Introduction

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. This project was
conducted on behalf of Benmar Properties, LLC, the current landowner.

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 currently occupied by Flat Rock Cabinet Shop.
The remaining approximately 107,000-square feet of the building is currently being used
for dry goods storage by International Express Trucking, Inc. At the time of this sampling
event, this portion of the building is not currently occupied by full-time employees.

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, PA 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
were installed and 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.

March 23, 2024 Sampling Event

On March 23, 2024 Harmon Environmental, PA collected 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 the North Carolina Department of
Environmental Quality in March 2018. This sampling event consisted of collecting 11

ambient barometric pressure and temperature were measured eight times during the testing
period (Table 1).

Indoor air sample A-4 was collected from Area 4 of the Danalex facility. This sample was
collected with Summa® Canister No. 42650 equipped with Flow Controller No. 17724
provided by Waypoint Analytical, LLC at the approximate location depicted on Figure 2.
The intake height of the canister was 58-inches above the floor. This test was initiated on
March 23, 2024 at 07:11 with an initial vacuum reading of 29 in Hg and terminated on
March 23, 2024 at 14:06 with a final vacuum reading of 9.5 in Hg. The ambient barometric
pressure and temperature were measured eight times during the testing period (Table 1).

Dear Rick Harmon:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 3/28/2024 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,
Angela D Overcash Senior Project Manager

2. * = If concentrations in groundwater exceed the NC 2L Standards or IMAC, or concentrations in surface water exceed the

** -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 of 0.15 J.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 of 0.15 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.

** -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 of 0.15 J.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.

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

** -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.
