CATLIN Project No. 221050 2 May 2023
2.0 EXECUTIVE SUMMARY

The Kelly’s Grocery site is located at 3474 NC Highway 751, Apex, Chatham
County, North Carolina. Three underground storage tanks (USTs) were previously
operated at the site. The original UST is reported to have been removed in the late
1930s and the presence of gasoline was reported in a water supply well near the
tank around the time of removal. The original UST was replaced by two 550-gallon
USTs, which were later removed in April 1990. Total petroleum hydrocarbon (TPH)
constituents exceeding State Action Levels were detected in soil samples collected
from beneath one of the USTs during the 1990 tank removal activities.

The purpose of this report is to document the latest remediation efforts and
groundwater sampling activities. On February 28, 2023, CATLIN Engineers and
Scientists (CATLIN) personnel supervised an aggressive fluid vapor recovery
(AFVR) event conducted by Eastern Environmental Management (EEM). A total of
745 gallons of impacted groundwater were removed and a calculated 3.95 pounds
of petroleum vapors (equivalent to 0.63 gallons of petroleum) were emitted.

CATLIN returned to the site on April 12, 2023 and measured groundwater at
approximately 14 feet below top of casing (BTOC) across the site in the shallow,
Type II wells, and at 20.21 feet BTOC in the deep, Type III well. Groundwater
samples were collected from nine monitoring wells and one water supply well
(influent location). The samples were submitted for laboratory analysis of volatile
organic compounds (VOCs) per Standard Method (SM) 6200B plus ethylene
dibromide (EDB), methyl tert-butyl ether (MTBE), diisopropyl ether (DIPE).

Laboratory results for the groundwater samples did not indicate any dissolved
petroleum constituents above their laboratory reporting limits in the samples
collected from MW-4, MW-5, MW-6, MW-7R, MW-8D, and MW-9. Several VOCs
were detected in the MW-1R, MW-2 and MW-3R samples at concentrations greater
than those established in Title 15A of the North Carolina Administrative Code,
Subchapter 2L, Section .0202 Groundwater Quality Standards (2L GWQS), but
below the Gross Contaminant Levels (GCL).

Benzene was detected at a concentration above its 2L GWQS in the influent sample
from water supply well WSW-7. The concentration has decreased since the previous
sampling event in July 2022.

Benzene, toluene, ethylbenzene, and total xylenes (BTEX) concentrations have
generally increased in samples from monitoring wells MW-2 and MW-3R since the
previous sampling event in July 2022, while those in MW-1R have fluctuated
(CATLIN, 2022B).

CATLIN recommends to:
• Install a shallow and a deep monitoring well in the vicinity of the on-site water
supply well; and
• Conduct a semi-annual sampling event in October 2023. During the
sampling event, it is recommended to purge the on-site water supply well for
NCDEQ; 5656_Kelly's Grocery CATLIN Engineers and Scientists
CATLIN Project No. 221050 3 May 2023
a minimum of 30 minutes and determine if there is an additional sampling
point right before the home treatment system. A sample from the on-site
water supply well should also be collected downstream of the treatment
system.

3.0 SCOPE OF SERVICES

The scope of services for this report was performed in general accordance with
CATLIN proposal number 221050.04P, dated February 20, 2023. Services were
authorized by the North Carolina Department of Environmental Quality (NCDEQ)
Task Authorization (TA) #04, accepted on February 20, 2023 and Contract Number
N122019D.

The approved scope of services for this Task Authorization included to:
• Coordinate and oversee an AFVR event utilizing monitoring wells MW-2 and
MW-3R as extraction points;
• Approximately 30 days after the AFVR event, collect groundwater samples
from nine monitoring wells (MW-1R, MW-2, MW-3R, MW-4 through MW-6,
MW-7R, MW-8D, and MW-9);
• Collect a groundwater sample from the water supply well WSW-7 pre-
treatment system (influent);
• Analyze 12 water samples (nine monitoring well samples, one water supply
well sample, one field blank, and one trip blank) per SM 6200B (including
EDB, MTBE, and DIPE); and
• Prepare and submit a monitoring report summarizing the findings.

