EXECUTIVE SUMMARY
Trindale Mini Mart is located at 7619 NC Highway 62 in Trinity, Randolph County, North Carolina. The site
is currently owned by Joan Angel and is operated by Angel, LLC as a petroleum retail facility. Soil samples
collected during the initial abatement activities, during the removal of a 3,000-gallon kerosene UST in
August 2016, contained contaminant concentrations that exceeding the soil-to-water maximum
contaminant concentrations (MCCs). One 3,000-gallon kerosene, one 3,000-gallon gasoline, and one
4,000-gallon gasoline USTs were closed on April 27, 1990. One 7,000-gallon fuel oil UST was closed on
July 31, 1990. One 3,000-gallon kerosene UST was closed on August 1, 2016. Three 8,000-gallon gasoline
and associated pumps and product piping are active at the site. The adjoining properties are a mixture
residential and commercial properties. According to the information determined during receptor survey
activities, seven non-potable water supply wells were identified within 1,000 feet of the site. Public water
is available to the site and surrounding properties within a 1,500-foot radius of the site.

One Type II monitoring well (MW-1) was installed during the limited site assessment. A free product
thickness of 0.10 feet was measured in well MW-1 on April 16, 2017. Well MW-1 was again gauged on
September 5, 2020 and measured 5.91 feet of free product. Two 8-hour AFVR events have been
conducted on MW-1 to recover free product. On April 22, 2020, four additional Type II monitoring wells
(MW-2 through MW-5) were installed around the UST basin, to delineate free product. Wells MW-2
through MW-5 were installed to a total depth of 35 feet with a screened interval of 20 feet.

On April 22, 2020, five Type II monitoring wells (MW-1 through MW-5) were gauged, purged and/or
sampled. Free product was observed in monitoring well MW-1 and MW-3 with a free product thickness
of 0.64 feet and 0.03 feet, respectively; therefore, these wells were not sampled. Depths to ground water
in the Type II monitoring wells ranged from 22.04 feet to 23.99 feet relative to an arbitrary datum of 100
feet. Ground water elevations in the Type II monitoring wells ranged from 75.75 feet to 77.02 feet.
Ground water flow was generally to the northeast with a horizontal gradient of approximately 0.02 feet
per foot.

The MACs were below the concentrations of benzene, MTBE, TAA, p-isopropyltoluene, n-propylbenzene,
1,2,4-trimethylbenzene, methyl chloride, methylene chloride, 1,2-dichloroethane, 1-methylnaphthalene,
2-methylnaphthalene, C5-C8 aliphatics, C9-C22 aliphatics, C9-C10 aromatics, C9-C18 aliphatics, and/or
C11-C22 aromatics reported in the ground water samples collected from MW-2, MW-4 and MW-5. Free
product was found in MW-1 and MW-3. None of the contaminant concentrations were above the GCLs.

Based on this information, the risk classification for the site should remain intermediate risk. Past AFVR
events have been successful in reducing free product levels in MW-1; therefore, GRI recommends
continuing free product recovery using AFVR events. The ground water contaminant plume has not been
delineated at the site and GRI recommends installing additional monitoring wells to further delineate the
contaminant plume.

1.0 SITE HISTORY AND CHARACTERIZATION
Geological Resources, Inc. (GRI) presents the results of the April 2020 well installation activities and
ground water sampling event at the Trindale Mini Mart site; located at 7619 NC Highway 62 in Trinity,
Randolph County, North Carolina (Figure 1). These activities were conducted in accordance with GRI
Proposal No. 19-408, which was submitted to the North Carolina Department of Environmental Quality
(NCDEQ) on December 10, 2019 and was approved as Task Authorization No. 44719-7 on December 17,
2010. State correspondence has been included as Appendix A.

The site is currently owned by Joan S. Angel and is operated by Angels Inc. Trindale Mini Mart as a
petroleum retail facility. A release was discovered in August 2016 during the removal of a 3,000-gallon
kerosene UST at the site. One 3,000-gallon kerosene, one 3,000-gallon gasoline, and one 4,000-gallon
gasoline USTs were closed on April 27, 1990. One 7,000-gallon fuel oil UST was closed on July 31, 1990.
Three 8,000-gallon gasoline USTs and associated pumps and product piping are active 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:

The site and surrounding area is a mixture of multi-family residential, single family residential, and
commercial properties. The site contains a building and is primarily capped with concrete and asphalt.
The overall topography at the site is relatively flat. No surface water bodies were identified within a 500-
foot radius of the site. One Type II monitoring well (MW-1) was installed at the site during previous

ground water assessment activities. A Site Map showing the locations of the monitoring wells and the
structures on-site has been included as Figure 2.

On April 25, 2017, a receptor survey was conducted at the site. Seven non-potable water supply wells
were identified within a 1,000-foot radius of the site. Municipal water is available to the site and
surrounding properties. Adjacent property owner information is presented in Table 3. A Site Vicinity Map
showing the adjacent properties has been included as Figure 3.

