Subject: Preliminary Assessment (PA) Report
West Market Street Storage (a.k.a., Flav-o-Rich Dairy)
NCD 982 083 826
Greensboro, Guilford 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 Preliminary Assessment (PA) 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 private contractor’s site investigations
conducted at the site property in 2014 and 2015, under the NC DEQ Brownfields Program, prior
to Plat Recordation in 2016. NC and Guilford County geographic information system (GIS) data
were reviewed to identify potential groundwater receptors near the site. Field investigation
included off site residential passive soil gas (PSG) sampling, in order to supplement the previous
investigations and to protect public health.
Site Description, Operational and Regulatory History and Waste Characteristics:
Site Description:
The site is a commercial property located at 3939 West Market Street, Greensboro, NC
27407. The property lies between Market Street to the north and United Street to the south.
Geographic coordinates at the central part of the site property are 36.06806o N Latitude and
79.85293o West Longitude (Refs. 3, 4; Figs. 1, 2).
Ms. Bramble August 11, 2022,

The approximately 5.06-acre site property presently contains three permanent structures
and is operated as a commercial storage facility (Extra Space Storage), including a vehicle storage
garage, individual indoor cage storage units and company offices. Most of the outdoor portion of
the site is paved. The surrounding neighborhood has mixed commercial and residential use. To
the north of the site property are a preschool and an insurance company. To the east is an apartment
complex and beyond lie individual residential properties. The latter are also present to the south,
across United Street. To the west is a gasoline station/convenience store (Ref. 3).
Site elevation is approximately 870 feet above mean sea level and surface topography
generally slopes to the east-southeast. The nearest surface drainage is a tributary to North Buffalo
Creek, approximately 1200 feet to the south-southeast of the property (Ref. 3).
Site Operational and Regulatory History and Waste Characteristics:
The site property reportedly was used as a dairy company facility (various company names)
from at least 1948 until 2000. On the west side of the site property, the dairy facility’s main
structure and other structures were demolished, leaving two structures at the east end of the
property. In 2009, the former main structure was replaced by the current storage facility offices.
Prior to 2009, a second structure in the northeast portion of the property was used as an automotive
garage for maintenance of the dairy facility’s vehicle fleet (Ref. 3).
The dairy facility reportedly contained seven underground storage tanks, used for storage
of gasoline, diesel and heating oil. The fuel USTs were installed in 1964 and were removed
between 1991 and 2001. The two heating oil USTs and approximately 90 tons of impacted soil
were removed in December 2008, and the UST incident was deemed No Further Action by the
State of NC in 2010 (Ref. 3).
Flav-O-Rich, a dairy company that formerly operated on site, was listed as a historic
handler of spent non-halogenated solvents. According to the City of Greensboro Fire Department,
there were no recorded hazardous waste spills, responses or fires during site operation as a dairy
facility. County files indicated two ammonia spills, in 1995 and 1996, and an unknown chemical
spill in 1996 (Ref. 3).
In 2013, contractors for Extra Storage Space LLC conducted a Phase II Limited Subsurface
Investigation at the site, as part of due diligence for proposed acquisition of the property. The
investigation included completion of seven test borings and four temporary monitoring wells at
the site’s former UST area and in and around the northeast former vehicle maintenance building.
Sample analytical results included trichloroethene (TCE) at soil concentrations ranging up to 3
milligrams per kilogram (mg/kg) and at groundwater concentrations ranging up to 1,500
milligrams per liter (µg/L). The highest concentrations in both media occurred in samples
collected beneath the maintenance building. The second highest groundwater concentration (720
µg/L) occurred to the east-southeast of the maintenance building, near the property line and
adjacent apartment complex (Ref. 5).

