BROWNFIELDS ASSESSMENT REPORT
TAYLOR SALT AND CHEMICAL BROWNFIELDS SITE
NCBP #21004-17-060
3915 GLENWOOD DRIVE
CHARLOTTE, NORTH CAROLINA
Terracon Project No. 71177602
October 10, 2018
1.0 SITE DESCRIPTION
1.1 General Site Description
The Taylor Salt and Chemical Brownfields project site is located at 3915 Glenwood Drive in
Charlotte, North Carolina. The site consists of an approximate 3.75-acre parcel improved with
several adjoining commercial/industrial warehouse buildings, totaling 51,615 square feet.
Currently, the buildings are occupied by multiple tenants. Exterior portions of the site consist
mostly of asphalt -paved vehicle access and parking areas with limited landscaped areas. The
property is identified in Mecklenburg County tax records as Parcel No. 06506147. The site was
accepted into the North Carolina Brownfields Program in May 2017 with J-J-C Real Estate
Investments, LLC identified as the prospective developer (PD). The site location is shown on
Figure 1.
Surrounding land use consists of industrial/commercial properties to the north and northeast. A
daycare center is located directly south of the site. Single-family residences are located to the
west of the site and the eastern adjoining property is currently undeveloped. The site is
relatively level but the topographic gradient slopes slightly downward to the southeast towards a
tributary of Stewart Creek. Groundwater at the site is between 20 and 25 feet below ground
surface (bgs) based on sampling activities.
1.2 Site History
Terracon performed a review of multiple historical and regulatory documents available for the
site and surrounding properties including groundwater monitoring reports, site assessment
reports and a plume investigation report as part of the completion of a Phase I Environmental
Site Assessment (ESA) in 2016. Terracon also reviewed a Preliminary Fate and Transport
Model Memorandum prepared by AECOM (Included in Appendix A). The site's assessment
history is summarized below.
Reportedly, the site was occupied by Taylor Salt and Chemical from at least 1960 until 1978
when Taylor Salt was apparently acquired by Prillaman Chemical Corporation. Taylor Salt and
Chemical continued to operate on the site as a Division of Prillaman Chemical Corporation until
the late 1990s. The site was subsequently occupied by Univar USA, Inc. (Univar) in the early

2000s. Since 2003, the site has been occupied as a multi -tenant facility named Glenwood
Business Park. Historical locations of on -site operations are depicted on Figure 2.
Taylor Salt and Chemical distributed and repackaged salts, acids, solvents, and caustics. Bulk
amounts of ammonia, acetic acid, sulfuric acid, caustic soda, isopropanol, mineral spirits, methyl
ethyl ketone, and methanol were stored on the site as part of on -site operations. A railroad spur
located along the northern property boundary (Figure 2) was used as a receiving area for raw
bulk materials. The bulk materials were stored in various aboveground storage tanks (ASTs)
located near the railroad spur and the bulk products were drummed in the covered area located
south of the ASTs. According to historical documents, a reported release of "salt and other
chemicals" occurred during unloading of chemicals along the railway spur in 1977. No other
information was provided in the regulatory files regarding the release.
In 1995, a 10,000-gallon diesel UST was removed from the south-central portion of the site near
the flammables storage building (Figure 2). Approximately 450 tons of petroleum impacted soil
were removed from the tank basin. The NCDEQ identified the release as Incident No. 13641.
Confirmation samples collected from the tank basin after over -excavation did not identify
residual contamination and in March 1995, the NCDEQ issued a No Further Action (NFA) letter
for the release. A new 10,000-gallon diesel UST was reportedly installed in the former tank
basin in 1995. In August 1997, eight soil samples and four groundwater samples were collected
near the new diesel UST. Analytical results identified petroleum constituents above their
respective standards in the soil and groundwater samples. Based on the sample results, the
new tank was removed in 1998. During removal of the 10,000-gallon UST, petroleum impacted
soils were identified and approximately 130 cubic yards of impacted soil were removed from the
site. The NCDEQ identified the new release as Incident No. 19511. Currently, Incident No.
19511 remains open as a Leaking Underground Storage Tank (LUST) incident.
In March 1998, Advent conducted a soil, groundwater and soil gas assessment of the property
to evaluate historical operations on the site and potential impacts from neighboring up -gradient
facilities. Advent collected nine soil samples, nine groundwater samples, and 33 soil gas
samples at the site to determine the magnitude of contamination. Multiple soil samples detected
residual petroleum contamination near the former diesel UST in the southern portion of the site
and chlorinated compounds in areas of past bulk chemical storage areas. Multiple volatile
organic compounds (VOCs) were detected in the groundwater above their respective 2L
Groundwater Quality Standards. Advent concluded on -site sources and off -site sources of
contamination contributed to the groundwater impacts at the site. Benzene, 1, 1 -dichloroethene,
trichloroethene (TCE), toluene, xylenes, and tetrachloroethene (PCE) were detected in various
soil gas samples.
Annual groundwater monitoring events have been conducted on the site since 1998.
Chlorinated constituents have been detected in the on -site wells above 2L standards since the
initial assessment in 1998 by Advent. It is Terracon's understanding that Univar USA, Inc. has
Responsive ■ Resourceful ■ Reliable 2

