2.EXECUTIVE SUMMARY
S&ME collected samples from water supply wells WSW-2, WSW-4, WSW-5, WSW-6,
and WSW-7. S&ME also collected samples from monitoring wells MW-1, MW-2,
MW-4, MW-5, and MW-6. Contrary to the proposal, groundwater samples were not
collected from monitoring wells MW-3 and recovery well RW-1 as free product was
present in the wells at the time of the site assessment.
Benzene, ethylene dibromide (EDB), 1,2-dichloroethane, and methyl tert-butyl ether
(MTBE) were detected in monitoring well MW-1 at concentrations that exceeded Gross
Contamination Levels (GCLs). Benzene was detected in the groundwater sample
collected from monitoring well MW-2 at a concentration that exceeded the respective 2L
Standard but did not exceed the GCL standard for benzene. 1,2-Dichloroethane was
detected in the groundwater sample collected from monitoring well MW-5 at a
concentration that exceeded the respective 2L Standard but did not exceed the GCLs
standard for 1,2-dichloroethane. Free product thicknesses of 0.02, feet 0.12 feet, 0.28
feet were measured in wells MW-1, MW-3, and RW-1, respectfully. No target volatile
organic compounds (VOCs) were detected in the water supply well samples or the
groundwater samples collected from monitoring wells MW-4 and MW-6

Based on the October sampling events, contaminant concentrations have
decreased slightly in MW-1, when compared to the previous data from February
2014.
The extent of free product appears to be limited to the area in the vicinity of MW-
1, MW-3, and RW-1. Free product was not detected in the site’s monitoring wells
in February 2014.

These services were completed as proposed; with the exception that no samples were
collected and no redox potential data was measured from monitoring wells MW-3 and
RW-1 due to the presence of free product in excess of 0.02 feet. No DO measurements
were collected from MW-1, MW-3, and RW-1 due to the presence of free product.
Samples were also not collected from water supply wells WSW-1 and WSW-3 due to
lack of electricity (WSW-1) and no permission (WSW-3).
4.SITE HISTORY AND CHARACTERIZATION
Petroleum impacts were confirmed during the removal of one 2,000- gallon gasoline and
one 500-gallon kerosene underground storage tanks (USTs) during February 1994, based
on the analytical results of soil samples collected during UST closure activities. Each
sample collected during closure activities were reported to contain total petroleum
hydrocarbons (TPH) with concentrations ranging from 42 parts per million (ppm) as
gasoline range organics to 25,000 ppm as gasoline and diesel range organics. Three
additional 500-gallon gasoline USTs were reportedly filled with concrete.The site is
currently in residential use.Figure 1 indicates the location of the site. Site photos are
attached in Appendix I.
The closed in-place USTs were removed during February 1997 along with 144 tons of
petroleum-impacted soil. Four of the six confirmation soil samples collected at the
horizontal or vertical extent of the soil excavation, representing two of the former UST
locations, ranged from 2,500 ppm to 13,000 ppm TPH as gasoline range organics.
During March and April 1997, ten soil samples were collected from 12 soil borings
performed to a depth of 24 feet below ground to assess the horizontal extent of impacts
from the release. TPH was not detected in the soil samples.
Groundwater monitoring wells MW-1 through MW-3 were installed on-site and were
first sampled during November 1996.
•Multiple VOCs were detected at concentrations greater than the corresponding 2L
Groundwater Quality Standards (2L) in groundwater samples collected in
monitoring well MW-2 during eight sampling events performed from 1996 until
2012.
•Benzene, EDB, 1,2-dichloroethane, and MTBE were detected in groundwater
samples collected from monitoring well MW-1 and MW-3 at concentrations
greater than the corresponding Gross Contaminant Levels (GCL) during sampling
events performed in 2005, 2009, 2010 and 2011.
•Free product was detected in monitoring wells MW-1 and MW-3 during sampling
events performed in 1996, 1998, 2003, 2004, 2008, and during June 2012.
On-site monitoring well MW-4 and off-site monitoring wells MW-5 through MW-11
were installed and were first sampled during April 1998.
•Multiple VOCs were detected at concentrations greater than the corresponding 2L
levels in groundwater samples collected from monitoring well MW-5 during 10
sampling events performed from 1998 until 2012, and in samples collected from
monitoring well MW-8 during eight events from 1998 until 2010. Monitoring
well MW-8 could not be located during the June 2012 sampling event.

