2.0 EXECUTIVE SUMMARY
The Mann Store site is located at 7070 NC Highway 87 North, Pittsboro, Chatham
County, North Carolina. Four underground storage tanks (USTs) were previously
operated at the site. One 2,000-gallon gasoline, one 550-gallon kerosene, and two 1,000-gallon gasoline USTs were removed from the site in 1990. A petroleum release was discovered during tank closure activities.
The purpose of this report is to document the latest remediation efforts and
groundwater sampling event. On January 23 and 27, 2023, CATLIN Engineers and Scientists (CATLIN) personnel supervised the set-up and shut-down of a mobile multi-phase extraction (MMPE) event conducted by Advanced Environmental Services, Inc. (AES). A total of 2,526 gallons of impacted groundwater were
removed from the subsurface and 53.41 pounds of petroleum vapors (equivalent to
8.68 gallons of petroleum) were emitted. CATLIN returned to the site on February 28, 2023, to conduct groundwater gauging and sampling at the site. Depth to groundwater was measured at approximately 21
feet deep across the site. Groundwater samples were collected from four monitoring
wells (MW-1 through MW-04) and one water supply well (WSW-8) on the south-adjacent property. 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), and diisopropyl ether (DIPE).

Laboratory results indicated multiple VOCs detected in the MW-1, MW-02, and MW-04 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).
Multiple targeted analytes were detected in the WSW-8 sample above the laboratory
method detection and/or reporting limits, including benzene above its 2L GWQS and the maximum contaminant level of 5 micrograms per liter (µg/L). Contaminant concentrations appear to have generally decreased in the sample from
monitoring well MW-1 and MW-04 since the previous sampling event (September 2022), while those in MW-2 have fluctuated. However, concentrations have increased in samples from WSW-8 (CATLIN, 2022A). CATLIN recommends to:
• Determine the feasibility of relocating WSW-8 to another portion of the property;
• Evaluate permeable reactive barriers to prevent migration of contaminant
concentrations off-site; and
• Conduct a semi-annual sampling event in August 2023.

3.0 SCOPE OF SERVICES The scope of services for this report was performed in general accordance with
CATLIN proposal number 221042.04P, dated December 20, 2022. Services were
authorized by the North Carolina Department of Environmental Quality’s (NCDEQ’s) Task Authorization (TA) #04, accepted on December 20, 2022, and Contract Number N122019D.
The approved scope of services for this Task Authorization included to:
• Update the site-specific Health and Safety Plan (HASP) for MMPE activities;
• Coordinate and oversee a MMPE event;
• Approximately 30 days after the event, collect groundwater samples from four monitoring wells (MW-1 through MW-04) and one water supply well (WSW-8);
• Analyze seven water samples (four monitoring wells, one water supply well,
one equipment rinsate blank, and one trip blank) per SM 6200B (plus EDB, MTBE, and DIPE); and
• Prepare a monitoring report documenting the findings.
The scope of services was conducted in general accordance with the approved TA. 4.0 SITE HISTORY AND CHARACTERIZATION
The Mann Store site is located at 7070 NC Highway 87 North, Pittsboro, Chatham County, North Carolina (Figures 1 and 2). Summarized available historical sampling and gauging data are provided in Appendix A. Site photographs are presented in Appendix B. 4.1 UST OWNER AND OPERATOR INFORMATION Glen and Muriel Mann owned the four USTs historically operated on-site, which were used for petroleum retail. The Manns denied responsibility for the release and the site was accepted into the Federal Leaking Underground
Storage Tank Trust Fund in 1992 (NCDENR, 1992). Later investigations revealed that both Mr. and Mrs. Mann are now deceased, and the site was accepted into the North Carolina UST Section Trust Fund Branch State Lead Program in 2004 (S&ME, 2019; NCDENR, 2004).
Available information regarding UST owners and operators is presented on Table 1. 4.2 UST AND AST INFORMATION
One 2,000-gallon gasoline, one 550-gallon kerosene, and two 1,000-gallon gasoline USTs were previously operated on-site. Information on the installation dates is unavailable, but the tanks were reportedly operated until 1966. The tanks were removed from the site in December 1990 (S&ME, 2019; NCDENR, 2008).
NCDEQ; 6281_Mann Store CATLIN Engineers and Scientists
CATLIN Project No. 221042 4 April 2023
One propane aboveground storage tank (AST) is located behind the site building; construction, installation, and operational details are unknown.
Available UST system information is presented in Table 1 and the
approximate locations of the former UST basin, former pump island, and AST are illustrated on Figure 3. 4.3 CONTAMINANT SOURCE INVENTORY

