1.0 SITE DESCRIPTION
The Phase II construction area occupies the easternmost portion of a larger 5.82-acre site located
at 430 East 36th Street in Charlotte, North Carolina that is currently under construction as an
apartment complex (Phase I). Phase II, planned for development as commercial retail, is bound
to the north and south by railroad tracks, to the east by East 36th Street, and to the west by the
Phase I development area. Based on review of historical information, the eastern portion of the
site was developed as a fire extinguisher manufacturing company in the early 1900s. By the early
1930s, New England Waste Company occupied the site as a re-user of waste cotton products
provided from nearby textile mills. Newco Fibre, a textile-related company occupied the site from
the mid-1960s to the early 2000s. The portion of the building that formerly housed Newco Fibre
was demolished in 2014. Ultimate Gym and the Chop Shop, a concert venue, occupied the
remaining two on-site buildings from 2006 until the two former industrial warehouse buildings
were demolished and their slabs removed in January and February 2016. The most recently used
buildings on the site were located in the Phase I development area. Prior to demolition activities,
environmental assessment activities were conducted at the site to evaluate potential impacts from
historical operations on the site.
The site was accepted into the North Carolina Brownfields Program on May 1, 2015. Since
demolition activities ended in early 2016, initial redevelopment of the property (Phase I
Construction) included a first-floor retail level with residential areas above and adjacent to the
retail space. The mixed use building includes 344 apartment units encompassing 5 to 7 stories.
A portion of the development is partially below grade while the remaining portions of the structure
are being constructed on-grade. Redevelopment also includes a parking area to the east of the
building and a multi-level parking deck adjoining the building to the north. Two open courtyard
areas are located in the center of the main building. New access roads and pavement are being
constructed along the perimeter. The Environmental Management Plan (EMP) for the site is dated
February 15, 2016.
We understand that the Phase II development will include a one-story building with an
approximate 23,000 sq. ft. building footprint. The one-story building is anticipated to be a retail
building constructed on-grade.
Known contaminants identified at the site are discussed below.

Volatile Organic Compounds (VOCs)
Groundwater at the Brownfields Property was assessed in 2007 and 2015 but borings B-7 and B-
8 (2015) were the only groundwater sampling points located in the Phase II development area.
Reportedly, groundwater was not encountered in boring B-7 and no VOC constituents were
detected in the water sample from boring B-8. Groundwater was not encountered in borings SB-
6 and SB-13 during sampling activities conducted in 2007 within the Phase II development area.
In the Phase I development area, tetrachloroethylene was detected in a groundwater sample
obtained from boring B-1 at a concentration exceeding its NCAC 2L Groundwater Standard (2L
Standard). No other volatile organic compounds were detected exceeding their respective 2L
Standards at the Brownfields Property.
Semi-Volatile Organic Compounds (SVOCs)
Benzo(b)fluoranthene was detected at an estimated concentration slightly above its 2L Standard
in groundwater sample B-8 (located in the Phase II development area). No other SVOC
constituents were detected in the groundwater at the Brownfields Property exceeding their
respective 2L Standards.
Metals
Metals were detected in the groundwater at the Brownfields Property but metals typically do not
represent a vapor intrusion concern.
In addition to the potential on-site sources, the former Sinclair Refining Company and other
historical off-site businesses to the south (dry cleaning operations and gasoline stations) along
North Davidson Street were identified as recognized environmental conditions (RECs).
Planned redevelopment of the site under the NC Brownfields Program requires an evaluation of
soil vapor contaminant concentrations in areas of future development. This investigation was
designed to meet this requirement and was approved by Ms. Carolyn Minnich of the NC
Brownfields Program on June 27, 2017.
2.0 SCOPE OF SERVICES
Terracon’s Limited Site Investigation was performed in general accordance with Terracon’s
Proposal P71177E079 dated June 26, 2017. The scope of services included as depicted on Table
1:
§Installation of three soil vapor (SV) sample points;
§Collection of SV samples from the three SV sample points (including a duplicate sample);

