Indoor Air & Sub -Slab Vapor Sampling Report Revision 1.0
Seneca Place Brownfields Site
Charlotte, Mecklenburg County, North Carolina
Brownfields Project Number 18045-14-060
ECS Project No. 49:11814-A
December 9, 2020
1.0 INTRODUCTION
The subject property is located at 5033 South Boulevard in Charlotte, Mecklenburg County, North Carolina
(Figures 1 and 2) and identified by the Mecklenburg County GIS as Parcel Identification Number (PIN)
17105209. The site currently consists of an approximate 36,750-square foot multi -tenant strip shopping
center that was constructed in 1985, an approximate 5,700-square foot automotive garage that was
constructed in 1984, associated parking areas, and various landscaped areas. Due to previously identified
groundwater and associated vapor contaminants at the site, the site was included into the North Carolina
Department of Environmental Quality (NCDEQ), Brownfields Program (BP). The Brownfields Agreement
(BFA) for the site was finalized in April 2016. The Brownfields Project number for the site is 18045-14-60.
The entity, Seneca Place Partners, LLC, intended to conduct plumbing up -fits in Suites A and B of the strip
shopping center. Suite A is approximately 5,500 square feet (sq/ft) and Suite B is approximately 5,000
sq/ft. The two suites have been combined into one unit that is utilized as a CrossFit gym. In accordance
with the BFA, the NCDEQ, BP was notified of the intended up -fits and the NCDEQ, BP required that a new
Environmental Management Plan (EMP) be prepared to address the proposed activities. ECS completed
and submitted the EMP (ECS Project No. 49:11814) on July 9, 2020. The new EMP was approved by the
NCDEQ, BP on July 10, 2020. The plumping up -fits were conducted between July 20 and 22, 2020.
2.0 SCOPE OF WORK
Between September 28 and 29, 2020, ECS collected eight indoor air samples and on September 29, 2020
collected eight sub -slab soil gas samples inside Suites A and B. General photographs of the site are
included in Appendix A. These samples include IV-1 through IV-8 (indoor air) and SV-1 through SV-8 (sub -
slab soil gas).
Indoor air and sub -slab soil gas sampling were conducted to confirm that vapor intrusion (VI) concerns do
not exist in the portions of the building that are to be occupied. The indoor air and sub -slab soil gas
sampling were conducted in general accordance with the North Carolina Division of Waste Management's
(NCDWM) Vapor Intrusion Guidance document (March 2018, Version 2) and Vapor Sampling Work Plan,
Revision 2.0 dated August 6, 2020 and approved by the NCDEQ, Brownfields on August 11, 2020.
2.1 Indoor Air SamDlin
Between September 28 and 29, 2020, eight indoor air samples (IV-1 through IV-8) were collected at the
site as shown at the locations shown on Figure 3. The locations were selected based on accessibility and
as proposed in the above referenced approved Work Plan. Prior to conducting the indoor air sampling,
ECS completed an Indoor Air Building Survey and Sampling Form that included information concerning
the building characteristics, noted potential indoor air contaminant sources, general meteorological
conditions, as well as other general observations and conditions that could potentially affect sampling and
sample results. Meteorological conditions throughout the sampling event are summarized in Table 1. A
copy of the survey and sampling form is included in Appendix B.
In order to minimize disturbance of the canisters, ECS locked the doors to Suites A and B after initiating
the sampling. All doors and windows remained closed during the sampling, with the exception of when