Brownfields Assessment Report Irerracon
Taylor Salt and Chemical Charlotte, NC
October 10, 2018 Terracon Project No. 71177602
been and is currently conducting voluntary remedial actions at the site to address the
chlorinated compounds. In October 2004, Bascor Environmental, Inc. (Bascor) on behalf of
Univar conducted a soil vapor extraction (SVE) pilot test at the site to evaluate the effectiveness
of the remedial technology and provide design parameters for a permanent SVE system. Bascor
installed and initiated startup of a permanent SVE system at the site in March 2009. The SVE
system is divided into two "legs". Leg 1 includes vapor extraction wells located directly south of
the on -site building and Leg 2 extends along the southern extent of the site. Soil gas results
from a sampling event conducted in September 2014 by AECOM identified PCE above its
Residential or Non -Residential Soil Gas Screening Level (SGSL) at multiple locations on the
site. In November 2014, AECOM collected 15 indoor air samples within the on -site buildings.
Although PCE was detected in nine of the 15 samples, the concentrations were an order of
magnitude below the Residential Indoor Air Screening Level. Other VOCs were not detected
above the laboratory's method detection limits. According to the 2014-2015 Annual Monitoring
Report, dated June 2016, Leg 1 has been discontinued and only Leg 2 is in operation.
Off -Site Environmental Concerns
The former Boggs and Company facility, located on the adjacent, up -gradient property to the
north of the site operated as a dry-cleaning equipment and chemical supply company from at
least 1941 until the 1990s. In 1972 and 1984, an unknown amount of PCE was released from
an aboveground storage tank (AST) at the Boggs and Company facility. Based on a 2017
Preliminary Fate and Transport Model Memorandum completed by AECOM, the extent of the
contamination has been traced from the Boggs and Company facility onto the Taylor Salt and
Chemical site as well as other adjoining down -gradient properties to the southwest. The Bogg
and Company site is included in the NC Dry -Cleaning Solvent Cleanup Act (DSCA) Program
and is identified as DSCA facility No. 60-0010.
2.0 SCOPE OF SERVICES
Terracon conducted the Brownfields Assessment activities in general accordance with the
Brownfields Assessment Work Plan, dated July 11, 2018, approved by the NC Brownfields

3.0 FIELD INVESTIGATION METHODS
Terracon conducted the field work in accordance with a health and safety plan developed for
this project. Work was performed using United States Environmental Protection Agency
(USEPA) Level D work attire consisting of hard hats, safety glasses, protective gloves, and
protective boots.
3.1 Groundwater Sampling
Terracon collected groundwater samples from three existing on -site monitoring wells (MW-4A,
MW-10A and MW-15) on August 19, 2018. Prior to sample collection, Terracon gauged the
groundwater elevations in the monitoring wells using a clean electronic water level indicator.
Terracon collected an additional groundwater level measurement from monitoring well MW-14A
on September 18, 2018 to determine groundwater flow direction on the site. Groundwater
elevation measurements and monitoring well construction information are provided in Table 3.
The locations of the monitoring wells are located on Figures 3 and 4. The wells were purged
using a peristaltic pump and low -flow sampling methods until field parameters of temperature,
pH, oxidation-reduction potential, specific conductance, dissolved oxygen had stabilized.
Groundwater sample collection records are provided in Appendix A. Purge water was
contained in 5-gallon buckets and disposed by Concord Industrial Service Company (CISCO). A
copy of the disposal manifest is included in Appendix A.
The three groundwater samples and one duplicate sample (DUP-01-20180819) were placed in
laboratory -supplied glassware, labeled and stored in an ice -packed cooler. The samples, along
with chain -of -custody documentation, were delivered to Pace Analytical Services, Inc. in
Huntersville, North Carolina for analysis of VOCs by EPA Method 8260, semi -volatile organic