The scope of services was conducted in general accordance with the approved TA.

4.0 SITE HISTORY AND CHARACTERIZATION

The Kelly’s Grocery site is located at 3474 NC Highway 751, Apex, Chatham
County, North Carolina (Figures 1 and 2). Summarized available historical sampling
and gauging data from previous consultants are provided in Appendix A. Site
photographs are presented in Appendix B.

4.1 UST OWNER AND OPERATOR INFORMATION

According to historical reports, ownership of the former USTs is attributed to
an unknown oil company. H.O. Kelly, Sr. operated the USTs until the 1970s
(Lawrence, 1991).

Available information regarding UST owners and operators is presented in
Table 1.

4.2 UST INFORMATION

Three USTs were reportedly utilized on-site, which operated as a community
grocery store with retail fuel sales for approximately 50 to 60 years. One
NCDEQ; 5656_Kelly's Grocery CATLIN Engineers and Scientists
CATLIN Project No. 221050 4 May 2023
gasoline UST of unknown capacity was reported to be located along the
northern side of the store building. This UST was removed in the late 1930s
and the presence of gasoline was discovered in a nearby potable water
supply well around the same time. Two 550-gallon gasoline replacement
USTs were installed in the late 1930s to the south of the store building and
were removed from the site in April 1990 (Lawrence, 1991; S&ME, 2013).

Available UST system information is presented in Table 1 and illustrated on
Figure 3.

4.3 CONTAMINANT SOURCE INVENTORY

According to previous reports, the presence of gasoline was reported in a
potable water supply well located near the original gasoline UST around the
time of its removal (S&ME, 2013). The two replacement gasoline USTs were
removed in April 1990 and analytical results from soil samples collected
beneath one UST during the excavation revealed TPH up to 370 parts per
million (ppm) (Law & Co., 1990; AES, 1991).

4.4 SITE CHARACTERISTICS

The small parcel containing the former store is currently owned by David and
Wanda Johnson, who also own the larger surrounding parcel which contains
a residence, several outbuildings, and a pond. NC Highway 751 runs along
the western property boundary of both parcels.

4.5 OWNERS AND OCCUPANTS OF ADJOINING/NEARBY PROPERTIES
AND LAND USE

Properties in the site vicinity are a mix of rural residences, agricultural land,
and commercial businesses. Properties to the north appear to be residences,
and woodland is located to the east. D&B Farms is located across NC
Highway 751 to the west, as is a parcel owned by Time Warner Cable
Southeast, LLC. Directly south are residential properties and further south
and southwest are plant nurseries and agricultural land.

4.6 RECEPTOR INFORMATION

Conducting a receptor survey was outside the scope of this monitoring event.
A review of historical files available on the NCDEQ Waste Management
Online Database (aka Laserfiche) indicates that the last receptor survey for
the Kelly’s Grocery site was conducted in 2020 by S&ME, Inc. (S&ME).

According to S&ME (2020), municipal water is not available to the site or
surrounding area. Three active water supply wells have been identified within
500 feet of the source area, one of which (WSW-7) is located on the adjacent
parcel which is also owned by the subject site property owner. Two ponds
were also identified within 500 feet of the source area.
NCDEQ; 5656_Kelly's Grocery CATLIN Engineers and Scientists
CATLIN Project No. 221050 5 May 2023

As indicated by the property owner, the water from WSW-7 is pumped
through a home water filtration system prior to use. CATLIN determined that
the system is a General Electric whole house water filtration system (Model
Number GXWH20S). The property owner indicated that he previously used
just a sediment filter but has replaced that with a carbon filter. He typically
changes the filters every couple of months. Photographs of the water filtration
system were included in previous reports.

Potential receptors are illustrated on Figure 2 and receptor information is
shown in Table 2.

