1.0 Introduction
RECEIVEDIDENRINQ
MAY 16 2012
Aquifer Protection Section
On behalf of the North Carolina Department of Transportation (DOT), Hart & Hickman, PC
(H&H) has prepared this report to present post -injection performance monitoring data for the
former North Carolina Department of Transportation (DOT) Asphalt Testing Site No. 17-4
(DENR Ground Water Incident No. 10831). The site is located north of NC Highway 73 West
and west of US Highway 29 in Concord, Cabarrus County, North Carolina (Figure 1). A site
map is provided as Figure 2.
Soil and ground water impacts from former asphalt testing operations by NC DOT were
previously identified at the site. The asphalt testing utilized trichloroethene (TCE), 1,1,1-
trichloroethane (1,1,1-TCA), and/or carbon tetrachloride (CTC). The approved CAP included
excavation for source area soil and monitored natural attenuation (MNA) for ground water
impacts. Approximately 141 tons of impacted soil was removed from the source area in October
2002 as reported in H&H's CAP Addendum report. Confirmation soil samples indicated that
soils were adequately removed. Monitored natural attenuation, consisting of semi-annual ground
water monitoring, was conducted at the site from 2002 to 2009 for ground water impacts. Since
2009, annual ground water monitoring has been conducted at the site.
Because TCE concentrations remain more than 2 orders of magnitude above the ground water
standard and because the plume appears to be migrating toward the stream, H&H recommended
that a bioenhancement event be conducted in source area shallow ground water in the areas
where groundwater TCE concentrations were the highest. The bioenhancement event would
improve the subsurface conditions for more efficient natural attenuation by reductive
dechlorination.

SMARTER ENVIRONMENTAL SOLUf10NS

On behalf of DOT, H&H prepared an Underground Injection Control (UIC) Permit Application
dated May 27, 2011 to conduct a bioenhancement injection at the site. The injectant selected for
the bioenhancement injection event was an emulsified oil substrate (EOS'�. DENR issued the
UIC permit on July 20, 2011.
This post -injection semi-annual ground water monitoring report includes a summary description
and acquired data from the following activities:
• water supply well survey update;
• pre -injection groundwater monitoring event in August 2011
• bioenhancement injection activities in August and September 2011:
• first quarterly post -injection monitoring event in October 2011;
• second quarterly post -injection monitoring event in January 2012; and,
• evaluation of natural attenuation parameters.

2.0 Potential Receptor Survey Update
The original receptor survey was conducted by H&H in November 2000. The most recent
receptor survey update was conducted on October 22, 2011 and is discussed below.
2.1 Water Supply Wells
To identify potential receptors in the vicinity of the site, H&H initially performed a receptor
survey within a 2,000-ft radius of the former testing laboratory in November 2000. The receptor
survey is updated annually. Previous receptor surveys have identified ten private water supply
wells within the 2000-ft search radius. No water supply wells are located downgradient of the
source area. The closest water supply well is 900 ft from the source area and is only used for
irrigation. Table 1 summarizes the water supply well information. Apart from well ownership
information, H&H determined that there were no changes to the previously obtained information
during the October 2011 receptor, survey update. Figure 3 depicts the locations of the ten
identified water supply wells. Municipal water is available and is otherwise in use near the site.
Nearby off -site water supply wells were previously sampled, and out -of -service on -site water
wells were last sampled in April 2004 (Table 2). NC DOT target compounds were not detected
in off -site water supply wells in the previous sampling events. Additionally, target compounds
were not detected above standards in the out -of -service on -site water supply wells during the
April 2004 sampling event. Two 'on -site water supply wells, WS-1 and WS-3, were abandoned
on October 6, 2004. The remaining on -site water supply well, WS-2, was disconnected on
October 6, 2004, but was left in place for use as a monitoring well (MW-WS-2).
2.2 'Surface Water
A small unnamed stream is located approximately 1,000 ft west of the former asphalt testing
laboratory. The unnamed stream is a tributary of Irish Buffalo Creek, which is a Class C surface
water. Based on the potentiometric map, the overall ground water flow is to the west and toward

this stream. Due to the ground water flow direction, the stream is a potential ground water
receptor (Section 4.3).