compounds (SVOCs) by EPA Method 8270, and RCRA metals by EPA Methods 6020 and
7470.
3.2 Soil Sampling
Prior to intrusive activities, Terracon submitted a locate request to the public utility locator [NC
811] to arrange for location of underground public utilities from the street to the utility meter at
the site. The soil sample locations are shown on Figure 3.
On August 19, 2018, Terracon mobilized to the site to collect two soil samples (HA-01 and HA-
02) and one background sample (BG-01). The two soil borings were advanced to a depth of 5
feet using a clean, decontaminated hand -auger. Soil boring/sampling activities were conducted
within the unsaturated zone only. Soil type, relative moisture content, and other lithologic
characteristics were documented in the field on boring logs (Appendix A). Soils consisted
predominantly of red and brown/grey sandy silt and clayey silt with moderate to low moisture.
Photo -ionization detector (PID) readings did not indicate VOC impacts in recovered soils.
Terracon collected a sample from the 4 to 5-foot depth interval for borings HA-01 and HA-02. A
composite sample was obtained from the 0 to 2-foot depth interval for sample BG-01. The
boreholes were abandoned using soil cuttings after the sampling activities were completed.
The three soil samples and one duplicate samples (DUP-02-20180819) were placed in
laboratory -prepared glass containers, labeled with pertinent sample information and stored in an
ice -packed cooler pending submittal to a North Carolina certified laboratory for analysis.
Samples HA-01, HA-02 and the duplicate sample were analyzed for of VOCs by EPA Method
8260, SVOCs by EPA Method 8270 and the eight RCRA metals by EPA Method 6010 in
accordance with requirements by the North Carolina Brownfields Program. Sample BG-01 was
only analyzed for the eight RCRA metals by EPA Method 6010 in accordance with the DEQ-
approved Work Plan. Chain of custody documentation accompanied the samples to the
laboratory.
3.3 Indoor / Outdoor Air Sampling
Terracon also collected five indoor air samples and one outdoor air sample at the site on August
19, 2018. Indoor and outdoor air sample locations are shown on Figure 3.
Terracon collected indoor air (IA) and outdoor air (OA) samples from the following locations at
the site:
IA-01 — Office/Warehouse Building

The six air samples and one duplicate sample (Dup20181908) were collected in laboratory
supplied 6-liter Summa° canisters attached to a flow controller set for approximately 8 hours.
Following completion of the field activities, the seven Summa° canisters, along with chain -of -
custody documentation, were shipped to Con -test Analytical Laboratory in East Longmeadow,
MA for analysis of VOCs by modified EPA Method TO-15 Low Level.
Terracon recorded the remaining vacuum pressure inside each of the Summa° canisters at
regular intervals throughout the sampling period. Field sample collection records for indoor and
outdoor air are provided in Appendix A.
3.4 Brownfields Receptor Survey
Terracon completed a Brownfields Receptor Survey form provided by the NC Brownfields
Program as part of the assessment activities for the site. The Brownfields Receptor Survey form
was completed during our field observations and research portion of the receptor survey.
Terracon did not identify private or public water supply wells or private irrigation wells within
1,500 feet of the site. According to the National Wetlands Inventory, a tributary of Stewart Creek
is located approximately 575 feet south of the site. The completed form is included in Appendix
A.
4.0 RESULTS
The laboratory analytical reports and chain -of -custody records are attached in Appendix B. The
following sections describe the sample results.
4.1 Site Hydrogeology
Groundwater levels measured in four on -site monitoring wells ranged from 20.12 feet below
ground surface (bgs) in well MW-4A to 25.23 feet bgs in well MW-15 on August 19, 2018 and
September 18, 2018. Groundwater elevations were calculated using field measurements and
the top of casing and ground elevation data from the AECOM 2014-2015 Annual Monitoring
Report dated June 2016. Groundwater depths and elevations are reported in Table 3. A
groundwater elevation contour map is provided as Figure 4.
Groundwater on the site appears to be flowing to the south/southeast towards an unnamed
tributary of Stewart Creek. According to the 2014-2015 Annual Monitoring Report (AECOM),
dated June 2016 and groundwater measurements collected in August and September 2018, the

