EXECUTIVE SUMMARY

The former Phelps Amoco site is located along US Highway 64 West, west of the Town of Creswell,
Washington County, North Carolina. The adjoining properties are agricultural and residential. Municipal
water is available to the surrounding properties. The risk classification is currently ranked as intermediate
due to the historical presence of free product and ground water contamination exceeding the gross
contamination level (GCL) for benzene.

On November 11, 2015, twelve Type II monitoring wells were gauged, purged and/or sampled.
Concentrations of requested method constituents that exceeded the Maximum Allowable Concentrations
were reported in the ground water samples collected from MW-14 and MW-21. The concentration of
benzene reported in the ground water sample collected from MW-21 exceeded the GCL. Absorbent
booms were replaced in MW-14 and MW-21 upon the completion of the November 2015 sampling event.

GRI recommends that Additional Aggressive Fluid Vapor Recovery (AFVR) events should be conducted
in order to reduce contamination levels in MW-21. The AFVR event(s) could be enhanced with the
installation of a recovery well between MW-14 and MW-21. Absorbent boom maintenance for MW-14
and MW-21 should continue until the next sampling event. Semi-annual ground water monitoring should
continue at the site. The next ground water monitoring event is tentatively scheduled for May 2016.

1.0 SITE HISTORY AND CHARACTERIZATION
The site is a former convenience store and petroleum retail facility. Soil and ground water assessment
activities commenced at the site in response to a release reported in May 1994 during the closure of three
4,000-gallon gasoline and one 1,000-gallon diesel USTs. A new UST system consisting of one 6,000-
gallon gasoline, two 4,000-gallon gasoline, one 1,000-gallon diesel and one 1,000-gallon kerosene USTs
was installed in the former UST basin in July 1994. A Corrective Action Plan (CAP) for the site
developed by TRC Triangle (TRC) proposed remediation using soil excavation followed by natural
attenuation and water supply well abandonment. The proposed remediation method was designed to
accommodate the North Carolina Department of Transportation (NCDOT) plans to raze the facility and
construct a new US Highway 64 over the site. As part of the Corrective Action Plan, the UST system
installed in July 1994, associated pumps and product piping, as well as 3,909.89 tons of contaminated soil
were removed from the site in March and April 2002 by Coastal Environmental Services, Inc. (CES).

Eleven Type II monitoring wells (MW-1 through MW-3 and MW-5 through MW-8 and MW-10 through
MW-13) and two Type III monitoring wells (MWD-4 and MWD-9) were installed at the site during
previous ground water assessment activities. Prior to excavation activities, CES abandoned monitoring
wells MW-1 through MW-5, MW-7, MW-8, MW-9, MW-12 and water supply well DW-1. Monitoring
wells MW-10 and MW-11 and water supply wells DW-2 and DW-3 were reportedly destroyed by the
NCDOT and therefore were not properly abandoned. Nine additional Type II monitoring wells (MW-14
through MW-22) were installed by Geological Resources, Inc. (GRI) to replace monitoring wells
abandoned and/or destroyed during CAP implementation activities and NCDOT construction in 2002.

Assessment activities conducted prior to the July 2008 updated receptor survey 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.

2.0 CURRENT SITE ACTIVITIES
The purpose of this report is to present the results of the ground water assessment activities conducted on
November 11 2015, at the former Phelps Amoco site located along US Highway 64 West, west of the
Town of Creswell, Washington County, North Carolina (Figure 1). The activities were conducted in
accordance with GRI proposal number 15-376 which was submitted to NCDEQ on November 17, 2014
and approved as Task Authorization No. 12613-25 on June 25, 2015. The purpose of the activities was to
obtain current ground water quality data for the site.

3.0 GROUND WATER QUALITY
Twelve Type II monitoring wells (MW-6 and MW-14 through MW-24) were gauged, purged and
sampled on November 11, 2015. No free product was observed during the November 2015 sampling
event. The depths to ground water in the Type II monitoring wells during the November 2015 sampling
event ranged from 0.86 to 8.50 feet below the tops of well casings. Ground water elevations in the Type
II monitoring wells relative to a temporary benchmark assumed by the previous consultant ranged from
97.25 to 98.41 feet. Based on this information, ground water flow direction is generally convergent in the
vicinity of the former UST system with an average horizontal hydraulic gradient of less than 0.01 feet per
foot. A Water Table Surface Map for the November 2015 sampling event has been included as Figure 3.
A summary of well construction information including ground water elevation data is presented in Table
1.

Seven Type II monitoring wells (MW-6, MW-14, MW-15 and MW-21 through MW-24) were purged and
sampled on November 11, 2015. Laboratory analyses were performed on the ground water samples
collected from the monitoring wells during the November 2015 sampling event for volatile organic
compounds (VOCs) using EPA Method 6200B.

Concentrations of one or more BTEX constituents, MTBE, naphthalene, 1,2-dichloroethane, n-
propylbenzene, 1,2,4-trimethylbenzene and/or 1,3,5-trimethylbenzene that exceeded the Maximum
Allowable Concentrations (MACs) specified in T15A NCAC 2L.0202 were reported in the ground water
samples collected from MW-14 and MW-21. The concentration of benzene reported in the ground water
sample collected from MW-21 exceeded the Gross Contamination Level (GCL). A Ground Water
Quality Map based on data from the November 11, 2015 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. Upon completion of the November 2015 sampling event,
absorbent booms were replaced in MW-14 and MW-21.

4.0 CONCLUSIONS AND RECOMMENDATIONS
 The average depth to water during the November 2015 sampling event was 6.56 feet. Ground
water flow in the vicinity of the former UST system was generally convergent at the site with an
average horizontal hydraulic gradient of less than 0.01 feet per foot.
 Concentrations of one or more BTEX constituents, MTBE, naphthalene, 1,2-dichloroethane, n-
propylbenzene, 1,2,4-trimethylbenzene and/or 1,3,5-trimethylbenzene that exceeded the MACs

3
were reported in the ground water samples collected from MW-14 and MW-21. The
concentration of benzene reported in the ground water sample collected from MW-21 exceeded
the GCL.
 Absorbent booms were re-installed in MW-14 and MW-21 following the completion of the
November 2015 sampling event.
 GRI recommends that Additional Aggressive Fluid Vapor Recovery (AFVR) events should be
conducted in order to reduce contamination levels in MW-21. The AFVR event(s) could be
enhanced with the installation of a recovery well between MW-14 and MW-21. Absorbent boom
maintenance for MW-14 and MW-21 should continue until the next sampling event. Semi-annual
ground water monitoring should continue at the site. The next ground water monitoring event is
tentatively scheduled for May 2016.
