EXECUTIVE SUMMARY
Perrytown Service Center is located at 526 Sand Hill Road in Colerain, Bertie County, North Carolina. The
site is currently owned by Stewart J. and William S. White and operated as a petroleum retail facility.
Unknown quantities of petroleum products were released to the subsurface. According to available
information, two 1,000-gallon gasoline and one 550-gallon gasoline underground storage tanks were
removed from the site in February 1993. One 2,000-gallon gasoline, one 3,000-gasoline and one 2,000-
gallon diesel USTs remain in use at the site. The adjoining properties are a mixture of residential and
commercial properties. One inactive water supply well (WSW-1) was identified within a 250-foot radius
of the site. Two potable water supply wells (WSW-3 and WSW-8) were identified within a 1,000-foot
radius of the site. Please note, WSW-1 was abandoned in January 2018. The site is currently ranked as
high risk due to its proximity to potable water supply wells. Public water is available to the site and
surrounding properties within a 1,500-foot radius of the site.

On September 13, 2021, eleven monitoring wells and one recovery well were gauged, purged and
sampled. Free product was not observed during the September 2021 sampling event. Water supply well
WSW-2 was inaccessible and unable to be sampled in September 2021. Ground water samples collected
from the monitoring wells were submitted for laboratory analyses using EPA Method 6200B.
Concentrations of individual BTEX constituents, naphthalene, n-propylbenzene, methyl chloride, 1,2-DCA,
p-isopropyltoluene, 1,2,4-trimethylbenzene and/or 1,3,5-trimethylbenzene that exceeded the MACs
were reported in the ground water samples collected from MW-2, MW-9, MW-10, MW-12, MW-23
through MW-27, MW-29, and RW-1. All of the reported contaminant concentrations were less than the
GCLs.

Contaminant mass at the site has decreased by 64.2% since June 2020.

Based on this information, WSW-3 appears to be up-gradient to the release and is no longer in use. The
property where WSW-3 is located appears to be vacant and/or abandoned. An additional ground water
sampling event including MW-16, MW-17 and MW-19 should be conducted in April 2022 in order to assess
the risk to WSW-3. The stability of the contaminant plume should be evaluated. Following the next
sampling event, if WSW-3 does not appear to be at risk and the plume is stable and/or decreasing, then
the risk classification for the site should be reevaluated.

1.0 SITE HISTORY AND CHARACTERIZATION
GRI presents the results of the September 2021 ground water sampling event at the Perrytown Service
Center site located at 526 Sand Hill Road in Colerain, Bertie County, North Carolina (Figure 1). These
activities were conducted in accordance with GRI Proposal No. 21-568, which was submitted to NCDEQ
on September 1, 2021, and was approved as Task Authorization No. 13261-50 on September 3, 2021.
State correspondence has been included as Appendix A.

The site is currently owned by Stewart J. and William S. White and operated as a petroleum retail facility.
Unknown quantities of petroleum products were released to the subsurface. According to available
information, two 1,000-gallon gasoline and one 550-gallon gasoline underground storage tanks were
removed from the site in February 1993. One 2,000-gallon gasoline, one 3,000-gasoline and one 2,000-
gallon diesel USTs remain in use at the site. UST owner/operator information and UST system information
are included as Tables 1 and 2, respectively. The Registered Tank Report is shown below:

On November 28, 2016, an update to the receptor survey was completed. The adjoining properties are a
mixture of residential and commercial properties. One inactive water supply well (WSW-1) was identified
within a 250-foot radius of the site. Two potable water supply wells (WSW-3 and WSW-8) were identified
within a 1,000-foot radius of the site. Please note, WSW-1 was abandoned in January 2018. The property
where WSW-3 is located is now vacant and/or abandoned, and the well is no longer in use. The site is
currently ranked as high risk due to its proximity to potable water supply wells. Public water is available
to the site and surrounding properties within a 1,500-foot radius of the site. No surface water bodies
were identified within 500 feet of the site. A Site Vicinity Map showing the adjacent properties has been
included as Figure 2. A Site Map showing the locations of the monitoring wells and the structures on-site

has been included as Figure 3. Water supply well information is presented in Table 3. Adjacent property
owner information is presented in Table 4.
Please note that site activities conducted prior to the July 2009 updated receptor survey and ground water
sampling event were conducted by past consultants. Although GRI cannot verify the accuracy of
information obtained from previous reports, for the purposes of this report, it is assumed to be correct.
Please refer to past submittals for further historical information regarding the site.

