SECTION B. EXECUTIVE SUMMARY 

1. Summary of Activities Associated with Current TA 

WithersRavenel, Inc. (WR) sampled the four monitoring wells associated with the site, Hunt’s 301 
Convenience Mart site located at 3671 US Highway 301 South in Fairmont, Robeson County, 
North Carolina, in association with task authorization (TA) TA‐01, under North Carolina 
Department of Environmental Quality (NCDEQ) Contract #N70522‐C.   

2. Groundwater and LNAPL Assessment Information 

Soil 
Soil samples were not collected as part of this TA. During the February 2022 underground storage 
tank (UST) removal activities, soil samples were collected from the UST basin and beneath the 
product lines and dispensers. Samples collected from beneath the UST components were analyzed 
for total petroleum hydrocarbons (TPH) gasoline range organics (GRO) and TPH‐diesel range 
organics (DRO). Several of the soil samples indicated concentrations above the NCDEQ Action 
Levels for TPH‐GRO and TPH‐DRO. Over‐excavation samples indicated the presence of 
compounds in excess of the Soil‐to‐Groundwater Maximum Soil Contaminant Concentrations 
(MSCCs). None of the compounds exceeded the Residential MSCCs.  

Groundwater  
Groundwater samples were collected from monitoring wells MW‐1 through MW‐4 on March 8, 
2023, and analyzed for volatile organic compounds (VOCs) by Standard Method 6200B. 
Laboratory results indicated the following: 
 None of the compounds were present above the Gross Contamination Levels (GCLs). 
 Monitoring wells MW‐1, MW‐2 and MW‐3 contained several compounds above the North 
Carolina Groundwater Quality Standards (2L Standards). 
 Monitoring well MW‐4 contained p‐isopropyltoluene above the 2L Standard. 

Light Non‐Aqueous Phase Liquid (LNAPL) 
No LNAPL was measured in MW‐1 through MW‐4 when these wells were gauged on March 8, 
2023, nor has LNAPL historically been identified at the site.   

3.       Receptor Information 

Municipal water is available to the local area from the Robeson County Water Department. One 
water supply well (the on‐site inactive well, WSW‐1) was identified within 500 feet of the subject 
property. One additional well, WSW‐2, was observed approximately 1,450 feet upgradient from 
the site and this property is connected to the municipal water supply.  No wellhead protection 
areas were identified within 1,500 feet of the subject property.

4. Remediation Activities 

No remedial actions have been completed at the facility, with the exception of the removal of the 
UST system in February 2022 during which a total of 129.44 tons of petroleum‐impacted soil was 
excavated and disposed of off‐site.   

5. Recommendations 

Based on the results of assessment and monitoring activities conducted at the site in association 
with this TA, WR recommends the following: 
 Abandon the inactive on‐site water supply well WSW‐1. 
 Placement of a Notice of Residual Petroleum (NRP) with groundwater restrictions on the 
site property. 
 Consider site closure for this incident. 

SECTION C. SITE HISTORY AND CHARACTERIZATION 

The following information summarizes the site history and characterization.   

1. UST Information 

The site is located at 3671 US Highway 301 S in Fairmont, Robeson County, NC (Figure 1). One 
4,000‐gallon and one 8,000‐gallon capacity gasoline USTs were removed from the subsurface of 
the site on February 22, 2022. Before their removal, 916 gallons of liquids were removed from the 
USTs. According to the NCDEQ UST‐10B report, the USTs were last used in September 2008. 
Information regarding the UST system is included on Table B‐1. Soil analytical results obtained 
during the tank closure activities are included in Table B‐3. The location of the former UST system 
is shown on Figure 2. 

2.       Description of Release/General Assessment History 

Analytical results for soil samples collected during the February 2022 UST removal activities 
indicated TPH GRO and/or DRO at concentrations in excess of the NCDEQ Action Levels in seven 
samples of overburden soils, five of the side wall soil samples, and three of the fuel line samples 
(closest to USTs) from the gasoline UST excavation. With the exception of the closure of the UST 
system in February 2022, WR is not aware of any other releases or assessment activities on the 
subject property. 

