Specialty Cleaners, DSCA Site ID DC110015
246 Tunnel Road
Asheville, Buncombe County, North Carolina
Dear Ms. Rivera:
AECOM Technical Services of North Carolina, Inc. is pleased to provide the attached Prioritization Assessment Report
(PAR) for the Specialty Cleaners (Site) located at 246 Tunnel Road in Asheville, Buncombe County, North Carolina.
The assessment activities documented herein were completed in accordance with AECOM Assessment Cost
Proposal (ACP), dated June 12, 2023, as approved June 15, 2023, by DSCA under State Lead Authorization for Work
(SLAW) 001 and subsequent Change Order 001B, dated September 27, 2023 as approved by DSCA September 28,
2023. A Site Location Map is included as Figure 1, and a Monitoring Well Location and Site Features Map is included
as Figure 2.
Background
The former Specialty Cleaners previously occupied a standalone building at the 246 Tunnel Road property and
operated between 1957 and 1973. The dry cleaner is no longer in operation and the building was likely demolished
when an approximate 51,000 square foot building was reportedly constructed in 1973, which is currently occupied by
Rooms To Go. As shown on Figure 3, the Site and properties to the west, north and east are currently zoned as
Highway Business Zoning, which is for commercial use, while properties to the south are zoned as “Urban Place” and
are currently commercial businesses.
To date, numerous soil, groundwater, and vapor intrusion (VI) assessment and sampling activities have been
completed at and near the Site under directives issued by the North Carolina Department of Environmental Quality
(NCDEQ), Division of Waste Management (DWM) – Inactive Hazardous Sites Branch (IHSB) for Site ID
NONCD0001221, generally called the “South Tunnel Road Solvents Site.” Reports associated with the “South Tunnel
Road Solvents Site” that were reviewed as part of this document include the following:

Due to soil gas and groundwater contamination identified by ATC (2023) and historic presence of a dry-cleaners at
246 Tunnel Road, the Site was certified as DSCA Site DC110015 on May 18, 2023 with Marvin Pearlman of Skip
Pearlman LLC listed as the petitioner. Additional information is included in the Assessment Report Forms (ARF)
included in this PAR.
To date, two site reports have been prepared for the Site under the DSCA Program:
-Indoor Air and Sub-Slab Vapor Sampling Report – July 2023, dated August 11, 2023 (AECOM, 2023a).
-Public Notification Summary Completion Letter,dated December 28, 2023 (AECOM, 2023b).
Analytical data from the reports referenced above have been incorporated into the ADTs and the most recent
analytical data are included in figures included in this PAR.
This report documents additional assessment activities conducted from October to April 2024.
Site Investigation and Analytical Results
AECOM personnel mobilized to the Site in October, November, and December 2023 and again in January and April
2024 to conduct Prioritization Assessment Activities. As part of the site prioritization assessment activities, AECOM
installed and sampled ten soil borings (SB-1 through SB-10), collected five soil gas samples (SG-8 to SG-12) and
installed four monitoring wells (MW-101S, MW-101D, MW-102 and MW-103). AECOM sampled those four
groundwater monitoring wells plus monitoring wells MW-6S and MW-6D, which were installed in March 2023 and
documented in a Soil-Gas and Groundwater Assessment Report by ATC and dated May 19, 2023.
Laboratory analytical results are summarized in the appropriate figures and ADT forms included herein, and laboratory
analytical reports are included as Appendix A.
Soil Sampling
As indicated on Figure 4, soil borings SB-1 through SB-10 were advanced, in areas where the former Specialty
Cleaners building was located, to further delineate soil impacts previously documented by ATC (ATC, 2023). Soil
borings were advanced using a GeoProbe® 6712D utilizing direct-push technology (DPT) to 10 feet below ground
surface (bgs) and screened using a photoionization detector (PID). A sample was collected from the 0 to 1 foot
interval, and then the next 1-foot interval with the highest PID reading. The soil samples were submitted to Pace
Analytical Services, LLC of Huntersville, North Carolina for laboratory analysis of volatile organic compounds (VOCs)
per EPA Method 8260D. Boring logs are included as Appendix B.
Based on a review of the laboratory analytical results, tetrachloroethylene (PCE) is present in nineteen soil samples at
concentrations above the applicable preliminary soil remediation goal (PSRG) of 0.0063 milligrams per kilogram
(mg/kg). Based on soil quality data collected to date, soil impacts are not delineated to the PSRG to the north, south,
east or west. Based on the proximity of the soil samples to Tunnel Road it is assumed that soil impacts extend
beneath the right-of-way of the road. Analytical results are summarized on Figure 4 and ADT 2.
aecom.com 3/5
Soil Gas Sampling
On November 1, 2023, AECOM personnel collected five soil gas samples (SG-8 through SG-12) to further evaluate
the extent of vapor intrusion risk along the southern property boundaries of the subject property. The locations of soil
gas samples SG-8 through SG-12 are indicated on Figure 5. Soil gas sample locations SG-08, SG-09, SG-10, SG-11,
and SG-12 were installed to 5 feet bgs using direct-push technology (DPT) and constructed per the AMS Vapor
Implants Sampling Method as described in the AECOM Soil Gas Sampling Standard Operating Procedures (SOP) as
provided in change order 001B, dated September 27, 2023. The soil gas borings were abandoned following the
completion of each sampling event. The soil gas sampling form is included as Appendix C.
The vapor samples were submitted for PCE, TCE, cis-1,2-dichloroethene (cis-1,2-DCE), trans-1,2-dichloroethene
(trans-1,2-DCE) and vinyl chloride analysis by EPA Method TO-15. Analytical results are summarized on Figure 5 and
on ADT 3. Analytical results were input into the DSCA Soil Gas and Indoor Air Risk Calculators, which are included in
Appendix D. Results from the risk calculators are summarized in the table below.

