,500 kg of EVO planned to be injected during the pilot testing. In
addition, up to 210 kg of a slow release electron donor (EHe) will be added to potable water
that will be used as the injection fluid for bioaugmentation (the EHC® will help make the water
anaerobic, to accommodate the anaerobic microorganisms in the bioaugmentation culture).
Bioaugmentation Culture
KB-10 Plus (which is a mixture of KB-10 and WBC-2 bioaugmentation cultures) is a
commercially available remediation culture provided by SiREM, will be used as the
bioaugmentation culture to promote TCE dechlorination. The total volume of KB-1® Plus
culture recommended by SiREM to provide sufficient microbial mass to stimulate reductive
dechlorination is 32 liters (L) each for the B105-139 and B149 PTAs (see Table 3-1). The
volume of culture will be distributed equally between the IWs in each PTA.

Buffer
Groundwater pH measured in the B105-139 and B149 PTAs is typically below or on the low end
of the range (pH 6.5 to 8.3) for effective biodegradation of chlorinated volatile organic
compounds (cVOCs) (pH data provided in Figure 9-5a and Figure 9-5c in Attachment 9). A
buffer (i.e., sodium bicarbonate, calcium carbonate) and/or base (i.e., magnesium hydroxide) will
be amended to the injection fluid -to provide pH control in the B105-139 and B149 PTAs. A
bench test with soil cuttings generated during well installation will be completed to confirm the
appropriate dose of amendment(s) for pH control for the pilot tests, as the dose will be dependent
on the Site geochemistry. Concentrations are anticipated to be up to 10 g/L for sodium
bicarbonate; 20 g/L for magnesium hydroxide, and 80 g/L for calcium carbonate. It is expected
that lower concentrations may actually be used, pending the results of the bench test. As
discussed above, buffer addition in the 8147 PTA is not planned.
Dilution Water
The injection fluid will be prepared by diluting the EVO to the target concentration with potable
water from the local municipality, with a total volume of up to 55,200, 73,600, and 42,400 gal to
be injected into 13105-139, B147 and B149 PTAs, respectively, during the pilot test.
3.3 Anticipated COPC Transformations
Laboratory and field demonstrations over the past decade have shown that microorganisms in
subsurface environments (e.g., groundwater) can degrade cVOCs, perchlorate and research
department explosive (RDX) to environmentally acceptable end products (DOD, 2004; Hawari et
al., 2000, Crocker and Indest, 2006, Cox et al:, 2000). While these biodegradation reactions can
occur under a range of environmental conditions, the dominant biodegradation mechanism
employed in EISB applications for these COPCs is reduction, which occurs under anaerobic
conditions (absence of oxygen). In each case, the COPCs serve as electron acceptors, and are
reduced, while organic carbon substrates (e.g., EVO) serve as electron donors.
For cVOCs, sue as TCE, the dominant biodegradation mechanism used in EISB applications is
reductive dechlorination, which involves the sequential replacement -of chlorine atoms on the
alkene molecule with hydrogen atoms. Under reducing conditions, TCE is dechlorinated to cis-
1,2-dichloroethene (cis-1,2-DCE) then to vinyl chloride (VC) and finally to ethene. Hydrogen,
typically produced during the bacterial metabolism of simple organic carbon compounds such as
alcohols, organic acids, sugars or edible oils, serves as the electron donor in the dechlorination
reactions. Figure 3-1 shows the common biodegradation pathways for chlorinated ethenes,
including TCE.
Perchlorate biodegradation results from microbially-mediated redox reactions where perchlorate
serves as the electron acceptor and is reduced to chlorate and then to chlorite (Figure 3-2).
Chlorite then undergoes a biologically mediated dismutation reaction, producing chloride and
oxygen.