An on-site release was discovered in 1990 during UST removal activities. Soil sample analytical results revealed total petroleum hydrocarbons (TPH) above State Action Levels (NCDENR, 1991).
4.4 SITE CHARACTERISTICS
The property is owned by the Vaughn Living Trust and the property is currently vacant. The parcel is comprised of the store building, three garages, a paved parking pad, a large shipping/storage container, and a shed. Grassy
areas and forested land are located around and behind the site building. Site
photographs are presented in Appendix B. 4.5 OWNERS AND OCCUPANTS OF ADJOINING/NEARBY PROPERTIES AND LAND USE

Properties in the site vicinity are mostly residences, agricultural land, and forested land. The site is located at the intersection of NC Highway 87 North and Castle Rock Farm Road. The site is bound by NC Highway 87 to the west and forested land to the north and east. A residence adjoins the
property to the south.
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 Mann Store site was conducted in 2019 by S&ME, Inc. (S&ME). According to previous reports, municipal water is not available to the site
vicinity. One inactive and eight active potable water supply wells have been identified within 1,500 feet of the site. There are three wells located within 500 feet of the site, including one located approximately 50 feet to the south (WSW-8).
Three surface water bodies are located within 1,500 feet of the site. A farm pond is located 525 feet to the northwest. The Long Branch Stream and an intermittent stream are located 1,450 feet south and 1,000 feet northeast of the site, respectively.
NCDEQ; 6281_Mann Store CATLIN Engineers and Scientists
CATLIN Project No. 221042 5 April 2023
Potential receptors are illustrated on Figure 2 and receptor information obtained from S&ME (2019) is shown on Table 2.
4.7 PREVIOUS INVESTIGATIONS AND REMEDIAL ACTIVITIES
The release was discovered in 1990 during UST closure activities. Soil samples collected during tank removal reportedly contained TPH concentrations up to 853 parts per million (ppm) (NCDENR, 1991). A film of
light non-aqueous phase liquid (LNAPL; aka free product) was observed on
top of the groundwater in the bottom of the excavation pit. Approximately 217 cubic yards of contaminated soil were removed from the site (S&ME, 2019). The water supply wells located on neighboring properties were periodically
sampled between 1991 and 2010. Of particular concern was the water supply
well on the adjoining property, located approximately 50 feet south from the source area (currently designated as WSW-8). Since 1991, it has contained multiple gasoline constituents above the reporting limit and benzene was detected above the 2L GWQS from 1998 to 2018. When the property was
occupied, bottled water was provided to the residents. Other water supply
wells (WSW-1, WSW-4, WSW-5, and WSW-7) were sampled between 2004 and 2010, but there were no detections above the laboratory limits (S&ME, 2019). However, in 2018 a sample from WSW-1 contained benzene above its 2L GWQS as well as low detections of multiple other targeted analytes
(NCDEQ, 2018).
S&ME conducted a Phase I Limited Site Assessment (LSA) in 2019. Site activities included the installation of a permanent monitoring well (MW-1), an updated receptor survey, and soil and groundwater sampling. No targeted
analytes were detected in the soil sample collected during monitoring well
installation. However, laboratory analytical results of the groundwater sample from MW-1 revealed benzene, MTBE, and naphthalene above their 2L GWQS and VPH carbon fraction chains above regulatory limits. Water supply well WSW-8 was also sampled and once again contained benzene above its
2L GWQS, as well as other targeted analytes above the method detection
limit (S&ME, 2019). CATLIN sampled monitoring well MW-1 in 2021. Benzene, MTBE, and naphthalene were reported above their 2L GWQS; however, the contaminant