December 9, 2020
ECS left and returned to complete the sampling. The heating, ventilation, and air conditioning (HVAC) was
operating in its normal mode when samples were collected. As noted on the indoor air building survey,
potential VOC source(s) were observed in a back room of the Suite A, consisting of concrete paint and
sealer. Safety Data Sheets (SDSs) for the concrete paint and sealer are included in Appendix C.
The samples were collected using individually certified 6-liter (L) Summa canisters equipped with 24-hour
flow restrictors. The 24-hour flow restrictors were utilized instead of the 8-hour flow restrictors that were
specified and approved in the work plan, due to an error by the laboratory in shipping. The use of the 24-
hour flow restrictors is not anticipated to affect the sample collection or laboratory results. The samples
were collected by placing each Summa canister at a height of approximately 5 feet above the floor during
sampling. ECS documented the vacuum readings indicated on each canister at initiation and termination
of sampling. These readings are included in Table 2 and the field notes included as Appendix B. The
sample containers were labeled, placed into protective packaging material and shipped to Con -Test
Analytical Laboratory (Con -Test) in East Longmeadow, Massachusetts, to be analyzed for volatile organic
compounds (VOCs) by EPA Method TO-15. ECS maintained chain -of -custody (COC) procedures throughout
the sample collection and transportation process. ECS collected one duplicate indoor air sample for
laboratory analysis by EPA Method TO-15. Sample IV-DUP was a duplicate of indoor air sample IV-3 and
was collected jointly with indoor air sample IV-3 via a tee connection in the tubing.
Concurrent with the indoor air sampling, one exterior (ambient) upwind air sample (OV-1) was collected
for laboratory analysis by EPA Method TO-15. The approximate location of the exterior sample is
indicated on Figure 3.
2.2 Sub -Slab Soil Gas Samalin
On September 29, 2020, ECS collected eight sub -slab soil gas samples from newly installed sub -slab
monitoring points (SV-1 through SV-8) at the site as shown at the locations shown on Figure 3. The sub -
slab samples were collected by installing new VaporPin° with a new silicon sleeve through the existing
concrete slab and allowed to equilibrate for a minimum of 20 minutes, prior to leak testing. New
dedicated and disposable polyethylene tubing was then connected from the VaporPin° to a pre -evacuated
and pre -cleaned batch certified Summa canister.
Prior to collecting the soil gas samples, laboratory grade helium gas was used as a quality
assurance/control measure to confirm the integrity of the VaporPin® seal. A plastic container (with an
approximate volume of 18 quarts) used as a shroud was placed and sealed over the sampling point and
sampling train. The sampling tubing and tracer gas tubing were placed through the container wall via
rubber grommets and a shroud was placed over the sample point and sample train leading to the purge
valves and sample port. The container was flooded with helium via the hose placed through the container
wall. A Model MGD-2000 Multi -Gas Leak detector was connected to the probe tube and three calculated
purge volumes were purged with a syringe. The calculated purge volume included the sample train as
well as the plumbing of the monitoring point plumbing. Helium samples were collected with a syringe
into a tedlar bag, and readings recorded in field notes and provided as Table 3. Additionally, the
construction details of the permanent sub -slab soil gas sampling points are included on the sampling field
notes. A concentration of less than 10 percent of the helium concentration within the shroud was
considered acceptable. Photographs of the helium leak test set-up are included in Appendix A.

Following the helium leak test, sub -slab soil gas samples were collected using 1-liter Summa canisters at
an approximate flow rate of 0.2 L/minute over an approximate 5-minute period. ECS documented the
vacuum readings indicated on each canister at initiation and termination of sampling. These readings are
included in Table 4 and the field notes included as Appendix B. The sample containers were labeled,
placed into protective packaging material and shipped to Con -Test to be analyzed for VOCs by EPA Method
TO-15. ECS maintained COC procedures throughout the sample collection and transportation process. A
copy of the COC is included in Appendix D. ECS collected one duplicate sub -slab soil gas sample for
laboratory analysis by EPA Method TO-15. Sample SV-DUP was a duplicate of sub -slab soil gas sample SV-
1. Please note that the difference between the laboratory noted vacuum reading and the initial sample
vacuum reading was greater than 10 percent.
3.0 LABORATORY ANALYSES
A summary of the laboratory analytical data for indoor air samples is shown on Table 2. Review of the
laboratory analytical report indicated ethylbenzene, naphthalene, 1,2,4-trimethylbenzene, m&p-xylenes,
and o-xylenes at concentrations greater than their respective Non -Residential Vapor Intrusion Screening
Level (VISL) in one or more of the samples collected. The ambient air sample (OV-1) detected multiple
VOCs at concentrations greater than the laboratory method reporting limit, but less than their respective
Non -Residential VISLs. Based on the results, it appears that the samples collected in Suite A (IV-1 through
IV-4 and IV-DUP) contained the higher detected concentrations of VOCs, which is the suite where concrete
sealer was observed to be stored.
A summary of the laboratory analytical data for sub -slab soil gas samples is shown on Table 4. Review of
the laboratory analytical report indicated several compounds in each of the samples collected at
concentrations greater than the laboratory method reporting limit, but less than their respective Non -
Residential VISLs.
The laboratory analytical report is included as Appendix D.
4.0 QA/QC
The Summa canisters were individually certified for indoor air samples and batch certified for the soil gas
samples. Helium concentrations did not exceed five percent (5%) helium above the shroud concentrations
during leak tests for sub -slab samples. During the sampling of sub -slab soil gas, the sample train was
closed when the canister vacuum decreased to approximately four to five inches of mercury (in-Hg). ECS
documented the vacuum readings indicated on each canister at initiation and termination of sampling.
These readings are included in Tables 2 and 4 and the field notes included as Appendix B. A duplicate
indoor air sample (IV-DUP) was collected in conjunction with IV-3 while a duplicate sub -slab soil gas
sample (SV-DUP) was collected from SV-1. Results of the duplicate analysis appear consistent with the
samples they were collected in conjunction with.

