Charlotte, Mecklenburg County, NC
Dear Ms. Bramble,
Under authority of the Comprehensive Environmental Response, Compensation, and
Liability Act of 1980 (CERCLA) and the Superfund Amendments and Reauthorization Act of
1986 (SARA), the NC Superfund Section conducted a Site Reassessment at the above site. The
purpose of this investigation was to collect information concerning conditions at the site
sufficient to determine the need for additional CERCLA/SARA or other appropriate evaluation.
Based on the results of this investigation, this site is recommended for No Further Remedial
Action Planned (NFRAP) designation under CERCLA.
The scope of this investigation included reviews of a 1984 CERCLA Site Inspection,
private contractor site investigations conducted at the site property and documents produced by
and for the NC DEQ Brownfields program. NC and Mecklenburg County geographic
information system (GIS) data were reviewed to identify potential groundwater receptors near
the site. Field investigation included passive soil gas (PSG) and emergent surface water
sampling, due to historical storage and use of chlorinated volatile organic compounds (cVOCs)
at the site property (see Appendices A and B).
Site Description, Operational and Regulatory History and Waste Characteristics:
Site Description:
The site is a former textile and textile equipment manufacturing facility located at 2000
South Boulevard, Charlotte, NC 28803. The northeast end of the site is at the intersection of
South Boulevard and East Tremont Avenue. Geographic coordinates at the approximate
contaminant source area are 35.20891o N Latitude and 80.86145o West Longitude (Refs. 3, 4;
Figs. 1, 2, 3).

The site property currently consists of two adjoining parcels, totaling 9.78 acres. The
southern parcel, currently 2100 South Boulevard, was historically part of the northern 2000
South Boulevard parcel. The northern parcel currently contains the (one-to-two-story) Atherton
Mill Shopping Center. The southern parcel is covered by a six-story apartment complex,
ground-floor retail stores and a five-story parking garage. The site is bounded by a railroad and
former textile mill to the northwest and by South Boulevard to the east and southeast, beyond
which lie commercial properties. Commercial properties also border the site to the south (Refs.
4, 5, 6, 7).
On-site ground surface elevation ranges from 743 to 760 feet. A low topographic ridge
runs north through the eastern portion of the site, before curving into a “saddle” to the northeast.
This topography divides two drainages: a northward tributary drainage toward Irwin Creek, to
the north of the site, and a southeastward drainage toward Dairy Branch and Upper Little Sugar
Creek to the east of the site (Refs. 3, 4, 10; Figs. 1, 3).
Site Operational and Regulatory History and Waste Characteristics:
Site operation by Parks-Cramer began in 1918-1919. However, a review of historic
Sanborn Fire Insurance Maps in 2006 indicated that a cotton mill (Atherton Cotton Mill)
operated there prior to that time, possibly as early as 1896. Parks-Cramer operated on the
northern parcel, manufacturing air handling equipment and hoisting systems for the textile
industry. Operation expanded south in the 1960s and 1970s, eventually including approximately
12 acres and nine structures. A separate motorboat service and repair shop operated on the
southern parcel from 1957 to 1991 (Refs. 5, 6, 8, 9).
In 1988, Parks-Cramer sold their operation to Flakt, Inc., and South Boulevard Properties
Inc. (SBP) was created as site owner/manager. Flakt was purchased by Luwa Bahnson, which
leased the site until 1992, when manufacturing activities ceased. In 1993, the main former
Parks-Cramer structure on the northern parcel was renovated for use in retail sales and as office
space, and secondary structures there were removed. In 1996, a former Atherton Mills textile
structure directly west of the southern parcel was renovated into office/loft-condominium units
(Refs 5, 6, 8). In 2018, the “Crane building”, located at the north end of the southern parcel, and
two other structures to the south, were demolished for redevelopment into the current
residential/commercial complex (Refs. 4, 6, 7). Both properties are currently owned by Atherton
Mill (E & A), LLC (Atherton Mill) (Ref. 3)
From 1962 to 1988, Parks-Cramer Co. operated a vapor degreasing unit at their facility
on the northern parcel. The degreasing unit, used to clean/prepare metal parts for paint
application, was located in the western interior of the structure that currently operates as the
shopping center. The primary solvents used in the degreasing unit consisted of trichloroethene
(TCE), and (after 1976) 1,1,1-trichloroethane (TCA). Solvents were stored in a steel
aboveground storage tank (AST). Solvent use was estimated to range from 1000 to 2000
gallons/year (Refs. 6, 8, 9).

