1.0 INTRODUCTION
On October 16 through 18, 2006, ERM NC, PC (ERM) performed a Phase II
Environmental Site Assessment (ESA) on behalf of Cherokee Investment
Partners at the Bell property (hereafter referred to as “the subject site“ or
“the subject property”) located at 140 Remount Road, 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 October
2005, as discussed below.
1.1 BACKGROUND
A Phase I ESA was conducted by ERM at the subject property in October
2005. As indicated in the Phase I report, the property was most recently
occupied by Colorcraft Printing Company (1996 to 2004) with the two
story office tower leased to Action Staffing. Prior to 1996, the facility was
owned by The Pritchard Corporation and operated as Pritchard Paint and
Glass. The Pritchard Corporation constructed the facility in 1960 and
retained operations on-site until mid-1995. Prior to development by the
Pritchard Company the site was undeveloped. 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:
• A fuel oil underground storage tank (UST), located adjacent to the
boiler room on the east side of the facility building, was closed in place
in the early 1980s. This UST was not listed in the regulatory database
search. No further information regarding the closure or size of this
tank is available. Because of the lack of information on this fuel oil
UST and potential releases, the fuel oil UST is a potential
environmental concern.
• A former fuel oil aboveground storage tank (AST) was present east of
the boiler room. Any undocumented spills from this AST may have
affected soil or groundwater quality in this area.
• Significant equipment maintenance activities were previously
conducted in the maintenance building at the north side of the
property. It is possible that undocumented spills of petroleum
hydrocarbons or degreasing compounds may have affected soil or
groundwater quality in this area. Intermittent staining was observed
ERM NC, PC 2 REMOUNT ROAD PHASE II REPORT FINAL.DOC
in the asphalt paved parking area. This area was paved in
approximately 1997 when Colorcraft obtained the facility.
• Based on the long-term storage of turpentine and varsol at the subject
property by the Pritchard Paint and Glass Company, it is possible that
undocumented releases of these solvents may have affected soil or
groundwater quality beneath the subject property.
• Several properties within a ¼ mile radius of the subject site were listed
in the database search as sites with documented groundwater or soil
contamination. The topography and suspected regional shallow
groundwater flow direction indicates contamination from these site
should migrate away from the subject site, however, there is potential
for off-site contamination to adversely impact the subject site.
2.0 PHASE II ASSESSMENT ACTIVITIES
On October 16, 2006, ERM supervised the installation of five direct push
(Geoprobe®) soil borings. 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 (RR-SB-1 through RR-SB-3) and three groundwater samples
(RR-GW-2, RR-GW-4, and RR-GW-5) were collected 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
ERM NC, PC 3 REMOUNT ROAD PHASE II REPORT FINAL.DOC
readings, visual and olfactory observations and the suspected depth of the
potential concern.
Soil borings RR-SB-1 and RR-SB-2 was advanced along the southeastern
wall of the site structure in the area of the UST and boiler to assess
potential impacts to soil and groundwater in this area. A soil sample was
collected at approximately 0.25 to 2 feet below ground surface at RR-SB-1
and 2 to 4 feet at RR-SB-2. A third soil boring (RR-SB-3) was advanced
adjacent to the former vehicle maintenance building. A soil sample was
collected from 2 to 4 feet below ground surface at this location. Two
additional soil borings (RR-SB-4 and RR-SB-5) were advanced along the
northwestern property boundary for the purpose of assessing potential
impacts to groundwater from off-site sources. 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. ERM and Prism
Laboratories adhered to appropriate chain-of-custody procedures. Soil
samples RR-SB-1 and RR-SB-2 were analyzed for diesel range organics
(DRO) and gasoline range organics (GRO) by Method 8015B. Soil sample
RR-SB-3 was analyzed for: VOCs by Method 8260, Metals by EPA
Methods 6010B and 7471, and semi-volatile organic compounds (SVOCs)
by Method 8270.
Following the completion of soil sample collection where applicable,
temporary monitor wells were installed in the RR-SB-2, RR-SB-4, and
RR-SB-5 borings. The temporary monitor wells were installed at depths of
9 feet below ground surface in boring RR-SB-2 and 14 feet at RR-SB-4 and
RR-SB-5. 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. 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-
ERM NC, PC 4 REMOUNT ROAD PHASE II REPORT FINAL.DOC
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 16.2 feet below ground surface in
RR-GW-4 to 18.7 feet in RR-GW-5. Based on the groundwater elevation
data and local land surface topography, the groundwater flow direction
beneath the subject property appears to be to the southwest toward the
Remount Road/Dunavant Street intersection.
