CATLIN Project No. 221053 2 July 2023
2.0 EXECUTIVE SUMMARY

The Former Annie Bowling Property (Annie Bowling) site is located at 13109 US
Highway 501 (North Roxboro Road), Rougemont, Durham County, North Carolina.
Two underground storage tanks (USTs) were previously operated at the site. One
1,000-gallon gasoline UST and one 560-gallon gasoline UST were removed from
the site in 1997. A petroleum release was discovered during groundwater
investigation activities in the site vicinity.

The purpose of this report is to document the latest groundwater sampling activities
conducted on June 19, 2023. CATLIN Engineers and Scientists (CATLIN)
proceeded to the site to gauge and collect groundwater samples from monitoring
wells MW-01, MW-02, and MW-03. Groundwater was measured at an average of
9.5 feet deep across the site. A sample was collected from water supply well
WSW-51A as well as a surface water sample from Pond 3. All the water samples
were submitted for volatile organic compound (VOC) analysis via Standard Method
(SM) 6200B plus ethylene dibromide (EDB), methyl tert-butyl ether (MTBE), and
diisopropyl ether (DIPE).

Laboratory results did not indicate any dissolved petroleum constituents at
concentrations greater than those established in Title 15A of the North Carolina
Administrative Code, Subchapter 2L, Section .0202 Groundwater Quality Standards
(2L GWQS) in the samples from MW-02 and MW-03. Benzene and naphthalene
were detected in the MW-01 sample at concentrations above 2L GWQS, but below
the Gross Contaminant Levels (GCL).

Laboratory results did not indicate any dissolved petroleum constituents at
concentrations greater than those established in the 2L GWQS in the sample from
WSW-51A. However, MTBE was detected at a concentration which was greater
than the Method Detection Limit (MDL) but significantly less than its 2L GWQS. The
Pond sample contained an estimated concentration (“J”-value) of acetone, which is
a known laboratory relic.

Contaminant concentrations have decreased in the groundwater sample from
monitoring well MW-01 since November 2022 (CATLIN, 2022a).

CATLIN recommends collecting an additional sample from water supply well WSW-
51A to monitor MTBE concentrations and while on-site collect an additional sample
from MW-01 to track contaminant concentrations.

3.0 SCOPE OF SERVICES

The scope of services for this report was performed in general accordance with
CATLIN proposal number 221053.01P, dated May 4, 2023. Services were
authorized by the North Carolina Department of Environmental Quality’s (NCDEQ’s)
Task Authorization (TA) #01, accepted on May 4, 2023, and Contract Number
N70522-A.

NCDEQ; 17956_Former Annie Bowling Property CATLIN Engineers and Scientists
CATLIN Project No. 221053 3 July 2023
The approved scope of services for this Task Authorization included to:
• Prepare and submit an Access Agreement to sample water supply well
WSW-51;
• Determine the use of the water supply well (WSW-51) located across the
street from the subject site;
• Collect groundwater samples from monitoring wells MW-01, MW-02, and
MW-03 as well as water supply well WSW-51;
• Collect a surface water sample from the pond located on the west-adjacent
property (Pond 3);
• Analyze six water samples (three monitoring wells, one water supply well,
one surface water sample, and one field blank) via SM 6200B (plus EDB,
MTBE, and DIPE); and
• Prepare a Monitoring Report summarizing the findings.

Mr. Sean O’Neil (CATLIN Project Manager) met with Mr. Terry (property owner) on
April 28, 2023 to discuss the site and assess conditions around the monitoring wells.
Based on the site visit, and subsequent conversations with Mr. Mark Petermann, a
change order was submitted for reimbursement to the property owner to fix ruts in
the yard from previous site activities.

During sampling field activities, it was discovered that water supply well WSW-51 is
no longer used for drinking water and had been replaced with a well that is identified
as WSW-51A (see Figure 2 for location). Verbal permission was granted to sample
water supply well WSW-51A in lieu of WSW-51. The remaining scope of services
was conducted in general accordance with the approved TA.

4.0 SITE HISTORY AND CHARACTERIZATION

The Annie Bowling site is located at 13109 North Roxboro Road, Rougemont,
Durham County, North Carolina (Figures 1 and 2). Summarized available historical
sampling data are provided in Appendix A. Site photographs are presented in
Appendix B.

4.1 UST OWNER AND OPERATOR INFORMATION

Jasper Hill owned the two USTs historically operated on-site. The tanks were
operated by Mr. Hill for petroleum retail. Mr. Hill is deceased, and the site
was accepted into the North Carolina UST Section Trust Fund Branch State
Lead Program in 1997 (NCDENR, 2008b).

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

4.2 UST INFORMATION

Reportedly, one 1,000-gallon gasoline UST and one 560-gallon gasoline UST
were previously operated on-site. The installation dates are unknown, but the
NCDEQ; 17956_Former Annie Bowling Property CATLIN Engineers and Scientists
CATLIN Project No. 221053 4 July 2023
tanks were operated until October 1975, and removed from the site in
December 1997 (NCDENR, 2008a).

Available UST system information is presented in Table 1 and the
approximate former UST basin location is illustrated on Figure 3.

4.3 CONTAMINANT SOURCE INVENTORY

An on-site release was discovered in 1996 during groundwater investigation
activities. Benzene was detected in nearby water supply wells above its 2L
GWQS (NCDENR, 2008a).

4.4 SITE CHARACTERISTICS

The property is owned by Cooli, LLC and is occupied by an unknown
resident. The parcel is comprised of the residence building, several sheds,
the former store building, a gravel driveway, and grassy areas with scattered
trees. 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 and forested land. The
site is bound by North Roxboro Road (US Highway 501) to the east.
Residences adjoin the property to the north and south, and a large pond is
located to the west.

4.6 RECEPTOR INFORMATION

CATLIN conducted the most recent receptor survey for the Annie Bowling
site in 2021. Pertinent receptor information is summarized below.

