Post Injection Groundwater Monitoring Report
Former Preslar's Exxon
Midland, Cabarrus County, NC
1.0 INTRODUCTION
Solutions-IES Project No. 2014.0009.NDOT
NCDOT WBS # 34348.3.5
January 8, 2016
Solutions-IES, Inc. (SIES) has completed an initial injection event to implement the approved
groundwater remediation program at the Former Preslar's Exxon Site (Site) located at 901 NC Hwy 24/27
in Midland, Cabarrus County, North Carolina (Figure 1). This Post Injection Groundwater Monitoring
Report has been prepared for the North Carolina Department of Transportation (NCDOT) Geotechnical
Engineering Unit and the North Carolina Department of Environmental Quality (NCDEQ; formerly the
North Carolina Department of Environment and Natural Resources) Water Quality Section to document
the post -injection monitoring at the Site in accordance with Underground Injection Control (UIC) Program
Permit No. W10300282.
1.1 SITE BACKGROUND
The former owners operated the Site as a convenience store and gasoline station from 1968 to 1994
(S&ME, 2001). The underground storage tank (UST) system at the former station consisted of four USTs
and one pump island with associated product dispensers. The NCDOT purchased the property from Mr.
Walter Preslar in 1994, and removed the USTs from the Site during tank closure activities in January
1995. The NCDOT demolished the remaining building on site shortly after the tank closure activities to
accommodate widening NC Highway 24/27. After road construction was finished, the grass median
between the eastbound and westbound lanes of NC Highway 24/27 contained the former UST basin
(Figure 2). In August 1995, S&ME, Inc. (S&ME) completed a receptor survey that identified 13 water
supply wells located within 1,500 feet of the site.
Thirteen monitoring wells identified on Table 1 and shown on Figure 2 have been installed at the Site
since the USTs were removed in 1995. S&ME completed a Comprehensive Site Assessment (CSA) in
August 2001 (S&ME, 2001) that identified petroleum contamination in groundwater originating from a
probable source area near the former gasoline USTs. A CSA addendum by S&ME (January 2002)
completed the groundwater plume delineation (S&ME, 2002a). A second addendum by S&ME in
November of 2002 completed the soil contamination delineation (S&ME, 2002b).
The CSA reported detections of petroleum constituents above 15A NCAC 2L 0.0202 Groundwater
Standards (NC 2L Standards) in four of the 13 monitoring wells: MW-1, MW-3, MW-4, and MW-5. The
petroleum constituents exceeding the NC 2L Standards included benzene, ethylbenzene, toluene, total
xylenes, methyl-tert-butylether (MTBE), isopropylether (IPE), naphthalene, C5-C8 aliphatics, C9-Cl8
aliphatics, and C9-C22 aromatics.
The analyses also detected halogenated organic compounds above NC 2L Standards in groundwater
samples collected from monitoring wells MW-3, MW-6, MW-7 and MW-8 located south of NC Highway

24/27. The halogenated compounds exceeding their groundwater standards included chloroform,
bromodichloromethane, and dibromochloromethane. The presence of these trihalomethanes in the
groundwater was presumed to be the result of well construction activities that used treated municipal
water in the well construction process. The City of Concord 2003 Annual Water Quality Report showed
that treated municipal water contained trihalomethanes that exceed the NC 2L Standards. Analysis also
detected trihalomethanes in the sample from water supply well WSW-12 in excess of the NC 2L
Standards, suggesting that the well may have been disinfected with a chlorinated chemical during 2002.
The chemical 1,2-dichloroethane (1,2-DCA) was identified during one sampling event at WSW-10, but no
other events. The CSA concluded that the presence of halogenated compounds in the water supply wells
near the site was not likely related to the petroleum -release incident at the project site.
