Re: Prioritization Assessment Report
Miller’s Laundry and Cleaners

Hendersonville, Henderson County
DSCA ID No. DC450006
H&H Job No. DS0-174A

Dear Eric:

Hart & Hickman, PC (H&H) is submitting this report to document prioritization assessment (PA)
activities associated with the Miller’s Laundry and Cleaners site located at 423 N. King Street in
Hendersonville, Henderson County, North Carolina. The site activities included assessment of
soil, groundwater, and vapor intrusion impacts. A receptor survey and public outreach mailing
were also completed. A brief summary of the activities is provided below, and the results are
documented in the attached tables and figures.

Soil Assessment
Previous soil sampling was performed at the site in August 2022 by Mid-Atlantic Associates, Inc.
(Mid-Atlantic) and included the collection of two soil samples from one boring (SB-1) advanced
adjacent to the dry-cleaning machines. The dry-cleaning solvent tetrachloroethylene (PCE) was
detected in both soil samples at concentrations up to 214 milligrams per kilogram (mg/kg), which
exceeds Residential, Commercial, and Protection of Groundwater Preliminary Soil Remediation
Goals (PSRGs). Additionally, naphthalene and trichloroethylene (TCE) were detected at
concentrations exceeding PSRGs.

Cleaners/Reports/PAR/Final for Review/DC450006_CoverLetter.docx

In February and July 2023, H&H collected soil samples from twelve borings (SB-1 through SB-
12) to further evaluate impacts at the site. The soil borings were advanced to depths ranging from
3 to 10 ft below ground surface (bgs), and two soil samples were collected from each boring. One
soil sample was collected from a shallow interval (0-1 ft bgs), and one sample was collected at the
depth of the highest photoionization detector (PID) reading.

PCE was detected at concentrations above PSRGs in 17 of the 24 soil samples collected. The
highest PCE concentration (274 mg/kg) was detected in SB-3 (1-2) located inside the facility near
the dry-cleaning machines. TCE was also detected above PSRGs in three soil samples, and
naphthalene was detected above PSRGs in two soil samples. One soil sample SB-7 (6-7), located
west of the former dry-cleaning machines, indicated concentrations of methylene chloride (0.477
J mg/kg) and 1,2,4-trimethylbenzene (16.7 mg/kg) above PSRGs. Soil impacts extend onto
adjacent off-source properties to the south. Additional assessment is needed to further delineate
soil impacts at the site.

Monitoring Well Installation and Sampling
In February 2023, H&H contracted with AmeriProbe, a NC licensed driller, to install one 1-inch
temporary monitoring well (TMW-1) and three 2-inch permanent monitoring wells (MW-1
through MW-3) on the source property to evaluate groundwater impacts. The monitoring wells
were installed to depths between 22 and 25 feet below ground surface (ft bgs) and constructed with
15 feet of screen. Depth to water (measured from top of casing) ranged between approximately
12 and 13 feet with groundwater flow direction to the east. Laboratory analytical results indicated
concentrations of PCE in each of the wells (up to 0.0240 milligrams per liter [mg/L]) at
concentrations above the NC 2L Standard. Low concentrations of TCE (0.000823 mg/L) and cis-
1,2-DCE (0.000326 J mg/L) were also detected in TMW-1 but below 2L Standards. Additional
groundwater assessment is needed to further delineate the contaminant plume.

Cleaners/Reports/PAR/Final for Review/DC450006_CoverLetter.docx

Vapor Intrusion Assessment
Initial vapor intrusion assessment activities were conducted in February 2023 and included the
collection of two sub-slab soil gas samples (SS-1 and SS-2) inside the dry-cleaning facility and
four exterior soil gas samples (SG-1 through SG-4) on the source property. Based on the results,
indoor air samples (IAS-1 and IAS-2) were collected inside the dry-cleaning facility in April 2023,
and additional assessment (soil gas and/or indoor air sampling) was conducted on the adjacent off-
source properties to the east, south, and west in July and August 2023.

