Sneads Ferry, North Carolina
WSP Project No. 6228 22 0250
Dear Mr. Bailey:
WSP Environment & Infrastructure, Inc. (WSP) is pleased to submit this report for a Phase II
Environmental Site Assessment at the former C-store located at 980 Hwy 210 in Sneads Ferry,
North Carolina (Figure 1). This project was conducted in response to your request for proposal during
our conversation on July 8 and July 11, 2022, and our proposal dated September 18, 2022. The areas of
concern for the assessment are associated with four petroleum underground storage tanks (UST’s)
on the subject property. This report includes our understanding of the project information, scope of
services, results and our conclusions and recommendations.
BACKGROUND
WSP understands that the site was a former C-Store known as Scotchman 231 and is located at
980 Hwy 210 in Sneads Ferry, North Carolina. The NCDEQ recently had the site listed as an active
UST commercial gasoline UST facility. Based on information provided by the NCDEQ, the UST
system was put into temporary inactive status by Scotchman in 2011. That status appears to have
changed recently. Reviews of aerial photography and information provided suggests that the
fueling operation at the site has not been operational for at least 8 years and the dispensers were
removed prior to 2019. Based on our review of the site there are currently four UST’s on the site.
It also appears that the underground delivery lines are still present from the dispenser to the
UST’s. WSP could find no record of soil or groundwater sampling in the web based NCDEQ files
for the site.
PROPOSED SCOPE OF SERVICES
WSP drilled 5 geoprobe borings at the site to assess if there have been releases of petroleum fuels
associated with the UST fueling system. This included borings around the former fuel dispensers
and borings around the UST’s. The work consisted of the following tasks.
• Prior to drilling, each of the boring locations was cleared for underground utilities using a
ground penetrating radar survey provided by a private utility locating service. WSP also called
One-Call public service to conduct a utility location survey in the right of ways.
• The geoprobe borings were advanced to a depth of approximately 10 to 12 feet below ground
surface (BGS).
• Soil samples from each boring were logged and screened in the field by a geologist.
• Based on field visual observations such as staining, three soil samples were selected from
above the water table and submitted to a certified laboratory for analysis of TPH-GRO and
TPH DRO (Method 8015 1700M).
• The sample exhibiting the highest evidence of contamination was selected for laboratory
analysis.
• Groundwater samples were collected from temporary geoprobe wells at three locations where
contamination was most evident.
• The groundwater samples were analyzed by the laboratory for VOC’s (Method 8260).
• The horizontal locations of the sampling points were determined with a GPS.
• Upon receipt of the lab analytical data, we have prepared this report addressing the sampling
and analysis results documenting the field activities and analytical lab results.
• A receptors survey was also completed per Bailey’s request on the site to determine the
availability of public water (ONWASA) and if properties within 500 feet were connected to
public water. This also included a check for water supply wells and surface waters within 1,500
feet of the subject site.
RECEPTORS SURVEY
WSP performed a receptor survey which included a visual site reconnaissance and review of
pertinent resources, to identify locations of water supply wells, public water supplies, surface
water, wellhead protection areas, and deep aquifers with respect to the Site. Recorded mapped
sources from the regional water authority ONWASA public works, the Soil and Water Conservation
Department, and available geographic information systems (GIS) data were reviewed to determine
the presence of water resources and land use within a 1,500-foot radius of the Site boundary.
The Site is in Sneads Ferry, Onslow County, North Carolina, and is within the Coastal Plain
physiographic and geologic province. The site is an area of surficial undifferentiated deposits of
fluvial sands, silts, clays, and gravel often grading upwards into fine sands and silty, clayey sands.
Typically, this area is underlain by limestones that may be used as an aquifer. Shallow wells and
deeper wells have been used in the area for potable water supply.
Topographically, the Site is located at an elevation of approximately 40 feet (NGVD). The general
topographic slope is towards the south. Based on site soil borings the depth to groundwater
appears to range from approximately 2-4 feet bgs. The direction of groundwater flow is expected
to be to the south which is relatively consistent with the topographic gradient.
The area of the site has potable water service supplied by the regional water authority known as
the ONWASA. WSP conducted a visual survey of the area within 500 and 1,500-feet of the subject
site. The area within the 1,500-foot radius is primarily used for commercial business. There is a
campground to the northeast with numerous campers connected to water and sewer. We could
not determine if these campers were connected to ONWASA or if they may be on a water well.
We observed that many of the businesses were connected to ONWASA potable water, and we did
not observe a water supply well within the search area.
We have communicated with ONWASA and sent them a list of the occupied properties within the
500-foot radius to the engineering department requesting identification of any properties or
businesses that were not on potable water supply. We are waiting for ONWASA’s response at the
time of this report.
Property Occupants and Land Use
The Sites is occupied by the closed C Store. The site was formerly used as an operational gasoline
station. Small businesses and undeveloped land occupy the land immediately south and
southwest and topographically downgradient of the subject site. Other adjacent properties consist
of commercial businesses and unoccupied.
Sensitive Land Use Features
WSP identified no water supply wells (WSW) within the 1,500-foot search radius of the subject
site. One surface water, a man-made stormwater pond, is located approximately 300 feet to the
southwest and is present within the 1,500-foot receptor radius. Land use features within the 1,500-
foot receptor radius include an active gas station at least two other closed gas stations located
north to northeast of the subject site. Most of the remaining land use is residential with the
campers to the northeast, commercial businesses, and undeveloped land. A public school is
located more than 1,500 feet to the south along Hwy 210.
