EOS° Injection and Semi -Annual
Groundwater Monitoring Report
Former ATL Site No. 2-66
Statesville, North Carolina
H&H Job No. DOT-504
1.0 Introduction
On behalf of the North Carolina Department of Transportation (DOT), Hart & Hickman, PC
(H&H) has prepared this report to present post -injection groundwater monitoring data for the
former Asphalt Testing Laboratory Site No. 2-66. The site is located at 164 Bostian Bridge
Road, which is near Buffalo Shoals Road (State Road 1004) in Statesville, North Carolina
(Figure 1). A site map is provided as Figure 2.
Soil and groundwater. impacts from former asphalt testing operations 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 (NINA) for groundwater impacts. Approximately 162 tons of
impacted soils were removed from the source area in September 2001 as reported in H&H's
Semi -Annual Monitoring and. Soil Remediation Report dated February 19, 2002. Confirmation
soil samples indicated that soils were adequately removed. Monitored natural attenuation,
consisting. of semi-annual or annual groundwater monitoring,. was conducted at the site from
2002 until prior to the bioenhancement injection in December 2012.
Because TCE concentrations remained more than two orders of magnitude above the
groundwater standard, a stream is located near the plume, and there is no public water available
in the area of the site, H&H recommended that the bioenhancement event be conducted in
shallow groundwater where TCE concentrations were the highest. Bioenhancement improves
subsurface conditions for more efficient natural attenuation by reductive dechlorination.
On behalf of DOT, H&H prepared an Underground Injection Control (UIC) Permit Application
dated August 24, 2012 to conduct a bioenhancement injection at the site. The injectant selected

for the bioenhancement injection event was Emulsified Oil Substrate (EOS®). The North
Carolina Department of Environmental Quality (DEQ) issued the UIC permit on November 9,
2012. The bioenhancement injection activities were conducted in December 2012.
The injection event included 36 temporary direct push technology (DPT) injection points and
injecting the EOS® into the upper 20 ft of the saturated zone. The 36 temporary DPT injection
wells . were installed approximately 20 ft apart perpendicular to . groundwater flow and
approximately 35 ft apart parallel to groundwater flow within the target treatment area. The DPT
temporary injection wells were advanced to depths ranging from approximately 27 ft to 42 ft
below ground surface (bgs). The injection area and injection .well locations are depicted on
Figure 4.
The EOS® concentrate was mixed with water prior to injection using an approximate mixing
ratio of 1:6 (EOS® to water). For the project, a total of approximately 1,618 gallons of EOS®
concentrate were' mixed with approximately 10,666 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 323 to 508 gallons of diluted EOS® mixture
were injected into each injection well.
This post -injection semi-annual groundwater monitoring report includes a summary of post -
injection groundwater monitoring between March 2015 and February 2016.

2.0 Potential Receptor Survey Update
A summary of area receptors is described below and was updated in October 2015. The next
annual receptor survey update will be conducted in the second half of 2016.
2.1 Water Supply Wells
The October 2015 receptor survey update was performed by reconnaissance within 1,500 ft of the
former asphalt -testing laboratory and by contacting the local utility department to confirm that no
municipal wells are in the area. During the October 2015 receptor update, no additional water
supply wells were identified within 1,500 ft of the site.
A total of 18 water supply wells (active, inactive, or abandoned) are located within a 1,500-ft
radius of the former asphalt -testing laboratory. The locations of the water supply wells are
indicated on Figure 3, and a summary of water supply well information is provided in Table 1.
Of the 18 water supply wells, four wells are located on -site and are designated as WSW -I,
WSW-2, WSW-4, and WSW-4A. In accordance with the approved CAP, H&H abandoned water
supply wells WSW-1 and WSW-2 in September 2001. Water supply wells WSW-4 (deeper) and
WSW-4A (shallow) are located approximately 500 ft southeast and upgradient of the source area. .
WSW-4 serves the entire subject property and WSW-4A is inactive. Target volatile organic
compounds (VOCs) have not been detected in WSW-4 including during the most recent
sampling event in February 2016 (Table 2).
No off -site water supply wells are located downgradient of the former asphalt -testing laboratory.
Each of the 14 off -site water supply wells is located upgradient or cross*gradient of the former
asphalt laboratory. The closest off -site water supply well (WSW-5) is situated cross -gradient of
the site approximately 650 ft southwest of the former asphalt laboratory.
One of the 14 off -site water supply wells (WSW-3) is located cross -gradient of the former
asphalt -testing laboratory on the Dorothy Davis property (across an unnamed tributary of
Third Creek and approximately 1,200 ft northeast of the former laboratory). WSW-3 was