The Rougemont Water System is supplied by two community wells located at
12403 North Roxboro Road. Fifty-four water supply wells have been
identified within 1,500 feet of the site. Within 250 feet of the site, two active
non-potable wells were identified. Twelve active potable wells are located
within 1,000 feet from the site. The remaining wells were identified as non-
potable.

Four surface water bodies are located within 1,500 feet of the site. One large
pond is located 362 feet to the west of the site. Three additional ponds are
located between 1,000 and 1,500 feet from the site.

Potential receptors are illustrated on Figure 2 and receptor information
obtained from CATLIN (2021) is shown in Table 2.

CATLIN Project No. 221053 5 July 2023
4.7 PREVIOUS INVESTIGATIONS AND REMEDIAL ACTIVITIES

Investigation activities for the Annie Bowling site were often reported in
conjunction with two other nearby incidents: Rougemont Food Mart #8
(Incident #6280) and Virginia Tackett Property (Incident #13145). All are in
the vicinity of the intersection of North Roxboro Road and Bacon Road and
have potentially contributed to the reported groundwater contamination.

As discussed previously, the release was discovered in 1996 during water
supply well sampling activities by the Durham County Health Department.
The Annie Bowling property was identified by residents as having been a
former convenience store and gas station that had two operated two USTs.
Upon their excavation in December 1997, corrosion was observed on both
tanks and their product lines. Excavated soils were reportedly scanned for
VOCs using an organic vapor analyzer (OVA) and either stockpiled on site or
backfilled in the excavation pit (NCDENR, 2008a).

A leaking UST (LUST) action plan was published in September 2008. Due to
the multiple sources and widespread contamination in the area, it was
determined that the primary actions going forward would be continuing
private water supply well sampling and maintaining the existing point-of-entry
(POE) filtration systems (NCDENR, 2008b).

Multiple water supply well monitoring events have been conducted by various
parties between 1999 and 2008. No monitoring wells were previously
installed on-site. The on-site water supply well (WSW-5) was sampled once
in 2002, where laboratory analysis reported no targeted compounds. This
well was taken out of service by 2004. Through 2004 and 2005, Withers &
Ravenel (W&R) reported that water supply wells WSW-3, WSW-4, WSW-7,
WSW-12, WSW-18, WSW-19, WSW-27, and WSW-28 contained
contaminant concentrations above 2L GWQS (NCDENR, 2008a). Health
Risk Evaluations (HREs) were also continually performed, and their results
reported to the property owners (NCDENR, 2008b).

CATLIN conducted a sampling event in April 2022. Three Type II monitoring
wells (MW-01, MW-02, and MW-03) were installed and a soil sample was
collected from each boring at approximately six to eight below land surface
(BLS). Laboratory analyses revealed no targeted analytes above the
laboratory reporting limits in any soil samples. Several VOCs, semi-VOCs,
and petroleum hydrocarbon compounds were reported above their 2L GWQS
in the MW-01 sample. Only benzene was detected above its 2L GWQS in the
MW-02 sample. No targeted analytes were above GCL (CATLIN, 2022a).

CATLIN conducted a sampling event in November 2022. Groundwater
samples from wells MW-01, MW-02, TMW-04, and TMW-05 were collected.
Laboratory results did not indicate any dissolved petroleum constituents at
concentrations greater than those established in the 2L GWQS in the
samples from MW-02 and TMW-04. Multiple VOCs were detected in the
NCDEQ; 17956_Former Annie Bowling Property CATLIN Engineers and Scientists
CATLIN Project No. 221053 6 July 2023
samples from MW-01 and TMW-05 samples at concentrations above 2L
GWQS, but below their GCL. Additionally, CATLIN conducted slug tests at
the nearby Tackett Residence site (Incident #13145) in monitoring wells
MW-01 and MW-02. Slug test analyses resulted in hydraulic conductivities of
0.00001273 centimeter per second (cm/sec) and 0.000008583 cm/sec at
wells MW-01 and MW-02, respectively. The hydraulic conductivities were
utilized to perform predictive modeling to help determine potential impacts of
the benzene and naphthalene from the Annie Bowling monitoring well
MW-01. Modeling results indicated the non-compliant benzene and
naphthalene plumes should not migrate beyond approximately 50 feet and 15
feet, respectively. The closest receptor (water supply well WSW-4) is located
120 feet cross-gradient. Therefore, the model predicts dissolved
contamination from MW-01 should not impact WSW-4 (CATLIN, 2022b).

A detailed site history prepared by North Carolina Department of
Environmental and Natural Resources (NCDENR, now NCDEQ) and
summarized available historical sampling data from previous consultants are
provided 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 Piedmont physiographic province.

The site is underlain by the felsic metavolcanic rock formation within the
Carolina Slate Belt. According to the 1985 Geologic Map of North Carolina,
metamorphosed dacitic to rhyolitic flows, metavolcanic rock, and
metamudstone crop out in the site area.

Boring logs from the installation of MW-01, MW-02, and MW-03 indicate that
red and yellow silt is present to approximately 10 feet BLS. Orange silt with
black streaks was encountered from approximately 10 to 12 feet BLS. Sand
was observed from 15 to 20 feet BLS (CATLIN, 2021).

From the boring logs of temporary monitoring wells TMW-04 and TMW-05,
tan/brown clay, grading to orange, was present to 20 feet BLS.

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 – Four surface water bodies (ponds) were identified within
1,500 feet of the site. The ponds appear to be for mostly agricultural use.

CATLIN Project No. 221053 7 July 2023

6.0 SITE ASSESSMENT INFORMATION

Field activities included the sampling of three monitoring wells (MW-01, MW-02, and
MW-03), one water supply well (WSW-51A), and one surface water sample from the
pond on the western-adjacent property (Pond #3). These activities were conducted
in general 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 are documented on an electronic Job Hazard Analysis
(JHA) form. The JHA form is included in Appendix C. Photographs from the site visit
are included in Appendix B.