In March 2005, SIES prepared a Corrective Action Plan (CAP) for the NCDEQ UST Section, Mooresville
Regional Office (MRO), that recommended in situ chemical oxidation (ISCO) using an iron- and steam -
activated sodium persulfate injection as the remediation alternative. From 2005 to 2012, the NCDOT
made attempts to reduce the risk classification of the site by abandoning nearby water supply wells and
irrigation wells within 1000 feet of the source area. However, a replacement well for one of the closer
irrigation wells did not yield sufficient water for the owner's use, so the original irrigation well could not be
abandoned and reclassification was not an option. In May 2012, SIES prepared a CAP Addendum with
an updated evaluation of ISCO using sodium persulfate compared to sulfate -mediated anaerobic
oxidative bioremediation using EAS° and soil vacuum extraction/air sparging. The CAP Addendum
recommended switching to sulfate -mediated anaerobic bioremediation as the preferred groundwater
remedy. The UST Section MRO issued a Notice of Regulatory Requirements (NORR) to NCDOT dated
August 14, 2012, requesting results of pilot testing of the EAS° technology before completing their review
of the addendum. SIES implemented the pilot test in June 2012, and submitted the EAS Technology
Evaluation Report (SIES, 2013) on January 23, 2013. The UST Section MRO provided tentative approval
of the CAP Addendum by way of an NORR dated August 14, 2013.
On March 31, 2015, the NCDOT received Injection Permit W10300282 from the NCDEQ Division of Water
Resources (DWR) UIC Program for the installation of 21 injection wells and approval to inject EAS°
substrate into the groundwater at the Site. As part of the permit, a baseline groundwater monitoring event
was required within 30 days prior to injecting the substrate. Beginning April 27, 2015, SIES and its
subcontractor American Environmental Drilling, Inc. (AEDI), installed 19 permanent injection wells at the
site. Two previously installed pilot study wells were used as injection wells, which brought the total
number of injection wells to 21. On May 4 and 5, 2015, SIES conducted a baseline monitoring event for
13 monitoring wells and two water supply wells. Following the baseline monitoring, a full-scale injection
event was performed on May 18 to 20, 2015, in which 1,113 gallons of EAS°were injected (SIES, 2015).

On November 16-17, 2015 SIES conducted the 6-month post injection sampling event, which is the third
of four post -injection groundwater monitoring events required by the injection permit. This report
describes the field activities and results of those monitoring events.
2.0 POST INJECTION GROUNDWATER MONITORING PLAN
In accordance with the injection permit, the post injection monitoring plan was designed to sample and
analyze the 13 monitoring wells and four water supply wells. During previous sampling events, these
water supply wells included WSW-9, WSW-10, WSW-11, and WSW-12. However, no access
agreements were in place to sample the off -site wells WSW-9, WSW-10, and WSW-12. In June 2015,
SIES, on behalf of the NCDOT, requested the landowners to grant access. On June 22, 2015, SIES
received an access agreement from the landowner for WSW-10. No other access agreements were
received. SIES notified the NCDEQ that the lack of access agreements would not allow the sampling of
WSW-9 and WSW-12. The NCDEQ attempted to obtain access agreements from the well owners, but
after failing to acquire access agreements for these wells, the injection permit was modified to include
sampling of supply wells WSW-10 and WSW-11, only.
Four post injection monitoring events were required as part of the injection permit; one month, three
months, six months, and one year following the injection event. SIES conducted the one -month (June
2015), three-month (August 2015), and six-month (November 2015) events, which are the subject of this
report. The one-year monitoring, which has not taken place, is scheduled for 12 months following the last
inject event. The remainder of this section will outline the general procedures for the sampling and
describe specifics for each event.
2.1 GROUNDWATER ELEVATIONS
Prior to collecting groundwater level measurements, SIES personnel opened each monitoring well to
allow the water level to equilibrate. Field personnel used an electronic water level indicator to measure
water levels. The depth -to -water measurements were converted to elevations by subtracting the depth -
to -water measurement from the top -of -casing elevation provided by a NCDOT survey. Table 1 presents
the post injection water level data with historical water level measurements.
The groundwater elevation data for wells screened in the shallow aquifer were used to develop shallow
potentiometric surface maps for the baseline, June, August, and November 2015 events, as shown on
Figure 3. The groundwater contour maps suggest that shallow groundwater generally flows to the
southeast, which is similar to previous findings. However, because bedrock was encountered at a depth

of about 4 to 6 feet below ground surface (ft bgs), groundwater flow may be fracture -controlled and
variations to the apparent flow direction may be present.
