Limited Phase II ESA Report United Air Filter Company
1000 West Palmer Street Charlotte, North Carolina H&H Job No. UAF-001
1.0 Introduction and Background
On behalf of United Air Filter Company (UAF), Hart & Hickman, PC (H&H) has prepared this
Limited Phase II Environmental Site Assessment (ESA) Report to document assessment
activities conducted at the UAF property located at 1000 West Palmer Street in Charlotte,
Mecklenburg County, North Carolina (Site or subject Site). A Site location map is provided as
Figure 1.
The subject Site is comprised of one contiguous parcel (Mecklenburg County Parcel ID
No. [PIN] 07325204) that totals approximately 2.13 acres of land. The Site is developed with an
approximately 44,520-square foot (sq ft) commercial warehouse building that was constructed in
1920. The Site is currently owned and occupied by UAF, which utilizes the Site for the
production and distribution of air filters for commercial and/or residential use. Remaining
portions of the Site consists of vacant, vegetated land and paved parking areas. A Site map is
provided as Figure 2.
A summary of Site background information and previous assessment activities conducted at the
Site is included below.
1.1 Site Background Information
The Site primarily consisted of undeveloped land prior to the construction of the existing
commercial warehouse building in 1920. In the 1920s, the building was initially operated as a
cotton storage warehouse for the McClaren Rubber facility formerly located southwest of the
Site. By the 1950s, the Site was occupied by the Gittlin Bag Company and the warehouse
building was utilized as a burlap bag cleaning facility. In 1968, UAF occupied the Site and later
2
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/United Air Filter/Phase II/Draft to Client/Limited Phase II ESA Report_UAF.doc
purchased the property in 1973 from the Gittlin Bag Company. Since 1968, UAF operations at
the Site have primarily included the fabrication, storage, and distribution of air filter products.

1.2 Previous Assessment Activities
In May 2022, Terracon Consultants (Terracon) conducted a Phase I ESA at the Site. In summary,
the Phase I ESA conducted by Terracon identified the following recognized environmental
conditions (RECs) in connection with the property:

• The long-term (100 plus years) industrial/commercial operation at the Site and
surrounding properties;
• Documented off-site groundwater impacts found at the adjacent upgradient Clarkson
Street Brownfields project; and
• Documented off-site groundwater impacts associated with the upgradient Worth Keeter
facility at 1117 South Clarkson Avenue.

To further evaluate the identified RECs, Terracon conducted a Limited Site Investigation (LSI)
at the Site in June 2022. Terracon’s LSI included the installation of three temporary monitoring
wells (TW-1, TW-2, and TW-3) and the collection of groundwater samples for laboratory
analysis of volatile organic compounds (VOCs), semi-VOCs (SVOCs), and Resource
Conservation Recovery Act (RCRA) metals. Locations of the temporary monitoring wells
installed by Terracon are shown on Figure 2.

Laboratory analytical results of the groundwater samples collected by Terracon indicated the
presence of trichloroethylene (TCE) in TW-2 (3.4 µg/L) above the North Carolina 2L
Groundwater Standard (2L Standard) of 3.0 µg/L. TCE was also detected in TW-1 (0.75 µg/L)
and TW-3 (0.48 J µg/L) but at concentrations below the 2L Standard. In addition to TCE,
multiple metal concentrations were detected above their respective 2L Standards in the
groundwater samples collected. However, Terracon noted that the elevated metal concentrations
were likely due to high turbidity observed during groundwater sampling. Based on the results of
the LSI, Terracon concluded that the elevated concentrations of TCE detected in groundwater are
3
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/United Air Filter/Phase II/Draft to Client/Limited Phase II ESA Report_UAF.doc
likely attributable to off-site sources. A summary of previous groundwater analytical data is
provided in Appendix A.

To assist in the management of environmental concerns, the Site applied for eligibility into the
North Carolina Department of Environmental Quality (DEQ) Brownfields Program via the
Ready-for-Reuse Redevelopment Now track as a part of anticipated property transaction due
diligence activities. A Brownfields Property Application was submitted to DEQ on
November 16, 2022 for review and eligibility determination. A Letter of Eligibility was provided
by the Brownfields Program for the Site on May, 24, 2023.

