Re.: Entry Agreement Request to Sample Water Supply Well for Former Preslar's Exxon
Remediation
Midland, North Carolina
NCDOT Project No. R-6015B
Solutions-IES Project No. 2014.0009.NDOT
Dear Mr.:
The North Carolina Department of Transportation. (NCDOT) has retained Solutions-IES, Inc., (SIES) to
complete remedial action for the former Preslar's Exxon in Midland, North Carolina. In acquiring the right-
of-way for improvements on NC Highway 24/27, the NCDOT accepted responsibility for cleanup of a
petroleum release to groundwater from the former Preslar's location. Groundwater cleanup will consist of
injecting approved compounds into the groundwater to assist the degradation of the petroleum. Under
the- Underground Injection Control (UIC) permit (WI0300282) for the cleanup, the NCDOT is required to
collect groundwater samples from both monitoring wells and water supply wells in the vicinity of the
release. A receptor survey for the area identified an irrigation well located at SIES
understands that you are the property owner for that address.
The purpose of this letter, in addition to informing you of the cleanup, is to obtain your permission to
sample and analyze your well for petroleum constituents. Historically, samples from surrounding water
supply wells have shown no impact from the petroleum release and there is no indication that your well
has been affected. The sampling and analysis is for monitoring only, and will be conducted at no cost to
you with analytical results provided to you at your request.
If you agree to grant the NCDOT and SIES permission to collect groundwater samples from your well,
please execute the attached Agreement and return it to me via mail or email. Our next sampling is
scheduled for June 16, 2015. If you are not the property occupant, please provide a name and contact
information for your tenant so we can schedule a time to collect the sample.
Thank you for your time and attention to this matter. If you have questions or need additional information,
please contact me at 919-873-1060 ext 134, or by email at mbranson(cDsolutions-ies.com.
Yours truly,
Solutions-IES

Re.: Request to Revise Monitoring Plan for W10300282
Former Preslar's Exxon
Midland, North Carolina
NCDOT Project No. R-0615B
Solutions-IES Project No. 2014.0009.NDOT
Dear Mr. Rogers:
Solutions-IES, Inc., (SIES), on behalf of the North Carolina Department of Transportation (NCDOT), is
submitting this request to revise the groundwater monitoring plan for Injection Permit W10300282. As
indicated in Part VI (1) of the permit, a groundwater monitoring plan was developed and approved that
included 13 monitoring wells and four water supply wells. The water supply wells -anticipated for the
monitoring were WSW-9, WSW-10, WSW-11, and WSW-12 (see attached figure). Of these wells, only
WSW-9 was considered a potable well, and it was -720 feet from the source area. After receipt of the
injection permit, SIES conducted a baseline monitoring event and was unable to locate or access two of
the wells. In conducting research into the well locations, SIES discovered that with the exception of Ms.
Ida Thomas (WSW-11), no access agreements were in place to allow collection of groundwater samples
from the supply wells. Because the well sampling was part of a permitted activity, SIES located the
property owners through the Cabarrus County tax records and sent a letter (attached) on June 11, 2015,
to the following owners requesting access to collect groundwater samples.
• Mr. L.E. Dorton, Sr., 700 NC Hwy 24/27, Midland, North Carolina (WSW-9)
• Mr. George Plummer, 932 NC Hwy 24/27, Midland, North Carolina (WSW-12)
• Mr. David Watson, 12501 Jim Sossoman Road, Midland, North Carolina (WSW-10)
On June 22, 2015, SIES received a signed access agreement from Mr. David Watson. However, Mr.
Dorton and Mr. Plummer have not responded, although they have received the letter and request for
access agreement (attached receipts). Based on this non -response from the two owners, SIES has no
access to collect samples from wells WSW-9 and WSW-12. As a result, we request that these two wells
be removed from the monitoring plan or that the North Carolina Department of Environment and- Natural
Resources assist in gaining access.
Thank you for your attention to this matter. If you have any questions or need additional information,
please call me at [phone].
Yours truly,
Solutions-IES