2.2 GROUNDWATER SAMPLING
After measuring the water level in each monitoring well, SIES collected groundwater samples using low -
flow purging methods. During the purging, personnel recorded field parameters (Appendices A through
C; Table 2), including pH, temperature, specific conductivity, dissolved oxygen (DO), and oxidation-
reduction potential (ORP) until each parameter stabilized or until the wells were nearly purged dry. Prior
to collecting the water samples at water supply wells WSW-9 and WSW-11, the pumps in the water
supply wells were turned on and left running for approximately 15 minutes to purge the well.
After purging, a groundwater sample was collected from each monitoring well with the peristaltic pump
and transferred to laboratory -supplied bottles. The groundwater samples from the water supply wells
were collected from spigots directly into the bottles. The samples were stored on ice under chain -of -
custody control and transported to Pace Analytical Services (Pace Lab) in Huntersville, North Carolina for
analysis of sulfate by EPA Method 300.0 and 601/602 volatile organic compounds (VOCs) by SM 6200B.
2.3 GROUNDWATER MONITORING RESULTS
Table 3 summarizes the results of the target compounds detected in the baseline and post injection
sampling events and Table 4 summarizes the historical target compounds results. The applicable NC 2L
Standards are included for comparison. The laboratory analytical reports for the post injection sampling
are provided in Appendices D through F.
As shown in Table 3, VOCs were detected in four wells at the site; shallow wells MW-1, MW-4, and MW-
13, and deep well MW-5. No other well samples contained detectable VOCs. Of the compounds
detected, benzene in the sample from MW-1, and benzene, ethylbenzene, total xylenes, and naphthalene
in the samples from MW-4 and MW-13 were detected at concentrations above the respective NC 2L
Standards. The concentrations of the these compounds in samples from wells MW-1 and MW-13
followed a similar pattern; a significant decrease from the baseline to the one -month sampling event,
followed by a rebound at month three and a subsequent reduction in month six. The samples from well
MW-4, the samples with the highest concentrations, showed a consistent increase over time with a slight
reduction in month six. Figure 4 presents an interpretation of the lateral extent of benzene impacts
identified in the shallow groundwater over time. The benzene detected in deep well MW-5 is anomalous
in that historically, no VOCs have been detected consistently. The analyses for water supply wells WSW-
10 and WSW-11 did not detect VOCs in either well sample.

The laboratory conducted sulfate analysis on all the groundwater samples collected for the sampling
events. For the baseline concentrations, sulfate in all the well samples ranged from 3.3 to 64.4 milligrams
per liter (mg/L). The post -injection sulfate concentrations increased at the one -month interval in the
samples from wells MW-1, MW-4, and MW-13. The laboratory reports indicate that the sulfate
concentration in well MW-1 increased to 461 mg/L, which is above the NC 2L standard of 250 mg/L,
decreased to 210 mg/L in month three, and increased to 313 mg/L in month six. For well MW-4, the
sulfate increased in month one, but decreased to below the detection limit in months three and six. For
well MW-13, the sulfate increased in months one and three, but decreased to its baseline concentration in
month six. These relationships are demonstrated on the charts in Appendix G.
Wells MW-3, MW-9, and MW-10, located near the contaminated wells, exhibited an increase in sulfate in
month one with a decrease to baseline concentrations by month six. No other wells exhibited a sulfate
increase or decrease post injection.
3.0 GROUNDWATER REMEDIATION EVALUATION
As approved in the CAP Addendum, groundwater remediation was conducted by injection of EAS° sulfate
solution into the groundwater and monitoring the groundwater to evaluate the effectiveness of the
remediation effort. The objective of injecting sulfate into groundwater was to stimulate indigenous sulfate -
reducing bacteria to biodegrade the residual petroleum constituents. The goal of the remediation was to
reduce the petroleum constituents of concern in the groundwater to concentrations below the NC 2L
Standards. Effectiveness of the EAS° treatment can be evaluated by comparing the VOC concentrations
post injection to those at baseline; noting the depletion of sulfate versus the VOC concentrations; and
observing the migration of the benzene contaminant plume.
