n Water samples collected from wells WSW-1 and WSW-5 did not contain petroleum
constituents at concentrations above the laboratory detection limits.Non-petroleum
constituents bromodichloromethane and chloroform were detected in the samples
collected from water supply well WSW-1.These constituents are by-products of the
disinfection process for potable water, therefore, Terracon concludes that the spigot
from which the sample was collected is connected to municipal water.
n Terracon was unable to sample water supply wells WSW-2, WSW-3,or WSW-4 due
to no response from the property owners.
n According to the owners of water supply wells WSW-9 and WSW-10, the wells are
no longer in use,but the property owners are not interested in abandoning the wells
at this time.
C.SITE HISTORY AND CHARACTERIZATION
The purpose of this report is to present the current status of the groundwater quality at the
Former Village Mart site.Terracon completed this report to summarize the findings of assessment
activities performed on April 20 and June 10, 2019 at the former gasoline station located at 2260
Old Salisbury Road in Winston-Salem,Forsyth County,North Carolina(Exhibit 1).This Groundwater
Monitoring Report was prepared for the site in response to a request by Mr. Herb Berger,Incident
Manager with the NCDEQ Division of Waste Management, State Lead Program.
The Groundwater Monitoring Report was prepared in general accordance with the 15A NCAC 2L
.0115 regulations and the NCDEQ UST Section Guidelines for Assessmentand CorrectiveActionfor
UST Releases,dated July15,2008,revised December 2013,under the supervisionof Mr.Zachary R.
Tidmore, a North Carolina registered Professional Geologist (North Carolina License No.2611).
C.1 Site Setting
The approximately 0.48-acre site is located in a residential and commercial area and is currently
occupied by a motorcycle repair shop in Winston-Salem, Forsyth County, North Carolina. The
motorcycle repair shop formerly operated two 2,000-gallon gasoline underground storage tanks
(USTs), one 550-gallon kerosene UST, one 550-gallon used motor oil UST, and one 270-gallon
kerosene UST from the 1950s until July 2007.The former USTs and dispenser islands appear to
have been located on the northwest portion of the site, along Old Salisbury Road.
C.2 Release Summary
On July 25, 2007, GeoScience Technology, P.A. supervised the removal of the five former USTs at
the site. Closure soil samples collected from beneath the base of the former 270-gallon kerosene
UST (UST-3), former 550-gallon kerosene UST (UST-4), and dispenser island DP-1 contained total
petroleum hydrocarbons -diesel range organics (TPH-DRO) and TPH-gasoline range organics
(TPH-GRO) at concentrations exceeding the respective NCDEQ Guideline Action Levels in effect at

that time of 10 milligrams per kilogram (mg/kg).Subsequently, Agra Environmental, Inc. (Agra)
installed two groundwater monitoring wells (MW-1 and MW-2) to depths of 38 feet bgs and 40 feet
bgs, respectively. Monitoring well MW-1 was advanced through the tank pit of former UST-3 and
well MW-2 was advanced through the tank pit of former UST-4 and near DP-1. Two soil samples
were collected at depths of 10 feet bgs and 20 feet bgs from each monitoring well boring. The soil
samples were analyzed for VOCs by USEPA Method 8260 including IPE and MTBE, and semi-
volatile organic compounds (SVOCs) by USEPA Method 8270. Additionally, the soil samples
collected from 10 feet bgs from each boring were analyzed for volatile petroleum hydrocarbons
(VPH) and extractable petroleum hydrocarbons (EPH) by the MADEP Methods. Analytical results
indicated the presence of several petroleum constituents at concentrations exceeding the respective
laboratory reporting limits but below the NCDEQ Soil-to-Groundwater Maximum Soil Contaminant
Concentrations (MSCCs) in soil samples collected from both borings. Soil samples collected from
the well MW-1 boring at a depth of 10 feet bgs contained C9-C22 aromatics at a concentration
exceeding its Soil-to-Groundwater MSCC but below its NCDEQ Residential Cleanup Standard.
C.3 Previous Investigations
Agra collected groundwater samples from monitoring wells MW-1 and MW-2 on July 17, 2009 and
analyzed them for VOCs by USEPA Method 8260, SVOCs by USEPA Method 8270, VPH and EPH
by the MADEP Method, and lead by USEPA Method 3030C. Groundwater analytical results
identified the presence of several petroleum constituents at concentrations exceeding the laboratory
reporting limits but below the 2L Standards.The groundwater samples from monitoring well MW-2
contained bromodichloromethane and C9-C22 aromatics at concentrations exceeding the 2L
Standards but below the NCDEQ Gross Contamination Limits (GCLs). Lead was detected in
groundwater samples from monitoring wells MW-1 and MW-2 at concentrations exceeding the 2L
Standard but below the GCL.
A second groundwater sampling event was conducted by Agra in November 2009.The groundwater
sample collected from monitoring well MW-1 was analyzed for lead by USEPA Method 3030C and
the sample from well MW-2 was analyzed for VOCs by USEPA Method 6200B, SVOCs by USEPA
Method 625, VPH and EPH by the MADEP Methods, and lead by USEPA Method 3030C. Analytical
results identified the presence of C11-C22 aromatics and tetrachloroethylene (PCE) at
concentrations exceeding the 2L Standards but below the GCLs in the groundwater sample
collected from well MW-2.
Agra collected an additional groundwater sample from well MW-2 on July 6, 2010 and analyzed it for
VOCs by USEPA Method 6200B, SVOCs by USEPA Method 610, and VPH and EPH by the
MADEP Methods. Monitoring well MW-1 was not sampled. Analytical results identified the presence
of PCE and MTBE at concentrations exceeding the laboratory reporting limits but below the 2L
Standards.