Dear Mr. Branson,
Donald R. van der Vaart
Secretary
Per your written request in a letter dated July 29, 2015, to revise the monitoring plan for the above
referenced permit, the Water Quality Regional Operations Section (WQROS) of the Division of Water
Resources (DWR) is -omitting the sampling requirements for monitoring wells WSW-9 and WSW-12.
These wells were previously stipulated in Section 2.0 of the Baseline Groundwater Monitoring Plan of
this permit. The Mooresville Regional Office (MRO) is in agreement with this revision.
Both the MRO and Solutions IES have made attempts to gain access to the properties of Mr. L.E. Dorton,
Sr. whose address is 700 NC Hwy. 24/27, Midland, N.C., and Mr. George Plummer whose address is 932
NC Hwy. 24/27, Midland, N.C. Neither party has responded to requests to grant access for the purpose of
performing groundwater sampling for these properties adjacent to the subject site. Based upon your
several attempts to gain access, your request to omit these wells from the monitoring plan is reasonable
and is, therefore, approved.
Please consider this letter as an addendum to the current permit to remove WSW-9 and WSW-12 from the
groundwater monitoring plan. However, all previously stipulated requirements of the permit shall remain
in force. If you have any question or concerns related to this permit amendment, please contact Michael
Rogers with the Central Office at Micliael.Rogers@ncdenr.,gov (919-807-6406), or Edward Watson with
the MRO at [e-mail] (704-663-1699).

Baseline 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
June 3, 2015
Solutions-IES, Inc. (SIES) is in the initial stages of implementing 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 Baseline Groundwater Monitoring Report has been prepared for
the North Carolina Department of Transportation (NCDOT) Geotechnical Engineering Unit to document
the installation of injection wells at the Site and the pre -injection baseline groundwater conditions in
accordance with Underground Injection Control (UIC) Program Permit No. W10300282. It provides
information regarding injection well locations and construction, results of the groundwater sampling event
that took place in May 2015, and a summary of historical groundwater analyses leading up to the
upcoming remediation..
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: MWA , MW-3, MW-4, and MW-5. The
petroleum constituents exceeding the NC 2L Standards included benzene, ethylbenzene, toluene, total
xylenes, methyl-ten`-butylether (MTBE), isopropylether (I PE), naphthalene, C5-C8 aliphatics, C9-C18
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 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 North Carolina Department of
Environment and Natural Resources (NCDENR) 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 NCDENR 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
I EAS® is an aqueous solution of sulfate salts and nutrients available commercially from EOS Remediation, LLC in
Raleigh, NC.

was required within 30 days prior to injecting the substrate. The following sections outline the baseline
monitoring event and the injection well installation.
2.0 BASELINE GROUNDWATER MONITORING PLAN
The baseline monitoring plan, as approved in the injection permit, requires sampling at 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. In November 2014, SIES field personnel conducting a
sampling event for the water supply wells could not locate WSWA 0. The location of this well in previous
figures suggested that it was in the middle of a field. Further investigation into the location of this well
indicated that it is likely inside a locked well -house building and not in the field as believed. Because of
this location, previous sampling events may have unintentionally sampled well WSW-13 instead of WSW-
10. The figures in this sampling report have been revised to show the correct location of well WSW-10.
Well WSW-12 is an irrigation well that is used sporadically and controlled with a circuit breaker inside the
owner's house. For the May 2015 sampling event, the owners could not be contacted for access, and
WSW-12 was not sampled. For the post -injection monitoring, SIES will attempt to contact these well
owners so that access for sampling wells WSWA0 and WSWA2 can be granted.
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 referenced to a site datum with an
assumed elevation. Table 1 presents the May 2015 water level data with historical water level
measurements.
The groundwater elevation data for wells screened in the shallow aquifer were used to develop a shallow
potentiometric surface map for May 2015, shown as Figure 3. The groundwater contour map prepared
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
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 (Table 2), including pH,
temperature, specific conductivity, dissolved oxygen (DO), and oxidation-reduction potential (ORP) until