sampled in September 1997 and again in October 1998. No target compounds were identified in
either sample. Further, a deep saprolite monitoring well (DMW-8), located on the same side of
the tributary as WSW-3, is not impacted. The lack of impacts in DMW-8 indicates that the
tributary acts as an effective hydraulic barrier.
Based on the distance from the former laboratory, the known extent of the contaminant plume,
and topographic and hydraulic gradient considerations, the potential for site groundwater impacts
to affect the off -site water supply wells is considered to be low.
2.2 Surface Water
Two surface water bodies are located within a 0.25-mile radius of the subject site (Figures 1
and 3). An unnamed tributary to Third Creek is located approximately 400 ft north of the former
laboratory and borders the northern property boundary. In addition, Third Creek is located
approximately 600 ft west of the former laboratory and borders the western property boundary.
Both of these surface water bodies appear to be discharge locations for site groundwater.
In February 1999, surface water samples were collected from both the unnamed tributary and
Third Creek at locations along the northern and western properly boundaries of the site. In
addition, H&H collected a surface water sample (labeled SS-2) in October 2015 and February
2016 from the unnamed tributary of Third Creek (Table 4 and Figure 2). The surface - water
samples were analyzed for purgeable halocarbons by EPA Method 6200B. Target compounds
were -not detected in the surface water. samples. In addition, groundwater modeling conducted as
part of the CAP indicates that target compounds will not be present in these surface waters above
surface water quality standards in the future. Recent surface water sampling activities are
discussed further in Section 3.

3.0 Groundwater/Surface Water Monitoring
As outlined in the UIC permit, H&H conducted pre -injection groundwater monitoring events on
February 2 and 3, 2012 and December 7, 2012 to establish a baseline for comparison with post -
injection monitoring data. Additionally, H&H performed quarterly post -injection monitoring
events in February 2013, April 2013, June 2013, October 2013, January 2014, May 2014, July
2014, November 2014, and February 2015 to assess the performance of the implemented enhanced
bioremediation remedy. The April 2013, October 2013, May 2014, and November 2014 quarterly
sampling events were comprehensive events as outlined in the UIC permit application. In
accordance with the UIC permit, the groundwater monitoring schedule was reduced from
quarterly to semi-annually following the February 2015 quarterly post -injection monitoring event.
The groundwater sampling procedures and monitoring results for the October 2015 and February
2016 monitoring events 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.
3.1 Data Collection Procedures
In October 2015 and February 2016, H&H sampled deeper saprolite monitoring wells DMW-1,
DMW-2, DMW-3, DMW-6, DMW-8, DMW-9, DMW-10, and DMW-11 and bedrock
monitoring well DMW-7. Samples from these wells were submitted for laboratory analysis of
VOCs by Environmental Protection Agency (EPA) Method 6200B (reporting the EPA Method
601 list), Resource Conservation and Recovery Act (RCRA) metals (arsenic, barium, cadmium,
chromium, lead, selenium, silver, and mercury). Due to the extensive amount of natural
attenuation data collected during the post -injection quarterly performance monitoring, natural
attenuation parameter sampling were reduced to select measurements including dissolved oxygen
J (DO), oxidation-reduction potential (ORP), specific conductivity, pH, and temperature, and
laboratory analysis of total organic carbon (TOC). In addition, one surface water sample was
collected from the unnamed tributary of Third Creek located north of the site for laboratory
analysis of VOCs by EPA Method 6200B (reporting the EPA Method 601 list).

The sampling events were conducted using the following procedures. After monitoring well
water levels were gauged, DO concentrations were measured using a downhole probe. Following
DO measurements and prior to collection of groundwater samples, the target wells were purged
using dedicated disposable bailers until pH, temperature, and specific conductivity levels
stabilized. If a well went dry during purging, the purging process was considered to be complete.
Groundwater samples were collected with dedicated disposable bailers.
Groundwater samples were submitted for laboratory analyses of VOCs using methods listed
above. Pace Analytical Laboratories, Inc., a North Carolina -certified laboratory, conducted the
laboratory analyses. 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 A.
3.2 Groundwater Levels and Flow Direction
Water levels in site monitoring wells were gauged using an electronic water level meter on
October 22, 2015 and February 16, 2016 (Table 3). The estimated saprolite potentiometric map
constructed from the February 2016 groundwater elevation data is presented as Figure 5. The
potentiometric map was constructed using both shallow and deeper saprolite water levels.
Consistent with previous data, groundwater flow in the saprolite aquifer is generally to the
northwest in the direction of Third Creek. and its tributary. The shallow groundwater has a
calculated horizontal hydraulic gradient of approximately 0.04 ft/ft.
3.3 Surface Water Measurements and Analytical Data
As required in the UIC permit, during the two years of post -injection quarterly performance
monitoring, surface water measurements were collected from the unnamed tributary of Third
Creek at locations upstream-(SS-1) and downstream (SS-2) of the injection area to determine if