3.  Brief Description of Site Characteristics 

The site is located in an agricultural and residential area in the town of Fairmont, which is in the 
southwest‐central portion of Robeson County. The property contains a one‐story wooden 
residential home which had a “For Sale” sign in front, a convenient store, and storage building 
which appeared to be in poor condition. Topography across the site is flat.

4.       Information on Receptors/Potential Receptors 

Municipal water is available to the local area except for along portions of Chicken Road, but to 
date, there are no water supply wells within 1,500 feet along this road.  One water supply well 
(the on‐site inactive well, WSW‐1) was identified approximately 50 feet downgradient from the 
source area. No additional water supply wells were identified within 500 feet of the source area. 
One possible inactive or destroyed well was noted during the site reconnaissance approximately 
800 feet downgradient. However, the property owner indicated this property does not have a well 
and the Robeson County Water Department confirmed this property has an active municipal water 
account. One additional well, WSW‐2, was observed approximately 1,450 feet upgradient from 
the site and this property is connected to the municipal water supply.   

The NC SWAP website did not identify any community supply wells or wellhead protection areas 
within a 1,500‐radius of the site. 

Electrical power and phone services are delivered to the site and surrounding properties through 
pole‐mounted overhead lines.  No fiber optic lines were observed in the vicinity of the source area. 
Robeson County water lines are provided through buried services.  The water lines and identified 
water supply wells are shown on Figure 3. Information regarding the identified water supply wells 
is included in Table B‐5A. 

5.       Regional and Site Geology and Hydrology 
The site is located in the Coastal Plain Physiographic Province of North Carolina and situated in a 
location characterized by sedimentary rocks of the Black Creek Formation from the late Mesozoic. 
Materials mapped within the area of the site are described as: “Lignitic clay. Cross bedded sand 
and sand lenses.”   

Soils indexed by WR personnel during the installation of the four site monitoring wells included 
silty sand to approximately two feet below ground surface (ft‐BGS) followed by silts and grading 
to clay closer to 10 feet BGS. No bedrock was encountered in any of the four borings.  The borings 
were terminated in groundwater. 

Depths to groundwater ranged from 2.26 feet below top‐of‐casing (BTOC) in MW‐4 to 2.93 feet 
BTOC in MW‐1. Groundwater flow direction was generally to the west.  

SECTION D. GROUNDWATER SAMPLING – MARCH 2023 
On March 8, 2023, WR personnel gauged, purged, and sampled monitoring wells MW‐1 through 
MW‐4. The following paragraphs describe the sampling activities and associated laboratory 
analytical results.  

Groundwater Sampling Activities 
Prior to the purging and sampling of site monitoring wells as described below, WR personnel 
gauged the wells with an electronic oil‐water interface meter to determine the depth to LNAPL 
and groundwater at each well location.  During the performance of these activities, LNAPL was 
not identified in the monitoring wells.

The depth to groundwater measurements in the monitoring wells across the site ranged from 2.26 
feet below the top of casing (ft‐BTOC) in monitoring well MW‐4 to 2.93 ft‐BTOC in monitoring 
well MW‐1. The depth to water in the monitoring wells was within the screened interval.  Based 
on groundwater elevation measurements on March 8, 2023, the direction of groundwater flow is 
generally towards the west. Groundwater flow as determined based on these measurements is 
shown on Figure 4.  Groundwater elevation measurements for this event are presented in Table 
B‐7.   Field notes are included in Appendix A. 
Following gauging, the monitoring wells were purged and sampled with separate, disposable 
polyethylene (PE) bailers for each well. Samples from the wells were decanted into pre‐preserved 
laboratory provided sample containers.  Samples collected from wells were submitted to Waypoint 
Analytical, Inc. under proper chain of custody procedures for testing by Standard Method (SM) 
6200B. 

