2.0 EXECUTIVE SUMMARY

ATC Associates of North Carolina, P.C. (ATC) has completed a Site Check Report for the
Piedmont Property. This report documents the advancement of one soil boring, the installation of
one temporary monitoring well, and the subsequent soil and groundwater sampling. The work is
being performed based on a October 17, 2019 Task Authorization (TA-02) by the Trust Fund
Branch of the Underground Storage Tank (UST) Section, Division of Waste Management, North
Carolina Department of Environmental Quality (NCDEQ). The work was performed as part of
State Lead Contract #N17004 between NCDEQ and ATC.

The Piedmont Property site is located on the southeast corner of the intersection of Outer Loop
Road and US Highway 15 on the north side of Oxford, Granville County, North Carolina. The
parcel on which the former gas station was located (Piedmont Property) was acquired by the
North Carolina Department of Transportation (NCDOT) in 1987 as part of the right-of-way for
the intersection of US Highway 15 and US Highway 158. At the time of acquisition, the
property was operating as a service station with gasoline sales. The property included three
USTs of unspecified sizes and contents, a water supply well, and several structures. In
November of 1987, the NCDOT removed the USTs, abandoned the water supply well, and
demolished all of the structures on the parcel.

On January 14, 2020, ATC personnel mobilized to the site to supervise the advancement of one soil
boring and the installation of one temporary monitoring well (TW-1) in the location of the former
UST basin. ATC collected soil and groundwater samples from this boring. In addition, permission
was obtained from the southeast-adjacent property owner to collect a groundwater sample from a
monitoring well that was installed in 1993 as part of due diligence activities. This monitoring well
(Triangle Well) was also sampled.

Soil and groundwater samples were collected from soil boring Temp Well-1. Soil analytical results
did not indicate the presence of compounds above the Soil-to-Groundwater Maximum Soil
Contaminant Concentrations (MSCCs). The groundwater sample collected from Temp Well-1
indicated benzene above the North Carolina Groundwater Quality Standards (2L Standards). The
groundwater sample collected from the Triangle Well contained several compounds exceeding the
2L Standards and bis(2-ethylhexyl)phthalate was present above the Gross Contamination Levels
(GCLs). Concentrations were also compared to the North Carolina 15A NCAC 02B Water
Quality Standards for Surface Waters (2B) or, if no 2B Standard is established, the EPA National
Site Check Report March 3, 2020
Piedmont Property (Incident #10433) ATC Project No. SLP1043302

Recommended Water Quality Criteria (NRWQC) for Aquatic Life & Human Health (ALHH).
Compounds exceeding the 2B or EPA NRWQC ALHH Standards included benzene,
ethylbenzene, bis(2-ethylhexyl)phthalate, and lead.

Based on the results of the soil and groundwater sampling event and the lack of definitive locations
of the former UST components, ATC recommends the following:

 Performing passive soil gas sampling across the source property to determine potential
areas of petroleum impact in an effort to locate the source of groundwater impacts; and
 Obtaining consent to connect water supply well WSW-5 (potable well located 650 feet
south of the site) to municipal water.

3.0 SITE DESCRIPTION

3.1 Site Characterization

The Piedmont Property site is located on the southeast corner of the intersection of Outer Loop
Road and US Highway 15 on the north side of Oxford, Granville County, North Carolina. The site
is currently within the NCDOT right-of-way. The site is bound to the north by Outer Loop Road
(US Highway 158), to the south and east by the Rose Mart gas station (which has no reported
release), and to the west by US Highway 15. Based on information obtained from the NCDEQ,
there were three USTs of unknown sizes and contents removed from the site in 1987. Based on
information included in the Site Receptor Report dated October 11, 2019, prepared by ATC,
municipal water is available to properties in the area; however there are four water supply wells
located within 1,500 feet of the site. One active potable water supply well is located between 500 to
1,000 feet, and three water supply wells of unknown usage are located between 1,000 and 1,500
feet. A site topographic map is included as Figure 1 and a site map depicting pertinent site features
is included as Figure 2. As shown on Figure 1, a surface water body, Jordan Creek, is located
approximately 200 feet south of the former UST basin.

3.2 Site Background

The parcel on which the former gas station was located (Piedmont Property) was acquired by the
NCDOT in 1987 as part of the right-of-way for the intersection of US Highway 15 and US
Highway 158. The NCDOT purchased the property from Ms. Julia A. Poteat. At the time of
acquisition, the property was operating as a service station with gasoline sales. The property
Site Check Report March 3, 2020
Piedmont Property (Incident #10433) ATC Project No. SLP1043302

included three USTs of unspecified sizes and contents, a water supply well, and several
structures. The USTs were pumped out by Ms. Poteat prior to NCDOT acquisition. In
November of 1987, the NCDOT removed the USTs, abandoned the water supply well, and
demolished all of the structures on the parcel.

