GROUNDWATER MONITORING REPORT
FORMER ASHBY’S GROCERY – NC DEQ Incident #13501
3388 NC HIGHWAY 119 N., LEASBURG, NC

1.0 EXECUTIVE SUMMARY

As requested by Sparks Oil Company (Sparks), Pyramid Environmental & Engineering, P.C.
(Pyramid) has completed the Groundwater Monitoring Report for the James Ashby’s ’76
(Ashby’s Grocery) site. The Ashby’s Grocery site is located at 3388 NC Highway 119 N. in
Leasburg, Caswell County, North Carolina. Based on the area reconnaissance and interviews, a
total of ten (10) water supply wells were identified within 1,500 feet of the source area.
Currently, no municipal water supply (city or county) is available for the subject site or
surrounding properties. The current risk classification for the site is High Risk H715D.

Initial soil assessment at the site was completed as part of the CSA, prepared by Salem
Environmental in 1996, and included a number of soil borings and underground storage tank
(UST) samples. The Ashby’s Grocery site had three UST systems, all of which used dispensers at
the same pump island. Soil samples collected during UST closure activities in 1994 and
Geoprobe soil borings underneath the gasoline tanks of UST System #2 did not show detections
of TPH over the 10 parts per million (ppm) action level for EPA Method 5030. Soil samples
collected during the closure of UST System #1 showed levels of TPH in the gasoline range that
exceeded the action levels for EPA Method 5030 (>10 ppm). The tanks for UST System #1 were
formerly located between the store and the pump island. The highest TPH levels were detected
underneath the USTs and on the north sidewall of the excavation and ranged from 243 - 430
ppm. The results of the assessment showed the area surrounding the pump island and former
550-gallon USTs contained petroleum contamination. The soil cleanup goals established by the
NCDEQ for the Ashby’s Grocery incident are the Soil-to-Groundwater (STGW) Maximum Soil
Contaminant Concentration Levels (MSCCs).

Additional soil assessment was conducted on July 13, 1998, by ENSCI. Samples from two
Geoprobe borings (GP-1 & GP-2) were collected on the north and south sides of the former UST
System #1 excavation area. The results of the analyses indicated no detections in the sample
collected from GP-1, but the GP-2 sample indicated levels of VPH (C9-C10 Aromatics) and
naphthalene which exceeded the maximum allowable STGW concentrations.

In June 2011, Pyramid installed 13 soil borings (SB-1 through SB-13) to further assess soil
conditions at the site. Laboratory results for the June 2, 2011 soil sampling event identified the
presence of targeted compounds at the concentrations above the STGW MSCCs in soil borings
SB-3 and SB-4 installed in the area of the former pump island, as well as in SB-6 installed 10 feet
east of the former pump island. Concentrations of some targeted compounds were also above
the Residential MSCCs in SB-4. Soil assessment activities completed on June 2, 2011 identified

Sparks Oil Co.: Ashby’s Grocery (Incident # 13501) - Groundwater Monitoring Report 2
Pyramid Project # 2021-325 01/09/2023

residual contaminated soil in the area of the former pump island located between former UST
systems #1 and #3.

From January 16 – 25, 2012, Pyramid supervised the excavation of 397.80 tons of petroleum
contaminated soils at the site. The petroleum contaminated soils were excavated from the area
of the earliest UST systems, and included the former product piping and dispenser areas. Four
(4) composite disposal samples were collected from the excavated soils as the work progressed.
The laboratory results for three of the soil samples showed detections above the DEQ initial
action limits of 10 mg/kg to GRO and DRO.

Five (5) post-excavation soil samples were collected from the limits of the soil excavation .The
laboratory results of the risk-based analyses for three of the soil samples did not detect any of
the targeted compounds over laboratory detection limits. The laboratory results for one soil
sample detected VOC compounds above laboratory reporting limits, but below Soil-to-
Groundwater (STGW) and residential Maximum Soil Contaminant Concentration (MSCC) levels.
The laboratory results for soil sample BSS detected VOC compounds and VPH fractions above
STGW and residential MSCC levels.

The original CAP was designed to provide long-term soil and groundwater cleanup in the source
area using SVE and Pump & Treat technologies. The CAP was approved in 2002, but the
remediation system was not implemented because of financial changes in the NCDEQ UST Trust
Fund. From 2001 through 2006, Sparks/Pyramid performed sampling of the area supply wells
and maintained contact with the DEQ concerning concentration trends in the area.