4.7 PREVIOUS INVESTIGATIONS AND REMEDIAL ACTIVITIES

Soil contamination was discovered in 1990 during removal of two 550-gallon
gasoline USTs. A sample collected from beneath one tank revealed TPH
concentrations up to 370 ppm, above State Action Levels. Three monitoring
wells were installed in August 1990 and analytical results from samples
collected confirmed groundwater impacts from the USTs (AES, 1991).

In December 1990, Applied Environmental Services, Inc. (AES) advanced
multiple borings at the site in the area of the former dispensing pumps, along
the western portion of the building, in the area of the former UST that was
located on the north side of the building, and in the area of the replacement
USTs on the south side of the building. Soil contamination exceeding the
State Action Levels for TPH was revealed in three borings located near the
former dispensing pumps and in the area of the former northern UST (AES,
1991).

AES completed a Comprehensive Site Assessment (CSA) report in May
1992. Field activities associated with the CSA included the installation of
Type II monitoring wells MW-3 through MW-7, and one Type III monitoring
well (MW-8D). Groundwater samples collected from the monitoring wells
revealed several petroleum constituent concentrations above the 2L GWQS
in the samples collected from wells MW-1 and MW-2 (S&ME, 2013).

AES also prepared a Corrective Action Plan (CAP), dated June 26, 1992,
recommending a pump and treat system using diffused aeration followed by
soil flushing as the remedial choice for the site. Due to lack of historical
information, it is unknown if this CAP was approved or implemented (S&ME,
2013).

Multiple monitoring events have been conducted by various consultants
between 2007 and 2020 and during this time, monitoring wells MW-1, MW-3,
and MW-7 were replaced with MW-1R, MW-3R, and MW-7R. Petroleum
contaminant concentrations exceeding the 2L GWQS have generally
persisted in monitoring wells MW-1R, MW-2, and MW-3R; however,
concentrations have remained below GCL. Water supply well WSW-7 has
NCDEQ; 5656_Kelly's Grocery CATLIN Engineers and Scientists
CATLIN Project No. 221050 6 May 2023
historically had detections of benzene and toluene (2010) but these were not
above the corresponding Environmental Protection Agency (EPA) Maximum
Contaminant Levels (MCLs) (S&ME, 2013; 2020).

CATLIN has conducted groundwater sampling in June 2021, December
2021, January 2022, and July 2022. No analyzed compound concentrations
were detected above the laboratory reporting limit in the samples from
monitoring wells MW-4, MW-5, MW-6, MW-7R, MW-8D, or MW-9. Several
petroleum constituents were detected above 2L GWQS in the samples
collected from MW-1R, MW-2, and MW-3R; however, they were all below
their respective GCLs. No analyzed compound concentrations were detected
above the laboratory reporting limit in the sample from water supply well
WSW-5. Benzene was reported above its 2L GWQS in the WSW-7 influent
sample in December 2021 and July 2022. Benzene was also detected in the
WSW-7 effluent sample in December 2021 but was below the method
detection limit in January and July 2022. Slug test analysis conducted in June
2021 resulted in hydraulic conductivities of 0.02533 feet/day and 0.2839
feet/day at wells MW-2 and MW-3R, respectively. Results from the predictive
groundwater modeling indicated that non-compliant analyte concentrations
should not migrate beyond 200 feet from MW-3R. Based on the model
results, it was determined that water supply wells WSW-7 and WSW-8
should not be impacted (CATLIN, 2022A).

Available summarized historical data from previous consultants are
presented in Appendix A.

5.0 REGIONAL AND SITE GEOLOGY AND HYDROGEOLOGY

5.1 SOIL AND BEDROCK

As defined in the Geologic Map of North Carolina, published by the North
Carolina Department of Natural Resources and Community Development
(1985), the site lies within the Triassic Basin of the Piedmont physiographic
province. According to the map, the site is underlain primarily by the Newark
Supergroup, Chatham Group. The Chatham Group is comprised of
conglomerate, fanglomerate, sandstone, and mudstone. The soils
encountered in this area are Creedmoor-Green Level complex, with 2 to 6
percent slopes. They are poorly to moderately well-drained sandy loams,
clays, and clay loams. However, as the groundwater percolates downward, it
becomes controlled by the subsurface geologic conditions. Thus, the
direction of groundwater movement in the deeper aquifers may not be
consistent with the reflecting topography.

