1.0 INTRODUCTION
At the request of Donna Fitzgerald of the Grocery Bag, and in accordance with the provisions of North
Carolina Administrative Code, Title 15A, Subchapter 2L, Section .0110 (Monitoring), East Coast
Environmental, P.A. (ECE), of Raleigh, North Carolina, has prepared this “Report for Groundwater
Monitoring” for petroleum contaminated groundwater on and adjacent to the Grocery Bag (Facility ID #
0-032284); hereinafter, referred to as the Site, located at 4879-A Highway 42 East, Clayton, Wake
County, North Carolina (Section A, Figure 1). A Site map (Section A, Figure 2) shows the location of
the Site & the locations of all monitoring wells associated with the Site, as well as the UST locations.
The Site contains three petroleum Underground Storage Tank (UST) systems that were installed for the
retail sale of gasoline. The Site’s UST systems were installed during 1993 and included two 8,000-
gallon gasoline tanks and one 12,000-gallon gasoline tank that are currently registered as being owned
by the Grocery Bag. See Section A, Figure 2 for the Site map indicating UST system locations.
ECE mobilized to the Site on September 3, 2009 for the purpose of performing a Site check. The
suspected release was located on top of the 12,000-gallon tank and therefore it was determined that
groundwater samples should be collected in areas as close to the tank as possible in lieu of the collection
of samples adjacent to the product lines and dispensers.
Analytical results for the groundwater samples submitted by ECE for laboratory analysis by EPA
method 6200B detected targeted volatile organic compounds at concentrations more than their
maximum allowable levels in groundwater as set forth in 15A NCAC 2L .0202. The presence of
petroleum related contaminants at elevated levels indicated that a petroleum release had occurred.
However, the source of the petroleum release (leaking flex connector in 12,000-gallon UST sump) was
identified and repaired.
After the Site Check, the Grocery Bag contracted ECE to complete a Phase I Limited Site Assessment
(Phase II LSA) Report (dated December 18, 2009). The North Carolina Department of Environment
and Natural Resources-Fayetteville Regional Office (NCDENR-FaRO) issued a September 29, 2014
Notice of Regulatory Requirements (NORR) letter to Mr. Tommy Fitzgerald of the Grocery Bag to
comply with the requirements of 15A NCAC 2N .0706, 15A NCAC 2L .0106(c) and 2L .0106(g).
Mr. Fitzgerald responded by directing ECE to complete a Comprehensive Site Assessment (CSA) report
(dated December 14, 2015) that was subsequently reviewed and approved by the NC-DEQ-FaRO. After
review, the NC-DEQ-FaRO requested that Mr. Fitzgerald perform a Report for Groundwater Monitoring

that was completed during 2016. This most recent 2023 groundwater monitoring event was requested
by Mr. Ken Curry of the NC-DEQ Fayetteville Regional Office in a Notice of Regulatory Requirement
letter issued to Donna Fitzgerald on August 23, 2023.
Currently the Site is classified as “intermediate risk” due to the presence of surface water bodies located
within 500-feet of the Site in two directions.
1.1 Previous Groundwater Sampling Events
1.1.1 Comprehensive Site Assessment
Historical groundwater sampling events occurred between March and October 2015 after the NC-DENR
instructed Mr. Fitzgerald to complete a CSA. ECE mobilized to the Site on March 12-13, 2015 to install
four additional permanent monitoring wells designated as MW-2, MW-3, MW-4, and MW-5 all of
which were located on-Site. A summary of the well construction details is included in Section B Table
3. ECE returned to the Site on March 18, 2015 to sample the five monitoring wells installed to date for
inclusion in this CSA. The groundwater samples collected from the monitoring wells were submitted
for analysis by EPA Methods 6200B (volatile organic compounds), 504.1 (EDB), 3030c (total lead) and
the MADEP-VPH methods.
Data for the groundwater samples revealed the presence of targeted compounds in the samples collected
from all five groundwater monitoring wells. Samples collected from these wells were also found to
contain one or more targeted contaminants at levels above their maximum allowable concentrations in
groundwater as defined by 15A NCAC 2L .0202.
May 17, 2015 Groundwater Monitoring Event
The next phase of groundwater sampling was conducted during May 2015 for completion of the CSA
and included the installation of additional monitoring wells MW-6 and MW-7 at on-Site locations. A
summary of the well construction details is included in Section B Table 3. These wells were required
after reviewing the results for the March 2015 monitoring event which revealed that the groundwater
contaminant plume may have migrated offsite and under NC 42 to the south. Therefore, to complete
the CSA groundwater samples were subsequently collected from monitoring wells MW-6 and MW-7
after their installation. The groundwater samples collected from the monitoring wells were submitted
for analysis by EPA Methods 6200B (volatile organic compounds), 504.1 (EDB), 3030c (total lead) and
the MADEP-VPH method. Analytical results for the samples collected from MW-6 showed no