6.1 GROUNDWATER GAUGING DATA

During the June 2023 event, CATLIN personnel measured depth to water in
the monitoring wells using an electronic 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 accordance with
NCDENR and NCDEQ Guidelines, and Environmental Protection Agency
(EPA) Region 4 Operating Procedures.

On June 19, 2023, depth to water ranged from 8.65 feet below top of casing
(BTOC) (MW-01) to 10.94 feet BTOC (MW-03). Based on groundwater
elevations calculated for this gauging event, groundwater flow direction is
towards the west.

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

6.2 GROUNDWATER SAMPLING DATA

Following gauging, the monitoring wells were sampled in general accordance
with NCDENR and NCDEQ Guidelines, and EPA Region 4 Operating
Procedures.

On June 19, 2023, prior to obtaining representative groundwater samples
from monitoring wells MW-01, MW-02, and MW-03, and water supply well
WSW-51A. Each monitoring well was purged by removing a minimum of
three well volumes using a new, disposable bailer and the water supply well
was purged by allowing the spigot to run for approximately 15 minutes.
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
NCDEQ; 17956_Former Annie Bowling Property CATLIN Engineers and Scientists
CATLIN Project No. 221053 8 July 2023
were transferred from the VuSitu mobile application to the electronic
groundwater sampling forms. Copies of the groundwater sampling forms are
available in Appendix C.

All monitoring well groundwater samples were collected from the bailers and
poured directly into appropriate, laboratory-provided, pre-preserved
glassware, labeled, and placed on ice in an insulated cooler. The water
supply well sample was collected directly from the spigot into appropriate,
laboratory-provided, pre-preserved glassware, labeled, and placed on ice in
an insulated cooler.

A surface water sample was collected from Pond 3 at a location that was
approximately downgradient from the monitoring wells. This water sample
was collected with a new disposable bailer and poured directly into the
appropriate laboratory-provided, pre-preserved glassware. The glassware
was labeled and placed on ice in an insulated cooler.

A field blank was collected by pouring water from a new, sealed gallon of
distilled water directly into laboratory-provided, pre-preserved glassware. The
glassware was labeled and placed on ice in an insulated cooler.

The groundwater samples, surface water sample, and field blank sample
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 D.

6.3 SUMMARY OF GROUNDWATER INFORMATION

Historically, benzene has been above 2L GWQS in the sampled water supply
wells in the site vicinity. A detailed site history prepared by NCDENR and
summarized available historical sampling data are provided in Appendix A.

The latest groundwater sampling laboratory results for SM 6200B analysis
are summarized in Table 4. Historical results for events conducted by
CATLIN are included in Tables 5 through 7. Water supply well and Pond
sample analytical results are illustrated on Figure 5. A copy of the complete
laboratory report and COC documentation are in Appendix D.

Monitoring Wells

During the June 2023 monitoring event, samples were collected from three
monitoring wells (MW-01, MW-02, and MW-03) and submitted for analysis
via SM 6200B (including EDB, MTBE, and DIPE). Laboratory analysis did not
detect any constituents above the laboratory method detection limits in the
sample from MW-03. No analyte concentrations were detected above GCL in
any of the monitoring well samples. Estimated concentrations (“J”-values) of
NCDEQ; 17956_Former Annie Bowling Property CATLIN Engineers and Scientists
CATLIN Project No. 221053 9 July 2023
benzene, sec-butylbenzene, and isopropylbenzene were detected in the MW-
02 sample as well as a concentration of MTBE that was below its 2L GWQS.
Analytical results reported benzene and naphthalene at concentrations above
their respective 2L GWQS in the MW-01 sample.

Water Supply Well

A groundwater sample was obtained from water supply well WSW-51A. A
low concentration of MTBE was detected in the WSW-51A sample; however,
it was well below the 2L GWQS. No other targeted analytes were detected.

Surface Water Sample

A surface water sample (Pond) was obtained from Pond 3. An estimated
concentration (“J”-value) of acetone (a common laboratory artifact) was
detected, but it was well below 2L GWQS. No other targeted analytes were
reported.

Field Blank

One field blank sample was submitted for analysis per SM 6200B (including
EDB, MTBE, and DIPE). An estimated concentration (“J”-value) of acetone (a
common laboratory artifact) was detected, but it was well below 2L GWQS.
No other targeted analytes were reported.

6.4 EVALUATION OF ASSESSMENT INFORMATION

Extent of Contamination

Benzene and naphthalene were detected above their respective 2L GWQS in
the groundwater sample from MW-01. However, no constituents were
reported above GCL.

A summary of groundwater sample analytical results is illustrated on Figure
5. The estimated horizontal extent of benzene is shown on Figure 6. The
dissolved phase contaminant plume is horizontally delineated to the north,
south and west, but not the east. The plume is not vertically delineated.

Cleanup Levels Achieved

Soil – Reportedly, soils excavated during UST removal activities were
stockpiled on site and/or backfilled into the excavation pit (NCDENR, 2008a).
The stockpile was disposed of in 1998, containing approximately 8.78 tons of
soil (Mid-Atlantic, 1998). Soil samples obtained in April 2022 indicate that
contaminant concentrations are well below their lowest maximum soil
contaminant concentrations (MSCCs).

NCDEQ; 17956_Former Annie Bowling Property CATLIN Engineers and Scientists
CATLIN Project No. 221053 10 July 2023
Groundwater – Groundwater contaminant concentrations are above 2L
GWQS, but below GCL at the site.

LNAPL – Light non-aqueous phase liquid (LNAPL; aka free product) was not
measured during this monitoring period. LNAPL has not been historically
detected at the site.