In an effort to expedite the Brownfields process and due to time constraints associated with
potential future property transactions. H&H conducted a Limited Phase II ESA at the Site. The
Limited Phase II ESA activities described herein were designed and implemented to be
consistent with additional assessment activities typically requested by the DEQ Brownfields
Program as part of the Brownfields process. A description of our assessment activities and
results is provided in the following Sections.

2.0 Limited Phase II ESA Assessment Activities

In April 2023, H&H conducted Limited Phase II ESA activities at the Site. The Limited Phase II
assessment activities included collection of soil, sub-slab soil gas, and exterior soil gas samples.
In addition, H&H performed a receptor survey to obtain information about land use, water
supply, basements, underground utilities, drains, and surface water bodies at and in the vicinity
of the Site.

Prior to conducting field activities, H&H contacted North Carolina 811, the public utility locator,
to mark subsurface utilities at the Site. H&H also contracted with a private utility locator to mark
utilities which were not identified by the public locator. The private utility locator also utilized
ground penetrating radar (GPR) survey techniques to identify and mark utilities. In addition,
H&H directed the drilling contractor to hand clear each boring to a depth of approximately 5 ft
below ground surface (bgs) to further screen the boring locations for the presence of subsurface
utilities.

The assessment activities described herein were performed in general accordance with the DEQ
Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup of
Contaminated Sites (Guidelines) dated September 2022, the DEQ Division of Waste
Management (DWM) Vapor Intrusion Guidance (VI Guidance) dated March 2018, and the most
recent versions of the U.S. Environmental Protection Agency (EPA) Region IV Laboratory
Services and Applied Science Division (LSASD) guidance.

A summary of receptor survey results is provided in Section 3.0, a description of the soil
sampling and results is provided in Section 4.0, and a description of the sub-slab and exterior soil
gas sampling and results is provided in Section 5.0. Quality assurance and quality control
(QA/QC) measures implemented during the assessment activities and laboratory analysis are
provided in Section 6.0, and a summary and conclusions based on the results of the assessment
activities are provided in Section 7.0.

3.0 Receptor Survey

On April 18, 2023, H&H conducted a receptor survey at the Site and in the surrounding area.
Receptor survey activities included a pedestrian and vehicular survey for possible potable water
supply wells, springs, and surface water intakes within a 1,500 ft radius of the Site. H&H also
reviewed the online Mecklenburg County Well Information System for potential wells in the
area within a 1,500 ft radius of the Site. In addition, H&H also utilized DEQ’s Division of Water
Resources Source Water Assessment Program (SWAP) geographic information system map to
identify potential public water supply wells located within a 1,500 ft radius of the Site.
Additionally, H&H identified the locations of main underground and aboveground utilities, and
land use and zoning in the area of the Site using available Mecklenburg County online resources.
A receptor survey map is provided as Figure 3, and a copy of the completed DEQ Brownfields
Property Receptor Survey form is provided as Appendix B. Results of the receptor survey
activities are summarized below.

Zoning
The Site and surrounding properties to the north, south, east, and west are zoned as General
Industrial (I-2). Properties to the northeast (beyond the adjacent parcels) are zoned Uptown
Mixed-Use District (UMUD) and properties to the northwest (beyond the adjacent parcels) are
primarily zoned as business use with some mixed use, office use, and industrial zoning. General
zoning information for the Site area is shown in Figure 3.

Municipal Water Availability
Municipal water supplied by the City of Charlotte is available to the Site and surrounding area.
H&H did not identify sources of public drinking water within 1,500 ft of the Site based on
review of the Mecklenburg County Well Information System maps, DEQ SWAP, and the Annual
Water Quality Report published by the City of Charlotte. The City of Charlotte obtains raw water
from Lake Norman and Mountain Island Lake which are located approximately nine miles
northwest of the Site at Mountain Island Lake’s closest point.

https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/United Air Filter/Phase II/Draft to Client/Limited Phase II ESA Report_UAF.doc
Water Supply Wells
H&H conducted a pedestrian and vehicular survey of properties within a 1,500 ft radius of the
Site to identify potential water supply wells. No water supply wells were identified within a
1,500 ft radius of the Site.

Surface Water Bodies
Irwin Creek is located approximately 450 ft northwest of the Site from its nearest point
(Figure 3) and flows to the southwest. Based on the DEQ Surface Water Classification system,
Irwin Creek is a Class C surface water body. A Class C surface water body is defined as “Waters
protected for uses such as aquatic life propagation, survival and maintenance of biological
integrity (including fishing and fish), wildlife, secondary contact recreation, and agriculture.
Secondary contact recreation means wading, boating, other uses not involving human body
contact with water, and activities involving human body contact with water where such activities
take place on an infrequent, unorganized, or incidental basis.” H&H did not observe surface
water features located at the Site.