3.0 EOS® Injection
As recommended by H&H and with the DENR approved UIC permit dated July 20, 2011, H&H
implemented in -situ enhanced bioremediation to address groundwater contamination at the site.
The enhanced bioremediation approach consisted of the subsurface injection of Emulsified Oil
Substrate® (EOS®) in the source area to stimulate reductive dechlorination of chlorinated
solvents in groundwater. Implementation of the injection event included installing fifty eight
temporary direct push technology (DPT) injection points and twelve P PVC temporary injection
wells and injecting the EOS into the upper saturated zone.
3.1 Injection Rationale
Biodegradation of chlorinated ethenes and ethanes, such as TCE and 1,1,1-TCA, typically occurs
by a process known as reductive dechlorination. In this process, organic carbon (which serves as
a source of hydrogen) serves as an electron donor and the chlorinated ethene or ethane serves as
the electron acceptor. Because oxygen is a more favored electron acceptor than chlorinated
ethenes/ethanes, reductive dechlorination occurs most favorably under anaerobic conditions.
Groundwater data for the site suggested that reductive dechlorination processes at the site may be
electron donor limited due to an insufficient supply of organic carbon. To overcome this
limitation, the supply of organic carbon was augmented to enhance chlorinated ethene/ethane
biodegradation.
There are many organic substrates which can be naturally fermented in the subsurface resulting in
the generation of hydrogen to stimulate reductive dechlorination. These materials include lactate,
sugar, molasses, HRC®, and vegetable oil. These materials are all effective but vary in their cost
and longevity. H&H selected EOS® for this site because it is:
0 Effective for the constituents of concern at the site;
• Easy to inject and distribute 'in the subsurface resulting in the need for fewer injection
points;

SMARTER ENVIRONMENTAL SOLUUONS

• A long-lasting, time -release substrate that will likely only require one injection for
significant mass reduction; and
• Safe to handle consisting of only food -grade materials.
The specific EOS® product that was injected is EOS® 598B42. A Material Safety Data Sheet
(MSDS) for this product is attached in Appendix B, and the composition is summarized below.

EOS® 598B42 also includes a vitamin B12 supplement. Several studies have shown that growth
of dechlorinating microorganisms may be enhanced by providing these bacteria with amino acids
and/or vitamins, specifically vitamin B12. All materials contained in EOS® are Generally
Recognized As Safe (GRAS) food -grade materials.
The EOS® amendment is easy to handle, has a low viscosity similar to milk, does not clog
aquifers, and lasts well in excess of three years. EOS® has been applied at over 100 sites,
including multiple sites in North Carolina. EOS® was delivered to the site as a concentrate that
was diluted in the field with potable water prior to injection. The emulsion was injected and
distributed throughout the target source area treatment zone using temporary DPT and P PVC
injection wells. The injected EOS® will be trapped within the soil pores leaving a residual oil
phase to support long-term anaerobic biodegradation of the target contaminants.

3.2 Injection Well Installation
Implementation of the remedy required the advancement of temporary injection wells employing
DPT methods. DPT refusal occurred in 12 boring locations above the planned injection interval
due to the presence of weathered rock. For boring locations where shallow DPT refusal was
encountered, 1" temporary PVC wells were installed using air hammer drilling methods. On
August 29, 2011 through September 22, 2011, 58 temporary DPT injection wells and 12
temporary 1" PVC wells were installed approximately 25 ft apart within the target treatment area.
There were a total of 70 injection points. The injection area and injection well locations are
depicted on Figure 4.
The DPT temporary injection wells were advanced to depths ranging from approximately 34 ft to
45 ft below ground surface (bgs). A four-ft long, 1.75-inch-diameter stainless steel sheath with a
detachable drive point was driven to the target well depth. A typical temporary injection well
r
diagram is shown in Figure 5. In each well, injection was performed over a borehole interval
ranging from 6 to 15 feet (and approximately 34 ft to 45 ft bgs). The rods and sheath were
retracted up the borehole at approximately intervals of 2 ft to 4 ft to allow injection of a
predetermined volume of EOS® substrate over each interval until the total injection interval was
completed. No drill cuttings were generated by this approach. After completion of injection
activities, each borehole was abandoned with a bentonite-grout slurry.
The 1-inch diameter PVC temporary injection wells were advanced to depths ranging from
approximately 40 ft to 43 ft bgs. Each temporary well was constructed of 1-inch diameter PVC
casing with 10 ft of 0.010-slot PVC well screen. A typical temporary injection well diagram is
shown in Figure 6. Drill cuttings were spread in the vicinity of the temporary injection well.
After completion of injection activities, each 1-inch diameter PVC injection well was abandoned
with a bentonite-grout slurry. Well construction and abandonment records for the 1-inch
diameter PVC injection wells are included in Appendix A.