7.0 CONCLUSIONS AND RECOMMENDATIONS

Conclusions

Groundwater monitoring findings for this period are summarized below:
• Samples were collected from three monitoring wells (MW-01, MW-02, and
MW-03), one water supply well (WSW-51A), and one surface water body
(Pond 3) and submitted for analysis for VOCs per SM 6200B.
• Benzene and naphthalene were detected above their 2L GWQS, but below
GCL, in the MW-01 sample.
• No contaminant concentrations were above the laboratory reporting limits in
the MW-03 sample.
• The sample from WSW-51A contained a low concentration of MTBE below
the 2L GWQS.
• An estimated concentration (“J”-value) of acetone (a common laboratory
artifact) was detected in the pond sample.
• Groundwater flow direction was calculated to be towards the west.

Recommendations

CATLIN recommends collecting an additional sample from water supply well
WSW-51A to monitor MTBE concentrations and while on-site collect an additional
sample from MW-01 to track contaminant concentrations.

Site Information/Previous Activities
The three sites (Rougemont Food Mart #8, Tackett Residence, and Bowling Property) are located in the vicinity of the Bacon Road/Roxboro Road intersection in Rougemont, North Carolina
(Figure 1 ). Several other potential sources of petroleum contamination (i.e., former gas stations and existing gas stations) have been observed or reported in the vicinity of the site as well.
Groundwater has been impacted by petroleum hydrocarbons in the vicinity of these sites and samples are periodically collected from the surrounding water supply wells. Point-of-entry (POE)
systems have been installed at the Reid Hodnett (WSW-10) and at the Talmage Oakley residences (WSW-19). The Hodnett POE system is a carbon filter located at the kitchen sink, the Oakley
POE system is a Carbonaire system located in a shed near the wellhead of the Oakley WSW. It should be noted that the Oakley WSW/POE system supplies water to four properties. Table 1
presents a summary of the surrounding property owner's information. Figure 2 presents the locations of the properties, WSWs and potential sources of petroleum contamination at the site.
October 1996 On October 4, 1996, GAC treatment system was installed by K&W on the water-supply well that serves Oakley, Rougemont Methodist Church, and church parsonage buildings.
Durham County Environmental Health sampled well for chlorine on October 21, 1996. A prefabricated steel building was also placed over the water-supply well and treatment system and was
equipped with a space heater. A report of these activities was submitted on November 4, 1996.
On October 8, 1996, the Harris' water-supply well was sampled. Benzene concentrations in excess of North Carolina groundwater standards were detected. Results of the sample were sent to
the Harris residence and a report of activities and results was sent to you.
The Rougemont Methodist Church's well was abandoned with cement grout on October 21, 1996. A report of this activity was submitted on November 4, 1996. A copy of the report was also sent
to Durham County Environmental Health and the well abandonment record was sent to the DWQ Groundwater Section.
November 1996 Water-supply well laboratory analytical results were transmitted to the Harris residence on November 8, 1996. Currently evaluating the potential for a community water-supply well
to be installed to serve the Harris and Tackett residen~s and other potential residences in the area. Obtained a tax map, identified area property owners, collected phone numbers, and has
contacted area residents concerning a community well. Currently attempting to arrange a meeting with area residents to discuss the location and other logistics of a community well.
During conversations with property owners, discovered that two additional USTs exist at the former store located adjacent to and to the north of the Harris residence. Currently attempting to
obtain historical information concerning the USTs from the current property owner .
December 1996 Meeting with area residents to discuss the location and other logistics of a community well has been put on hold until determination of responsible party for two USTs discovered
at a former store located adjacent to and to the north of the Harris residence. On December 12, 1996, Mid-Atlantic submitted a letter outlining the history of the USTs and other pertinent
information obtained from interviews with the property owner and others associated with the operation of the USTs.

Single Incident Report
Mr. Phil Orozco informed Mid-Atlantic that the site will be recommended for the federal trust fund. Mid-Atlantic has been requested to wait until the paperwork has been submitted before
preparing a proposal for removal of the two USTs discovered at a former store located adjacent to and to the north of the Harris residence. Bottled water is currently being supplied to the Clayton
and Harris residences.
April1997
After complaints from the property owner that their well water had gotten worse, Mid-Atlantic sampled the Harris water-supply well and analyzed the sample for Standard Method 62300. Benzene
concentrations had increased slightly from the previous sampling event (November 1996). Mid-Atlantic also sampled the Oakley Type Ill water-supply well and tested the water for chlorine. After
chlorine was not detected in the sample, the GAG canister was bypassed (the canister had reportedly become clogged and was reducing water pressure at the house). Mid-Atlantic is supplying
bottled water to the Harris and Clayton residences.
May 1997
Mid-Atlantic sampled the Oakley water-supply system and determined that chlorine was no longer present in the groundwater. K&W Water Conditioning removed the activated carbon unit from
the Oakley water-supply well on May 7 I 1997. Mid-Atlantic submitted a report on May 16, 1997 detailing the removal of the activated carbon system and the results of the Harris water-supply well
sampling conducted in April 1997. Mid-Atlantic is supplying bottled water to the Harris and Clayton residences.

