1. INTRODUCTION
Geosyntec consultants of NC, P.C. (Geosyntec) is pleased to submit this Brownfields Assessment
Report (Report) on behalf of the Prospective Developer (PD), 2830 Highway 421 Owner, LLC (the
current property owner) for the property located at 2830 US Highway 421 N, Wilmington, North
Carolina (herein referred to as the “Site”). The Site is comprised of 80.31 acres and is identified
as New Hanover County Parcel ID R04000-003-013-000. The Site location is shown on Figure 1
and the Site layout is shown on Figure 2. The PD submitted a Brownfields Application (BPA) to
the North Carolina Department of Environmental Quality (NCDEQ) Division of Waste
Management (DMW) Brownfields Program (NCBP) on 5 April 2022. The Brownfields
Application was issued a Letter of Eligibility (LOE) on 21 April 2022.
The Site was historically used as a fertilizer plant from 1963 until 1997. Since 2005, the Site has
operated as a scrap metal processing facility that included metal recycling, warehousing, and an
automotive shop. The current operations at the Site include a commercial retail warehouse and
storage of construction related equipment. The proposed redevelopment on the Site includes an
approximately 2,000 linear foot (LF) utility corridor and an approximately 12,000 square foot (SF)
prefabricated commercial warehouse building (Figure 2). The proposed redevelopment activities
are not anticipated to disturb the existing concrete slab, except for the potential installation of
footers to structurally support the prefabricated warehouse. If the addition of building footers is
required, it is only expected to result in localized areas of slab removal for the purposes of new
foundation construction. Additional redevelopment plans for the Site are not yet finalized but may
include demolition of the remaining existing buildings and construction of new commercial
buildings. Residential development was considered as an option within the BPA; however,
residential development plans are not being considered at this time.
A teleconference with Geosyntec (Ms. Kaitlyn Rhonehouse and Dr. Frank Stillo) and NCBP (Ms.
Sharon Eckert and former NCDEP employee Ms. Kathleen Markey) was held on 2 August 2022
to discuss Site redevelopment plans and additional sampling required to obtain a Brownfields
Agreement (BFA). A Work Plan for Brownfields Assessment (Work Plan) ) was submitted on 12
August 2022 to outline the site assessment scope of work as discussed with NCDEQ. A subsequent
meeting with Geosyntec and NCBP (Ms. Sharon Eckert and Ms. Claire Sorrell) was held on 9
September 2022 to discuss the Work Plan. NCBP conditionally approved the Work Plan with
comments in a 9 September 2022 email and requested the plan be resubmitted to address NCDEQ’s
comments. This Report documents the results of the sampling conducted as presented in the final
approved Work Plan (dated 13 September 2022). In addition, this Report presents the results of
supplemental soil sampling for arsenic. Elevated arsenic was detected in one area of the Site during
initial sampling and, therefore, a second round of targeted arsenic sampling was conducted to
delineate the impacts. A proposed plan to complete voluntary soil removal of arsenic-impacted
soil is outlined herein to limit risk to construction workers.

CAR220197/GN9094 2 November 2022

Assessment activities were conducted in general accordance with the Work Plan for Brownfields
Assessment –REV01 dated 13 September 2022. The Work Plan was prepared in general accordance
with NCDEQ DMW NCBP Minimum Requirements Checklist for Site Assessment Work Plans and
Reports (February 2022). Assessment activities were conducted in general accordance with
applicable guidance including, United States Environmental Protection Agency (EPA) Region 4,
Laboratory Services and Applied Science Division, Soil Sampling Operating Procedure (June
2020), and the NCDEQ DWM Vapor Intrusion Guidance (March 2018). NCDEQ’s risk-based
evaluation process and Risk Calculator Tool (July 2022) was also used to evaluate the data.
1.1 Site Environmental History
Until at least 1958, the Site appears to have been undeveloped vegetated land. Beginning in 1963,
the Site operated as a nitrogen fertilizer plant until its closure in 1997. The Site is believed to have
been originally developed and operated by Carolina Nitrogen Corporation. The ownership entity
reportedly went through several mergers before the Site was operated by PC Nitrogen beginning
in 1963. The Site was subsequently acquired by multiple parties from 1963 until closure in 1997
operating as a nitrogen fertilizer plant. Between 2005 and approximately 2021 the Site operated
as a scrap metal processing facility including scrap metal recycling, warehousing, and an
automotive shop and is currently owned by 2830 Highway 421 Owner, LLC. Scrap metal
operations ceased by 2021. The Site is currently used for warehousing and construction equipment
storage.
A Phase I Environmental Site Assessment (ESA) prepared by Geosyntec, dated 3 May 2022,
identified recognized environmental conditions (RECs1) associated with the Site. Historical
assessment reports prepared by others, which were provided to Geosyntec by the PD, indicate the
Site soil and groundwater is impacted with environmental contamination. The Site-related
environmental impacts are understood to stem from previous on-site activities that are no longer
ongoing and are unrelated to 2830 Highway 421 Owner, LLC.
In July and August 2021, Geosyntec performed a Limited Phase II ESA (Phase II ESA) to evaluate
Site conditions. Soil, groundwater, and surface water samples were collected during Phase II ESA
activities. Soil sample analytical results revealed one semi-volatile organic compound (SVOC)
(i.e., Benzo(a) pyrene) and two metals (i.e., arsenic and hexavalent chromium) above Residential
Preliminary Soil Remediation Goals (PSRGs) in one or more samples; hexavalent chromium was
detected above its Commercial/Industrial PSRG in one sample. Polychlorinated biphenyls (PCBs)
(i.e., total PCBs and PCB congener 126) were detected above the Protection of Groundwater
(POG) PSRG in the vicinity of a historical release of approximately three gallons of PCB-
containing transformer oil from the electrical substation (Geosyntec, 2022). No volatile organic

1 As the term REC is defined by the ASTM E1527-13 Standard.

CAR220197/GN9094 3 November 2022

compounds (VOCs), SVOCs, or metals were detected above Title 15A NCAC 2L Groundwater
Standards (2L Standards). Nitrate-nitrite was reported above its 2L Standard in one sample. No
targeted analytes were detected above their corresponding standards in the surface water samples.
1.2 Brownfields Assessment Objectives
The objective of the Assessment was to further evaluate environmental Site conditions for the
purpose of facilitating safe Site reuse and redevelopment. Assessment activities focused on data
collection to evaluate the following:
 Evaluate potential vapor intrusion risks for future and existing on-site structures through
the collection of soil gas samples. Soil gas samples were collected in the vicinity of the
proposed approximately 12,000 SF building footprint, and beneath the former automotive
repair shop, the former maintenance warehouse, and current retail warehouse.
 Evaluate potential soil direct contact risks to construction workers in the proposed utility
corridor.
 Evaluate soil conditions near existing utility infrastructure to support redevelopment
planning and potential connection to future utility infrastructure. Specifically, this data was
collected to aid in the development of a focused Environmental Management Plan (EMP).
The remainder of this Report outlines the results of soil and soil gas sampling performed as
outlined in the Work Plan. Section 4 also presents Geosyntec’s intent to conduct to a limited soil
removal of arsenic-impacted soil to reduce overall site risk and conduct limited groundwater
sampling.