In February of 1993, the owners of the adjacent property to the southeast (National Bank of
Oxford) claimed that contamination had leaked from the NCDOT right-of-way onto their
property as determined by a limited site assessment that included soil and groundwater sampling
on the edge of the bank property closest to the NCDOT right-of-way. The laboratory analytical
results for the monitoring well installed by Triangle Environmental indicated benzene above the
2L Standard at 545 micrograms per liter (g/L). Other petroleum hydrocarbons were detected,
but below the 2L Standard. Rose Oil Company, the prospective buyer for the southeast-adjacent
parcel, submitted the results of the limited site assessment to the NCDEQ. In response, the
NCDEQ issued a letter requesting the NCDOT perform an assessment of the former UST basin.

On September 13, 1993, the NCDOT advanced four soil borings in the vicinity of the former
UST basin. Soil sample S-2 exhibited concentrations of Total Petroleum Hydrocarbons (TPH) –
Gasoline Range Organics (GRO) exceeding the NCDEQ Action Levels. None of the soil
samples contained concentrations exceeding the TPH – Diesel Range Organics (DRO) Action
Level. Soil sample location B4 was converted to a monitoring well (MW-1). This well is
located upgradient of the monitoring well installed during the limited site assessment performed
for Rose Oil Company. Monitoring well MW-1 exhibited concentrations of benzene exceeding
the GCL and toluene, ethylbenzene, total xylenes, and methyl tert-butyl ether (MTBE) exceeding
the 2L Standards.

In November 2006, Groundwater Management Associates, Inc. (GMA) performed a site
reconnaissance/sensitive receptor survey for the site. In GMA’s report, they indicate that a
Pollution Incident Reporting Form assigned the site a priority ranking of 70E and that no water
supply wells were identified within 1,500 feet of the site. Jordan Creek was identified 200 feet
south of the site. The Piedmont Property was referred to the State Lead Program because the
UST owner is deceased. The site was accepted into the State Lead Program on February 15,
1994. GMA identified two potable water supply wells and one well of unknown status within
1,000 feet of the site. Additionally, two non-potable water supply wells were identified between
1,000 and 1,500 feet of the site.

A Site Receptor Report prepared by ATC was submitted on October 11, 2019. Municipal water
is available to the site and site vicinity. Based on ATC’s findings, there are four water supply wells
located within 1,500 feet of the site. One active potable water supply well is located between 500 to
1,000 feet, and three water supply wells of unknown usage (properties have active municipal water
accounts) are located between 1,000 and 1,500 feet. A Potential Receptor Map is included as
Figure 3. Information regarding these water supply wells is included in Table 1. Historical water
supply well samples are included in Table 2. Jordan Creek was identified approximately 200 feet
south of the site and is shown on Figure 3. Jordan Creek is classified as a Class C (Aquatic Life,
Secondary Recreation, Fresh Water), Nutrient Sensitive Water (NSW) water body.

4.0 SOIL SAMPLING

As authorized in Task Authorization TA-02, ATC supervised the advancement of one soil boring
and subsequent installation of one temporary monitoring well TW-1 in the former UST basin.
Regional Probing Services advanced the soil boring to approximately 8.5 feet below ground
surface (bgs). Soil samples were collected in five foot intervals. During the soil sampling
activities, soils were screened using a photoionization detector (PID). Groundwater was
encountered in the boring at approximately 6.70 feet bgs and the sample interval from 0 to 5 feet
bgs was collected for laboratory analysis. The soil sample was analyzed for Environmental
Protection Agency (EPA) Method 8260, EPA Method 8270, Massachusetts Department of
Environmental Protection (MADEP) Extractable Petroleum Hydrocarbons (EPH), and MADEP
Volatile Petroleum Hydrocarbons (VPH). Based on the analytical results, the soil sample
exhibited a concentration of acetone above the laboratory detection limit, but below the Soil-to-
Groundwater MSCC. No other compounds were detected. A table summarizing the soil
analytical results is included in Table 3. Approximate locations of the soil samples collected to
date are included on Figure 4. It should be noted that correlations between maps in historical
reports, field observations, historical aerial photographs, and topographic maps could not
definitively be made. Copies of these resources are included in Appendix A. Field notes for the
January 14, 2020 sampling event are included in Appendix B. A soil boring log is included in
Appendix C. The lithology encountered in the soil boring predominantly consisted of clayey to
silty sand. The laboratory analytical report and chain-of-custody forms are included in Appendix
D.