5.2 HYDROGEOLOGY

Groundwater - The 2020 Visual Hydrogeologic Framework – North Carolina
Hydrogeological Database identified three boreholes near the site, but the
site area did not fall within the triangulated area. The closest borehole is the
NCDEQ; 5656_Kelly's Grocery CATLIN Engineers and Scientists
CATLIN Project No. 221050 7 May 2023
Harnett Co. Board of Ed., O 41L borehole (A) which is located approximately
25 miles south-southeast of the subject site. This borehole shows the surficial
aquifer extending approximately 15 feet below the surface. This is underlain
by a confining unit which is underlain by the Black Creek Aquifer which
extends approximately 50 feet below the confining unit.

Slug test analysis conducted in June 2021 resulted in hydraulic conductivities
of 0.02533 feet/day and 0.2839 feet/day at wells MW-2 and MW-3R,
respectively (CATLIN, 2021).

Surface Water – Two surface water bodies were identified within 500 feet of
the site. They are ponds that appear to be used for agricultural activities.

6.0 SITE ASSESSMENT INFORMATION

CATLIN conducted field activities in accordance with the approved TA and pre-
prepared Health and Safety Plan (HASP). Upon arrival at the site, potential hazards
were evaluated before beginning field work and were documented on an electronic
Job Hazard Analysis (JHA) form. The JHA field form is included in Appendix C.
Photographs of the site are included in Appendix B. Well locations and site features
are shown on Figure 3 and well construction details are presented on Table 3.

6.1 AFVR EVENT

CATLIN mobilized to the site on February 28, 2023 to supervise an AFVR
event conducted by EEM. Prior to the event, CATLIN personnel gauged
monitoring wells MW-2 and MW-3R using an electronic groundwater
interface probe and measured depth to water at 16.34 feet BTOC in MW-2
and 12.90 feet BTOC in MW-3R. Light non-aqueous phase liquid (LNAPL;
aka free-product) was not measured.

The AFVR event was conducted for a duration of eight hours utilizing
monitoring wells MW-2 and MW-3R as extraction points. A total of 745
gallons of impacted groundwater were removed from the subsurface. No
measurable LNAPL was observed. A calculated 3.95 pounds of petroleum
vapors were emitted during this event, equivalent to approximately 0.63
gallons of petroleum.

Gauging results are presented in Table 3. Emissions calculations are
included in Appendix D. Field notes by CATLIN personnel and the waste
manifest from EEM are provided in Appendix E.

6.2 GAUGING DATA

Since 2007, the depth to water in the shallow wells has varied between 4.27
feet BTOC (MW-5) and 18.38 feet BTOC (MW-3R). The depth to water in
deep well MW-8D has ranged from 19.20 feet BTOC to 24.41 feet BTOC.
Groundwater flow has varied widely between reporting periods. In 2013,
NCDEQ; 5656_Kelly's Grocery CATLIN Engineers and Scientists
CATLIN Project No. 221050 8 May 2023
groundwater flow appeared to be converging toward the center of the site
(S&ME, 2013) and in 2021, groundwater flow appeared to be diverging
towards the east and west from the source area (CATLIN, 2021).

During the April 2023 event, CATLIN personnel measured depth to water in
nine monitoring wells using an electronic water interface probe. To prevent
cross contamination, the probe and cabling were decontaminated according
to manufacturer’s recommendations between use in each well. Gauging data
were recorded on an electronic groundwater sampling form using a tablet
device. Gauging procedures were performed in general accordance with
North Carolina Department of Environmental and Natural Resources
(NCDENR) and NCDEQ Guidelines, and EPA Region 4 Operating
Procedures.