average horizontal groundwater gradient is 0.02 feet/foot from the northern to southern portions
of the site.
4.2 Groundwater Sample Results
On August 19, 2018, groundwater samples were collected from on -site monitoring wells MW-
4A, MW-10A and MW-15. Laboratory analytical results for VOCs, SVOCs and RCRA metals are
discussed separately below. Groundwater analytical results are summarized in Table 4 and
shown on Figure 6. The laboratory analytical reports are included in Appendix B. Groundwater
sample results were compared to the North Carolina Administrative Code Subchapter 2L
Groundwater Quality Standards, effective April 1, 2013.
VOCs
Tetrachloroethene (PCE) was detected in each of the groundwater samples above its NCAC
15A 2L groundwater quality standard of 0.7 micrograms per liter (pg/L). Trichloroethene (TCE)
was detected in samples MW-4A (34.1 pg/L) and MW-15 (6.6 lag/L) above its 2L standard of 3
pg/L. Vinyl chloride (18.5 pg/L) and cis-1,2-dichloroethene (83.5 pg/L) were detected in well
MW-4A above their respective 2L standards. Various other VOCs were detected in the three
samples at concentrations above the laboratory reporting limits but below their respective 2L
standards.
1,4-Dichlorobenzene was detected in samples MW-4A and MW-15 with a "J-Flag" qualifier. The
"J-Flag" qualifier indicates the reported value is above the laboratory method detection limit but
below the laboratory reporting limit. No SVOCs were detected above laboratory reporting limits
or their respective 2L standards.
RCRA Metals
The following RCRA metals were detected in the groundwater at the site.
Arsenic, barium, chromium and lead were detected in samples MW-4A, MW-10A, MW-
15 and DUP-01-20180819 above laboratory reporting limits but below their respective 2L
standards.
Cadmium was detected in sample MW-4A, MW-10A and DUP-01-20180819 above its
laboratory reporting limit but below the 2L standard of 2 pg/L.
Selenium was detected in samples MW-10A and DUP-01-20180819 at concentrations
above the laboratory method detection limit but below the laboratory reporting limit and
its 2L standard.
Silver was detected in samples MW-4A, MW-10A and DUP-01-20180819 above the
laboratory method detection limit but below the laboratory reporting limit and its 2L
standard.

In addition to comparing the analytical results with the 2L standards, Terracon also used the
Brownfields Vapor Intrusion Groundwater Concentration to Indoor Air Concentration (GWC-IAC)
Calculator (February 2018 Version) to assess the potential vapor intrusion risk from off -gassing
of impacted groundwater. Under a residential scenario, the cumulative carcinogenic risk and the
non -carcinogenic hazard quotient for sample MW-4A exceed the acceptable threshold values.
According to the calculator, the non -carcinogenic hazard quotient also exceeds the acceptable
threshold value for sample MW-15 under a residential scenario. The cumulative carcinogenic
risk and the non -carcinogenic hazard quotient for samples MW-10A and DUP-01-20180819 are
below the threshold values under a residential scenario.
Under a non-residential scenario, the non -carcinogenic hazard quotient for sample MW-4A
exceeds the acceptable threshold value. The cumulative carcinogenic risk and non -carcinogenic
hazard quotient are below the acceptable threshold values for samples MW-10A, MW-15 and
DUP-01-20180819 for a non-residential scenario. The residential and non-residential risk
calculator summary sheets for samples MW-4A, MW-10A, MW-15 and DUP-01-20180819 are
included in Appendix C.
4.3 Soil Sample Results
Two soil samples were collected for laboratory analysis in the northern portion of the site along
the railroad spur near a reported release of salt and other chemicals in 1977. Laboratory results
are summarized below and in Table 2 and are also shown on Figure 5. The laboratory
analytical reports are included in Appendix B. Detected concentrations were compared to the
IHSB Residential and Non -Residential Preliminary Soil Remediation Goals (PSRGs), February
2018 version. Concentrations were also evaluated using the Brownfields Soil Risk Calculators.
VOCs and SVOCs
Methylene chloride was detected in the duplicate soil sample (DUP-02-20180819) with a "J-
Flag" qualifier and at a concentration below the Residential PSRG. VOCs were not detected
above the laboratory reporting limits or the PSRGs in the remaining two soil samples.
SVOCs were not detected above laboratory reporting limits or the PSRGs in the samples
collected in the northern portion of the site (HA-01, HA-02 and DUP-02-20180819).
RCRA Metals
The following RCRA Metals were detected above laboratory reporting limits in the soils at the
site.
Arsenic was the only metal detected above its Residential or Non -Residential PSRGs
with concentrations ranging from 1.6 to 8 milligrams per kilogram (mg/kg). Arsenic
detected in samples HA-01 and DUP-02-20180819 exceeded the Non -Residential
Responsive ■ Resourceful ■ Reliable 8