During summer months, waste solvent, applied by hand-pump sprayer, was reportedly
used to control weed growth along the northwest property line of the northern parcel, adjacent to
the railroad embankment. The spraying continued until 1979, when promulgation of the
Resource Conservation and Recovery Act (RCRA) led to the facility shipping its waste solvents
off site for recycling. As a result of the reported disposal practice, Parks-Cramer was included
on the (then) NC Department of Natural Resources and Community Development’s Emergency
Response and Remedial Information Systems (ERRIS) list (Refs. 6, 8).
In 1984, then NC Division of Human Resources conducted a CERCLA Site Inspection
site visit. However, due to the urban setting and absence of local groundwater use, the Division
recommended the site to the EPA as a low priority for further action (Ref. 9).
As part of the 1988 property transaction, SBP contracted an environmental investigation
at the site. The investigation included completion of hand augered test borings, installation of
monitoring wells, and collection of groundwater samples from the above. Investigation focused
on the area adjacent to the former degreasing unit, and along the northwest portion of the 9-acre
property. Sample analysis detected chlorinated volatile organic compounds (cVOCs), including
1,1,1-TCA, 1,2-dichloroethane (DCA), 1,1-DCA, 1,2-dichloroethene (DCE), 1,1-DCE, TCE and
methylene chloride, in one or more groundwater locations. Results demonstrated that TCE and
1,1,1-TCA were the most prevalent contaminants on site. The former vapor degreasing unit was
identified as the primary contaminant source, with the weed-spraying area being secondary (Ref.
6). Subsequently identified sources included: 1) a storm drain outfall to a ditch along the
adjacent railroad, and 2) an adjacent former drum storage area (Ref. 8).
In response to the discovery of groundwater contamination at the site, the (then) NC
Department of Environment, Health and Natural Resources, Hazardous Waste Section (HWS)
issued a Compliance Order (Docket #89-172) to SBP. A RCRA Facility assessment had
identified three Solid Waste Management Units (SWMUs) and one Area of Concern (AOC):
1.SWMU 1: TCE contaminated surface soil along a loading dock and approximately 38
feet of rail spur, north-northwest of the Atherton Mill building. Corrective action in 1991
consisted of excavating and removing contaminated railroad cross ties and soil for offsite
incineration (Refs. 8, 10).
2.SWMU 2: TCE and TCA contaminated drainage ditch along the main railway, west of
the Atherton Mill building. Possible contributors included an adjacent drum storage area,
a storm drain outfall and/or historical waste solvent spraying for weed control. Corrective
action, begun in 1992, included vacuum extraction of soil vapor, which reduced the area
of contamination to the immediate vicinity of the drum storage and drain outfall (Refs. 8,
10).

3.SWMU 3/Waste Management Unit 1: The former Vapor Degreasing Unit on the north
parcel, with associated piping, storage, concrete containment vault and underlying
contaminated soil. Corrective Action in 1990-1991 consisted of removing the degreasing
equipment and filling/sealing the containment vault. Vacuum extraction in 1991
addressed the underlying contaminated soil, confirmed by soil sampling in 1993 (Refs. 8,
10).
4.AOC 1: Isolated solvent (acetone, 2-butanone) spill location north of the boat service
facility on the southern parcel. Follow-up assessment determined that the constituents
were no longer detectable there (Refs. 8, 10).
In May 1996, SBP contractors submitted an initial Part B Post-Closure Permit
Application to the NC Department of Environment and Natural Resources (NCDENR) HWS.
The Application reported that soil contamination in SWMUs 1 and 3, and the AOC, had been
effectively remediated. From 1997 to 1999, SBP contractors conducted additional soil
investigations at SWMU 2. In 1997, as an addendum to the Application, SBP contractors
completed an initial baseline risk assessment to evaluate contaminant fate and transport to
evaluate potential risk to human health and the environment. The Assessment included a
groundwater flow and solute transport model (Refs. 8, 10).
In 1990, SBP voluntarily installed and operated a recovery system to pump and treat
cVOC contaminated groundwater at the site. Highest groundwater cVOC concentrations (93.4
mg/L 1,1,1-TCA; 389 mg/L TCE; 8.29 mg/L PCE) were detected in one monitoring well (MW-
14), screened in weathered bedrock at approximately 50 feet depth below ground surface. Total
VOC concentrations in other monitoring wells ranged from non-detect to 40 mg/L. The treated
groundwater was discharged, under permit, to the Charlotte POTW as non-hazardous material
(Ref. 8). SBP contractors had proposed Alternative Concentration Levels (ACLs) and
downgradient Allowable Exposure Levels (AELs) for site groundwater contaminants. The NC
HWS accepted the ACLs/AELs on the condition that groundwater monitoring confirmed
groundwater solute transport model predictions that had previously been submitted by SBP
contractors (Ref. 10).
In August 2000, the Charlotte Mecklenburg Utilities Department announced that it would
no longer accept treated groundwater, and so the on-site groundwater recovery was discontinued
in April 2001. As part of a Modified Post-Closure Plan, SBP then proposed decommissioning/
removing the groundwater recovery system, plus removal of the soil vapor recovery systems that
had previously operated at the SWMUs/WMU 1. SBP proposed continued semi-annual sampling
at selected monitoring wells for the following three years, to be extended by two annual events if
requested by the NC HWS. SBP submitted a survey plat to the Mecklenburg County Planning
Commission and recorded a notation on the deed to the property, both notifying of the location
and dimensions of former SWMU 1 (Ref. 10).