For the dry-cleaning facility, high concentrations of PCE were detected in the sub-slab gas samples
(up to 1,700,000 micrograms per cubic meter [µg/m3]) and the calculated risks exceeded
acceptable levels for both residential and non-residential use. However, indoor air samples
collected inside the facility indicated acceptable risk levels for non-residential use with PCE (up
to 80 µg/m3), TCE (up to 1.9 µg/m3), and lower concentrations of cis-1,2-DCE, naphthalene,
and/or 1,2,4-trimethylbenzene detected in the samples. Exterior soil gas samples collected near
the dry-cleaning facility property boundaries indicated exceedances of acceptable risk levels near
the eastern, western, and southern property boundaries.

Additional soil gas sampling was conducted on the adjacent properties to the west, south, and east
to evaluate vapor intrusion risks. The soil gas sample results indicated acceptable risk levels in
the soil gas samples collected on properties to the west (SG-5, SG-6, and SG-7) and to the east
(SG-10 and SG-11); however, unacceptable residential and non-residential risks were indicated
for the soil gas samples collected to the south. Due to the high soil gas concentrations, indoor air
samples (IAS-4 through IAS-7) were collected from the adjacent commercial building to the south.
PCE (up to 4.4 µg/m3) and other constituents were detected in each of the indoor air samples. The
calculated risks associated with the detected indoor air concentrations were acceptable for both
residential and non-residential use.

Public Outreach Mailing and Receptor Survey
On February 10, 2023, a public notification and water supply well information request mailing
was sent to property owners within 500 feet of the source property. A mailing was also sent to City
and County officials, and H&H contacted the Henderson County Department of Public Health to
obtain information about potential wells in the area. The Henderson County Department of Public
Health stated that they started keeping records of private water supply wells in 1991. Per
Henderson County’s guidance, H&H used the County Geographic Information System (GIS)
website to evaluate whether properties had septic or water supply well permits. H&H was unable
to identify any septic or well permits within the search radius. Responses to the public notification
mailing did not identify water supply wells within 500 feet of the inferred extent of groundwater
impacts. H&H also conducted desktop research and a field survey to further evaluate potential
receptors in the site vicinity, and no water supply wells were identified. The nearest surface water
body is Mud Creek located approximately 2,000 ft to the southeast. Additional receptor
information is provided in the attached report forms and figures.

Data Usability Evaluation
Groundwater, soil, sub-slab gas, soil gas, and indoor air samples collected as part of PA activities
were submitted to either Waypoint Analytical (Waypoint) or Con-Test, a Pace Analytical
Laboratory (Con-Test) for analysis of VOCs by EPA Method 8260 or EPA Method TO-15. Based
on H&H’s review of the laboratory reports, the laboratories did not identify any quality
assurance/quality control (QA/QC) issues that impact the usability of the data for the purposes of
the assessment activities and conclusions documented in this submittal. As a result, the data are
deemed usable for the purposes of the assessment activities and the conclusions regarding PCE-
related dry-cleaning solvent impacts documented in this submittal.

Chronology of Events
August 2022 Mid-Atlantic Associates, Inc collected two soil samples from one soil boring (SB-1) located adjacent to the dry-cleaning
machine, and PCE was detected at concentrations above PSRGs.
September 2022 The site was certified into the DSCA Program.
February to August
2023
In February 2023, Hart & Hickman, PC (H&H) conducted initial prioritization assessment (PA) activities at the site, which
included collecting soil samples from nine soil borings (SB-1 through SB-9); installing and sampling one temporary
monitoring well (TMW-1) and three permanent monitoring wells (MW-1 through MW-3); collecting four exterior soil gas
samples (SG-1 through SG-4); collecting two sub-slab gas samples inside the dry-cleaning facility (SS-1 and SS-2);
conducting a receptor survey within 0.5 miles of the source property; and completing a public outreach mailing to
properties within 500 ft of the dry-cleaning facility and to City/County officials. In April 2023, H&H collected two indoor
air samples at the dry-cleaning facility. In July and August 2023, H&H collected indoor air (IAS-3 through IAS-7), soil
gas (SG-5 through SG-11), and soil (SB-10 through SB-12) samples at adjacent off-source properties to further evaluate
vapor intrusion risks and delineate soil impacts. In October 2023, H&H submitted a Priortization Assessment Report
documenting the assessment activities and results.