•With few exceptions, VOCs were not detected in monitoring wells MW-4 and
MW-6 during the same monitoring events.
•VOCs were not detected in monitoring well MW-7 during 1998 and 2003;
however, benzene was reported at a concentration of 140 microgram per liter
(ug/L) in 2004. Monitoring well MW-7 could not be located during the 2005,
2008 or 2009 sampling events.
•Benzene was detected in monitoring well MW-9 during 1998 and in monitoring
well MW-10 during 2003, and 1, 2-Dichloroethane was detected in monitoring
well MW-11 in 1998, each at concentrations greater than their 2L levels.
Monitoring wells MW-9 and MW-11 could not be located during monitoring
events performed since 2003. Monitoring well MW-10 has not been located since
2005.
Well RW-1 was installed in the source area and was first sampled in June 2010.
Benzene, EDB, 1,2-dichloroethane and MTBE were detected in groundwater samples
collected from well RW-1 at concentrations greater than the corresponding GCLs during
June 2010, and free product was reported in well RW-1 during June 2012.
The Groundwater Monitoring Report provided by TerraQuest (June 28, 2012)
documented the presence of 12 sole source water supply wells located within 1,000 feet
of the source area, including on-site water supply well WSW-1, and off-site water supply
wells WSW-2 through WSW-11 and WSW-18. S&ME noted references to the prior
installation of a Point-of-Entry (POE) filtration system on water supply well WSW-1 (on
the site), including analytical results for WSW1-PRE POE and WSW1-POST POE from
September 15, 2011 until June 2012.
Additional corrective actions performed in response to the release include approximately
18 Aggressive Fluid/Vapor Extraction (AFVR) events from June 1997 until November
1998, and approximately six Mobile Multi-Phase Extraction (MMPE) events performed
from July 2001 until November 2003.
On February 25, 2015, S&ME collected water samples from monitoring wells MW-1,
MW-2, MW-3, MW-4, MW-5, MW-6, recovery well RW-1, and water supply wells
WSW-1, WSW-2, WSW-3, WSW-4, WSW-5, WSW-6, and WSW-7 for analysis of
VOCs by SM 6200B. Target analytes were detected at concentrations that exceeded the
respective GCL standards in monitoring wells MW-1, MW-3, and recovery well RW-1.
No target constituents were detected above the laboratory reporting limit from the samples
collected from monitor wells MW-2, MW-4, MW-5 and MW-6 and water supply well
samples WSW-1 through WSW-7.
The scope of services conducted for this report were performed in general accordance
with S&ME’s Proposal No. 43-1400903A, dated September 2, 2015 and as authorized by
NCDEQ’s Task Authorization No. 02, dated September 3, 2015 and within NCDEQ’s

2990), Public Works Direct with the Town of Yadkinville, North Carolina. According to
Mr. Williams, the nearest water line is located at the intersection of US Highway 21 and
Old U.S. Highway 421, approximately 1.75 miles north of the subject property. The
water line is owned by Yadkin County and the water is supplied by the Town of
Jonesville.
5.CURRENT SITE ASSESSMENT INFORMATION
5.1 Current Liquid Levels
On October 3, 2015, S&ME was on-site to gauge depth-to-water and collect groundwater
samples from monitoring wells MW-1, MW-2, MW-4, MW-5, and MW-6. The
approximate location of the monitoring wells are depicted on Figure 3.
Based on the groundwater elevation, the shallow groundwater appears to flow generally
to the east. This is illustrated in the Groundwater Occurrence and Flow Direction Map
(Figure 4). The water level measurements collected on October 3, 2015 are summarized
in Table 4.
Groundwater Monitoring Report, Williams Grocery. #15063 S&ME Project No. 4305-14-239A
2425 US Highway 21, Hamptonville, North Carolina February 17, 2016