In 2004, the HWS informed SBP of a change in previously agreed conditions for the site
being released from the RCRA program: Preparation of a Technical Impracticability (TI)
evaluation would be required for no further site remedial and/or investigation activities to be
required under RCRA. SBP contractors submitted a report contending that 1) the high
concentrations of cVOCs in site groundwater indicated the likelihood that dense non-aqueous
phase liquid (DNAPL) was present in the subsurface, and that 2) the presence and behavioral
characteristics of the DNAPL would preclude the likelihood that available technologies could
sustainably remediate site groundwater to applicable standards. SBP additionally created an
Area of Regulated Groundwater Usage under the provisions of Mecklenburg County
groundwater well regulations (Ref. 11). In response, in November 2005, the NC HWS agreed to
deny the Post Closure Permit, having determined that SBP had satisfactorily demonstrated TI
and had also demonstrated adequate protection of potential (groundwater) receptors (Ref. 12).
In February 2006, South Boulevard Properties filed a Declaration of Perpetual Land Use
Restrictions (LURs) with the Mecklenburg County Register of Deeds. The restrictions
prohibited any groundwater use, called for state-compliant abandonment of all existing wells,
prohibited any additional well drilling or excavation/subsurface construction without written
permission from the NC HWS, and required any basements to be vented according to State and
local building codes (Ref. 13).
In August and September 2006, Edens & Avant Investments Limited Partnership
submitted a Letter Of Intent (LOI) and affidavit seeking eligibility for a Brownfields agreement
with the State of NC. The application proposed commercial, retail and residential redevelopment
of the project site (2000-2140 South Boulevard); the Brownfields program affirmed the site’s
eligibility for entry and continued evaluation under the program (Ref. 14). However, the site
continued to operate under LURs with the NC HWS Facility Management Branch until 2016
(Refs. 15, 16).
In 2012, contractors for Atherton Mill completed a sub slab vapor assessment, collecting
samples at twelve locations beneath the four structures then existing at the site. The structures
included (from north to south) the former Parks-Cramer structure (Building One), the “Crane
Building” (Building Two), a former motorboat service shop (Building Three) and a fourth
structure (Building Four) on the southern parcel. The highest cVOC concentrations (TCE, PCE,
1,1,1-TCA) were detected beneath the northern portion of Building One and beneath the central
to northwest portion of Building Two, in proximity to previously identified source areas (Ref.
17).

Contractors for Atherton Mill completed five indoor air quality assessment events in
April and July 2013 and in January, June and September 2014. Initial events consisted of
collecting samples from four locations in Building One and two locations in Building Two.
Outdoor air samples were also collected as background. The final event focused on previously
unsampled interior sections of Building One, and also evaluated performance criteria for
installation of a sub-slab depressurization system (SSDS) for soil vapor mitigation beneath the
structure (Refs. 18, 19, 20).
Results for the January 2014 indoor air sampling event were not available on file for
review. Contaminants detected by the other four indoor air sampling events in Building One
included aromatic petroleum compounds and TCE. The aromatic compounds were attributed to
wood-block flooring material, which the contractor recommended for removal. A single indoor
air sample from Building One contained 1,760 µg/m3 TCE, while indoor air sample TCE results
from other sections of Building One ranged from non-detect to 46.4 µg/m3 (Refs. 18, 19, 20).
Indoor air TCE concentrations exceeded EPA health-based cancer and non-cancer
groundwater benchmarks in the majority of the (21) samples from Building One and in half of
the (8) samples collected from Building Two. However, the majority of indoor air TCE
concentrations did not exceed three times the concentrations detected in concurrent
outdoor/ambient air samples (Refs. 2, 18, 19, 20).
In January 2016, contractors for Atherton Mill submitted a draft Vapor Intrusion
Mitigation System (VIMS) Construction Package for Building One to the NC Brownfields
program. The package described retrofitting the structure with a subfloor ventilation system
beneath new, 4-inch concrete floor slabs, with wind-drawn outdoor vent pipes (Ref. 21).
In 2017, contractors conducted a two-phase soil screening investigation preparatory to
demolition of Building Two (“The Crane Building”) and the other two structures on the southern
parcel. A total of 90 borings were completed beneath the foundation and in proximity to the
existing vacant Building Two, with soil samples collected at 1-foot depth intervals and then field
screened by flame ionization detector (FID). Only one sample produced a FID reading
exceeding 10 ppm; laboratory analysis of the sample detected semi-volatile organic compounds
and arsenic, but not VOCs (Ref 22). Following demolition and removal, additional test pit
excavation took place in November 2017. Under the Brownfields agreement, a Soil Restriction
Area/Vapor Intrusion Requirement Zone was established on site, within which any new building
construction was required to include installation of vapor mitigation measures (Refs. 15, 23, 24).
The extent of identified cVOC groundwater contamination includes multiple properties to
the north and northwest of Parks-Cramer:

Investigations at Adjacent Properties:
•Mitchell & Becker Site (M&B,1928 South Boulevard; NONCD0001041): Former iron
works facility (~1940 to 1996) located northeast across Tremont Avenue from Parks-
Cramer. Currently in commercial (retail; restaurant) use. Groundwater sampling (1996-
1997), detected TCE contamination (2.7 µg/L). NC HWS referred site, post-closure, to
the NC Superfund Section IHSB. In 2014, at property owner’s request (citing Parks-
Cramer as possible source), IHSB changed M&B status from Priority Site to No Further
Action (Refs. 25, 26). TCE groundwater concentration was less than EPA Target
Groundwater Vapor Intrusion Screening Level (VISL) for commercial use (Ref. 27), and
likely represented northeast edge of Parks-Cramer groundwater contaminant plume.
•Camden Square (1930 Camden Road): Former Package Products facility located north,
diagonally across West Tremont Avenue from Parks-Cramer. Property entered into NC
Brownfields agreement (1998; Project No. 01001-97-060), with LURs including
prohibition of groundwater use. In 2017, contractors summarized prior sub-slab soil gas
sampling results and proposed additional indoor air evaluation, toward design of
proposed active soil vapor intrusion mitigation system (VIMS) beneath existing property
structures (Refs. 28, 29, 30).
•Former Fergusen Enterprises Property (101 West Tremont Avenue): Former warehouse
and showroom located directly northeast of Parks-Cramer. Demolished and redeveloped
as multi-story commercial and residential complex under NC Brownfields agreement
(Project No. 10009-06-060). Due to proximity to Parks-Cramer, with highly concentrated
cVOC groundwater contamination, LURs specified that construction include installation
of a vapor barrier/VIMS (Ref. 31).
•Charlotte Oil and Fertilizer Works (2151 Hawkins Street): Located northwest, across
railroad from the Parks Cramer. Under NC Brownfields agreement (Project No. 22055-
18-060), site has been redeveloped into 17-story mixed-use structure. In 2021, NC
Brownfields personnel monitored pre-installation of a vapor barrier and VIMS at the
construction site (Ref. 32).
•“Hot Sake” Recording Studio: Small structure located on Hawkins Street between former
Charlotte Oil construction site and former Fergusen property (Ref. 4). No sampling
investigations on record. Commercial property, anticipated to be inhabited on an
intermittent basis.

•Former Dynatech Industries (2187 Hawkins Street): Former chrome plating facility (1973
to 1984) located approximately 600 feet southwest (across-gradient) from Parks-Cramer,
Groundwater sampling (1991) revealed TCE (8 to 2,100 µg/L), PCE (300 µg/L) and 1,1-
DCE (16 µg/L). Groundwater remediation was initiated under a state administrative order
in 1992 (Ref. 8)
Investigations at Properties Farther Downgradient:
•Camden Square 2nd Amendment (1932 Hawkins Street): Located west of Camden Square
and 0.15-mile northwest of Parks-Cramer. Amendment 2 to Camden Square Brownfields
agreement (NC Brownfields Project No. 09060-05-060). Thirteen-story (0.3 acre)
commercial and residential structure, and multi-deck parking garage, constructed (2019)
on larger (2.95-acre) property between Hawkins Street and Abbott Street. Mixed-use
construction included installation of VISL. Additional commercial/residential
condominium structures constructed on western edge of property, on east side of Abbott
Street. Brownfields LURs specify: 1) Any slab-on-grade construction requires State-
approved vapor barrier and/or VIMS installation, and 2) any other inhabited construction
requires active mechanical ventilation system (Refs 33, 34).
•Kale-Bindex (Doggett Street/Helix Way): Five-Building residential condominium
complex (NC Brownfields Project No. 16028-12-060). Located 0.1-mile northwest of
Parks-Cramer. Pre-construction TCE groundwater concentrations (2011) ranged from 41
µg/L (west) to 6,200 µg/L (east). Soil gas assessment (2012) detected TCE (up to 60,000
µg/m3), PCE (up to 4,700 µg/m3) and 1,1-DCE (up to 3,800 µg/m3). LURs specified
installation of VIMS at all structures designed for ground-level occupancy (Ref. 35).
•Doggett Street and West Tremont Avenue site (305 Doggett Street): Located 0.16- mile
west-northwest of Parks-Cramer. Recent NC Brownfields-eligible site. Chlorinated VOC
VI potential but no cVOC groundwater or soil gas data on file (Ref. 36).
•Carolina Foundry (224-232 West Tremont Avenue): Located 0.15 mile west-northwest of
Parks Cramer. Former aluminum, brass and copper casting facility (NC Brownfields
Project No. 20054-16-60). Groundwater sampling for VOCs (2017) detected only
methylene chloride and styrene; soil gas sampling (2017) detected PCE (“J’d” single-
digit µg/m3) but no TCE or DCE (Ref. 37).