contaminants targeted by any of these test methods while the samples collected from MW-7 showed
numerous targeted contaminants at levels above their maximum allowable concentrations in
groundwater as defined by 15A NCAC 2L .0202. The analytical results for this sampling event confirm
that the groundwater contaminant plume has migrated offsite and under NC 42 to the south and defined
its extent to the east.
In summary, as of May 2015 data for the groundwater samples obtained from wells MW-1, MW-3,
MW-4, MW-5, and MW-7 showed the presence of targeted volatile organic compounds in these samples
at levels above their maximum allowable concentrations in groundwater as defined by 15A NCAC 2L
.0202. Analytical results for the samples collected from MW-2 and MW-6 were all below their
maximum allowable concentrations in groundwater as defined by 15A NCAC 2L .0202.
September/October 2015 Groundwater Monitoring Event
Th next phase of groundwater sampling was conducted during September and October 2015 for
completion of the CSA and included the installation of shallow wells MW-8, MW-9 and MW-10 and
deep profile well DW-1. MW-8 was installed on-Site to define the western extent of groundwater
contamination while MW-9 and MW-10 were installed off-Site and south of NC 42 to define the
downgradient extent of groundwater contamination. Finally, DW-1 was installed on-Site and adjacent
to MW-7 at the location indicated in Figure 2 to define the horizontal and vertical extent of groundwater
contamination. Therefore, to complete the CSA groundwater samples were subsequently collected from
monitoring wells MW-8, MW-9, MW-10, and DW-1. The groundwater samples collected from these
monitoring wells were submitted for analysis by EPA Methods 6200B (volatile organic compounds),
504.1 (EDB), 3030c (total lead) and the MADEP-VPH method. Analytical results for the groundwater
samples obtained from wells MW-8 and MW-9 showed the presence of targeted volatile organic
compounds in these samples at levels above their maximum allowable concentrations in groundwater as
defined by 15A NCAC 2L .0202.
In summary, data for the groundwater samples obtained from wells MW-1, MW-3, MW-4, MW-5, MW-
7, MW-8, and MW-9 showed the presence of volatile organic compounds in these samples at levels
above their maximum allowable concentrations in groundwater as defined by 15A NCAC 2L .0202 and
10 times the 15A NCAC 2B Standards.
Section B, Table 2 is a summary of the combined groundwater analytical results for all historical
sampling events.