CAR220197/GN9094 4 November 2022

2. SCOPE OF WORK AND SAMPLING METHODOLGY
2.1. Health and Safety and Site Access
Before the start of the scope of work described herein, Geosyntec prepared a Site-specific Health
and Safety Task Hazard Analysis (THA) in general accordance with the Occupational Safety and
Health Administration (OSHA) rules (29 CFR 1910.120). To address potential underground
utilities, Geosyntec contacted the North Carolina 811 one-call system a minimum of 72 business
hours before beginning subsurface work to notify member utilities of the subsurface work. Because
811 utility locating services only identify utilities up to the property boundary, Geosyntec
coordinated with ESP Associates, Inc., a private subsurface utility exploration (SUE) surveyor, to
identify subsurface utilities in the work areas and supplement the work performed by NC 811.
2.2. Soil Gas Sampling
On 21 September 2022, Geosyntec mobilized to the Site and observed Catlin Engineers and
Scientists (Catlin) of Wilmington, North Carolina, a North Carolina-licensed driller, to install one
exterior soil gas probe (SGP) and 13 sub-slab soil gas probes (SSPs) (Table 1; Figure 3). Twelve
of the thirteen SSPs were able to be installed; SSP-13 was unable to be installed, which is discussed
in greater detail in the forthcoming section 2.2.2. Soil gas and sub-slab probes were installed in
general accordance with the Work Plan and the NCDEQ Division of Waste Management, Vapor
Intrusion Guidance Version 2, March 2018 and Vapor Intrusion Assessment Work Plan & Report
Checklist, February 2022 and as summarized in the following sections.
2.2.1. Deep Soil Gas Probe (SGP-01)
The soil boring for SGP-01 was advanced to approximately 5 feet (ft) below ground surface (bgs)
to evaluate soil gas north of the former maintenance building and former automotive repair shop
along the proposed utility corridor (Table 1). The borehole was advanced using direct push
technology (DPT). The SGP was constructed with a ¼-inch diameter Nylaflow® tubing connected
with a shark-tooth fitting to a ¼-inch-diameter stainless steel sampling probe. The probe was
installed inside the borehole and a sand filter pack was placed in the annulus to a height of
approximately six inches above the top of the soil gas implant. Granular bentonite was then placed
in the remaining annulus in six-inch lifts to the ground surface. The bentonite was hydrated after
each lift. The top of the probe was fitted with a compression-fit brass ball valve to maintain an air-
tight seal between installation and sampling. The soil vapor probe was then allowed to equilibrate
for approximately 48-hours prior to sampling.
2.2.2. Sub-Slab Soil Gas Probes (SSP-01 through SSP-12)
To evaluate sub-slab conditions for proposed and future redevelopment, SSPs were installed in the
following locations: within the footprint and adjacent to the proposed 12,000 SF building footprint
(SSP-03 through SSP-06 and SSP-12 and SSP-13); beneath the former maintenance building (SSP-

CAR220197/GN9094 5 November 2022

01 and SSP-02); beneath the former automotive repair shop (SSP-07 through SSP-09); and beneath
the current retail warehouse (SSP-10 and SSP-11) (Table 1 and Figure 3).
Sub-slab soil gas sampling was conducted using a Vapor PinTM (Vapor Pin). To install the Vapor
Pin, a North Carolina-licensed driller used a hammer drill with a 5/8-inch drill bit to drill a hole
through the concrete slab at the sample locations. The sub-slab thickness varied across the Site
from approximately 8-inches up to 18-inches. Geosyntec was unable to install SSP-13 due to a
potential buried concrete footing with a concrete thickness of greater than 36-inches buried below
approximately 18 inches of soil. Geosyntec attempted to off-set SSP-13 by up to 20 feet without
success due to the same conditions described above. Given the field constraints, SSP-13 was
unable to be installed.
The Vapor Pin was installed in the hole following the procedures supplied by the Vapor Pin
manufacturer. A dead blow hammer was used to tap the Vapor Pin into the drilled hole, barbed
side down. Following installation, a protective cap was placed over the Vapor Pin to prevent vapor
loss prior to sampling. Nylaflow® tubing was used to connect to the Vapor Pin using compression
fittings during sampling. Each vapor pin was allowed to equilibrate overnight.
2.2.3. Soil Gas Sample Screening and Collection
Geosyntec mobilized on 22 and 23 September 2022 to collect soil gas samples from SSP-01
through SSP-12 and SGP-01. Soil gas samples were collected in pre-evacuated, batch certified-
clean 1-L Summa® canisters equipped with 200 milliliters per minute (mL/min) flow controllers.
A “shut-in test” was conducted to assess the assembly for air leaks. Following the completion of a
successful shut-in test, each probe was purged of at least three purge volumes prior to sampling.
Each purge volume was screened for: (i) oxygen, carbon dioxide, and methane with a landfill gas
meter (Landtech GEM 2000); and (ii) organic vapors with a PID. During field screening, a tracer
test was conducted to verify that a significant amount of atmospheric air did not enter the sample
through the annular seal or associated fittings. A helium shroud was used during sampling as a
leak check for outdoor air being introduced into the samples. The shroud was placed around the
ground surface of each probe and soil gas sampling assembly prior to sample collection and a
tracer gas (helium) was added inside the shroud during the purging process. Field screening
measurements (PID, oxygen, carbon dioxide, methane, and helium) were collected from purged
soil gas in the Tedlar sampling bag. The concentration of tracer in the shroud and in the field
screening samples were recorded with a field meter. If the field screening indicated the tracer was
detected above 5% of the minimum concentration in the shroud, fittings were checked and/or the
probe was resealed/replaced as needed to obtain a sample with appropriate integrity. Helium was
not detected in field screen samples during purging.
As soon as practical after purging, soil gas samples were collected using 1-L batch-certified
SUMMA® canisters from the analytical laboratory. After sample collection, the residual vacuum
was also measured and recorded and was no less than -5 inches of mercury (inHg). Soil gas samples

CAR220197/GN9094 6 November 2022

were submitted under standard chain of custody protocol via laboratory courier to Eurofins Air
Toxics, LLC (National Environmental Laboratory Accreditation Conference [NELAC]) for VOCs
analysis by EPA Method TO-15. To assess analytical precision, one blind duplicate sub-slab soil
gas sample (DUP-01 and associated with parent sample SSP-09) was collected from the
automotive repair shop (per NCDEQ request) using two Summa canisters connected in parallel.
Following review of this report, soil gas probes will be abandoned using grout and/ or bentonite.
2.3. Soil Sampling
On 21 September 2022, Geosyntec mobilized to the Site and observed Catlin advance eight soil
borings (SB-01 through SB-08) using DPT to approximately 5 ft bgs (Table 1; Figure 3). Soil
was collected in 1-ft intervals, visually inspected, screened with a photo-ionization detector (PID),
and classified for lithology (Appendix A).
One discrete grab soil sample was collected from each boring at the interval exhibiting the greatest
evidence of impacts (i.e., elevated PID readings or staining) (Table 1). In locations where there
was an absence of evidence of impacts, the sample was collected from directly above the deepest
interval. For each boring, one composite sample was collected by homogenizing the soil from
approximately 0.5 ft bgs to 5 ft bgs in a decontaminated stainless-steel bowl. Homogenized
samples were placed into laboratory-supplied bottle ware.
Discrete grab samples were placed into labeled laboratory supplied bottle ware designated for
VOC analysis by EPA Method 8260. Composite samples were analyzed for SVOCs by EPA
Method 8270, Resource Conservation and Recovery Act (RCRA) metals by EPA Method 6010,
mercury by EPA Method 7471, and hexavalent chromium by EPA Method 7199. Bottle ware was
labeled with the sample location, date, and time, placed on ice, and submitted to Eurofins in
Savannah, Georgia, a North Carolina certified (NC WW/GW LC) labaroatory (No. 269, expiration
date 31 December 2022), via laboratory courier for analysis following chain-of-custody
procedures.
On 27 October 2022, Geosyntec mobilized to the Site to confirm September 2022 sample SB-04
arsenic results (discussed in Section 3) and assess the extent of arsenic-impacted soil. Geosyntec
offset the October 2022 SB-04 resampling location by 1 ft from previous sampling. Geosyntec
advanced three soil borings perpendicular to the proposed utility corridor (SB-04DW6, SB-04DE6,
and SB-04DE122) using a hand auger to approximately 2 ft bgs and three soil borings within the
proposed utility corridor (SB-04, SB04DN6, and SB-04DS6) using a hand auger to approximately
5 ft bgs (Table 1; Figure 4). For each boring, one composite sample was collected by

2 The naming convention for the soil samples includes the direction from the original sample SB-04 (e.g., W for west,
E for east), the distance in feet from the original sample (e.g., 6 for 6 feet), and the sample depth interval (e.g., 0-2’
for composite samples between 0 and 2 feet below ground surface).