concentrations had decreased since the 2019 sampling event (CATLIN, 2021; S&ME, 2019). In May 2022, CATLIN oversaw the installation of three additional monitoring wells (MW-02 through MW-04) to approximately 40 feet. These wells were
then sampled along with the south-adjacent water supply well (WSW-8). Laboratory results indicated the presence of multiple VOCs detected in the MW-1, MW-02, and MW-04 samples at concentrations greater than those established in the 2L GWQS, but below the GCL. The sample from MW-04 also contained one carbon fraction chain (C9-C10 aromatics) above their 2L
NCDEQ; 6281_Mann Store CATLIN Engineers and Scientists
CATLIN Project No. 221042 6 April 2023
GWQS. Two targeted analytes were detected in the WSW-8 sample (DIPE and MTBE), but both were below their 2L GWQS. Lead was detected above its 2L GWQS in the samples from MW-02 and MW-04; however, the
groundwater in the wells was highly turbid, and these concentrations may not
have been reflective of lead concentrations in the groundwater beneath the site (CATLIN, 2022A). CATLIN conducted a groundwater sampling event in September 2022.
Monitoring wells MW-1 through MW-04 and water supply well WSW-8 were
sampled. Multiple VOCs were reported in the MW-1, MW-02, and MW-04 samples at concentrations above 2L GWQS but below GCL. Low concentrations of DIPE and MTBE were again reported in the WSW-8 sample but were below their respective 2L GWQS. Contaminant
concentrations in monitoring well MW-1 had decreased since the May 2022
sampling event, while those in MW-02 and MW-04 increased (CATLIN, 2022B). Summarized available historical sampling and gauging data from previous
consultants are provided in Appendix A and the historical groundwater
collected by CATLIN is presented in Tables 5 and 6. 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 Piedmont physiographic province.
The site is underlain by the metamudstone and meta-argillite formation within the Carolina Slate Belt. According to the 1985 Geologic Map of North Carolina, metasandstone, metaconglomerate, and metavolcanic rock crop out in the site area.
Boring logs from the May 2022 event indicate that silty clay is present to approximately 10 feet below land surface (BLS). Weathered rock fragments were encountered at further depths ranging from 18 to 44 feet BLS (CATLIN, 2022A).
5.2 HYDROGEOLOGY
Groundwater - The 2020 Visual Hydrogeologic Framework (VHF) – North Carolina Hydrogeological Database did not identify sufficient boreholes near
the site to draw a cross-section.

Surface Water – Three surface water bodies were identified within 1,500 feet of the site: a farm pond, intermittent stream, and Long Branch Stream.

CATLIN Project No. 221042 7 April 2023
6.0 SITE ASSESSMENT INFORMATION CATLIN conducted field activities in general accordance with the approved TA and
pre-prepared HASP. Upon arrival at the site, potential hazards were evaluated
before beginning field work and are documented on an electronic Job Hazard Analysis (JHA) form. The JHA form is included in Appendix C. Photographs from the site visits are included in Appendix B.
CATLIN personnel gauged and collected groundwater samples for laboratory
analysis of VOCs per SM 6200B from four monitoring wells (MW-1, MW-02, MW-03, and MW-04) and one water supply well (WSW-8). Well locations and site features are shown on Figure 3 and well construction details are presented in Table 3.
6.1 MMPE EVENT CATLIN mobilized to the site on January 23 and 27, 2023 to supervise the set-up and shut-down of a MMPE event conducted by AES. The MMPE event was conducted for a duration of 96 hours, ending on January 27, 2023.
Monitoring wells MW-1, MW-02, and MW-04 were utilized as extraction
points. Prior to the event, the monitoring wells were gauged and the depths to water were 21.98 feet below top of casing (BTOC) (MW-1), 22.24 feet BTOC (MW-02), and 21.20 feet BTOC (MW-04). LNAPL was not encountered.