Anaerobic biodegradation of RDX can proceed through a number of pathways, which include
two -electron reduction, single -electron reduction (or denitration), and direct enzymatic ring
cleavage (Figure 3-3). Biological breakdown products of RDX include carbon dioxide (CO2),
methane, nitrous oxide, hydrazine, and dimethyl hydrazines.
3.4 Anticipated Injectant Transformations
The following subsections describe the injectants' potential for or susceptibility to
transformation in the subsurface.
Electron Donor
Newman Zone® is a biodegradable EVO product that contains both fast- and slow -release
electron donors. In the subsurface, Newman Zone° is anticipated to undergo microbial
biodegradation, producing volatile fatty acids (VFAs) (e.g., lactate, acetate) and dissolved
hydrogen. VFAs and dissolved hydrogen are necessary to stimulate microbial reductive
dechlorination of chlorinated organic compounds; VFAs and dissolved hydrogen get consumed
during the process. Total organic carbon (TOC) analysis, as discussed in Attachment 7, will be
used as an indication of changes in EVO and VFA concentrations. Following injection, it is
expected that the EVO will remain essentially stationary in the subsurface, and will serve as a
long-term source of electron donor to promote biodegradation of the COPCs in these areas.
Similar transformations are anticipated for EHC®; the zero-valent iron in EHC®, which is not
anticipated to be injected itself, is anticipated to react with dissolved oxygen in dilution fluids to
produce anaerobic water.
Bioaugmentation Culture
In the subsurface, the microbial populations within KB-18 Plus are anticipated to grow as they
consume the electron donor/carbon source (Newman Zone°) and transform the chlorinated
organics via reductive dechlorination. Once the chlorinated solvents are degraded, the microbes
no longer have the necessary energy source to continue growing, resulting in the death of the
microbial populations. KB-1® Plus is not expected to undergo chemical or physical
transformation in the subsurface.
Buffer/Base
The addition of a buffer (i.e., sodium bicarbonate, calcium carbonate) or base (i.e., magnesium
hydroxide) are anticipated to neutralize pre-existing acidic groundwater conditions and the
influence of VFA production on groundwater pH.
3.5 Potential Byproduct Formation
In addition to the anticipated transformations of COPCs and injectants discussed in Sections 3.3
and 3.4, respectively, EISB may result in the formation of additional byproducts. For example,

anaerobic conditions established during EISB can enhance the mobility of naturally occurring
iron and manganese. Additionally, EISB can result in the formation of methane. As discussed
above, the proposed EVO concentrations are anticipated to be sufficient to provide electron
donor to treat Site COPCs but low enough to minimize methane production. Dissolved metals
and methane are included in the monitoring program as discussed in Section 7.

Section 5 - Fire Fighting Measures:
Non-flammable
Flash Point: not applicable
Upper flammable limit: not applicable
Lower flammable limit: not applicable
Section 6 — Accidental Release Procedures
Spilled KB-10 Plus should be soaked up with sorbant and saturated with a 10% bleach
solution (prepared by making a one in ten dilution of diluted standard bleach [normally
sold at a strength of 5.25% sodium hypochlorite] to disinfect affected surfaces. Sorbant
should be double bagged and disposed of as indicated in section 12. After removal of
sorbant, area should be washed with 10% bleach solution to disinfect. If liquid from the
culture vessel is present on the fittings, non -designated tubing or exterior of the stainless
steel pressure vessel liquid should be wiped off and the area washed with 10% bleach
solution.
Section 7 - Handling and Storage
KB-10 Plus is shipped in stainless steel pressure vessels in a protective over pack. KB-
1® Plus should be handled with care to avoid any spillage. Vessels are shipped with 1
pound per square inch (psi) pressure; valves should not be opened until connections to
appropriate lines for subsurface injection are in place.
Storage Requirements: Avoid exposing stainless steel pressure vessels to undue
temperature extremes (i.e., temperatures less than 0°C or greater than 300C may result
in harm to the microbial cultures and damage to the vessels). All valves should be in the
closed position when the vessel is not pressurized or not in use to prevent the escape of
gases and to maintain anaerobic conditions in the vessel. Avoid exposure of the culture
to air as the presence of oxygen will kill dechlorinating microorganisms.
Section 8 - Exposure Controls/Personal Protection
Personal protective equipment:
Skin: Protective gloves (latex, vinyl or nitrile) should be worn.
Eye Protection: Wear appropriate protective eyeglasses or goggles when opening
pressure vessels, valves, .or when pressurizing vessels to inject contents into the
subsurface.
Respiratory: No respiratory protection is required.
Engineering Controls: Good general room ventilation is expected to be adequate.