Subsurface Utilities and Structures
H&H contacted North Carolina 811, the public utility locator, to mark subsurface utilities located
on the Site and H&H conducted a visual reconnaissance in the Site area to identify potential
subsurface structures within 100 ft of the subject Site. H&H observed evidence of subsurface
utilities including sanitary sewer, storm sewer, natural gas, and municipal water, adjacent to the
Site and nearby adjacent properties (Figure 3). Overhead electrical lines were observed along
West Palmer Street and Post Street. H&H did not observe structures with potential basements
within a 1,000 ft radius of the Site during the visual reconnaissance.

4.0 Soil Assessment Activities

In April 2023, H&H contracted Geologic Exploration, Inc. (GEX) to advance two (2) soil
borings within the existing Site building. In addition, H&H collected six (6) background soil
samples for laboratory analysis from three (3) shallow soil borings advanced in areas that
appeared undisturbed by historical Site operations. Locations of the soil borings are shown in
Figure 2 and a description of the soil sampling activities and results is provided in the following
sections.

4.1 Soil Sampling Activities
H&H and GEX advanced two (2) soil borings (SB-1 and SB-2) within the southern portion of the
existing Site building. The purpose of the soil samples was to evaluate for the presence of
potential impacts in the historical waste and waste processing areas at the Site (Figure 2). The
soil borings were advanced to a total depth of approximately 5 ft bgs using a decontaminated
stainless-steel hand auger. During boring advancement, soil was recovered from the hand auger
bucket; logged for lithological description; and field screened for the presence of staining, odors,
and the presence of organic vapors using a calibrated photoionization detector (PID). Field
screening did not indicate the obvious presence of significant soil impacts. Therefore, H&H
collected one soil sample from the SB-1 and SB-2 soil borings for laboratory analysis from the
0 to 2 ft bgs interval. Additionally, H&H collected one duplicate soil sample from the SB-1 soil
boring for QA/QC purposes. Soil boring logs with lithological descriptions and field screening
results are provided in Appendix C.

The soil samples were placed in dedicated laboratory-supplied sample containers and labeled
with the sample identification, date, and requested analysis, and placed in a laboratory-supplied
cooler with ice. The soil samples were submitted to Pace Analytical Services, LLC (Pace) under
standard chain-of-custody protocols for analysis of VOCs by EPA Method 8260, SVOCs by
EPA Method 8270, and RCRA metals plus hexavalent chromium by EPA Methods
6020/7471/7199.

https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/United Air Filter/Phase II/Draft to Client/Limited Phase II ESA Report_UAF.doc
Background Soil Sampling
In addition to the soil samples described above, H&H collected six (6) background soil samples
at the Site from three (3) borings (BG-1 through BG-3) to establish Site-specific background
levels of naturally occurring metals. The soil samples were collected from the northern portion of
the Site in areas that are unpaved and appeared to be undisturbed by historical Site use. Two (2)
samples were collected at each background location (0 to 2 ft bgs and 2 to 4 ft bgs). The samples
were submitted to Pace for laboratory analysis of RCRA metals plus hexavalent chromium by
EPA Methods 6020/7471/7199. Based on the results of the metals analysis (discussed in
Section 4.2), samples BG-1 (0-2), BG-1 (2-4), and BG-3 (0-2) were also analyzed for lead using
the Toxicity Characteristic Leaching Procedure (TCLP).

Following sampling activities, the soil borings were abandoned and the surfaces were repaired
similar to pre-drilling conditions. Additionally, the soil sample locations were estimated using a
hand-held global positioning system (GPS) unit.

4.2 Soil Sampling Analytical Results
A tabular summary of the soil sample analytical results is presented in Table 1, and the
laboratory analytical reports and chain of custody records are provided in Appendix D. The
laboratory analytical results were compared to the most recent version of the DEQ Residential
and Industrial/Commercial Preliminary Soil Remediation Goals (PSRGs) dated January 2023
and metals results were compared to published concentrations for naturally occurring metals in
North Carolina soil (Dragun and Chekiri; 2005) and Site-specific background levels. A
discussion of the laboratory analytical results in comparison to the screening levels and
background levels for metals is included below.

