1.0 INTRODUCTION
On October 18 through 23, 2006, ERM NC, PC (ERM) performed a Phase II
Environmental Site Assessment (ESA) on behalf of Cherokee Investment
Partners at the Georgia Carolina Products Company, Inc property
(hereafter referred to as “the subject site“ or “the subject property”)
located at 2316 South Boulevard, in Charlotte, Mecklenburg County, North
Carolina. The purpose of the Phase II site investigation was to investigate
potential areas of concern identified during a previous Phase I ESA of the
site conducted by ERM in November 2005, as discussed below.
1.1 BACKGROUND
A Phase I ESA was conducted by ERM at the subject property in
November 2005. As indicated in the Phase I report, a facility building was
constructed in 1938 and occupied by Georgia Carolina Products from 1944
to 2000. Chemicals used in the textile industry were processed on site
from the late 1940s to 2000. Processes included softening, sizing, primary
blending, and cooking of tallow, starch, waxes, mineral based oils, and
polyvinyl alcohol. No reactant chemical processing was conducted on
site. The facility was also formerly used as a distributor of Mobil Oil
brand petroleum products. The location of the subject property is
presented on Figure 1. Figure 2 presents the current site layout. The
Phase I ESA identified the following potential environmental concerns:
• An 8,000-gallon fuel oil underground storage tank (UST) installed in
1966 is located adjacent to the boiler room on the southern wall of the
main facility building. The UST still contains diesel fuel although the
boiler and associated fuel tank are no longer in operation. Potential
historic releases of diesel fuel from this tank could have resulted in soil
and groundwater contamination. The tank should be properly closed
in accordance with North Carolina Department of Environment and
Natural Resources (NCDENR) guidelines.
• The facility was formerly utilized as a Mobil Oil distribution center
when Ray Chemical Company occupied the property in late 1940s and
early 1950s. Undocumented petroleum releases potentially occurring
during this time might have resulted in on-site soil and groundwater
contamination.
ERM NC, PC 2 GEORGIA CAROLINA PHASE II REPORT FINAL.DOC
• Welder’s Supply Company, located directly north of the subject site, is
listed in the database search as containing three USTs. The first UST is
reported to be a 2,000-gallon fuel oil UST installed in May 1956 and
permanently closed in 1985. The second UST is reportedly a 1,500-
gallon fuel oil UST installed in May 1956 and permanently closed in
1985. The third UST is reported to be a 1,000-gallon gasoline UST
installed in May 1956 and permanently closed in 1974. No additional
information was available regarding the closure of these tanks.
Undocumented petroleum releases from these USTs may have
adversely impacted the subject site. However, no soil or groundwater
contamination from these historic USTs has been documented.
• According to a previous Phase I ESA conducted by S&ME
Incorporated in August 2001, the property addressed as 2301 South
Boulevard previously operated as a dry cleaning facility for more than
30 years. This former dry cleaning facility is located approximately 150
feet to the east across South Boulevard and topographically upgradient
of the subject property. Historic releases of chlorinated solvents from
this facility may have adversely impacted the subject site.
• The Columbus Oil Company, located at 2109 South Boulevard, over
one-eighth mile north of the subject site is listed in the Incident
Management Database (IMD) and leaking UST databases. Petroleum
contamination of soil and groundwater was discovered at this site in
1989. The corrective action plan involved a pump and treat method for
addressing petroleum contamination in groundwater. This site has not
received regulatory closure. The inferred direction of groundwater
flow in the vicinity of the subject site is to the southeast. Based on the
close proximity of the Columbus Oil Company, and the inferred
groundwater flow direction, this site has the potential to adversely
affect the subject property.
2.0 PHASE II ASSESSMENT ACTIVITIES
On October 18 and19, 2006, ERM supervised the installation of three direct
push (Geoprobe®) soil borings on the subject property. All three of the
direct push soil borings were converted to temporary monitor wells for
purposes of collecting groundwater samples and identifying the depth to
the water table. Three soil samples (RJ-SB-1 through RJ-SB-3) and three
groundwater samples (RJ-GW-1 through RJ-GW-3) were collected and
submitted for laboratory analysis. An additional groundwater sample
ERM NC, PC 3 GEORGIA CAROLINA PHASE II REPORT FINAL.DOC
was collected from an existing on-site monitor well (2316 Well) and
submitted for laboratory analysis.