INJECTION PROCEDURE

4. INJECTION PROCEDURE
4.1 Injection Approach
For the B105-139 and B147 pilot test areas (PTAs), the injection approach will consist of a two -
stage process, whereby one set of injection wells will be injected with amendments, while the
remaining set of injection wells (IWs) will be used to monitor the radius of influence (ROI) of
the injections within the PTA.. As target injection volumes are met at the first set of IWs,
injection will transition to the remaining IWs. The' number of IWs simultaneously receiving
amendments will be adjusted to accommodate field -conditions and will balance data needs (i.e.,
assessment of ROI) with observed field conditions (e.g., injection rates and pressures) and
equipment (e.g., number of channels on the injection manifold). For the B149 PTA, where there
are fewer IWs, the proposed injection strategy is to simultaneously inject into all 4 IWs. The
injection quantities into individual IWs in each PTA may be adjusted based on the results from
additional data collection activities during and subsequent to well installation.,
4.2 Injection Procedure and Equipment
During injections, one set of injection equipment (storage tanks, transfer pumps, manifold and
hosing) will be used in each PTA to allow simultaneous injection into multiple IWs. A typical
schematic of the injection equipment to be used is presented in Figure 4-1. At each IW the order
of injection will be: 1) several hundred. gallons (gal) of emulsified vegetable oil (EVO) solution,
2) a small volume of anaerobic water, 3) the bioaugmentation culture KB-10 Plus, 4) a second
volume of anaerobic water, and 5) the remainder of the EVO volume for the injection well. The
anaerobic water is used to protect the KB-10 Plus from oxygen exposure. Anticipated injectant
volumes and concentrations, as detailed in Attachment 3, include approximately 3,450 gal,
4,600 gal, and 10,600 gal of a 1-2% (volume/volume [v/v]) EVO solution (0.5 to 1%v/v as oil)
per injection well for the B105-139, B147, and B149 PTAs, respectively. The total injection
volume for all three PTAs is approximately 171,000 gal. The total volume of KB-10 Plus
proposed is.32 liters (L) each for the B105-139 and B149 PTAs distributed equally between the
IWs in each PTA. Further details regarding the bioaugmentation 'procedures are provided in
Attachment 4-A.
An anticipated average injection rate of 1.5, 1.0 and 1.5 gallons per minute (gpm) per injection
well has been assumed for the EVO injections at the B105-139, B147 and B149.PTAs,
respectively, based on the anticipated geology and target thickness of the treatment zones. At
these injection rates and assuming injection for 6 hours per day to account for daily
setup/takedown of equipment and to switch between injection fluids (EVO solution, KB-10 Plus,
3 Proposed injectant volumes, which were detailed in Attachment 3, are based on the proposed pilot test layouts,
which may be adjusted in the field based on site conditions and/or additional data collection (see Attachment 1).
Therefore, the injectant volumes may be less than outlined in the attachment or, if greater, will not exceed the
outlined quantities by more than 50%.