CAR220197/GN9094 7 November 2022

homogenizing the soil from approximately 0.5 ft bgs to 2 ft bgs in a decontaminated stainless-steel
bowl. For soil borings within the proposed utility corridor, one additional composite sample was
collected by homogenizing the soil from approximately 2.5 ft bgs to 5 ft bgs to evaluate depths
where soil could be disturbed during utility installation. Homogenized samples were placed into
laboratory-supplied bottle ware. Composite samples were analyzed for arsenic by EPA Method
6020. Bottle ware was labeled with the sample location, date, and time, and submitted to Eurofins
in Savannah, Georgia, a North Carolina certified (NC WW/GW LC) laboratory (No. 269,
expiration date 31 December 2022), via laboratory courier for analysis following chain-of-custody
procedures.
2.4. Soil Boring and Soil Gas Sample Locating
A handheld GPS unit and field measurements was used to collect the approximate coordinates of
the soil borings and soil gas sample locations. Final soil gas and soil boring locations are depicted
on Figure 3.
2.5. Soil Boring Abandonment
Following sample collection, soil borings were abandoned by placing composited fill back into the
open boreholes and/or grouting or filling with bentonite to land surface. Soil gas sample locations
will be abandoned by grouting or filling with bentonite to surface following review of this report.
2.6. Decontamination
Disposable equipment was used as practical during field assessment activities. Equipment used
between sample locations was decontaminated using an initial water rinse followed by cleaning
with Alconox® and a final rinse of distilled water in general accordance with EPA Region 4,
Laboratory Services and Applied Science Division, Field Equipment Cleaning and
Decontamination Operating Procedures (June 2020).
2.7. Investigation Derived Waste (IDW)
No field evidence was observed during assessment activities that suggested the collect soil cuttings
were impacted. As a result, IDW generated from soil borings was backfilled into borings.
Decontamination liquids were decanted into each boring. Soil analytical results (discussed in
Section 3) found one sample above 20-times the regulatory limit for toxicity characteristic for
arsenic. Therefore, a Toxicity Characteristic Leaching Procedure (TCLP) analysis for arsenic was
performed on sample SB-04 2-5’. Arsenic was detected below the characteristic regulatory limit
(5 mg/L) at a concentration of 3.48 mg/L (Appendix C). Soil analytical results are consistent with
the field observations and the IDW management method used during field assessment activities.

CAR220197/GN9094 8 November 2022

2.8. Receptor Survey
On 7 July 2022, Geosyntec conducted a receptor survey to support redevelopment of the Site. The
receptor survey is presented in Appendix B. The New Hanover County GIS online database was
used for parcel identification and layout. Potential water supply well information was obtained by
performing a windshield survey. Geosyntec also reviewed the NCDEQ wellhead protection areas
(WHPAs) using the online NCSWAPInfo (SWAP) site and obtained an Environmental Risk
Information Services (ERIS) Physical Setting Report (PSR) dated 18 June 2021 for the area within
1,500 ft radius of the Site to support the receptor survey. The SWAP identified “Well #1” located
within 100 ft upgradient to the west of the Site. The windshield survey identified 9 potential wells
within 1,500 ft of the Site in a residential zoned area southwest of the Site.
The parcels within a 1,500-ft radius are summarized in Appendix B.
3. INVESTIGATION RESULTS
Soil gas and soil analytical results for constituents detected above the laboratory reporting limits
(RLs) in one or more samples are presented in Table 2 and Table 3, respectively. Supplemental
soil analytical results for arsenic constituents are presented in Table 4. Constituents detected in
soil gas above a Vapor Intrusion Screening Level (VISL) are shown on Figure 5. Constituents
detected in soil above an NCDEQ direct exposure Preliminary Soil Remediation Goal (PSRG) are
shown on Figure 6. Supplemental soil analytical results for arsenic constituents are shown on
Figure 7. Laboratory analytical reports are included in Appendix C.
3.1. Soil Gas Analytical Results
Twelve soil gas samples and one laboratory blind duplicate soil gas sample were collected on 22
and 23 September 2022. The primary findings associated with the soil gas analytical results are as
follows:
 Trichloroethene (TCE) was detected above its Non-Residential VISL (180 micrograms
per cubic meter [µg/m3]) at SSP-02 at a concentration of 200 µg/m3. TCE was detected
above the Residential VISL (14 µg/m3) but below the Non-Residential VISL (180 µg/m3)
in SSP-01 at a concentration of 39 µg/m3. Both samples were collected from within the
former automotive repair shop.
 Tetrachloroethene (PCE) was detected above its Residential VISL (278 µg/m3) but below
the Non-Residential VISL (3,500 µg/m3) in SSP-07 at a concentration of 1,300 µg/m3.
 1,4-Dioxane was detected above its Residential VISL (19 µg/m3) but below the Non-
Residential VISL (250 µg/m3) SSP-04 at a concentration of 25 µg/m3.

CAR220197/GN9094 9 November 2022

 Chloroform was detected above its Residential VISL (4.1 µg/m3) but below the Non-
Residential VISL (53 µg/m3) in SSP-08 at a concentration of 22 µg/m3.
No other VOCs were detected in soil gas samples above the residential or non-residential VISLs.
3.2. Soil Analytical Results
Eight soil samples and one duplicate soil sample were collected on 21 September 2022. The
primary findings associated with the soil analytical results are as follows:
 VOCs: No VOCs were detected at a concentration above the Residential or
Industrial/Commercial PSRGs.
 SVOCs: No SVOCs were detected at concentrations above the Residential or
Industrial/Commercial PSRGs.
 Metals: Arsenic was detected above the Non-Residential PSRG (3.0 milligram per
kilogram [mg/kg]) at SB-04 at a concentration of 35.1 mg/kg. No other metals were
detected above a direct exposure PSRGs
 Nine soil samples and one duplicate soil sample were collected on 27 October 2022 and
also tested for arsenic. Arsenic was detected above the Non-Residential PSRG at four soil
borings at concentrations ranging from 6.05 mg/kg to 729 mg/kg.
Based upon detections of arsenic in soil at SB-04, Geosyntec is proposing a limited soil removed;
details are discussed further in Section 4.
3.3. Risk Evaluation
Based upon detections of constituents in soil gas above VISLs and the detections of constituents
in soil above PSRGs, Geosyntec conducted risk-based screening evaluations in accordance with
the Revised Technical Guidance for Risk-Based Environmental Remediation of Sites (Risk-Based
Guidance) (NCDEQ, 2020).
The analytical results input into the NCDEQ Risk Calculator included the maximum concentration
of each detected compound, including estimated values, and the RL for compounds that were not
detected in the samples but where the RL exceeded the residential VISL (NCDEQ, 2022).
Cumulative cancer risk below 1E-4 and cumulative non-cancer hazards less than 1.0 are
considered acceptable, as indicated in the Risk-Based Guidance (NCDEQ, 2020). Risk calculator
summaries and outputs are included in Appendix D. The findings associated with potential vapor
intrusion risks and direct contact to soil risk calculators are summarized in the following
subsections.