3.3 Description of EOS® Injection
The objective of the EOS® injection was to reduce chlorinated solvents in source area
groundwater by specifically targeting an approximately 15-ft thick vertical zone within saturated
soils. The injection sequence consisted of blending the EOS® concentrate with potable water and
injecting the diluted EOS® into the injection wells. Seventy 55-gallon drums of EOS®
concentrate were delivered to the site prior to the field activities.
The EOS° concentrate was diluted with potable water obtained from the City of Concord Water
Department. The water was hauled by the contractor to the site. Because the water was obtained
from a public water supply, it did not require additional on -site treatment for use in the injection
process. The EOS® concentrate was mixed with water prior to injection using an approximate
mixing ratio of 1:4 (EOS® to water). For the project, a total of approximately 3,654 gallons of
EOS® concentrate were mixed with approximately 14,546 gallons of potable water and injected
into the subsurface. The quantity of EOS® was determined using EOS Remediation, LLC's
EOS® Design Tool (Version 3.0) software. Approximately 260 gallons of diluted EOS® mixture
were injected into each injection well.
The EOS injection activities were conducted on August 29 through September 22, 2011.
Injection equipment schematics are shown in Figures 5 and 6. EOS® was batch -mixed in a 500-
gallon poly tank and then pumped into the injection wells. A pressure gauge, flow meter, and a
valve were used to regulate the injection pressure and flow rate for each injection well. During
the injection process, flow rates and volumes were measured with a totalizing flow meter.
Pressures were measured with pressure gauges and ranged from 20 psi to 60 psi throughout the
injection event.

4.0 Ground Water/Surface Water Monitoring
As outlined in the UIC permit, H&H conducted a pre -injection groundwater monitoring event on
August 18 and 19, 2011 to establish a baseline for comparison with post -injection monitoring data.
Additionally, H&H performed quarterly post -injection monitoring events in October 2011 and
January 2012 to assess the performance of the implemented enhanced bioremediation remedy. The
first quarterly sampling event was a comprehensive event as outlined in the UIC permit application.
The groundwater sampling procedures and monitoring results are discussed below. The locations
of the monitoring and temporary injection wells are indicated on Figure 4, and monitoring well
construction information is provided in Table 3.
4.1 Data Collection Procedures
The scope of each sampling event is summarized below:
Baseline, pre -injection sampling event (August 15 and 16, 2011)
• H&H sampled ten monitoring wells including shallow wells MW-6, MW-9, MW-12, MW-
13, MW-14, MW-15, GP-15, GP-16, and GP-17, and deeper well MW-91 for laboratory
analysis of VOCs by Environmental Protection Agency (EPA) Method 6200B (reporting
the EPA Method 601 list), nitrate, sulfate, metabolic acids, methane, ethane, ethene, and
total organic carbon (TOC). Field measurements were also collected from these wells for
dissolved oxygen (DO), oxidation-reduction potential (ORP), ferrous iron, pH, and
temperature.
First quarterly post -injection comprehensive sampling event (October 22 and 23, 2011)
• H&H sampled fourteen monitoring wells including shallow wells MW-6, MW-9, MW-12,
MW-13, MW-14, MW-15, GP-15, GP-16, and GP-17, and deeper wells MW-6A, MW-9I,
MW-9A, MW-10A, and MW-WS-2. Monitoring wells MW-6, MW-9, MW-12, MW-13,