A total of 2,526 gallons of impacted groundwater were removed from the subsurface. The vacuum at the recovery pump ranged from 16.0 to 20.0 inches of mercury and stabilized at approximately 18.0 inches of mercury. Airflow rates ranged from 2,800 to 3,600 feet per minute and stabilized at
approximately 3,300 feet per minute. The system temperature ranged from
70 to 112 degrees Fahrenheit and humidity maintained and stabilized at 99 percent. Field gauged VOCs decreased from 8,000 ppm to 600 ppm throughout the event. A calculated 53.41 pounds of petroleum vapors were emitted during this event, equivalent to approximately 8.68 gallons of
petroleum. The average rate of fluid recovery was 26.31 gallons per hour.
The MMPE report from AES, including the material manifest and emissions calculations, is included in Appendix D.
6.2 GAUGING DATA
Historically, depth to water in the monitoring wells has ranged from 19.03 feet
BTOC (MW-1) to 34.43 feet BTOC (MW-1). Groundwater was previously illustrated to be toward the south (CATLIN, 2022B; S&ME, 2019). During the February 2023 event, CATLIN personnel measured depth to water
in four monitoring wells (MW-1 through MW-04) using a water level indicator. 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
NCDEQ; 6281_Mann Store CATLIN Engineers and Scientists
CATLIN Project No. 221042 8 April 2023
accordance with North Carolina Department of Environmental and Natural Resources (NCDENR) and NCDEQ Guidelines, and Environmental Protection Agency (EPA) Region 4 Operating Procedures.

Depth to water ranged from 19.93 feet BTOC (MW-04) to 21.46 feet BTOC (MW-02) in the shallow/Type II wells. LNAPL was not encountered in any of the wells. The depth to water measured in MW-1 was above its screened interval. Based on groundwater elevations calculated for this monitoring
period, groundwater flow direction is generally towards the south (toward
WSW-8). 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 were sampled in general accordance
with NCDENR and NCDEQ Guidelines, and EPA Region 4 Operating
Procedures. Prior to obtaining representative groundwater samples, each monitoring well was purged by removing a minimum of three well volumes (or until the well was purged dry) using a new, disposable bailer. Monitoring well groundwater field parameter data were measured at one-minute intervals
using an In-Situ Aqua TROLL 600 Multiparameter Sonde (Aqua TROLL).
Conductivity, pH, oxidation reduction potential (ORP), dissolved oxygen, and temperature measurements 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 were removed (or the well was bailed dry), groundwater samples were collected from the wells and poured into
appropriate, laboratory-provided, pre-preserved glassware, labeled, and placed on ice in an insulated cooler. A laboratory-provided trip blank accompanied the samples for the duration of the site activities. The water supply well was sampled in general accordance with NCDEQ
Guidelines and U.S. EPA Region 4 Operating Procedures. Prior to obtaining a representative groundwater sample, the water supply well was allowed to run for 15 minutes. After the water supply well was purged, a sample was collected from a spigot
located at the water supply well directly into appropriate, laboratory-provided, pre-preserved glassware, labeled, and placed on ice in an insulated cooler. To verify that sampling equipment was decontaminated sufficiently between wells, an equipment rinsate blank was collected from the electronic water
NCDEQ; 6281_Mann Store CATLIN Engineers and Scientists
CATLIN Project No. 221042 9 April 2023
interface probe. Clean distilled water was allowed to cascade down the electronic probe and into appropriate laboratory-provided, pre-preserved glassware. The glassware was labeled and placed on ice in an insulated
cooler.
The groundwater samples, equipment rinsate blank, and laboratory-provided trip blank were submitted to Con-Test Analytical Laboratory (Certification NC 652 and NC-DW 25703) in East Longmeadow, Massachusetts, 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 E. 6.4 SUMMARY OF GROUNDWATER INFORMATION