•Camden Square Addition (West Worthington Avenue & Tryon Street, SE): Located 0.22-
mile northwest of Parks-Cramer. Amendment 1 to Camden Square Brownfields
agreement (NC Brownfields Project No. 05001-01-060). Comprehensive Site Assessment
(2001) documented TCE groundwater contamination (up to 680 µg/L (1995)), plus
possible contaminated groundwater discharge (570 µg/L) via northwest-flowing storm
water culvert toward South Tryon Street. Survey plat (2001) notes document TCE
groundwater contamination (220 µg/L (2000)) (Refs. 38, 39, 40).
•Hughes Supply: (South Tryon Street & Doggett street NE): Located directly south of
Camden Square Addition. Brownfields LURs specify no ground-level use other than
parking, pending completion of soil gas sampling/VIMS installation (Ref. 41).
•Palmers Automotive (1900 South Tryon Street/401 West Worthington Avenue: Located
north across Tryon Street from Camden Square Addition. Groundwater sampling (2016)
detected TCE (up to 260 µg/L) and PCE (up to 55 µg/L). Outdoor soil gas sampling
(2017) detected TCE (up to 1200 µg/m3), PCE (up to 1600 µg/m3), additional cVOCs and
petroleum-related VOCs. Brownfields LURs prohibit groundwater use and require that
all enclosed construction certify protection from, or completion of mitigation measures
against, VI. (Ref. 42). Detections of TCE and PCE in groundwater and soil gas occurred
primarily in the upgradient (southeastern) portion of the property; groundwater and soil
gas results to the north/west were either non-detect for cVOCs or were less than
residential VISL Target values (Refs. 27, 43). This Brownfields site is the farthest
downgradient within the known/suspected cVOC migration pathway from Parks-Cramer
(Fig. 2).
•City block between Camden Road, Hawkins Street, West Street and West Worthington
Avenue: Located 0.14 to 0.2-mile north of Parks-Cramer. Three overlapping Brownfields
projects, comingled: DCC Apartments RN (No. 1910-50-060); Terminix (No. 24048-20-
060); West Worthington Avenue site (No. 12025-08-060). Groundwater sampling on
southwestern parcel (2008) detected PCE (up to 9.69 µg/L), TCE (up to 196 µg/L) and
1,1-DCE (up to 49.7 µg/L). Soil gas sampling on south-central parcel (2008) detected
VOCs but no PCE, TCE or DCE. Soil gas sampling (3 points, NW-SE) across block
(2015) detected PCE (up to 10 µg/m3) and TCE (up to 1.8 J µg/m3). Soil gas sampling on
southwest parcel (2016) detected PCE (up to 41 µg/m3) and TCE (up to 19 µg/m3).
Southeastern quarter of block was redeveloped as multi-story mixed-use commercial/
residential complex; southwestern quarter (where cVOC contaminants were detected)
was redeveloped as a multi-level open-air parking garage (Refs. 4, 44, 45, 46, 47).