MW-14, MW-15, GP-15, GP-16, GP-17, and MW-9I were sampled for laboratory analysis
of VOCs by EPA Method SW846-8260B, nitrate, sulfate, metabolic acids, methane,
ethane, ethene, and TOC, and monitoring wells MW-6A, MW-9A, MW-10A, and MW-
WS-2 were sampled for VOCs by EPA Method SW846-8260B only. Field measurements
for DO, ORP, ferrous iron, pH, and temperature also were collected from the monitoring
wells. In addition, one surface water sample was collected from the small unnamed
stream located on the western portion of the site for laboratory analysis of VOCs by EPA
Method 8260.
i
�,Seeorrd±quarter-l-y post: injectionrsamping_event=(7arr� ua y �S�and_26;�2. 1.2)
H&H sampled ten monitoring wells including shallow wells MW-6, MW-9, MW-12, MW-
13, MW-14, MW-15, GP-15, GP-16, and GP-17, and deeper well MW-91 for laboratory
analysis of VOCs by EPA Method SW846-8260B, nitrate, sulfate, metabolic acids,
methane, ethane, ethene, and TOC. Field measurements were also collected from these
1
wells for DO, ORP, ferrous iron, pH, and temperature.
Each sampling event was conducted using the following procedures. After well water levels
were gauged, DO concentrations were measured using a downhole probe. Following DO
measurements and prior to collection of ground water samples, the target wells were purged
using either dedicated disposable bailers or a submersible pump until pH, temperature, and
specific conductivity values stabilized. If a well went dry during purging, the purging process
was considered to be complete. Ground water samples were collected with dedicated disposable
- bailers.
Ground water samples were collected and subsequently submitted for laboratory analyses of
VOCS using methods listed above. Laboratory analyses were conducted by Pace Analytical
Laboratories, Inc., a North Carolina -certified laboratory. Dedicated laboratory -supplied sample
bottles were used for sample collection. A chain -of -custody record was completed for samples
collected and included sample description, date collected, time collected, matrix, sample

container information, and analyses required. The chain -of -custody was signed by H&H and
placed along with the samples in a chilled cooler for hand delivery to the laboratory by H&H.
Copies of the laboratory analytical data sheets and chain -of -custody records are provided in
Appendix C.
Due to the historical presence of TCE in monitoring wells MW-6, MW-9, and MW-14 above the
RCRA standard, the purge water from these wells was contained in drums. A composite sample
was collected from the drummed water for laboratory analysis for disposal characterization
purposes. Based on drum sample results in October 2011 and April 2012, the purge water is not
hazardous waste.
4.2 Ground Water Levels and Flow Direction
Water levels in site monitoring wells were gauged using an electronic water level meter on
August 15, 2011, October 22, 2011, and January 25, 2012 (Table 3). The estimated shallow
potentiometric map constructed from the January 2012 ground water elevation data is presented
in Figure 7. Consistent with previous data, the ground water flow direction in the shallow
aquifer is generally to the west toward the unnamed intermittent stream located approximately
1,000 ft west of the former laboratory building. A deeper ground water potentiometric map
constructed from the January 2012 ground water elevation data is presented in Figure 8. The
deeper ground water flow direction also is generally to the west.
4.3 Surface Water Flow and Sampling
During the October 2011 quarterly post -injection comprehensive monitoring event, H&H
attempted to collect stream flow data and collected a surface water sample from the unnamed
stream located downgradient (west) of the former laboratory site (Figure 2). Stream flow data
could not be collected because the base flow in the stream was too low due to recent drought
conditions. A surface water sample was collected by lowering a bailer into the stream bed. The
stream sample was analyzed for purgeable halocarbons by EPA Method 8260.