3.0 FIELD INVESTIGATION METHODS
Terracon conducted the field work under a health and safety plan developed for this project. Work
was performed using United States Environmental Protection Agency (USEPA) Level D work
attire consisting of hard hats, safety glasses, protective gloves, and steel-toed boots.
3.1 Soil Vapor Sample Point Installation and Soil Sampling
Terracon submitted a request to the public utility locator [NC 811] to arrange for location of
underground public utilities from the street to the utility meter. Terracon also engaged Probe Utility
Locating, a private utility locating company, to locate on-site underground utilities in the specific
areas planned for drilling.
Technical approaches and methods outlined in this soil vapor investigation report are in general
accordance with the Interstate Technical and Regulatory Council’s Vapor Intrusion: A Practical
Guideline (2007) and Vapor Intrusion Pathway: Investigative Approaches for Typical Scenarios
(2007), as well as the NCDEQ DWM’s Vapor Intrusion Guidance (2014).
On July 12, 2017, three SV sampling points were installed at the site. Sample locations SV-01,
SV-02 and SV-03 were installed in the general vicinity of their proposed locations due to the
presence of construction equipment on the site. Sample locations are depicted on Figure 2. Each
SV sampling point was installed by a track-mounted AMS PowerProbe®direct push technology
drill rig using a 2-inch diameter soil sampler. The continuous soil core sampler was advanced to
10 feet below ground surface (bgs) and soils were screened in the field for volatile vapors using
a photo-ionization detector (PID). The scope of work included collection of one soil sample from
each boring with PID readings less than 10 ppm. Since PID readings were less than 10 ppm in
each boring, only one soil sample was collected from each boring for laboratory analysis by EPA
Method 8260 for volatile organic compounds (VOCs) and EPA Method 8270 for semi-volatile
organic compounds (SVOCs).
Soil lithology characterized from soils at the three boring locations consisted predominantly of a
mixture of red, brown, and tan clayey silt. Groundwater was not encountered in the three soil
borings. Soil samples were collected from approximately 2 to 4 feet bgs. Results are presented
on Table 2.
Following extraction of the soil core, a new 6-inch long stainless steel wire mesh soil gas screen
attached to Teflon tubing was inserted into each borehole to a depth of 10 feet below ground
surface. The annular space between the screen and the borehole wall was backfilled with No. 2
well filter pack sand to about 0.5 feet above the top of the screen. Hydrated bentonite grout was
then used to fill the borehole from the top of the sand pack to the ground surface. Each SV point
was temporarily protected at the surface by placing a traffic cone over the sample point. Sample
location SV-01 was located in an area of the site exposed to heavy traffic; thus, a 6-inch diameter

steel manhole cover was installed to protect the soil vapor sample point. The tubing from each
sample point was sealed at the top of the boring with a silicone cap. The sample points were
allowed to equilibrate for at least two hours prior to sampling.
3.2 Soil Vapor Sampling
Terracon collected the three SV samples on July 12, 2017. In order to test the integrity of the
sampling point seals, both a shut-in test and a helium tracer test were conducted at each sample
point. A Dielectric MGD-2000 helium detector was used to verify the presence and concentration
of the tracer gas (helium).
The protocol for using a tracer gas is to enclose the sample manifold, tubing, and ground interface
with a shroud and enrich the shroud atmosphere with helium. Prior to sample collection, the vapor
point annulus and attached Teflon® lined tubing and sample train were purged using a vacuum
canister. Purge samples were then screened for helium to assess the presence of leaks in the
well seal and fittings and with a PID to assess for VOCs. Sample collection was started if the
tracer testing indicated the helium concentration in the vapor point was less than 10 percent of
the helium concentration in the shroud, indicating an appropriately sealed vapor point annulus.
Samples were collected with 1.0-liter Summa® canisters equipped with 170 ml/min flow controllers
and analyzed for VOCs per EPA Method TO-15 (full reporting list). Additionally, one duplicate
sample was collected to assess laboratory method precision. The vacuum pressure of each
sample canister was monitored and recorded at regular intervals throughout the sampling period.
Soil vapor field sample records are included in Appendix A. After completion of soil vapor
sampling activities, the vapor sample points were capped and left in place. Details regarding
sample IDs and analytical methods for the SV samples are provided in Table 1.
Following completion of the field activities, the Summa canisters (four canisters/samples), along
with chain-of-custody documentation, were shipped to Contest Analytical Laboratory in East
Longmeadow, Massachusetts for laboratory analysis of volatile organic compounds (VOCs) by
EPA Method TO-15. Samples were submitted on a standard laboratory schedule.
3.3 Outdoor Air Sampling
One outdoor air (OA-01) sample was collected concurrently with the soil vapor samples to assess
the presence of VOCs in ambient air. The canister was located in such a way that it did not
interfere with the site activities and the sample intake was at breathing height (approximately 5
feet above ground surface).
Due to busy construction activities at the site, Terracon personnel determined that the best
location for the outdoor air sample canister was near a chain link fence located along the northern

