March 2016 Groundwater Monitoring and Injection Event Report Solutions-IES Project No. 2014.0009.NDOT
Former Preslar's Exxon NCDOT WBS # 34348.3.5
Midland, Cabarrus County, NC May 18, 2016
1.0 INTRODUCTION
Solutions-IES, Inc. (SIES) is continuing 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 March 2016 Groundwater Monitoring and Injection Event Report has been
prepared for the North Carolina Department of Transportation (NCDOT) Geotechnical Engineering Unit to
document the groundwater conditions in accordance with Underground Injection Control (UIC) Program
Permit No. WI0300282. It describes the activities and results of the groundwater sampling event that took
place in March 2016 and a summary of the injection event conducted in April 2016.
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 (Table 1 and Figure 2) have been installed at the Site since the USTs were
removed in 1995. A Comprehensive Site Assessment (CSA) completed in August 2001 (S&ME, 2001)
identified petroleum contamination in groundwater originating from a probable source area near the
former gasoline USTs. A CSA addendum in January 2002 completed the groundwater plume delineation
(S&ME, 2002a). S&ME completed the soil contamination delineation and prepared a second addendum
in November 2002 (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).
Benzene, ethylbenzene, toluene, total xylenes, methyl -tert-butylether (MTBE), isopropylether (IPE),
naphthalene, C5-C8 aliphatics, C9-C18 aliphatics, and C9-C22 aromatics exceeded the NC 2L Standards
in one or more of the monitoring wells.
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 chloroform, bromodichloromethane, and dibromochloromethane

exceeded their groundwater standards. These trihalomethanes in the groundwater were presumed to be
the result of well construction activities that used treated municipal water in the well construction process.
The City of Concord serves this area and their 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. 1,2-
Dichloroethane (1,2-DCA) was identified during one sampling event at WSW-10, but in 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 North Carolina Department of
Environment and Natural Resources, now the North Carolina Department of Environmental Quality
(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 EASO1 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 approval of the CAP Addendum in a 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. In April 2015, 19 permanent injection wells were installed at
the site. Two previously installed pilot study wells were used as injection wells, which brought the total
number of injection wells to 21. The initial full-scale injection event was performed on May 18 to 20,
2015, in which 1,113 gallons of EAS°were injected (SIES, 2015). Following the injection, SIES
conducted post -injection groundwater monitoring events at 1-, 3-, and 6-month intervals. The analytical
' EAS° is an aqueous solution of sulfate salts and nutrients available commercially from EOS Remediation, LLC in
Raleigh, NC.

March 2016 Groundwater Monitoring and Injection Event Report Solutions-IES Project No. 2014.0009.NDOT
Former Preslar's Exxon NCDOT WBS # 34348.3.5
Midland, Cabarrus County, NC May 18, 2016
results indicated that petroleum compounds were decreasing in the 1- and 3-month intervals, but had
increased to pre -injection concentrations at the 6-month interval. Based on these results, SIES and
NCDOT requested approval to conduct a second injection event.
In a NORR dated January 28, 2016, the NCDEQ requested that the NCDOT conduct an additional
groundwater sampling event prior to approval of a second injection. The sampling request was the result
of increased sulfate in the on -site irrigation well (WSW-11)approaching the NC 2L Standard. The
NCDEQ asserted that if sulfate concentrations continued to increase in the well, additional injections may
not be approved. This report describes the field activities and results of the requested monitoring event.
2.0 GROUNDWATER MONITORING
The monitoring plan, as approved in the injection permit, requires sampling at the 13 monitoring wells and
two water supply wells (WSW-9 and WSW-1 1).
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 that was surveyed by the NCDOT. Table 1
presents the March 2016 water level data and previous water level measurements.
The groundwater elevation data for wells screened in the shallow aquifer were used to develop a shallow
potentiometric surface map for March 2016 (Figure 3). The groundwater contour map suggests 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 ft bgs, groundwater flow may be fracture -
controlled and variations to the apparent flow direction may be present.
2.2 GROUNDWATER SAMPLING
SIES collected groundwater samples using low -flow purging methods after measuring the water level in
each monitoring well. While purging, personnel recorded pH, temperature, specific conductivity,
dissolved oxygen (DO), and oxidation-reduction potential (ORP) (Table 2) 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. Field parameters were not collected from the supply wells.