As indicated on Table 3, wells MW-1, MW-4, and MW-13 were designated as injection performance
monitoring wells. A comparison of the VOC concentrations over time in these wells provides a basis for
evaluating the remediation method.
MW-1— Analysis of samples from well MW-1 indicated benzene as the only compound detected
above the NC 2L Standard. Following injection, the benzene concentration decreased at one
month, rebounded to the baseline level at month three, and decreased again to slightly above the
NC 2L Standards at six months.
MW-4 — Analysis of samples from well MW-4 indicated benzene, ethylbenzene, total xylenes, and
naphthalene as the compounds detected above their respective NC 2L Standard. All of these
compounds followed a pattern of increasing above the baseline concentration over the first three
months and decreasing slightly at the six-month interval. At the six-month interval, all these
compounds were detected above the NC 2L Standards.
MW-13 — Analysis of samples from well MW-13 indicated benzene, ethylbenzene, total xylenes,
and naphthalene as the compounds detected above their respective NC 2L Standard. All of
these compounds followed a pattern of decreasing at one month, rebounding to the baseline level

at month three, and decreasing again at six months. At the six-month interval, ethylbenzene and
total xylenes decreased to below the NC 2L Standards.
Although many of the compounds discussed above were above the NC 2L Standards at the end of six
months, an overall decreasing trend was observed, which suggests that the sulfate injection is influencing
the groundwater impacts.
The injection effectiveness can also be evaluated by comparing the changes in sulfate concentrations
with VOC concentrations. In theory, the consumption of sulfate will result in a corresponding decrease in
contaminants. For evaluation purposes, benzene concentrations in each well were evaluated against the
sulfate concentrations.
MW-1— Benzene was detected at relatively low concentrations in this well. The sulfate
concentration increased an order of magnitude above the baseline concentration of 35.3 mg/L
and remained high (210 to 461 mg/L) after that. After six months, the benzene concentration
decreased from 15 to 4 pg/L. This suggests that sulfate concentrations may remain higher
because little contamination is present.
MW-4 — Benzene was detected at its highest concentration at the site in this well. From a
baseline concentration of 503 pg/L, benzene increased over three months to 960 pg/L and
subsequently decreased to 419 pg/L. Correspondingly, the baseline sulfate concentration of 3.3
mg/L increased to 19.5 mg/L, but decreased to below detection limits in months three and six.
This suggests that the high concentrations of contamination have rapidly depleted the sulfate.
MW-13 — Benzene was detected in the site midrange concentration in this well. From a baseline
concentration of 88.4 pg/L, it decreased to 40.8 pg/L at one month, increased to 171 pg/L at three
months, and decreased to 15.3 pg/L at six months. By comparison, sulfate increased from its
baseline concentration of 7.5 mg/L to 33.6 mg/L at the first month. It continued to increase to 53.8
mg/L at the three-month interval and decreased sharply to 6.2 mg/L at six months. This suggests
a general correlation between sulfate and VOC reductions.
From the comparison of sulfate and VOC concentrations, the analytical results suggest that sulfate
concentrations are influencing VOC attenuation.
The overall effectiveness of the remediation effort can be evaluated from the plume size and migration
changes. Figure 4 shows the benzene plume map for the baseline and subsequent monitoring events.
Based on this map, the plume size decreased slightly over time and is not migrating. Lack of migration
over time suggests attenuation at the plume edges.
4.0 CONCLUSIONS
The petroleum source area for the Site is currently located in the median of NC Highway 24/27. The
contaminant plume encompasses the source area as well as a small area along the eastbound right-of-
way. Based on the laboratory results presented in Table 3 and the discussion above, the primary
constituents above the NC 2L Standards are limited to benzene, ethylbenzene, total xylenes, and

naphthalene. Although other VOCs have been detected, their concentrations are below the NC 2L
Standards. Based on the available data, shallow groundwater appears to flow to the southeast.
The analytical results for VOCs and sulfate suggest that the injection influenced attenuation of the
contaminants. The results also indicate that sulfate has been reduced within the plume and additional
injections are warranted. As a result, SIES recommends two additional injection events at six-month
intervals for 2016.