A CAP proposing remediation of the site using a pump and treat system was completed in July 1998;
however, no projected milestones were established, and the CAP has never been fully implemented.
2.0 PRESENTATION OF CURRENT SITE ASSESSMENT INFORMATION/ COMPARISON TO HISTORICAL
ASSESSMENT INFORMATION
On September 13, 2021, eleven Type II monitoring wells (MW-2, MW-9, MW-10, MW-12, MW-23 through
MW- 27, MW-29 and MW-31) and one recovery well (RW-1) were gauged. Free product was not observed
during the September 2021 gauging event. Please note, WSW-2 was inaccessible and could not be
sampled. Depths to ground water in the Type II monitoring wells ranged from 5.90 feet to 6.75 feet below
the tops of well casings. Ground water elevations in the Type II monitoring wells ranged from 93.26 feet
to 93.94 feet. Ground water flow was generally toward the northwest with a horizontal gradient of less
than 0.01 feet per foot. No vertical gradient could be calculated since no telescoping well was gauged.
Well construction and gauging information is presented in Table 5. A Water Table Surface Map based on
the Type II monitoring wells is included as Figure 4. A summary of the current ground water gauging data

The baseline contaminant mass at the site was determined based on the total BTEX, MTBE and
naphthalene concentrations from the June 2020 ground water sampling event, as well as the maximum
historical water column height observed in the target area. The contaminant plume consists of one area
(Area 1) based on the benzene concentrations during the June 2020 ground water sampling event. The
contaminant mass has decreased by 64.2% in Area 1. Contaminant mass calculations have been included
as Appendix C. A map of the contaminant mass areas has been included as Figure 6. A chart depicting
the overall trend in contaminant mass is shown below:

The site is located in the Coastal Plain Physiographic Province of North Carolina. The water table has a
seasonal high depth to water of approximately 0.38 feet to 11.13 feet below ground surface (bgs).

Please note that while free product recovery events have continued, the full scope of the CAP has not
been implemented at the site. Please note that milestones were not established in the CAP.
3.0 FREE PRODUCT REMOVAL
Free product has historically been present in MW-10 and RW-1. No free product has been observed at
the site since March 2019. An absorbent boom was utilized in RW-1 between the March 2019 and June
2020 sampling events. Following the June 2020 sampling event, the absorbent boom was discarded.
4.0 NATURAL ATTENUATION / NATURAL SOURCE ZONE DEPLETION STATUS
MMPE events are being conducted at the site as the primary method of corrective action. Due to the site
being in the active remediation phase, no natural attenuation monitoring plan is currently in place at the
site. Contaminant reduction milestones were not proposed in the CAP.

5.0 CONCLUSIONS
 On September 13, 2021, eleven Type II monitoring wells and one recovery well were gauged,
purged and sampled. Please note, WSW-2 was inaccessible and could not be sampled. Free
product was not observed during the September 2021 sampling event. Ground water flow was
generally toward the northwest with a horizontal gradient of less than 0.01 feet per foot.
 Concentrations of individual BTEX constituents, naphthalene, n-propylbenzene, methyl chloride,
1,2-DCA, p-isopropyltoluene, 1,2,4-trimethylbenzene and/or 1,3,5-trimethylbenzene that
exceeded the MACs were reported in the ground water samples collected from MW-2, MW-9,
MW-10, MW-12, MW-23 through MW-27, MW-29 and RW-1. All of the reported contaminant
concentrations were less than the GCLs.
 Based on this information, WSW-3 appears to be up-gradient to the release and also is no longer
in use. An additional ground water sampling event including MW-16, MW-17 and MW-19 should
be conducted in April 2022 in order to assess the risk to WSW-3. The stability of the contaminant
plume should be evaluated. Following the next sampling event, if WSW-3 does not appear to be
at risk and the plume is stable and/or decreasing, then the risk classification for the site should be
reevaluated.

Notes:
• FP: Free Product
• Area of the contaminant plume is calculated from Figure 6
• Height of the water column is calculated by subtracting the average depth to water from the average well depth of the referenced monitoring wells
• Volume of the contaminant plume is calculated by multiplying the area of the plume by the average height of the water column during each sampling event
• Effective porosity is assumed based on the sub-surface soil profile obtained from well construction records and soil boring logs
• Total mass was calculated by multiplying the total contaminant concentrations for the sampling event with effective volume
• Contaminant mass cannot be calculated in wells containing FP; therefore, the total contaminant mass is based on the known concentrations in the area for each sampling event.
• When areas couldn’t be sampled, the last known concentrations were used in the calculations.