Former Preslar's Exxon NCDOT WBS # 34348.3.5
Midland, Cabarrus County, NC May 18, 2016
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 volatile organic compounds (VOCs) by SM 6200B.
2.3 GROUNDWATER MONITORING RESULTS
Table 3 summarizes the results of the target compounds detected since the initial injection was
conducted and Table 4 summarizes the historical results of all detections. The applicable INC 2L
Standards are included for comparison. The laboratory analytical report for the March 2016 monitoring
event is provided in Appendix A.
Benzene was detected above its NC 2L Standard in samples MW-1, MW-4, and MW-13. Total xylenes,
ethylbenzene, and naphthalene were detected above their NC 2L Standards in sample MW-4 and
naphthalene was detected above the NC 2L Standard in sample MW-13. Other constituents detected,
but not exceeding the NC 2L Standards in samples MW-1, MW-4, and MW-13 include MTBE, IPE, and
toluene. The remaining wells contained no detectable concentrations of VOCs. Figure 4 presents an
interpretation of the lateral extent of benzene impacts identified in the shallow groundwater. No VOCs
were detected in water supply wells WSW-9 and WSW-11.
Total VOCs in MW-1 have shown a general downward trend in concentrations, based on the historical
data presented in Table 4, presumably a result of natural attenuation, enhanced with EAS°, in the aquifer.
Concentrations of VOCs in MW-4 and MW-13 have also decreased overtime. These relationships are
demonstrated on the charts in Appendix B.
The laboratory conducted sulfate analysis on all the groundwater samples collected. The results indicate
detections of sulfate in all the well samples ranging from 9.1 to 219 milligrams per liter (mg/L). None of
these results are above the NC 2L Standard of 250 mg/L for sulfate. Water supply well WSW-11, the well
of concern for sulfate, has shown a downward trend in the last two sampling events. Based on these
concentrations, the NCDEQ approved the second injection event at the site.
3.0 APRIL 2016 INJECTION EVENT
Groundwater remediation is ongoing at the site in accordance with the CAP Addendum and Permit
#W10300282. The approved remedy includes injections of EAS° sulfate solution into the groundwater
and monitoring the groundwater to evaluate the effectiveness. The objective of injecting sulfate into

Midland, Cabarrus County, NC May 18, 2016
groundwater is to stimulate indigenous sulfate -reducing bacteria to biodegrade the residual petroleum
constituents to concentrations below the NC 2L Standards.
From April 11 to 14, 2016, SIES conducted a second injection event by gravity -feeding EAS° into each
injection point directly from the 55-gallon drum in which it was shipped. Each drum was connected to the
well for injection by attaching a fitting to the drum bung and to the top of the injection well and connecting
the two with a hose. The drum was then tilted to accommodate draining the EAS° into the injection well.
No pressure was used to assist with the injection. SIES injected an average of 53 gallons of solution into
each of the 21 injection wells, equaling approximately 1,113 total gallons of product introduced into the
aquifer during this injection event. Based upon field observations, SIES calculated injection rates of
0.005 to 0.92 gallons per minute (gpm). Because the sulfate in EAS° is soluble, it is immediately
distributed into groundwater upon injection and no chase water was used. The initial distribution of
substrate at each well depended on the effective porosity of the aquifer at each location. Future spread
of sulfate between the injection points relies on groundwater flow velocity and direction. Appendix C
presents the Injection Event Record for the April 2016 injection.
In accordance with the injection permit, post -injection monitoring for this event will be conducted at a 6-
month interval, which will occur in October 2016. Field parameters and laboratory analyses will be
compared to previous results to evaluate the remediation effort.
In the event the groundwater analyses show rebound of the petroleum constituents, additional injection(s)
may be conducted. Groundwater sampling and analyses will be conducted at six-month intervals
following subsequent injections.
4.0 CONCLUSIONS
The petroleum source area for the Site is 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, xylenes, and naphthalene. Although other VOCs
were detected, their concentrations were below the NC 2L Standards. Based on the available data,
shallow groundwater appears to flow to the southeast.
Between April 11 and 14, 2016, approximately 1,113 gallons of aqueous EAS° sulfate/nutrient solution
was successfully introduced into the aquifer by gravity flow into 21 existing injection wells.

Midland, Cabarrus County, NC May 18, 2016
Based on the analytical results for the March 2016 sampling event, concentrations of benzene,
ethylbenzene, toluene, and naphthalene in samples from three of the monitoring wells continue to be
detected at concentrations above the remediation goals. These constituents continue to show a general
downward trend in the three injection performance monitoring wells. Therefore, continued monitoring is
recommended. The next sampling event will occur in October 2016. Following receipt of the sampling
results, SIES, NCDOT, and NCDEQ will evaluate the data to determine the need for additional injections.
