Indoor Air Quality Sampling Results Report
Former Dana/ex Facility
515 E. Alabama Avenue
Gastonia, North Carolina
In January 2023, Harmon Environmental, PA and PGP Services, LLC initiated the
construction of a vapor mitigation system at the Former Danalex industrial/commercial
facility at 515 E. Alabama Avenue in Bessemer City, North Carolina. Figure 1 depicts the
location of the site on an excerpt of a United States Geologic Survey (USGS) topographic
map of the region. This system was constructed to address sub-slab soil contamination
resulting from historic uses of the property. Based on files maintained at the North Carolina
Department of Environmental Quality (NCDEQ) the property has historically been used
for textile manufacturing. In 1998 soil samples collected from beneath the floor slab in
Area 5 indicated the presence of chlorinated solvents.
The former Danalex building is approximately 125,000 square feet (Figure 2).
Approximately 18,000-square feet (labeled Area 2) is constructed with a crawlspace. This
portion of the facility operates independently of the remainder of the facility. Area 2 of
the facility is occupied by Flat Rock Cabinet Shop.
Prior to October 2023, the remaining approximately 1 07,000 square feet of the building
was being used for dry goods storage by Cherryville Bonded Warehouse. This portion of
the building was not occupied by full-time employees. During this period, Cherryville
Bonded Warehouse on-site storage included Chinese manufactured poly vinyl chloride
(PVC) Christmas ornaments. Logistic firms like Cherryville Bonded Warehouse are used
by suppliers as staging facilities for seasonal inventory. During the second quarter of2023
the volume of this inventory substantially increased in preparation for the 2023 Christmas
season.
The vapor mitigation system was designed and constructed to address historic sub-slab soil
contamination documented beneath Area 5 of the on-site structure. Based on pilot test
results, Harmon Environmental, P A and PGP Services, LLC installed a mitigation system
consisting of 28 vapor extraction points (Figure 2). This system was designed to operate
continuously. In addition to the continuously operating the sub-slab vapor extraction
system, multiple ventilation fans within the building and exhaust fans on the exterior walls
and roof of the building were scheduled to operate continuously.
To monitor the system's effectiveness, Harmon Environmental, PA personnel installed 10
Vapor Pin™ permanent sub-slab vapor sample points through the floor of Area 5 (Figure
2). These sample points were constructed with stainless-steel Vapor Pins™ and stainless-

steel protective covers.
Following system construction, on April 12, 2023 Harmon Environmental, PA initiated a
quarterly indoor air sampling program to monitor the effectiveness of the mitigation system
at the facility. The indoor air sampling program ini~ially consisted of collecting eleven
indoor air samples and one background out-door sample from the site. These samples were
collected from Areas 1, 3, 4, 5 and 6 of the Benmar Properties, LLC facility. As previously
discussed, Area 2 is constructed over a crawlspace and not susceptible to the sub-slab
conditions observed in Area 5 of the facility.
The April 12, 2023 indoor sampling event was performed in general accordance with the
Vapor Intrusion Guidance (Version 2) published by the North Carolina Department of
Environmental Quality in March 2018. This sampling event consisted of collecting 11
indoor and one upwind outdoor sample using Summa® canisters. Following completion
of the sampling activities, the canisters were returned to the Waypoint Analytical
laboratory in Charlotte, North Carolina for analysis.
The results of this samples were analyzed using the North Carolina Department of
Environmental Quality (NCDEQ) Risk Based Calculator and did not exceed the NCDEQ
threshold for carcinogenic risk of 0.0001 and/or a hazard index threshold of 1 for non­
residential use.
July 2023 Sampling Event
On July 25, 2023 Harmon Environmental, PA collected a second round of quarterly indoor
air samples at the Benmar Properties, LLC facility. This event was performed in general
accordance with the Vapor Intrusion Guidance (Version 2) published by theN orth Carolina
Department of Environmental Quality in March 2018. This sampling event consisted of
collecting 11 indoor and one upwind outdoor sample using Summa® canisters. Following
completion of the sampling activities,. the canisters were returned to the Waypoint
Analytical laboratory in Charlotte North Carolina for analysis.
Upon arrival at the site for the July 25, 2023 sampling event, Harmon Environmental, PA
discovered a substantial increase to the volume of Cherryville Bonded Warehouse freight
in the building. Further, the building was completely closed with many of the air
circulation fans turned off. Further, five of the 28 sub-slab mitigation fans were not
functioning properly.
Air sample 897Al was collected from the fence near the northeastern property line ofthe
former Danalex structure with Summa® Canister No. 36101 and Flow Controller No.
13120 provided by Waypoint Analytical. The intake height of the sampler was 64-inches
above the ground. This test was initiated on July 25, 2023 at 08:01 with an initial vacuum
measurement of28.5 inches of Mercury (in Hg) and terminated at 16:05 on July 25, 2023
with a final vacuum measurement of 7 in Hg. The ambient barometric pressure and

