2.0 EXECUTIVE SUMMARY
ATC Associates of North Carolina, P.C. (ATC) has completed a Groundwater Monitoring Report
for the Jeff’s Grocery site. This report documents groundwater sampling activities conducted at the
site in November 2019. The activities were performed based on an October 17, 2019 Task
Authorization (TA-04) by the Trust Fund Branch of the Underground Storage Tank (UST) Section,
Division of Waste Management, North Carolina Department of Environmental Quality (NCDEQ).
The work is being performed as part of State Lead Contract #N17004 between NCDEQ and ATC.
The former Jeff’s Grocery site is located at 2996 NC Highway 268 in Pinnacle, Stokes County,
North Carolina. The site is developed with one single-story brick building and is currently used
as a convenience store. Three monitoring wells are located at the site. Nine potable water supply
wells are located within 1,000 feet of the site. Municipal water is not available to the site or
vicinity.
On November 19, 2019, ATC personnel mobilized to the site to supervise the installation of two (2)
monitoring wells (MW-2 and MW-3). On November 20, 2019, ATC personnel mobilized to the
site to collect a groundwater sample from MW-1, MW-2, MW-3, and water supply wells WSW-1,
WSW-3, WSW-4, and WSW-5. Laboratory results indicate methyl tert-butyl ether (MTBE) above
the North Carolina Groundwater Quality Standards (2L Standards) but below the Gross
Contaminant Levels (GCLs) in MW-1. None of the samples collected from the water supply
wells contained concentrations exceeding the laboratory detection limits. Based on the sampling
results collected to date, the plume is limited to the area around MW-1.
The site is not a candidate for closure due to the presence of potable water supply wells within
1,000 feet of the site, most notably WSW-1 located on the source property. ATC recommends
groundwater and water supply well sampling on an annual basis.

3.0 SITE DESCRIPTION
3.1 Site Characterization
The Jeff’s Grocery site formerly operated as a convenience store and petroleum retail facility.
Currently, the site is used as Cornerstone Market, a convenience store. The former UST system
consisted of two 3,000-gallon gasoline USTs located at the southwestern corner of the onsite
building. The USTs were in operation from 1984 until March 2008 when they were removed from
the site. Three (3) monitoring wells (MW-1 through MW-3) are associated with the site.
Properties surrounding the site are used for residential and agricultural purposes or are undeveloped.
A site topographic map is included as Figure 1. Nine water supply wells are located within 1,000
feet of the site. Water supply well ownership information is included in Table 1 and a site map
depicting monitoring well locations and other pertinent site features is included as Figure 2. A
potential receptor map is included as Figure 3.
3.2 Site Background
In August 2007, ECS Carolina, LLP, submitted a Report of Environmental Services documenting
soil and groundwater assessment activities performed at the site at the request of property owner,
Mr. Chad Lynch. During the assessment, soil borings GP-1 through GP-10 were advanced around
the UST system and a groundwater sample was collected directly downgradient of the USTs. Soil
samples collected from boring GP-7 through GP-10 contained levels of total petroleum
hydrocarbons (TPH) gasoline range organics (GRO) and/or diesel range organics (DRO) above the
NCDEQ Action Level. The groundwater sample did not contain petroleum compounds above
laboratory detection limit.
On March 26, 2008, Geological & Environmental Services submitted a UST Closure Report for the
site. During the closure, two 3,000-gallon gasoline USTs were removed from the site. Soil samples
collected from beneath the USTs and dispenser did not contain petroleum hydrocarbons above the
respective standards; however, the soil directly beneath the product lines indicated impact. Over