Assessment activities are currently being conducted at the site. A Comprehensive Site Assessment (CSA)
nor a Corrective Action Plan (CAP) have been completed for the site. To date, two aggressive fluid/vapor
recovery (AFVR) events have been conducted at the site to recover free product.
2.0 MONITORING WELL INSTALLATION
On April 22, 2020, four additional Type II monitoring wells (MW-2 through MW-5) were installed around
the UST basin to delineate free product. Wells MW-2 through MW-5 were installed to total depths of 35
feet with screened intervals of 20 feet. Copies of the subsurface logs and well construction records have
been included in Appendix B. A photo of MW-2 through MW-5 are shown below:

3.0 PRESENTATION OF CURRENT SITE ASSESSMENT INFORMATION/ COMPARISON TO HISTORICAL
ASSESSMENT INFORMATION
On April 22, 2020, five Type II monitoring wells (MW-1 through MW-5) were gauged, purged and/or
sampled. Free product was observed in monitoring well MW-1 and MW-3 with a free product thickness
of 0.64 feet and 0.03 feet, respectively; therefore, these wells were not sampled. Depths to ground water
in the Type II monitoring wells ranged from 22.04 feet to 23.99 feet relative to an arbitrary datum of 100
feet. Ground water elevations in the Type II monitoring wells ranged from 75.75 feet to 77.02 feet.
Ground water flow was generally to the northeast with a horizontal gradient of approximately 0.02 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

MW-5 15 - 35 35 97.97 22.04 - 75.93

Ground water samples collected from the monitoring wells were submitted for laboratory analyses for
volatile organic compounds (VOCs) plus oxygenates using EPA Method 6200B, semi-VOCs (SVOCs) using
EPA Method 625.1, volatile and extractable petroleum hydrocarbons (VPH/EPH) using MADEP Methods.
The maximum allowable concentrations (MACs) as specified in T15A NCAC 2L.0202 were below the
concentrations of benzene, MTBE, TAA, p-isopropyltoluene, n-propylbenzene, 1,2,4-trimethylbenzene,
methyl chloride, methylene chloride, 1,2-dichloroethane, 1-methylnaphthalene, 2-methylnaphthalene,
C5-C8 aliphatics, C9-C22 aliphatics, C9-C10 aromatics, C9-C18 aliphatics, and/or C11-C22 aromatics
reported in the ground water samples collected from MW-2, MW-4 and MW-5. Free product was found
in MW-1 and MW-3. None of the reported contaminant concentrations found in MW-2, MW-4, and MW-
5 were above the gross contamination levels (GCLs). A summary of the analytical results for ground water
samples collected on April 22, 2020 is presented in Table 5. A Ground Water Quality Map based on the
April 2020 data is included as Figure 5. A complete report of laboratory analyses of the ground water
samples collected from the monitoring wells during the April 2020 sampling event has been included as
Appendix C. A summary of the current ground water analytical data is shown below:

The baseline contaminant mass at the site was determined based on the total BTEX, MTBE and
naphthalene concentrations from the April 2020 ground water sampling event as well as the maximum
historical water column height observed in each area. The contaminant plume was divided into two areas
(Areas 1 and 2) based on the extent of free product and benzene concentrations during the April 2020
ground water sampling event. Please note that the contaminant mass cannot be calculated in wells
containing free product. Once free product is removed from the site, changes in contaminant mass can
be calculated from future ground water sampling events. Contaminant mass calculations have been
included as Appendix D. A map of the contaminant mass areas has been included as Figure 6.

4.0 FREE PRODUCT REMOVAL
Free product has historically been present in monitoring well MW-1. An AFVR event was conducted on
November 22, 2017, and a subsequent AFVR event was again conducted in February 14, 2019 to recover
free product from MW-1. During the sampling event in April 2020, free product was found in MW-1 and
MW-3 at a thickness of 0.64 and 0.10 feet, respectively. Free product recovery should continue at the site
until free product is no longer present.
5.0 NATURAL ATTENUATION / NATURAL SOURCE ZONE DEPLETION STATUS
Free product recovery is being conducted at the site using AFVR events. Due to the site being in the
active free product recovery phase, no natural attenuation monitoring plan is currently in place at the
site.
6.0 CONCLUSIONS
 On April 22, 2020, four additional Type II monitoring wells (MW-2 through MW-5) were installed
around the UST basin to delineate free product. Wells MW-2 through MW-4 were installed to
total depths of 35 feet with screened intervals of 20 feet.
 On April 22, 2020, five Type II monitoring wells (MW-1 through MW-5) were gauged, purged
and/or sampled. Free product was observed in monitoring well MW-1 and MW-3 with a free
product thickness of 0.64 feet and 0.03 feet, respectively; therefore, these wells were not

feet relative to an arbitrary datum of 100 feet. Ground water elevations in the Type II monitoring
wells ranged from 75.75 feet to 77.02 feet. Ground water flow was generally to the northeast
with a horizontal gradient of approximately 0.02 feet per foot.
 The MACs were below the concentrations of benzene, MTBE, TAA, p-isopropyltoluene, n-
propylbenzene, 1,2,4-trimethylbenzene, methyl chloride, methylene chloride, 1,2-

C9-C10 aromatics, C9-C18 aliphatics, and/or C11-C22 aromatics reported in the ground water
samples collected from MW-2, MW-4 and MW-5. Free product was found in MW-1 and MW-3.
None of the reported contaminant concentrations were above the GCLs.
 Based on this information, the risk classification for the site should remain intermediate risk. Past

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.