In June 2014, at the request of the (then) NC DENR Brownfields Program, contractors for
Market Street Storage, LLC, the prospective site developer (PD), conducted a Phase II
Environmental Site Assessment at the site. Contractors installed six permanent monitoring wells
at outdoor locations within the eastern half of the site property. Groundwater sample analysis
detected tetrachloroethene (PCE) at 1.0 µg/L at one well location and TCE at 84 to 2,100 µg/L at
two well locations. The highest TCE result occurred to the east-southeast of the maintenance
building, near the property line and adjacent apartment complex. Cis-1,2-dichloroethene (DCE)
was also present at 180 µg/L at that location. Groundwater elevation data indicated migration to
the east-northeast (Ref. 3).
In February 2015, at the request of the NC DEQ Brownfields Program, contractors for the
PD conducted a Soil and Sub-Slab Vapor Assessment at the site property and at the apartment
complex to the east. Contractors installed soil vapor sampling points at the apartment complex,
approximately five feet from selected apartment buildings. Five soil vapor samples were collected
at 10 feet depth, and two of the sampling locations were additionally sampled at 15 feet depth.
One sub-slab soil vapor sample, collected beneath the maintenance building on the site property,
was non-detect for VOCs (Ref. 6).
TCE was detected in four of the five 10-foot soil gas samples at concentrations of 9.2 to
5,300 µg/m3, and in one of the two 15-foot samples at 13,000 µg/m3. The highest TCE
concentrations occurred at a location directly across the property line from the site property’s
maintenance building. All of the TCE detections exceeded the EPA’s Target Sub-slab/Near Source
Residential Vapor Intrusion Screening Level (VISLs) of 6.95 µg/m3 (Refs 6, 7).
PCE was detected in all of the February 2015 soil vapor samples at concentrations ranging
from 8.3 to 430 µg/m3. The highest PCE concentrations occurred to the east and south of the
maintenance building. Four of the PCE detections exceeded the EPA Target Sub-slab/Near Source
Residential VISL of 139 µg/m3 (Refs 6, 7).
In May 2015, at the request of the NC DEQ Brownfields Program, contractors for the PD
conducted an Indoor Air Assessment at apartment buildings located directly east of the site
property. Contractors installed passive diffusion vapor samplers (7-day deployment) inside the
eight ground-level apartments in Buildings 4250 and 4252, located in proximity to the highest
prior TCE and PCE soil vapor sampling results (Ref. 8).
TCE detections inside two apartment units in Building 4250 exceeded the EPA’s health-
based carcinogenic indoor air benchmark of 0.478 µg/m3 (Ref. 2). TCE was detected in four
additional units at much lower concentrations (0.031 to 0.071 µg/m3) which did not exceed the
benchmark. PCE was detected in all eight units at concentrations less than its (10.8 µg/m3)
carcinogenic benchmark. The two highest TCE concentrations and one of the eight PCE
concentrations also exceeded their EPA Target Residential Indoor Air VISLs of 0.209 µg/m3 and
4.17 µg/m3, respectively (Refs. 7, 8).

During Summer of 2015 PD contractors installed temporary portable carbon air filtration
units inside the two TCE-contaminated apartments in Building 4250. In February 2016 contractors
removed the air filters and installed a fan-driven sub-slab depressurization system in the building,
with extraction points in each of the building’s four ground-level apartments. Post-installation
indoor air sampling in March and May 2016 confirmed that PCE and TCE concentrations in the
four apartment units had been reduced below laboratory detection limits (Ref. 9).
In February 2016, state contractors for the NC DEQ Superfund Section Inactive Hazardous
Sites Branch (IHSB) conducted follow-up outdoor soil vapor sampling at the apartment complex
east of the site property. Using push-rod technology, contractors installed nine soil vapor sampling
points (to 10-foot depth) adjacent to six of the eight complex buildings. TCE and/or PCE were
detected in Summa Canister samples from two of the sampling locations, in relative proximity to
the site property; the other seven samples, taken at greater downgradient distance from the property
line, were all non-detect. The single TCE detection that occurred (27.7 µg/m3) was the only result
to exceed its Target Sub-slab/Near Source Residential VISL of 6.95 µg/m3 (Refs. 7, 10).
Groundwater Migration Pathway and Targets:
Guilford County, NC lies within the Piedmont Physiographic Province, and the site
location is within the northwestern portion of the Carolina Slate Geotectonic Belt. Bedrock
geology in the site vicinity is mapped as consisting of a metamorphosed complex of felsic intrusive
igneous rock to the southeast, bordered by a large area of intermediate intrusive igneous rock to
the northwest (Refs. 11, 12).
Soil beneath the site property is mapped as Urban Land, where the natural soil profile has
been disturbed by cutting, filling, grading or paving. Historical subsurface explorations at the site
have encountered approximately 15 to 25 feet of silty clayey soil overlying the saprolite (weathered
bedrock) interface. Within the Piedmont, the unconfined groundwater aquifer comprises the
saturated zone of fractured bedrock and the overlying weathered saprolite (Refs. 3, 11, 13, 14).
Historical groundwater investigation at the site indicated depths to groundwater ranging
from approximately 21 to 26 feet below ground surface. Based on surface topography alone,
groundwater beneath the site would be anticipated to migrate to the east-southeast. However,
groundwater elevation data indicate an initial northeasterly component (Refs. 3, 14).