Baseline Groundwater Monitoring Report Solutions-IES Project No. 2014.0009.NDOT
Former Preslar's Exxon NCDOT WBS # 34348.3.5
Midland, Cabarrus County, NC June 3, 2015
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
(extended to include 1,2-DCA, naphthalene, IPE, and MTBE).
2.3 GROUNDWATER MONITORING RESULTS
Table 3 summarizes the results of the target compounds detected in May 2015 and Table 4 summarizes
the historical target compounds results. The applicable NC 2L Standards are included for comparison.
The laboratory analytical report for the May 4-5, 2015, monitoring event is provided in Appendix A.
As shown in Table 3, benzene was detected above its NC 2L Standard in wells MWA, MW-4, MW-5, and
MWA 3. Total xylenes and naphthalene were detected above their NC 2L Standards in wells MW-4 and
MWA 3. Other constituents detected, but not exceeding the NC 2L Standards in wells MWA, MW-4, and
MW-13 include ethylbenzene, MTBE, IPE, toluene, total xylenes, and naphthalene.- 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. The benzene detected in deep well MW-5 is
the first detection of that compound in the well since the initial sampling in 1998. The analyses for water
supply wells WSW-9 and WSWA 1 did not detect VOCs in either well sample.
Based on the historical data presented in Table 4, total VOCs in MWA have shown a general downward
trend in concentrations, presumably a result of natural attenuation in the aquifer. Concentrations of VOCs
in MW-4 and MWA3 have also shown natural.attenuation overtime. It should be noted that MW-4 and
MWA 3 were the performance monitoring wells closest to the pilot test injection of EAS® in June 2012
(SIES, 2013). The data suggest that there was a post -injection decrease in total BTEX in each of these
wells that was effective for 16 months in MWA 3 and 10 months in MW-4. However, the pilot test was
limited and after this period, each well has shown evidence of rebound of the total BTEX concentrations.
The laboratory conducted sulfate analysis on all the groundwater samples collected. The results indicate
detections of sulfate in all the well samples ranging from 3.3 to 64.4 milligrams per liter (mg/L). None of
these results are above the NC 2L Standard of 250 mg/L for sulfate. The sulfate concentrations were the
4

lowest in MW-4 (3.3 mg/L) and MW-13 (7.5 mg/L), which suggests that the pilot testing in the area
enhanced growth of sulfate -reducing bacteria which in turn reduced sulfate concentrations in the process
of metabolizing the contaminants, as desired.
3.0 GROUNDWATER REMEDIATION
As approved in the CAP Addendum, groundwater remediation will be conducted by injection of EAS®
sulfate solution into the groundwater and monitoring the groundwater to evaluate the effectiveness of the
remediation effort. As noted above, the objective of injecting sulfate into groundwater is to stimulate
indigenous sulfate -reducing bacteria to biodegrade the residual petroleum constituents. The goal of the
remediation is to reduce the petroleum constituents of concern present in the groundwater to
concentrations below the NC 2L Standards. Based on the successful pilot test, SIES designed an
injection program that included permanent injection wells suitable for multiple injections of substrate, if
needed. The well installations and the initial injection of EAS® are described in the following sections.
3.1 INJECTION WELL INSTALLATION
Under Injection Permit W10300282, the NCDOT was allowed to install up to 21 permanent injection wells
into the injection zone at the Site. On April 27, 2015, SIES and its subcontractor, American
Environmental Drilling, Inc. (AEDI), mobilized to the Site to install the wells. To facilitate the installation
and provide a margin of safety, the NCDOT provided traffic control. The injection zone included two
areas of the Site, the median of Hwy 24/27 and within the right-of-way of the highway's eastbound lane
(Figure 5). While working in the median, traffic was diverted to the two outside lanes and when on the
right-of-way, the southernmost lane was closed. During the installation activities, SIES determined that
the two wells used for the injection pilot test (PIW-1 and PMW-2) were in the appropriate location to be
used again. As a result, SIES installed only 19 wells, completing the installation activities on May 1,
2015.
Construction records for the wells are presented in Appendix B. Boreholes were located approximately
18 to 20 feet on center, arranged as shown in Figure 5. In June 2015, NCDOT will survey the location
and top of casing elevation for the monitoring wells and injection wells. The survey will also include
locations of the four water supply wells. This information will be incorporated into future figures to provide
a more accurate picture for monitoring reports. Because of the shallow bedrock, AEDI used air rotary
drilling methods to advance each borehole to 20 ft bgs. The injection wells were constructed of 1-inch
diameter PVC well material with 15 feet of 0.010-inch slotted screen from 5 to 20 ft bgs. The annular
space was filled with sand and topped with 4 ft of bentonite and cement bentonite mixture to the flush -
mounted manhole surface finish.