Upon review of the data obtained by the CSA activities described above, it was evident that the
horizontal and vertical extent of the groundwater contaminant plume was adequately defined to the 15A
NCAC 2L standards for groundwater and 10 times the surface water standards wet forth at 15A NCAC
2B. The NC-DEQ followed up with a request to complete a monitoring event which included all the
wells installed to date be performed during June 2016.
June 2016 Groundwater Monitoring Event
Groundwater samples were collected from monitoring wells MW-1, 3, 4, 5, 6, 7, 8, 9, 10, and DW-1 on
June 13, 2016. All samples were collected using disposable PE bailers after the monitoring wells were
purged of either a minimum of three volumes of water calculated to be standing in the wells or purged to
dryness (whichever occurred first). Samples collected from all wells were submitted for chemical
analysis by SM6200B.
Results of chemical testing by SM6200B for groundwater samples collected from the monitoring wells
located on and around the Site showed the presence of targeted compounds in samples retained from
monitoring wells MW-1, MW-3, MW-4, MW-5, MW-7, MW-8, MW-9, and DW-1.
Numerous compounds were detected at levels more than their respective Maximum Allowable
Concentrations:
• Benzene was present in samples from wells MW-1, MW-3, MW-4, MW-5, MW-7, MW-8, MW-
9 and DW-1 at concentrations of 62, 83, 11, 520, 1,500, 3,600, 35 and 1.8 µg/L respectively,
• Ethylbenzene was found in samples from well MW-7 (1,500 µg/L),

March 2022 Groundwater Monitoring Event
The March 2022 groundwater monitoring event was requested by Mr. Ken Curry of the NC-DEQ
Fayetteville Regional Office in a Notice of Regulatory Requirement letter issued to Donna Fitzgerald on
February 25, 2022. In response, groundwater samples were collected from monitoring wells MW-1, 2, 3,
4, 5, 7, 9 and 10 on March 14, 2022. Monitoring wells MW-6, MW-8 and DW-1 were not included
because these wells had been destroyed as the result of recent road widening activities in front of the
store building. The remaining wells that could be included in the sampling event were sampled using
disposable PE bailers after the monitoring wells were purged of either a minimum of three volumes of
water calculated to be standing in the wells or purged to dryness (whichever occurred first). Samples
collected from all wells were submitted for chemical analysis by SM6200B.
Results of chemical testing by SM6200B for groundwater samples collected from the monitoring wells
located on and around the Site showed the presence of targeted compounds in samples retained from
monitoring wells MW-1, MW-2, MW-3, MW-4, MW-5, MW-7, MW-8, and MW-9.
Numerous compounds were detected at levels more than their respective Maximum Allowable
Concentrations:
• Benzene was present in samples from wells MW-1, MW-2, MW-3, MW-4, MW-5, MW-7, and
MW-9 at concentrations of 890, 45, 11, 1.8, 200, and 360 µg/L respectively;
• Ethylbenzene was found in the sample from well MW-7 (1,300 µg/L);
• Isopropyl-benzene was shown in well MW-7 at a level of 87 µg/L;

June 2023 Groundwater Monitoring Event
1.2.1 Groundwater Sampling Event – September 18, 2023
As discussed previously this most recent September 2023 groundwater monitoring event was requested
by Mr. Ken Curry of the NC-DEQ Fayetteville Regional Office in a Notice of Regulatory Requirement
letter issued to Donna Fitzgerald on August 23, 2023. In response, groundwater samples were collected
from monitoring wells MW-1, 2, 5, 9 and 10 on September 18, 2023. Monitoring wells MW-3, MW-4,
MW-6, MW-7, MW-8, and DW-1 were not included because these wells had been destroyed as the
result of recent road widening activities in front of the store building. The remaining wells that could be
included in the sampling event were sampled using disposable PE bailers after the monitoring wells
were purged of either a minimum of three volumes of water calculated to be standing in the wells or
purged to dryness (whichever occurred first). Samples collected from all wells were submitted for
chemical analysis by SM6200B.
1.2.2 Well Gauging
Well gauging was performed to determine the groundwater elevation within each well, and for the
calculation of appropriate purge volume(s) for each well prior to sampling. After decontamination
utilizing an Alconox® and deionized water solution, an electronic water level indicator was lowered into
each well to determine the depth to groundwater beneath the top of casing (TOC) of each well. Each
well associated with the Site was gauged on September 18, 2023. Depths to groundwater ranged from
2.05 feet (ft) in MW-1 to 3.08 ft in MW-5. Based on gauged of the wells, groundwater was determined
to flow from the north to the south through the Site, with a slight westerly component. Figure 4 depicts
the gradient based on the September 2023 gauging event. This flow direction is in general agreement
with the groundwater flow direction established during the 2015, 2016 and 2022 monitoring events
1.2.3.2 Well Purging
The groundwater within each well included in this sampling event was purged of a pre-determined
volume to allow for infiltration of representative groundwater, and thus collection of representative
groundwater samples. All wells were purged of a minimum of three well volumes prior to sampling,
unless the well was purged to a dry state prior to the removal of three volumes of water. After purging,
the groundwater level within each well was allowed to recharge to within 80% of the static level initially
observed before sampling of the well(s) was performed. Purging of each well was accomplished using
separate disposable polyethylene (PE) bailers.

