1.0 INTRODUCTION
ATC Associates of North Carolina, P.C. (ATC), on behalf of Circle K Stores, Inc. (Circle K), is
submitting this monitoring report for the Circle K Store #2723301 facility located at 11495
Highway 15-501 and NC 211, Aberdeen, Moore County, North Carolina (Incident #22728).
Currently, the site is an active convenience store and retail fuel outlet. A site topographic map is
presented as Figure 1 and site map is presented as Figure 2. UST owner/operator and system
information is included in Table 1.

2.0 EXECUTIVE SUMMARY
The presence of petroleum-related impacts to soil, above Soil-to-Groundwater Maximum Soil
Contaminant Concentrations (STGW-MSCCs), were identified in four soil samples collected
during Limited Site Assessment (LSA) activities in proximity to the UST system. It should be
noted petroleum-related impacts to soil were not identified above the applicable Residential
MSCCs. Historical soil analytical data is on file at the NCDEQ Fayetteville Regional office in
previous reports.

Overall, the dissolved contaminant concentrations of concern include dissolved benzene and
MTBE in monitoring wells MW-1, MW-2, MW-5, MW-6, MW-7, MW-10, and MW-14. It
should be noted the identified dissolved benzene and MTBE concentrations are present above
established 2L Standards but below respective Gross Contaminant Levels (GCLs), with the
exception of dissolved benzene in monitoring well MW-1. As a consequence of the assessment
activities conducted at the facility, the horizontal and vertical extents of dissolved petroleum
hydrocarbon concentrations have been reasonably defined. Light non-aqueous phase liquid
(LNAPL) has not been associated with this release. Based on the most current groundwater
analytical data, it appears the dissolved target compound concentrations in monitoring wells
associated with this release have either decreased or remained relatively stable through time. In
2003, the dissolved contaminant mass at the site was estimated to cover an area approximately
84,700 square feet (ft2) resulting in:
• a calculated dissolved benzene mass of 199.2219 kilograms (kg);
• a calculated soil source zone benzene mass of 0 kg; and,
• a calculated smear source mass of 0 kg.

Monitoring Report January 3, 2023
NCDEQ Incident No. 22728

Page 2
These calculations resulted in a total mass baseline/milestone benzene concentration of 199.2219
kg.
Based on the most recent groundwater analytical data (November 2022), the dissolved
contaminant mass at the site was estimated to cover an area approximately 33,000 ft2 resulting in
a calculated dissolved benzene mass of 26.2417 kg. To date, the dissolved benzene mass has
decreased at the site by approximately 86.828%. A geologic transect and geologic cross-sections
with 2000 analytical data are included in Appendix A.

ATC recommends the installation of biosocks in select monitoring wells to assist with natural
attenuation and to perform annual groundwater sampling of select monitoring wells and collecting a
surface water sample from the tributary to Aberdeen Creek. The next sampling event would be
performed during November 2023.

3.0 SITE HISTORY
The Pantry (Circle K) took over store operations from Wicker Oil Company, Inc. in the fall of 1999.
A release was discovered during a Phase II Environmental Site Assessment (ESA) conducted for
the property transaction. As a result, a Phase I Limited Site Assessment (LSA) was conducted at the
site during late 1999. Due to an insufficient water column in monitoring well MW-1, a second well
(MW-2) was installed at the site. Dissolved target compound concentrations were detected in the
groundwater sample collected from monitoring well MW-2 above ten times the 2L Standards.

In response, a Phase II LSA was prepared which included the installation of monitoring wells MW-
3 through MW-6. A Phase II LSA was submitted to the North Carolina Department of
Environmental Quality (NCDEQ) on February 14, 2000. The site was given a priority ranking of
intermediate risk with residential land use.

Based on the findings presented in the Phase II LSA Report, a Notice of Regulatory Requirements
(NORR) was issued for the preparation of a Comprehensive Site Assessment (CSA). The CSA
included the installation of nine monitoring wells (MW-7 through MW-15). A CSA Report was
submitted to the NCDEQ on May 28, 2002.