- the bioenhancement injection activities were adversely impacting the creek. The locations of SS-
1 and SS-2 are depicted on Figure 2. Based on similar data between the two locations during
each sampling event, the bioenhancment injection did not adversely impact the tributary (Table
8).
A surface water sample was collected for VOC analysis from the unnamed tributary of Third
Creek at a location (SS-2) downgradient of the injection area on October'22, 2015 and February
16, 2016. The samples were collected by lowering a bailer into the flowing stream. No VOCs
were detected in the surface water samples (Table 4).
3.4 Groundwater Analytical Data
October 2015 Semi -Annual Sampling Event
Deeper Saprolite
Analytical results from the October 2015 sampling event indicate groundwater impacts above
groundwater standards in deeper saprolite monitoring wells DMW-6 and DMW-11 (Table 5).. TCE
and 1,1-dichloroethane were the only two compounds detected above groundwater standards. The
most elevated concentrations were detected in DMW-6. TCE was detected in monitoring well.
DMW-6 at a concentration of 33.7 µg/l, which is above the groundwater standard for TCE of 3
µg/l. 1,1-DCA was detected in monitoring well DMW-6 at a concentration of 41.9 µg/1, which is
above the groundwater standard for of 6 µg/l.
Consistent with previous . sampling events, target compounds were not detected in deeper
saprolite well DMW-8. Monitoring well DMW-8 is situated on the northern side of the unnamed
tributary of Third Creek. The absence of groundwater impacts in DMW-8 indicates that the
tributary is acting as an effective hydraulic barrier.

Bedrock
In October 2015, target compounds were not detected above laboratory reporting limits in bedrock
wells DMW-3,.DMW-4, and DMW-7 (Table 6), or in the on -site water supply well WSW-4 (Table
2). Bedrock well DMW-7 is located adjacent to deep saprolite well DMW-6, which is the
monitoring well with the highest target compound concentrations. Although only approximately 25
ft separates the DMW-6 and DMW-7 well screens, the concentrations decrease with depth to non -
detectable levels in DMW-7.
February 2016 Semi -Annual Sampling Event
Deeper Saprolite
Analytical results from the February 2016 sampling event indicate groundwater impacts above
groundwater standards in deeper saprolite monitoring wells DMW-6 and DMW-11 (Table 5 and
Figure 6). TCE and 1, 1 -dichloroethane were the only two compounds detected above groundwater
standards: The most elevated concentrations were detected in DMW-6. TCE and .1,1-DCA were
detected in monitoring well DMW-6 at concentrations of 28.4 µg/1 and 34.5 µg/l, respectively.
These concentrations are above the groundwater standards for TCE and 1,1-DCA.
As in October 2015, target compounds were not detected in deeper saprolite well DMW-8. As
stated above, the absence of groundwater impacts in DMW-8 indicates that the tributary is. acting
as an effective hydraulic barrier.
Bedrock
i'
In February 2016, target compounds were not detected above laboratory reporting limits in bedrock
wells DMW-3, DMW-4, and DMW-7 (Table 6 and Figure 7), or in the on -site water supply well
WSW-4 (Table 2).

Concentration Trends
TCE is the most widespread target VOC detected above standards. Post -injection February 2016
data indicate that TCE levels have decreased from 68.5 µg/l to 28.4 µg/1 in DMW-6, 3.3 µg/1 to 2
µg/l in DMW-9, and 10.8 µg/l to 4.1 µg/l in DMW-11 since the injection in 2012..These trends
indicate that the EOS® injection has resulted in enhanced bioremediation to some extent.
Concentration trends will continue to be evaluated during future sampling events.
Concentrations of key VOCs in saprolite and bedrock groundwater are depicted on Figures.6
and 7. A graph showing the showing the TCE concentration trend in monitoring well DMW-6 is
provided in Appendix B.

- 4.0 Evaluation of Natural Attenuation Parameters
Natural attenuation of groundwater 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 potential 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 was 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 general favorable results in concentrations trends are being observed since the
injection of EOS® in December 2012. Recent and historical biodegradation data are presented in
Table 7. A discussion of the recent indicator parameter data from February 2016 is provided
below.
4.1 Indicators of Reductive Dechlorination
Various electron acceptors can potentially compete with reductive dechlorination, including DO,
nitrate, sulfate, ferric iron, 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. As previously indicated, natural attenuation parameter
sampling was reduced to select field measurements of DO, temperature, pH, ORP, and laboratory
analysis of TOC. At the request of DEQ, site wells also were sampled for eight RCRA (metals
arsenic, barium, cadmium, chromium, lead, selenium, silver, and mercury). A summary of these
data and recent previous natural attenuation indicator and target COC data are provided in Table