CAR220197/GN9094 10 November 2022

3.3.1. Soil Gas Risk Screening Results
The current redevelopment plans for the Site are commercial/industrial; however, as discussed in
Section 1 and with NCDEQ, the BPA considers the potential of residential redevelopment.
Therefore, the hypothetical soil gas to indoor air pathway was considered for both residential and
commercia/industrial occupants (i.e., non-residential). Based upon the results of the risk calculator,
the non-residential soil gas to indoor air carcinogenic risk was estimated to be 8.6E-06 and the
non-cancer hazard index is estimated to be 0.52, each of which indicates no unacceptable vapor
intrusion risk for the non-residential worker scenario. Despite the exceedance of conservative non-
residential VISL for TCE at one location (SSP-02), the cumulative cancer and non-cancer risks are
within acceptable levels.
The calculated resident carcinogenic risk is estimated to be 1.2E-04 and the non-carcinogenic
hazard index is estimated to be 6.5, which are both considered an unacceptable risk to the
residential receptor. The non-cancer hazard index in this instance is being primarily driven by the
detections of TCE, which is a detected constituent that is elevating non-carcinogenic risk to an
unacceptable value. TCE has a calculated non-carcinogenic hazard index of 2.9.
3.3.2. Soil Risk Screening Results
The potential exposure risks to direct contact with soil included screening hypothetical non-
residential workers and construction workers. The non-residential workers were considered based
upon the intended commercial/industrial redevelopment. The construction worker receptors were
considered to guide decision making as it relates to the overall planned redevelopment, and
specifically to the utility corridor installation that has been contemplated to date. The soil risk
screening information is also intended to inform the development of the soil management strategies
to be included within the pending EMP.
Prior to the October 2022 arsenic sampling, non-residential worker calculated carcinogenic risk
and the non-carcinogenic hazard index were estimated to be 0.21 and 1.5E-05, respectively, each
of which within the acceptable risk levels for the non-residential worker. The construction worker
carcinogenic risk and calculated non-carcinogenic hazard index were estimated to be 3.2E-06 and
1.0, respectively, which are also within or equal acceptable levels. Although the Site is not
currently planned for residential use, the residential carcinogenic risk and non-carcinogenic hazard
index were calculated. The carcinogenic risk is estimated to be 3.2, which is considered
unacceptable risk. The Site is not intended to be used for residential use at this time and will be
reevaluated upon future residential develop planning. We note that each of the RC runs for soil
follow the default guidance which uses RLs and there were numerous elevated RLs that affected
the calculated risks. However, we also note that one elevated detection of arsenic was also partially
driving risk, particularly for construction workers; therefore, the October 2022 arsenic sampling
discussed in Section 2 was conducted.

CAR220197/GN9094 11 November 2022

The primary non-cancer hazard driver for both non-residential and construction worker receptors
is arsenic, which was detected in the SB-04 composite at concentration of 35.1 mg/kg. The PD
intends to remove soil in the vicinity of SB-04 (Figure 7). Therefore, a separate RC run was
completed which removed the detections from September and October sampling at SB-04 and
replaced the arsenic concentration with the next highest arsenic detection that will remain on-site
(7.6 mg/kg at SB-04 DN6). By removing this soil, the non-residential worker calculated
carcinogenic risk and the non-carcinogenic hazard index is estimated to be 6.0E-06 and 0.14,
respectively, each of which are well within the acceptable risk levels for the non-residential
worker. The construction worker carcinogenic risk and calculated non-carcinogenic hazard index
is estimated to be 1.1E-06 and 0.38, respectively, which are also within acceptable levels.
4. FINDINGS AND CONCLUSIONS
The objective of this Assessment was to evaluate environmental Site conditions for the purpose of
facilitating safe Site redevelopment. The objective was met through the collection of:
 soil gas samples to evaluate potential vapor intrusion risks for future non-residential
receptors in on-site buildings
 soil samples to evaluate potential direct contact soil exposure risks to construction workers
during redevelopment
 soil samples to evaluate soil management options as it relates to developing an EMP
specifically focused on a planned utility corridor installation
4.1. Soil Gas Management
Current development plans contemplate commercial Site reuse in the form of warehousing. One
exterior soil gas probe and 12 sub-slab soil gas samples were collected for VOC analysis across
the Site. The results indicate localized areas of elevated concentrations of some chlorinated VOCs,
particularly one detection of TCE above the Non-Residential VISL in the sub-slab sample beneath
the former automotive repair shop (SSP-02). The former automotive repair shop was previously
demolished and has no associated structure present on-site. Additionally, PCE was detected in
eleven of the twelve sub-slab samples collected, but below the Non-Residential VISL for each
case. PCE was not detected in the soil gas probe sample collected at 5 ft bgs and not detected in
previous groundwater sampling events at the Site (Geosyntec, 2022). The source of the chlorinated
VOCs found in soil gas is unknown and is suspected to be limited in nature, localized toward the
western portion of the Site. Although the source of the PCE and TCE in soil gas is currently
unknown, the soil gas data was valuable in evaluating potential vapor intrusion exposure risks for
on-site existing and/or future structures.
No unacceptable vapor intrusion risks were identified for non-residential receptors based upon the
results of the NCDEQ Risk Calculator. Further, the risk screening results presented herein remain
conservative, particularly because the results do not consider spatial variability in soil gas
concentrations. In other words, the one non-residential VISL exceedance (TCE at SSP-02) was
identified on the western portion of the Site; however, several soil gas samples surrounding SSP-

CAR220197/GN9094 12 November 2022

02 indicate TCE concentrations in soil gas below screening levels. The Risk Calculator
conservatively assumes the maximum detected concentration of each chemical, including TCE, is
equally distributed spatially across the Site, which is not the case. Despite the conservativism, the
cumulative cancer and non-cancer risks are calculated to be within acceptable levels for the non-
residential receptor. As a result of this evaluation, the data collected herein indicate vapor intrusion
mitigation measures are not warranted for the planned non-residential Site reuse. The non-cancer
hazard index for the residential Site receptor indicated an unacceptable risk to a hypothetical
residential receptor. If different end uses are contemplated, such as residential redevelopment, an
updated vapor intrusion risk screening may be appropriate to evaluate potential vapor intrusion
related considerations.
4.2. Soil Management
Eight soil samples were collected for laboratory analysis in the proposed utility corridor and three
soil samples were collected in proximity to existing infrastructure (northwest corner of the Site) to
guide soil management decisions as it relates to future earthwork during redevelopment. An
additional nine supplemental soil samples for arsenic were collected to confirm previous soil
sampling at SB-04 and to evaluate the potential impacted area for arsenic. Arsenic was detected
above the industrial/commercial PSRG in one location along the eastern property boundary (SB-
04). No other chemicals analyzed were detected above the applicable soil screening levels. A Site-
wide risk evaluation was conducted, and the results indicate no unacceptable risk to the
hypothetical construction worker or non-residential workers. It should be clarified that the
cumulative non-cancer hazards to construction workers is 1.0, which is the highest allowable risk
within the acceptable risk range. However, NCDEQ’s Risk-Based Guidance specifically indicates
that risk-based clean-up levels should not be made based upon the results of a construction worker
exposure scenario because of the assumptions implicit into the construction worker risk screening
calculation. Rather, the results of the construction worker scenario should be used to guide health
and safety planning during construction. Therefore, despite the “near exceedance” of the
construction worker direct contact soil exposure scenario, Geosyntec recommends that exposure
risks to construction workers are managed with proper personal protective equipment (PPE), which
can be detailed in the forthcoming EMP.
Overall, the soil sampling results collected herein are effective at developing an understanding of
the shallow soil conditions along the planned utility corridor and will be incorporated into soil
management strategies as part of the forthcoming EMP
4.3. Proposed Supplemental Assessment
4.3.1. Objectives
The scope of work for this investigation was completed to meet the following objectives:
 Obtain groundwater data to evaluate groundwater upgradient of SSP-02
 Remove arsenic impacted soil at SB-04

