1.0 PROJECT INFORMATION
The site is located at 511 and 527 West Tremont Avenue in Charlotte, Mecklenburg County, North
Carolina (Figure 1 and Figure 2). The approximate 5.58-acre site is currently occupied by Corey
Transmission Service, Inc. and includes an approximate 17,500-square foot building constructed in 1981
and an approximate 3,600-square foot building constructed in 1988.
ECS conducted a Phase I Environmental Site Assessment (ESA) of the site on August 9, 2017 (ECS Project
No. 49-4913). As a part of the historical and regulatory research conducted during the Phase I ESA, the
following recognized environmental conditions (RECs) were identified:
The current and historical use of the subject site as an automotive repair facility;
The documented soil and groundwater contamination at the site from the July 2006 Phase II ESA
completed by Salem Environmental;
Petroleum odors noted in the soil during the geotechnical assessment conducted by ECS (B-2
from 0-2 feet, B-4 from 0-20 feet, B-8 from 0-12 feet, B-9 from 0-13 feet, and B-10 from 0-8
feet);
The tetrachloroethene (PCE) in the groundwater documented on the Beacham property located
200 feet northeast and topographically upgradient of the site;
The Powers Site State Brownfields Project located on the northern adjacent property; and,
The Steve Lit, Inc. listing located on the eastern adjacent property.
In an effort to determine if the site has been adversely impacted by the RECs identified during the Phase
I ESA and assess the conditions across the site for potential impacts that may be encountered during site
development activities, ECS was contracted to conduct an environmental assessment. Project
information is based on correspondence between Mr. Jason Braga with Icon Residential, Ms. Britney
Barnes with ECS, and the previously cited Phase I ESA.
2.0 SCOPE OF SERVICES
The environmental assessment consisted of collecting soil, groundwater, and soil gas samples. Drilling
activities were conducted using a Geoprobe® drill rig. The subcontractor used for this project was 3-D
Environmental Investigations (3-D). Drilling and sampling activities were conducted on September 21,
2017. A photographic log documenting the field sampling activities is provided in Appendix A.
2.1 Public Utility Locate
Prior to commencing with field activities, ECS contacted North Carolina One-Call to locate/mark public
utilities at the site. Required separation distances between subsurface activities and marked utilities
(typically 30-inches) were maintained during the field activities.

2.2 Temporary Monitoring Well Permit
Prior to commencing with field activities, ECS obtained a monitoring well permit from the Mooresville
Regional office of the North Carolina Department of Environmental Quality (NCDEQ). In addition, ECS
obtained a permit from Mecklenburg County. Copies of these permits are included in Appendix B. In
accordance with the NCDEQ permit, the GW-1 and GW-30 forms (well construction and well
abandonment forms) were submitted to the NCDEQ. The GW-1 and GW-30 forms were completed by
the North Carolina certified well driller.
2.3 Soil Boring Activities
Eight soil borings, SB-1 through SB-8, were advanced across the site. The borings were advanced
adjacent to the onsite buildings and in areas where petroleum odors were noted in soils collected during
the geotechnical assessment. The boring/sample locations are shown on Figure 3.
The soil borings were advanced by hydraulically driving a five-foot long, 1.5-inch diameter sampling
probe into the soil. Prior to advancing each boring, the down hole equipment and Geoprobe® drill rig
were decontaminated utilizing a high pressure steam cleaner and municipal water. The down hole
equipment and drill rig were decontaminated to prevent cross-contamination between boring locations.
Continuous soil samples were collected from each of the soil boring locations using a soil sampling probe
lined with a disposable clear plastic tube. The clear plastic tube was replaced with each five-foot
interval. After the soil sampling probe was driven, the clear plastic tube filled with soil was removed
from the probe and cut open to expose the soil. ECS visually classified the soil collected from each
boring and screened the soil samples for relative levels of volatile organic vapors using a photoionization
detector (PID). A boring log, which includes a description of the soil encountered, the field screening
results, and the depth of sample collection, was prepared for each boring. The boring logs are included
in Appendix D.
Soil samples were collected from the depth that exhibited evidence of impact (i.e. odor, staining, and/or
elevated PID readings). If no evidence of impact was observed, then samples were collected from
various depths to better assess the vertical extent of possible impacts.
2.4 Temporary Monitoring Well Installation Activities
Six borings were advanced for the installation of temporary monitoring wells; however, due to the shallow
depth of weathered bedrock encountered and the lack of groundwater present in the borings, temporary
monitoring wells were installed at two of the six locations. Temporary monitoring wells TW-1 and TW-2
were installed on the northeastern portion of the site on the western and southern side of the building
present in this area. TW-2 was placed in the vicinity of the groundwater impacts identified during the Phase
II ESA completed by Salem Environmental in July 2006. The locations of the temporary wells are shown on
Figure 3.
The temporary monitoring wells were installed in boreholes drilled in a manner consistent with the soil
borings described above. The temporary wells were constructed with one-inch inside diameter Schedule 40
PVC flush-threaded casing and screen. A ten-foot length of slotted well screen with machined 0.010-inch DRAFT