1.2.3.3 Groundwater Sample Collection
Representative groundwater samples were collected from each well targeted for sampling after proper
purging and recharge of the wells. The collection of groundwater samples was performed in accordance
with established EPA and North Carolina Division of Waste Management (NC-DWM) protocols for the
collection of groundwater samples. ECE modeled the sampling procedures after those set forth in the
“Underground Storage Tank Section Guidelines for Site Checks, Tank Closure, and Initial Response and
Abatement” prepared by the NC-DEQ-UST Section.
1.2.3.4 Sample Storage and Transport
All samples collected during this sampling event were properly contained in pre-washed, laboratory
grade sample containers. The sample containers utilized in this sampling event were provided by
Environmental Conservation Laboratories, Inc. (ENCO), a licensed analytical laboratory located in
Cary, NC (NC-DWQ certification# 591).
Samples collected for volatile organic analyses (SM6200B) were enclosed in 40-ml "VOAs", pre-
preserved with 1:1 hydrochloric acid (HCL). The headspace was removed from the samples prior to
capping.
After the collection of each sample, all containers were properly labeled with the sample designation,
sample date and time, and analysis requested. Information was recorded on a chain-of-custody form,
identifying each sample, and the analysis (or analyses) requested for the sample(s). The samples were
then placed in a cooler on ice pending delivery to the laboratory.
The samples collected on September 18, 2023 were relinquished to the lab courier on September 19,
2023 with all appropriate chain-of-custody documentation.
1.2.3.6 Analytical Methodology
Groundwater samples collected from the monitoring wells located on and adjacent to the Site were
analyzed for petroleum hydrocarbons and related petroleum additives. Samples collected from
monitoring wells sampled during the September 2023 sampling event were analyzed by SM6200B, a US

EPA approved method for testing of groundwater samples. SM6200B targets low-boiling-point volatile
petroleum hydrocarbons, such as those typical of gasoline and other light hydrocarbons. Samples
retained from the pond across NC Highway 42 were also analyzed by SM6200B. The pond sample
location is included in Figure 2.
1.2.2 Analytical Results – Groundwater Samples (September 18, 2023)
1.2.2.1 SM6200B
Results of chemical testing by SM6200B for groundwater samples collected from the monitoring wells
located on and around the Site showed the presence of targeted compounds in samples retained from
monitoring wells MW-1, MW-2, MW-5, and MW-9 (Table 1).
Numerous compounds were detected at levels more than their respective Maximum Allowable
Concentrations:
• Benzene was present in samples from wells MW-1, MW-2, and MW-5 at concentrations of
2,870, 927 and 113 µg/L respectively;
• Isopropyl-ether was shown in well MW-1 at a level of 98.7 µg/L;
• Naphthalene was found in samples from wells MW-1, MW-2, MW-5, and MW-9 at levels of