Groundwater samples collected from temporary monitor wells RR-GW-4
and RR-GW-5 were analyzed for VOCs by Method 8260B and Metals by
Methods 6010B and 7471. The groundwater sample collected from the
temporary monitor well RR-GW-2 was analyzed for VOCs by Method
8260B and SVOCs by Method 8270. Samples collected from each
temporary well were labeled with an identification of GW, i.e., the sample
collected and labeled RR-GW-2 is the groundwater from the boring
labeled RR-SB-2.

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 Water Quality – Aquifer Protection Section’s Soil-to-
Groundwater Cleanup Levels, Division of Waste Management (DWM) UST
Section’s Maximum Soil Contaminant Concentrations (MSCCs) or Division
of Waste Management – Superfund Section’s Inactive Hazardous Sites
Branch Remediation Goals (IHSB RG) levels. ERM also compared the
metals concentrations in soils to the common range of naturally occurring
metals in soils, as published in EPA’s Hazardous Waste Land Treatment, SW-
874, Table 6.46, dated April 1983. Also presented for comparison purposes
are naturally occurring concentrations of common metals in the eastern
United States as reported by the United States Geological Survey (USGS).
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 (RR-SB-1 and RR-SB-2) were submitted to the laboratory for
diesel range organics and gasoline range organics analyses. Diesel range
organics were detected in the RR-SB-1 soil sample at 370 milligrams per
kilogram (mg/kg). The NCDENR DWM UST Section’s action level for
diesel range organics is 10 mg/kg. No GRO was detected in either soil
sample.
Soil sample RR-SB-3 was submitted to the laboratory for VOC, SVOC, and
metals analyses. No VOCs or SVOCs were detected in the sample. Low
concentrations of metals were detected in the soil sample. Chromium
(total) was detected at 47 mg/kg which is in excess of the NCDENR
Aquifer Protection Section’s Cleanup Level and DWM UST Section’s
MSCC of 27 mg/kg for this naturally occurring mineral. No potential
source of chromium has been identified in this area and the concentration
detected in the RR-SB-2 soil is within the range of naturally occurring
concentrations in Piedmont soils. No other metals were detected at levels
above the applicable Clean-Up Levels.
ERM NC, PC 6 REMOUNT ROAD PHASE II REPORT FINAL.DOC
Groundwater
The groundwater levels in temporary monitor wells RR-GW-2, RR-GW-4,
and RR-GW-5 ranged from 16.2 to 18.7 feet below ground surface.
Groundwater samples collected from the temporary wells RR-GW-4 and
RR-GW-5 were submitted to the laboratory for VOC and metals analyses.
Xylene, toluene, and 1,3-dichlorobenzene were detected in RR-GW-5 at
levels below the applicable North Carolina Groundwater Standards. No
other VOCs were detected in these groundwater samples. No on site
source of the VOCs detected in the groundwater at the subject property
has been identified. Low concentrations of mercury, barium, chromium,
and lead were detected in the groundwater samples in concentrations
below the applicable North Carolina Groundwater Standards. No on-site
source of these metals has been identified at the subject property. These
metals were detected in the site soils and their presence in the
groundwater samples may be attributed to their natural occurrence in site
soils.
The groundwater sample collected from the temporary well RR-GW-2 was
submitted to the laboratory for VOC and SVOC analysis. No VOCs or
SVOCs were detected in this groundwater sample.
4.0 SUMMARY AND CONCLUSIONS
On October 16-18, 2006, ERM conducted a Phase II ESA to evaluate
subsurface conditions at the Bell property located at 140 Remount Road,
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. Diesel range organics were detected in
one sample at 370 mg/kg which exceeds the NCDENR UST Section
Action Level of 10 mg/kg. This sample was collected adjacent to the
closed-in-place UST located along the southeast corner of the building.
The elevated concentration of DRO reported in this soil sample indicates
that a release of petroleum hydrocarbons has occurred in the vicinity of
the former heating oil UST. These data should be presented to the owner/
operator of the UST for submittal to the NCDENR UST Section for their
review. Additional soil sampling in the vicinity of the former UST may be
required by NCDENR to evaluate the horizontal and vertical extent of the
petroleum-affected soil.
Chromium was detected in one sample at 47 mg/kg which slightly
exceeds the NCDENR Aquifer Protection Section’s Cleanup Level and
DWM UST Section’s MSCC of 27 mg/kg. No potential source of
chromium has been identified in this area and the detected concentration
is within the range of naturally occurring concentrations of chromium in
Piedmont soils. No additional investigation or remediation of the
chromium detected in the soil in this area is warranted. No other metals,
VOCs, DRO, or GRO were identified in excess of applicable NCDENR
Cleanup Levels.
Three groundwater samples were collected from temporary monitor wells
installed at the soil boring locations. The groundwater flow direction
beneath the site appears to be to the southwest. No VOCs, SVOCs or
metals were detected in the groundwater samples in excess of the North
Carolina Groundwater Standards.