UST Closure --January 1998
GENERAL INFORMATION
Introduction
This report presents the results of environmental services performed at the Bowling property located 13109 Roxboro Road (Highway 501 North) in Durham County, North Carolina (Drawing 1)
.The North Carolina Department of Environment and Natural Resources (NCDENR) contracted with Mid-Atlantic Associates to remove the USTs, observe and document the removal, and prepare
a closure report for the USTs. Mid-Atlantic subcontracted with A & D Environmental and Industrial Services, Inc. (A & D) of High Point, North Carolina to remove and dispose of the USTs. This
work was performed in accordance with the contract number J-6055 dated May 31 I 1996. The scope of work was authorized by issuance of Task Authorization Number 17956-1 dated December
11 1997. This report presents a summary of background information, field activities and procedures, the laboratory test results and our conclusions and recommendations.
Site History
The subject site is currently owned by Ms. Gail Tremmel of Rougemont, North Carolina. The property was formerly owned by Ms. Annie Bowling, Ms. Tremmel's mother. The subject site is
developed with a former gasoline retail station (Drawing 2), but the site's building is currently used by Aircon Refrigeration for commercial purposes. During site work being conducted at the
Tackett residence and Food Mart No.8 sites, which are nearby the subject site, fill ports for two USTs were observed to be present on the north side of the Aircon building. Adjacent property
owners informed Mid-Atlantic personnel that these USTs had not been used in approximately 20 years. It is our understanding that the State could not identify a responsible owner/operator and
the UST removal and site assessment was referred to the State Lead program. Task Authorization Number 17956-1 was issued to Mid-Atlantic to remove the USTs and collect the appropriate
samples for closure purposes.

CLOSURE PROCEDURES
Pre-closure Procedures
Federal Trust Fund
Single Incident Report
Mid-Atlantic and A & 0 mobilized to the site on December 18, 1997 to begin closure activities·. Prior to beginning closure activities, the Fire Marshal of Durham County was contacted to obtain a
permit for removal of the USTs. Mr. Craig Zgilinski, assistant Fire Marshal of Durham County, arrived on site and issued the permit for the UST removals. A copy of the UST Removal Permit is
provided as Appendix A.
Excavation Procedures
A & 0 excavated down to the tops of the USTs to determine the orientations of the USTs and to check the USTs' atmospheres for flammable vapors. The tops of the USTs were located
approximately two feet below land surface (BLS) .The USTs were oriented in an east-west direction and were nested together in one excavation (Drawing 2).
Prior to removing the USTs from the excavation, A & D used a vacuum truck to remove approximately 478 gallons of liquids from the USTs. A copy of A & D's material manifest is included in
Appendix B. Of the 478 gallons, approximately 1,87 gallons originated from the USTs. The remaining 291 gallons consisted of rinsate water used to wash the interiors of the USTs to reduce the
concentration of flammable vapors. Of the 187 gallons that existed within the USTs, Mid-Atlantic estimates that approximately 160 gallons of gasoline and 17 gallons of water existed in the 1 ,000-
gallon capacity UST and 10 gallons of water existed within the 560-gallon UST. These estimates are based on information contained in Southern Pump and Tank Company's "Tank Chart Hand
Book" and liquid level measurements taken from the USTs by RaYmond Marchant of Mid-Atlantic on November 18, 1997.
Following removal of the liquids and rinsate, A & D used a combustible gas meter to check the tank atmosphere for explosive vapors. An LEL reading of zero percent was obtained and Mr.
Zgilinski gave approval to remove the USTs from the excavation. After removal from the excavation, the end of each UST was cut out to prevent the re-accumulation of flammable vapors during
transportation to the disposal facility. Following removal of the USTs, the excavation measured approximately 14 feet long by 12 feet wide by 9 feet deep.
The subsurface product lines were cut off at the edge of the concrete apron to the east of the Aircon building because they could not be removed from beneath the concrete. The vacuum truck
was used to remove any residual product that may have existed in the lines. The ends of the lines were then sealed with a portland cement mixture.
Upon removal of the USTs, Mid-Atlantic visually inspected the tanks for evidence of corrosion or structural failure. One 1/8" hole was observed in the bottom of the east end of the 560-gallon
UST. Although the remainder of the UST shell was rusted and pitted, no other obvious holes were noted. The product line for this UST also showed severe pitting, several 114-inch holes, and an
approximate 1.5-inch long slit which appeared to have resulted from corrosion. Several1/16" to 112" diameter holes were observed in the bottom of the 1 ,000-gallon UST. The USTs were
transported by A & D to D.H. Griffin Wrecking Company in High Point, North Carolina for disposal. A copy of A & D's Tank Disposal Manifest is included in Appendix C.
Excavated Soil
During removal of the USTs, the excavated backfill 'vVSS scanned for the presence of volatile organic compounds with an Organic Vapor Analyzer (OVA) , as discussed in Section 3.1. The
excavated soils consisted of brown to reddish-brown silt. Excavated soils that exhibited elevated OVA readings or obvious petroleum odors were stockpiled on site on plastic sheeting. The
excavated soils that did not exhibit elevated OVA readings or visual or olfactory signs of petroleum contamination were placed back into the excavation as backfill. The remainder of the
excavation was backfilled with ABC stone and compacted with the backhoe bucket in approximately one foot lifts. A four-inch layer of No.57 stone was placed over the disturbed areas to replace
gravel removed during the UST removal activities.