slot widths and a threaded bottom plug was installed at the bottom of each well. The screens were installed
to a depth that intercepted the groundwater surface, as estimated during drilling, or at the top of drilling
refusal. A well construction diagram was prepared for each temporary monitoring well, which are included
on the borings logs in Appendix D.
The depth to groundwater at the site was anticipated to be encountered approximately 30 feet below the
ground surface (bgs); however, groundwater was not encountered prior reaching drilling refusal at four of
the six boring locations. At the locations where groundwater was not encountered, drilling refusal (the top
of partially weathered bedrock) was encountered between six and seven feet bgs. At location TW-1, drilling
refusal was encountered at 15-feet bgs and the depth to groundwater was approximately 7.50 feet bgs. At
location TW-2, drilling refusal was encountered at 22-feet bgs and the depth to groundwater was
approximately 9.35 feet bgs.
Following the completion of the soil and groundwater sampling activities, the temporary monitoring wells
were removed and the borings were properly abandoned.
2.5 Soil and Groundwater Sample Collection
The soil samples were collected from the clear plastic tubes retrieved from the soil sample probe while
the sampler was wearing a new pair of disposable nitrile gloves for each sample collected. The soil
samples were placed directly into laboratory prepared containers.
Groundwater samples TW-1 and TW-2 were collected using a peristaltic pump using new, clean
disposable polyethylene tubing. Groundwater pumped to the surface via the peristaltic pump was
placed directly into laboratory prepared containers while the sampler was wearing a new pair of
disposable nitrile gloves at each of the sampling locations.
The soil and groundwater sample containers were labeled with ECS project number, sample
identification, sample date and time, and requested analytical analysis. The containers were placed into
protective packaging material and placed into a cooler with ice to maintain the samples at
approximately 4 Celsius (C). The groundwater samples were submitted to Prism Laboratories located
in Charlotte, North Carolina (North Carolina Certification # 402) for chemical analysis for volatile organic
compounds (VOCs) and semi-volatile organic compounds (SVOCs) using Standard Method 6200 and EPA
Method 625, respectively. Soil samples were submitted for chemical analysis of total petroleum
hydrocarbons (TPH) diesel range organics (DRO) and gasoline range organics (GRO). ECS maintained
proper chain-of-custody (COC) procedures throughout the sample collection and transportation process.
Copies of the COCs are included in Appendix E.
2.6 Soil Gas Sampling Activities
Five soil gas samples, SG-1 through SG-5, were collected across the site. Sample SG-1 was collected in
the vicinity of SB-3/TW-1 and sample SG-2 was collected in the vicinity of SB-4/TW-2. Sample SG-3 was
collected in the vicinity of SB-6 which was located in the roadway leading to the southern portion of the
site. Samples SG-4 and SG-5 were collected in the vicinity of SB-7 and SB-8 in the southeastern and
southwestern portions of the site, respectively. The sample locations are shown on Figure 3.

The samples were collected by advancing a borehole to a depth of five feet below the ground surface.
The boreholes were advanced using the Geoprobe® drill rig. Once each boring was drilled, a vapor
implant was installed. The vapor implant consisted of Nylaflow tubing attached to a porous ceramic air
stone used to filter the subsurface vapor for particulates as it enters the sampling tube. The annular
space around the filter was filled with clean quartz sand. The annular space above the sand was
backfilled with bentonite and hydrated with distilled water to create a seal.
Prior to collecting the soil gas samples, a leak test was performed at each of the sample locations as a
quality assurance control measure to confirm the integrity of the probe seal. A plastic cylinder was
placed and sealed over the sampling point and purged with laboratory grade helium. The vapor implant
sample tubing and tracer gas tubing were placed through the cylinder wall via 3/16-inch rubber
grommets. During the purging stage, the cylinder was flooded with helium via the tracer gas tubing
placed through the cylinder wall. A Model MGD-2002 Multi-Gas Leak detector was connected to the
sample tubing and 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. Helium was not detected from the
sample tubing during the leak testing. After the leak test was completed, a vacuum syringe was used to
remove three volumes of air from the sample tubing prior to collection of the soil gas sample.
The soil gas samples were collected using a 400-mL Summa canister with a regulator and vacuum gauge.
The samples were collected at a flow rate of 0.2L/min. The vacuum was measured and recorded at the
beginning and the end of the approximate two-minute sampling cycle.
Following sample collection, the canisters were labeled and shipped to H&P Mobile Geochemistry
Laboratory (H&P) in Carlsbad, California to be analyzed for VOCs using EPA Method TO-15. ECS
maintained proper chain-of-custody (COC) procedures throughout the sample collection and transportation
process. A copy of the COC is included in Appendix E.
Following the completion of the sub-slab soil gas sampling, the vapor implants were removed and the
boreholes were backfilled.