Laboratory analytical results of the soil samples did not indicate the presence of VOCs or
SVOCs above DEQ PSRGs. A low-level concentration of methylene chloride was detected in
sample SB-1 (0.112 C9 mg/kg) and duplicate sample SB-DUP (0.107 C9 mg/kg). The methylene
chloride concentrations are flagged by the laboratory as “C9” which indicates that the compound
is a common laboratory contaminant. Because the methylene chloride concentrations are low-
9
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/United Air Filter/Phase II/Draft to Client/Limited Phase II ESA Report_UAF.doc
level and flagged in the lab report as a common laboratory contaminant, the concentrations of
methylene chloride detected are not likely representative of Site conditions and are attributable to
laboratory contamination. No other VOC or SVOC compounds were detected at concentrations
above the laboratory method detection limits.

As expected, several metals were detected at concentrations above the laboratory method
detection limits in the soil samples due to the presence of naturally occurring background levels
of metals in soil. Arsenic was detected in each soil sample at a concentration above the DEQ
Residential PSRG of 0.68 mg/kg ranging in concentrations from 1.4 mg/kg (SB-DUP) to
1.6 mg/kg (SB-1 and SB-2). In addition, a concentration of hexavalent chromium was detected in
sample SB-1 (0.881 J mg/kg) and duplicate sample SB-DUP (0.398 J mg/kg) above the DEQ
Residential PSRG of 0.31 mg/kg. The arsenic and hexavalent chromium concentrations detected
are below their respective site-specific background mean and upper-range concentrations. As
such, the arsenic and hexavalent chromium concentrations detected are attributable to
background. No other metals were detected at concentrations above the DEQ PSRGs and site-
specific background levels.

Background Soil Sampling Results
As described in Section 4.1, background soil samples were collected for laboratory analysis from
areas that appeared not to have been impacted by historical Site operations. Concentrations of
arsenic, barium, cadmium, chromium, hexavalent chromium, lead, and mercury were detected in
the background samples above laboratory method detection limits. A summary of the laboratory
analytical results of the background samples is provided in Table 2.

Laboratory analytical results of the background samples generally aligned with available
published concentrations of naturally occurring background levels for North Carolina Soil
(Dragun and Chekiri; 2005) except for the concentration of lead detected in samples BG-1 (0-2)
(948 mg/kg), BG-1 (2-4) (237 mg/kg), and BG-3 (0-2) (346 mg/kg). The concentrations of lead
detected in these samples exceed the “Rule of 20” which could indicate potential leachable
concentrations greater than the toxicity characteristic hazardous waste level. The concentration
of lead in BG-1 (0-2) also exceeds the DEQ Industrial/Commercial PSRG of 800 mg/kg.
10
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/United Air Filter/Phase II/Draft to Client/Limited Phase II ESA Report_UAF.doc
To further evaluate the leachability of the lead concentrations in BG-1 (0-2), BG-1 (2-4), and
BG-3 (0-2), Toxicity Characteristic Leaching Procedure (TCLP) lead analysis was performed.
The laboratory analytical results of the TCLP analysis did not indicate the presence of lead above
the characteristically hazardous waste criteria. A summary of the TCLP analysis is provided in
Table 2.

As indicated above, laboratory analytical results of the background samples also indicated the
presence of hexavalent chromium above laboratory method detection limits. A published
naturally occurring background concentration for hexavalent chromium is not specified in the
reference material (Dragun and Chekiri; 2005). Hexavalent chromium can be associated with
anthropogenic activities but can also occur naturally in the environment. The concentrations of
hexavalent chromium detected in the background samples exceeded the Residential PSRG of
0.31 mg/kg and ranged from 0.621 J mg/kg [BG-3 (2-4)] to 5.11 mg/kg [BG-1 (0-2)].

The elevated concentrations of lead and hexavalent chromium in the background samples may be
attributable to surrounding property use and operations by Charlotte Pipe and Foundry and/or
former industrial operations in the Site area.

4.3 Soil Risk Evaluation

DEQ PSRGs are very conservative and based upon a Target Cancer Risk (TCR) of 1 x 10-6 for
potential carcinogenic effects and a Hazard Quotient (HQ) of 0.2 for potential non-carcinogenic
effects. Additional assessment or remediation is not typically warranted if the calculated
cumulative lifetime incremental carcinogenic risk (LICR) is 1 x 10-4 or less and the acceptable
level for non-carcinogenic risk is a calculated cumulative hazard index (HI) of 1.0 or less.