Single Incident Report
Prior to each sampling evei1t, the water supply wells were purged by turning on a spigot and letting the water run at maximum pressure for a minimum of fifteen minutes. Each groundwater
sample was transferred into appropriate laboratory prepared containers, and chilled on ice pending transportation to a North Carolina certified environmental laboratory .All samples were analyzed
for Purgeable Aromatics per EPA Method 62300 to include methyl-tert-butyl ether (MTBE), isopropyl ether (IPE), and ethylene dibromide {EDB).
Fourteen water supply wells 0/VSW2, WSW3, WSW7 , WSW9 through WSWII, WSW13, WSW 14, WSW16, WSW19 through WSW 23) were sampled on December 17,2001. The fourteen wells
were also sampled on March 22, 2002. One well, WSW19, has a POE system; therefore, influent and effluent samples were collected. Carbon filter changes and POE system maintenance is
performed semi-annually (typically December and June). Four properties are connected to WSW19 (Figure 2, Attachment A).
Four water supply 'Nell samples (WSW3, WSW7, WSWIO and WSW19-INF) contained targeted compounds above the 15A NCAC 2l groundwater standard during the December 2001 sampling
event. 1 ,2-Dichloroethane was present in the samples from WSW3 and WSW4 at 1 microgram per liter (-g/l), and WSW19-INF at 2 -g/l, above the 2l standard of 0.38 -g/L However these
concentrations are below the Maximum Contaminant Level (MCL) of 7 -g/L Benzene was present in the WSW10 sample at 3 -g/l, above the 2l standard of 1 -g/l, but below the MCL of 5 -g/l
All other detections during the December 2001 sampling event were below 2l groundwater standards.
Two water supply well samples (WSW3 and WSW7) contained targeted compounds above the ISA NCAC 2L groundwater standard during the March 2002 sampling event. 1 ,2-Dichloroethane
was present in the samples from WSW3 and WSW? at I -giL, above the 2L standard of 0.38 -giL These concentrations are below the MCL of 7 -g/L IPE and MTBE were also present in the
MW3 and MW7 samples, however the concentrations were well below 2L groundwater standards. All other detections during the March 2002 sampling event were below 2L groundwater
standards.
It is recommended to continue semi-annual sampling of the water supply wells because of the detection of targeted compounds in some wells and to monitor the integrity of the clean wells. This
is necessary due to the lack of municipal water in the area. The FOE system located at WSWI9 needs to be maintained semi-annually with routine maintenance and carbon filter changes. The
resident at WSWIO is being furnished with drinking water because of contaminants detected in the well.
October 2002 Sampling Event and Report
Withers & Ravenel sampled WSW-5 (Bowling well) and other water supply wells in 2002. This sampling event was the only time this well was sampled. The well being under the porch was
sampled by collecting a grab sample with a bailer. The analysis showed no reported target petroleum related compounds present.
April 2004 Sampling Event and Report
Withers & Ravenel (W&R) has prepared this letter/report summarizing results of recent water supply well monitoring activities conduded at the referenced sites. During these activities, W&R
personnel: verified existellce of water supply wells in the vicinity of the sites: sampled influent and effluent of two point of entry systems: collected samples from 15 water supply wells located in
the vicinity of the sites. The site locations are presented in Figure 1. ·
Site Information/Previous Activities
The three sites (Rougemont Food Mart #8, Tackett Residence, and Bowling Property) are located in the vicinity of the Bacon Road/Roxboro Road intersection in Rougemont, North Carolina
(Figure 1 ). Groundwater has been impacted by petroleum hydrocarbons in the vicinity of these sites and samples are periodically collected from the surrounding water supply wells. Point-of-entry
(POE) systems have been installed at the Reid Hod nett (WSW-1 0) and at the Talmage Oakley residences (WSW-19) (Figure 1 ). Table 1 presents a summary of the surrounding property
owner's information.
Supply Well Survey Update
W&R personnel were on site on April 13 and April 14, 2004 to verify the water supply well use in the vicinity of the referenced sites. Water supply well use is presented in Figure 2. Observations
made during this survey include: WSWs 4 & 5 have both been taken out of service as WSW sources for their respective residences; WSW-8 has been plumbed to service properties 11 and 13 of
Map 899, Block 2. The Bowling Property {Map 899, Block 2, Property 12) no longer has running water on-site. Table 1 presents property ownership information.
POE System Sampling
W&R personnel were onsite on April13 and April14, 2004 to collect influent and effluent samples from the Reid Hodnett (WSW-10) and Talmage Oakley (WSW-19) POE systems. Prior to
sampling, the wells and lines were purged by opening a tap and allowing them to flow for 20 minutes before sampling. The influent samples from SW-10 and WSW-19 were collected directly from
a tap at the wellheads before the POE system. The effluent samples were collected directly from taps after the POE sy~tems. Figure 2 presents the locations of the WSWs. Table 1 presents

Federal Trust Fund
Single Incident Report
The samples were collected directly into laboratory prepared containers, immediately placed on ice in a cooler and transported under chain of custody to a North Carolina Certified laboratory for
analysis. The samples were analyzed for volatiles by EPA Method 62300.
Based on the laboratory analytical report, no targeted compounds were identified in the influent and effluent samples collected from WSW-10. Analytical results of the influent WSW-19 sample
indicated MTBE, 1 ,2-Dichloropropane, Isopropyl ether and Benzene at concentrations of 140 -g/L, 2.2 -g/L, 1 0-g/L, and 1.8 -g/L, respectively. No targeted compounds were detected in the
effluent sample collected from WSW -19. A copy of the
analytical results is included in Appendix A.
Water Supply Well Sampling
On Apri113 and April 14, 2004, W&R personnel collected groundwater samples from WSWs 2 & 3, WSWs 7 & 8, WSW-11, WSW 13A, 138, & 14, WSW-18, WSW-21 , WSW-23, and WSWs 25
through 28. Figure 2 presents the locations of the WSWs. Table 1 presents property ownership information.
Prior to sampling, W&R purged each well by opening a tap and allowed it to flow for approximately, 15 to 20 minutes. The samples were collected directly into laboratory prepared containers,
immediately placed on ice in a cooler and transported under chain of custody to a North Carolina Certified laboratory for analysis. The samples were analyzed for volatiles by EPA Method 62300.
Based on the laboratory analytical report, results of the WSW-3 sample indicated MTBE at a concentration of 5.4 -g/L. Analytical results of the WSW-7 sample indicated 1,2-Dichloroethal1e at a
concentration of 1.2 -g/L. Analytical results of the WSW-23 sample indicated Trichloroethane only at a concentration of 1.1 -g/L. Analytical results of the WSW-25 sam pie indicated
Bromodichloromethane, Bromoform, Chlorodibromomethane and chloroform at concentrations of 14 -g/L, 13 -g/L, 18-g/L, and 14 -g/L, respectively. No targeted compounds were detected in
the other WSW well samples. A copy of the analytical results is included in Appendix A.
Conclusions and Recommendations
W&R concludes the following:
Three of the WSW's sampled (!/VSW-3, WSW-7 and W SW-19) have been impacted by petroleum hydrocarbons.
Trichloroethane was detected in WSW-23. This is not a compound typically associated with a petroleum release.
Bromodichloromethane, Bromoform, Chlorodibromomethane and chloroform were detected in WSW-25. These compounds are commonly associated with the cleaning of a well.
The POE system on WSW-19 is effectively removing the petroleum contaminants identified.
Based on these conclusions, W&R recommends the following:
Continued WSW sampling;
Continued operation and maintenance of POE systems; Evaluation of impacted wsw well analyses by State Toxicologist.
December 2004 --Risk Ranking completed ---H736D
September 2005 Sampling Event
POE System Sampling
W&R personnel were onsite on September 14, 2005 to collect influent and effluent samples from the Talmage Oakley (WSW-19) Reid Hodnett (WSW-1 0) POE systems. Prior to sampling, the
wells and lines were purged by opening a tap and allowing them to flow for 20 minutes before sampling. The influent samples from WSW-10 and WSW-19 were collected from a tap at the
wellheads before the POE systems. The effluent samples were collected from tap after the POE system. Figure 2 presents the locations of the WSWs. Table 1 presents property ownership
information.
The samples were collected directly into laboratory prepared containers, immediately placed on ice in a cooler and transported under chain of custody to a North Carolina Certified laboratory for
analysis. The samples were analyzed for volatiles by EPA Method 621 OD.
Based on the laboratory analytical report, several targeted compounds were identified in the influent and effluent samples collected from WSW-1 0. The influent and effluent samples from WSW-