Laboratory Results 
Analytical results for groundwater samples obtained from site monitoring wells on March 8, 2023 
indicated that one or more VOCs were reported at concentrations exceeding the 2L Standards in 
samples from monitoring wells MW‐1 through MW‐4.  
Laboratory analytical results revealed the following: 
 None of the compounds exceeded the GCLs. 
 Monitoring wells MW‐1 through MW‐3 contained several compounds in excess of the 2L 
Standards. 
 The only compound identified above the 2L Standard in MW‐4 was p‐isopropyltoluene. 
 Removal of the source area in the vicinity of MW‐1 during the tank removal reduced 
concentrations significantly. 

Current and historical groundwater analytical results are summarized in Table B‐4. Current 
groundwater analytical results are shown on Figure 5.  An isoconcentration map showing an 
estimate of benzene concentrations in groundwater is included as Figure 6. 
Copies of the laboratory analytical report and chain‐of‐custody are included in Appendix B.  WR’s 
generalized standard operating procedures are provided in Appendix C.  

SECTION E. CONCLUSIONS AND RECOMMENDATIONS 

This report documents the results of field activities conducted at the site for TA‐01, which included 
the gauging, purging, and sampling monitoring wells MW‐1 through MW‐4. 

Conclusions based on observations, analytical data and research relating to the release at the site 
combined with historical information include the following: 

 The property store is vacant and dilapidated but the residence on the site parcel was 
occupied during site reconnaissance and had a “For Sale” sign in front.  
 The UST system has been removed.

 Municipal water is available along US Highway 301. Currently water is not available along 
Chicken Road, but to date, there are no water supply wells within 1,500 feet along this 
road. 
 Two water supply wells (WSW‐1 and WSW‐2) were identified within a 1,500 ft radius of 
the site, neither of which are active.    
 No wellhead protection areas are located within 1,500 ft of the site.   
 Monitoring wells MW‐1 through MW‐4 were located, gauged, purged, and sampled. 
 LNAPL was not identified at the site. 
 None of the concentrations in the samples collected from MW‐1 through MW‐4 exceeded 
the GCLs. 
 Monitoring wells MW‐1 through MW‐3 contained several compounds in excess of the 2L 
Standards. 
 The only compound identified above the 2L Standard in MW‐4 was p‐isopropyltoluene. 
 The groundwater elevation data indicated a westerly groundwater flow direction. 
 The on‐site inactive water supply well is an approximately 48‐inch diameter dug well that 
was approximately 7.5 feet deep. Approximately two feet of water was present in the 
bottom of the well during the March 8, 2023 sampling event. 
 Removal of the source area in the vicinity of MW‐1 during the tank removal reduced 
concentrations significantly. 

Based on the results of assessment and monitoring activities conducted at the site in association 
with this TA, WR recommends the following: 
 Abandon the inactive on‐site water supply well, WSW‐1. 
 Placement of a NRP with groundwater restrictions on the site property. 
 Consider site closure for this incident.

Dear Liz Allyn:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 3/10/2023 for the analyses presented in the following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method.
The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of
sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-
received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information.
Sincerely,
Angela D Overcash Senior Project Manager

GENERAL STANDARD OPERATING PROCEDURES 

Generalized Standard Operating Procedures (Not All Inclusive)