To further evaluate the cumulative exposure risks associated with the concentrations detected in
soil, H&H utilized the DEQ Risk Calculator (January 2023) under residential and non-residential
land use scenarios. To model the potential exposure risk under a hypothetical “worst-case”
scenario, H&H conservatively calculated the cumulative risks using the highest concentration of
any compound detected in any soil sample (including background samples) collected from the
11
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/United Air Filter/Phase II/Draft to Client/Limited Phase II ESA Report_UAF.doc
Site. Risk calculator results are summarized in the table below and a copy of the completed risk
calculators is provided in Appendix F.

Land Use Scenario Calculated

Cumulative HI
Calculated LICR or
HI Exceeds
Acceptable Risk
Levels?
Residential 2.2 x 10-5 0.31 No
Non-Residential 1.9 x 10-6 0.022 No

As indicated in the above table, the results of the risk calculation indicate that the calculated
cumulative risks do not exceed acceptable carcinogenic or noncarcinogenic risk levels for
residential and non-residential use exposure scenarios.

5.0 Vapor Intrusion Assessment Activities

To evaluate the potential for structural vapor intrusion, H&H installed and sampled four (4)
temporary exterior soil gas monitoring points and four (4) permanent sub-slab soil gas sampling
points within the footprint of the existing Site building. Locations of the exterior soil gas and
sub-slab soil gas sampling points are shown on Figure 2 and a description of the soil gas
sampling activities and results is provided in the following Sections.

5.1 Soil Gas Sampling Activities

Exterior Soil Gas Sample Point Installation
Under the direction of H&H, GEX advanced four (4) soil borings at the Site for the installation
of temporary exterior soil gas monitoring points SG-1 through SG-4. SG-1 and SG-2 were
installed in the northern portion of the Site in the vicinity of the previously identified elevated
TCE concentrations in groundwater, and SG-3 and SG-4 were installed in the southern portion of
the Site in the vicinity of the Site building.

The soil gas monitoring points were installed to a depth of approximately 5 to 7 ft bgs. The soil
borings were advanced using a decontaminated stainless-steel hand auger and direct-push
technology (DPT) drilling methods. During boring advancement, continuous soil samples were
collected and logged for lithologic description, observed for obvious evidence of staining and
unusual odors, and field screened for the presence of volatile organic vapors using a calibrated
PID. Field screening results did not indicate obvious evidence of potential impacts in the soil gas
monitoring point borings.

Once at target depth, a six-inch stainless steel vapor implant screen attached to a length of
Teflon® tubing was installed at the base of each borehole. Filter sand was then placed within the
annulus of the boring from the bottom of the boring to a depth of approximately 6 inches above
the top of the vapor screen. The sampling points were completed by placing hydrated bentonite
from the top of the filter sand to the ground surface. Boring logs including lithologic
descriptions, field screening results, and soil gas monitoring point construction details are
13
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/United Air Filter/Phase II/Draft to Client/Limited Phase II ESA Report_UAF.doc
provided in Appendix C.

Sub-Slab Soil Gas Sample Point Installation
H&H installed four (4) sub-slab soil gas sample points (SSV-1 through SSV-4) within the
approximate four quadrants of the existing Site building to evaluate conditions below the
building slab in areas where various manufacturing activities have historically been conducted.
The locations of the sub-slab soil gas sampling points are shown on Figure 2.

The sub-slab soil gas sampling points were installed using a rotary hammer drill and 1½-inch
diameter drill bit to advance a pilot hole into the concrete slab to a depth of approximately 1¾
inches below the surface. A drill guide was then placed in the pilot hole and a 5/8-inch diameter
drill bit was utilized to advance the boring through the concrete slab and approximately 6 inches
into the underlying soil. Following concrete borehole advancement, loose concrete cuttings were
removed from each boring using a bottlebrush. A Cox-Colvin Vapor Pin™ (vapor pin) assembly
(stainless-steel sampling point and silicone sleeve) was then seated in the boring using an
installation/extraction tool and hammer. Upon installation of the vapor pin assembly, the point
was capped with a silicon tip and finished at slab grade with a flush-mount stainless steel cap.