In 2004, Pyramid/Sparks investigated whether the surrounding well users would agree to
connect to a community well system. The private water supply well users within 1,000 feet of
the site were interviewed and agreed with the concept. Pyramid prepared agreements that
were sent to all of the well owners within 1,000 feet of the site. The entire community was in
agreement in 2004 and all owners within 1,000 feet signed agreements to connect to a
community well. A number of operational set-backs prevented the community well from being
constructed.

Since the soil assessment and soil excavation in 2011 - 2012, Pyramid has performed six MMPE
events and continues to conduct groundwater monitoring events at the site. The last MMPE
event was conducted from April 11 - April 15, 2016, and a total of 4,585 gallons of
contaminated groundwater were recovered from MW-1, MW-13, and MW-17. These MMPE
events were instrumental in reducing the petroleum hydrocarbon mass and lowering the high
concentrations of petroleum contaminants below the GCLs within the surficial aquifer at the
site.

The environmental assessment activities completed to date have not identified the presence of
free-phase petroleum product at the site.

Sparks Oil Co.: Ashby’s Grocery (Incident # 13501) - Groundwater Monitoring Report 3
Pyramid Project # 2021-325 01/09/2023

The most recent groundwater monitoring activities for the Ashby’s Grocery site were
completed in February 2022. In February 2022, the concentrations of benzene, toluene,
ethylbenzene, and xylenes (BTEX) ranged from below detection limits in perimeter monitoring
wells (MW-4, MW-8, and MW-12) to 3,181 µg/L in MW-1. The detected BTEX concentrations in
MW-1, MW-2, MW-13, MW-14, and MW-15 indicate that there is still significant petroleum
contamination present in groundwater at the site.

The groundwater analytical results of the February 2022 sampling event detected
concentrations of MTBE at a level exceeding the 2L Groundwater Standard only in monitoring
well MW-5D. The deep well (MW-5D) has shown concentrations of MTBE above the 2L
Groundwater Standards since 1997. TAA and TBA, which are degradation byproducts of MTBE,
were detected at concentrations above the 2L Groundwater Standards in monitoring wells MW-
1, MW-2, MW-5D, and MW-14.

Petroleum compounds including naphthalene, 1,2,4-trimethylbenzene, isopropylbenzene, 1,2-
dichloroethane, and n-propylbenzene, were detected above 2L Standards in several monitoring
wells in February 2022. The concentrations of these compounds have generally remained the
same since January 2019.

Based on the lingering groundwater contaminant concentrations above the 2L Groundwater
Standards, which have generally stay the same since January 2019, and the presence of private
water supply wells in the area, the site remains high risk. The remediation goals are to reduce
dissolved groundwater contamination below the NCAC 2L Groundwater Standards in the source
area and the weathered rock and bedrock zones of the aquifer. Pyramid recommends the
following:

• Continued annual groundwater monitoring activities.

• The application of an in-situ chemical oxidant (e.g. PersulfOx by Regenesis) at the site to
address the persistent groundwater contaminant concentrations above the 2L
Groundwater Standards. Prior to the full-scale implementation of the oxidant at the site,
a pilot study should be conducted to determine the oxidant effectiveness and radius of
influence.

Three UST systems have been removed from the subject property. UST System #2 consisted of
three gasoline USTs (tanks #1, #2, and #3) owned by Sparks Oil, two 2,000-gallon tanks and one
8,000-gallon tank. One of the 2,000-gallon tanks was installed in 1982, and the other two tanks
were installed in approximately 1983. These three USTs were located in front of the former
barbecue restaurant building, and were removed on June 28, 1994, without incident. The
former locations of the tanks are shown on Figure 2A. The UST removal and closure activities
were coordinated and supervised by Certifoam Services\Salem Environmental in Winston-
Salem, North Carolina.

Pyramid Project # 2021-325 01/09/2023

The second (older) system (UST System #1) consisted of three USTs (tanks #4, #5, and #6), two
550-gallon gasoline USTs, which had reportedly been out of service since 1980, and one 1,000-
gallon gasoline UST that was reportedly used until 1985, then converted to a kerosene UST.
These USTs were acquired by Sparks Oil when they purchased Eggleston Oil Company. The
installation dates of these were in 1964 and 1976. The USTs were located in front of the Ashby’s
Store, underneath the pump island canopy (see Figure 2A), and were removed on June 29,
1994. The results of the closure sampling and laboratory analysis indicated a release from the
UST system. The UST removal and closure activities were coordinated and supervised by
Certifoam Services\Salem Environmental in Winston-Salem, North Carolina.

In early 1994, three 2,000-gallon gasoline USTs were installed on the west side of the pump
island canopy by a new fuel supplier (UST System #3). The former Ashby’s Store building was
burned down in 2007 and demolished and removed from the site in 2009. The last UST system
present at the site (three 2,000-gallon gasoline tanks owned by James Ashby) was removed in
December 2009. The laboratory results for all UST closure soil samples collected underneath the
three USTs were below regulatory action limits.