Depth to water ranged from 8.14 feet BTOC (MW-5) to 17.57 feet BTOC
(MW-7R) in the shallow/Type II wells and was 20.21 feet BTOC in deep/
Type III well MW-8D. Based on groundwater elevations calculated for this
monitoring period, groundwater flow direction is generally towards the east.

Monitoring well gauging results for events conducted by CATLIN are
presented in Table 3. Groundwater elevations are illustrated on Figure 4 and
groundwater sampling forms are provided in Appendix C.

6.3 SAMPLING DATA

Following gauging, the monitoring wells and water supply well were sampled
in general accordance with NCDEQ Guidelines and U.S. EPA Region 4
Operating Procedures. Prior to obtaining representative groundwater
samples, each monitoring well was purged by removing a minimum of three
well volumes using a new, disposable bailer. The water supply well was
purged by allowing the spigot to run for approximately 15 minutes.
Groundwater field parameter data were measured at one-minute intervals
using an In-Situ Aqua TROLL 600 Multiparameter Sonde (Aqua TROLL). The
Aqua TROLL measured specific conductivity, pH, oxidation reduction-
potential (ORP), dissolved oxygen, and temperature, which were recorded
utilizing the VuSitu mobile application (version 1.17.12). Groundwater
parameter data were transferred from the VuSitu mobile application to the
electronic groundwater sampling forms. Copies of the groundwater sampling
forms are available in Appendix C.

After a minimum of three well volumes had been removed from the
monitoring wells (or the well was bailed dry) and the water supply well had
been purged for 15 minutes, groundwater samples were collected from each
well and poured directly into appropriate, laboratory-provided, pre-preserved
glassware, labeled, and placed on ice in an insulated cooler. A laboratory-
provided trip blank was maintained in the cooler for the duration of the
sampling event.

NCDEQ; 5656_Kelly's Grocery CATLIN Engineers and Scientists
CATLIN Project No. 221050 9 May 2023
A field blank was collected by pouring water from a new, sealed gallon of
distilled water directly into laboratory provided glassware. The glassware was
labeled and placed on ice in an insulated cooler.

The groundwater samples, field blank, and laboratory-provided trip blank
were submitted to Con-Test under proper chain-of-custody (COC) protocol
and analyzed per SM 6200B (including EDB, MTBE, and DIPE). The
laboratory analytical data and COC are included in Appendix F.

6.4 SUMMARY OF GROUNDWATER INFORMATION

Historically, the samples from monitoring well MW-1R, MW-2, and MW-3R
have contained several petroleum constituent concentrations above the
2L GWQS. LNAPL has not been detected at this site. Deep monitoring well
MW-8D has historically had all analyte concentrations below the laboratory
detection limits. No petroleum constituents have been detected at
concentrations above their respective GCLs (S&ME, 2020; CATLIN, 2022A).
Historical groundwater sampling results from previous consultants are
provided in Appendix A.

The latest groundwater sampling laboratory results for SM 6200B analysis
are summarized in Table 4. Historical results from sampling conducted by
CATLIN are summarized in Table 5. Monitoring well sample analytical results
are illustrated on Figure 5. A copy of the complete laboratory report and COC
documentation are in Appendix F.

Monitoring Wells

During the April 2023 monitoring event, nine monitoring well groundwater
samples (MW-1R, MW-2, MW-3R, MW-4, MW-5, MW-6, MW-7R, MW-8D,
and MW-9) were collected and submitted for analysis via SM 6200B
(including EDB, MTBE, and DIPE). Laboratory analysis did not detect any
constituents above their respective method detection limits in the samples
from MW-4, MW-5, MW-6, MW-7R, MW-8D, or MW-9. No analyte
concentrations were detected above GCL in any of the monitoring well
samples. Analytical results reported the following constituents at
concentrations above their 2L GWQS in the samples from MW-1R, MW-2,
and MW-3R:
• MW-1R: benzene and naphthalene;
• MW-2: benzene, naphthalene, toluene, 1,2,4-trimethylbenzene, and
total xylenes; and
• MW-3R: benzene, EDB, naphthalene, toluene, 1,2,4-
trimethylbenzene, and total xylenes.

