Post Occupancy VIMS Inspections & Annual Sampling Report Aberfoyle Village 18 Linestowe Drive Belmont, North Carolina DEQ Brownfields Project No.: 20094-16-036 H&H Job ABV-001 1.0 Introduction
On behalf of the Aberfoyle Village Homeowner’s Association (HOA), Hart & Hickman, PC
(H&H) has prepared this report to summarize post occupancy semi-annual VIMS inspections and
annual sub-slab soil gas sampling activities conducted at Aberfoyle Village located at 18
Linestowe Drive in Belmont, Gaston County, North Carolina. Aberfoyle Village is located on
the Former Belmont Dyers Brownfield Site (Brownfields Project No. 20094-16-036). The Site
consists of fourteen townhouse buildings (identified as Building 1 through Building 14) with
four to six individually owned units per building. As part of the development project, four of the
fourteen townhouse buildings (Building 4 through Building 7) were constructed with vapor
intrusion mitigation systems (VIMS) to reduce the potential for vapor intrusion from site
contaminants. The VIMS at Buildings 4 through 7 were installed in accordance with the DEQ
approved Vapor Intrusion Mitigation Plan – Revision 1 dated March 19, 2018 (VIMP) and the
Request for VIMP Modification – Revision 2 (VIMP Modification) dated April 14, 2020. In
addition, the developer pre-emptively installed a passive ventilation system in two townhouse
buildings (Building 8 and Building 9), although a VIMS in these townhome buildings were not
required in the VIMP. Previous sub-slab soil gas results for Buildings 8 and 9 are detailed in the
Sub-Slab Vapor Assessment – Revision 1 report dated April 16, 2020 for these buildings. The
locations of the site buildings are depicted on the site map attached as Figure 1 and addresses and
unit numbers for Buildings 4 through 9 are presented in Table 1.

In accordance with the VIMP and VIMP Modification, semi-annual inspections of the passive
VIMS were conducted for Building 4 through Building 7 in September 2020 and March 2021,
and annual sub-slab soil gas sampling at these buildings were conducted in March 2021.
Although not required per the VIMP, as an additional conservative measure, semi-annual
inspections of the passive VIMS at Buildings 8 and 9 were also performed. A summary of semi-

annual inspection activities, annual sub-slab soil gas sampling activities, analytical results, and
conclusions are provided in the following sections.

2.0 Semi-Annual VIMS Inspections

H&H has completed two semi-annual VIMS inspection events for units at Buildings 4 through 9
on September 22, 2020 and March 4, 2021. The inspections for the passive VIMS inspections
included the following components 1) visual inspection of the exterior concrete perimeter footers
and available interior garage slabs for the presence of cracks, repairs, or other damage, and 2)
visual inspection of the wind-turbine ventilator fan and discharge pipes located above the
roofline. Note for Buildings 8 and 9, a wind ventilator fan is not installed, but the vent discharge
pipe was visually inspected.
During the September 2020 inspection, minor cracks in the garage foundation were observed at
townhome addresses 112, 224, 236, and 240 Linestowe Drive. Two of these units, 112 and 224
Linestowe Drive, contained garages that are attached to the main townhome living space. In
these units, inspections of the garage slabs indicated the minor hairline cricks were observed to
be generally confined to the exterior footer and did not propagate throughout the interior of the
garage slab. The wind turbine ventilator fans for Buildings 4 through 9 were all in good working
condition, and the discharge pipes at Buildings 8 and 9 were also in good condition.

During the March 2021 inspections, minor hairline cracks were observed at townhome addresses
100, 112, 136, 152, and 224 Linestowe Drive along the exterior foundations of the unit garages.
A crack was observed at 200 Linestowe Drive between the brick patio and the exterior concrete
footer along the garage at this unit. However, the crack was not observed to propagate to the
building concrete slab within the interior of the unit. Similar to the September 2020 inspection,
the wind-turbine fans for Buildings 4 through 9 were all in good working condition, and the
discharge pipes at Buildings 8 and 9 were also in good condition.

