2.0 Executive Summary
On October 10, 2019 S&ME was on site to observe the installation of monitoring well MW-6 by Environmental
Drilling & Probing Services (EDPS), LLC at the Former Evan’s Grocery site. On November 6, 2019 S&ME Personnel
mobilized to the site and collected a groundwater sample from MW-6 and collected water levels and field
measurements from monitoring wells MW-1, MW-2, MW-3, MW-4 and MW-5. The laboratory analytical results
reported multiple constituents present in monitoring well MW-6 at concentrations greater than the 2L Standard:
North Carolina Groundwater Quality Standards: 15A NCAC 2L.0202 and are summarized in the table below.
Contaminant 2L Standard (µg/L) Concentration
(µg/L) Well ID
Benzene 1 190 MW-6
Isopropylbenzene 70 89 MW-6
Methyl tert-butyl ether 20 84 MW-6
Naphthalene 6 320 MW-6
n-Propylbenzene 70 150 MW-6
Xylenes, total 500 1,600 MW-6
1,2,4-Trimethylbenzene 400 1,000 MW-6

 S&ME did not measure free product in any of the monitoring wells (MW-1 through MW-6) on November
6, 2019. Free product has not previously been reported in these monitoring wells.

 A receptor survey was not completed during this sampling event. Based on the historical data, there are
six active drinking water supply wells (WSW-1, WSW-2, WSW-5, WSW-7, WSW-8 and WSW-10) located
within 1,000 feet of the source area. There are no inactive water supply wells, no irrigation wells, and one
active water supply well located between 0 and 500 feet of the source area; there are five active water
supply wells between 500 and 1,000 feet of the source area. Based on the most recent groundwater flow
at the site water supply well WSW-1 is located downgradient of the site and has the potential to be
impacted by the petroleum release. However, we have been unable to gain access from the property
owner to sample the well. We have made multiple attempts since 2011 to gain access to the water supply
well.

 To achieve incident closure, two options are presented:
1. Connect water supply wells located within 1,000 feet of the site to a municipal water source
(municipal water is not available to the site and surrounding properties) – abandoning the water
supply wells located within 250 feet of the source area, or
2. Reduce the level of petroleum constituents to less than the 2L Standard.

 According to the 1985 USGS Geologic Map of the North Carolina, the site is underlain by the Carolina
Slate Belt of the Piedmont Physiographic Province. Bedrock in this area is metamudstone and meta-
argillite, which is characterized as part of the Cid Formation, which is thin to thick bedded and having
bedding plane and axial-planar cleavage common. It is also interbedded with metasandstone,
metaconglomerate, and metavolcanic rock.

 Based upon data collected on November 6, 2019, depth to groundwater measurements at the onsite
monitoring wells ranged from 24.50 feet below top of casing (ft-BTOC) in monitoring well MW-4 to
31.61 ft-BTOC in monitoring well MW-6. Based upon data collected from the previous monitoring
event in July of 2019 groundwater levels were approximately 16.05 to 15.2 feet lower in MW-4 and
MW-1 respectively.
Based upon measurements collected on November 6, 2019, groundwater flow is to the northeast, and west. A site
map is provided as Figure 2 and the locations of water supply wells are provided as Figure 4.

5.0 Current Site Assessment Information
5.1 Monitoring Well Installation
On October 10, 2019 S&ME personnel mobilized to the site to oversee installation of monitoring well MW-6 by
Environmental Drilling & Probing Services (EDPS), LLC. The locations of the existing monitor wells and monitoring
well MW-6 is shown in Figure 2. The signed well construction record by EDPS is included in Appendix IV along
with the boring log completed by S&ME personnel.
5.2 Groundwater Monitoring Event
On November 6, 2019 S&ME personnel mobilized to the site and collected a groundwater sample from
monitoring well MW-6 and collected water levels and field measurements from monitoring wells MW-1, MW-2,
MW-3, MW-4 and MW-5. After measuring the depth-to-water of monitoring well MW-6, S&ME personnel purged
monitoring well MW-6 with a disposable polyethylene bailer by evacuating at least three well volumes. The field
parameters (pH, specific conductivity, and temperature) were collected at the well casing volume and recorded on
groundwater sampling field forms, which are located in Appendix IV. Site photographs are included in Appendix
III.
After completing the well purging, S&ME personnel collected a groundwater sample from monitoring well MW-6
and a field blank. Upon review of the data (see below), it was discovered that the groundwater sample collected
from monitoring well MW-6 was mislabeled in the field as the field blank (FB) and the field blank was labeled as
the sample collected from monitoring well MW-6. The groundwater samples were placed in laboratory-supplied
containers, stored in a cooler with ice, and shipped under chain-of-custody procedures to Con-Test Analytical
Laboratory (Con-Test), a North Carolina certified laboratory for laboratory analysis. The groundwater samples
were analyzed for volatile organic compounds (VOCs) by Standard Method 6200B. The laboratory analytical
results reported multiple constituents present in monitoring well MW-6 at concentrations greater than the 2L
Standard: North Carolina Groundwater Quality Standards: 15A NCAC 2L.0202. Results are shown in Table 4 and
pictured in Figure 5.
The depth-to-water for the monitoring wells ranged from 31.61 feet below top of casing (ft.-BTOC) in monitoring
well MW-6 to 24.50 ft.-BTOC in monitoring well MW-4. The depth to groundwater measurements and
groundwater elevations are provided in Table 3.
5.2.1 Soil and Bedrock
Soils underlying the site are the Tarrus gravelly silt loam, which are characterized as having two to eight percent
slopes. According to the 1985 USGS Geologic Map of the North Carolina, the site is underlain by the Carolina
Slate Belt of the Piedmont Physiographic Province. Bedrock in this area is metamudstone and meta-argillite,
which is characterized as part of the Cid Formation, which is thin to thick bedded and having bedding plane and
axial-planar cleavage common. It is also interbedded with metasandstone, metaconglomerate, and metavolcanic
rock.
5.2.2 Hydrogeology
S&ME calculated the groundwater elevations for the monitor wells gauged using the depth-to-water
measurements collected on November 6, 2019 and the relative top of casing elevations. The groundwater