anaerobic -water), the anticipated average daily injection rate per IW is anticipated to be
approximately 540 gal, 360 gal, and 540 gal for the B 105-139, B147, and B149 PTAs,
respectively. At this average daily injection rate and assuming that injection occurs in
approximately 50%, 50%, and 100% of the 16, 16, and 4_ IWs in B105-139, B147, and B149
PTAs; respectively, the average daily injectant rate per PTA is anticipated to be approximately
4,300, 2,900, and 2,200 gallons per day. At the average daily injection rate for the EVO solution
volumes listed above, it is anticipated that injection event will be approximately 6, 13, and 20
days for the B105-139, B147 and B149 PTAs, respectively. Delays due to weather and
limitations in injection rates are possible. It is expected that at least 4-6 weeks of field work will
be required to inject the full volume for the PTAs at these rates.
The average maximum injection pressure is anticipated to be maintained at or below 20 pounds
per square inch (psi). Higher injection rates, and correspondingly higher daily injection rates and
lower injection durations, may be used if it is found to be practical at this average maximum
pressure.
4.3 Injection Monitoring
One of the objectives of the pilot testing is to evaluate ROI. An estimate of ROI and the
variability of ROI between IWs may be used to refine well spacing for potential technology
scale -up. During EVO injection, ROI monitoring will consist of collecting grab samples from
surrounding locations not receiving injections. These grab samples will be visually inspected
for EVO, which has a milky white color, and field tested for conductivity. and turbidity, which
increase when EVO is present.
During injection, the. injection rate, cumulative volume and injection pressure will be monitored
for each IW. Monitoring will also include measurement of water levels in and around the IWs
and visual observation for short-circuiting/daylighting to ground surface. The operational data
Will be used to support any adjustments in injection rates or pressures, and to confirm that overall
injection targets are met. Should the monitoring data indicate that short-circuiting and/or
daylighting at the ground surface is occurring, the injections will be temporarily stopped and
injection rates/pressures will be decreased and/or injection re -configured.

Injection Procedure for KB-1®/ KBA Plus
List of Equipment
Pressurized cylinder of compressed gas (argon or nitrogen) — locally sourced
I kResek6 Lane; Suite 2
Guelph Ontario N1GSO:
Phone (519) 822=2265
fax: [phone].
The injection field kit provided by SiREM containing equipment and materials required
for injection:
• Stainless steel vessel containing KB-1® or KBA Plus
• Appropriate regulator for compressed inert gas
• Tubing with appropriate fittings for transfer of gas to vessel and inoculum
from vessel to well.
•. Tubing to inject culture into subsurface.
• Digital scale (to measure injection volumes )
Summary of Method
SiREM ships all required equipment and materials to the site prior to the scheduled
injection date. The bioaugmentation technician inspects the vessel integrity upon
arrival at the field site and confirms that all valves are closed and all connections are
secure. The pressure in the vessel and vessel weight are checked to ensure that
they have not changed since leaving the laboratory. The vessel is shipped under slight
positive pressure (1 pound per square'inch [psi]).
The injection technician proceeds with the injection by placing the injection tubing in the
well/drive point to the desired injection depth and purges the well/drive point with argon
or nitrogen gas to displace oxygen from the well column and maintain an inert gas
blanket in the well above the water table. A 5 minute purge is recommended.
The culture is then injected into well/drive point using compressed gas. There are
four stainless steel stems on SiREM vessels: the pressure relief and pressure gauge
'port (to monitor pressure and pressure relief for safety); the purge port (for purging or
venting the vessel); the inoculation port (culture line into subsurface); and the
pressurization port (connected to compressed gas to pressurize vessel and push culture
into the ground) shown in Figure 1. The bioaugmentation technician connects the tubing
so that the compressed gas is used to pressurize the vessel (typical maximum
pressure required is up to 30 psi for injection depths up to 30 feet below ground surface)
and push the culture into the injection tubing and into the well/drive point at the
desired

depth interval. The required volume is metered into the ground and the injection
equipment moved to the next injection as required until all locations are completed.
The bioaugmentation technician facilitates the return of all materials and equipment to
SiREM following completion of the bioaugmentation.
Health and Safety Considerations:
Appropriate protective eyeglasses or goggles are to be worn when opening
vessels valves or pressurizing vessels when injecting contents in to groundwater.
Disposable latex or nitrile gloves should be worn when handling and disposed of after
use.
Spilled liquid should be soaked up with a sorbant and saturated with a 10% bleach
solution (1/10 diluted standard bleach). Sorbant should be double bagged and disposed
of in garbage. After removal of sorbant, area should be washed with 10% bleach
solution to disinfect. If liquid from the culture vessel is present on the fittings, non-
designated.tubing or exterior of the culture vessel liquid should be wiped off and the area
washed with 10% bleach solution.