CAR220197/GN9094 13 November 2022

Although no unacceptable risk was calculated for the receptors considered for Non-Residential
use, TCE was detected above the Non-Residential VISL in the sub-slab sample beneath the former
automotive repair shop (SSP-02). The PD proposes to install an upgradient monitoring well
adjacent to the western property line to the west of SSP-02 to evaluate potential upgradient sources
of TCE, if any.
Although no unacceptable risk was calculated for the receptors considered, arsenic was detected
above the industrial/commercial PSRGs at SB-04 between 2 ft and 5ft. The PD plans to excavate
and export approximately 50 cubic yards (cu. yds.) of arsenic-impacted soil to the New Hanover
County Landfill as non-hazardous waste or a lined Subtitle D landfill based on the results of TCLP
analysis of the proposed exported soil. The approximate area of soil to be exported is shown on
Figure 7 and is 216 square feet to a depth of approximately 6 ft. Waste manifests/haul tickets will
be provided to NCBP. No confirmation samples are proposed (existing October 2022 data will be
used). The excavation area will be backfilled with soil from the Site (no soil will be imported).
4.3.2. Sampling Methodology
Health and Safety Planning and Utility Clearing
Prior to the start of work, Geosyntec will prepare a site-specific Health and Safety Task Hazard
Analysis in general accordance with the Occupation Safety and Health Administration (OSHA)
rules (29 CFR 1910.120). To address potential underground utilities, Geosyntec will contact the
North Carolina 811 one-call system a minimum of 72 business hours before beginning the
assessment to notify member utilities of the subsurface work. In addition, soil sampling locations
will be cleared by a private utility locator. Field procedures will generally follow the Operating
Procedures as determined by the U.S. Environmental Protection Agency (USEPA) Region IV
Science and Ecosystem Support Division (SESD). The most current versions of these operating
procedures can be downloaded at: https://www.epa.gov/quality/quality-system-and-technical-
procedures-sesd-field-branches. Additional media specific procedures are discussed further below.
Monitoring Well Installation and Groundwater Sampling
A temporary monitoring well will be installed by a North Carolina-licensed driller and will be
advanced using DPT drilling techniques. Proposed location shown in Figure 3. The temporary
monitoring well will be installed to approximately 25 ft bgs, and at least 5 feet below the water
table as observed in the field. The water table is expected to be encountered at approximately 17
to 20 ft bgs based on measurements reported from previous assessments at the Site.
The temporary monitoring well will be installed with a 10-ft section of 1-inch diameter 0.010-inch
slotted SCH-40 polyvinyl chloride (PVC) screen, and with 1-inch diameter SCH40 PVC riser pipe
to the surface. A 20/30 silica sand filter pack will be installed to surface.
Low-flow micro-purge sampling techniques via peristaltic pump will be employed for sample
collection if conditions allow. The pump intake or tubing will be placed in the mid-portion of the
screened interval of the well or the mid-portion of the water column. To the extent practical, the

CAR220197/GN9094 14 November 2022

purge rate will be set to minimize drawdown. Once approximately three equipment volumes are
purged and purge water is visibly clear, a sample will be collected directly into laboratory supplied
sample containers. Well purging will not exceed one hour. Sample containers will be stored on ice
and submitted under chain of custody to a North Carolina-certified laboratory for analysis of VOCs
by Method 8260.
Prior to collecting a groundwater sample, water level measurements will be recorded from the
temporary groundwater monitoring well using a water level meter. Static water level and total well
depth will be measured to 0.01 feet. The top-of-casing elevations will not be surveyed.
Decontamination
Disposable equipment was used as practical. Non-disposable equipment was decontaminated
using an initial water rinse followed by cleaning with Alconox® and final rinse of deionized water,
as needed.
Sample Point Locating
A handheld GPS unit was used to collect the approximate coordinates of the temporary monitoring
well.
Investigative Derived Waste
Investigative Derived Waste (IDW) (e.g., excess soil cuttings and development/purge water) will
be placed back into borings or distributed on-site.
4.3.3. Laboratory Analysis
Laboratory Analysis
Following collection, groundwater sample containers will be sealed and submitted to a fixed-based
laboratory with appropriate certification following chain of custody procedures.
Laboratory Certifications
The groundwater analysis laboratory will be a North Carolina-certified laboratory. Laboratory
certifications can be shared upon request.
Laboratory Reporting
Laboratory reporting limits (RLs) and method detection limits (MDLs) used by the selected
laboratory for methods will meet Title 15A NCAC 2L Groundwater Standards (2L Standards) to
the extent feasible. Concentrations detected between the reporting limit (RL) and method detection
limit (MDL) will be reported as estimated values and flagged in the laboratory analytical report
with a “J”. Level II Quality Assurance (QA)/Quality Control (QC) will be reported in the analytical
report deliverable.

CAR220197/GN9094 15 November 2022

4.3.4. Quality Assurance/ Quality Control
Field and Laboratory Procedure QA/QC
One duplicate sample will be collected in the field to assess field sampling methods.
Chain of Custody QA/QC
Geosyntec will initiate chain of custodies for samples in the field, documenting sample collection
information including but not limited to:
• The sample collector’s name
• Project information and location
• Geosyntec Project Manager contact information
• Sample identification number
• Date and time of sample collection
• Type of analysis
• Type of sample container
Samples will remain in the custody of Geosyntec until they are ready for shipment. Geosyntec will
relinquish the samples and chain of custodies (noting date and time of relinquishment) to the
laboratory courier who will sign the chain of custody as receiver (noting date and time again).
Geosyntec will retain a copy of the chain of custodies signed by the courier.
4.3.5. Reporting
Upon receipt of laboratory results, Geosyntec will prepare a written report summarizing: (i) the
scope of work executed, and sampling methodologies performed; (ii) groundwater sample
laboratory analytical results; (iii) recommended IDW management procedures; and (iv) findings,
conclusions and recommendations. Tabulated groundwater sample results compared to associated
2L Standards and figures depicting the final sample locations will be included to the report.
Analytical results will be evaluated using the July 2022 (or most recent) version of the NCDEQ
Risk Calculator as appropriate. The report will include Geosyntec’ Corporate Professional
Engineer (PE)/Professional Geology (PG) License Numbers and will be sealed and signed by the
licensed PE or PG who oversaw the work.

Source Water Assessment Program Report for
D H GRIFFIN
Transient Non-Community Water System
Introduction: What is a Source Water Assessment?
The North Carolina Division of Water Resources, Public Water Supply (PWS) Section is responsible for implementing
the Source Water Assessment Program (SWAP) and completing assessments for all public drinking water supplies in
the state. The 1996 amendments to the Safe Drinking Water Act provided federal support and required states to conduct
assessments of all public water systems. A source water assessment is a qualitative evaluation of the potential of a
drinking water source to become contaminated by the identified potential contaminant sources (PCS) within the
delineated area. In North Carolina there are approximately 8,000 public water supply sources that were assessed by the
state. The PWS Section has gathered information for each water supply and developed a process for completing the
assessments. This process is summarized in the next few pages and detailed in Section 6 of this report.
This report provides a summary of the results for the Source Water Assessment for your drinking water source(s).
What is the Source of Your Drinking Water?
Everyone wants clean, safe drinking water and we assume this natural resource will always be available to us. However,
drinking water sources can be threatened by many potential contaminant sources, including underground storage tanks
for gasoline, permitted wastewater discharges and other waste disposal sites, improper handling of hazardous materials,
urban storm water runoff, or other types of non-point source contamination such as runoff produced by agricultural
activities and land clearing for development. Your drinking water source(s) is listed in Table 1. Protecting your drinking
water from becoming contaminated is a wise investment in public health and your community's future.