During previous sampling events, groundwater samples collected from monitoring well MW-1 have contained benzene, MTBE, and naphthalene concentrations above their 2L GWQS. During the LSA conducted by S&ME (2019), the sample from water supply well WSW-8 contained benzene above
its 2L GWQS. However, benzene was reported below the detection limit in
subsequent sampling events in May and September 2022. No petroleum constituents have been detected at concentrations above GCL. Summarized available historical sampling and gauging data from previous consultants are provided in Appendix A.
The latest groundwater sampling laboratory results for SM 6200B are summarized in Table 4. Historical results from events conducted by CATLIN are in Tables 5 and 6. Monitoring well and water supply well sample analytical results are illustrated on Figure 5. A copy of the complete
laboratory report and COC documentation are in Appendix E.

Monitoring Wells During the February 2023 monitoring event, four monitoring well groundwater
samples (MW-1, MW-02, MW-03, and MW-04) were collected and submitted for analysis via SM 6200B (including EDB, MTBE, and DIPE). Laboratory analysis did not detect any constituents above 2L GWQS in the sample from MW-03. No analyte concentrations were detected above the GCL in any of the monitoring well samples. Analytical results reported the following
constituents at concentrations above their 2L GWQS in samples MW-1, MW-02, and MW-04:
• MW-1 and MW-02: benzene and MTBE; and
• MW-04: benzene, naphthalene, and n-propylbenzene.
Water Supply Well A groundwater sample was obtained from water supply well WSW-8.
Benzene was reported at a concentration of 13 µg/L, above the 2L GWQS of 1 µg/L and MCL of 5 µg/L . Multiple other targeted analytes were reported at
NCDEQ; 6281_Mann Store CATLIN Engineers and Scientists
CATLIN Project No. 221042 10 April 2023
low or estimated concentrations (“J”-values), but below their respective 2L GWQS.
Analytical results reported the following constituents at concentrations above
the laboratory method detection limit, but below their respective 2L GWQS: sec-butylbenzene (J), DIPE, isopropylbenzene, MTBE, naphthalene (J), n-propylbenzene, toluene (J), 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene (J), and m+p xylene.

Equipment Rinsate Blank and Trip Blank One equipment rinsate blank (EQ. Rinse) and one laboratory-provided trip blank were submitted for analysis per SM 6200B (including EDB, MTBE, and
DIPE). Estimated concentrations (“J”-values) of acetone (a common
laboratory artifact) were reported in both samples, and an estimated concentration of chloroform was reported in the trip blank. No other targeted analytes were detected in either sample.
6.5 EVALUATION OF ASSESSMENT INFORMATION

Extent of Contamination Several petroleum constituents were detected above their respective 2L
GWQS in samples from MW-01, MW-02, and MW-04. However, no
constituents were reported above GCL. A summary of monitoring well and water supply well groundwater sample analytical results are illustrated on Figure 5. The dissolved phase contaminant plume is only horizontally delineated to the east and is not vertically delineated.