3.2 Risk Characterization

The residents of the area are served by individual water supply wells, which are the primary
source of drinking water. A few residents rely on bottled water due to water quality issues
including excess calcium and iron. Due to the rural nature of the site, it is unlikely that
municipal water will ever be available to this area. The site is in a rural area where all properties
rely on water supply wells as the source of potable water. The site is classified as “high-risk”
since active water supply wells are located within 1,500 feet of the source area. The results of
the most recent receptor survey (2010) showed ten (10) water supply wells within 1,500 feet of
the source area. The current risk classification for the site is High Risk H715D.

3.2.1 Water Supply Wells
The names and address of the adjacent property owners are listed in Table 2 and the water
supply well locations are shown on Figure 3. A total of ten (10) water supply wells were
identified within 1,500 feet of the source area in 2010. Five (5) active water supply wells were
observed within 500 feet of the source area.

Supply wells Lonnie Bowes (3425) and Lawrence W. Bowes (3190) have been impacted by
petroleum-related hydrocarbons. The locations of the supply wells are shown in Figure 3.
Sparks Oil Company has been providing bottled water to the Lonnie Bowes residence since
March 2000 due to the 1,2-dichloroethane detection above the 2L Groundwater Standard. 1,2-
dichloroethane has not been detected in the Lonnie Bowes well since the May 2015 sampling
event.

Sparks Oil Co.: Ashby’s Grocery (Incident # 13501) - Groundwater Monitoring Report 7
Pyramid Project # 2021-325 01/09/2023

The Lawrence W. Bowes (3190) supply well has been regularly showing low concentrations of
MTBE. The well has never shown any detection of MTBE at a concentration higher than 14 µg/L
identified in 2002 and 2005. Since 2005 concentrations of MTBE have decreased over time.
MTBE concentrations in the Lawrence W. Bowes supply well have remained bello 2 µg/L since
2016.

According to Pyramid’s records, only one health risk evaluation (HRE) was conducted by an
environmental toxicologist for the Lonnie Bowes (3425) supply well when low concentrations of
chloroform (12.7 µg/L) and naphthalene (2.3 µg/L) were detected in the well in January 2012.
No restriction on the use of the supply well water was recommended in the HRE report dated
March 13, 2012.

3.2.2 Public Water Supplies
The subject site and all surrounding properties are connected to water supply wells. No
municipal water supply (city or county) is available to the subject site or surrounding properties
at this time.

From 2004 until 2011, Sparks/Pyramid worked to propose, approve, and build a community
well to serve the area. Although the local landowners agreed to the concept, for operational
reasons, the project was not supported and failed.

3.2.3 Surface Water
In general, both surface and shallow groundwater flow directions are controlled by topographic
contours of land forms in the Piedmont, with flow occurring perpendicular to the contours from
high to low elevations. However, in fractured rocks, actual groundwater flow directions cannot
be easily determined. In fact, determining specific flow paths is impossible where the
groundwater flows through a complex network of bedrock fractures.

Based on review of the Ridgeville USGS map and area reconnaissance, the closest surface water
is a tributary to Reedy Fork Creek which is located approximately 900 feet southwest of the
contaminant source area. A tributary to Hyco Creek is also located approximately 1,400 feet
southeast of the contaminant source area. A freshwater pond is located 910 feet east of the
site. These surface waters are not considered receptors for groundwater contamination due to
their distances from the site. The location of the site relative to the these tributaries is shown in
Figure 1.

3.2.4 Wellhead Protection Areas
There are no designated wellhead protection areas within a 1,500-foot radius of the site.

3.2.5 Deep Aquifers in the Coastal Plain Physiographic Region
This section is not applicable to this site.

Pyramid Project # 2021-325 01/09/2023

3.2.6 Subsurface Structures
The Ashby’s Grocery site is located in a rural setting in which there are few subsurface public
utilities. The electrical utility is overhead. There are a few shallow telephone cables, but they do
not cross the source area. Any soil contamination present at the site is present in the former
UST and product dispenser areas. There are no municipal water or sewer lines or underground
storm drains. No other known artificial conduits are located within the source area. Potable
drinking water is provided from private water wells. No subsurface utilities are anticipated to
act as preferential pathways for petroleum migration.

3.2.7 Land Use
The Ashby’s Grocery site is currently zoned for commercial land use. The surrounding area
within 1,500 feet of the source area is zoned for farming and residential use.