Assessment Report Contents
This assessment report includes the following sections:
Section 1: Assessment Area Delineation
Section 2: Potential Contaminant Source Inventory and Map
Section 3: What is a Susceptibility Rating?
Section 4: Reviewing Your SWAP Results
Section 5: Maps, Tables and Figures for your Drinking Water Source(s)
Section 6: North Carolina's SWAP Approach
Section 1: Assessment Area Delineation
The area delineated for your well(s) for the purpose of this assessment is the contributing area for the well(s). When a
well is pumped, it begins to influence groundwater that is flowing through the subsurface and towards the well. The
pumping of the well creates a contributing area around the well that supplies water to the well. This is the area through
PWS ID: NC7065039 Page 1 of 23 September 10, 2020
which contaminants, if released to the environment, can be reasonably expected to move through the ground and reach
the well.
Section 2: Potential Contaminant Source Inventory and Map
The potential contaminant source inventory map shows the delineated area for your drinking water source(s). This is the
area where potential contaminant sources, if released to the environment, could reasonably be expected to be a risk or a
potential for contamination of your drinking water supply. A PCS in this assessment report is a facility or site regulated
under a state or federal regulatory program. These facilities are identified in electronic databases that contain location
information for each facility. Only databases that include statewide information were used for this source water
assessment. Included in this report are:
1) A table of any PCS identified within the delineated assessment area; and
2) A map of the delineated assessment area showing PCSs, roads, jurisdictional boundaries and other pertinent
information.
It is important to note that the PCSs identified in this report are only potential sources of contamination to your drinking
water source. Environmental contamination is not likely to occur if harmful contaminants are managed properly.
Section 3: What is a Susceptibility Rating?
In North Carolina the susceptibility of any drinking water source is based on two components, a contaminant rating and
an inherent vulnerability rating. Your drinking water source(s) was assigned a qualitative susceptibility rating of higher,
moderate or lower based on the results of the contaminant rating and inherent vulnerability rating process as described
in the following paragraphs.
Susceptibility Rating
The final susceptibility rating for your drinking water source(s) is determined by combining the contaminant rating and
the inherent vulnerability rating. More detailed information on the susceptibility rating process can be found in Section
6 of this report.
Contaminant Rating
The contaminant rating for your drinking water source(s) was determined based on the number and location of PCSs
within the delineated area. Each PCS identified within the delineated area was assigned a risk rating of higher, moderate
or lower. The number of PCSs that occur within the delineated area was determined and a contaminant rating of higher,
moderate, or lower was assigned to your drinking water source(s).
Inherent Vulnerability Rating
The inherent vulnerability rating of your well(s) refers to the geologic characteristics or existing conditions of the well
and its delineated assessment area. These characteristics include aquifer rating, unsaturated zone rating and well
integrity/well construction rating. The aquifer rating is an assessment of the water transmitting characteristics of the
aquifer. The unsaturated zone rating is an assessment of the likelihood that contaminants from surface and shallow
sources will follow the path of aquifer recharge and reach the water table. The well integrity/construction rating is an
assessment of the quality of the construction of the well. An inherent vulnerability rating of higher, moderate or lower
was assigned to your well(s).
PWS ID: NC7065039 Page 2 of 23 September 10, 2020
Table 2. SWAP Results Summary
Source Name Inherent Vulnerability Rating Contaminant Rating Susceptibility Rating
WELL #1 Higher Higher Higher
It is important to understand that a susceptibility rating of higher does not imply poor water
quality. Susceptibility is an indication of a water supply's potential to become contaminated
by the identified PCSs within the assessment area.

Section 6: North Carolina's SWAP Approach
This section of the report is a more detailed description of North Carolina's SWAP approach. This is a summary of
Chapter 2 of North Carolina's Source Water Assessment Program Plan.
Description of North Carolina's SWAP Approach
To meet the requirements of the 1996 SDWA Amendments, a Source Water Assessment was completed for
approximately 8,000 drinking water sources in North Carolina. A delineated area for assessment was established for
each drinking water source. An inventory of potential contaminant sources was conducted in each assessment area and
finally, a susceptibility rating was assigned to each drinking water source. Because of the scope of this task and the
limited time and resources available for completing the work, North Carolina's SWAP program efforts relies on
Geographic Information Systems (GIS) to effectively use information. GIS allows databases to be linked to points on a
map (e.g., public water supply sources, streams, geology, land use, roads, permitted waste disposal sites, Superfund
sites, etc.) and overlaid on top of one another.
Delineation of Assessment Areas for Surface Water Sources
For the purpose of performing source water assessments, "delineation" means defining what land area constitutes the
area contributing water to a public water supply source. The delineation of the source water assessment areas for
surface water sources was done in consideration and collaboration with the Water Supply Watershed Protection
(WSWP) Program. During the development of the WSWP program (final state rules adopted in 1992), the state worked
with local governments to determine the location of all surface water sources and existing land uses within the water
supply watersheds. This information, in conjunction with information on the types and location of wastewater
discharges, was used to determine the appropriate Water Supply Watershed Classification for more than 200 surface
water sources in the state. The watershed classifications, WS-I, WS-II, WS-III, WS-IV, and WS-V are based on the size
of the watershed, development activities, and allowable waste treatment and disposal practices.
All surface water sources were located on US Geological Survey 1:24,000 scale topographic maps. The water supply
watershed boundaries were delineated (except WS-V waters, which were delineated for the SWAP assessments by the
PWS Section), and the boundaries of the Critical Area, and in the case of most WS-IV water supply watersheds
Protected Areas (described below) were delineated.
For protection of the surface water sources in North Carolina, a segmentation of the water supply watersheds was
implemented through the WSWP rules. The entire drainage areas of WS-I water supply watersheds were delineated.
These watersheds are all publicly owned and no new development is allowed in these watersheds. These watersheds are
very small. Some are located within National Forests. Others are owned by a local government.
All WS-II, WS-III and WS-IV water supplies require delineation of a Critical Area which is defined as the area within
1/2 mile and draining to the normal pool elevation of a water supply reservoir, or 1/2 mile and draining to a water
supply intake in a river. For WS-II and WS-III water supplies, the remainder of the drainage area is subject to the
development standards of the WSWP rules and are implemented through local land use ordinances. WS-IV water
supplies, which are typically portions of major river systems, are segmented in a Critical Area (previously defined) and
a Protected Area. The Protected Area is defined as the area within 5 miles and draining to the normal pool elevation of a
reservoir or 10 miles upstream and draining to a river intake. In very few instances the WS-IV Protected Area
encompasses the entire drainage area due to the size of the watershed. In 1995, the state allowed local governments to
request that the 10 mile Protected Area boundary of a WS-IV water supply be measured "run of river" rather than using
a 10-mile arc linear measurement. Surface waters that are used by industry to supply their employees with drinking
water or waters formerly used as water supply are generally classified as WS-V. The WS-V waters are protected as
PWS ID: NC7065039 Page 14 of 23 September 10, 2020
water supplies and are typically located upstream of and draining to Class WS-IV waters. Land use restrictions do not
apply to WS-V waters under the WSWP rules.
Please note that for the purpose of the PWS Section's Source Water Assessments, delineation of WS-IV boundaries may
be different from the WSWP Program's delineation. The PWS Section watershed assessment areas include all land
draining to a drinking water source. However, the watersheds defined in accordance with the WSWP rules often
exclude land area draining to a source based on municipal or county jurisdictional boundaries. Please refer to the
WSWP program website for information on the regulations associated with their program and the land area affected by
their regulations.
Delineation of Assessment Areas for Public Water Supply Wells
The delineation of source water assessment areas for wells was in accordance with North Carolina's EPA approved
Wellhead Protection Program. The calculated fixed radius method was used to delineate assessment areas around each
well in the following areas: piedmont and mountains; the unconfined surficial aquifer of the coastal plain; and in the
semi-confined portions of the Castle Hayne aquifer with an estimated recharge rate of 250,000 gallons per day per
square mile. The aquifer-source-volume method was used for confined aquifers of the coastal plain. These methods are
described below. Well depth is the determining factor for a well to be considered confined. Well depths greater than 70
feet are considered confined.
Other assessment area delineation methods may be of interest to a PWS system in an effort to more accurately define
the area contributing water to the well. The state will review delineations provided by any PWS system that employs
acceptable alternative delineation methods. Resulting alternative delineation areas will be incorporated into the SWAP
if the state concludes that the use of the more sophisticated method is appropriate.
Calculation of the Contributing Area
The first step in delineating the assessment areas is to determine the size of the contributing area to the well. When a
well is pumped, it causes groundwater that is flowing through the subsurface to flow toward the well. The surface area
surrounding a well that delineates the area in which water entering the groundwater system at the water table eventually
flows to the well and discharges is known as the contributing area for the well. In this area, any contaminants released
to the environment that reach the water table, can reasonably be expected to move toward and possibly reach the well.
The calculated fixed radius method requires the pumping rate (Q) and the recharge rate (W) for the pumping well in
order to calculate the size of the contributing area. The contributing area is calculated as follows:
where:
Ac = contributing area in square miles,
Q = maximum daily pumping rate in gallons per day, and
W = average recharge rate in gallons per day per square mile.
The maximum daily pumping rate in gallons per day was determined from information on wells obtained from PWS
Section sanitary survey inspection forms, Division of Water Resources Local Water Supply plans, and information
supplied by system owners/operators. Where no information was available, an estimate of maximum daily pumping rate
was assigned based on hydrogeologic characteristics of the aquifer supplying water to the well.
PWS ID: NC7065039 Page 15 of 23 September 10, 2020
Size of the Assessment Area for Wells Using Calculated Fixed Radius Method
Estimates of the size of the contributing area can be obtained using the equation given above. However, because of the
complex nature of groundwater flow and contaminant transport, it is not possible to define exact contributing area
boundaries around each well. Two factors that affect the shape of the contributing area and its position and orientation
with respect to a pumping well are the hydraulic gradient and aquifer transmissivity. The variation in aquifer
transmissivity is important in determining the shape of the contributing area for a supply well. In areas where the
hydraulic gradient and the aquifer transmissivity are essentially the same in all directions, the shape of the contributing
area depends primarily on the hydraulic gradient. Where the water table is nearly flat, as near the water-table divide in
broad interstream areas of low relief, the contributing area is approximately circular. Where the hydraulic gradient is
moderate to steep, the contributing area is approximately elliptical, being oriented in the direction of groundwater
movement.
Due to limited availability of information on both hydraulic gradient and aquifer transmissivity, the assessment area for
each well was doubled. Therefore, the assessment area for each well is twice the size of the calculated contributing area
or:
Delineation of Assessment Areas for Wells in Confined Aquifers
Recharge to confined aquifers is much less than that to the surficial unconfined aquifer where the calculated fixed
radius method was used. If the calculated fixed radius method were applied to wells withdrawing water from confined
aquifers, the resulting assessment areas would be very large. With the exception of a portion of the Castle Hayne
aquifer, the aquifer-source-volume method was used for delineating assessment areas for wells determined to be
withdrawing water from highly confined and semi-confined aquifers. "Aquifer source volume" refers to the volume of
the source aquifer that supplies the withdrawals from a well for a specified period of time. This factor has been adopted
in many states for defining assessment areas for confined aquifers.
For the purpose of these assessments, the volume of aquifer that supplies ten years of withdrawals (i.e. the area
surrounding a well in which the time of travel to the well is ten years) was used. A ten-year period should be sufficient
to provide time to assess the potential impact of any groundwater contamination discovered within an assessment area
and for developing appropriate remediation and source water protection strategies for the water supply. For any well in
the coastal plain determined to be withdrawing water from a confined aquifer, the table below will be used to determine
the size of the assessment area.