Exterior and Sub-Slab Soil Gas Sampling
Each exterior and sub-slab soil gas sample was collected utilizing a laboratory-supplied 1-liter
Summa® canister connected to an air-flow regulator calibrated by the laboratory to collect the
soil gas sample at a rate of no greater than approximately 200 milliliters per minute (mL/min).
Prior to collection of the soil gas samples, “shut-in” tests were conducted on the sampling train
and helium leak checks were conducted at each sampling point. The results of the shut-in test
and helium leak checks are documented in the soil gas sampling forms provided in Appendix E,
and a description of the shut-in test and helium leak testing procedures is provided below.

The shut-in test was conducted by connecting the flow regulator with the vacuum gauge to the
Summa® canister and sealing the flow regulator with the laboratory-provided brass cap. Once the
sampling train was “closed,” the sample valve on the Summa® canister was opened and the
reading on the vacuum gauge was recorded. The Summa® canister sample valve was then closed
14
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/United Air Filter/Phase II/Draft to Client/Limited Phase II ESA Report_UAF.doc
and the vacuum gauge was observed to ensure no vacuum loss occurred. If the vacuum reading
remained the same, the shut-in test was considered successful. If vacuum loss occurred, the flow
regulator and/or brass cap was reseated and the shut-in test was repeated until the vacuum
reading remained stable.

Following the shut-in test, the Summa® canister was connected to the sample point via Teflon®
sample tubing using a brass nut and ferrule assembly to create an air-tight seal, and a leak check
was performed. The leak check was performed by constructing a shroud over the sampling train
and flooding the shroud with helium gas. Helium concentrations inside the shroud were
measured using a helium gas detector. Once helium concentrations stabilized within the shroud,
the sample tubing was purged outside of the shroud using a syringe and a three-way valve to
collect purged soil gas into a Tedlar® bag. The purged soil gas was then analyzed using the
helium gas detector to ensure that helium concentrations in the soil gas sample were less than
10% of the helium concentrations measured within the shroud. Each soil gas sampling point
passed the helium leak check criteria.

Following successful leak checks, the soil gas samples were collected by opening the intake
valve on the Summa® canister. Vacuum readings on the Summa® canister were recorded prior to
and following the sampling period to ensure adequate sample volume was collected. A vacuum
of approximately 5 inches of mercury or more was maintained within the canisters at the
conclusion of the sampling event in accordance with DEQ DWM guidance. Additionally, H&H
collected one duplicate sub-slab soil gas sample from the SSV-1 point for QA/QC purposes.
Following sample collection, the Summa® canisters were shipped to Con-Test under standard
chain of custody protocols for analysis of VOCs by EPA Method TO-15. Upon receipt of the
samples, the laboratory recorded the final received vacuum pressure for each Summa® canister.

After sampling was completed, the sample locations were estimated by measuring from known
benchmarks within the Site buildings or using a GPS unit. The sample locations were abandoned
and the surfaces were repaired similar to pre-drilling conditions.

5.2 Soil Gas Sampling Results
A tabular summary of the soil gas sample analytical results is provided as Table 3. Laboratory
analytical results for the soil gas samples were compared to DEQ DWM Residential and Non-
Residential Vapor Intrusion Sub-Slab and Exterior Soil Gas Screening Levels (SGSLs) dated
January 2023. A copy of the laboratory analytical report and chain of custody record is provided
in Appendix D.

Exterior Soil Gas Sampling Points
Multiple VOCs were detected above laboratory method detection limits in the exterior soil gas
samples. Laboratory analytical results indicated the presence of tetrachloroethylene (PCE) at
concentrations exceeding the DEQ DWM Residential SGSL of 280 µg/m3 in samples SG-1
(480 µg/m3), SG-3 (380 µg/m3), and SG-4 (320 µg/m3). No other compounds, including the
chlorinated solvent TCE, were detected at concentrations above the DEQ DWM SGSLs in the
exterior soil gas samples.

Sub-Slab Soil Gas Sampling Points
Multiple VOCs were detected above laboratory method detection limits in the sub-slab samples.
Laboratory analytical results indicated the presence of benzene at a concentration exceeding the
DEQ DWM Residential SGSL of 12 µg/m3 in sample SSV-4 (28 µg/m3) collected from the
southeastern portion of the existing Site building. The compound 1,3-butadiene was also detected
at a concentration exceeding the DEQ DWM Residential SGSL of 3.1 µg/m3 in sample SSV-
1/SSV-DUP (3.5 µg/m3 / 3.5 µg/m3) collected from the northwestern portion of the existing Site
building. No other compounds were detected at concentrations above the DEQ DWM SGSLs.