Water Supply Wells
The Site and surrounding area are connected to the ONWASA water supply system and sanitary
sewer, according to Mr. Jay Williams of ONWASA Public Works. Based on reviews of water service
maps on the ONWASA website, there are water mains installed along Hwy 210 and 172 that
provides water to the businesses and residences throughout the area. ONWASA does not require
residences to connect to the system, which indicates that wells could still be used.
During the visual reconnaissance survey, WSP did not observe properties located within 1,500 feet
of the Site with private or public water supply wells
Public Water Supplies
According to the NCDEQ Public Water Supply Section (PWSS) Source Water Assessment Program
(SWAP) information system, no public water supplies appear to be within 1,500 feet of the site
boundary. ONWASA reportedly draws its public water supply from deep wells. None of these
public water supply wells are within 1,500 feet of the site.
Surface Water
The nearest surface water body is a man-made stormwater pond located approximately 300 feet to
the southwest of the site. WSP does not see risk to this water body from the subject site.
Well Head Protection Areas
According to the NCDEQ PWSS SWAP information system, there are no well head protection areas
as defined in 42 USC 300h-7(e) located within a 1,500-foot receptor radius of the site boundary.
Subsurface Structures
Subsurface utilities within the area appear to be limited to shallow phone, electric, and cable utility
lines, and municipal water utility pipes. It does not appear that these subsurface structures are
being impacted by the release.
BORINGS, SOIL AND GROUNDWATER SAMPLING
WSP oversaw Regional Probing Services in advancing five soil borings using a Geoprobe (Direct
Push Technology) Drill Rig to a total depth of 10 to 12 feet below ground surface (bgs). The
downhole drilling equipment was decontaminated prior to the start of each boring. WSP collected
continuous soil samples during the drilling process. The samples were logged by a WSP geologist.
The boring and sampling locations are shown on Figure 2. Drilling records and boring logs are in
Appendix A.
Soil and groundwater samples were collected from three of the five borings based on visual and
olfactory indicators of potential presence of petroleum. The locations as shown on Figures 2 and
3 are SS1/TM-3, SS-5/TM-2 and SS-4/TM-1. The SS designates soils samples and TW designates
temporary well groundwater sample.
The three temporary wells were set at approximately 11 to 11.5 feet below ground. The temporary
wells were purged with a peristaltic pump and the groundwater was monitored in the field for
geochemical parameters including temperature, conductivity and pH using a field calibrated
meter. Once the geochemical parameters stabilized the groundwater samples were collected.
Groundwater samples were collected via dedicated tubing into laboratory-supplied containers,
chilled, and shipped to Pace Analytical Services, Inc., an NCDEQ-certified laboratory, under chain-
of-custody protocol. Purge water was discharged to the ground surface near each well.
Each groundwater sample was analyzed for VOCs by EPA Method 8260. Soil samples were
analyzed for total petroleum hydrocarbons (TPH) as gasoline and as diesel.
Soil and Groundwater Analytical Results
Soil and groundwater analytical results are provided in the laboratory analytical reports included
in Appendix B. Samples from two monitoring wells indicated petroleum impacts to groundwater.
Regulated compounds including benzene exceeded NC Groundwater Standards in TM-3.
TPH as gasoline was well above the NCDEQ action in the soil sample from SS-5 (3,080 mg/kg) and
below the action levels in soil samples SS-1 and SS-4. TPH as diesel exceeded the NCDEQ action
level at soil sample SS-5 (91.8 mg/kg) and soil sample SS-1 (73 mg/kg). There were no
exceedances in the soil samples from SS-4. The soil and groundwater sample analysis results
indicate a release of fuels to the subsurface at the site.
CONCLUSIONS AND RECOMMENDATIONS
WSP has completed this receptors survey and soil and groundwater assessment. Based on the
results of our assessment the following conclusions can be made.
• Groundwater samples from well TMW-3 exceeded NCDEQ Groundwater Standards for
benzene.
• Soil samples from two of the three sampling locations exceeded NCDEQ Total Petroleum
Hydrocarbon Action levels for soils.
• The investigation indicates a significant release of petroleum from the UST’s has occurred.
Once notified about this release the NCDEQ will request additional assessment of
groundwater and soil at the site known as a Phase I Limited Site Assessment.
• The potential impact to receptors from this release appear to be minimal based on our
sensitive receptors review. There is one small stormwater pond located nearby but it would
appear unlikely that the water in the pond would be impacted from this release from the
UST system. We did not locate any water supply wells during our survey of the area. The
area is connected to the ONWASSA public water system
We appreciate the opportunity to provide our services. If you have any questions concerning these
services or schedule, please contact Chris Pruneau at (910) 231-2955.

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
(dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL Method Detection Limit.
MDL (dry)Method Detection Limit.
RDL Reported Detection Limit.
RDL (dry)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
C3 The reported concentration is an estimate. The continuing calibration standard associated with this data responded low.
Method sensitivity check is acceptable.
C4 The reported concentration is an estimate. The continuing calibration standard associated with this data responded low. Data is likely to show a low bias concerning the result.
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.