Delineation of Assessment Areas for Water Supply Sources Classified as GWUDIs
Drinking water supplied by a well may include a surface water component. This is defined as Ground Water Under the
Direct Influence of Surface Water (GWUDIs). This term is used to indicate that water withdrawn from a well contains a
specific indicator or indicators (e.g., giardia) of the presence of a surface water component. The delineated area for a
PWS well classified as a GWUDI well will be the combined area of a circle based on the calculated fixed radius method
and the resulting upgradient watershed of the intersected surface water. Segmentation of the resulting watersheds was in
accordance with the most appropriate water supply watershed classification scheme.
Delineation for Water Supply Sources Classified as Springs
Springs can be defined as areas where the water table intersects the ground surface. Ground water may have flowed
many miles before appearing on the surface to form a particular spring. The delineated area for a drinking water source
classified as a spring was defined as the entire watershed area upgradient of the spring. Segmentation of the resulting
watersheds was in accordance with the most appropriate water supply watershed classification scheme.
Susceptibility Rating Methodology
The state determined that the overall susceptibility rating for each drinking water source should be based on two key
components, a contaminant rating and an inherent vulnerability rating. Inherent vulnerability refers to the physical
characteristics and existing conditions of the watershed or aquifer. A contaminant rating refers to an evaluation of the
number and location of potential sources of contamination. The contaminant rating and inherent vulnerability
methodologies are explained below.
Contaminant Rating Methodology
The contaminant rating for each water supply source was determined based on the number and location of potential
contaminant sources (PCSs) within the delineated area. The delineated area for the drinking water source encompasses
the area where PCSs, if released to the environment, could reasonably be expected to be a risk or a potential for
contamination of the drinking water supply. A PCS in this assessment report is a facility or site regulated under a state
or federal regulatory program. These facilities are identified in electronic databases that contain location information for
each facility. Only databases that include information statewide were used for this source water assessment. Each PCS
identified within the delineated area was assigned a risk rating of higher, moderate or lower. The number of PCSs that
occur within the delineated area was determined and a Contaminant Rating of higher, moderate or lower was assigned
to each drinking water source.
Contaminant Rating for Ground Water Sources
For each ground water source, define an inner Zone A with an area equal to half the area of the delineated assessment
area. Using Table 2, determine the number of PCSs that occur within each risk category according to their location,
either in Zone A or in the remaining delineated area. Determine the Contaminant Rating of higher, moderate or lower
for each well by adding the totals for each risk category.

score is 6.
Determine the Contaminant Rating for each well as follows:
Higher (6 - 4)
Moderate (3 - 2)
Lower (< 1)
Contaminant Rating for Surface Water Sources
Because the WSWP rules prohibit development in these watersheds, the existence of one PCS in the delineated area of a
drinking water source located in a WS-I watershed will result in a contaminant rating of higher.
Using Table 3 for WS-II and WS-III watersheds, or Table 4 for WS-IV and V watersheds, determine the number of
PCSs that occur within each risk category (i.e., lower, moderate or higher risk) and within each delineated assessment
area (e.g., critical area, protected area, etc). Determine the Contaminant Rating for each surface water PWS source by
summing the totals for each risk category.