PCE was detected in each of the sub-slab soil gas samples at concentrations above laboratory
method detection limits but below DEQ DWM SGSL of 280 µg/m3. TCE was not detected above
the laboratory method detection limits in the sub-slab soil gas samples collected from within the
existing Site building.

5.3 Vapor Intrusion Risk Evaluation
DEQ Vapor Intrusion SGSLs are very conservative and based upon a TCR of 1 x 10-6 for
potential carcinogenic effects and a HQ of 0.2 for potential non-carcinogenic effects. Vapor
intrusion mitigation or additional assessment is not typically warranted if the calculated LICR is
1 x 10-4 or less and the acceptable level for non-carcinogenic risk is a calculated cumulative HI
of 1.0 or less.

H&H utilized the DEQ Risk Calculator (January 2023) assuming both residential and non-
residential land use scenarios to further evaluate potential cumulative risks for the soil gas to
indoor air vapor intrusion pathway for future proposed buildings. To model the potential for
vapor intrusion under a hypothetical “worst-case” scenario, H&H conservatively calculated the
cumulative risks using the highest concentration of any compound detected in any exterior or
sub-slab soil gas sample collected from the Site. Risk calculator results are summarized in the
table below. A copy of the completed risk calculators is provided in Appendix F.

Risk calculator results indicate that under a hypothetical worst-case scenario for the soil gas to
indoor air vapor intrusion pathway for residential and non-residential use, the cumulative LICR
is less than the acceptable risk level of 1 x 10-4. Additionally, the cumulative HI for residential
and non-residential use is less than the acceptable risk level of 1.
Land Use Scenario Calculated Cumulative LICR Calculated Cumulative HI Exceedance of Acceptable Levels?
Residential 5.4 x 10-6 0.49 No
Non-Residential 4.1 x 10-7 0.039 No

6.0 Quality Assurance – Quality Control

For quality assurance and quality control purposes (QA/QC), non-dedicated equipment and tools
were decontaminated prior to use at each boring or sampling location or following exposure to
soil. Field QA/QC samples were analyzed along with the investigative samples to determine
potential variability introduced in sampling, handling, shipping, and analysis. H&H collected one
duplicate soil and one duplicate sub-slab soil gas sample to evaluate the ability of the laboratory
to reproduce sample results. Duplicate samples were submitted to the laboratory for the same
analysis as the corresponding parent sample.

Duplicate samples were collected to evaluate the precision of the field sampling procedures,
sample matrix variability, and analytical reproducibility. The duplicate soil sample was collected
directly into individual laboratory-supplied sample containers using sampling methodologies
described in previous sections. The duplicate sub-slab soil gas sample was collected concurrently
with the parent sample using a laboratory-supplied T-fitting which allows for collection of two
soil gas samples from one soil gas sampling point simultaneously. The samples were analyzed
for the same parameters as the parent samples, and the analytical results were compared with
those of the parent sample. The analytical results of the parent sample and the duplicate sample
were used to evaluate the cumulative precision of the analytical method, sample matrix, and
sample collection techniques.

Duplicate sample laboratory analytical results for each sample media are presented in the
summary tables (Table 1 for soil and Table 3 for soil gas, respectively). A review of the
duplicate sample results in comparison to the parent sample results indicates similar
concentrations and are within typical laboratory variability. Results of the duplicate samples
indicate good analytical laboratory analytical reproducibility.

7.0 Summary and Conclusions

H&H conducted Limited Phase II ESA activities at United Air Filter Company located at
1000 West Palmer Street in Charlotte, Mecklenburg County, North Carolina. The Limited Phase
II ESA activities included the collection of soil and soil gas samples for laboratory analysis to
evaluate the potential for impacts at the Site associated with historical on-Site and nearby off-
Site operations and to evaluate risks associated with proposed redevelopment of the Site. A brief
summary of the Limited Phase II ESA activities is provided below.

Receptor Survey
The results of the receptor survey did not identify the presence of private water supply wells
located on properties within 1,500 ft of the Site. H&H did not observe any structures with
potential basements within a 1,000 ft radius of the Site during the visual reconnaissance.

