1.0 PROJECT INFORMATION
The site is currently comprised of one parcel identified as Mecklenburg Parcel ID No. 07307210
located in Charlotte, Mecklenburg County, North Carolina. The site is owned by CBG Real
Estate, LLC and is approximately 0.332-acres in size and is occupied by a 5,946 square foot
commercial building and associated parking areas.
The location of the Site is depicted on Figures 1 and 2.
2.0 PREVIOUS INVESTIGATIONS
ECS conducted a Phase I Environmental Site Assessment (ESA) of the site on April 5,
2017. It appears the site was developed as a commercial property circa 1955, including a
‘cold storage’ building depicted on a 1969 Sanborn Map. Refrigerants, including Freon,
ammonia, and glycols are a potential contamination source. A review of the 1929, 1951,
1953, 1962, and 1969 Sanborn Maps depict off-site sources of contamination in close
proximity to the site including the presence of “G.T’s (gas tanks)” west-northwest of the site,
a welding and auto repair facility north-northwest of the site, and a used auto facility
northeast of the site across West Catherine Street. ECS concluded the historic use of the
site as a cold storage facility and the nearby off-site sources of contamination to be RECs
of the site.
ECS conducted a groundwater assessment of the site in May 2017. Assessment activities
included collection of groundwater samples to evaluate the potential for impacts associated
with the RECs identified in the Phase I ESA Report.
ECS collected four groundwater samples via groundwater sampling direct-push technology
(DPT) probes. The four borings were advanced on the site, two along the northeast side of the
building (GW-1 and GW-2), and two adjacent to the street (GW-3 and GW-4). The borings were
also installed downgradient of the offsite sources of environmental concern. Laboratory
analysis of the groundwater samples collected from borings GW-2, GW-3, and GW-4 detected
ammonia at concentrations ranging from 0.13 mg/L to 0.37 mg/L which is below the North
Carolina Interim Maximum Allowable Concentration (IMAC) of 1.5 mg/L. Ammonia was not
detected in the sample collected from GW-1. Laboratory analysis of the samples collected from
GW-1 and GW-2 detected tetrachloroethene (PCE) at concentrations above the North Carolina
2L Groundwater Quality Standard (NC2LGWQS) but below the Residential Vapor Intrusion
Screening Levels (VISLs). The sample collected from GW-3 detected Methyl-tert-Butyl-Ether
(MTBE) at a level below the NC2LGWQS. Analysis of the sample collected from GW-4
detected isopropyl ether (IPE) at a concentration below the NC2LGWQS and MTBE at a
concentration above the NC2LGQS but below their respective VISLs. Both IPE and MTBE are
associated with unleaded gasoline.
The location of the groundwater samples are shown on Figure 2 and a summary of the
groundwater analytical results are summarized in Table 1. Depth to groundwater measured on
the day of the assessment was approximately 25 feet below grade.