Inherent Vulnerability Rating Methodology
The inherent vulnerability of a well or surface water source refers to the characteristics or existing conditions of the
well or surface water source and its delineated assessment area. Several factors were evaluated for both groundwater
and surface water sources and included in the inherent vulnerability rating of each public water supply source. Each
drinking water source was assigned an inherent vulnerability rating of higher, moderate or lower.
Inherent Vulnerability Rating for Wells
The characteristics included for assigning an inherent vulnerability rating for wells are aquifer rating, unsaturated zone
rating and well integrity/well construction rating. The aquifer rating is an assessment of the water transmitting
characteristics of the aquifer. The unsaturated zone rating is an assessment of the likelihood that contaminants from
surface and shallow sources will follow the path of aquifer recharge and reach the water table. The well
integrity/construction rating is an assessment of the quality of the construction of the well. A brief description of each
factor follows:
PWS ID: NC7065039 Page 19 of 23 September 10, 2020
Aquifer Rating
The aquifer rating is a qualitative assessment of the water transmitting characteristics of the aquifer. Relative
differences in aquifer vulnerability were based on a review of relevant literature, expert opinions, and confirmed with
historical data. Factors considered in rating aquifer vulnerability include hydraulic conductivity, degree of confinement,
dilution, and sorption potential. The attenuative capacity of the unsaturated zone is not considered in the determination
of aquifer ratings. Table 5 summarizes the aquifer-rating scheme used for these assessments.
Well depths determined whether a well was considered unconfined, deep confined or shallow confined for these
assessments. Wells less than or equal to 70 feet deep were considered to be withdrawing water from an unconfined or
surficial aquifer. Wells greater than 70 feet but less than 180 feet deep were considered to be withdrawing water from a
shallow confined aquifer. Wells greater than 180 feet deep were considered to be withdrawing water from a deep
confined aquifer.

Fractured Rock Aquifers Higher
Other:
Metamudstones and Meta-argillites of the Carolina Slate Belt Higher
Areas with Wells Cased to Less Than 20 Feet Higher
Groundwater under the Direct Influence of Surface Water Higher

Unsaturated Zone Rating
The state, in cooperation with the United States Geological Survey (USGS), developed the unsaturated zone rating
methodology. The USGS Water-Resources Investigations Report 99-4283, "Methods of Rating Unsaturated Zone and
Watershed Characteristics of Public Water Supplies in North Carolina" describes the methodology. The unsaturated
zone rating is the combination of selected factors that contribute to the likelihood that contaminants from surface and
shallow sources will follow the path of aquifer recharge and reach the water table. Contributing factors, in the form of
GIS spatial data layers, include land use/land cover, vertical hydraulic conductance of the unsaturated zone, and
land-surface slope. Vertical hydraulic conductance measures the capacity of the unsaturated zone to transmit water from
land surface to water table. Land-surface slope and land cover influences the amount of precipitation that infiltrates into
the subsurface. Land use describes the activities that take place on the surface or in the shallow subsurface and the type
of contaminants that may be present as a result of those activities (i.e., "non-point source" potential contaminant
sources).
Well Integrity/Construction Rating
The integrity of well construction can vary widely, depending on details such as casing depth, grouting depth, well
materials and driller knowledge. However, these details are not always available for assigning SWAP assessment
ratings. In 1994 and 1999 there were important rule changes that greatly improve the quality of the well construction
PWS ID: NC7065039 Page 20 of 23 September 10, 2020
standards. Therefore, the SWAP assessments use well construction and approval dates as a surrogate to construction
details to assign a well construction / integrity rating. For wells that construction and approval date is not available, the
well construction/integrity rating defaults to Higher.
Table 6 summarizes the characteristics evaluated and rated for the inherent vulnerability for each PWS well. Each well
was assigned an inherent vulnerability rating of higher, moderate or lower:

Aquifer Rating 10 5 -1
Unsaturated Zone Rating 10 5 1
Well Integrity/Construction Rating 5 3 1
Totals 25-18 17-15 14-1
Inherent Vulnerability Rating for Surface Water Sources
The inherent vulnerability of a surface water source refers to the characteristics and existing conditions of the source
and the delineated assessment area (watershed). The characteristics included for assigning an inherent vulnerability
rating are water supply watershed classification, surface water source location, raw water quality, and the watershed
characteristics rating. The watershed classification is based on the size of the watershed, development activities, and
allowable waste treatment and disposal practices. The surface water sources were characterized based on whether they
are located in streams, large multi-purpose reservoirs, or small water supply reservoirs. The raw water quality rating is
based on recorded turbidity and total coliform values over a twelve month period. The watershed characteristics rating
is an assessment of the likelihood that contaminants will follow the path of overland flow or shallow subsurface flow to
a surface water source. A description of each factor follows:
Watershed Classification
In North Carolina, all surface water sources are located in water supply watersheds that are classified as either WS-I, II,
III, IV, or V. The Water Supply Watershed Protection rules required that all local governments having land use
jurisdiction within water supply watersheds adopt and implement water supply watershed protection ordinances, maps
and a management plan. All of these ordinances are in place and have been deemed to be in compliance with the
statutory requirements. The inherent vulnerability ratings for watershed classification are based on differences between
watershed classes, including size of the watershed, development activities, and allowable waste treatment and disposal
practices.
Surface Water Source Location
All surface water sources are located in streams, large multi-purpose reservoirs (Class 3), or small water supply
reservoirs (Class 1 or 2). The inherent vulnerability ratings for surface water source location are based on differences
between the reaction time for a water plant in the case of a contamination event or spill in a stream versus a reservoir
and includes the allowable activities on surface water reservoirs (i.e., single use versus multiple uses allowed).
Raw Water Quality
The likelihood of the presence of Cryptosporidium and other water-borne microorganisms increases when turbidity is
high. Therefore, turbidity and total coliform bacteria are good indicators of raw water quality. The Area Wide
Optimization Program (AWOP) within the PWS Section has developed a ranking system for surface water treatment
PWS ID: NC7065039 Page 21 of 23 September 10, 2020
plants based primarily on these two parameters. This ranking system, with some minor modifications, has been adopted
by SWAP in order to assign a raw water quality rating to each surface water source.
The AWOP ranking system is based on the treatment plant's raw, settled and finished water turbidity and coliform
levels along with violations of MCLs and treatment techniques. Raw, settled and finished water samples are collected
daily and compiled in a monthly report, commonly referred to as a MOR (monthly operating report). The AWOP
ranking system first totals the number of months in a year that specific levels of turbidity and coliform are exceeded
and/or the number of months certain violations occur. The monthly totals are then multiplied by a weighting factor to
balance the relative importance of these parameters. These numbers are then totaled for the year and are considered the
water treatment plant's total score.
Because the purpose of SWAP is to assess sources of drinking water supply and not how well water plants treat their
water, SWAP only uses the raw water scores for turbidity and coliform from the AWOP ranking system. The total raw
water quality scores were divided into three categories of vulnerability: Higher, Moderate and Lower. The AWOP
ranking system is for surface water treatment plants and not individual surface water sources. Therefore, in the case
where more than one source is used by a treatment plant, the plant's raw water quality rating was initially assigned to all
of the plant's sources. Upon review by the regional office staff some of the ratings were then adjusted based on their
extensive knowledge of the surface water sources in their area.
Watershed Characteristics Rating
The state determined the watershed characteristics ratings of each surface water source in cooperation with the USGS.
The USGS Water-Resources Investigations Report 99-4283, "Methods of Rating Unsaturated Zone and Watershed
Characteristics of Public Water Supplies in North Carolina" describes this methodology. The watershed characteristics
ratings were based on the combination of selected factors that may contribute to the likelihood that contaminants follow
the path of overland flow and reach the surface water source. Contributing factors, in the form of GIS spatial data
layers, include average annual precipitation, land cover, land use, land-surface slope and groundwater contribution.
Precipitation is the source of water transported overland to a stream or lake. Land-surface slope and land cover
influence the amount of precipitation that infiltrates into the subsurface. Land use describes the activities that take place
on the surface or in the shallow subsurface and the type of contaminants that may be present as a result of those
activities (i.e., non-point source potential contaminant sources). Ground-water contribution is the effect of ground water
on surface-water quantity and quality. For these assessments the ground-water contribution is derived from the
unsaturated zone rating described in the ground water inherent vulnerability section of this report. Table 7 includes the
characteristics that were evaluated and rated for the inherent vulnerability for each surface water source:

** - Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate cancer risk or hazard quotient. Lead concentrations are compared to the EPA screening level of 800
mg/kg for commercial/industrial soil.