The site and surrounding area are classified by Moore County as mainly commercial and
industrial uses. The site is zoned commercial by Moore County. Adjacent property owner
information is included as Table 2.
During previous assessment activities, water supply wells were not identified within 1,500 feet
of the subject facility. Public water supplies in the area are provided by the City of Aberdeen.
The nearest surface water body is an unnamed tributary to Aberdeen Creek located
approximately 157 feet east of the source area.

This report documents the results of the recent groundwater sampling event.

4.0 GROUNDWATER MONITORING
4.1 Geology and Hydrogeology
The subject facility is located within the Cretaceous Middendorf Formation of the Coastal Plain
Physiographic Province. According to the Geologic Map of North Carolina (Brown, et al, 1985),
the bedrock is characterized by grey to pale grey with an orange cast, mottled sand, sandstone,
and mudstone. Clay balls and iron-cemented concretions are common. Beds are laterally
discontinuous and cross bedding is common.

Groundwater movement in the upper portion of the surficial aquifer appears to flow in a
northwestern direction across the site. Based on available groundwater data, it appears there is a
slight vertical head difference between the shallow and deep monitoring well, which suggest that
a vertical exchange of groundwater may occur between the upper and lower portions of the
surficial aquifer.

As part of the CSA, slug tests were conducted using monitoring wells MW-6, MW-8, and
MW-9. Based on the slug test results, the average hydraulic conductivity at the site was
calculated to range between 10.49 feet per day to 21.75 feet per day. The average groundwater
flow velocity was calculated to range between 0.00147 feet per year to 0.00304 feet per year.

4.2 Groundwater Elevations
On November 21, 2022, ATC collected static water level measurements from monitoring wells
MW-1, MW-2, MW-5, MW-6, MW-7, MW-9, MW-10, and MW-14. Depths to water

measurements were collected using an electronic oil/water interface probe. The groundwater
depths were converted to relative elevations using an assumed datum of 100 feet relative to an
arbitrary on-site benchmark. Monitoring well construction details are included in Table 3. Current
and historical groundwater elevation data are included in Table 4. A groundwater elevation contour
map based on the November 2022 static water level data is included as Figure 3. Based on the
recent groundwater level measurements, groundwater flow appears to be toward the north.
Historically, groundwater flow appeared to be toward the northwest. Historical groundwater flow
maps are provided in Appendix B.

4.3 Groundwater Analytical Results
Monitoring Wells
On November 21, 2022, groundwater samples were collected from monitoring wells MW-1,
MW-2, MW-5, MW-6, MW-7, MW-9, MW-10, and MW-14. Groundwater samples were
collected into laboratory-approved containers, packed in ice and delivered under chain-of-
custody to SGS North America, Inc. (SGS) in Scott, Louisiana, for analyses. Groundwater
samples were analyzed for volatile organic compounds (VOCs) via EPA Method 6200B to
include ethanol and oxygenates. A summary of the recent groundwater analytical data is
presented in Table 5 and a historical summary of groundwater analytical data is presented in
Table 6. Select natural attenuation measurements are provided in Table 7.

The laboratory analytical results from the November 2022 sampling event indicated several
dissolved target compound concentrations exceeded their established 2L Standards in the
groundwater samples collected from monitoring wells MW-1, MW-2, MW-5, MW-6, MW-7,
MW-9, MW-10, and MW-14. It should be noted some dissolved target compound
concentrations exceeded the established 2B x 10 Standards in the groundwater samples collected
from monitoring wells MW-1, MW-2, MW-5, and MW-10. Also, the dissolved benzene
concentration detected in the groundwater sample from monitoring well MW-1 was noted to be
above the established GCL.

