1.0 SITE INFORMATION
The site is located at 801-829 West Lee Street in Greensboro, Guilford County (Figure 1). The NC
Brownfields Program determined that the site was eligible for admission into the NC Brownfields
Program as noted in their Letter of Eligibility dated May 10, 2012. The North Carolina Brownfields
Group notified Weidl Properties II, LLC, the Prospective Developer (PD), on January 17, 2013 of
additional assessment requirements that would need to be completed to fill environmental data
gaps.
According to the notice, dry cleaning is currently conducted on-site, and that the dry cleaning facility
currently uses tetrachloroethylene (PCE) in current operations. Based on this information, the
Brownfields agreement will require that PCE or other chlorinated solvents and any daughter
products not be used in future operations at the site. The notice states that the property is currently
registered with the North Carolina Dry Cleaning Solvent Cleanup Program (DSCA) due to its past
and current use of a portion of the site for dry cleaning purposes. According to the notice, soil and
groundwater assessment to address dry cleaning solvent releases will be developed and
implemented by the DSCA Program and are not included in the proposed scope of services below.
Based on a review of historical information included with the Brownfields Application, potential
additional contamination sources at the site include former metal fabrication and possible electro
plating facility operating on a portion of the site, rug cleaning operations, and an underground
storage tank (UST) of unknown volume or contents. The notice has determined that these
contamination sources can adequately be assessed following planned demolition of operations at
the site and has requested a Work Plan outlining the assessment phase of the Brownfields
Agreement.
ECS was contracted by Mr. Robert Weidl of Weidl Properties, LLC to conduct sub-slab soil gas
sampling in accordance with the Work Plan (dated March 20, 2014) approved by the North
Carolina Brownfields Group.
2.0 FIELD INVESTIGATION
2.1 Probe Placement
ECS personnel mobilized to the site on April 15, 2014 (not April 19 as indicated on the chain-of-
custody) to collect three sub-slab soil gas samples. Three sub-slab samples (SG-2A, SG-4 and
SG-5) were collected inside the building at the approximate locations shown on Figure 2. Prior to
drilling the probe holes, the floor was inspected for cracks, joints, and other floor penetrations.
The holes were placed at least three feet from any of these penetrations. The samples were
collected by drilling a 3/8-inch hole through the slab. The holes extended through the slab into
the underlying gravel sub-base. ECS field personnel placed a soil vapor probe into the hole and
down into the gravel. The probe was constructed of 1A-inch stainless steel tubing and a 1A-inch
stainless steel valve with Swag-Lok® fittings. The annular space around the tubing and concrete
were sealed with inert non-VOC emitting putty. A section of Teflon tubing was connected to the
stainless steel probe.

2.2 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. A plastic cylinder
(approximately 1.75 quarts) was placed and sealed over the sampling point and purged with
laboratory grade helium. The probe point tubing and tracer gas tubing was placed through the
cylinder wall via 3/16-inch rubber grommets. The open end of the cylinder was placed on a
rubber seal and held securely to the slab with a heavy weight. As the cylinder was flooded with
laboratory grade helium via the hose placed through the cylinder wall, the probe tubing was
connected to a Model MGD-2002 Multi-Gas Leak detector and the air stream being purged was
measured for helium. A helium concentration of less than five percent helium is considered
acceptable. If a concentration greater than five percent helium was measured, the probe tube
seal was reseated and the leak detection process was repeated. Helium was not detected during
the pre-sampling checks performed at each sample location.
2.3 Sample Collection
After the leak test was completed, the cylinder was removed and a Gilean vacuum pump was
connected to the probe tubing to purge the probe and tubing. The vapor probe and tubing was
purged at a rate of 0.2 Umin by removing three volumes of the probe and associated tubing. The
tubing was then connected to a six-liter Summa canister. The soil gas sample was collected
using a Summa canister with a regulator and vacuum gauge. The sample was collected at a flow
rate of 0.2 Umin. The vacuum in the canister was measured and recorded at the beginning and
the end of the thirty minute sampling cycle. Following sample collection, the canister was labeled
and shipped via FedEx to Con-Test Analytical Laboratories (Con-Test) in East Longmeadow,
Massachusetts to be analyzed for volatile organic compounds (VOCs) using EPA Method T0-15.
A Chain of Custody Record was utilized throughout the collection and transportation of the
samples. The probes were removed and the holes filled with concrete following sampling.
2.4 Quality Control
Upon completion of sampling activities at SG-4, SG-5 and SG-2A, ECS personnel attempted to
collect a duplicate sample from SG-4; however, the canister supplied by the laboratory had lost its
vacuum. A new canister was shipped overnight, and ECS personnel remobilized to the site on
April 16, 2014 and collected a sample adjacent to the sample point for SG-4. The sample was
collected following the above describe techniques. The sample was analyzed by Method T0-15.
3.0 RESULTS
The laboratory analysis detected tetrachloroethene (PCE) in all the soil gas samples. None of the
concentrations detected exceeded the IHSB Non-Residential Vapor Intrusion Screening Level,
dated June 2014. The laboratory analysis detected several degradation products, 1, 1-dichorothene
and trichloroethene, at concentrations greater than their Method Detection Limits (MDLs); however,
the concentrations do not exceed the IHSB Non-Residential Vapor Intrusion Screening Levels. The
sample results are summarized in Table 1. The laboratory analytical data sheets and Chain of
Custody Records are included in Appendix A.

4.0 CONCLUSIONS
Based on the results of the laboratory analysis, ECS concludes the following:
• PCE was detected in all the soil gas samples, with the highest concentration being
detected in sample SG-2A, which was collected near previous sample SG-2. The
concentration of PCE and TCE in SG-2A (740/2.1) were less that of SG-2 (1,300/170).
The concentration of PCE and its degradation products appear higher toward the west
end of the building.
• The soil gas samples (SG-1, SG-2, and SG-3) collected by Hart & Hickman on September
13, 2013 were collected from depths of 27 and 28 feet below land surface. Based on
measurements taken on September 20, 2013 in monitoring wells located in close
proximity to the retail office building, the water table surface varies between 28 and 32
feet below the ground surface.
• The concentration of PCE in soil gas sample SG-2 was 1,300 ug/m3. This sample was
collected at a depth of 28 feet below land surface and approximately one foot above the
water table. The concentration of PCE in soil gas sample SG-2A was 740 ug/m3. This
sample was collected immediately below the slab of the building. Therefore there was an
approximate 60 percent reduction in the concentration of PCE over a distance of 27 feet.
5.0 RECOMMENDATIONS
ECS recommends that a copy of this report be sent to Ms. Sharon Eckard, the Brownfields
Program Manger for her review.

FLAG/QUALIFIER SUMMARY
QC result is outside of established limits.
Wide recovery limits established for difficult compound.
Wide RPO limits established for difficult compound.
Data exceeded client recommended or regulatory level
Percent recoveries and relative percent differences (RPDs) are detennined by the software using values in the
calculation which have not been rounded.
Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
L-0 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.
~ 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.
\1-05 Continuing calibration did not meet method specifications and was biased on the low side for this compound.
Increased uncertainty is associated with the reported value which is likely to be biased on the low side.
V-Of1 Continuing calibration did not meet method specifications and was biased on the high side for this compound.
Increased uncertainty is associated with the reported value which is likely to be biased on the high side.