SMARTER ENNHONMENTAL SOLUTIONS

No VOCs were detected in the October 2011 surface water sample (Table 4).
4.4 Ground Water Analytical Data
Baseline Sampling; Event (August 2011)
NC DOT target compounds and their potential degradation products were detected above 2L
ground water quality standards in nine monitoring wells (MW-6, MW-9, MW-12, MW-13, MW-
14, MW-15, GP-15, GP-16 and GP-17) in August 2011. No VOCs were detected above 2L
standards in deeper ground water. Consistent with recent well sampling results, the most
elevated COC concentrations were detected in MW-9. Analytical results for shallow ground
water are shown in Table 5, and deeper ground water results are shown in Table 6.
Please note that methylene chloride was detected at a concentration of 3.8 µg/1 in the trip blank
sample and 5.8 µg/l in MW-13 in August 2011. Methylene chloride is not a typical site
contaminant and was not detected in MW-13 in October 2011 and January 2012. As a result, the
detected methylene chloride concentrations were likely laboratory introduced.
First Quarterly Post -Injection Comprehensive Sampling Event (October 2011)
Following the EOS injection in August and September 2011, quarterly post -injection monitoring
was initiated. The first quarterly post -injection monitoring sampling event was conducted on
October 22 and 23, 2011 and approximately one month after the injection event. The NC DOT
target compounds and their potential degradation products were detected above 2L ground water
quality standards in nine monitoring wells (MW-6, MW-9, MW-12, MW-13, MW-14, MW-15,
GP-15, GP-16 and GP-17). No VOCs were detected above 21, standards in deeper ground water.
As with the August 2011 sampling results, the most elevated COC concentrations were detected
in plume well MW-9. Analytical results for shallow ground water are shown in Table 5, and
deeper ground water results are shown in Table 6. Analytical results for former WS-2, now
designated as MW-WS-2, are provided in Table 2.

SAAAA-Master ProjectsM DOT-DOTIDOT402 Concord 17-4WOV 11 GW\GW Rep.doc hart hickman
SMAKrEit ENVIRONMENTAL SOLUTIONS

Post -injection October 2011 data indicated that TCE levels decreased from 695 µg/l to 361 µg/l
in plume well MW-9, 204 µg/1 to 89.8 µg/l in plume well MW-13, and 185 µg/1 to 5.5 µg/1 in
downgradient well GP-15. In addition, 1,1,1-TCA levels decreased from 64.7 µg/l to 34.8 µg/l
and 22.6 µg/l to 6.3 µg/l in plume wells MW-9 and MW-13, respectively. These trends indicate
that the EOS® injection has resulted in enhanced bioremediation within portions of the ground
water plume area.
Please note that TCE concentration in MW-15 increased from 7.6 µg/1 in August 2011 to 172
µg/l after the injection in October 2011. In January 2012, the TCE concentration in MW-15
returned to a concentration (5.3 µg/1) similar to historical pre -injection concentrations. H&H will
monitor TCE concentrations in MW-15 during future monitoring events.
Second Quarterly Post -Injection Sampling Event (January 2012)
NC DOT target compounds and their potential degradation products were detected above 2L
ground water quality standards in nine monitoring wells (MW-6, MW-9, MW-12, MW-13, MW-
14, MW-15, GP-15, GP-16 and GP-17) in January 2012. The most elevated COC concentrations
were detected in plume well MW-14. In addition, vinyl chloride (VC) was detected above its
ground water standard of 0.03 µg/l in MW-13. Analytical results for shallow ground water are
shown in Table 5, and deeper ground water results are shown in Table 6.
January 2012 data generally indicated that TCE and TCA levels 'continued to decrease in the
plume wells. The biggest reductions were noted in MW-9 and MW-13. TCE levels decreased
from 361 µg/1 to 203 µg/1 in MW-9 and 89.8 µg/1 to 3 µg/l in MW-13. Additionally, the TCA
level in MW-9 decreased from 34.8 µg/1 to 15.5 µg/l. These trends again indicate that the EOS®
injection has resulted in bioremediation within portions of the ground water plume area.
Concentration trends will continue to be evaluated during future quarterly sampling events.
TCE, 1,1,1-TCA and 1,1-DCE concentrations in shallow and deeper ground water are depicted