7. A brief discussion of the recent indicator parameter data from February 2016 are 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
close to or less than 1 mg/l are favorable.
Dissolved oxygen measurements ranged from 0.84 mg/1 (DMW-9) to 3.91 mg/1 (DMW-4) in
February 2016. Monitoring- wells with dissolved oxygen levels close -to or less than 1.0 mg/1
included monitoring wells DMW-2, DMW-8, and DMW-9. The measured dissolved oxygen
concentrations in most impacted monitoring wells indicate conditions conducive for reductive
dechlorination to occur.
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 -110 mV (DMW-4) to 451 mV (DMW-1) in February 2016. 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 six to eight 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. Groundwater pH ranged from 4.98 to 12.3.5 in February 2016. In

SMARTEN ENNRONSM1ENiILL SOUfRONS

i
impacted wells DMW-6 and DMW-11, the pH is above 6.0. The site pH values are within or
- close to the range, which is considered favorable for reductive dechlorination. Certain wells will
high pH may indicate that pH has been inadvertently increased by the grout used to install the
well.
Temperature does not greatly influence reductive dechlorination, but temperatures greater than
20°C. may accelerate biochemical processes. In February 2016, temperatures ranged from 12.7°C
to 17.6°C. The average groundwater temperature for the site is approximately 16°C. These
temperatures are in the range, which is considered satisfactory for biodegradation.
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 ,February 2016, TOC levels ranged from 1.3 mg/l
(DMW-8) to 20.9 mg/l (DMW-10). The TOC levels near the injection area appear to have been
enhanced by the injection. H&H will continue to will monitor for the presence of TOC in other
portions of the plume during future monitoring events.
RCRA Metals
In February 2016, the RCRA metals barium, chromium, and lead were detected in select site
wells above pre -injection metals concentrations detected in December 2012. The RCRA metal
concentration increases may be associated with elevated turbidities noted in the monitoring wells
in the past. Additionally, because RCRA metal concentration increases were also noted in
monitoring wells located greater than 100 ft upgradient of the injection area, the increases do not
appear to be related to the 2012 bioenhancement injection. RCRA metals will continue to be.
evaluated during future sampling events.

4.2 Presence of Degradation Daughter Products
Degradation or 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-dicholoroethene (cis
1,2-DCE) provide direct evidence that biodegradation by reductive dechlorination of the parent
VOCs has occurred. In general, daughter product concentrations continue to be present in higher
concentrations relative to parent products. The continued presence of these daughter products
indicates that reductive dechlorination is occurring.
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
presence of significant 1,1-DCE concentrations compared to TCA in well DMW-6 indicates that
abiotic degradation of TCA is also occurring in the plume area.

5.0 Summary and Conclusions
H&H has implemented an enhanced bioremediation remedy and completed the pre -injection
_ baseline and quarterly post -injection performance monitoring events at the former Asphalt
Testing Laboratory Site No. 2-66 in Statesville, NC. The purpose of the remedial action was to
enhance biodegradation of chlorinated solvents in groundwater.
The pre -injection baseline monitoring event was completed in February/December 2012 and
H&H completed two years of post -injection quarterly performance monitoring in February 2015.
Following the final quarterly post-EOS injection monitoring event in February 2015, H&H
initiated semi-annual groundwater monitoring to evaluate the movement of target COCs in site
groundwater and to provide additional data in support of the enhanced bioremediation remedy.
The most recent semi-annual monitoring event was completed in February 2016. The following
summarizes the results of the February 2016 semi-annual sampling event and continued
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 two deeper saprolite monitoring wells. No
impacts above standards were detected in bedrock monitoring wells.
• No ground water impacts were detected in monitoring well DMW-8 located on the opposite
side of the unnamed tributary of Third Creek from the former asphalt -testing laboratory.
The absence of ground water impacts in DMW-8 indicates that the tributary is acting as an
effective hydraulic barrier.
• Target compounds were not detected in the active, upgradient on -site water supply well or
in the unnamed tributary of Third Creek in October 2015 and February 2016.

• The bioenhancement agent (EOS®) was injected into 36 injection wells in December
2012. Post -injection data collected most recently in February 2016 indicate that TCE
concentrations are decreasing in plume wells DMW-6, DMW-9, and DMW-11. These
trends indicate that the EOS® injection has resulted in enhanced bioremediation within
portions of the groundwater plume area. Concentration trends will continue to be
evaluated during future sampling events.
H&H reduced the groundwater monitoring schedule from quarterly to semi-annually beginning
in February 2015. During the sampling event, groundwater samples will be collected from
deeper saprolite monitoring wells DMW-1, DMW-2, DMW-6, DMW-8, DMW-9, DMW-10, and
DMW-11; and bedrock monitoring wells DMW-3, DMW-4, and DMW-7. _