3.3 Site Geology and Hydrogeology

Pyramid’s review of the 1985 Geologic Map of North Carolina yielded information concerning
local geology and hydrogeology. Based on this review, the site is located in the northwestern
portion of the Carolina Slate Belt Hydrogeologic Unit of North Carolina. The surface geology
consists of regional soils created by the weathering of underlying bedrock. The underlying
bedrock in the area is described in the Preliminary Explanatory Text for the 1985 Geologic Map
of North Carolina as metamorphosed granitic rock, map symbol CZg.

In general, both surface and groundwater flow directions are controlled by topographic
contours of land forms in the Piedmont Physiographic Province, with flow occurring
perpendicular to the contours from high to low elevations. Surface water from the subject
property generally flows to the north-northeast approximately 1,400 feet to an unnamed
tributary of Hyco Creek. The location of the site relative to the tributary is shown in Figure 1.

The hydro-geologic framework is unconfined groundwater present in the fractured bedrock
aquifer at a depth of about 26-30 feet below land surface (BLS). In drilling the monitoring and
recovery wells, the bedrock was encountered at a depth of approximately 25-30 feet BLS. The
bedrock has the potential to yield moderate volumes of water; however, the long-term yield
would depend upon the lateral continuity of bedrock fractures.

The site is located at the top of a topographic ridge. The results of the November 2016 gauging
event indicated that the Ashby’s Grocery site is located in a groundwater recharge area, and
that groundwater is flowing in several directions. Over 20 years of groundwater gauging, the
primary groundwater flow direction is to the north. The groundwater data from several
different years have shown fluctuations in water table depth and groundwater flow direction.
The movements of the contaminant plume over the 20 years of monitoring data show that the
greatest contaminant migration is to the northwest.

Pyramid Project # 2021-325 01/09/2023

Soil classifications were conducted by collecting split spoon samples at depth intervals during
groundwater monitoring well installation. The following is the generalized lithologic sequence
found in MW-1.

DEPTH DESCRIPTION (DW)
8" - 5' Red silty clay.
5' - 25' Red silty sand with some clay (saprolite).
25' - 30' Red silty sand w/ some clay and thin rock layers (saprolite)
30' - 40' Dark gray metamorphosed granitic rock.

These lithologies are consistent with those mapped by the North Carolina Geological Survey on
a regional basis. Two geologic cross-sections were developed by Salem Environmental in July
1996 from data collected during the CSA portion of the assessment, and are available is the CSA
report.

Based on the lithologic descriptions of split spoon samples collected during monitoring well
installation (see Table 3 for construction details), the site is underlain by interlayered saprolite
consisting of silty clays, sandy and clayey silts, and silty and clayey fine sands that appear to
display some lateral discontinuity. The in place weathered saprolite soils are underlain by
fractured metamorphosed granitic rock at depths ranging from 25 to 40 feet below land surface
(BLS). The hydrogeologic framework of the area covered by this assessment is likely of a
heterogeneous, unconfined nature. The bedrock has the potential to yield moderate volumes of
water; however, the long-term yield would depend upon the lateral continuity of the fractures.

The groundwater flow and hydraulic conductivity from the CSA are summarized below:
• Average depth to the static groundwater table is between 26 to 30 feet BLS.
• The average groundwater gradient reported in the CSA was 0.0052 ft. toward the north-
northeast.

Conducted on July 29 & 30, 1998, results of the 24-hour pump test, utilizing well RW-1, showed
an average hydraulic conductivity (K) value of 0.59 feet per day.

Groundwater level measurements have been recorded from the top of casing in MW-1 through
MW-16 with respect to an arbitrary benchmark of 100 feet. A summary of the groundwater
gauging data events is shown on Table 4. The average groundwater levels at the site are about
26 to 30 feet below land surface. Groundwater level measurements at the site demonstrate
that seasonal fluctuations in groundwater elevation and flow direction exist at the site.
Additionally, usage of private wells in the area may influence groundwater flow. The hydraulic
conductivity of the aquifer was calculated using the data obtained from the pump test, and the
average velocity was calculated to be 0.031 foot/day or 11.32 feet/year. The actual
groundwater flow velocity may be more or less than the calculated value depending on natural
fractures, influences of water recharge, and manmade features. The groundwater seepage

Pyramid Project # 2021-325 01/09/2023

velocity will not coincide with the rate of dissolved VOC migration due to the effects of
absorption, dilution, dispersion, retardation, and biodegradation.

