EXECUTIVE SUMMARY

The former Noah Roberson Store is located at 8941 NC Highway 171, in Williamston, Martin County,
North Carolina. According to available information, one 1,000-gallon gasoline and two 550-gallon
gasoline underground storage tanks, associated pumps and product piping were removed from the site in
December 1993. The site risk classification is currently High due to the presence of one water supply
well within a 250-foot radius of the site and two potable water supply wells within a 1,000-foot radius of
the site.

On January 8, 2019, four monitoring wells and one water supply well were gauged, purged and/or
sampled. Concentrations of requested method constituents that exceeded the Maximum Allowable
Concentrations specified in T15A NCAC 2L.0202 were reported in the ground water samples collected
from MW-1, MW-5, MW-12 and MW-13. None of the reported contaminant concentrations exceeded
the Gross Contamination Levels. No concentrations of requested method constituents were reported in
the water sample collected from WSW-1.

Universal Remediation BioSocks were installed in MW-1, MW-5, MW-12 and MW-13 upon completion
of the January 2019 sampling event.

Based on this information, contaminant concentrations appear to be decreasing. A plume stability
analysis should be conducted. Additional attempts to abandon WSW-1 should be pursued. Semi-annual
ground water monitoring should continue at the site until the risk classification can be lowered. The next
monitoring event is tentatively scheduled for July 2019.

1.0 SITE HISTORY AND CHARACTERIZATION
The former Noah Roberson Store site is located at 8941 NC Highway 171 in Williamston, Martin County,
North Carolina (Figure 1). According to available information, one 1,000-gallon gasoline and two 550-
gallon gasoline underground storage tanks (USTs), associated pumps and product piping were removed
from the site in December 1993 by Coastal Environmental Services, Inc. (Coastal). Sixteen Type II
monitoring wells (MW-1, MW-2, MW-3 and MW-5 through MW-17) and one Type III monitoring well
(MWD-4) were installed at the site during previous ground water assessment activities conducted by
Coastal. Two recovery wells (RW-1 and RW-2) were also installed during corrective action
implementation activities. Seven additional Type II monitoring wells (MW-8R, MW-16R and MW-18
through MW-22) were installed on July 8-9, 2009 to delineate the horizontal extent of the hydrocarbon
plume. Of these new wells, MW-8R, MW-19 and MW-20 were destroyed by vandals between July and
August 13, 2009. Monitoring well MW-8R was subsequently repaired. Monitoring well MW-15 was
destroyed by farm equipment during past site activities. One Type II monitoring well (MW-23) was
installed on September 28, 2011.

A Corrective Action Plan was developed for the site by Triangle Environmental, Inc. and proposed
remediation using a ground water pump and treat system. This system was installed by CES Engineering,
PC (CES) and activated in March 1999. The remediation system was shut down between January and
September 2005 due to lack of funding from the NCDENR UST Trust Fund. The remediation system
was restarted and operated at the site between July 2009 and January 2012.

Please note that certain information contained in this report was obtained under the supervision of
previous consultants. Although Geological Resources, Inc. (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 previous submittals for further historical information regarding the site.

2.0 CURRENT SITE ASSESSMENT
The purpose of this report is to present the results of the ground water sampling event conducted on
January 8, 2019. The activities were conducted in accordance with GRI proposal number 18-658 which
was submitted to NCDEQ on November 27, 2018, and approved as Task Authorization Number 11759-
053 on November 28, 2018. The purpose of the activities was to obtain current ground water quality data
for the site.

3.0 GROUND WATER QUALITY
On January 8, 2019, four Type II monitoring wells (MW-1, MW-5, MW-12 and MW-13) and one water
supply well (WSW-1) were gauged, purged and/or sampled. The depths to ground water in the Type II
monitoring wells during the January 2019 sampling event ranged from 1.60 to 2.40 feet below the tops of
well casings. Ground water elevations in the Type II monitoring wells relative to a temporary benchmark
with an assumed datum of 100.00 feet ranged from 96.44 to 98.08 feet. Based on this information,
ground water flow across the site was generally toward the northeast. The average horizontal hydraulic
gradient at the site during the January 2019 sampling event was approximately 0.02 feet per foot. A Site
Map showing the locations of monitoring wells and structures on-site is included as Figure 2. A Water
Table Surface Map based on data obtained from the Type II wells in January 2019 is included as Figure
3. A summary of well construction and gauging information is presented in Table 1.

Laboratory analyses were performed on the ground water samples collected from the monitoring wells for
volatile organic compounds using EPA Method 6200B. Concentrations of benzene, naphthalene, 1,2-
dichloroethane, n-propylbenzene and/or 1,2,4-trimethylbenzene that exceeded the Maximum Allowable
Concentrations (MACs) specified in T15A NCAC 2L.0202 were reported in the ground water samples
collected from MW-1, MW-5, MW-12 and MW-13. No constituents exceeded the Gross Contamination
Levels (GCLs), reported was an estimated value. No detectable concentrations of requested method
constituents were reported in the water sample collected from WSW-1. Ground Water Quality Map based
on data from the January 2019 sampling event has been included as Figure 4. A summary of ground
water sample analytical results is presented in Table 2. A complete laboratory report has been included
as Appendix A.

Universal Remediation BioSocks were installed in MW-1, MW-5, MW-12 and MW-13 upon completion
of the January 2019 sampling event.

4.0 CONCLUSIONS AND RECOMMENDATIONS
 The average depth to ground water in the Type II monitoring wells in January 2019 was 2.08 feet
below the tops of well casings. Ground water flow across the site was generally toward the
northeast with an average horizontal hydraulic gradient of approximately 0.02 feet per foot.
 Concentrations of benzene, naphthalene, 1,2-dichloroethane, n-propylbenzene and/or 1,2,4-
trimethylbenzene that exceeded the MACs were reported in the ground water samples collected
from MW-1, MW-5, MW-12 and MW-13. None of the reported contaminant concentrations

exceeded the GCLs.
 No detectable concentrations of requested method constituents were reported in the water sample
collected from WSW-1.
 Universal Remediation BioSocks were installed in MW-1, MW-5, MW-12 and MW-13 upon
completion of the January 2019 sampling event.
 Based on this information, contaminant concentrations appear to be decreasing. A plume stability
analysis should be conducted. Additional attempts to abandon WSW-1 should be pursued. Semi-
annual ground water monitoring should continue at the site until the risk classification can be
lowered. The next monitoring event is tentatively scheduled for July 2019.

Notes:
• **: If free product is present in a well, ground water elevation should be calculated by: (Top of Casing Elevation - Depth to Water) +
(Free Product thickness x 0.8581)
• Monitoring wells MW-8R, MW-18, MW-19 and MW-20 were each installed with 4-feet of stand up casing.
• Top-of-casing elevations for monitoring wells MW-16R, MW-18, MW-21 and MW-22 were surveyed by GRI personnel on 9/29/09.
• Monitoring well MW-8R was repaired during the December 2009 event. Top-of-casing elevation for MW-8R was subsequently resurveyed by GRI personnel.