excavation was performed in the vicinity of the product lines. Following over excavation activities,
samples were collected from beneath the product lines at approximately 8 feet below ground surface
(bgs) and contained soil impacts above Soil-to-Groundwater Maximum Soil Contaminant
Concentrations (MSCCs). Approximately 50 tons of soil was removed from the site during the
UST Closure.
On April 29, 2011, Terraquest Environmental Consultants, P.C. submitted a Receptor Survey and
Water Supply Well Sampling Report. Based on the results of the receptor survey, nine active water
supply wells are located within 1,000 feet of the site. Water supply wells WSW-1 through WSW-6
were sampled in March and April 2011. Lead was detected in water supply wells WSW-5 and
WSW-6 above the 2L Standard. Based on a 2-step, first draw method of sampling, it was
determined the source of lead for WSW-5 was from the home supply line while the source of
lead for WSW-6 was the groundwater. No other compounds were detected in the samples.
On June 18, 2015, ATC submitted a Letter Report documenting a water supply well sampling event.
During the event, samples were collected from water supply wells WSW-1, WSW-3, WSW-5, and
WSW-6. Chloromethane was detected in water supply well WSW-6 at a concentration of 0.36
micrograms per liter (g/L) which is below the laboratory reporting limit as well as the 2L
Standard. No other compounds were detected is the water supply well samples. Water supply
well information is included in Table 1. ATC recommended completion of a soil assessment
around historical soil borings GP-7, GP-8, GP-9, and GP-10 to determine current soil impacts at
the site.
On October 8, 2015, ATC submitted a Soil Assessment Report documenting the collection of
four soil samples (SB-1 through SB-4). The soil borings were placed in the vicinity of former
soil borings GP-7 through GP-10 to determine current soil concentrations at the site. Based on
the laboratory results, it appears compounds are attenuating in the soil. ATC recommended
installing one monitoring well in the vicinity of the former product lines to determine impacts to
groundwater.

On June 3, 2016, ATC submitted a Groundwater Monitoring Report documenting the installation
and sampling of monitoring well MW-1. The sample collected from MW-1 indicated MTBE
above the 2L Standard. ATC recommended installing two additional monitoring wells to
determine groundwater flow direction, placement of O-SOX in monitoring well MW-1, and
performing a water supply well sampling event.
On August 27, 2016, ATC submitted a Water Supply Well Sampling Letter Report documenting
the sampling of water supply wells WSW-1, WSW-3, WSW-4, and WSW-5. No compounds
were detected. The report also documented the placement of O-SOX in monitoring well MW-1.
ATC recommended sampling monitoring well MW-1 in January 2017.
On May 11, 2017, ATC submitted a Groundwater Sampling Letter Report documenting the
sampling of monitoring well MW-1 and water supply well WSW-1. Monitoring well MW-1
indicated MTBE and naphthalene above the 2L Standards. No compounds were detected in
water supply well WSW-1. ATC recommended placement of O-SOX in monitoring well MW-1
with sampling of MW-1 three months later.
On May 14, 2018, ATC submitted a Groundwater Sampling Letter Report documenting the
sampling of water supply wells WSW-1, WSW-3, WSW-4, and WSW-5. Monitoring well MW-
1 indicated MTBE above the 2L Standard. No compounds were detected in water supply wells
WSW-1, WSW-3, WSW-4, or WSW-5. ATC recommended placement of O-SOX in monitoring
well MW-1 with sampling of MW-1 three months later.
On June 25, 2019, ATC submitted a Groundwater Sampling Letter Report documenting the
sampling of water supply wells WSW-1, WSW-3, WSW-4, and WSW-5. Monitoring well MW-
1 indicated MTBE above the 2L Standard. No compounds were detected in the water supply
wells. ATC recommended installing and sampling two (2) additional monitoring wells at the site
to delineate groundwater impact and to determine groundwater flow direction.

This report documents the installation of monitoring wells MW-2 and MW-3 on November 19,
2019 and the subsequent, groundwater and water supply well sampling event on November 20,
2019.
4.0 MONITORING WELL INSTALLATION
As authorized in TA-04, ATC supervised the installation of monitoring wells MW-2 and MW-3 on
November 19, 2019. Monitoring well MW-2 is located in the paved area off the southwestern
corner of the site building. Monitoring well MW-3 is located in the paved/gravel area in the
east/southeastern portion of the site. The purpose of these wells was to determine the extent of
groundwater impact and to determine the direction of groundwater flow. Geologic Exploration,
Inc. installed the monitoring wells to 35 feet below ground surface (bgs) with 15 feet of 0.010-
inch slotted screen via hand auger and air drilling techniques. Lithology encountered during the
monitoring well installation consisted mainly of silt. Field notes documenting well installation
activities are included as Appendix A. Soil boring logs and well construction records are
included as Appendix B. A site map identifying the newly installed monitoring well is presented
as Figure 2.
5.0 GROUNDWATER ASSESSMENT ACTIVITIES
5.1 Groundwater Levels
On November 19, 2019, ATC surveyed monitoring wells MW-1, MW-2, and MW-3 using MW-1
as a benchmark. On November 20, 2019, groundwater level measurements and samples were
collected from monitoring wells MW-1, MW-2, and MW-3. Monitoring well construction details
and groundwater elevation data are summarized in Table 2. Light non-aqueous phase liquid
(LNAPL) was not observed in any of the monitoring wells that were gauged. Depth to groundwater
measurements ranged from 26.73 feet bgs in MW-2 to 32.02 feet bgs in MW-3. A groundwater
elevation contour map generated using the November 2019 groundwater elevation data is included
as Figure 4. This figure indicates that the direction of groundwater flow at the site is to the east.
Field notes from the sampling event are included in Appendix A.