3.0 OBJECTIVE OF THE WORKPLAN
The objective of the work plan was to evaluate the potential for a vapor intrusion concern for the
future use of the site and to obtain volatile organic compounds (VOC) and semi-volatile organic
compounds (SVOC) and total RCRA metal concentrations in the soil at the site. The soil and
soil gas sampling was conducted in general accordance with the North Carolina Department of
Environmental Quality’s (NCDEQ) Vapor Intrusion Guidance (April 2014) and the NCDEQ
Inactive Hazardous Site Program’s Guidelines for Assessment and Cleanup (October 2015).
The sampling plan was discussed during a telephone call with Mr. Bill Schmithorst with the
NCDEQ Brownfields Program on September 25, 2017. ECS proposed the samples be collected
in the area for the proposed building pad to “forecast” worse case conditions that might develop
under the proposed building. To determine this, three exterior soil gas samples were proposed.
In addition to the soil gas samples, ECS collected three soil samples for analysis of VOCs,
SVOCs, and total RCRA metals. The work plan was approved by the NCDEQ on January 19,
2018.
4.0 SAMPLE COLLECTION
4.1 Soil Gas Samples
Number and Sample Location
ECS collected samples from three locations across the site (SG-1 through SG-3). The exterior soil
gas samples were collected from a depth of 5 feet below grade. The approximate locations of the
samples are shown on Figure 2.
Probe Placement and Sample Collection
On January 30, 2018, ECS mobilized to the site to install the soil gas probes. Prior to
advancing the borings, the asphalt and gravel was removed with a core drill. The exterior soil
gas samples were collected by advancing a decontaminated hand auger to a depth of 5 feet
below the ground surface (bgs). The soil samples collected in the hand auger were screened in
the field with a photo-ionization detector (PID). Once the boring reached termination depth,
dedicated soil gas probes consisting of Nylafow tubing and an air stone was lowered into the
boring. Approximately one foot of clean coarse sand was placed around the air stone. A seal
consisting of three feet of bentonite powder was hydrated with distilled water. The soil gas
probe was allowed to stabilize for a minimum of 24 hours before the soil gas sample was
collected. Upon returning to collect the samples on January 31, 2018, ECS observed that the
probe for SG-3 had been vandalized and pulled from the boring. A second boring, placed
adjacent to the first boring, was redrilled on February 2, 2018. ECS returned to the site on
February 3, 2018 to collect the sample from SG-3.
A dedicated disposable syringe was used at each sample location and connected to the tubing
to purge the tubing and annular space around the sample probe. Three volumes of the tubing
and annualr space were purged prior to sample collection. As the tubing was purged, evidence
of water entering the tubing was not noted. Following purging, the tubing was connected to a
400 ml Summa canister, which was used to collect the sample. The Summa canister was fitted
with a flow regulator. The flow rate for both purging and sample collection was 0.2 liters per
minute. The pressure in the canister was recorded before and after sample collection while

making sure the vacuum did not reach zero. Other parameters that were measured included
ambient temperature before and after sample collection and recent weather conditions. Prior to
sample collection a shut-in test was conducted to assess for leaks in the fittings and regulator.
The purge volume, sample collection time, shut-in test results, and canister vacuum readings
prior to and after collection are summarized on the Soil Gas Field Sampling Forms, included in
Appendix E. On the day of the sampling, the weather was sunny and approximately 44 degrees
Fahrenheit.
Leak Detection
Prior to collecting the soil vapor samples, laboratory grade helium gas was used as a quality
assurance control measure to confirm the integrity of the probe seal at each sample location. A
plastic cylinder (approximately 1.75 quarts) was placed and sealed over the sampling point and
filled with laboratory grade helium. The probe point tubing and tracer gas tubing was placed
through the cylinder wall via rubber grommets. The cylinder was placed on a 4-inch rubber
gasket and held securely to the slab with a heavy weight. During the purging stage, the cylinder
was flooded with laboratory grade helium via the hose placed through the cylinder wall. A
Model MGD-2002 Multi-Gas Leak detector was connected to the probe tube and the air stream
being purged will be measured for helium. A helium concentration of less than five percent
helium was considered acceptable. If concentrations greater than five percent helium were
measured, the probe tube seal was reseated and the leak detection process was repeated. The
results of the helium field check are summarized on the Soil Gas Field Sampling Forms,
included in Appendix E.
Sample Analysis
Following sample collection, the canisters were labeled and maintained under chain-of-custody
until delivered to H&P Mobile Geochemistry Inc. in Carlsbad, California. A Chain-of-Custody
document was utilized throughout the collection and transportation of the samples. Each
sample was analyzed for VOCs using EPA Method TO-15. The laboratory results were
reported at or below the applicable vapor intrusion screening levels (VISL) and J Flags were
reported if detected.
Following collection of the soil gas samples, the probes were removed and the borings were
properly abandoned and capped with asphalt.
Quality Control
One duplicate sample (DUP) of sample SG-1 was collected and analyzed for the same
compounds using EPA Method TO-15.
4.2 Soil Samples
Three soil borings (SB-1 through SB-3) were advanced to a depth of 5 feet below the ground
surface and borings locations are depicted on Figure 2. A soil sample was collected from each
boring between the ground surface and a depth of 5 feet. More specifically, as the soil borings
were advanced, the soil was classified in the field by an ECS professional and screened for volatile
organic vapors using a PID. Visual signs of a release such as staining were noted and placed on
the soil bore log. The soil sample from each boring showing the greatest PID reading was selected