MONITORING PLAN

7. MONITORING PLAN
This attachment provides information on the proposed monitoring plan. Baseline, injection, and
performance monitoring of groundwater will be performed over time and analyzed to measure
biodegradation of target compounds of potential concern (COPCs), consumption of amendments,
changes in geochemical conditions, and emergence/disappearance of degradation intermediates
and end products (see Attachment 3 for additional details regarding degradation intermediates
and end products).. The results from these tests will be used to evaluate the field implementation
of enhanced in situ bioremediation (EISB).
Lancaster Laboratories, Inc. (LLI) will analyze groundwater samples for target COPCs (i.e.,
volatile organic compounds [VOCs], perchlorate), Research Department Explosive (RDX),
dissolved hydrocarbon gases (DHGs; i.e., methane, ethane and ethene), anions (chloride, sulfate,
sulfide, nitrate, nitrite), total organic carbon (TOC), and dissolved metals (iron, manganese), as
presented in Tables 7-1 and 7-2. In addition, select samples will be submitted to SiREM, for
microbial analysis. The proposed baseline, injection, and performance monitoring schedules are
described in Sections 7.1, 7.2 and 7.3, respectively.
7.1 Baseline Monitoring
Baseline groundwater sampling will be conducted at the monitoring wells and injection wells
(IWs) to characterize the groundwater chemistry prior to implementation of the injection
activities in each pilot test area (PTA). The baseline characterization program is presented in
Table 7-1 and the sample handling and analytical details are presented in Table 7-2.
Baseline groundwater sampling will be completed using low -flow purging and sampling
techniques. Field measurement of pH, dissolved oxygen (DO), oxidation reduction potential
(ORP), specific conductance, turbidity and temperature will be completed during well purging
and groundwater sample collection. Water levels.will be measured to evaluate groundwater flow
directions. The analytical suite for each PTA is described in the following sections.
Pilot Test Area B105-139
Groundwater samples will be collected for baseline VOC analysis from the 16 IWs and the
newly installed Zone AB and Zone CD wells (MW238-H38AB, MW239-H38AB, MW240-
H38CD), to gain a better understanding of the distribution of VOCs in the PTA groundwater.
Groundwater samples will also be collected for VOCs, DHGs, anions, TOC, Perchlorate, RDX
from each of the existing wells (MW1 8 0-H3 8AB,,MW230-H38AB, MW231-H38AB; MW200-
H38CD), and the three newly installed monitoring wells. Samples for microbial molecular
analysis (i.e., vinyl chloride reductase gene) and dissolved metals analysis will be collected from
the one new Zone AB well (MW239-H38AB) and MW180-H38AB. Dissolved metals have
been. included in the analytical suite because the anaerobic conditions established during EISB
can enhance iron and manganese mobility.