Free product was detected in monitoring wells MW-1, MW-3, and RW-1. A sample was
collected from MW-1 since the amount of free product was considered acceptable for
sampling. However, no sample was taken from monitoring wells MW-3 and RW-1 due
to free product exceeding a thickness of 0.02 ft.
5.2 Groundwater Monitoring Events
After measuring the depth-to-water, S&ME personnel purged approximately three well
volumes from each monitoring well with a disposable polyethylene bailer. After
completing the well purging, S&ME personnel collected groundwater samples. The
groundwater samples were placed in laboratory-supplied containers, stored in a cooler
with ice, and shipped under chain-of-custody procedures to Pace Analytical Services, Inc.
(Pace) for laboratory analysis. The groundwater samples were analyzed for VOCs by SM
6200B and for natural attenuation parameters including DO (field tested), REDOX
potential, iron by EPA Method 6010, nitrate by EPA Method 353.2, sulfate by EPA
Method 300.0, and alkalinity by SM 2320B. The natural attenuation analyses are
discussed further in section 4.4. Field sampling data records are included in Appendix
II.
On October 3, 2015, S&ME collected samples from water supply wells WSW-4, WSW-
5, and WSW-6. On October 19, 2015 S&ME returned to sample water supply wells
WSW-2 and WSW-7. The owner of supply well WSW-3 did not grant permission for
S&ME to sample and the property associated with WSW-1 had no electricity. Therefore,
samples were not collected from water supply wells WSW-1 and WSW-3.
The water supply well locations are depicted on Figure 2. Each well was purged for at
least 15 minutes prior to sampling. The groundwater samples were placed in laboratory-
supplied containers, stored in a cooler with ice, and shipped under chain-of-custody
procedures to Pace for laboratory analysis of VOCs by SM 6200B. Copies of the water
supply well sampling field forms are included in Appendix II
5.3 Summary of Groundwater and Free Product Assessment Information
Free product was measured in monitoring wells MW-1, MW-3, and RW-1 at thicknesses
of 0.02 feet, 0.28 feet, and 0.12 feet respectfully.
The groundwater analytical results from the monitoring well MW-1 indicated
concentrations of benzene, EDB, 1,2-dichloroethane, and MTBE greater than the
corresponding GCLs. The estimated extent of contaminants dissolved in groundwater are
depicted in Figure 5,Figure 6,Figure 7, and Figure 8, respectively. Target analytes
including but not limited to, , ethylbenzene, toluene, 1,2,4-trimethylbenzene, 1,3,5-
trimethlybenzene, and total xylenes were detected in monitoring wells MW-1 and/or
MW-3 at concentrations greater than the corresponding 2L Standards, but less than the
GCLs. 1,2-Dichloroethane was detected in the groundwater sample collected monitoring
well MW-5 at a concentration that exceeded 2L standard but not the GCL for 1,2-
dichloroethane. No target VOCs were identified above the method detection limits in
groundwater samples collected from monitoring wells MW-4 and MW-6.

The monitoring well analytical results compared to the current NCDEQ regulatory
standards are included on Table 5A and Table 5B. A copy of the laboratory report is
included in Appendix III.
The water supply well sampling results are summarized in Table 6.No target analytes
were detected in the water samples at concentrations that exceeded the respective
laboratory reporting limits.
5.4 Natural Attenuation Indicator Discussion
5.4.1 General
Natural attenuation takes places by utilizing natural processes to reduce or attenuate
contamination in soil and groundwater. It is possible for a wide variety of hydrocarbons
dissolved in groundwater to naturally biodegrade in the presence of indigenous microbes.
Natural attenuation can be demonstrated by comparing indicator parameters to specific
hydrocarbon concentrations in the subsurface. For example, a relative decrease in certain
indicators such as DO, REDOX potential, nitrate, or sulfate in groundwater samples
obtained with elevated concentration of petroleum contaminants may indicate the that
natural attenuation of the petroleum contaminants may be occurring. Additionally, a
relative increase in certain indicators such as ferrous iron or alkalinity in those same wells
with elevated petroleum contamination may also indicate natural attenuation.
5.4.2 Results
S&ME prepared graphs presenting petroleum contaminant concentrations as represented
by benzene in groundwater samples from wells MW-1, MW-2, MW-4, MW-5, and MW-
6 versus the concentration of the natural attenuation parameter data obtained from those
same wells. Wells MW-1, MW-2, MW-4, MW-5, MW-6 were selected for this
evaluation as the transect through these wells represents zones of contaminated and
unimpacted groundwater. Monitoring wells MW-2 and MW-4 represent the upgradient
portion of the plume; while, monitoring wells MW-5 and MW-6 represent the
downgradient portion of the plume. Well MW-1 is located within the source area. The
graphs are included in Appendix IV. The natural attenuation data is summarized in
Table 7.
The following trends or relationships were observed by reviewing the graphs:
•DO: Increase in concentration with decreased concentration of benzene;
•Ferrous Iron:Increase in concentration with decrease in benzene concentration;
•Nitrate:Potential decrease in concentration with increasing benzene
concentrations;
•REDOX Potential:No obvious trend was noted;
•Alkalinity:No obvious trend was noted.
After reviewing the attenuation indicator parameters and their respective graphs, not
enough information was presented to verify or disprove that natural attenuation is taking
place beneath the surface.