A dissolved benzene isoconcentration contour map is included as Figure 4. A dissolved MTBE
isoconcentration contour map is included as Figure 5. Other dissolved contaminants of concern are
included as Figure 6. It appears dissolved target compound concentrations in the groundwater

samples from the monitoring wells being sampled are either decreasing or remaining relatively
stable through time.

Groundwater concentration trend plots for dissolved benzene and MTBE concentrations in
monitoring wells MW-1 and MW-2 versus depth to water are included as Figures 7 and 8,
respectively. A copy of the laboratory analytical report is included as Appendix C.

Overall, the dissolved contaminant concentrations of concern include dissolved benzene and
MTBE in monitoring wells MW-1, MW-2, MW-5, MW-6, MW-7, MW-10, and MW-14. It
should be noted the identified dissolved benzene and MTBE concentrations are present above
established 2L Standards but below respective Gross Contaminant Levels (GCLs), with the
exception of dissolved benzene in monitoring well MW-1. As a consequence of the assessment
activities conducted at the facility, the horizontal and vertical extents of dissolved petroleum
hydrocarbon concentrations have been reasonably defined. LNAPL has not been associated with
this release. Based on the most current groundwater analytical data, it appears the dissolved
target compound concentrations in monitoring wells associated with this release have either
decreased or remained relatively stable through time. In 2003, the dissolved contaminant mass at
the site was estimated to cover an area approximately 84,700 square feet (ft2) resulting in:
• a calculated dissolved benzene mass of 199.2219 kilograms (kg);
• a calculated soil source zone benzene mass of 0 kg; and,
• a calculated smear source mass of 0 kg.
These calculations resulted in a total mass baseline/milestone benzene concentration of 199.2219
kg.

Based on the most recent groundwater analytical data (November 2022), the dissolved
contaminant mass at the site was estimated to cover an area approximately 33,000 ft2 resulting in
a calculated dissolved benzene mass of 26.2417 kg. To date, the dissolved benzene mass has
decreased at the site by approximately 86.828%. The contaminant mass calculations are
provided in Table 8 and contaminant mass removal is provided in Table 9. Contaminant mass
versus time is provided in Appendix D.

Surface Water Sampling
On November 21, 2022, a surface water sample was collected from an unnamed tributary to
Aberdeen Creek. The location of the surface water sample is noted on Figure 2 (labelled SW-1).
The surface water sample was collected by direct dip. The surface water sample was collected
directly into laboratory-approved containers, packed in ice and delivered under chain-of-custody
to SGS North America, Inc. (SGS) in Scott, Louisiana, for analyses. Groundwater samples were
analyzed for volatile organic compounds (VOCs) via EPA Method 6200B to include ethanol and
oxygenates.

Laboratory analytical results of the surface water sample collected from the unnamed tributary to
Aberdeen Creek did not detect dissolved target compound concentrations above laboratory method
detection limits (MDLs). A summary of the recent groundwater analytical data is presented in
Table 5. A copy of the laboratory analytical report is included as Appendix C.

6.0 MONITORING PLAN AND SCHEDULE
ATC recommends the installation of biosocks in select monitoring wells to assist with natural
attenuation and to perform annual groundwater sampling of select monitoring wells and collecting a
surface water sample from the unnamed tributary to Aberdeen Creek. The next sampling event
would be performed during November 2023.

7.0 CONCLUSIONS
ATC has performed a groundwater sampling event at the Circle K Store #2723301 located in
Aberdeen, North Carolina. Based on field activities, observations, and groundwater analytical
results, ATC concludes the following:
• Depth to groundwater measurements in the shallow aquifer ranged from 1.20 feet to 25.85
feet below ground surface MW-14 and MW-7, respectively. Based on information obtained
during the November 2022 sampling event, groundwater appears to flow across the site in a
northerly direction;
• An unnamed tributary to Aberdeen Creek is located approximately 157 feet east of the source
area;
• The source area is not located within an approved wellhead protection area;
• Public water is supplied to the site and surrounding area by the City of Aberdeen;