3.4 CAP Implementation

The original CAP was designed to provide long-term soil and groundwater cleanup in the source
area using SVE and Pump & Treat technologies. The CAP was approved in 2002, but was not
installed mostly because of financial changes in the NC UST Trust Fund. From 2001 through
2006, Sparks/Pyramid performed sampling of the area supply wells and maintained contact
with the DEQ concerning concentration trends in the area.

In 2004, Pyramid/Sparks investigated whether the surrounding well users would agree to
connect to a community well system. The private water supply well users within 1,000 feet of
the site were interviewed and agreed with the concept. Pyramid prepared agreements that
were sent to all of the well owners within 1,000 feet of the site. The entire community was in
agreement in 2004 and all owners within 1,000 feet signed agreements to connect to a
community well.

At that time, the DEQ funding was not sufficient to pay for the community well project, and
further action on the community well was postponed. In 2006, the DEQ again requested
additional action at the site, and Sparks/Pyramid requested that the State again consider the
community well project. Pyramid pre-approved the implementation of sampling and
preparation of a New Technology Cleanup Plan for the site.

To implement New Technology Cleanup Plan, Pyramid re-submitted agreements to each of the
previous well owners and several additional residents within 1,200 feet of the site. Pyramid
performed the research and found that, within 1,000 feet, there were nine residential wells, and
within 1,500 feet there were an additional six supply wells. In 2006, new agreements were sent
to all parties within 1,000 feet of the site to seek their renewed agreement with the community
well project.

In 2006, Pyramid obtained most of the agreements within 1,000 feet of the site; however, the
store owner at the time, Mr. James Ivey, would not agree to connect. The revised CAP was
prepared in January 2007, and could not be finalized since Mr. Ivey would not connect to the
community well. Between January and October 2007, there were several correspondences
between the DEQ and Sparks about the troubles with the community well agreements.

Sparks Oil Co.: Ashby’s Grocery (Incident # 13501) - Groundwater Monitoring Report 11
Pyramid Project # 2021-325 01/09/2023

Pyramid made many appeals to Mr. Ivey and Mr. Ashby to sign the agreements without avail. In
March 2007, Mr. Ivey defaulted on his loan to Mr. Ashby, and Mr. Ashby became the property
owner. Pyramid/Sparks worked with Mr. James Ashby to secure his agreement with the
community well project. The agreement with Mr. Ashby was finally obtained in late November
2007.

The proposed change to the Corrective Action Plan was to provide source reduction using
Mobile Multi-Phase Extraction (MMPE) events, and to complete the community well project as
the long-term solution to reduce risk to the public.

As of January 2011, the community well project was again postponed due to the withdrawal of
agreement to operate and manage the Ashby’s community well by the initial contractor, Aqua
America (Aqua), a company which operated community well systems in NC as a private utility.

Aqua had stated that they would take over the system once it was built in 2004 and Aqua
stated the same again in 2006. When Pyramid resumed the project in 2009, Aqua still agreed to
take over the community well system once completed. Unfortunately, the company changed
with the economic climate at the time and decided not to continue with the project. Other
options were researched, but no opportunity to connect a community well or operate it came
to fruition. The long-term plan from that point on was to monitor and protect local supply well
users.

After completing the soil assessment and soil excavation in 2011 - 2012, Pyramid performed six
MMPE events and continues to conduct groundwater monitoring events at the site. The last
MMPE event was conducted from April 11 - April 15, 2016, and a total of 4,585 gallons of
contaminated groundwater were recovered from MW-1, MW-13, and MW-17.

4.0 SITE ASSESSMENT INFORMATION

4.1 Extent of Soil Contamination Initial soil assessment at the site was completed in the CSA, prepared by Salem Environmental
in 1996, and included a number of soil borings. Soil samples collected during UST closure
activities in 1994 and Geoprobe soil borings underneath the gasoline tanks of UST System #2
did not show detections of TPH over the 10 parts per million (ppm) action level for EPA Method
5030. Soil samples collected during the closure of UST System #1 showed levels of TPH in the
gasoline range that exceeded the action levels for EPA Method 5030 (>10 ppm). The tanks for
UST System #1 were formerly located between the store and the pump island. The highest TPH
levels were detected underneath the USTs and on the north sidewall of the excavation and
ranged from 243 - 430 ppm. The results of the assessment showed the area surrounding the

Sparks Oil Co.: Ashby’s Grocery (Incident # 13501) - Groundwater Monitoring Report 12
Pyramid Project # 2021-325 01/09/2023

pump island and former 550-gallon USTs contained petroleum contamination. The soil
sampling data are included in the CSA.