3.0 RESULTS
3.1 Soil Sample Results
Laboratory analysis of soil samples detected DRO at concentrations ranging from 0.6 mg/kg (SB-1) to
389.6 mg/kg (SB-7). With the exception of SB-7, the samples collected did not detect DRO at
concentrations that exceed the North Carolina Action Level of 100 mg/kg. GRO was detected in borings
SB-2, SB-4, SB-5, and SB-8 at concentrations ranging from 1.1 mg/kg to 8.5 mg/kg which are below the
North Carolina Action Level of 50 mg/kg. GRO was not detected in the samples collected from SB-1, SB-
3, SB-6, or SB-7. The concentrations and their comparison criteria are summarized on Table 1. The
sample locations are depicted on Figure 3.
A summary of the laboratory analytical results for soil are provided on Table 1. The laboratory data
sheets are included in Appendix E.
3.2 Groundwater Sample Results
Laboratory analysis of the groundwater sample collected from temporary well TW-1 detected three
SVOCs, fluoranthene, docosene, and hexadecanoic acid, at concentrations below their respective North
Carolina 2L Groundwater Quality Standards. VOCs were not detected in the sample collected from TW-
1.
Laboratory analysis of the groundwater sample collected from temporary well TW-2 detected three
SVOCs (hexadecanoic acid, cyclic octaatomic sulfur, and eicosanol) and various petroleum related VOCs
at concentrations below their respective North Carolina 2L Groundwater Quality Standards.
A summary of the laboratory analytical results for the groundwater are provided on Table 2 and the
laboratory data sheets are included in Appendix E.
3.3 Soil Gas Sample Results
Laboratory analysis of soil gas samples detected numerous petroleum-related VOCs in the samples
collected from SG-1 and SG-3 through SG-5 at concentrations above their respective laboratory
reporting limits, but below both their respective residential and non-residential North Carolina Soil Gas
Screening Levels (SGSLs). The soil gas sample collected from SG-2 detected numerous constituents at
levels below their applicable screening levels; however, Methyl-tertiary-butyl-ether (MTBE), m,p-
Xylenes, and 1,2,4-Trimethylbenzene were detected at concentrations above their respective residential
SGSLs, but below the non-residential SGSLs. The detected constituents were primarily petroleum related
with the exception of one chlorinated VOC, tetrachloroethene, which was detected in samples SG-4 and
SG-5 at concentrations below its applicable comparison criteria.
A summary of the soil gas sample results are provided on Table 3. The laboratory data sheets are
included in Appendix E.

4.0 CONCLUSIONS
Based on the results of the environmental assessment, ECS concludes the following:
A total of eight soil samples, two groundwater samples, and five soil gas samples were collected
across the site. Four additional groundwater samples were attempted; however, drilling refusal
was encountered prior to intercepting the water table. The depth to groundwater at location
TW-1 and TW-2 was approximately 7.5 and 9.35 feet bgs, respectively.
Based on the visual evidence and PID readings during the soil sampling, no obvious indications
of gross impacts were observed at the locations sampled, except for in the soil sample collected
from SB-7. DRO was detected at a concentration of 389.6 mg/kg, which is above the North
Carolina Action Level of 100 mg/kg.
Various VOCs and SVOCs were detected in the groundwater sample at concentrations above the
laboratory reporting limits, but below the applicable comparison criteria.
Several petroleum related constituents and one chlorinated solvent were detected in the soil
gas samples collected across the site at concentrations above the laboratory reporting limits,
but below the applicable comparison criteria by an order of magnitude or more except for in
sample SG-2. MTBE and m,p-Xylenes were detected at concentrations above their applicable
Residential SGSLs. This data indicates a completed exposure pathway to vapors is present at the
site that may result in the need for mitigation efforts during site redevelopment.
5.0 RECOMMENDATIONS
Based on the results of the environmental assessment, ECS recommends the following:
TPH DRO was detected in the soil sample collected from location SB-7 at a concentration above
the North Carolina Action Level. This sample was located in the southeastern portion of the site
where junkyard cars are stored and in the vicinity of the geotechnical boring B-10. Based on the
concentration above the Action Level, a reporting requirement to the state exists. Based on the
concentration of DRO at this location, ECS recommends additional assessment in an effort to
better define the extent of impacted soil that may need to be managed during proposed
development activities.
Based on the detections of petroleum related constituents in the soil gas sample collected from
the northeastern portion of the site and lack of consistent groundwater detections, ECS also
recommends additional soil and groundwater sampling in this area of the site to further assess
the source of the vapor impacts.