The foundation conditions observed during both inspection events seem to have little to no effect
on the efficacy of the underlying VIMS or passive ventilation system due to either the size of the

crack (hairline cracks) or the location of the crack (exterior perimeter footers). Furthermore, the
ventilator fans and and vent discharge pipes were in good condition. Therefore, based on the
observations, the passive VIMS at Buildings 4 through 7, and the passive ventilation system at
Buildings 8 and 9 seem to be operating as design. The observations made during each semi-
annual inspection were recorded in field forms attached as Appendix A.

3.0 Annual Sub-Slab Soil Gas Sampling
3.1 Annual Sub-Slab Soil Gas Sampling Activities
On March 4, 2021, H&H collected sub-slab soil gas samples from Buildings 4 through 7.
Samples were collected from the following monitoring points with the corresponding sample
identification number indicated in parentheses:

• Building 4 – MP-3 (SS-4-MP-3) and MP-6 (SS-4-MP-6)
• Building 5 – MP-3 (SS-5-MP-3), MP-5 (SS-5-MP-5), and MP-8 (SS-5-MP-8)
• Building 6 – MP-3 (SS-6-MP-3) and MP-6 (SS-6-MP-6)
• Building 7 – MP-3 (SS-7-MP-3) and MP-6 (SS-7-MP-6)

In addition, a duplicate sample, SS-4-MP-6-DUP, was collected from pressure measuring point
SS-4-MP-6 with the use of a laboratory-supplied “T-sampler” for quality assurance / quality
control (QA/QC) purposes. The specific locations of the monitoring points for each building are
depicted in the VIMS as-built drawings included as Appendix B.

The sub-slab samples were using recommended procedures presented in the DWM Vapor
Intrusion (VI) Guidance. Briefly, the samples were collected by emplacing a temporary
expandable plug with a sample port into the monitoring point to create an air-tight seal. Prior to
sample collection, a leak test was performed on each pressure measuring point by placing a
shroud around the sampling point, summa canister, and the sampling train. The air within the
shroud was saturated with helium gas, then soil gas was purged from the sampling point with a
GilAir vacuum pump into a Tedlar® bag. A helium gas detector was used to measure helium
concentrations in the shroud and bag. The leak test is considered successful if the helium

4
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Aberfoyle Village/VIMS Post Occupancy Report/2020-2021/Aberfoyle Village_VIMS Inspection and Annual Sampling Report_05192021.doc
concentration measured in the soil gas purged from the sampling point was less than 10% of the
concentration measured in the shroud. Results of the helium leak checks indicate that helium
was not detected above 10% of the shroud concentration in any of the samples, and thus the leak
test indicated a successful leak check.

Following the successful leak check, the sub-slab samples were collected into batch-certified 1.4-
liter stainless steel Summa canisters connected to airflow regulators preset by the laboratory to
collect the sample over an approximate 10-minute period. Vacuum inside the summa canisters
was recorded prior to and following the sampling period to ensure adequate sample volume was
collected at each sampling point. Upon completion of sample collection, the air flow regulators
were closed off to their respective Summa canisters. The canisters were labeled with the sample
identification, the beginning and ending times, the pressure measurements, and the requested
analysis. The ending pressure of each canister was approximately between -5 inches of mercury
(inHg) and -6 in Hg. The canisters were then placed in laboratory supplied shipping containers
and delivered to Waypoint Analytical (Waypoint) under standard chain of custody protocols for
analysis of volatile organic compounds (VOCs) by EPA Method TO-15.
3.2 Annual Sub-Slab Sampling Results

A tabular summary of the sub-slab soil gas analytical results is presented as Table 1 and
laboratory analytical reports and chain of custody record is provided as Appendix C.