Groundwater Migration Pathway and Targets:
Charlotte NC lies within the Charlotte lithotectonic belt, which consists primarily of
igneous and metamorphosed igneous bedrock. Bedrock beneath the site and downtown Charlotte
is locally mapped as weakly foliated Devonian age granodiorite and related granitoids. Fractures
within the local bedrock are mainly oriented either east to west, dipping south, or south-southeast
to north-northwest, dipping west-southwest (Refs 6, 11, 48).
Soil at the site is mapped as Cecil-Urban Land complex consisting mainly of yellow-red
sandy clay loam, much of which has been disturbed by cutting/filling/grading. On-site
subsurface explorations encountered 0.5 to 1 feet of silty sand, underlain by stiff to very stiff red
clayey silt/silty clay to depth of 1 to 12 feet. The subsoil grades downward into fine sandy silty
saprolite and weathered bedrock, which occurs to depths of 10 to 40 feet and occasionally as
deep as 60 feet (Ref. 6).
Site hydrogeology is reported to be typical of the Piedmont: The unconfined aquifer
consists of the saturated porous zone of the saprolite, hydraulically connected to water-bearing
fractures in the underlying partially weathered and unweathered bedrock. In the porous saprolite
zone, groundwater elevation and flow direction generally reflects surface topography and
overland drainage. Groundwater migration in bedrock is typically controlled by spacing and
orientation of fractures. (Ref. 6).
Based on cumulative groundwater measurements, approximate depth to groundwater
beneath the site property ranges from 3 to 35 feet. Groundwater elevation data from both on- and
off-site monitoring well locations indicate that the potentiometric surface within both the
saprolite and weathered/fractured bedrock zones locally slopes to the north-to-northwest, away
from a northeast-southwest-oriented groundwater divide that follows South Boulevard (Refs. 3,
6, 8, 11, 49).
Analytical data from groundwater sampling at off-property monitoring wells indicate a
north/northwestward-migrating plume of cVOC contamination, consistent with the contaminated
portion of the site being located on the western side of the previously described
topographic/groundwater divide. Localized off-site “hot spots” of cVOC contamination have
also been identified at apparent sources along Hawkins Street, 250 feet west and 500 feet north
of the Parks-Cramer property, respectively. In 1995, the NC HWS acknowledged that these
latter areas of contamination likely represented co-mingling cVOC plumes from other industrial
sources, not attributable to the Parks-Cramer site (3, 6, 8, 11, 49).

The City of Charlotte supplies drinking water to residences and businesses within the city
limits. The city’s drinking-water source consists of surface water intakes along the Catawba
River. No public water-supply wells operate within a 4-mile radius of the Parks-Cramer site. A
well survey conducted during a previous investigation indicated that no private drinking-water
wells operated within a 1500-foot radius of the site, consistent with the local urban character
(Refs. 8, 50, 51; Fig 1). Based on the absence of proximal groundwater targets, the exposure
hazard posed by the groundwater migration pathway appears to be minimal.
Surface Water Migration Pathway and Targets:
The western majority of the site property, including known source areas of groundwater
contamination, lies within the Irwin Creek Watershed (Ref. 3). Previous investigations report
that (intermittent) runoff occurs in a drainage ditch between the site property and the adjacent
railway corridor to the west. Runoff from the northern portion of the railroad ditch discharges to
a storm drain which passes north beneath Tremont Avenue, then continues northwest.
Underground storm drains continue northwest and west beneath the Camden Square Addition
property and South Tryon Street, running parallel to West Worthington Avenue. Within the
northwestward drainage area, the probable point of entry (PPE 1) to perennial surface water
likely exists where stormwater and/or emergent groundwater discharges to an unnamed surface
tributary of Irwin Creek. This tributary begins at a storm drainage culvert within a property
parcel northeast of the intersection of Wilmore Drive and Wood Dale Trail, approximately 0.6
mile northwest from the site (a second, eastern tributary is mapped as joining the unnamed
tributary below the PPE, but the latter’s existence has been ruled out by field observations).
From the mouth of the 0.35-mile tributary, Irwin Creek flows south approximately three miles to
Sugar Creek. Sugar Creek continues approximately 24 miles to the Catawba River (Refs. 8, 52;
(Fig. 4A). Sugar Creek therefore contains the fifteen-mile surface water pathway target distance
limit (TDL).
Surface runoff from the (much smaller) eastern portion of the site reportedly enters storm
drains along South Boulevard and migrates eastward toward Dairy Branch, a tributary of Little
Sugar Creek. Within the southeastward drainage area, the PPE (PPE 2) to perennial surface water
exists where stormwater and/or emergent groundwater discharges to Dairy Branch. This tributary
begins at a culvert located between residences southeast of the intersection of East Tremont and
Lyndhurst Avenues, approximately 0.4 mile east from the site. Dairy Branch flows 1.44 miles
to Little Sugar Creek. Little Sugar Creek joins Sugar Creek several miles downstream from the
latter’s confluence with Irwin Creek (Refs. 4, 8, 51, 52; Fig. 4B).
No public surface-water intakes reportedly operate within the 15-mile TDL (Refs. 8, 50).
The nearest identified fishery for human consumption is a 6-acre pond located parallel to
Little Sugar Creek at Freedom Regional Park, approximately 1.44 miles downstream in the
eastern drainage from the site; the pond is elevated above the creek, and the creek itself is not
identified as a fishery (Ref. 53).

