EXECUTIVE SUMMARY
Tripp’s Service Station is located at 6682 US Hwy 258 North in Farmville, Greene County, North Carolina.
The site is currently owned by William Everette Murphrey and is vacant. The adjoining properties are a
mixture of single family residential and agricultural properties. According to the information determined
during receptor survey activities, four water supply wells were identified within 1,500 feet of the site. One
inactive water supply well is within 200 feet of the site. Public water is available to the site and
surrounding properties within a 1,500-foot radius of the site.

A release was discovered in December of 1990 during construction activities on service station canopy.

A CAP was submitted by UTTS Environmental in February 1992; a pump and treat system was proposed
and installed at the site. This system was composed of four recovery wells that operated intermittently
from 1991 to 2001.

On July 22, 2013, one 6,000-gallon and one 4,000-gallon gasoline USTs were removed from the site.

On July 8, 2019, six monitoring wells were gauged, purged and/or sampled. The maximum allowable
concentrations (MACs) were below the concentrations of MTBE and/or naphthalene reported in the
ground water samples collected from MW-3 and MW-11R. Gross contamination levels (GCLs) were above
all of the reported contaminant concentrations.

Since July 2015 the contaminant mass has decreased by 89% through natural attenuation.

Based on this information, the contaminate plume is decreasing. A plume stability analyses should be
conducted. If favorable results are achieved, the site should be closed with a notice of residual petroleum
(NRP) for soil and groundwater.

1.0 SITE HISTORY AND CHARACTERIZATION
Geological Resources, Inc. (GRI) presents the results of the July 2019 receptor survey and the ground water
sampling event at the Tripp’s Service Station site; located at 6682 US Hwy 258 North in Farmville, Greene
County, North Carolina (Figure 1). These activities were conducted in accordance with GRI Proposal No.
19-114, which was submitted to the North Carolina Department of Environmental Quality (NCDEQ) on
February 13, 2019, and was approved as Task Authorization No. 6433-30 on February 22, 2019. State
correspondence has been included as Appendix A.

The site is currently owned by William Murphrey and is currently vacant. A release was discovered in
December of 1990 during construction activities. Reportedly, one 2,000-gallon gasoline UST was closed-
in-place in 2003. On July 22, 2013, one 6,000-gallon and one 4,000-gallon gasoline USTs were removed
from the site. A pump and treat remediation system was installed at the site in 1991 and operated
intermittently from 1991 to 2001; the remediation system was decommissioned in July-August 2013
during soil excavation activities. The site is currently ranked as high risk due to one inactive water supply
well located within 200 feet of 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:

The site and surrounding area is a mixture of single family residential and agricultural properties. The site
contains one buildings (former store) and is primarily capped with gravel. The overall topography at the
site is relatively flat. No surface water bodies were identified within a 500-foot radius of the site. Eleven
Type II monitoring wells (MW-1 through MW-11) , one Type III telescoping well DW-1 and four recovery
wells (RW-A, RW-B, RW-1 and RW-2) were installed at the site during previous ground water assessment
activities. Wells MW-10, MW-11, RW-A, RW-B, RW-2, MW-4, and DW-1 have been abandoned or
destroyed. Monitor well MW-11R was installed to replace MW-11 in 2015. A Site Map showing the
locations of the monitoring wells and the structures on-site has been included as Figure 2.

A Corrective Action Plan (CAP) was submitted by UTTS Environmental in February 1992, that proposed to
remove free product and reduce contaminant concentrations to at or below gross contamination levels

(GCLs) from the site utilizing a pump and treat system. This system was composed of four recovery wells
that operated intermittently from 1991 to 2001.

On July 22, 2013, one 6,000-gallon and one 4,000-gallon gasoline USTs were removed from the site.

In June 2015, additional soil excavation activities were initiated in the immediate vicinity of MW-11 to
reduce the ground contaminant levels.

On July 8, 2019, GRI personnel conducted an updated receptor survey at the site. Four water supply wells
were identified within a 1,500-foot radius of the site. One inactive water supply well was found within
200 feet of the site. Well owners were contacted to determine if they were willing to abandon their
respective wells. No responses have been received at the submittal of this report. County water is
available to the site and surrounding properties. Water Supply Well information is include in Table 3 and
adjacent property owner information is presented in Table 4. A Site Vicinity Map showing the adjacent
properties has been included as Figure 3.
2.0 PRESENTATION OF CURRENT SITE ASSESSMENT INFORMATION/ COMPARISON TO HISTORICAL
ASSESSMENT INFORMATION
On July 8, 2019, six Type II monitoring wells (MW-2, MW-3, MW-5, MW-7, MW-11R and MW-12) and one
recovery well (RW-1) were gauged, purged and/or sampled. MW-3 could not be effectively purged due
to an obstruction in well. Depths to ground water in the Type II monitoring wells ranged from 4.38 feet
to 7.23 feet. Ground water elevations in the Type II monitoring wells ranged from 93.95 feet to 95.53
feet. Ground water flow was generally to the southeast with a horizontal gradient of approximately 0.01
feet per foot. Well construction and gauging information is presented in Table 4. 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 is shown below:

Ground water samples collected from the monitoring wells were submitted for laboratory analyses using
EPA Method 6200B. The maximum allowable concentrations (MACs) as specified in T15A NCAC 2L.0202
were below the concentrations of MTBE and/or naphthalene reported in the ground water samples
collected from MW-3 and MW-11R. GCLs were above all of the reported contaminant concentrations. A
summary of the analytical results for ground water samples collected on July 8, 2019 is presented in Table

The baseline contaminant mass at the site was determined based on the total BTEX, MTBE and
naphthalene concentrations from the July 2015 ground water sampling event as well as the maximum
historical water column height observed. The July 2015 sampling event was the 1st ground water sampling
event post soil excavation. Based on these data, the contaminant mass has been reduced by 89%.
Contaminant mass reduction calculations have been included as Appendix C. A map of the contaminant
mass area has been included as Figure 6. A chart depicting the overall declining trend in contaminant
mass is shown below:

The site is located in the Coastal Plain Physiographic Province of North Carolina. The site overlays the
Black Creek aquifer. The water table has a seasonal high depth to water of approximately two to eight
feet below ground surface.

3.0 FREE PRODUCT REMOVAL
Free product has historically been present in site recovery wells; however, free product has not been
observed since September 1991. Recovery wells RW-A and RW-B were removed during the July-August
2013 soil excavation activates.
4.0 NATURAL ATTENUATION / NATURAL SOURCE ZONE DEPLETION STATUS
No natural attenuation monitoring plan is currently in place at the site; however, natural attenuation is
currently effectively reducing contaminate mass.
5.0 CONCLUSIONS
 On July 8, 2019, an updated receptor survey was completed. Four water supply wells were
identified within 1,500 feet of the site. One Water supply well was found within 200 feet of the
site.
 On July 8, 2019, six Type II monitoring wells and one recovery well were gauged, purged and/or
sampled. Ground water flow was generally to the southeast with a horizontal gradient of
approximately 0.01 feet per foot.
 The MACs were below the concentrations of MTBE and/or naphthalene reported in the ground
water samples collected from MW-3 and MW-11R. GCLs were above all of the reported
contaminant concentrations.
 Contaminant mass has decreased by 89% from 2015 to present through natural attenuation.
 Based on this information, the contaminant plume is decreasing. A plume stability analyses
should be conducted. If favorable results are achieved, the site should be closed with a NRP for
soil and groundwater.
6.0 LIMITATIONS