5.0 Evaluation of Natural Attenuation Parameters
Natural attenuation of ground water contaminants occurs by physical, chemical, and biological'
processes. Biodegradation by reductive dechlorination is a primary degradation pathway for the
type of constituents present at the site. Additional data on reductive dechlorination including
indicator parameter data and daughter product concentrations are discussed below.
The target DOT compounds at the site are amenable to natural attenuation. 1,1,1-TCA and TCE
predominantly biodegrade under anaerobic conditions by a process known as reductive
dechlorination. 1,1,1-TCA also degrades abiotically to 1,1-DCE. Historically, there has been
some evidence of natural degradation of these compounds based on the presence of potential
daughter products: 1,1-DCE, 1,1-DCA, and cis-1,2-DCE. However, natural site conditions were
not highly favorable for reductive dechlorination.
The EOS® injection was designed to enhance conditions for biodegradation of the constituents of
concern, and favorable results are being observed since the injection of EOS® in August and
September 2011. Recent and historical biodegradation data are presented in Tables 7 and 8. A
discussion of the recent indicator parameter data from January 2012 is provided below.
5.1 Competing Electron Acceptors
Various electron acceptors can potentially compete with reductive dechlorination, including DO,
nitrate, sulfate, iron (III), and carbon dioxide (methanogenesis). Each sequential reaction reduces
the ORP of the groundwater into the range within which anaerobic reductive dechlorination can
occur most efficiently. These parameters or their byproducts (e.g., Fe(II) and methane) were
measured to assess the prevailing redox conditions at the site. A brief discussion of each
parameter (January 2012) is provided below.

Dissolved Oxygen
DO is used by microbes as an electron acceptor for the biodegradation of organic carbon.
Reductive dechlorination occurs under anaerobic or low DO conditions. DO concentrations of
less than 5 mg/1 may be acceptable, while concentrations less than 0.5 mg/l are ideal.
Dissolved oxygen measurements ranged from 1.11 mg/l (MW-13) to 5.68 mg/l (MW-14) in
January 2012. Apart from MW-9I, MW-6, and MW-14, monitoring well dissolved oxygen
readings were less than 5 mg/l during the January 2012 sampling event. Monitoring wells with
dissolved oxygen levels close to or less than 1.0 mg/1 included monitoring wells MW-9, MW-13,
MW-15, GP-15, and GP-16. The measured dissolved oxygen concentrations in most impacted
monitoring wells indicate conditions marginally conducive for reductive dechlorination to occur.
Nitrate/Nitrite
Nitrate may be used as an electron acceptor for anaerobic biodegradation via denitrification. In
this process, nitrate is reduced and nitrite is produced. In general, nitrate concentrations in the
plume less than background are considered indicative of anaerobic biodegradation. At
concentrations greater than 1 mg/l, nitrate may compete with the reductive dechlorination
process.
Nitrate was detected at concentrations which ranged from <0.2 mg/l (MW-9, MW-13, and GP-
17) to 2.4 mg/1 (MW-9I) in January 2012. These data suggest that nitrate reduction may be
occurring in the plume, indicating the presence of anaerobic conditions favorable for reductive
dechlorination. Most nitrate levels were less than 1 mg/l, and the potential for significant
competition with reductive dechlorination is low.
Sulfate
Sulfate also may be used as an electron acceptor for anaerobic biodegradation. This process is
known as sulfate reduction and results in the depletion of sulfate and production of sulfide in the
aquifer. Sulfate concentrations within the plume below background concentrations are indicative
16 14
SAAAA-Master Projects\NC DOT-DOT\DOT402 Concord 174\NOV 11 GW\GW Rep.doc hart hickman
SMARTER ENOROMNENTAL sownoNs

of anaerobic degradation by sulfate reduction. In addition, sulfate at concentrations greater than
20 mg/l may compete with reductive dechlorination processes.
Sulfate was detected at concentrations which ranged from <5.0 mg/1(MW-9 and MW-13) to 94.8
mg/1(MW-15) in January 2012. Sulfate concentrations in the plume wells were generally greater
than the concentration (<20 mg/1) considered most favorable for reductive dechlorination. In
general, sulfate concentrations do not appear to indicate the potential for significant competition
with reductive dechlorination.
Iron II
Iron reduction is an anaerobic process in which Fe3+ is reduced to Fee+. The reduced form of iron
is soluble. The presence of ferrous iron in ground water greater than 1.0 mg/1 is typically
considered to be. an indication of iron -reducing conditions. In January 2012, ferrous iron was
generally not detected (<0.2 mg/1), other than 6.5 mg/l in MW-9 and 3 mg/1 in MW-13.
Therefore, iron reduction does not appear to be a widespread anaerobic process.
Methane
The presence of methane above background conditions indicates microbial degradation
(methanogenesis) is occurring and strongly reducing conditions have been established. The
fastest rates of anaerobic dechlorination typically occur under methanogenic conditions.
In January 2012, methane was generally not detected (<10 µg/1), other than 426 µg/l in MW-9
and 1,170 mg/1 in MW-13. These results indicate that strongly reducing conditions are present in
portions of the plume.
5.2 Geochemical Indicator Parameters
Parameters that are indicators of conditions favorable for anaerobic biodegradation of chlorinated
solvents include ORP, pH, and temperature. Ethene/ethane (end products) can also serve as
indicators of biodegradation. A summary of these data and recent previous natural attenuation
17
SAAAA-Master Projects\NC DOT-DOT\DOT402 Concord 17-4\NOV 11 GW\GW Rep.doc hart : hickman
' SNAKIER ENMRONMENTAL SOLUTIONS