The nearest mapped downstream wetland in the western drainage pathway is on Irwin
Creek, 1.15 miles downstream from PPE 1; the next wetland interval is approximately 5 miles
downstream. The nearest wetland in the eastern drainage is on Dairy Branch, 0.2 mile
downstream from the PPE (Ref. 52).
SRR Surface Water Sampling and Results:
Part of the scope of the current SRR was to investigate whether cVOCs attributable to the
Parks-Cramer site had migrated to nearby surface water. Extensive groundwater contamination
had been documented at several Brownfields sites to the northwest of the Parks-Cramer site, but
the question remained as to whether contaminants had also migrated into the drainage to the east
of the site. The prediction was that groundwater contamination, if present, might be detected as
discharge to perennial surface water, and also in soil gas near surface water, where groundwater
elevation would be closer to the land surface than at locations closer to the site.
Surface water sampling was complicated by the presence of an extensive underground
storm drainage network in the site’s heavily urbanized setting. Sampling was originally planned
at PPE 1, the outfall in the northwest drainage; however, the owner of the vacant property
containing the PPE did not respond to a written access request. To the northeast of the property,
at the corner of West Boulevard and Worthington Street, a depression in the ground exposed the
junction of two storm drains: a storm drain along West Worthington Avenue linking to the
Brownfields properties northwest of the site, and a separate (background) drainage from the
north. However, despite recent precipitation, the junction was non-flowing when visually
examined during site visits on June 1 and June 13, 2022. As an alternative, a surface water
sample (PC02SW) was collected below PPE 1, accessed from a public park downstream from
Wilmore Drive (Ref. 54; Fig. 4A).
In the eastern drainage duplicate water samples (PC01SW; PC11SW) were collected at
PPE 2, located behind residences between East Tremont Avenue and Victorian Place (Ref. 54;
Fig. 4B).
SRR surface water samples were analyzed at the EPA Region 4 Laboratory for volatile
organic compounds. Results are summarized in Table 1 and Appendix B of this Report.
The water sample (PC02SW) taken below PPE 1 in the northwestern drainage contained TCE (1
µg/L), acetone (0.5 µg/L) and a trace of chloroform. The water samples (PC01SW and duplicate
PC11SW) collected at PPE 2 in the eastern drainage contained PCE (0.96 µg/L; 0.97 µg/L),
chloroform (1.4 µg/L; 1.2 µg/L) and trace levels of 1,1-dichloroethane and 1,1-dichloroethene.
The significance of these results will be discussed in the Subsurface Intrusion section of this
report. Based on the above information the exposure hazard posed via the surface water
migration pathway appears to be minimal.

Soil Exposure and Subsurface Intrusion and Air Pathways and Targets:
The Parks-Cramer site has been redeveloped for commercial and residential use under the
NC Brownfields program, with land use restrictions and mitigation measures against subsurface
intrusion of cVOC contamination that was previously documented in groundwater at the site.
Most of the redeveloped properties located in the downgradient (northwest) direction are also
NC Brownfields sites, with land use restrictions and/or vapor intrusion mitigation measures in
place. The scope of the current investigation was to use limited passive soil gas (PSG) sampling
to delineate the northwestward and eastward extent of contamination that could present a
potential Subsurface Intrusion (SsI) exposure hazard to non-commercial properties farther from
the site.
PSG sampling was conducted using a “Besure” passive soil-gas sampling kit, provided
by Beacon Environmental Services, Inc. PSG samplers were deployed on June 1, 2022 and
retrieved on June 13, 2022, after 12 days of equilibration. At each soil vapor sampling location,
a 1.5 inch-diameter hole was power-drilled into the ground surface to a depth of 1.0 foot. From
the bottom of the borehole, a 0.5 inch-diameter borehole was further advanced to a total depth of
3 feet. The PSG samplers were suspended by metal wire into the upper boreholes. Compacted
aluminum foil was used to anchor the upper sampler wires and to seal the upper boreholes from
the atmosphere. Following retrieval, samplers were secured and shipped to Beacon
Environmental for VOC analysis (Appendix B).
Beacon analyzed the PSG samples using EPA Method 8260C, for chlorinated and non-
chlorinated volatile organic compounds. A duplicate analysis (PC02SGDup) was performed on
downgradient PSG sampler PSG02SG (Appendix C). PSG sample results (micrograms/cubic
meter (µg/m3))are summarized in Table 1 and Appendix C of this report.
In the northwestern drainage pathway, PSG sampling (PC02SG and PC02SGDup;
PC03SG; PC04SG) was conducted at the former Palmers Automotive site (1900 South Tryon
Street – see above), the farthest downgradient Brownfields site with previously documented
cVOC contamination in groundwater and soil gas. Sampling was performed just inside the
western and northern property lines to evaluate the SsI potential at adjacent residential properties.
PCE was detected in two of the PSG samplers (PC03SG and PC04SG.
Concentrations (2.31 µg/m3; 10.2 µg/m3) were considerably lower than the (139 µg/m3) EPA
Vapor Intrusion Screening Level (VISL) Target Sub-slab/Near-Source concentration for
residential exposure. No TCE or other VOCs were detected in the three PSG samplers (Refs. 27,
54; Table 1; Appendix C).