10 were similar in contaminant levels. Of the compounds detected in the WSW-1 0 samples, 1 ,2-dichloroethane and benzene were detected above 2L Standards and the benzene concentrations
were also above EPA Drinking Water Standards. Analytical results of the influent WSW-19 sample indicated targeted compounds were identified with benzene above 2L Standards. No targeted
compounds were detected in the effluent sample collected from WSW-19. A copy of the analytical results is included in Appendix A. A summary of the results is included in Table 2.
W&R personnel were onsite again on September 15, 2005 to collect an influent sample from the Oakley POE system to be analyzed for iron. The sample was collected to determine of the
chlorinator located at the effluent of the POE system was necessary due to iron concentrations in the groundwater from the WSW. Mr. Oakley had stated that there were difficulties in regulating
the chlorine levels in the water related to this chlorinator. Prior to sampling, the WSW was purged by opening a tap and allowing it to flow for at least 10 minutes. The sample was collected
directly into laboratory prepared containers, immediately placed on ice in a cooler and transported under chain of custody to a North Carolina Certified laboratory for analysis. The sample was
analyzed for iron by EPA Method 60108.
Based on the analytical report, iron was detected at a concentration of 260 ?g/L. A copy of the analytical results is included in Appendix A.
Water Supply Well Sampling
On September 14 and 15, 2005, W&R personnel collected groundwater samples from WSWs 2, 3, 4, 7, 9, 11, 12, 13A, 136, 14, 15, 16, 18, 21, 23, and WSWs 25 through 31. Figure 2 presents
the locations of the WSWs. WSW-4 at the time of sampling was an inactive WSW. Apparently, this well was previously determined to been impacted by petroleum hydrocarbons and the
residence at this location had been plumbed to and was receiving water from the Tackett Residence WSW-9. As this arrangement had proven to be less than desirable to both parties involved,
WSW-4 was sampled in preparation of it being re-connected to the residence on the property. Table 1 presents property ownership information. WSW-9 reportedly has a POE system, W&R
collected the samples from this well from an effluent location.
Prior to sampling, W&R purged each well by opening a tap and allowing it to flow for approximately 15 to 20 minutes. WSW-4 was purged using a submersible grunfos pump pumping water from
the well for approximately 3 hours prior to sampling. The samples were collected directly into laboratory prepared containers, immediately placed on ice in a cooler and transported under chain of
custody to a North Carolina Certified laboratory for analysis. The samples were analyzed for volatiles by EPA Method 62300.
Based on the laboratory analytical reports, targeted compounds were detected in the samples collected from water supply wells WSW-3, WSW-4, WSW-7, WSW-11, WSW-12, WSW-15, WSW-
16, WSW-18, WSW-27, WSW-28 and WSW-31. Of these water supply wells, the samples collected from WSW-3, WSW-4, WSW -7, WSW-12, WSW-18, WSW-27 and WSW-28 had 2L
Standards violations. Jt should be noted that the compounds detected in WSW-12 and WSW-18 are commonly associated with well disinfection and are not likely related to petroleum releases in
the area. results of the WSW-3 sample indicated 1,2-Dichloroethane at a concentration of 1.2 ?g/L Analytical results of the WSW-7 sample indicated 1,2-Dichloroethane at a concentration of
1.4 ?g/L. Analytical results of the WSW-25 sample indicated Bromodichloromethane, Bromoform, Chlorodibromomethane and chloroform at concentrations of 3.6 ?g/L, 4.5 ?giL, 4.8?g/L, and 4.2
?g/L, respectively. No targeted compounds were detected in the other WSW well samples. A copy of the analytical results is included in Appendix A.
W&R personnel were onsite again on October 5, 2005 to res ample WSW-4 following the reconnection of this well to the residence at this property. Prior to sampling, W&R purged the well by
opening a tap and allowing it to flow for approximately 15 to 20 minutes. The samples were collected directly into laboratory prepared containers, immediately placed on ice in a cooler and
transported under chain of custody to a North Carolina Certified laboratory for analysis. The samples were analyzed for volatiles by EPA Method 62300.
Based on the laboratory analytical report, targeted compounds were detected in the samples collected from water supply well WSW-4 at concentrations above 2L Standards. The contaminant
levels were similar in magnitude as indicated in the original sampling event conducted in September. Trichloroethane indicated in this sample was not detected in the September sample. This
may be related to the solvent cement required during plumbing of the well to the house.
Conclusions and Recommendations
W&R concludes the following:
Several WSWs located in the vicinity of the sites have been impacted by petroleum hydrocarbons.
The compounds identified in WSW-12 and WSW~ 18 are commonly associated with the disinfection of a well or chlorination of the water.
The POE systems on WSW-9 and WSW-19 are effectively removing the petroleum contaminants identified.
The POE system on WSW-10 needs replacement.
Based on these conclusions, W&R recommends the following:
Continued WSW sampling.
Continued operation and maintenance of POE systems.
Evaluation of impacted WSW well analyses by State Toxicologist.

