Dear Ms. Minnich:
Wood Environment &Infrastructure Solutions, Inc.(Wood) is pleased to submit this Report of
Supplemental Soil-Gas Sampling and Analysis for the above-referenced site located in Charlotte,North
Carolina.Included in this report is an outline of our understanding of the project information, description
of the assessment activities, analytical results, conclusions and recommendations. The following was
completed in accordance with the Work Plan (dated February 15, 2019)and an email from yourself (dated
May 15, 2019) regarding locations of the two additional soil-gas samples.
Project Information
On July 19, 2017,Wood (as Amec Foster Wheeler)installed four temporary sub-slab soil-gas sampling
points (SG-1 through SG-4) through the concrete floor slab in the existing office building (1100 S. Tryon
Street)to a depth of about six inches beneath the base of the slab. The 2017 sampling locations are
shown on Figure 1.Wood collected soil-gas samples from these points.The laboratory analysis of the
four sub-slab soil-gas samples identified concentrations of several Volatile Organic Compounds (VOCs)
which exceeded their respective laboratory reporting limits. However, the concentrations measured did
not exceed their respective North Carolina Department of Environmental Quality (NCDEQ), Division of
Waste Management (DWM), Brownfields Program (BFP)Non-Residential Soil-Gas Screening Levels
(SGSLs).

In February 2019, Wood collected four soil-gas samples from beneath the footprint of the proposed West
Office Tower planned for the northwest corner of the property. Furthermore, since retail tenant space is
planned for the perimeter of the proposed parking garage (southern portion of the property), four soil-
gas samples were collected from this area. The eight soil-gas sample locations are shown on Figure 1.
Wood proposed to install the two interior temporary sub-slab soil-gas sampling points through the
concrete floor slab of the existing office building (1100 S. Tryon Street) to a depth of about six inches
beneath the base of the slab. However, due to tenant occupation on the first floor of the office building,
installation of these sample points was not feasible.To expedite collection of additional soil-gas data
requested by the NCDEQ,DWM, BFP,Wood proposed that the two interior sample locations be moved to
the exterior of the building. Wood presented the proposed locations on an aerial photograph to the BFP
for approval.
Assessment Activities
On May 24, 2019,Wood personnel mobilized to the site and selected two locations (SG-9 and SG-10) to
install soil-gas sampling points.The soil-gas sampling locations are depicted on Figure 1.The sampling
locations were located within the proposed footprint of the East Office Tower planned for the eastern
property corner.
The soil-gas sampling was performed in general accordance with the NCDEQ, DWM Vapor Intrusion
Guidance, dated March 2018 (https://deq.nc.gov/about/divisions/waste-management/waste-
management-permit-guidance/dwm-vapor-intrusion-guidance).Soil borings for the two soil-gas
sampling points were advanced to approximately five feet below ground surface (bgs)by Wood personnel
using a stainless steel hand auger.The hand auger was decontaminated between boring locations using a
Liquinox®wash and distilled water rinse.The dedicated sampling points were placed in each borehole and
connected to Teflon™ tubing extending to the ground surface and attached to 6-liter Summa canisters. A
sand pack of approximately 8 to 10 inches thick was placed around each sampling point. The remaining
annulus of each borehole was filled with hydrated bentonite to the ground surface. Prior to sample
collection, each sample train was purged of stagnant air using a peristaltic pump and a leak-check was
performed. The Summa canisters and sample train were surrounded by a helium-shroud for leak-check
detection. The helium-shroud consisted of a plastic container placed over the Summa canister and sample
tubing,which was then filled with helium.Wood personnel used the helium detector to monitor the
concentration of helium inside the shroud.Wood collected each leak-test soil-gas sample using a Tedlar®
bag. The leak-test soil-gas sample was screened in the field for helium using a MGD-2002 Multi-Gas leak
(di-electric) detector. A leak was considered to have occurred when the helium concentration inside the
Tedlar®bag was greater than 10% of the helium concentration within the shroud. No leaks were detected
during the soil-gas sampling.

Following the leak-tests, a soil-gas sample was collected in a Summa canister from each sampling point at
an approximate flow rate of 200 mL/min (30-min sample time).The Summa canisters were shipped via
courier to Con-Test Analytical Laboratory (Con-Test)in East Longmeadow, Massachusetts for analysis of
VOCs via EPA Compendium Method TO-15.One field duplicate QA/QC soil-gas sample (Dup-1) was
collected from the sample point SG-10 for analysis by Method TO-15. Following the collection of the soil-
gas samples, the soil-gas points were removed and the boreholes were abandoned by filling with
bentonite to grade.Soil-gas sampling field worksheets for the two soil-gas samples are included in
Attachment A.
Results
A summary of the February and May 2019 soil-gas laboratory analysis is included in Table 1. The
laboratory analytical report and chain-of-custody form are included in Attachment B. The results are
summarized as follows:
The laboratory analysis of soil-gas samples SG-9 and SG-10 identified several VOC constituent
concentrations above their respective reporting limits.However, the concentrations identified did
not exceed their respective NCDEQ Non-Residential Soil-Gas Screening Levels (SGSLs).
Analysis of the February 2019 soil-gas samples identified a concentration of 1,3-Butadiene in soil-
gas sample SG-7 (area of proposed parking deck) that exceeded the Residential SGSL for 1,3-
Butadiene.However, the concentrations identified did not exceed their respective NCDEQ Non-
Residential SGSLs.
Analysis of the soil-gas samples SG-2 (area of proposed West Office Tower) and SG-9 (area of
proposed East Office Tower) identified concentrations of chloroform that exceeded the
Residential SGSL for chloroform.However, the concentrations identified did not exceed their
respective NCDEQ Non-Residential SGSLs.
Analysis of the July 2017 soil-gas samples (generally in the area of the proposed East Office
Tower)did not identify detectable concentrations of VOCs that exceeded either the Non-
Residential or Residential SGSLs.
Conclusions and Recommendations
The properties will soon be redeveloped for non-residential use. The results of the soil-gas sampling and
analysis performed between July 2017 and May 2019 did not identify soil-gas concentrations that
exceeded the Non-Residential SGSLs. The data suggest that the potential for vapor intrusion into the
buildings to be constructed at the site is low. For this reason, Wood does not recommend the design or
installation of vapor intrusion mitigation systems for these structures.

Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
J
Laboratory fortified blank /laboratory control sample recovery outside of control limits. Data validation is not
affected since all results are "not detected" for all samples in this batch for this compound and bias is on the high
side.
L-01
Continuing calibration verification (CCV) did not meet method specifications and was biased on the high side for
this compound.
V-06
Initial calibration verification (ICV) did not meet method specifications and was biased on the high side. Data
validation is not affected since sample result was "not detected" for this compound.
V-36
Compound fails the method requirement of 70-130% recovery for the LCS. Is classified by the lab as a difficult
compound and passes the in house limits of 50-150%.