Additional soil assessment was conducted on July 13, 1998, by ENSCI. Samples from two
Geoprobe borings (GP-1 & GP-2) were collected on the north and south sides of the former UST
System #1 excavation area. The results of the analyses indicated no detections in the sample
collected from GP-1, but the GP-2 sample indicated levels of VPH (C9-C10 Aromatics) and
naphthalene which exceeded the maximum allowable Soil-to-Groundwater (STGW)
concentrations. The zone of soil contamination was approximated using the available soil
analytical data at the time and indicated that the extent of soil contamination was isolated to
the former UST System #1 area and pump island.

In June 2011, Pyramid installed 13 soil borings (SB-1 through SB-13) to further assess soil
conditions at the site. Laboratory results for the June 2, 2011 soil sampling event identified the
presence of targeted compounds at the concentrations above the Soil-to-Groundwater
Maximum Soil Contaminant Concentration Levels (MSCCs) in soil borings SB-3 and SB-4
installed in the area of the former pump island, as well as in SB-6 installed 10 feet east of the
former pump island. Concentrations of some targeted compounds were also above the
Residential MSCCs in SB-4. The laboratory results for the soil samples are summarized in the
Laboratory Results of Soil Samples table (Table A-1) included in Appendix A. The soil boring
locations are shown on the Soil Borings & MW-15 Location Map (Figure 4). Soil assessment
activities completed on June 2, 2011 identified residual contaminated soil in the area of the
former pump island located between former UST systems #1 and #3.

From January 16 – 25, 2012, Pyramid supervised the excavation of 397.80 tons of petroleum
contaminated soils at the Ashby’s Grocery site. The petroleum contaminated soils were
excavated from the area of the first UST system and the former product piping and dispensers,
were excavated for proper disposal as shown in the Soil Excavation Detail Map (Figure 5). Four
(4) composite disposal samples (CCS, DS1, DS2, and DS3) were collected from the excavated
soils as the work progressed. The laboratory results for soil samples DS1, DS2, and DS3 showed
detections above the DEQ initial action limits of 10 mg/kg to GRO and DRO. Laboratory results
of the disposal samples are summarized in the Summary of Disposal Soil Samples table (Table
A-2) included in Appendix A.

Five (5) post-excavation soil samples were collected from the limits of the soil excavation
(NSWS, ESWS, BSS, SSWS, and WSWS). The laboratory results of the risk-based analyses for soil
samples NSWS, ESWS, and SSWS did not detect any of the targeted compounds over laboratory
detection limits. The laboratory results for soil WSWS detected VOC compounds above
laboratory reporting limits, but below Soil-to-Groundwater (STGW) and Residential Maximum
Soil Contaminant Concentration (MSCC) Levels. The laboratory results for soil sample BSS
detected VOC compounds and VPH fractions above STGW and Residential MSCC levels.
Laboratory results for the risk-based soil samples are summarized in the Risk-Based Soil

Samples table (Table A-3) included in Appendix A. The post-excavation soil sample and cross-
section locations are shown in Figure 5. Soil cross-section S-S’ is shown in Figure 6.

The Ashby’s Grocery soil contaminant mass baseline of 479.77 kilograms (~ 1,057.54 lbs.) was
established based on the average soil contaminant concentrations detected during the 2011
Soil Assessment activities and estimated volume of contaminated soil above the STGW MSCCs.
The soil contaminant mass baseline calculation (Table A-4) is included in Appendix A.

4.2 Extent of Groundwater Contamination The most recent groundwater monitoring event was completed on February 2, 2022. Four (4)
water supply wells, eleven (11) monitoring wells, and one (1) recovery well were sampled
during the January 2020 groundwater monitoring event. Per NCDEQ request, all samples
collected during the February 2022 groundwater monitoring event were analyzed using the
expanded Standard Method 6200B that includes fuel oxygenates (ethanol, MTBE, TAA, TBA,
etc.) for the first time since the groundwater monitoring activities commenced at the site in
1994.

LABORATORY REPORT & CHAINS-OF-CUSTODY: Appendix B

Analytical results from the February 2022 sampling event indicate that high levels of dissolved
hydrocarbon compounds associated with gasoline are still present in groundwater at the site.
Table 5 presents a summary of analytical results for the groundwater samples collected from
the monitoring wells. The analytical results from the monitoring well sampling event are
presented in Appendix B along with the Chain-of-Custody (COC) form.

In February 2022, the concentrations of benzene, toluene, ethylbenzene, and xylenes (BTEX)
ranged from below detection limits in perimeter monitoring wells (MW-4, MW-8, and MW-12)
to 3,181 µg/L in MW-1. The detected BTEX concentrations in MW-1, MW-2, MW-13, MW-14,
and MW-15 indicate that there is still significant petroleum contamination present in
groundwater at the site.