NCDEQ; 5656_Kelly's Grocery CATLIN Engineers and Scientists
CATLIN Project No. 221050 10 May 2023
Water Supply Well

A sample was obtained from before the water treatment system (influent)
connected to water supply well WSW-7. Benzene was reported above the 2L
GWQS in the WSW-7 sample. No other targeted analytes were detected.

Field Blank and Trip Blank

One field blank and one laboratory-provided trip blank sample were collected
for analysis per SM 6200B (including EDB, MTBE, and DIPE). Estimated
concentrations (“J”-flags) of acetone, a common laboratory artifact, were
detected in both samples. No other target analytes were reported.

6.5 EVALUATION OF ASSESSMENT INFORMATION

Extent of Contamination

Several petroleum constituents were detected above their respective
2L GWQS in the samples from MW-1R, MW-2, and MW-3R. However, no
constituents were reported above GCL. A summary of monitoring well
groundwater sample analytical results are illustrated on Figure 5. The
estimated horizontal extents of benzene and naphthalene are illustrated on
Figures 6 and 7, respectively. The horizontal extent of contamination is
generally delineated. Water supply well analytical results are illustrated on
Figure 8.

The highest BTEX concentrations have historically been reported in samples
from MW-1R, MW-2, and MW-3R. The BTEX concentrations in samples
obtained from MW-2 and MW-3R appear to be increasing in relation to the
concentrations historically reported, while those in MW-1R have fluctuated
(CATLIN, 2022B).

Cleanup Levels Achieved

Soil – The available documentation does not provide information on whether
any petroleum-impacted soils were excavated. TPH was historically reported
up to 460 mg/kg (AES, 1991). Soil samples obtained during the December
2021 monitoring event indicated that VOC concentrations are below soil-to-
groundwater maximum soil contaminant concentrations (MSCC).

Groundwater – Groundwater contaminant concentrations are above 2L
GWQS, but below GCL at the site.

LNAPL – LNAPL was not measured during this monitoring period. LNAPL
has historically not been measured at this site.

• Conduct a semi-annual sampling event in October 2023. During the
sampling event, it is recommended to purge the on-site water supply well for
a minimum of 30 minutes and determine if there is an additional sampling
point right before the home treatment system. A sample from the on-site
water supply should also be collected downstream of the treatment system.

8.0 LIMITATIONS

All results in micrograms per liter (µg/L).
BMDL = Below Method Detection Limit (refer to analytical report for a complete list of analytes and detection limits)
Bold results indicate concentrations above 2L GWQS.
GCL = Gross Contaminant Level
2L GWQS = NCAC T15A:02L Groundwater Quality Standards
< = Less than method detection limit
ƚ = The method detection limit is above the 2L GWQS.
J = Detected but below the Reporting Limit (lowest calibration standard); result is an estimated concentration (CLP J-Flag).
L = Laboratory fortified blank/laboratory control sample recovery and duplicate recovery are outside of control limits. Reported value for this compound is likely to be biased on the low side (L-04 Flag).

*QC result is outside of established limits.
Wide recovery limits established for difficult compound.
Wide RPD limits established for difficult compound.
#Data exceeded client recommended or regulatory level
Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the
calculation which have not been rounded.
No results have been blank subtracted unless specified in the case narrative section.
FLAG/QUALIFIER SUMMARY
Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
J
Laboratory fortified blank/laboratory control sample recovery and duplicate recoveries outside of control limits.
Data validation is not affected since all results are "not detected" for associated samples in this batch and bias is
on the high side.
L-02
Laboratory fortified blank/laboratory control sample recovery and duplicate recovery are outside of control limits.
Reported value for this compound is likely to be biased on the low side.
L-04
Elevated reporting limit due to high concentration of target compounds.RL-11