3.2 EAS®
Solutions-IES Project No. 2014.0009.NDOT
NCDOT WBS # 34348.3.5
June 3, 2015
The CAP Addendum prepared by SIES concluded that the most cost-effective groundwater remedy at the
site was sulfate -enhanced bioremediation. SIES purchased EAS® from EOS Remediation in Raleigh, NC.
EAS® is an electron acceptor solution composed of 30 to 37 percent sulfate salts, 1 to 1.5 percent
nutrients and water in solution. It does not require dilution. EAS® is an approved injectant by the North
Carolina UIC Program.
EAS® utilizes sulfate -enhanced technology for in situ remediation of petroleum contaminated groundwater
and stimulates biodegradation by providing a soluble, readily available electron acceptor. In the presence
of elevated sulfate, anaerobic groundwater bacteria use petroleum hydrocarbons for carbon and energy
while mineralizing the hydrocarbons to carbon dioxide and water. The following equation illustrates the
concept using toluene as the hydrocarbon:
C6H6 + 3.75SO42- + 7.5H+ —> 6CO2 + 3.75H2S + 3H2O
The reaction results in the complete degradation of the petroleum hydrocarbon.
3.3 INJECTION PROCEDURE
EAS® was gravity -fed 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
approximately 53 gallons of solution into each of the 21 injection wells, equaling approximately 1113 total
gallons of product introduced into the aquifer during this injection event. Based upon field observations,
SIES calculated injection rates of 0.15 to 1.8 gallons per minute (gpm). Because EAS® is an aqueous
solution, no chase water was used. The initial distribution of substrate from 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 May 2015 injection.
3.4 REMEDIATION EVALUATION
SIES will conduct sampling events at one month, three months, and six months after injection to evaluate
the effectiveness of the EAS®. Groundwater samples will be collected from the 13 existing site monitoring
wells (MW-1 through MW-13) and four water supply wells. As performed during prior and baseline
sampling events, wells will be low -flow purged until readings of pH, temperature, DO, ORP, turbidity and
conductivity stabilize. Groundwater samples will be analyzed for sulfate and 601/602 VOCs by SM

620013. 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 BTEX compounds, 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 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, xylenes, and naphthalene. Although
other VOCs have been detected, their concentrations are below the NC 2L Standards. Two of the water
supply wells in the monitoring plan could not be sampled during the May 2015 sampling event due to
access issues. Based on the available data, shallow groundwater appears to flow to the southeast.
Between May 18 and 20, 2015, approximately 1113 gallons of aqueous EAS® sulfate/nutrient solution
was successfully introduced into the aquifer by gravity flow into two existing and 19 new 1-inch diameter
injection wells. The wells are screened from 5 to 15 ft bgs and located in a grid pattern roughly covering
the interpreted footprint of the petroleum plume.