that overall contaminant concentrations for the September 2023 monitoring event have increased when
compared to historical groundwater monitoring events completed during 2015, 2016 and 2022. The data
charts are included in the back of Section B.
1.2.2.2 Surface Water Sampling Results
No sample was collected from the pond located across Highway 42 for this groundwater monitoring
event.
1.3 Current Plume Information
Based on analytical data for the September 2023 groundwater sampling event levels of one or more
compounds were present in samples collected from MW-1, MW-2, and MW-5 at levels more than their
Maximum Allowable Concentrations defined by the 2L Standards. The estimated area encompassed by
the extent of 2L Standard violations in the surficial aquifer based on the September 2023 groundwater
data measured as much as 56,600 square feet, or 1.3 acres. Figures 2 and 3 depict the approximate
lateral extent of 2L Standard violations on and in the vicinity of the Site based on the September 2023
sampling event. Contaminant concentrations detected in the wells related to the release at the site are
generally are lower than those from the 2015 and 2016 sampling events.
1.4 Proposed Remedial Actions
At this time there has been no Corrective Action Plan (CAP) prepared for remediation of soils and
groundwater at the Site.

1.5 Groundwater Conditions
1.5.1 Proximity to Potential Receptors
There are no longer any water supply wells located within a 1,000-foot radius of the Site. However, the
Site is currently classified as “intermediate risk” due to the presence of surface water bodies located
within 500-feet of the Site in two directions. See Section A, Figure 1.
1.5.2 Groundwater Flow
Groundwater elevation data obtained during the September 2023 sampling event showed that
groundwater flows through and off the Site from north to south. This data also demonstrates that
groundwater flow is generally consistent with local topography and flowing towards the pond located
across NC 42 and to the southeast, south, and southwest. The gradient as modeled based on
groundwater elevation measurements obtained on September 18, 2023 is depicted on Figure 4.

2.0 CONCLUSIONS AND RECOMMENDATIONS
The results of the analytical data for the September 2023 groundwater sampling event show the
continued presence of targeted compounds at levels exceeding their respective Maximum Allowable
Concentrations in select wells located on the Site. These compounds included:
• Benzene was present in samples from wells MW-1, MW-2, and MW-5 at concentrations of
2,870, 927 and 113 µg/L respectively;
• Isopropyl-ether was shown in well MW-1 at a level of 98.7 µg/L;
• Naphthalene was found in samples from wells MW-1, MW-2, MW-5, and MW-9 at levels of
154, 13.5, 107 and 27.7 µg/L, respectively;
• Tert-amyl Alcohol was found in samples from wells MW-1 and MW-5 at levels of 809 and 236
µg/L, respectively.
The estimated area encompassed by the extent of 2L Standard violations in the surficial aquifer based on
the September 2023 groundwater data measured as much as 56,600 square feet, or 1.3 acres. Figures 2
and 3 depict the approximate lateral extent of 2L Standard violations on and in the vicinity of the Site
based on the September 2023 sampling event. Contaminant concentrations detected in the wells related
to the release at the site are generally are lower than those from the 2015 and 2016 sampling events.
Three time vs. historical analytical data charts have been prepared for groundwater monitoring wells
MW-1, MW-2, and MW-5. Except for the chart for MW-5, the charts for MW-1 and MW-2 indicate
that overall contaminant concentrations for the September 2023 monitoring event have increased when
compared to historical groundwater monitoring events completed during 2015, 2016 and 2022. The data
charts are included in the back of Section B.
Groundwater elevation data obtained during the June 2016, March 2022 and September 2023 sampling
events show that groundwater flows through and off the Site from north to south, with a slight easterly
component. This data also demonstrates that groundwater flow is generally consistent with local
topography.
Recommendations
Based on the results of the September 2023 sampling event ECE recommends that monitoring continue
to take place on an annual basis. ECE also recommends replacing monitoring wells MW-4, MW-7 and
MW-8 if the NC-DEQ considers the incident to be high enough risk.

The next groundwater sampling event should be scheduled for September 2024. ECE appreciates the
opportunity to be of assistance with this project. ECE recommends that a copy of this monitoring report
be submitted to the North Carolina Department of Environment and Natural Resources, Division of
Water Quality, Fayetteville Regional Office to the attention of Mr. Ken Currie.