property boundary in order to sample ambient air upwind of the site. The sample was collected
using a laboratory supplied 6-liter Summa canister attached to a flow controller set for 24 hours.
Following completion of the outdoor air sample field activities, the Summa canister (1
canister/sample), along with chain-of-custody documentation, was shipped to Contest Analytical
Laboratory in East Longmeadow, Massachusetts for laboratory analysis of volatile organic
compounds (VOCs) by Modified EPA Method TO-15-Low Level on a standard laboratory
schedule.
4.0 RESULTS
The laboratory analytical reports and chain-of-custody record are attached in Appendix B. The
following sections describe the results of the testing at Phase II.
4.1 Shut-In and Leak Test Results
No leaks were detected in the sample manifolds during the shut-in tests. After purging, the sample
tubing was screened for helium to evaluate the presence and severity of leaks. Helium was not
detected inside the tubing for samples SV-01, SV-02 and SV-03 during the leak tests.
4.2 Soil Sample Analytical Results
A soil sample was obtained from each boring at a depth of 2 to 4 feet bgs. Based on the analytical
results, acetone (0.0116J milligrams per kilogram [mg/kg]), methylene chloride (0.0044J mg/kg),
and naphthalene (0.0033J mg/kg) were detected in the soil sample from boring SV-1 located in
the northeastern portion of the site. The detected concentrations are estimated values that
exceed the method detection limit but are below laboratory reporting limits. None of the detected
constituents exceed the regulatory standards. No constituents of concern were detected in the
soil samples from borings SV-2 or SV-3. Results are presented in Table 2 and in the laboratory
analytical report (Pace) included in Appendix B.
4.3 Soil Vapor Sample Analytical Results
Laboratory analytical results for the soil vapor samples were compared to the NCDEQ Division of
Waste Management (DWM) Soil Gas Screening Levels (SGSLs) for residential and non-
residential exposure scenarios, updated October 2016. Results are presented in Table 3 and are
summarized below. The soil vapor laboratory analytical report is included in Appendix B.
§Exceeding Non-Residential SGSLs:
None of the VOC constituent concentrations in the soil vapor samples exceeded Non-
Residential SGSLs.
Soil Vapor Investigation Report – Phase II Construction
NoDa Textile Brownfields Site ■ Charlotte, NC
September 19, 2017 ■ Terracon Project No. 71157713A
Responsive ■Resourceful ■Reliable 7
§Exceeding Residential SGSLs:
o Ethylbenzene in sample SV-02 (680 µg/m3)
o m,p-Xylene in sample SV-02 (3,000 µg/m3)
o o-Xylene in in sample SV-02 (850 µg/m3)
§Duplicate sample results (collected at sample SV-03) are comparable to the results
reported for the primary sample and indicate adequate laboratory method precision.
Ethylbenzene, m,p-xylenes, and o-xylenes have historically (previous assessment reports) not
been detected above laboratory detection limits in on-site soil or groundwater samples collected
in the Phase II construction area. The July 2017 SV samples were collected at an approximate
depth of 10 feet bgs in each boring. It is our understanding that approximately five feet of soil is
expected to be removed in the Phase II construction area and replaced at the location of the
proposed commercial retail building as a result of the geotechnical evaluation.
4.4 Outdoor Air Analytical Sample Results
Laboratory analytical results for the outdoor air sample were compared to the DWM Indoor Air
and Crawlspace Screening Concentrations (IASLs) for residential and non-residential exposure
scenarios, updated October 2016. The values assuming a target carcinogenic risk of 1.0E-06 and
a target hazard quotient of 0.2 (i.e., the IASL(A) values on DWM’s screening tables) were used.
§Analysis of the outdoor/background air sample, OA-01, detected naphthalene at a
concentration of 1.4 µg/m3 which exceeds the residential and non-residential IASLs.
Laboratory results also detected various other VOCs at concentrations below the
residential and non-residential IASLs.
§The NCDEQ Cumulative risk factor calculator indicated that none of the samples
exceeded non-residential carcinogenic risk factors.
§The three compounds (ethylbenzene, m,p-xylenes and o-xylenes) detected in the soil
vapor samples above residential SGSLs were not detected in the outdoor air sample
above residential or non-residential IASLs.
Air sample results are summarized in Table 3. The laboratory analytical report is included in
Appendix B.
5.0 CONCLUSIONS AND RECOMMENDATIONS
The following conclusions are based on the scope of services described in this report and subject
to the limitations described herein.

§Analytical results of soil samples obtained from the three SV borings did not indicate any
VOC constituents above residential screening levels. Adjustments to the EMP regarding
soil management procedures in the Phase II construction area are not necessary.
§The three SV samples collected at the site in July 2017 did not contain VOC constituents
exceeding the non-residential SGSLs.
§Analytical results of sample SV-02 collected in the central portion of the Phase II
construction area detected ethylbenzene, m,p-xylenes and o-xylenes at concentrations
exceeding their respective residential SGSLs. The source for these compounds is
currently unknown. Prior Terracon assessment reports (dated March 30 and August 26,
2015) did not detect ethylbenzene, m,p-xylenes, and o-xylenes in soils or groundwater in
the Phase II construction area.
§The NCDEQ Cumulative risk factor calculator indicated that none of the samples
exceeded non-residential carcinogenic risk factors.
§The analytical results do not support the need for vapor mitigation measures in the Phase
II construction area which is planned for development as commercial retail.
§The ambient air sample contained naphthalene at a concentration above its non-
residential IASL. Constituents detected above residential SGSLs in soil vapor samples
were not detected in the outdoor air sample above residential or non-residential IASLs.