indicator and target COC data are provided in Tables 7 and 8. These parameters were evaluated
to assess biodegradation processes at the site, and the results are discussed below.
Redox Conditions (ORP)
The ORP of groundwater is a measure of electron activity and is an indicator of the relative
tendency of a solution to accept or transfer electrons. ORP of a groundwater system affects
biodegradation rates. Reductive dechlorination is most efficient in the ORP range corresponding
to sulfate reduction and methanogenesis (<-100 mV), but reductive dechlorination also occurs in
the ORP range associated with nitrate, manganese, and iron reduction (-50 mV to 740 mV).
ORP ranged from -86 mV (MW-9) to 259 mV (MW-12) in January 2012. ORP data are
generally lower in impacted wells and are within the range in which reductive dechlorination
may occur.
pH and Temperature
Groundwater pH values ranging from 5 to 8 standard units are generally preferable for anaerobic
biodegradation. The pH of groundwater affects the presence and activity. of microbial
populations. Acid generated during reductive dechlorination can decrease pH levels after a
bioenhancement injection. Post -injection, groundwater pH ranged from 5.58 to 6.97 in January
2012. The site pH values are close to or within the range which is considered to be favorable for
reductive dechlorination.
Temperature does not greatly influence reductive dechlorination, but temperatures greater than
20 C may accelerate biochemical processes. In January 2012, temperatures ranged from 13.3 C
to 18.1 C. The average shallow groundwater temperature for the site is approximately 15.5 'C.
These temperatures are in the range which is considered satisfactory for biodegradation.
Ethene and Ethane
The dissolved gases ethene and ethane are non -toxic end products of reductive dechlorination of
chlorinated solvents. Dissolved ethene and ethane were not detected in any of the site wells in
SAAAA-MasterProjectANC DOT-DOT\DOT402 Concord 174INOV it GWtGW Rep.doc 18 hart : hickman
SMARTER ENVIRONMENTAL SOWTIONS

the pre -injection or post -injection monitoring events. Because ethene and ethane are highly
volatile, it is not usual that these compounds were not detected in groundwater samples even if
they may have been present.
5.3 Electron Donor
TOC
TOC is utilized as an electron donor in the reductive dechlorination process and, therefore, is
needed to drive the process. Organic carbon can be either naturally occurring or introduced
artificially. The goal of the EOS injection was to provide a carbon source to drive the reductive
dechlorination process.
The presence of TOC at concentrations greater than 20 mg/L is considered ideal for
biodegradation of chlorinated solvents. In January 2012, TOC levels ranged from 1.4 mg/l
(MW-12) to 118 mg/1 (MW-13). TOC concentrations in MW-9 and MW-13 increased from 3.2
mg/l and 1.2 mg/l in August 2011 to 91.8 mg/l and 118 mg/l after bioenhancement injection in
January 2012, respectively. These results indicate that the bioenhancement injection has
successfully increased available TOC in portions of the plume for facilitating reductive
dechlorination processes. H&H will continue to will monitor for the presence of TOC in other
portions of the plume during future monitoring events.
Metabolic Acids
In groundwater, fermentation of EOS produces metabolic acids including lactic, pyruvic, acetic,
propionic, and butyric acids. The production of these acids releases hydrogen into groundwater
which is then utilized by indigenous microbes in reductive dechlorination. In October 2011 and
January 2012, groundwater samples from wells within and downgradient of the source area
injection were analyzed for metabolic acids to evaluate the presence of EOS breakdown products.
The metabolic acid results are summarized in Tables 7 and 8. Metabolic acids were detected in
plume wells MW-9, MW-13, and MW-15 which indicate that EOS® is performing as expected in
1