5.0 CONCLUSIONS AND RECOMENDATIONS
Based on the laboratory analytical data, petroleum -related VOCs were detected in the indoor air of the
portions of the building that were sampled above their respective Non -Residential VISLs. VOCs were not
detected in the sub -slab soil gas samples at levels exceeding their respective Non -Residential VISLs.
The absence of VOCs at concentrations above the Non -Residential VISLs in the sub -slab soil gas samples
suggest that the exceedances of VOCs in indoor air samples may be the result of a source or sources other
than vapor intrusion of soil gas. Additionally, it appears that the observed concrete paint and sealer in
Suite A may be a potential source of the detected VOCs. According to the SDSs, the compounds present
in the indoor air samples are listed as ingredients in the products seen. In addition, although ECS was
unaware at the time of the sampling, the products were used in Suites A and B the weekend before the
sampling was conducted. The initial driver for the sampling was a concentration of tetrachloroethene
detected in soil gas sample VMP-2 collected by Hart & Hickman on May 5, 2015. The locations of the
historic soil gas samples are shown on Figure 3 and the analytical results of the soil gas samples are
included in Appendix E. As such, the indoor air concentrations leading to the Non -Residential VISL
exceedances appear to be attributed to indoor air sources/materials used during construction and not a
result of vapors below the building.

Section 4. First aid measures
Description of necessary
first aid measures
Eye contact
Immediately flush eyes with plenty of water, occasionally lifting the upper and lower
eyelids. Check for and remove any contact lenses. Continue to rinse for at least 10
minutes. Get medical attention.
Inhalation
Remove victim to fresh air and keep at rest in a position comfortable for breathing. If it
is suspected that fumes are still present, the rescuer should wear an appropriate mask
or self-contained breathing apparatus. If not breathing, if breathing is irregular or if
respiratory arrest occurs, provide artificial respiration or oxygen by trained personnel. It
may be dangerous to the person providing aid to give mouth-to-mouth resuscitation.
Get medical attention. If necessary, call a poison center or physician. If unconscious,
place in recovery position and get medical attention immediately. Maintain an open
airway. Loosen tight clothing such as a collar, tie, belt or waistband. In case of
inhalation of decomposition products in a fire, symptoms may be delayed. The exposed
person may need to be kept under medical surveillance for 48 hours.
Skin contact
Flush contaminated skin with plenty of water. Remove contaminated clothing and
shoes. Continue to rinse for at least 10 minutes. Get medical attention. Wash clothing
before reuse. Clean shoes thoroughly before reuse.
Ingestion
Get medical attention immediately. Call a poison center or physician. Wash out mouth
with water. Remove dentures if any. Remove victim to fresh air and keep at rest in a
position comfortable for breathing. If material has been swallowed and the exposed
person is conscious, give small quantities of water to drink. Stop if the exposed person
feels sick as vomiting may be dangerous. Aspiration hazard if swallowed. Can enter
lungs and cause damage. Do not induce vomiting. If vomiting occurs, the head should
be kept low so that vomit does not enter the lungs. Never give anything by mouth to an
unconscious person. If unconscious, place in recovery position and get medical
attention immediately. Maintain an open airway. Loosen tight clothing such as a collar,
tie, belt or waistband.

Appropriate engineering
Use only with adequate ventilation. Use process enclosures, local exhaust ventilation or
controls
other engineering controls to keep worker exposure to airborne contaminants below any
recommended or statutory limits. The engineering controls also need to keep gas,
vapor or dust concentrations below any lower explosive limits. Use explosion -proof
ventilation equipment.
Environmental exposure
Emissions from ventilation or work process equipment should be checked to ensure
controls
they comply with the requirements of environmental protection legislation. In some
cases, fume scrubbers, filters or engineering modifications to the process equipment
will be necessary to reduce emissions to acceptable levels.
Individual protection measures
Hygiene measures
Wash hands, forearms and face thoroughly after handling chemical products, before
eating, smoking and using the lavatory and at the end of the working period.
Appropriate techniques should be used to remove potentially contaminated clothing.
Wash contaminated clothing before reusing. Ensure that eyewash stations and safety
showers are close to the workstation location.
Eye/face protection
Safety eyewear complying with an approved standard should be used when a risk
assessment indicates this is necessary to avoid exposure to liquid splashes, mists,
gases or dusts. If contact is possible, the following protection should be worn, unless
the assessment indicates a higher degree of protection: chemical splash goggles.
Skin protection
Hand protection
Chemical -resistant, impervious gloves complying with an approved standard should be
worn at all times when handling chemical products if a risk assessment indicates this is
necessary. Considering the parameters specified by the glove manufacturer, check
during use that the gloves are still retaining their protective properties. It should be
noted that the time to breakthrough for any glove material may be different for different
glove manufacturers. In the case of mixtures, consisting of several substances, the
protection time of the gloves cannot be accurately estimated.

Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the
calculation which have not been rounded.
J Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
L-05 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.
R-01 Duplicate RPD is outside of control limits. Reduced precision is anticipated for reported result.
V-05 Continuing calibration verification (CCV) did not meet method specifications and was biased on the low side for
this compound.
V-34 Initial calibration verification (ICV) did not meet method specifications and was biased on the low side for this
compound. Reported result is estimated.