PSRG while concentrations detected in samples HA-02 and BG-01 exceeded the
Residential PSRG. The concentrations of arsenic detected in the August 2018 soil
samples are generally within published naturally occurring metal concentrations for the
site area (Geochemical Landscapes of the Conterminous United States — New Map
Presentations for 22 Elements, USGS, 2001).
Barium, cadmium, chromium, lead, mercury and silver were also detected in one or
more soil samples at concentrations below their respective Residential PSRGs.
Detected concentrations in the soil samples were evaluated using the NC Brownfields Program
Soil Risk Calculator. Under a residential and a non-residential scenario, the cumulative
calculated carcinogenic risk and non -carcinogenic hazard quotient are below the acceptable
threshold values. The residential and non-residential risk calculator summary sheets for each of
the soil samples are included in Appendix C.
4.4 Indoor and Outdoor Air Sample Results
Indoor and outdoor air sample results are shown on Figure 7 and summarized on Table 5. The
laboratory analytical reports are included in Appendix B. Sample results for the six indoor air
samples (including the duplicate) and the one outdoor air sample collected at the site were
compared to the NCDEQ DWM Indoor Air and Crawlspace Screening Concentrations (IASLs)
for a residential and a non-residential exposure scenario, updated February 2018. Specifically,
the more conservative IASL (A) with a target carcinogenic risk of 1.0E-6 and a target hazard
quotient of 0.2 was used for the comparative evaluation.
In addition to the IASLs, Terracon also evaluated the indoor and outdoor sample results using
the INC Brownfields Program Indoor Air Concentration to Risk (IAC-Risk) Calculator, February
2018 Version. The risk calculators are included in Appendix C. Below is a summary of
laboratory analytical results and risk evaluation results.
Tetrachloroethylene was detected in sample IA-04 (180 pg/m3) above the non-residential
IASL of 35 micrograms per cubic meter (pg/m3).
1,2-Dichloroethane was detected in samples IA-01 (1.1 pg/m3) and IA-03 (0.93 pg/m3)
above the non-residential IASL of 0.47 pg/m3. 1,2-Dichloroethane was also detected in
sample IA-04 above the residential IASL of 0.11 pg/m3.
Naphthalene was detected in each of the indoor air samples above the non-residential
IASL, including the duplicate sample.
Benzene was detected in samples IA-01, IA-02, IA-03, IA-04, IA-05 and DUP20181908
above its residential IASL.
Carbon tetrachloride and ethylbenzene were detected in samples IA-01 and IA-04 at
concentrations above their respective residential IASLs.
Chloroform was detected in indoor air samples IA-01 through IA-04 and DUP20181908
at concentrations above its residential IASL.

1,4-Dichlorobenzene was detected in sample IA-03 above its residential IASL.
The outdoor air sample contained naphthalene (0.19 pg/m3) above the residential IASL
of 0.083 pg/m3. The source of naphthalene is unknown but is likely related to vehicular
traffic or commercial activities on the site or on the nearby road.
Under a residential exposure scenario, samples IA-01, IA-03 and IA-04 exceed the acceptable
non -carcinogenic hazard quotient threshold value. Under a non-residential exposure scenario,
sample IA-04 exceeds the acceptable cumulative non -carcinogenic hazard quotient threshold
value. Under residential and non-residential scenarios, the cumulative vapor intrusion
carcinogenic risk and hazard quotient are below the acceptable threshold values for samples IA-
02, IA-05 and OA-02.
5.0 CONCLUSIONS AND RECOMMENDATIONS
Based on the scope of services described in this report and subject to the limitations described
herein, Terracon provides the following conclusions.
Soil
Methylene chloride was detected in one of the soil samples above laboratory reporting
limits but below the Residential PSRG. VOCs were not detected in the other two soil
samples above laboratory reporting limits.
SVOCs were not detected above laboratory reporting limits in the two samples collected
in the northern portion of the site.
Although arsenic was detected in each sample above its Residential or Non -Residential
PSRG, the detected concentrations are believed to be naturally occurring and are
consistent with the range of published naturally occurring metals concentrations for the
site area.
Other metals were detected in the soil samples at concentrations below their respective
Residential PSRGs.
According to the Brownfields soil risk calculator, cumulative carcinogenic risk and the
target hazard quotient for non -carcinogens are below the acceptable threshold limits for
the soil samples under a residential and non-residential scenario.
No additional soil assessment is recommended at this time.
Groundwater
Depth to groundwater at the site ranged between 20.12 and 25.23 feet bgs and the
groundwater flow direction is generally towards the south-southeast.
PCE was detected in each sample above its 2L standard. TCE was detected in two
samples above its 2L standard and vinyl chloride and cis- 1,2-dichloroethene were