The groundwater analytical results of the February 2022 sampling event detected
concentrations of MTBE at a level exceeding the 2L Groundwater Standard only in monitoring
well MW-5D. The deep well (MW-5D) has shown concentrations of MTBE above the 2L
Groundwater Standards since 1997. TAA and TBA, which are degradation byproducts of MTBE,
were detected at concentrations above the 2L Groundwater Standards in monitoring wells MW-
1, MW-2, MW-5D, and MW-14 in February 2022.

Petroleum compounds including naphthalene, 1,2,4-trimethylbenzene, isopropylbenzene, 1,2-
dichloroethane, and n-propylbenzene, were detected above 2L Standards in several monitoring
wells in February 2022. The concentrations of these compounds have generally remained the
same since January 2019.

Based on the most current groundwater sampling results, no compounds were detected above
the GCLs at the site. The past several years of groundwater analytical results show that the
groundwater contaminant plume is relatively stable and that contaminant concentrations have
generally remained the same since January 2019, indicating that active remediation activities
are necessary to decrease the contaminant concentrations below the 2L Groundwater
Standards, which are the NCDEQ cleanup goals for the Ashby’s Grocery incident.

The previous active remediation activities consisting of six MMPE events were conducted at the
site between June 2013 and April 2016. These MMPE events were instrumental in reducing the

Pyramid Project # 2021-325 01/09/2023

petroleum hydrocarbon mass and lowering the high concentrations of petroleum contaminants
below the GCLs within the surficial aquifer at the site.

4.2.2 Water Supply Well Sampling
SAMPLING DATE: February 2, 2022

WELLS SAMPLED: SW-3425, SW-3302, SW-3190, and Ledbetter-SW
Supply well SW-3464 could not be sampled because the residence
connected to the well was vacant and the power supply to the
well was most likely turned off.

Sparks Oil Co.: Ashby’s Grocery (Incident # 13501) - Groundwater Monitoring Report 16
Pyramid Project # 2021-325 01/09/2023

In the Lonnie Bowes (3425) supply well, chloroform (1.55 µg/L) and MTBE (0.249 µg/L) were
detected at low concentrations well below the 2L Groundwater Standards in February 2022.
The chloroform compound can be formed when chlorine or other well disinfectants react with
naturally occurring organic or inorganic matter in well water. Sparks Oil Company has been
providing bottled water to the Lonnie Bowes residence since March 2000 due to a 1,2-
dichloroethane detection. Concentrations of 1,2-dichloroethane have not been detected in the
Lonnie Bowes well since the May 2015 sampling event.

In February 2022, only MTBE was identified at a concentration of 1.66 µg/L in the Lawrence W.
Bowes (3190) supply well. The detected concentration of MTBE is well below the 2L
Groundwater Standard. MTBE was first detected in the water supply well in 2000 at a
concentration of 5.1 µg/L. The well has never shown any detection of MTBE at concentration
higher than 14 µg/L identified in 2002 and 2005. Since 2005, concentrations of MTBE have
decreased over time. MTBE concentrations in supply well 3190 have remained below 2 µg/L
since 2016.

No targeted compounds were identified in Ron Richmond (3302) and Keith Ledbetter supply
wells in February 2022. A summary of the supply well analytical results is presented in Table 6.
The analytical results from the supply well sampling are presented in Appendix B along with the
Chain-of-Custody (COC) form.

The analytical results from the water supply wells sampled in February 2022 indicated that
petroleum-related hydrocarbon concentrations were below the NCAC 2L Groundwater
Standards in all sampled supply wells.

November 2011. The estimated mass calculation spreadsheet is included in Appendix C. During
the November 2016 – February 2022 period, the estimated groundwater mass reduction rate
based on the average VOC concentrations in monitoring wells was 90.05%. Graph 3 shows
estimated groundwater contaminant mass vs. time. The groundwater remediation goals remain
cleanup to the NCAC 2L Groundwater Standards for all petroleum compounds.

4.2.4 GROUNDWATER REMEDIATION After the soil assessment and soil excavation in 2011 - 2012, Pyramid has performed six MMPE
events and continues to conduct groundwater monitoring events at the site. The last MMPE
event was conducted from April 11 - April 15, 2016, and a total of 4,585 gallons of
contaminated groundwater were recovered from MW-1, MW-13, and MW-17. The site has
been in monitored natural attenuation since that time. The MMPE events were instrumental in
reducing high petroleum contaminant concentrations below GCLs and moving the site closer to
regulatory closure.