C.4 Water Supply Wells
Terracon completed a walking/driving reconnaissance in the site vicinity on April 20, 2018. Based on
our review of the prior receptor survey and information obtained from the site vicinity reconnaissance
and the Forsyth County GIS website,six water supply wells were identified within 500 feet of the site
and four wells were identified between 500 and 1,000 feet of the site.Water supply wells were not
identified beyond 1,000 feet of the site.A water line appears to have been constructed along Zeverly
Street since the prior receptor survey.Water supply well information is included in Table 1, and a
map showing water supply well locations is included as Exhibit 3.
D.ASSESSMENT INFORMATION
D.1 Groundwater Monitoring Well Construction
On April 30, 2019 Terracon mobilized to the site to install three two-inch diameter groundwater
monitoring wells (MW-3, MW-4, and MW-5) on the western site corner,northern site corner, and
south of the on-site building, respectively, using hollow-stem augers. Terracon encountered auger
refusal at approximately 10 bgs. Terracon remobilized to the site on June 6, 2019 to continue
advancement of the boreholes using air rotary drilling methods/tooling. Soil lithology was evaluated
from auger soil cuttings and air rotary blow-out. Lithology generally consisted of reddish-brown silty
sand and bedrock consisted of grey to black granite.Photoionization detector (PID) readings of the
soils were less than 0.1 parts per million (ppm). PID readings are included on the boring logs
attached in Appendix A.

The permanent Type II monitoring wells were installed in the boreholes as follows:
n Installation of 10 feet of two-inch diameter, 0.010-inch machine slotted PVC well screen with
a threaded bottom cap;
n Installation of two-inch, threaded, flush-joint PVC riser pipe to surface;
n Addition of pre-sieved 20/40 grade silica sand for annular sand pack around the well screen
from the bottom of the boring to approximately two feet above the top of the well screen;
n Addition of approximately two feet of hydrated bentonite chips on top of the sand pack;
n Grout remaining annulus above the bentonite seal to the land surface; and,
n Installation of a flush mount protective cover in a traffic-rated square concrete pad.
Following installation,the wells were developed, and a locking expansion plug was used to secure
and seal the top of each well casing.Top-of-casing elevations for monitoring wells MW-3, MW-4,
and MW-5 were measured by Terracon using a transit level. Drill cuttings were spread on-site. The
monitoring well construction details are summarized on Table 2. The boring logs are presented in
Appendix A, and the well construction records are appended to the boring logs. The approximate
locations of the monitoring wells are depicted on Exhibit 2.
D.2 Sampling Activities
Terracon mobilized to the site on June 10, 2019 to collect groundwater samples from monitoring
wells MW-1,MW-2,MW-3,MW-4, and MW-5 and collect water samples from water supply wells
WSW-1, WSW-2, WSW-3, WSW-4, WSW-5, and WSW-10. The approximate locations of the wells
are shown on the Site Map (Exhibit 2). Photographs and field notes are included in Appendix B.
D.2.2 Groundwater Sampling Activities
Prior to sample collection,Terracon gauged the depth to groundwater in the monitoring wells.Depth
to groundwater ranged from 24.26 feet below ground surface (bgs) to 25.84 feet bgs.Current and
historical groundwater elevation measurements are provided in Table 2.Based on June 2019
groundwater elevations,shallow groundwater is estimated to flow towards the south-southeast
(Exhibit 4).
The monitoring wells were purged with a peristaltic pump using low flow sampling techniques (i.e.,
<200 milliliters per minute) prior to sampling. The following parameters were measured during
purging: pH, temperature, oxidation reduction potential (ORP), dissolved oxygen (DO), and
conductivity. Purge water from the monitoring wells was disposed in accordance with NCDEQ
guidelines.The groundwater samples were placed into laboratory-supplied glassware, labeled, and
stored in an ice-packed cooler. The groundwater samples, along with chain-of-custody
documentation, were delivered to Pace National Center for Testing & Innovation (Pace)in Mount
Juliet, Tennessee for analysis of VOCs by USEPA Method 6200B including MTBE, IPE and EDB.