RE: Dry-Cleaning Solvent Contamination

DSCA Site ID DC450006

Dear Mr. Connet:

The North Carolina Division of Waste Management (Division) is conducting an environmental
assessment of a dry-cleaning solvent contamination site (site) ID DC450006 associated with
Miller’s Laundry & Cleaners at 423 North King Street in Hendersonville, North Carolina. You are
receiving this letter because the Division is performing site-related work in the area. We want to
make you aware of the activities being conducted and provide you with someone to contact if you
have questions.

The Division has a program that addresses releases of dry-cleaning solvent, called the Dry-
Cleaning Solvent Cleanup Act (DSCA) Program. Miller’s Laundry & Cleaners was certified into
the DSCA Program in November 2022 after information became available that a release of dry-
cleaning solvent had resulted in contamination, and we are currently investigating the extent of
that contamination in the area. Some activities that may be conducted are the following: searching
for water supply wells, collecting soil samples, installing and sampling groundwater monitoring
wells, indoor air sampling, etc. Obtaining samples from private properties may be a part of this
investigation.

The DSCA Program’s contractors will be reaching out to the Henderson County Health
Department to request records regarding possible water supply wells in the area. If you have
additional guidance on whom the contractors should contact, please respond to this letter via the
contact information indicated below.

If you would like to view the location of the Miller’s Laundry & Cleaners dry-cleaning facility site
or review additional reports for the site, please go to deq.nc.gov/ncdsca and view the instructions
for the use of the DWM Site Locator Tool and Online Documents. A figure showing the location
of the dry-cleaning facility is attached.

If you have questions, please contact the DSCA Program’s independent contractor for this project,
Ms. Jennifer Hoang with Hart & Hickman, PC at [e-mail] or [phone]. If
you still have questions after contacting Ms. Hoang, please contact the DSCA Program Project
Manager, Mr. Eric Rice at [e-mail] or [phone]. If the Division receives

RE: Dry-Cleaning Solvent Contamination
Miller’s Laundry & Cleaners
423 North King Street
Hendersonville, Henderson County, NC
DSCA Site ID DC450006

Dear Mr. Smith:

The North Carolina Division of Waste Management (Division) is conducting an environmental
assessment of a dry-cleaning solvent contamination site (site) ID DC450006 associated with
Miller’s Laundry & Cleaners at 423 North King Street in Hendersonville, North Carolina. You are
receiving this letter because the Division is performing site-related work in the area. We want to
make you aware of the activities being conducted and provide you with someone to contact if you
have questions.

The Division has a program that addresses releases of dry-cleaning solvent, called the Dry-
Cleaning Solvent Cleanup Act (DSCA) Program. Miller’s Laundry & Cleaners was certified into
the DSCA Program in November 2022 after information became available that a release of dry-
cleaning solvent had resulted in contamination, and we are currently investigating the extent of
that contamination in the area. Some activities that may be conducted are the following: searching
for water supply wells, collecting soil samples, installing and sampling groundwater monitoring
wells, indoor air sampling, etc. Obtaining samples from private properties may be a part of this
investigation.

The DSCA Program’s contractors will be reaching out to the Henderson County Health
Department to request records regarding possible water supply wells in the area. If you have
additional guidance on whom the contractors should contact, please respond to this letter via the
contact information indicated below.

If you would like to view the location of the Miller’s Laundry & Cleaners dry-cleaning facility site
or review additional reports for the site, please go to deq.nc.gov/ncdsca and view the instructions
for the use of the DWM Site Locator Tool and Online Documents. A figure showing the location
of the dry-cleaning facility is attached.

If you have questions, please contact the DSCA Program’s independent contractor for this project,
Ms. Jennifer Hoang with Hart & Hickman, PC at [e-mail] or [phone]. If
you still have questions after contacting Ms. Hoang, please contact the DSCA Program Project
Manager, Mr. Eric Rice at [e-mail] or [phone]. If the Division receives
comments indicating significant public interest, the Division will either perform an additional
mailing containing details regarding the site or hold a public information session to answer
questions from the public.

Sincerely,

Eric Rice, DSCA Project Manager
