Mid-Atlantic Project No.:R3705.0B
Dear Ms. Ward:
Mid-Atlantic Associates, Inc. is pleased to submit this Modified Limited Site Assessment
Report.
BACKGROUND
On October 7, 2020,a torn boot around the riser of the spill bucket for Tank #3
(6,000-gallon regular unleaded) underground storage tank (UST) was observed at the
Speedway Store #8276.The location of this facility is illustrated in the Topographic Site
Map included as Drawing 1.On the same day, a UST-17A form was filed with the North
Carolina Department of Environmental Quality (NCDEQ).
On October 9, 2020, a replacement boot was installed and the spill bucket was
hydro-tested with passing results. A UST-17B form was filed on October 12, 2020.
To determine if a release may have occurred to the environment, environmental
assessment activities were conducted, which included the installation of monitoring well
MW-1 near the spill bucket (Drawing 2).During borehole advancement associated
with well MW-1, soil samples were collected at depth intervals of 11-13, 13-15, and
15-17 below ground surface (BGS).Analytical results obtained from these soil samples
indicated detection of total petroleum hydrocarbons -gasoline range organics
(TPH-GRO) at levels below the North Carolina Department of Environmental Quality's
(NCDEQ's) Action Level of 50 mg/Kg.
After low concentrations were detected in the initial groundwater sample (February
10, 2021), negotiations with NCDEQ personnel resulted in the collection of additional
groundwater samples prior to performing a Limited Site Assessment. Groundwater
samples were subsequently collected from well MW-1 on March 3, 2021 and August
18, 2021.Sample results exhibited MTBE and benzene concentrations in excess of
the North Carolina Groundwater Quality (2L) Standards (NCGQS) but lower than the
respective Gross Contaminant Levels (GCLs). Since target compound concentrations
still exceeded the NCGQS, it was determined that the well should be sampled again and
a receptor survey should be completed. These activities were completed on January 20,
2022.
RECEPTOR SURVEY
Risk Classification
Three categories (high, intermediate and low) of risk posed by a discharge or release
at a site have been established under 15A NCAC 2L .0406. Sites classified as high risk
must be remediated to the North Carolina Groundwater Quality Standards (NCGQS),
or as closely thereto as economically and technologically feasible. Sites classified as
intermediate risk must be remediated to gross contamination levels (GCLs). GCLs are
defined as levels of groundwater contamination for any contaminant except ethylene
dibromide, benzene, and aliphatic and aromatic carbon fraction classes that exceed
50 percent of the solubility of the contaminant at 25 degrees Celsius or 1,000 times
the groundwater quality standard or interim standard, whichever is lower. For ethylene
dibromide and benzene, GCLs are established at 1,000 times the federal drinking water
standard set out in 40 CFR 141. Aliphatic and aromatic carbon fraction classes are
excluded from GCLs. A low risk classification means that no further assessment or
corrective action of groundwater is required.
In order for the State to classify the level of risk to human health and the environment
posed by a discharge or release at the site, Mid-Atlantic conducted a receptor survey of
the surrounding areas and completed a “Limited Site Assessment Risk Classification and
Land Use Form” (Appendix A). Information was collected regarding groundwater/ surface
water/vapor impacts, land use and other information outlined in 15A NCAC 2L .0406 and
summarized in the following section of the report.

Water Supply Well Survey
On January 20, 2022, Mid-Atlantic personnel performed an area reconnaissance survey
to determine the location of water-supply wells within a 1,500-foot radius search area of
the source area of the release. A visual survey was conducted to locate water meters
and well houses.
A water supply well inquiry letter was sent to the nearby property located at 2011
Westwood Avenue since "no trespassing" signs were present on the property.The
survey letter explained the purpose of the investigation and requested a return phone
call to Mid-Atlantic in the event that a water-supply well (either in-use or not in-use) was
located on the property. Mid-Atlantic did not receive a response from the property owner.
According to the City of Wilson, this property maintains a municipal water account.
No water-supply wells were identified within the 1,500 foot search radius from the source
area of the release. The search area is shown on Drawing 3.
Public Water Supply
According to Lynn Wilson with the City of Wilson (who supplies municipal water to the
area), the municipal water-supply system is available to all properties within the
500-foot radius search area of the source area of release,
Surface Water
According to the USGS topographic quadrangle map of Wilson, North Carolina (Drawing
1), the nearest surface water body is an intermittent, unnamed tributary
located approximately 500 feet west/southwest of the source area of release. [Note:
information available on NCDEQ's Surface Water Assessment Program website does
not appear to show a water body in this location.]. This unnamed tributary drains the
Bloomery Swamp, which drains to Contentnea Creek.
According to NCDEQ NC Surface Water Classifications website
(https://ncdenr.maps.arcgis.com), Bloomery Swamp is classified as a Class "WS-IV;
NSW"water body.A Class WS-IV is defined as waters used as sources of water supply
for drinking, culinary, or food processing purposes where a WS-I, II or III classification
is not feasible. These waters are also protected for Class C uses. WS-IV waters are
generally in moderately to highly developed watersheds or Protected Areas..The "NSW"
classification refers to Nutrient Sensitive Waters and is a supplemental classification
intended for waters needing additional nutrient management due to being subject to
excessive growth of microscopic or macroscopic vegetation.