SMARTER ENVIRONMENTAL SOLUTIONS

portions of the plume. H&H will continue to monitor for the presence of metabolic acids in other .
portions of the plume during future monitoring events.
5.4 Presence of Degradation Daughter Products
Degradation daughter products have been detected in site groundwater. The presence of the
1,1,1-TCA daughter product 1,1-DCA and TCE daughter product cis-1,2-dicholorethene (cis-1,2-
DCE) provide direct evidence that biodegradation by reductive dechlorination of primary COCs
has occurred. However, TCE concentrations remain considerably higher than daughter product
concentrations in the majority of site monitoring wells.
As previously stated, VC was detected above its ground water standard of in MW-13. The
detection of VC in MW-13 may indicate the incomplete reduction of TCE to ethene possibly due
to the lack of a strong reducing environment near this well. H&H will monitor VC
concentrations in MW-13 during future monitoring events.
In addition to reductive dechlorination, 1,1,1-TCA also undergoes significant degradation by
abiotic processes in which it is transformed to 1,1-DCE or acetate in the presence of water. The
�Ipresence of significant 1,1-DCE concentrations compared to TCA in wells MW-9, MW-13, and
MW-14 indicates that abiotic degradation of TCA is also occurring in the plume area.

6.0 Summary and Conclusions
H&H has implemented an enhanced bioremediation remedy and completed the pre -injection
baseline and first and second quarterly post -injection performance monitoring events at the former
DOT Asphalt Testing Site No. 17-4 in Concord, NC. The purpose of the remedial action was to
address chlorinated solvents in source area groundwater. The pre -injection baseline monitoring
event was completed in August 2011 and the first and second quarterly post -injection performance
monitoring events were completed in October 2011 (1-month post -injection) and January 2012,
respectively. The following summarizes the results of the sampling events and performance of
the bioenhancement injection activities:
• Groundwater impacts, including TCE, 1,1,1-TCA, and their daughter products, are
present near and downgradient of the former asphalt testing laboratory. Groundwater
impacts exceed groundwater standards in nine shallow monitoring wells. No impacts
above standards were detected in deeper monitoring wells.
• . A small, unnamed intermittent stream is located approximately 1,000 ft west of the
former laboratory building. No target compounds were detected in a stream sample
collected in October 2011. TCE has previously been detected in the stream on multiple
occasions.
• Consistent with historical data, the shallow groundwater flow and the COC plume
extends to the west toward the unnamed intermittent stream.
• A bioenhancement agent (EOSO) was injected into 70 shallow source area injection wells
in August and September 2011. Post -injection data collected in October 2011 and
January 2012 indicate that TCE and 1,1,1-TCA concentrations are decreasing in plume
wells MW-9 and MW-13. These trends indicate that the EOS® injection has resulted in
enhanced bioremediation within portions of the ground water plume area. Concentration
trends will continue to be evaluated during future sampling events.

In accordance with the UIC permit, H&H recommends continuing performance monitoring to
include two years of post -injection quarterly sampling to evaluate the effectiveness of the EOS®
injection at reducing groundwater concentrations. The third monitoring event was completed in
April 2012 and the fourth monitoring event is scheduled for July 2012. A second injection
performance evaluation report will be submitted to DENR following the July 2012 event, which
will present the results of the third and fourth quarterly sampling events, an updated evaluation of
the effectiveness of the enhanced biodegradation, and recommendations for future monitoring
and/or site activities.

Good Morning Tripp,
We received your samples on Friday for Metabolic Acids and I have a few questions — can you please tell me what type of
report your client requires and if an EDD is needed? (1-2, L3, etc.)
I would appreciate it if you can please let me know as soon as possible.
Thank you!

Hi Kevin
The coc for this project is asking for AM216 VFAs but the vials we reed are for our AM23G VFAs. We do not want to
run those preserved vials on the instrument. Would you be OK with AM23G? They have lower reporting limits. See
attached.