Soil Sampling
Results of soil sampling activities completed within the existing Site building did not identify
organic compounds at concentrations above the DEQ PSRGs. Concentrations of arsenic and
hexavalent chromium were detected at concentrations above the DEQ Residential PSRGs but
below Site-specific and/or published background concentrations for metals.

Elevated concentrations of lead were detected in some of the background samples collected at
the Site. TCLP lead analysis was performed on the background samples that contained elevated
lead concentrations above the “Rule of 20.” The laboratory analytical results of the TCLP
analysis did not indicate the presence of lead above the characteristically hazardous waste
criteria.

Laboratory analytical results of the background samples also indicated the presence of
hexavalent chromium above laboratory method detection limits. Hexavalent chromium can be
associated with anthropogenic activities but can also occur naturally in the environment. The
concentrations of hexavalent chromium detected in the background samples exceeded the
Residential PSRG of 0.31 mg/kg and ranged from 0.621 J mg/kg [BG-3 (2-4)) to 5.11 mg/kg
19
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/United Air Filter/Phase II/Draft to Client/Limited Phase II ESA Report_UAF.doc
(BG-1 (0-2)].

The elevated lead and hexavalent chromium concentrations are likely attributable to surrounding
property use and operations by Charlotte Pipe and Foundry and/or former industrial operations in
the Site area. Remaining metal concentrations in the background samples generally aligned with
published naturally occurring levels in North Carolina soil.

To further evaluate the cumulative exposure risks associated with the concentrations detected in
soil, H&H utilized the DEQ Risk Calculator under to model hypothetical “worst-case”
residential and non-residential land use scenarios using the highest concentration of any
compound detected in any soil sample collected from the Site. Results of the risk calculation
indicate that the calculated cumulative risks for direct soil exposure did not exceed acceptable
carcinogenic or noncarcinogenic risk levels for residential and non-residential use scenarios.

Soil Gas Sampling
Results of the exterior soil gas assessment activities indicated the presence of PCE at
concentrations above the DEQ DWM Residential SGSLs in samples SG-1, SG-3, and SG-4.
Results of the interior sub-slab soil gas assessment activities identified benzene and 1,3-
butadiene at concentrations above the DEQ DWM Residential SGSLs.

To further evaluate potential vapor intrusion risks for the proposed Site buildings, H&H utilized
the DEQ Risk Calculator (January 2023) assuming a “worst-case” residential and non-residential
land use scenario to further evaluate potential cumulative risks for the soil gas to indoor air vapor
intrusion pathway for the existing Site building and future redevelopments at the Site. Risk
calculator results indicate the cumulative LICR and HI for residential and non-residential use are
below the DEQ-acceptable risk threshold.

Recommendation
The Site received eligibility into the Brownfields Program in a letter dated May 24, 2023. The
Limited Phase II ESA activities described herein were designed to be consistent with assessment
activities typically requested by the DEQ Brownfields Program to evaluate the potential for
20
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/United Air Filter/Phase II/Draft to Client/Limited Phase II ESA Report_UAF.doc
impact and risks associated with redevelopment. Assessment results indicate that Site media can
be easily managed in accordance with a DEQ Brownfields Program approved Environmental
Management Plan. Based on the results of the Limited Phase II ESA, H&H recommends that this
Limited Phase II ESA report be provided to DEQ to address certain data gaps and discuss
potential next steps for the Site.

UAF-001
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL - Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean-Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.
ANALYTE QUALIFIERS
Common Laboratory Contaminant.C9
The sample and duplicate results for this parameter are less than 5 times the reporting limit, the RPD may not be
statistically valid.D8
Analyte concentration exceeded the calibration range. The reported result is estimated.E
This analyte exceeded secondary source verification criteria high for the initial calibration. The reported results should be
considered an estimated value.IH
Analyte detected below the reporting limit, therefore result is an estimate. This qualifier is also used for all TICs.J
Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results for this analyte in associated
samples may be biased high.L1
Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.M1
The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A
complete list of accreditations/certifications is available upon request.N2
Matrix spike recovery was outside laboratory control limits due to a parent sample concentration notably higher than the
spike level.P6
The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the
associated samples may have a high bias.v1
The continuing calibration verification was below the method acceptance limit. The analyte was not detected in the
associated samples and the sensitivity of the instrument was verified with a reporting limit check standard.v2