WithersRavenel
Our People. Your Success.
Soil Sampling, Soil Boring and Monitor Well Installation, Well Development Soil borings are installed utilizing a stainless-steel hand auger, direct-push hydraulic drill or auger rotary
drill using either a macro core™ sampler, hollow stem augers, or air rotary roller cone bit. Soil borings are
typically sampled at discrete intervals from the bucket of a clean stainless steel hand auger, direct push stainless steel sampler with acetate sleeve, or a split barrel sampler. When appropriate, soil samples may be collected from drill cuttings associated with the boring or well installation. Monitor wells are constructed within select soil borings of one, two, or four-inch inside diameter PVC
casing and machine slotted screen in accordance with NCAC Title 15A, Subchapter 02C (Well Construction Standards, Criteria and Standards Applicable to Water Supply and Certain Other Wells). Clean-washed “#2 Torpedo Sand” is typically utilized to fill the boring annulus surrounding the well screen, extending to a minimum of 1-foot above the well screen. A minimum 1-foot thick bentonite clay seal is emplaced above the sand pack and hydrated. Neat cement grout is placed in the remaining annulus
space from the upper portion of the bentonite seal to within 1-foot of surface grade. In coastal plain areas where shallow groundwater is encountered, a variance to construction standards may be employed to ensure the upper portion of the well screen intersects the upper aquifer surface. Wellheads may be completed with either concrete-set flush mounted traffic-bearing steel skirted manholes with bolt down covers or steel above-ground “stick-up” well protectors set in a concrete pad. The monitoring wells are
secured with locking caps. Temporary wells or piezometers may be completed with the PVC riser cut at or above grade, and are abandoned within 24-hours of their installation. Wells may be developed using a bailer, electric submersible pump, pneumatic pump, or peristaltic pump, dependent upon site conditions. When wells are developed by the driller, they may be developed with
any of the methods outlined above, in addition to air or water injection. Soil boring logs and well construction details are typically prepared for presentation in a report appendix. Borings completed in bedrock may be drilled using air rotary, coring, or sonic drilling methods. Groundwater Depth to Water Measurements

Groundwater level measurements are typically obtained using an electronic water level indicator which registers a tone and/or illuminated light when the probe contacts groundwater. Depth to groundwater measurements are obtained by lowering the probe attached to a cable usually marked in 0.01 foot intervals into the well until the probe of the meter intersects the water surface. The measurement from
the top of the riser pipe or top of casing (TOC) to the water level is recorded to the nearest 0.01 foot. The
electronic water level indicator probe and exposed probe cable is decontaminated between measurement locations.

Free Product Level Measurements Light Non-Aqueous Phase Liquid (LNAPL) or “free product” present on the water table is measured using
an electronic oil/water interface probe. The interface probe has both an audible and illuminating light
that indicate when a liquid level is encountered. The oil/water interface probe registers a solid tone and solidly lit light when LNAPL petroleum product is encountered and a beeping tone flashing light when groundwater is encountered. Depth to LNAPL measurements are obtained by lowering the probe attached to a cable marked in 0.01 foot intervals into the well until the probe of the meter intersects the product or groundwater. The measurements from the top of the riser pipe or TOC to the liquid level are
recorded to the nearest 0.01 foot. The thickness of LNAPL is calculated by subtracting the depth to LNAPL measurement from the depth to groundwater measurement. The electronic interface probe is decontaminated between measurement locations. Soil Sampling and Field Screening
Soil sampling is performed in general accordance with ASTM: 1586-84 where applicable. Sampling procedures are followed to protect the chemical integrity of the soil samples and minimize the potential for cross contamination between sample locations, including discarding of the exterior of the sample which contacts the auger bucket, acetate sleeve, or split barrel sampler, the use of stainless steel sampling
equipment, and the thorough decontamination of sampling apparatus prior to use and between sample locations. Soil samples retained as a part of excavation or other intrusive “digging” activities may be collected from the bucket of excavation equipment or using a hand shovel, if appropriate. Care to collect soil samples
from excavation equipment includes retrieving native soil from material that has not made contact with the excavating equipment. Samples are collected in sealable bags or by directly filling sample containers as described above. Sampling is performed using new, disposable nitrile gloves for each sample location to ensure sample
integrity and minimize the potential for cross contamination or field personnel exposure to contaminants.
Sampling equipment such as hand auger extensions and buckets, direct push samplers, split spoons or shovels, are decontaminated prior to their use in the collection of samples. Samples are placed within laboratory grade sample containers provided by the laboratory to which the
samples are submitted, labeled, sealed, and placed in an ice filled cooler. An aliquot of the sample is
typically placed in a clean sealable bag and allowed to reach ambient air temperature for future screening of volatile vapor content with a photoionization detector (PID), flame-ionization detector (FID) or other portable screening device.
Screening of samples with a PID, FID or other field screening device is performed in accordance with
device manufacturer specifications for screening, following calibration of the instrument based on manufacturer recommended procedures.