The direct push soil borings and temporary monitor wells were installed
by Probe Technology, Inc. of Concord, North Carolina, using direct push,
or Geoprobe® drilling and sampling equipment. The direct push
sampling method uses a small truck or all terrain vehicle mounted
hydraulic jack mechanism to drive a 2-inch diameter hollow steel probe
(macro-core) with a polyethylene soil-sampling sleeve into the ground to
the desired depth prior to sampling. Using the macro-core sampler, soil
samples were collected continuously until the target soil sampling depth
was reached or refusal was met. All downhole sampling equipment was
cleaned via a high-temperature/high-pressure water wash (steam cleaner)
before and between each boring.
Soils were logged in the field by an ERM geologist and screened for the
presence of volatile organic compounds (VOCs) via a photo-ionization
detector (PID) and the headspace field screening method. Soil boring logs
and field screening data and can be referenced in Appendix A. Soil
samples intervals for laboratory analyses were chosen based on PID
readings, visual and olfactory observations and the suspected depth of the
potential concern.
Soil boring RJ-SB-2 was advanced along the eastern property boundary of
the subject property to assess potential impacts to soil and groundwater
from off site sources. A soil sample was collected from this boring at
approximately 2 to 4 feet below ground surface. Soil boring RJ-SB-3 was
advanced in the western portion of the subject property to assess potential
impacts to soil and groundwater from historic uses of the site. A soil
sample was collected from this boring at approximately 2 to 4 feet below
ground surface. One additional soil boring (RJ-SB-1) was advanced
adjacent to the inactive heating oil UST located along the southern wall of
the existing site structure. A soil sample was collected from this boring at
8 to 10 feet below ground surface. In general, the shallow soils at the site
were comprised of clayey silts grading to fine sandy silts at depth.
Soil samples were placed in laboratory-supplied sample containers and
then placed in a cooler with ice for storage and delivery to Prism
Laboratories of Charlotte, North Carolina for analyses. Soil samples RR-
SB-2 and RR-SB-3 were analyzed for volatile organic compounds (VOCs)
by Method 8260. Soil sample RR-SB-1 was analyzed for diesel range
organics (DRO) and gasoline range organics (GRO) by Method 8015B.
ERM and Prism Laboratories adhered to appropriate chain-of-custody
procedures.
ERM NC, PC 4 GEORGIA CAROLINA PHASE II REPORT FINAL.DOC
Following the completion of soil sample collection, temporary monitor
wells were installed in the RJ-SB-1, RJ-SB-2, and RJ-SB-3 borings. The
temporary monitor wells were installed at depths of 19.4 feet below
ground surface in boring RJ-SB-1, 14.5 feet at RJ-SB-2, and 10.9 feet at RJ-
SB-3. These depths represent where the direct push probe encountered
saturated soil for groundwater sampling.
Each temporary monitor well was installed with 1-inch diameter PVC well
screen and riser, filter sand and bentonite seal in general accordance with
North Carolina Well Construction Standards (15A NCAC 2C). Each well
was fitted with locking, expandable well caps. Following construction, all
new monitor wells were developed by purging a minimum of five well
bore volumes from the well utilizing a combination of a new, disposable
bailer and previously decontaminated peristaltic pump. Additionally, a
groundwater sample was collected from an existing on-site monitor well
(2316 well) associated with the closed-in-place mineral oil UST. Available
construction details regarding this existing monitor well are included in
Table 1.
After development, all monitor wells were sampled using low-flow
sampling methods to minimize turbidity present in the samples and to
minimize the volume of groundwater potentially requiring special
handling and disposal procedures. Prior to purging and sampling, depth-
to-groundwater data were recorded for each monitor well. Monitor well
construction details and groundwater elevation data are presented in
Table 1.
The depth-to-groundwater ranged from 20.5 feet below ground surface in
RJ-GW-2 to 25.8 feet in RJ-GW-3. Based on these depth-to-groundwater
elevation data measurements and local land surface topography, the
groundwater flow direction beneath the subject property appears to be to
the northwest toward the light rail line.
Groundwater samples were collected from each temporary monitor well
and the existing monitor well and analyzed for VOCs by Method 8260B
and semi volatile organics (SVOCs) by Method 8270. Samples collected
from each temporary well were labeled with an identification of GW, i.e.,
the sample collected and labeled RJ-GW-1 is the groundwater from the
boring labeled RJ-SB-1.