January 3, 2020 8
elevations were used to prepare a groundwater elevation map (Figure 3), which indicates that the groundwater
flows to the northeast and to the west from monitoring well MW-1. However, in July 2019, groundwater at the
site was calculated to flow to the east, away from a ridge in the vicinity of MW-3. S&ME calculated the average
gradient as approximately 0.098 feet per foot. The change in gradient and groundwater flow since July 2019 may
be attributable to the addition of monitoring well MW-6 and its low groundwater elevation measured during this
monitoring event, in addition to normal fluctuating water levels that occur seasonally.
5.2.3 Current Extent and Severity of Contamination
No free product has been detected in the monitoring wells at the site. Multiple dissolved phase petroleum
constituents in monitor well MW-6 exceed the 2L Standard. No groundwater samples were collected from
monitoring wells MW-1, MW-2, MW-3, MW-4 or MW-5 so the severity of contamination in the vicinity cannot be
spoken to for the current monitoring event. However, historical dissolved contaminant levels indicate
contamination exists at its highest levels near monitoring well MW-1. With the addition of monitoring well MW-6
and the lab results provided during this monitoring event it can be assumed that contamination is likely traveling
west from the vicinity of monitoring well MW-1 with the direction of groundwater flow towards monitoring well
MW-6. Additionally, a groundwater contaminant plume has not been delineated for this monitoring event due to
the lack of data.

5.2.4 Cleanup Levels Achieved
 Soil (soil-to-groundwater maximum soil contaminant concentrations) Unknown
 Groundwater (2L standard concentrations) No
 Free Product - Free product has not been measured at the site. Yes

6.0 Conclusion and Recommendations
Based on the current and historical assessment information for the site, the following conclusions are presented:

1. The UST Incident meets the following conditions for a High Risk classification:
A. There is one active drinking water supply well within 250 feet of the source area, and four additional
active water supply wells located between 250 and 1,000 feet of the source area. Municipal water is
not available to the area surrounding the site. Based on the most recent groundwater flow at the site
water supply well WSW-1 is located downgradient of the site and has the potential to be impacted by
the petroleum release. However, we have been unable to gain access from the property owner to
sample the well. We have made multiple attempts since 2011 to gain access to the water supply well.
B. Historically contaminant levels in the groundwater exceed the 2L Standards in the previous sampling
event conducted on June 11, 2019.
2. The extent of groundwater contamination at the site is not defined to the south and west.
Based on the above, the following recommendations are presented:

1. Consider collecting natural attenuation data during the next scheduled groundwater sampling event to
further evaluate the site for evidence of natural attenuation.
2. Due to lower water levels in the late summer/fall months, S&ME suggests sampling the wells again in
April 2020 when the water levels should be higher.
3. Attempt to gain access to the adjoining property to the south to collect a groundwater sample from water
supply well WSW-1.

USTs were removed from the site in March 1996. Indications of contaminated soil were reportedly observed near the
former dispenser island. Analytical results for soil samples collected during closure of the UST system identified
petroleum hydrocarbon concentrations greater than the NCDENR action levels in 1998.

*QC result is outside of established limits.
Wide recovery limits established for difficult compound.
Wide RPD limits established for difficult compound.
#Data exceeded client recommended or regulatory level
Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the
calculation which have not been rounded.
No results have been blank subtracted unless specified in the case narrative section.
FLAG/QUALIFIER SUMMARY
Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
J
Laboratory fortified blank/laboratory control sample recovery and duplicate recoveries outside of control limits.
Data validation is not affected since all results are "not detected" for associated samples in this batch and bias is
on the high side.
L-02
Laboratory fortified blank/laboratory control sample recovery and duplicate recovery are outside of control limits.
Reported value for this compound is likely to be biased on the high side.
L-06
Either laboratory fortified blank/laboratory control sample or duplicate recovery is outside of control limits, but