5.2 Groundwater Quality
On November 20, 2019, groundwater samples were collected from monitoring wells MW-1, MW-2,
and MW-3. Samples were collected in laboratory-approved containers, packed in ice and
delivered under chain-of-custody protocol to SGS North America Inc., in Scott, Louisiana for
analyses. Groundwater samples were analyzed for volatile organic compounds (VOCs) by
Environmental Protection Agency (EPA) Method 6200B.
The analytical results were compared to the 2L Standards and GCLs. MTBE was detected in
MW-1 at 67.4 µg/l, exceeding the 2L Standard, but below the GCL. A comparison of the current
analytical results (November 20, 2019) to the results of the previous sampling event (May 24,
2019) indicates a slight decrease in MTBE concentrations in MW-1. Monitoring well analytical
results are included in Table 3. Natural attenuation parameters are summarized in Table 4. A
MTBE isoconcentration contour map is included as Figure 5. The laboratory analytical report
and chain-of-custody forms are included in Appendix C.
As part of ATC’s quality assurance and quality control (QA and QC) measures, a data review of
the laboratory report was conducted. During the review, it was concluded that samples were
received by the laboratory in acceptable condition and properly preserved. Samples were
analyzed within the correct holding times, and the chain of custody was properly completed by
all parties. The laboratory QC report shows an internal blank was analyzed for each method that
was used for the original samples. The laboratory fortified blank (LFB) and laboratory control
sample (LCS) data results were also provided for each analytical method. Refer to the laboratory
report in Appendix C for details regarding QA results for the laboratory samples and any noted
exceptions. Overall, ATC concludes that the laboratory results are usable and any exceptions do
not significantly impact the conclusions presented in this report.

5.3 Water Supply Wells
Nine active water supply wells are located within 1,000 feet of the site. Municipal water is not
available in the vicinity of the site. Table 1 presents the water supply well ownership
information and Figure 3 depicts the water supply well locations.
ATC collected groundwater samples from WSW-1, WSW-3, WSW-4, and WSW-5 during the
November 20, 2019 sampling event. The owner of WSW-2 indicated there is no water supply
well at this location; however, he does plan on installing a water supply well in the future. The
owner of WSW-6 refused to grant permission to collect a sample. The samples were collected in
laboratory-approved containers, packed in ice and delivered under chain-of-custody protocol to
SGS for analyses. The samples were analyzed for VOCs by EPA Method 6200B. None of the
samples contained concentrations exceeding the laboratory detection limits. The water supply
well analytical results are summarized in Table 5. The QA and QC measures and conditions
applicable to the monitoring well sampling also apply to the water supply well sampling. The
laboratory analytical report and chain-of-custody forms are included in Appendix C.
6.0 CONCLUSIONS AND RECOMMENDATIONS
On behalf of the Trust Fund Branch of the UST Section, ATC completed a Groundwater
Monitoring Report documenting the November 2019 assessment and groundwater sampling
activities at the Jeff’s Grocery property located at 2996 NC Highway 268 in Pinnacle, Stokes
County, North Carolina. Groundwater samples were collected from monitoring wells MW-1,
MW-2, and MW-3 and water supply wells WSW-1, WSW-3, WSW-4, and WSW-5.
Results from the monitoring event indicated MTBE above 2L Standard but, below GCL in
monitoring well MW-1. None of the samples collected from the water supply wells contained
concentrations exceeding the laboratory detection limits.