Cumulative groundwater sample/elevation data from previous investigations indicate that
eastward transport of groundwater contaminants from the Parks-Cramer site is unlikely.
However, concurrent with surface water sampling at PPE 2 in the eastern drainage, the NC
Superfund Section conducted PSG sampling (PC01SG) at a residential property in proximity to
that location, where groundwater was anticipated to exist at minimal depth below ground surface.
The PSG sample contained toluene (7.4 µg/m3) and petroleum hydrocarbons (TPH 30,400
µg/m3) consistent with diesel fuel. Results were non-detect for cVOCs (Appendix C).
The NC Superfund Section evaluated the cVOC and toluene PSG sample results using
the EPA’s Vapor Intrusion Screening Level (VISL) Calculator. None of the results exceeded
Target Sub-slab/Near-source Soil Gas concentrations, based on a Residential Carcinogenic/Non-
carcinogenic Risk of 1.0E-6 and Hazard Quotient of 0.1 (Refs. 27, 55). Based on the above
sampling results, the off-site exposure hazard posed at the properties via the subsurface intrusion
component of the soil exposure and subsurface intrusion pathway appears to be minimal.
Comparison of PSG and Surface Water Sampling Results:
Northwestern Drainage: PCE was detected in soil gas at the downgradient property
lines at the former Palmers Automotive site, the farthest downgradient of the contiguous
Brownfields sites northwest of Parks-Cramer. TCE was not detected in soil gas at those locations.
Conversely, TCE was detected in surface water below PPE 1, where no PCE detection occurred.
In addition, PPE 1 is the likely surface discharge from multiple underground urban storm drains,
as evidenced by the fact that the PPE was discharging while a nearby visible storm drain junction
was not. Therefore, attribution of any surface water contaminant detection at the PPE to a
specific urban source would be difficult.
Eastern Drainage: The drainage outfall at PPE 2 discharges runoff from underground
storm drains that follow East Tremont Street, to the north of the PPE. PCE was detected in
surface water from PPE 2, but was not detected in a PSG sample from an upgradient residential
property on the southwest side of the stream. These results do not support groundwater
discharge from the site to the creek as a source for cVOCs.

[TOC_1]Case Narrative[TOC]Case Narrative
U.S. EPA Method 8260C
All samples were analyzed using thermal desorption-gas chromatography/mass spectrometry (TD-GC/MS)
instrumentation following U.S. EPA Method 8260C, with laboratory results provided in nanograms (ng) and
micrograms per cubic meter (!g/m‡). Laboratory QA/QC procedures included internal standards, surrogates, and
blanks based on EPA Method 8260C. Analyses and reporting were under BEACON’s Quality Assurance Project Plan.
Passive Soil-Gas Survey Notes
If sample locations are covered with or near the edge of an impervious surface (e.g., asphalt or concrete), the
concentrations of compounds in soil gas are higher than if the surfacing was not present. Therefore, the sample
location conditions should be considered when comparing results between locations.
Survey findings are exclusive to this project and when the spatial relationships are compared with results of other
BEACON Surveys it is necessary to incorporate information from both investigations (e.g., depth to sources, soil types,
porosity, soil moisture, presence of impervious surfacing, sample collection times).
Reporting Limits
The RLs represent a baseline above which results meet laboratory-determined limits of precision and accuracy. All
reported results are within the calibration range. The project method quantitation limit (MQL) is the limit of
quantitation (LOQ) as noted in the data tables. Beacon determined uptake rates for a suite of compounds with the
Beacon sampler for sampling in air. Beacon calculated the uptake rates for the remaining compounds using Grahams
Law of Diffusion. The reported data includes LOQ limits.
Project Details
Samples were received in proper condition and laboratory control parameters were met unless otherwise noted
below. The work performed was in accordance with ISO/IEC 17025:2017, except compounds reported with are
not included in Beacon’s scope of accreditation.

ACRONYMS AND ABBREVIATIONS
CAS Chemical Abstracts Service
Note: Analytes with no known CAS identifiers have been assigned codes beginning with "E", the EPA ID as assigned by
the EPA Substance Registry System (www.epa.gov/srs), or beginning with "R4-", a unique identifier assigned by the EPA
Region 4 laboratory.
MDL Method Detection Limit - The minimum concentration of a substance (an analyte) that can be measured and
reported with a 99% confidence that the analyte concentration is greater than zero.
MRL Minimum Reporting Limit - Analyte concentration that corresponds to the lowest demonstrated level of acceptable
quantitation. The MRL is sample-specific and accounts for preparation weights and volumes, dilutions, and
moisture content of soil/sediments.
TIC Tentatively Identified Compound - An analyte identified based on a match with the instrument software's mass
spectral library. A calibration standard has not been analyzed to confirm the compound's identification or the
estimated concentration reported.