The contaminant concentrations in samples obtained from MW-1 and MW-04 appear to be generally decreasing in relation to the concentrations historically reported, while those in MW-02 have fluctuated. However, they have increased in the sample from WSW-8 since the previous monitoring event in
September 2022, including benzene at a concentration above 2L GWQS and
MCL where previously it had been below the method detection limit (S&ME, 2019; CATLIN, 2022B). Cleanup Levels Achieved

Soil – To date, approximately 217 cubic yards of impacted soil have been removed from the site (December 1990). At that time, laboratory results for the soil samples reported levels of TPH concentrations above regulatory limits. S&ME reportedly advanced four soil borings and collected one soil
sample in July 1998, although the location of this soil sample was not indicated. At that time, the soil sample results indicated TPH concentrations above the regulatory limit. During performance of the LSA in 2019, a soil sample was collected during installation of MW-1. Laboratory results did not indicate the presence of VOCs above detection limits. Soil samples obtained
NCDEQ; 6281_Mann Store CATLIN Engineers and Scientists
CATLIN Project No. 221042 11 April 2023
in 2021 (in the general vicinity of the MW-3 location) indicated that VOC concentrations were below detection limits (S&ME, 2019; CATLIN, 2021).
Groundwater – Groundwater contaminant concentrations are above 2L
GWQS, but below GCL at the site. The sample obtained from WSW-8 during this event contained multiple targeted analytes above their method detection limits and benzene above its 2L GWQS and MCL.
LNAPL – LNAPL has not been reported at the site since initial excavation in
1990. 7.0 CONCLUSIONS AND RECOMMENDATIONS
Conclusions
Groundwater monitoring findings for this period are summarized below:
• A MMPE event was conducted from January 23 to 27, 2023 utilizing MW-1,
MW-02, and MW-04 as extraction points. A total of 2,526 gallons of impacted
groundwater and 53.41 pounds (8.68 equivalent gallons) of petroleum vapors were removed.
• Four monitoring wells (MW-1, MW-02, MW-03, and MW-04) and one water
supply well (WSW-8) were sampled and analyzed per SM 6200B (plus EDB, MTBE, and DIPE);
• No targeted analytes were above 2L GWQS in the sample from MW-03.
• Several contaminant concentrations were above 2L GWQS in the samples
from MW-1, MW-02, and MW-04; however, all were below GCL.
• Multiple targeted analytes were detected in the WSW-8 sample, including benzene above both its 2L GWQS and MCL. During previous events,
benzene has been below the method detection limit in samples from WSW-8.
• Groundwater flow was calculated to be generally toward the south (towards WSW-8) during this monitoring period.
Recommendations
CATLIN recommends to:
• Determine the feasibility of relocating WSW-8 to another portion of the
property;
• Evaluate permeable reactive barriers to prevent migration of contaminant concentrations off-site; and
• Conduct a semi-annual sampling event in August 2023.

Description of Event:
The MMPE event ran from 12:05 January 23, through 12:05 January 27, 2023. The MMPE
system was active for 96.0 hours. During the event vacuum at the recovery pump ranged from
16.0 to 20.0 inches of mercury (hg) and stabilized at approximately 18.0 inches of mercury.
Airflow rates ranged from 2,800 to 3,600 feet per minute and stabilized at 3,300 feet per minute.
System temperature ranged from 70 – 112 degrees (F) and humidity maintained 99 percent. Field
gauged volatile organic compounds (VOC’s) decreased from 8,000 parts per-million (PPM) to
600 (PPM) throughout the event.

Groundwater / Product Mix Recovered:
During the event, a total of 2,526 gallons of product/water mix were removed from the site and
properly disposed at a certified North Carolina disposal facility. No free product was recovered
as liquid. Total fluids recovered, was measured based on stick readings conducted during and
following the event. Based on 96.0 hours of operation and a total of 2,526 gallons recovered, the
average groundwater recovery rate was calculated to be approximately 26.31 gallons per hour.

Events Results:
Based on mass-removal calculations 53.41 pounds or 8.68 gallons of VOC’s were removed as
vapor. Using Dwyer Magnehelic gauges, vacuum influence (inches of water) was measured at
monitoring point MW-03. Measurable vacuum influence was observed in MW-3 up to 5.00+
inches of water. Draw-down was observed in MW-3 at 4.43 feet. Following the event, no free
product was identified in any well.