As part of ATC’s quality assurance and quality control (QA and QC) measures, a data review of
the laboratory report was conducted. During the review, it was concluded that samples were
Site Check Report March 3, 2020
Piedmont Property (Incident #10433) ATC Project No. SLP1043302

received by the laboratory in acceptable condition. The samples were analyzed within the
correct holding times, and the chain of custody was properly completed by all parties. The
laboratory QC report shows an internal blank was analyzed for each method that was used for the
original samples. The laboratory fortified blank (LFB) and laboratory control sample (LCS) data
results were also provided for each analytical method. Refer to the laboratory report in
Appendix D for details regarding QA results for the laboratory samples and any noted
exceptions. Overall, ATC concludes that the laboratory results are usable and any exceptions do
not significantly impact the conclusions presented in this report.

5.0 TEMPORARY WELL INSTALLATION

ATC supervised the installation of one temporary monitoring well, Temp Well-1, in the former
UST basin within the NCDOT right-of-way. Regional Probing Services installed the temporary
well to a depth of approximately 8.5 feet using direct push technology. The temporary well was
screened from approximately 3.5 feet to 8.5 feet bgs. Groundwater was encountered at
approximately 6.70 feet bgs. The boring log with monitoring well construction information is
included in Appendix C.

6.0 GROUNDWATER CHARACTERIZATION

6.1 Groundwater Levels

On January 14, 2020, ATC gauged permanent monitoring well Triangle Well and temporary
monitoring well Temp Well-1 using an oil/water interface probe. Light non-aqueous phase liquid
was not detected. Depth to groundwater was measured at 7.31 feet bgs in Triangle Well and 6.70
feet bgs in Temp Well-1. Field notes from the sampling event are included in Appendix B.

6.2 Groundwater Sampling

On January 14, 2020, groundwater samples were collected from permanent monitoring well
Triangle Well and temporary well Temp Well-1. The samples was collected in laboratory
approved containers, packed in ice and delivered under chain-of-custody protocol to SGS for
analyses. The groundwater samples collected were analyzed for volatile organic compounds
(VOCs) by EPA Method 6200B. Additionally, the sample collected from Triangle Well was
further analyzed for 1,2-dibromoethane by EPA Method 504.1, semi-VOCs by EPA 625, and
lead and chromium by EPA Method 6020.

6.3 Groundwater Analytical Results

The laboratory analytical results for Triangle Well indicated bis(2-ethylhexyl)phthalate present
above GCL at a concentration of 964 g/L. Benzene, ethylbenzene, naphthalene, n-
butylbenzene, isopropylbenzene, n-propylbenzene, 1-methylnaphthalene, 2-methylnaphthalene,
and lead were present above the 2L Standards in Triangle Well, but below the GCLs.
Concentrations were also compared to the 2B Standards or, if no 2B Standard is established, the
EPA NRWQC for ALHH. Compounds exceeding the 2B or EPA NRWQC ALHH Standards
included benzene, ethylbenzene, bis(2-ethylhexyl)phthalate, and lead. The laboratory analytical
results for Temp Well-1 indicated the presence of benzene above the 2L and 2B Standards.
Groundwater analytical data are summarized in Table 4. The laboratory analytical report and
chain-of-custody forms are included in Appendix D. QA/QC measures are discussed in Section
4.0.

7.0 CONCLUSIONS

On behalf of the Trust Fund Branch of the UST Section, ATC has completed a Site Check
Report for the Piedmont Property site located at the southeast corner of the intersection of Outer
Loop Road and US Highway 15 in Oxford, Granville County, North Carolina. This report
documents the advancement of one soil boring, subsequent installation of temporary monitoring
well Temp Well-1, and sampling of one off-site permanent monitoring well. The laboratory
results indicated that the soils in the former UST basin are not impacted above the Soil-to-
Groundwater MSCCs. The groundwater samples collected from the temporary well and off-site
permanent well indicated impacts above the 2L Standards and bis(2-ethylhexyl)phthalate
exceeding the GCLs. One active potable water supply well is located between 500 to 1,000 feet, and
three water supply wells of unknown usage (properties have active municipal water accounts) are
located between 1,000 and 1,500 feet. Jordan Creek, a surface water body, is located
approximately 200 feet south of the site. Impacts were present above the 2B (or EPA NRWQC
for ALHH) in both Triangle Well and Temp Well-1.

Based on the results of the soil and groundwater sampling event and the lack of definitive locations
of the former UST components, ATC recommends the following:

 Performing passive soil gas sampling across the source property to determine potential
areas of petroleum impact in an effort to locate the source of groundwater impacts; and

Dear Ms.Allyn,
The final report for SGS Job LA60927 has been amended from the original. This report replaces in its entirety any previously submitted copy.
The Volatile Organics Compounds (VOCs) by Standard Methods 6200B results for the sample Temp Well-1 were omitted from the original laboratory report due to a laboratory error. The VOCs for Temp Well-1 are included in this laboratory report. The sample was analyzed at 10x dilution so reporting limits are slightly elevated. I apologize for the error and the inconvenience. Sincerely,
Amy Jackson Environment, Health and Safety Project Manager SGS-Scott