Generalized Standard Operating Procedures (Not All Inclusive)

Groundwater Sampling Groundwater samples are generally collected using one of three standard methods – through the use of a
dedicated, disposable bailer, a peristaltic pump or submersible electric pump.
When sampling with a bailer, a minimum of three well volumes of groundwater are extracted from the well as a means of purging, unless the well is purged to a “dry” state prior to the removal of three volumes of water. Prior to collection of the groundwater sample with the bailer, the water level is allowed to recover to within 80% of the original level measured prior to purging.
When sampling with a peristaltic or submersible electric pump, polyethylene (PE) tubing (or equivalent) is emplaced into the screened section of the monitoring well, and the pump is used to extract water through the tubing. When using the either of these methods, general water quality measurements including but not limited to pH, temperature, dissolved oxygen (DO), oxygen reductive potential (ORP), specific
conductivity and turbidity may be used as methods for determining when an adequate purge of the well has been conducted. When water quality parameters are measured, the resulting data are included in well purge forms or field notes specific to each site and sampling point. Following the purging of three well volumes of groundwater (in the case of the bailed well) or stability of
monitored measurements (in the case of the peristaltic or submersible electric pump), the groundwater sample(s) are introduced directly into sample containers provided by the laboratory to which samples are ultimately submitted for analysis. Any samples requiring chemical preservation are contained in pre-preserved container(s) provided by the laboratory.
Sampling is performed using new, disposable nitrile gloves for each sample location to ensure sample integrity and minimize the potential for cross contamination of samples or field personnel exposure to contaminants. Water Supply Well Sampling

Sampling of water supply wells is accomplished through the collection of a representative sample from an in-line water tap or other point accessible for sampling. Where possible, the sample is collected from a point prior to any filtration or point of entry (POE) system which might be installed on a well. In some cases, samples will be collected from both pre and post-POE locations. Prior to the collection of samples
through an in-place sampling point, the tap or sampling port is cleaned with an Alconox® and deionized
water solution, rinsed with deionized water, and again with an isopropyl alcohol (IPA) rinse. In the case of active supply wells (e.g., a well with a useable well pump with an active power supply), the well pump is energized and allowed to run for a minimum of ten (10) minutes time, after which a sample is
contained in laboratory grade sample containers as described in the previous section. Water quality
parameters may be (but are not necessarily) measured in association with the well purging. Supply wells without active power supplies are not generally sampled, as the well seal cannot be compromised by individuals not certified as a well contractor. However, in the case of a well with no
power supply or pump installed, samples could be obtained through the use of a bailer, peristaltic pump or
electric submersible pump.

Decontamination Procedures Decontamination procedures employed in the performance of field activities will vary dependent upon
the method(s) of sampling performed at any site, but will generally include the following:
• Remove excess soil/sludge from any sampling equipment as needed, • Wash and scrub the equipment with a phosphate-free detergent such as Alconox® or Liquinox® in a contaminant-free tap water solution. Use a brush to remove particulate matter and surface films as necessary,
• Rinse thoroughly with tap water, • Rinse thoroughly with analyte-free water (deionized water),
 Rinse thoroughly with isopropyl alcohol, • Allow the equipment to air dry,
• Prevent inadvertent contamination during storage and transport (accomplished through storage of equipment in foil or plastic bags/sheeting). In the case of disposable bailers and tubing utilized for the purging and sampling of wells, these items may be decontaminated prior to their disposal. In general, no decontamination of these items is necessary
prior to their use in sampling.