Cherryville Bonded Warehouse was storing dry goods in the building at this time. The
building was not occupied by full-time employees.
Data Evaluation and Recommendations
Review of data associated with both these sampling events indicated the presence of 1 ,2-
dichloroethane in many of the indoor air samples from both the July and August 2023
sampling events. 1 ,2-Dichloroethane was not detected in sub-slab soil samples collected
from the facility. 1,2-Dichloroethane was detected in only one sub-slab vapor sample
collected from the southeastern portion of Area 5 at the facility at a concentration of 26.3
micrograms per cubic meter (!lg1M3). As a result, the prevalence of this compound
throughout the indoor air samples was suspected to be the result of a source other than the
impacted soil beneath the floor slab.
Investigations indicate that 1,2-dichloroethane is a degradation product of polyvinyl
chloride (PVC). Further, literature indicates that PVC is a primary component in the
manufacturing of Christmas Ornaments originating in China. At the time of these sampling
events, Cherryville Bonded Warehouse was storing a large volume of Chinese
manufactured PVC Christmas ornaments at the subject site.
Harmon Environmental, P A utilized the Risk Calculator to re-evaluate the August 22, 2023
analytical results excluding the 1 ,2-dichloroethane data. Removal of the 1,2-
dichloroethane concentrations from the calculator data changed the combined results
resulting in nine of the eleven samples not exceeding the non-residential standards.
Following review of these data Benmar Properties, LLC, the property owner, requested
Cherryville Bonded Warehouse remove these dry goods from the facility. These stored
goods were removed from the site prior to October 1, 2023.

Based on these results, PGP Services, LLC was retained to replace the three wall fans in
Area 5 and install an additional fan in Area 1 and Area 4. These fans are scheduled to be
installed in October 2023. Further, as noted above, Harmon Environmental, P A to retained
to visit the facility monthly to inspect and maintain the sub-slab mitigation system. As of
the October inspection report, the mitigation system was operated as designed. Following
the sub-slab mitigation system repair work and the installation ofthe fans described above,
Harmon Environmental, PAis scheduled to resample the indoor air at the facility. Until
analytical results indicate the indoor air concentrations are below the non-residential
standards, full time occupancy of the building should not be allowed.

Dear Rick Harmon :
449 Springbrook Rd, Charlotte, NC 28217
Main 704.529.6364
www.waypointanalytical.com
Waypoint Analytical, LLC (Charlotte) received sample(s) on 8/24/2023 for the analyses presented in the
following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method.
The analytical data has been validated using standard quality control measures performed as required by the
analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136
Method Update Rule May 2021) unless otherwise indicated .
Certain parameters (chlorine, pH , dissolved oxygen , sulfite ... ) are required to be analyzed within 15 minutes of
sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time.
Refer to sample analysis time for confirmation of holding time compliance. ·
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as­
received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to
the samples included in this report.
Please do not hesitate to contact me or client services if you have any questions or need additional information.
Sincerely, v
Angela D Overcash

** -Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate carcinogenic risk
or hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard of0.15 11g/m3.
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Risks are calculated for these values if indoor
air concentrations are entered and indoor air screening levels have been established, but it should be noted that detections of these chemicals are likely not
associated with vapor intrusion.

** -Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate carcinogenic risk
or hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard ofO. 15 )lg/m3.
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Risks are calculated for these values if indoor
air concentrations are entered and indoor air screening levels have been established, but it should be noted that detections of these chemicals are likely not
associated with vapor intrusion.

**-Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate carcinogenic risk
or hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard of0.15 Jlg/m3•
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Risks are calculated for these values if indoor
air concentrations are entered and indoor air screening levels have been established, but it should be noted that detections of these chemicals are likely not
associated with vapor intrusion.

Notes:
1. Iflead concentrations were entered in the exposure point concentration tables, see the individual calculator sheets for lead
concentrations in comparison to screening levels. Note that lead is not included in cumulative risk calculations.
2. * = If concentrations in groundwater exceed the NC 2L Standards or IMAC, or concentrations in surface water exceed the
NC 2B Standards, appropriate remediation and/or institutional control measures will be necessary to be eligible for a risk-based
closure.
3. NM =Not modeled, user did not check this pathway as complete.
4. NC = Pathway not calculated, required contaminant migration parameters were not entered.

** -Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate carcinogenic risk
or hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard of0.15 J.!g/m3.
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Risks are calculated for these values if indoor
air concentrations are entered and indoor air screening levels have been established, but it should be noted that detections of these chemicals are likely not
associated with vapor intrusion.
All concentrations are in ug/m3