Brownfields Assessment Report Irerracon
Taylor Salt and Chemical Charlotte, NC
October 10, 2018 Terracon Project No. 71177602
Detected SVOCs and metals were at concentrations below their respective 2L
standards.
The Brownfields GWC-IAC Calculator confirms that under a residential and non-
residential use scenario, off -gassing from groundwater at the site represents a potential
vapor intrusion concern near well MW-4A.
Groundwater will not be used for any purpose at the site and is not anticipated to be
encountered during redevelopment activities.
The 2017 Preliminary Fate and Transport Model Memorandum collected by AECOM
indicates that the upgradient Boggs and Company site is the likely source of the
groundwater impacts on the subject site.
Indoor and Outdoor Air
VOCs were detected in the six indoor air samples above their residential or non-
residential IASLs.
Naphthalene was detected in each of the indoor air samples above its non-residential
IASL.
PCE was detected in indoor air sample IA-04, collected in the former chemical storage
warehouse, above its non-residential IASL. PCE has historically been detected in the
soil gas samples collected elsewhere on the site.
Cumulative risk evaluations using the Brownfields Program IAC-Risk Calculator confirm
vapor intrusion risks for the six indoor air samples collected at the site are above the
acceptable threshold values under a residential exposure scenario for samples IA-01,
IA-03 and IA-04. The calculated non -carcinogenic hazard quotient also exceeds the
acceptable threshold value for sample IA-04 under a non-residential scenario.
Naphthalene was detected in the outdoor air sample above its residential IASL;
however, the Brownfields IAC-Risk Calculator confirms acceptable risk.
The 2017 Preliminary Fate and Transport Model Memorandum completed by AECOM
indicates that the upgradient Boggs and Company site is the likely source of the VOC
impacts on the subject site.
Terracon recommends contacting the DSCA Program so it can address any further
vapor assessment or mitigation at the subject site.

Fate and Transport Model
Project ref:
60478479
From:
Robbi McKinney
Date:
June 1, 2017
The Former Univar USA Inc. (Univar) Glenwood Drive facility (Site), located at 3915 Glenwood Dive has been undergoing
active assessment and remediation since 1997 when Ellis and Everard (US Holdings) Inc. initiated an investigation in support
of acquisition of two properties of the Taylor Salt & Chemical Company (Taylor Salt). The Taylor Salt facility historically
operated as a chemical distribution plant. Its primary business was distribution of acids, caustics, and salts, and contained
aboveground storage tanks utilized for non -halogenated solvents such as isopropanol, methyl ethyl ketone, and methanol
[Bascor Environmental Inc., (BEI) 2010]. Available Site records indicate minimal use or storage of tetrachloroethene (PCE),
the main COC on Site. Employee interviews conducted by Advent Environmental, Inc., and documented in their 1997
Summary of Environmental Site Assessment report, indicated that PCE and trichloroethene (TCE) were drummed in a
parking area just west of the current employee parking area (Figure 1). In 1997, soil gas samples were collected throughout
the area to the west of the employee parking lot in an attempt to identify potential source areas (Advent 1997). Locations
possessing the highest soil gas readings were then sampled using Geoprobe technology. The highest on site soil gas
reading was located at SG-22. The corresponding Geoprobe location was named DPT-22 and is shown on Figure 1. This
location is believed to correspond with the highest observed Site soil PCE concentration. This potential soil "source" location
is approximately 150 feet down gradient of the highest groundwater PCE concentrations on site, observed in MW-4A (Figure
1). It should be noted that BEI identified an area in the 2005-2009 Site Assessment Activities Report referred to as a
"Possible Former Solvent Repackaging Area" (shown on Figure 1 for reference) located between MW-8I and the Chemical
Storage Building (2010). However, there is no record that BEI investigated this area further than the original 1997 Advent
Environmental Site Assessment report. Further, the 1997 Advent soil gas data for samples collected in the "Possible Former
Solvent Repackaging Area" identified by BEI was reported at concentrations below laboratory method detection limits (MDLs)
for total volatile organic compounds (VOCs). While groundwater impacted by PCE and its daughter products has been
identified on site, soil assessment activities have not identified a significant soil source area within the former Univar parcel
that would explain the observed patterns and magnitude of groundwater impacts beneath the Site. Furthermore, there has
never been a reported release of chlorinated solvents at the Site.
However, a possible up gradient source has been identified. The former Boggs & Company (Boggs) facility, currently being
managed through the North Carolina Dry Cleaning Solvent Cleanup Act (DSCA) Program under Site ID DC600010, is located
directly north and up gradient of the Site. A review of publically available documents has indicated that a release of PCE was
identified on the Boggs property in 1990, with numerous phases of assessment and remediation having been completed in
subsequent years. A review of publicly available records does not indicate that horizontal delineation is complete for the
Boggs release. However, a downgradient residential water supply well at 3800 Glenwood Drive, which tested positive for
chlorinated solvents in 1990, was permanently abandoned using financing originating from the Boggs facility according to the
Report of Groundwater and Assessment and Soil Venting Pilot Test, submitted by Environmental Investigations to NC DEQ
(1993).
To evaluate the potential for off -site COCs originating at the Boggs facility to migrate onto the former Univar parcel and
beyond, a preliminary fate and transport (F&T) model has been developed. The F&T modeling software chosen for the
1/4