Dear Mr. Petermann:
Withers & Ravenel (W&R) has prepared this letter/report summarizing results of recent water supply well (WSW) monitoring activities conducted at the referenced sites. During these activities,
W&R personnel sampled the influent and effluent of 1 point-of-entry (POE) systems and collected samples from 22 additional WSWs located in the vicinity of the sites. A site location map is
presented in Figure 1.
Site Information/Previous Activities
The three sites (Rougemont Food Mart #8, Tackett Residence, and Bowling Property) are located in the vicinity of the Bacon Road/Roxboro Road intersection in Rougemont, North Carolina
(Figure 1 ). Several other potential sources of petroleum contamination (i.e., former gas stations and existing gas stations) have been observed or reported in the vicinity of the site as well.
Groundwater has been impacted by petroleum hydrocarbons in the vicinity of these sites and samples are periodically collected from the surrounding water supply wells. Point-of-entry (POE)
systems currently exists at the Talmage Oakley residence (WSW-19). The Oakley POE system is a Carbona ire system located in a shed near the wellhead of the Oakley WSW. It should be
noted that the Oakley WSW/POE system supplies water to four properties. Historic analytical results of samples collected from WSW~ have indicated impact by targeted compounds and
therefore this property has been provided bottled water for consumption. Table 1 lists properties and water supply wells in the vicinity of the site. Figure 2 presents the locations of the properties,
WSWs and potential sources of petroleum contamination at the site.
POE System Sampling
W&R personnel were onsite March 6, 2008 to collect influent and effluent samples from the Talmage Oakley (WSW-19) filtration system. Prior to sampling, the well and lines were purged by
opening a tap and allowing them to flow for 15 minutes before sampling. The influent sample from the well was collected from a tap at the wellhead before the POE/filter system. The effluent
sample was collected from a tap after the POE/filter system. Figure 2 presents the locations of the WSW. Table 1 presents property ownership information.
The samples were collected directly into laboratory prepared containers, immediately placed on ice in a cooler and transported under chain of custody to a North Carolina Certified laboratory for.
analysis. The samples were analyzed for volatiles by EPA Method 62100.
Based upon the laboratory analytical report, the sample containers were mislabeled and the influent for MW-19 was placed in the containers labeled MW-15 and the sample from MW-15 was
placed in the containers for MW-191nfluent. Due to this, W&R personnel returned to the site on March 20, 2008 to resample WSW-15 and WSW-191 nfluentiEffluent.
Based on the laboratory analytical report for the March 2oth samples, targeted compounds were identified in the influent samples collected from WSW-19 sample at concentrations above 2L
Standards. No targeted compounds were detected in the effluent sample collected from WSW-19. A copy of the analytical results is included in Appendix A. A summary of the analytical results is
included in Table 2.
Water Supply Well Sampling
On March 6, 2008 W&R personnel collected groundwater samples from WSWs 2, 3, 4, 7,9, 10,11, 12, 13A, 138,14, 15,16,18,21,23, WSWs 25 through 29, and 31. Table 1 and Table 2 present
property ownership and WSW information. Figure 2 presents the locations of the WSWs.
Prior to sampling, W&R purged each well by opening a tap and allowing it to flow for approximately 15 minutes. The samples were collected directly into laboratory prepared containers,
immediately placed on ice in a cooler and transported under chain of custody to a North Carolina Certified laboratory for analysis. The samples were analyzed for volatiles by EPA Method 62100.
Based upon the laboratory analytical report, the sample containers were mislabeled and the influent for MW-19 was placed in the containers labeled MW-15 and the sample from MW-15 was
placed in the containers for MW-19 Influent. Due to this, W&R personnel returned to the site on March 20, 2008 to resample WSW-15 and WSW-191nfluenVEffluent.
Based on the laboratory analytical reports, 1 ,2-dichloroethane (1.4 ,ug/L) and MTBE (4.8 ,ug/L) were detected in the sample collected from water supply well WSW-7 only. The concentration of 1
,2-dichloroethane exceeds its 2L Standard of 0.038 ,ug/L A summary of the results is included in Table 2. A copy of the analytical results is included in Appendix A.

Single Incident Report
Analytical results indicate that WSW 7 and WSW-19 are be impacted by targeted petroleum hydrocarbons at concentrations above 2L Standards.
The POE system on WSW-19 is effectively removing the petroleum contaminants identified.
Continued WSW monitoring.
Continued operation and maintenance of POE system. Property owner notification of impacted WSW results.
Evaluation of the WSW analytical results by the State Toxicologist to determine proper use of these water supply sources.
July 30, 2008-A series of telephone conversations held with Ms. Tremmel to discuss to discuss the site property situation, Tackett's not agreeable to connect Bowling/Tremmel property to the
POE system on the Tackett property,her son wants the property. Will State install another well and or POE system on the well if the well is contaminated .. This was discussed internally, in a
return call to Ms. Tremmel, not Dept policy to install wells or install POE systems on wells if the owners already know there is contamination incident and they install a well in a know
contamination area. MAP encouraged Ms. Tremmel to speak to management, including grover Nicholson.
This site also needs a new septic system installed. That's a county function. That could affect where a new well could be installed.

*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
Elevated reporting limit due to high concentration of target compounds.RL-11