for analysis. Each sample was packaged and submitted to a North Carolina certified laboratory and
analyzed for VOCs and SVOCs using EPA Method 8260 and 8270, respectively, and total RCRA
metals using EPA Methods 6020/7470/7471. One sample was analyzed for hexavalent chromium
using EPA Method 7196A. The laboratory results were reported at or below the
Industrial/Commercial Preliminary Health-based Soil Remediation Goal (PSRGs) and J Flags
were reported.
Quality Control
One duplicate sample was collected and analyzed using VOCs and SVOCs using EPA Method
8260 and 8270, respectively, and total RCRA metals using EPA Methods 6020/7470/7471. A
Level II QA/QC package was requested from the laboratory.
5.0 RESULTS
5.1 Soil Gas Analysis
The results of the helium field check did not detect helium above 1 percent in the samples. The
shut in test did not detect breaches in the sample train. The PID did not detect organic vapors
above background and there was no visual evidence of staining. The results are summarized
on the Soil Gas Sampling Form, included in Appendix E.
Laboratory analysis of the soil gas sample collected from SG-3 detected tetrachloroethene
(PCE) at a concentration of 470 ug/m3 which is above the Residential Soil Gas Screening Level
(SGSL) of 280 ug/m3 but below the Non-Residential SGSL of 3,500 ug/m3.
Various other VOCs were detected above the laboratory reporting limits in the samples
collected, but at concentrations below their respective Residential SGSLs.
Quality Control
One duplicate sample (DUP) was collected from SG-1 and analyzed for the same compounds
using EPA Method TO-15. The compounds detected in the duplicate sample were similar to
those detected in SG-1.
The results are summarized in Table 2 and the laboratory report is included as Appendix C.
Risk Calculator
The North Carolina Department of Environmental Quality Risk Calculator (August 2016) was
used on the soil gas results from all the soil gas sample locations. The constituents from each
of the three samples were placed in the calculator to determine a site risk. The vapor intrusion
calculator was run for a non-residential worker.
The calculator determined the vapor intrusion risk was not exceeded for a non-residential
worker at each of the sample locations. The Summary of Risk Assessment Output sheet for the
combined sample locations is included in Appendix F.

5.2 Soil Sample Analysis
Laboratory analysis of the soil sample collected from SB-3 detected PCE at a concentration of
0.0096 mg/kg, which is below the Residential Use Preliminary Soil Remediation Goal (PSRG) of
17 mg/kg.
Laboratory analysis of the three soil samples detected arsenic at concentrations above the
Residential Use Health-Based Preliminary Soil Remediation Goal (PSRG) of 0.68 mg/kg.
Arsenic was detected in SB-1 and SB-3 at a concentration of 3.3 mg/kg and 4.1 mg/kg, which
are above the Industrial Health-Based PSRG of 3.0 mg/kg. The arsenic detected in the soil
samples reflect naturally occurring concentrations.
Laboratory analysis did not detect chromium VI in sample SB-1 above the reporting limit.
Laboratory analysis detected chromium at concentrations above the reporting limits; however,
based on the chromium VI results, it is ECS’ opinion that the chromium detected in the samples
is chromium III. The concentrations did not exceed the residential PSRG. The chromium in the
samples likely reflect naturally occurring concentrations of chromium.
Various other metals were detected at concentrations above the laboratory reporting limit but
below their respective Residential PSRGs.
SVOCs were not detected in the samples collected at concentrations above the laboratory
reporting limit.
A summary of the soil sample analytical results is included as Table 3 and the laboratory report
is included as Appendix D.
Quality Control
One duplicate sample (SB-1 duplicate) was collected from SB-1 and analyzed for the same
compounds. The compounds detected in the duplicate sample were similar to those detected in
SB-1.
The results are summarized in Table 3 and the laboratory report is included as Appendix D.

6.0 CONCLUSIONS
Based on the results of the soil and soil gas assessment of the site, ECS has the following
conclusion:
The soil on the site has not been impacted by past site use and will need to be handled
and managed/disposed/reused in accordance with an Environmental Management Plan
(EMP).
Based on the concentrations of the soil gas analysis which are below non-residential
SGSL’s, and the NCDWM vapor intrusion risk calculation below the residential criteria,
vapor intrusion mitigation does not appear needed under the building due to proposed
non-residential development on the first level.
