Vapor Intrusion Evaluation 2205 and 2215 North Tryon Street Charlotte, North Carolina
H&H Job No. CLT-300

Dear Carolyn:

This vapor intrusion evaluation was conducted to facilitate Brownfield planning. The 2.86-acre
property consists of two buildings previously utilized as office and warehouse space. The
buildings are currently vacant. Ira Griffin and Sons occupied the subject facility between 1983
and 2008 where they fabricated, assembled, and shipped textile manufacturing equipment. Prior
to Ira Griffin & Sons, the property was utilized by Crawford Sprinkler System a trailer
manufacturer, and a neon sign manufacturer.

Step 1: Groundwater Screening
Groundwater data collected in 2008 at the Former Ira Griffin & Sons Property and the adjacent
Latimer property consisted of collecting six samples from temporary wells installed to a depth of
approximately 30 ft below ground surface (bgs). Each well was constructed of a 1-inch diameter
Schedule 40 PVC riser and a 15-ft length of 0.01-inch slot screen installed to bracket the water
table. Groundwater was encountered at depths ranging between 17 and 19 ft bgs. Following
depth-to-water measurement, each well was purged a minimum of one well volume using a
peristaltic pump and dedicated tubing, and the water quality parameters (pH, conductivity, and
temperature) were measured. After stabilization of the water quality parameters, ground water

samples were collected. All groundwater samples were analyzed for volatile organic compounds
(VOCs) by EPA Method 6230D and polycyclic aromatic hydrocarbons (PAHs) by EPA Method
8270C. The three groundwater samples collected August 2008 were also analyzed for metals by
EPA Method 6010B and 7470A/7471A. Following sampling, the temporary monitoring wells were
properly abandoned.

H&H compared the 2008 data with the current July 2012 IHSB Residential and
Industrial/Commercial Vapor Intrusion Screening Criteria. The 2008 groundwater data and
applicable screening criteria are shown on Table 1. A site map and sample location map are
included as Figures 1 and 2, respectively. The groundwater samples collected from TMW-3
(179 µg/L), TMW-5 (55.3 µg/L), and TW-4 (43.9 µg/L) contained 1,1-DCE at concentrations
exceeding the IHSB residential screening criteria. In addition, the concentration of 1,1-DCE
from TMW-3 exceeded the IHSB industrial/commercial screening criteria.

Step 2: Soil Vapor Assessment/Screening
In the April 15, 2009 letter, DENR requested submittal of a work plan and collection of soil gas
samples or subslab samples on the former Ira Griffin & Sons property and the adjacent Latimer
property to determine if soil vapor poses a potential unacceptable risk to current or future site
structures. H&H submitted a work plan for the soil vapor assessment on June 1, 2009.

The work plan was subsequently approved with comments by DENR on June 22, 2009, which
were incorporated into the sampling event. Two subsurface vapor points (VPs) labeled VP-3 and
VP-5 and one subslab VP labeled VP-4 were installed on July 16, 2009 on the former Ira Griffin
& Sons property. Sampling locations are depicted on Figure 2 and were installed on July 16,
2009 on the former Ira Griffin & Sons property. These locations corresponded with the
previously discussed groundwater sample points.

For the installation of VP-3 and VP-5, a hand auger was utilized to install a 3-inch diameter
boring through the underlying soil to a depth of 5 feet below land surface (bls). A rotary

hammer drill was utilized to bore through the concrete slab at the VP-4 location. The building
slab was observed to be approximately 6 inches thick at the VP-4 location and underlain by a
gravel layer.

A stainless steel AMS dedicated soil gas vapor point fitted with ¼-inch diameter Teflon tubing
was installed into each borehole. With the exception of VP-4, the tip installed at this subsurface
VP location was advanced to 5.5 feet bls. The tip installed at the VP-4 location was set
approximately 1 to 2 inches beneath the slab using an AMS Gas Vapor Probe Kit and slide
hammer. Filter sand was then poured through each borehole around the vapor point to
approximately 4 to 6 inches above each subsurface point and approximately 5 inches below the
top surface of the concrete slab at the VP-4 location. Each borehole was subsequently completed
by installing hydrated bentonite from the top of the sand to the surface of the borehole.

After allowing the bentonite to set for at least 24-hours in each borehole, H&H personnel
collected vapor samples from VP-3 through VP-5 on July 17, 2009 using 6-liter Summa
canisters. Prior to mobilizing to the site, the initial vacuum in each Summa canister was
measured and recorded using a vacuum gauge provided by the lab. In the field, the following
procedures were used to sample each VP. The VP was purged using a 60 mL syringe with a
three-way valve to evacuate air in the probe annular space and tubing. After purging the VP, the
Summa canister was connected to a flow regulator (set by the lab to limit the vapor intake rate to
approximately 6-liters per hour) and the sample train was checked for leaks. Subsequently, the
flow regulator was connected to the VP tubing using a ferrule to form an air-tight seal. The
canister’s air intake valve was then opened to begin collection of the vapor sample.

As approved by DENR in the June 2009 Work Plan, the samples were collected and analyzed for
1,2-DCA, cis-1,2-DCE, PCE, TCE, and vinyl chloride. However, the soil gas samples were not
required to be analyzed for 1,1-DCE at that time. Subsequently, H&H requested the lab reissue
the lab report to include 1,1-DCE. The lab report was revised and is included as Appendix A.
The available analytical results, compared against the IHSB Residential and

Industrial/Commercial Vapor Intrusion screening criteria are provided on Table 2. PCE was
detected in the samples from VP-4 and VP-5 at concentrations up to 50 µg/m3, which is below
both the residential and industrial screening criteria for PCE. In addition, 1,1-DCE was detected
in all three soil gas samples at concentrations up to 120 µg/mg3, which is below both the
residential and industrial screening criteria for 1,1-DCE.

Step 3: Indoor Air Sampling
This step was not completed as available soil gas concentrations were not detected above
applicable screening criteria.

Step 4: Recommendations
Based on the soil vapor results H&H does not recommend additional vapor intrusion assessment
or mitigation at the Ira Griffin & Sons Property.

LABORATORY NARRATIVEModified TO-15Hart & HickmanWorkorder# 0907610R1
Four 6 Liter Summa Canister samples were received on July 28, 2009. The laboratory performed
analysis via modified EPA Method TO-15 using GC/MS in the full scan mode.
This workorder was independently validated prior to submittal using 'USEPA National Functional
Guidelines' as generally applied to the analysis of volatile organic compounds in air. A rules-based,
logic driven, independent validation engine was employed to assess completeness, evaluate pass/fail of
relevant project quality control requirements and verification of all quantified amounts.
Method modifications taken to run these samples are summarized in the table below. Specific project
requirements may over-ride the ATL modifications.

Receiving Notes
Sample collection date was incomplete on the Chain of Custody (COC) for samples VP-4, VP-5 and
VP-5 (DUP). The sampling date was taken from the tags.
Tetrachloroethene in samples VP-5 and VP-5 (DUP) was outside of the 25% RPD crtieria for