Pilot Test Area B147
The four corner IWs will be sampled for baseline analysis of VOCs, perchlorate and RDX.
Based on the results of the additional baseline perchlorate data from the four corner IWs, the
number, depth, and layout of injection and monitoring locations may be refined in B147 PTA, as
discussed in Attachment 3. Additional IWs, which will be installed after refinement of the PTA
layout, will be sampled for perchlorate alone. Groundwater samples will also be collected for
VOCs, anions, TOC, and perchlorate from each of the existing monitoring wells (MW-147-1,
MW-147-2), and from the newly -installed Zone AB wells (MW241-G38AB and MW242-
G38AB). Dissolved metals samples will be collected from well MW-147-1 and one of the newly
installed Zone AB wells.
Pilot Test Area B149
Groundwater samples for baseline VOC analysis will be collected from the 4 IWs as well as the
new Zone C monitoring well (MW245.-039C). Groundwater samples will also be collected for
VOCs, DHGs, anions, TOC, perchlorate and RDX from each of the existing monitoring wells
(MW-149-1, MW183-039CD), and newly -installed transgradient and downgradient Zone CD
monitoring wells (MW243-P39CD and MW244-P39CD). Samples for microbial molecular and
dissolved metals analysis will be collected from wells MW-149-1 and MW183-039CD.
7.2 Injection Monitoring
One of the objectives of the pilot testing is to evaluate radius of influence (ROI). An estimate of
ROI and the variability of ROI between IWs may be used to refine well spacing for potential
technology scale -up. During emulsified vegetable oil (EVO) injection, ROI monitoring will
consist of collecting grab samples from surrounding locations not receiving injections (i.e.,
inactive IWs, monitoring wells, and/or piezometers). These grab samples will be visually
inspected for EVO, which has a milky white color, and field tested for conductivity and turbidity,
which increase when EVO is present.
During injection, the injection rate, cumulative volume and injection pressure will be monitored
for each IW. Monitoring will also include measurement of water levels in and around the IWs
and visual observation for short-circuiting/daylighting to ground surface. The operational data
will be used to support any adjustments in injection rates or pressures, and to confirm that overall
injection targets are met. Should the monitoring data indicate that short-circuiting and/or
daylighting at the ground surface is occurring, the injections will be temporarily stopped and
injection rates/pressures will be decreased and/or injection re -configured.

7.3 Performance Monitoring
The purpose of the performance monitoring program is to track and document the progress of
EISB in each PTA. The groundwater monitoring program for the pilot test will include four
quarterly monitoring events following the injections, with a pilot test duration of 1 year. The
performance monitoring schedule is presented in Table 7-1. The sample handling and analytical
details are presented in Table 7-2. The following subsections present the approach; methods and
schedule to complete performance monitoring for the pilot tests.
The approach and methods to collect and analyze groundwater samples for the performance
monitoring program will be similar to that described for the baseline sample event (Section 7.1).
Field measurement of pH, DO, ORP, specific conductance, turbidity and temperature will be
completed during well purging and groundwater sample collection. Water levels will be
measured during each monitoring event to evaluate flow directions. The analytical suite and
schedule for analysis for each PTA is described in the following subsections.
Pilot Test Area BI05-139
Groundwater samples will be collected on a quarterly basis for the one year pilot test duration for
analysis of VOCs, DHGs, anions, and TOC from each of the existing monitoring wells (MW180-
H38AB, MW230-H38AB, MW231-H38AB, MW200-H38CD), and the newly -installed Zone
AB and CD monitoring wells (MW238-H38AB, MW239-H38AB, MW240-H38CD). Samples
for microbial molecular analysis will be collected on a quarterly basis from well MW180-
H38AB only. Samples for analysis of dissolved metals will be collected during the fourth
quarter monitoring event, from well MW180-H38AB and one new Zone AB monitoring well
(MW239-H38AB).
Pilot Test Area B147
Groundwater samples will be collected on a quarterly basis for the one year pilot test duration for
analysis of perchlorate, anions and TOC from each of the existing monitoring"wells (MW-147-1,
MW-147-2), and the newly -installed Zone AB monitoring wells (MW241-G38AB and MW242-
G38AB). Samples for analysis of dissolved metals will be collected from well MW-147-1 and
one of the new Zone AB wells during the fourth quarter monitoring event.
Pilot Test Area B149
Groundwater samples will be collected on a quarterly basis for the one year pilot test duration for
analysis of VOCs, DHGs, anions, and TOC from each of the existing monitoring wells (MW-
149-1, MW183-O39CD), and the two newly -installed Zone CD monitoring wells (MW243-
P39CD and MW244-P39CD). A sample for microbial molecular analysis will be collected from
well MW-183-O39CD during each of the quarterly monitoring events. Samples for analysis of

dissolved metals will be collected from MW-149-1 and MW183-039CD during the fourth
quarter monitoring event.