3.0 ASSESSMENT RESULTS
Soil analytical results are summarized in Table 2 and groundwater
analytical results are summarized in Table 3. Sample locations and
analytical results are illustrated in Figures 3 and 4 for soil and groundwater,
respectively. Soil boring logs including field screening values are presented
in Appendix A. The laboratory analytical data reports are presented in
Appendix B. For comparison purposes, the soil results are compared to the
North Carolina Department of Environment and Natural Resources
(NCDENR) Division of Waste Management Underground Storage Tank
Section’s Maximum Soil Contaminant Concentrations (MSCCs), the
Division of Water Quality – Aquifer Protection Section’s Soil-to-
Groundwater Cleanup Levels or Division of Waste Management –
Superfund Section Inactive Hazardous Sites Branch Remediation Goal
(IHSB RG) levels. These values are shown in Table 2 of this report, as
applicable. Groundwater analytical results are compared to the North
Carolina Groundwater Standards (NC 15A NCAC 2L 0.0202(g)) which are
identified in Table 3.
Soils
Soil samples RJ-SB-2 and RJ-SB-3 were submitted to the laboratory for
VOC analyses. Acetone was detected in RJ-SB-3 below all applicable
North Carolina remediation goals. No other detectable concentrations of
VOCs were reported in either of the soil samples. Soil sample RJ-SB-1 was
submitted to the laboratory for GRO/DRO analysis. No detectable
concentrations of DRO or GRO were reported.
Groundwater
The groundwater levels in temporary monitor wells RJ-GW-1, RJ-GW-2,
and RJ-GW-3 were approximately 24.85 feet, 20.45 feet, and 25.82 feet
below ground surface, respectively. Based on the ground water elevation
data and local land surface topography, the groundwater flow direction
beneath the subject property appears to be to the northwest toward the
light rail line.
VOCs were detected in two of the four groundwater samples collected
from the temporary wells and the existing on-site well. Tetrachloroethene
was detected in the groundwater sample collected from the existing on-
site monitor well (2316 well) at 2.7 micrograms per liter (µg/L). The
North Carolina Groundwater Standard for tetrachloroethene is 0.7 µg/L.
Chloroform was detected in the groundwater sample from RJ-GW-2 at 10
µg/L which is below the North Carolina Groundwater Standard of 70
ERM NC, PC 6 GEORGIA CAROLINA PHASE II REPORT FINAL.DOC
µg/L. No other VOCs or SVOCs were detected in any of the groundwater
samples collected at the site.
No on site source of the tetrachloroethene detected in the groundwater
sample from the existing monitor well (2316 well) at the subject property
has been identified. The nearby closed-in-place mineral oil UST does not
appear to be a likely source of the tetrachloroethene detected in the
groundwater sample. The dry cleaning facility which previously operated
across South Boulevard to the northeast and topographically upgradient
of the subject property may be the source of the tetrachloroethene
reported in this ground water sample.
4.0 SUMMARY AND CONCLUSIONS
On October 18-23, 2006, ERM conducted a Phase II ESA to evaluate
subsurface conditions at the Georgia Carolina Products Company Inc
property located at 2316 South Boulevard, Charlotte, Mecklenburg
County, North Carolina. A summary of the findings of the Phase II ESA is
provided below.
Three soil samples were collected via direct push methods to evaluate soil
quality at the subject property. No VOCs, DRO or GRO was identified in
the soils samples in excess of the applicable NCDENR remediation goals.
Three groundwater samples were collected from temporary monitor wells
installed at the soil boring locations. An additional groundwater sample
was collected from the existing on-site monitor well associated with the
closed-in-place mineral oil UST. Groundwater flow direction appears to
be to the northwest. Tetrachloroethene was detected in the existing on-
site well sample in excess of the North Carolina Groundwater Standard.
The concentration of tetrachloroethene detected is 2.7 µg/L. The North
Carolina Groundwater Standard for tetrachloroethene is 0.7 µg/L. No
potential on-site source of the tetrachloroethene in the groundwater has
been identified in this area. The dry cleaning facility which previously
operated across South Boulevard to the northeast and topographically
upgradient of the subject property may be the source of the
tetrachloroethene reported in this ground water sample. No other VOCs
or SVOCs were detected in the groundwater samples in excess of the
North Carolina Groundwater Standards.