5.5 Regional and Site Geology and Hydrogeology
5.5.1 Soil and Bedrock
Soils underlying the site are characterized as Clifford sandy clay loam (two to six percent
slopes) well drained and low frequency of flooding. According to the 1985 USGS
Geologic Map of North Carolina, the site is underlain by the Inner Piedmont Belt.
Bedrock in this area consists of metamorphosed Granite rock characterized as
equigranular to megacrystic, foliated to massive, which also includes Toluca Granite.
5.5.2 Hydrogeology
Based upon measurements collected on October 3, 2015 by S&ME, groundwater at the
site appears to flow generally to the east with an average approximate gradient of 0.005
feet per foot.
5.6 Evaluation of Soil, Groundwater, and Free Product Assessment
Information
5.6.1 Current Extent and Severity of Contamination
Free product is present in the vicinity of wells MW-1, MW-3, and RW-1. The dissolved
concentrations of benzene, EDB, 1,2-dichloroethane, and MTBE present in the vicinity of
MW-1 at concentrations exceeding the respective GCL standards. The analytical data
suggests that the downgradient portion of the plume does not extend beyond monitoring
wells MW-5 and MW-6.
5.6.2 Cleanup Levels Achieved
•Soil (soil-to-groundwater maximum soil contaminant concentrations)No
•Groundwater (2L standard concentrations)No
•Free Product (0.01’)No
6.CONCLUSIONS 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 are 12 active drinking water supply wells within 1000 feet of the
source area, and an additional six active drinking water supply wells
located between 1,000 and 1,500 feet of the source area.
b.Five (5) active water supply wells are located within 500 feet of the source
area. No target compounds were detected in the samples collected from
water supply wells WSW-2, WSW-4, WSW-5, WSW-6, and WSW-7.
The nearest downgradient water supply wells is identified as WSW-4 and
is located 820 feet from the source area.

c.Contaminant concentrations for select VOCs exceed the 2L Standards and
GCLs based on analysis of groundwater samples collected from
monitoring well MW-1 on October 3, 2015.
2.No Surface water bodies were located within 1,500 feet of the source area
3.Water supply wells are the only source of water in the area. Municipal water is
not currently available to the properties in the site vicinity.
4.Free Product was encountered in monitoring Wells MW-1, MW-3, and RW-1 at
thicknesses of 0.02 feet, 0.28 feet, and 0.12 feet, respectively.
5.The natural attenuation data collected from select monitoring wells did not
confirm that natural attenuation of the site’s groundwater was occurring.
Based on the above, the following recommendations are presented:
1.Sample monitoring wells on a periodic basis and to document the migration of the
contaminant plume.
2.Consider collecting natural attenuation data during the next scheduled
groundwater sampling event to further evaluate the site for evidence of natural
attenuation.
3.Sample the active water supply wells within 500 feet of the source area on a
periodic basis.
4.Consider “hot spot” remediation to reduce the dissolved constituent
concentrations and free product in the vicinity of MW-1, MW-3, and RW-1.