5.0 FREE PRODUCT

The Ashby’s Grocery site has not displayed free-phase petroleum product in any of the existing

6.0 MONITORED NATURAL ATTENUATION

Since the soil assessment and soil excavation in 2011 - 2012, Pyramid has performed six MMPE
events and continues to conduct groundwater monitoring events at the site. The last MMPE
event was conducted from April 11 - April 15, 2016, and a total of 4,585 gallons of
contaminated groundwater were recovered from MW-1, MW-13, and MW-17. The site has
been in monitored natural attenuation since that time.

7.0 CONCLUSIONS AND RECOMMENDATIONS

The most recent groundwater monitoring activities for the Ashby’s Grocery site were
completed in February 2022. The conclusions of the completed activities and data are
presented below.

• The Ashby’s Grocery soil contaminant mass baseline of 479.77 kilograms (~ 1,057.54
lbs.) was established based on the average soil contaminant concentrations detected
during the 2011 Soil Assessment activities.

• The Ashby’s Grocery groundwater mass baseline of 3.42E+10 µg was established based
on the November 2016 average groundwater contaminant concentrations.

• The previous active remediation activities consisting of six MMPE events were
conducted at the site between June 2013 and April 2016. These MMPE events were
instrumental in reducing the petroleum hydrocarbon mass and lowering the high
concentrations of petroleum contaminants below the GCLs within the surficial aquifer at
the site.

• In the Lonnie Bowes (3425) supply well, chloroform (1.55 µg/L) and MTBE (0.249 µg/L)
were detected at low concentrations below the 2L Groundwater Standards in February
2022. The Lawrence W. Bowes (3190) supply well only showed MTBE at a concentration
of 1.66 µg/L, which is below the 2L Groundwater Standard for MTBE of 20 µg/L. The
chloroform compound can be formed when chlorine or other well disinfectants react
with naturally occurring organic or inorganic matter in well water. Sparks Oil Company
has been providing bottled water to the Lonnie Bowes residence since March 2000 due
to a 1,2-dichloroethane detection. 1,2-dichloroethane has not been detected in the
Lonnie Bowes well since the May 2015 sampling event.

• No targeted compounds were identified in Ron Richmond (3302) and Keith Ledbetter
supply wells in February 2022.

Sparks Oil Co.: Ashby’s Grocery (Incident # 13501) - Groundwater Monitoring Report 19
Pyramid Project # 2021-325 01/09/2023

• On February 2, 2022, monitoring wells MW-1, MW-2, MW-4, MW-5D, MW-8, MW-10, ,
MW-12, MW-13, MW-14, MW-15, and RW-1 were gauged and groundwater samples
were collected for analysis for VOCs by the expanded Standard Method 6200B that
includes fuel oxygenates (ethanol, MTBE, TAA, TBA, etc.) for the first time since the
groundwater monitoring activities commenced at the site in 1994.

• In February 2022, the concentrations of benzene, toluene, ethylbenzene, and xylenes
(BTEX) ranged from below detection limits in perimeter monitoring wells (MW-4, MW-8,
and MW-12) to 3,181 µg/L in MW-1. The detected BTEX concentrations in MW-1, MW-
2, MW-13, MW-14, and MW-15 indicate that there is still significant petroleum
contamination present in groundwater at the site.

• The groundwater analytical results of the February 2022 sampling event detected
concentrations of MTBE at a level exceeding the 2L Groundwater Standard only in
monitoring well MW-5D. The deep well (MW-5D) has shown concentrations of MTBE
above the 2L Groundwater Standards since 1997. TAA and TBA, which are degradation
byproducts of MTBE, were detected at concentrations above the 2L Groundwater
Standards in monitoring wells MW-1, MW-2, MW-5D, and MW-14.

• Petroleum compounds including naphthalene, 1,2,4-trimethylbenzene,
isopropylbenzene, 1,2- dichloroethane, and n-propylbenzene, were detected above 2L
Standards in several monitoring wells in February 2022. The concentrations of these
compounds have generally remained the same since January 2019.

Based on the lingering groundwater contaminant concentrations above the 2L Groundwater
Standards, which have generally stay the same since January 2019, and the presence of private
water supply wells in the area, the site remains high risk. The remediation goals are to reduce
dissolved groundwater contamination below the NCAC 2L Groundwater Standards in the source
area and the weathered rock and bedrock zones of the aquifer. Pyramid recommends the
following:
• Continued annual groundwater monitoring activities.

• The application of an in-situ chemical oxidant (e.g. PersulfOx by Regenesis) at the site to
address the persistent groundwater contaminant concentrations above the 2L Groundwater
Standards. Prior to the full-scale implementation of the oxidant at the site, a pilot study
should be conducted to determine the oxidant effectiveness and radius of influence.