The site is located within the Greensboro municipal boundary and local residences and
businesses have access to municipal water and wastewater service. The municipal water source
consists of surface water intakes on Lake Higgins, Lake Brandt and Lake Townsend in northern
Guilford County. The nearest public/community groundwater source is located more than 4 miles
from the site (Refs. 15, 16; Fig. 1). Based on the absence of proximal groundwater targets, the
exposure hazard posed by the site’s groundwater migration pathway appears to be minimal.
Surface Water Migration Pathway and Targets:
The site property lies within the North Buffalo Creek drainage basin. The overland
drainage pathway surface slope runs southeast from the site property line for approximately 1500
feet, crossing Rosebriar Court and continuing to West Wendover Avenue (Ref. 13). North Buffalo
Creek flows east-northeast parallel to West Wendover Avenue, and the probable point of entry
(PPE) for overland flow and groundwater discharge is located on the south side of West Wendover
Avenue between United Street and Holden Avenue. North Buffalo Creek continues northeast,
constituting the entire 15-mile surface water migration pathway target distance limit (TDL) (Refs.
4, 13; See Figures 1 and 2).
No public surface-water intakes reportedly operate within the 15-mile TDL (Ref. 15; Fig.
1). The North Carolina Wildlife Resources Commission does not identify any recreational
fishing sites along North Buffalo Creek (Ref. 18). In addition, due to the urban setting, the upper
portions of North Buffalo Creek are unlikely to sustain fish populations suitable for human
consumption. The nearest mapped wetland is located approximately 9.1 miles downstream from
the PPE (Ref. 17). Based on the above information, the exposure hazard posed by the site’s surface
water migration pathway appears to be minimal.
Soil Exposure and Subsurface Intrusion and Air Migration Pathways:
The site is located in a mixed commercial and residential urban setting. Most of the site
property is paved or covered by structures, limiting the likelihood of direct exposure to any
contaminated soils other than during subsurface construction/excavation. One day care facility is
located approximately 150 feet northwest of the apparent on-site contaminant source area. Areas
to the south and southeast contain residences and apartments, respectively (Refs. 4, 10, 13) (also
see Figure. 2).
The site has been re-developed into a self-storage facility with oversight by the NC DEQ
Brownfields program. Investigations by the PD determined that groundwater contamination
originated beneath an on-site maintenance garage and migrated eastward beneath the adjacent
apartment complex, resulting in subsurface intrusion of chlorinated volatile organic compounds
(cVOCs) into proximal ground floor apartment units (Refs 5, 6, 8, 9, 10, 14).

In February 2016, the PD installed sub-slab depressurization vapor intrusion mitigation
systems (VIMS) at two affected units where TCE concentrations exceeded EPA benchmarks.
Follow-up soil gas and indoor air investigations determined that the VIMS was functioning as
designed, and that subsurface intrusion potential within the apartment property was limited to a far
western portion of the apartment complex property in proximity to the source (Refs 5, 6, 8, 9, 10,
14).
The purpose of the current PA was to determine whether additional subsurface intrusion
potential existed topographically downgradient from the site vicinity, in areas where eastward
migrating groundwater might be encountered closer to the ground surface than at the site and
adjacent apartments. Investigation focused on residential and commercial propert ies within a
drainage swale trending southeastward from the site vicinity toward the intersections of United
Street, South Holden Road and Ashland Drive. The scope of the PA consisted of passive soil gas
sampling along Rosebriar Court, a cul-de-sac crossing the drainage feature. Two additional PSG
sampling locations were accessed along United Street, farther downgradient within the feature
(Refs. 13, 19) (also see Figure 2).
PSG sampling was conducted using a “Besure” passive soil-gas sampling kit, provided by
Beacon Environmental Services, Inc. PSG samplers were emplaced at six locations within the
drainage feature. PSG samplers MS01SG through MS04SG were emplaced directly downgradient
from four residences on opposite sides of Rosebriar Court, straddling the axis of the drainage.
Samplers MS05SG and MS06SG were emplaced farther southeast, at one residential and one
commercial property located between United Street, South Holden Road and Ashland Drive (Ref.
19) (see also Figure 2 and Appendix A).
PSG samplers were deployed on May 19, 2022 and retrieved on June 2, 2022, after 14 days
of equilibration (Ref. 9). 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 (MS06SGDup) was performed on
downgradient PSG sampler MS06SG (Appendix B).

PSG sample results are summarized in Appendix B of this report. PSG sampler MS02SG,
located downgradient of one of the four residences on Rosebriar Court, contained toluene
(calculated concentration: 4.05 µg/m3). Duplicate analyses of PSG sampler MS06SG, located on
a commercial property farther downgradient from the site, detected benzene (calculated
concentrations: 2.44 µg/m3 and 2.50 µg/m3). Neither the benzene nor the toluene concentrations
exceeded their respective Target Sub-slab/Near Source Residential VISLs of 12 µg/m3 and 17,400
µg/m3. No other VOC detections occurred in any of the PSG samplers. PSG sampler MS05SG was
found to have been removed from its borehole and therefore was not analyzed. Survey flagging
marking the sample location was undisturbed; therefore, animal activity was suspected. (Refs. 7,
19; Appendix B).
The NC Superfund Section evaluated the above PSG sample results using the EPA’s Vapor
Intrusion Screening Level (VISL) Calculator. Neither the benzene nor the toluene concentrations
exceeded their respective Target Sub-slab/Near Source Residential VISLs of 12 µg/m3 and 17,400
µg/m3, based on a Carcinogenic/Non-carcinogenic Risk of 1.0E-6 and Hazard Quotient of 0.1 (Ref.
7). Based on the above sampling results, the off-site exposure hazard posed via the subsurface
intrusion component of the soil exposure and subsurface intrusion and air migration pathways
appears to be minimal.
Preliminary Assessment Conclusions:
The primary purpose of the PA was to address the subsurface (vapor) intrusion exposure
pathway, for which cVOCs were the contaminant of concern at this site. Results of historical
investigations of the adjacent property and current PSG sampling results from downgradient
properties indicate that a minimal off-site exposure hazard exists as a result of historic site
activities.
Based on current site conditions, the West Market Street Storage site is recommended for
No Further Remedial Action Planned (NFRAP) designation under CERCLA. If you have any
questions, please contact me at [e-mail] or [phone].

[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.