Wellhead Protection Areas
According to Mr. Danny Edwards, Source Water Assessment and Wellhead Protection
Programs Manager, the subject site is not located within an approved wellhead
protection area.
Deep Aquifers in the Coastal Plain Physiographic Region
The subject site is located in the Coastal Plain physiographic region within the Yorktown
Formation. The shallow water table is typically present in the Pleistocene terrace
deposits in Wilson County. The underlying Yorktown Formation functions as a confining
unit, and therefore the greatest groundwater circulation typically occurs above the
Yorktown Formation in the shallow aquifer. Some leakage occurs through the Yorktown
and provides recharge to the lower Cretaceous Aquifer, saprolite, and bedrock aquifer.
The saprolite typically provides storage for the bedrock aquifer, where groundwater
will typically be present only in bedrock fractures ( M.D. Winner, Jr. (Ground-Water
Resources of Wilson County, North Carolina, 1976).
According to Winner, the most utilized aquifers for water-supply wells are the Cretaceous
Aquifer and the bedrock aquifer (whose water storage is mainly in the overlying
saprolite). Recharge to these lower aquifers occurs through the confining Yorktown
Formation from the overlying shallow aquifer. Based on these factors and that fact that
the aquifers do not appear to be used for a water supply in the area, the risk posed by
the release appears to be low.
Subsurface Structures
Subsurface structures were not identified during the site reconnaissance. The site
structure is slab-on-grade construction.
Land Use
The site is a petroleum retail facility and convenience store and is immediately
surrounded by undeveloped land to the west, commercial properties (across Westbrook
Avenue) to the north, commercial properties (across Forest Hills Road West) to the east,
and commercial properties to the south. Since it is open to the general public, children
will visit the property but only for short periods of time. The land use of the subject site is
not anticipated to change in the near future. The general land use in the area is a mixture
of commercial and residential, with the residential areas located mostly to the south and
southwest of the site. A map showing zoning of nearby properties is included as Drawing
4.

Property Owners and Occupants
According to Wilson County tax records, the property is owned by Amicus Investments
LLC and is occupied by the staff of the convenience store during operating hours.
Otherwise, the property has no permanent occupants. Adjacent property owners are
identified in the table and drawing provided in Appendix B.
SOIL AND GROUNDWATER ASSESSMENT
Soil samples collected during the Site Check did not exhibit TPH concentrations
exceeding regulatory action levels. Groundwater samples have been collected from well
MW-1 four times since its installation in January 2021. The results of the first three
sampling events have been submitted to NCDEQ. The laboratory report and chain of
custody record for the January 20, 2022 (fourth) sampling event are provided in Appendix
C and are summarized in Table 1.
SUMMARY, CONCLUSIONS AND RECOMMENDATIONS
Soil and groundwater assessment results are summarized as follows:
•Several petroleum-related fuel compounds were detected in groundwater
samples collected from well MW-1 at concentrations exceeding the NCGQS but
below the GCLs and;
•The soil samples collected during the Site Check did not exhibit TPH
concentrations exceeding regulatory action levels.
The receptor survey did not reveal sensitive receptors near the release. Based on these
results, the site appears to meet the criteria for "low risk." NCDEQ will assign the risk
classification for the site. If the site is classified as low risk, it should be eligible for
closure through recording of a Notice of Residual Petroleum with the property deed
and performing Public Notification. Since groundwater exceeds health-based cleanup
standards, the NRP should include a groundwater use restriction.

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.

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.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
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.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
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.
U Below Detectable Limits: Indicates that the analyte was not detected.