The laboratory analytical results were compared to the DEQ DWM Residential Sub-Slab and
Exterior Soil Gas Screening Levels (SGSLs) dated January 2021. The results of the sub-slab
samples indicate that several VOCs were identified above the laboratory method detection limit
(MDL), but below the DEQ DWM Residential SGSLs. One compound, 1,2-dichloroethane, was
detected in sample SS-4-MP-6 and the duplicate sample at concentrations (9.37 ug/m3 and 9.26
ug/m3 respectively) above its Residential SGSL (3.6 ug/m3). No other analytes were detected at
concentrations exceeding their Residential SGSLs.

The DEQ DWM Vapor Intrusion SGSLs are conservative and are based on a target carcinogenic
risk (TCR) of 1 x 10-6 and a non-carcinogenic hazard quotient (HQ) of 0.2. DEQ’s acceptable

5
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Aberfoyle Village/VIMS Post Occupancy Report/2020-2021/Aberfoyle Village_VIMS Inspection and Annual Sampling Report_05192021.doc
risk level for potential carcinogenic risks is a cumulative lifetime incremental cancer risk (LICR)
of 1 x 10-4 or less and the acceptable level for non-carcinogenic risks is a cumulative hazard
index (HI) of 1.0 or less. The HI is the sum of the HQs for each detected target analyte.

H&H utilized the DEQ Risk Calculator (January 2021) to assess the potential for vapor intrusion
risks at unacceptable levels. As the Site is comprised of individual townhome units connected
together in townhouse buildings, H&H modeled a worst-case scenario for each building by using
the highest concentrations of any compound detected in the sub-slab samples for each building.
The risk calculations were compared to a residential use scenario. The calculated cumulative
LICRs and HI values for each building sampled are provided in Table 1, and a copy of the
completed DEQ Risk Calculators summary pages are provided as Appendix D.

As shown in Table 1, results of the worst-case risk calculations indicate that calculated LICRs
ranged from 1.4 x 10-8 to 2.6 x 10-6 and the calculated HIs ranged from 0.0099 to 0.063 across
Buildings 4 through 7. These values are orders of magnitude below the DEQ unacceptable risk
levels. The risk calculator results indicate that compound concentrations detected below the
townhouse slabs do not seem to pose vapor intrusion risks at unacceptable levels within the
townhouse buildings.

4.0 Summary
H&H has completed semi-annual VIMS inspections and annual sub-slab soil gas sampling at
Aberfoyle Village located at 18 Linestowe Drive in Belmont, Gaston County, North Carolina at
the Former Belmont Dyers Brownfield Site. The results of field activities undertaken are
summarized below:

• Two semi-annual VIMS inspections of the passive VIMS at Buildings 4 through 7 were
performed in September 2020 and March 2021, along with inspections for the passive
ventilation system at Buildings 8 and 9. Minor cracks in the exterior footers were
observed at a few of the townhouse units, but they seem to have little to no impact on the

efficacy of the underlying VIMS or passive ventilation system. All ventilator fans and
discharge pipes were operational and/or in good condition.
• An annual sub-slab soil gas sampling event was performed in March 2021 at Buildings 4
through 7. 1,2-Dichloroethane was detected at one sampling location in Building 4 at
concentrations in exceedance of the DEQ DWM Residential SGSL, but results of the
worst-case risk calculations indicate that calculated LICRs ranged from 1.4 x 10-8 to 2.6 x
10-6 and the calculated HIs ranged from 0.0099 to 0.063 across Buildings 4 through 7.
These values are orders of magnitude below the DEQ unacceptable risk levels.
• The risk calculator results indicate that compound concentrations detected below the
townhouse slabs do not seem to pose vapor intrusion risks at unacceptable levels within
the townhouse buildings.

In accordance with the VIMP Modification, one additional annual sub-slab soil gas sampling
event will be conducted in 2022. Furthermore, based on the results of the VIMS inspections and
the analytical results, H&H would like to request that the semi-annual VIMS inspections for
Buildings 4 through 7 be reduced to an annual frequency to coincide with the future annual sub-
slab soil gas sampling event. A post-occupancy VIMS inspection and sub-slab soil gas sampling
report summarizing these future field activities will be submitted for DEQ review following
completion of the 2022 sub-slab soil gas sampling event.