Memorandum
development of Site performance standards was the Risk Based Corrective Action (RBCA) Toolkit for Chemical Releases —
Version 2.52, developed by Groundwater Services, Inc. The underlying Domenico equations used by the RBCA Toolkit are
the same used in the ASTM (E-2081) RBCA standard and the RBCA Toolkit is an industry standard for F&T modeling. In
addition to the Domenico equations, the RBCA Toolkit contains a series of equations (including soil and groundwater source
depletion, ASTM soil leaching with decay options, and dual -equilibrium desorption) to conservatively predict contaminant
concentrations at a point of exposure (POE) consistent with standards developed under ASTM that are protective of human
health and the environment.
The off -site groundwater and soil contaminant source area from which the F&T evaluation was performed was selected to be
the AST and dispenser area (area of monitoring well MW-1) on the Boggs facility which is identified on Figure 1. Parameters
used in the preliminary F&T model, as well as a brief description of the source of the parameter, are illustrated on Table 1.
Three separate points of exposure (POEs) located downgradient of monitoring well MW-1 and the soil contaminant source
area were chosen for inclusion in the fate and transport model, which are as follows:
Site Monitoring Well MW-4A —This well is located on the Site approximately 270 feet downgradient of the
understood Boggs source area. Contaminant concentrations in groundwater sampled from this monitoring
well have historically been elevated and average approximately 2 percent the solubility of PCE. This POE
was selected to evaluate if contaminant concentrations from the Boggs soil contaminant source area could
result in the observed dissolved phase contaminant concentrations in Site monitoring well MW-4A.
Sunshine Daycare & Preschool — The preschool is located approximately 650 feet downgradient of the
understood Boggs soil contaminant source area and adjacent to the Site. The Sunshine Daycare and
Preschool was selected as it is the nearest downgradient sensitive receptor to the Site as well as the Boggs
property. To date, the daycare owner has refused access to this property. Therefore, the groundwater
impacts for this POE are represented by MW-12R at the property boundary.
Unnamed Tributary to Stewart Creek — The unnamed tributary is located approximately 1,450 feet
downgradient of the understood Boggs soil contaminant source area and approximately 850 feet
downgradient of the Site. The unnamed tributary was selected as it is the nearest downgradient surface
water body. PCE has been detected in this tributary at a maximum concentration of 99.3 micrograms per liter
(Ng/L), and as high as 190 pg/L in pore water (or Henry Push Point) samples installed to measure the
concentration of PCE in the groundwater entering the tributary.
The results of the F&T model for the off -site soil and groundwater source, depicted on Figures 2 and 3, indicate that
contaminant concentrations observed in groundwater samples collected in proximity to the three POEs listed above are
generally consistent with the predicted contaminant concentrations calculated as part of the fate and transport modeling
effort. Higher observed concentrations of TCE are likely a result of reductive dechlorination, which is not accounted for in the
F&T model.
A similar F&T model was generated using the former drum storage area on the Univar parcel, represented by Advent soil
boring DPT-22, as an onsite soil contaminant source area. Parameters used in this F&T model, as well as a brief description
of the source of each parameter, are presented in Table 2. Monitoring well MW-4A is up gradient of this potential source
location and was therefore not selected as a groundwater POE for this model. The two off -site POEs, the Sunshine Daycare
& Preschool (300 feet downgradient) and the unnamed tributary to Stewart Creek (1,100 feet downgradient) were used for
this model.
The results of the F&T model for the onsite soil source, depicted on Figure 4, indicate that contaminant concentrations
observed in groundwater samples collected in proximity to the two off -site POEs are substantially greater than the predicted
contaminant concentrations calculated by the model. This indicates that the PCE detected on the downgradient property
boundary in monitoring well MW-12R, and off -site points further downgradient such as the unnamed tributary, come from a
source significantly larger than any soil source detected at the Site.
A comprehensive display of data is displayed on Figure 5, illustrating a cross sectional view of the PCE modeled
concentrations from the off -site soil and groundwater sources, and the onsite soil source.