D.2.3 Water Supply Well Sampling Activities
Water supply wells WSW-2, WSW-3,and WSW-4 were not sampled because a response was not
received from the property owners regarding permission to sample the wells.According to the
owners of water supply wells WSW-9 and WSW-10, the wells are no longer in use but the property
owners are not interested in abandoning the wells at this time. Samples were collected from water
spigots indicated by the property owners of wells WSW-1 and WSW-5.
Prior to sampling, water was allowed to flow from owner-designated spigots for approximately 15
minutes in an effort to purge the lines of stagnant water. Flow from the spigots was reduced when
the samples were collected directly into laboratory supplied containers.
The water supply well samples were placed in laboratory-supplied glassware, labeled and stored in
an ice-packed cooler. The samples, along with chain-of-custody documentation, were delivered to
Pace for analysis of VOCs by USEPA Method 6200B including MTBE, EDB, and IPE.
D.2.4 Analytical Results
LNAPL and petroleum constituents exceeding the GCLs were not detected in the monitoring wells.
Based on the laboratory analytical reports,six petroleum constituents (benzene, ethylbenzene,
methyl isobutyl ketone,1,2,4-trimethylbenzene, toluene, and total xylenes)were identified at
concentrations above 2L Standards in monitoring wells MW-1,MW-2,MW-4,and/or MW-5.Non-
petroleum constituents bromodichloromethane and chloroform were detected in the sample
collected from water supply well WSW-1.
Current and historical groundwater analytical results are summarized on Table 3,and the current
results are depicted on Exhibit 5. Field notes are presented in Appendix B,and a copy of the
laboratory analytical report is provided in Appendix C.
E.CONCLUSIONS AND RECOMMENDATIONS
Based on information obtained during the completion of these assessment activities, Terracon
provides the following findings and conclusions.
n LNAPL was not detected in the monitoring wells, and petroleum constituents were
not detected at concentrations exceeding the GCLs.
n Six petroleum constituents were identified at concentrations exceeding the 2L
Standards in monitoring wells MW-1 through MW-5.Water samples collected from
wells WSW-1 and WSW-5 did not contain petroleum constituents at concentrations
above the laboratory detection limits.Non-petroleum constituents
bromodichloromethane and chloroform were detected in the samples collected from
water supply well WSW-1. These constituents are often by-products of the
disinfection process for potable water;therefore, Terracon concludes that the spigot

from which the sample was collected is connected to municipal water.
n Terracon was unable to sample water supply wells WSW-2, WSW-3,or WSW-4 due
to no response from the property owners.
n According to the owners of water supply wells WSW-9 and WSW-10, the wells are
no longer in use,but the property owners are not interested in abandoning the wells
at this time.
Based on the data presented in this Monitoring report, Terracon recommends the following activities
be completed at the site:
n Groundwater monitoring wells (MW-1 through MW-5) should be sampled annually to
evaluate the status of impacts by petroleum constituents.
n Attempt to abandon water supply wells WSW-1 through WSW-4.
n Terracon confirmed that municipal water is available along Zeverly Street. Terracon
recommends attempting to abandon water supply wells WSW-6, WSW-7, and
WSW-8 and connect the residences to municipal water.

ONE LAB. NATIONWIDE.CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

ONE LAB. NATIONWIDE.GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Abbreviations and Definitions
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
J The identification of the analyte is acceptable; the reported value is an estimate.
J4 The associated batch QC was outside the established quality control range for accuracy.