Summary
While groundwater impacted by PCE and its daughter products has been identified at the former Univar parcel, on -site soil
assessment activities completed to date have not identified a significant soil source area at the property that would explain
the observed patterns and magnitude of groundwater impacts beneath the Site. However, the former Boggs & Company
facility (DSCA Site ID DC600010) has been identified as a potential up gradient source of PCE contamination. Furthermore,
the results of the F&T models, depicted on Figures 1, 2, 3, 4 and 5 indicate that PCE concentrations observed in
groundwater samples collected in proximity to the three POEs listed above are most consistent with the predicted
contaminant concentrations calculated utilizing up gradient soil and groundwater source areas. Therefore, the Boggs facility
is the most likely actual source for the PCE detected at these POEs as demonstrated by:
The direction of groundwater flow indicates that the Boggs facility is located hydraulically up gradient of the
Site and the three POEs;
The POE concentrations of PCE and daughter products calculated using the up gradient source area F&T
model are consistent in respect to the magnitude of observed contaminant concentrations at each POE; and
The POE concentrations calculated using the onsite source area F&T model are insufficient to correspond to
the magnitude of observed contaminant concentrations at the Sunshine Daycare & Preschool POE.
It should be noted that the Domenico groundwater model utilized as part of this evaluation does not account for physical
and/or biological mediated contaminant degradation that may be occurring naturally in the subsurface as the contaminants
migrate between the source area and the points of exposure. Subsequently, the modeling results are very conservative and
do not include any loss of contaminant mass via chemical or biological natural attenuation processes.
Thank you for this opportunity to provide this memorandum of a preliminary F&T groundwater model. Please let us know if
you have any further questions of comments.

Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the
calculation which have not been rounded.
J Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
L-03 Laboratory fortified blank/laboratory control sample recovery is outside of control limits. Reported value for this
compound is likely to be biased on the low side.
L-05 Laboratory fortified blank/laboratory control sample recovery is outside of control limits. Reported value for this
compound is likely to be biased on the high side.
V-05 Continuing calibration did not meet method specifications and was biased on the low side for this compound.
V-34 Initial calibration verification (ICV) did not meet method specifications and was biased on the low side for this
compound. Reported result is estimated.
Z-01 Compound fails the method requirement of 70-130% recovery for the LCS. Is classified by the lab as a difficult
compound and passes the in house limits of 50-150%.

** - Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate
carcinogenic risk or hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard of 0.15 µg/m3.
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Risks are calculated for these values
if indoor air concentrations are entered and indoor air screening levels have been established, but it should be noted that detections of these
chemicals are likely not associated with vapor intrusion.
All concentrations are in uQ/m3

** - Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate
carcinogenic risk or hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard of 0.15 µg/m3.
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Risks are calculated for these values
if indoor air concentrations are entered and indoor air screening levels have been established, but it should be noted that detections of these
chemicals are likely not associated with vapor intrusion.

** - Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate carcinogenic risk
or hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard of 0.15 µg/m3.
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Risks are calculated for these values if indoor
air concentrations are entered and indoor air screening levels have been established, but it should be noted that detections of these chemicals are likely not
associated with vapor intrusion.

Air
** - Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate carcinogenic risk
or hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard of 0.15 µg/m3.
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Risks are calculated for these values if indoor
air concentrations are entered and indoor air screening levels have been established, but it should be noted that detections of these chemicals are likely not
associated with vapor intrusion.
All concentrations are in u2/m3