CR = Calculated cumulative carcinogenic risk; acceptable calculated risk values are less than 1E-04.
HI = Calculated non-carcinogenic hazard quotient; acceptable hazard index values are less than 1.0.
Red = Value exceeds acceptable CR or HI
Green = Value is acceptable CR or HI
As indicated on Figure 5, and summarized on the table above, soil gas samples SG-08 and SG-12 indicate potential
vapor intrusion risk exceeding calculated risk for residential exposure but not for non-residential worker exposure
along the property boundaries to the west (SG-08 and SG-09) and southeast (SG-12) of the subject property. Soil gas
samples SG-10 and SG-11, located along the southwest property boundary, indicate potential vapor intrusion risk
exceeding calculated residential and non-residential exposure risk. As Tunnel Road is the adjacent property to soil
gas samples SG-10 and SG-11, an immediate vapor intrusion risk is not apparent; however, property located on the
southwestern side of Tunnel Road is a potential vapor intrusion exposure risk.Figure 5 also includes soil gas and
sub-slab vapor collected during previous onsite investigations (AECOM, 2023a, ATC, 2023) and offsite investigations
(S&ME, 2019, ECS, 2022).
Monitoring Well Installation
AECOM installed four monitoring wells (MW-101S, MW-101D, MW-102 and MW-103) November 13-15, 2023 at the
locations shown on Figure 2. Each monitoring well was installed using 4.25” hollow-stem augers, with the exception
of MW-101D which transitioned from hollow-stem augers to air rotary drilling when competent bedrock was
encountered at approximately 50 feet below ground surface (bgs). Monitoring well installation depths varied between
39.8 feet bgs and 86.5 feet bgs. Top of casing elevations of the onsite monitoring wells were surveyed on January 4,
2024 using global positioning satellite (GPS) equipment. A Groundwater Elevation Map, utilizing survey data of onsite
monitoring wells in addition to top of casing elevations in the Soil-Gas and Assessment Report (ATC, 2023) is included
as Figure 6. Well installation logs are included as Appendix E.
During installation of monitoring well MW-103, a geotechnical sample was collected from 5 to 7 feet bgs using a
Shelby tube to obtain characteristics of the vadose zone soils. The sample was submitted for grain size analysis,
specific gravity, dry bulk density, porosity, water content, total organic carbon via Walkley Black method. The soils
were classified as a non-plastic silty sand (SM) via USCS classification and as clay loam via USDA classification. The
results of the other analyses are included in ARF 5. The laboratory report is included in Appendix A.

Groundwater Sampling
On November 27, 2023, AECOM conducted a sitewide groundwater gauging and sampling event of the newly
installed wells and two wells (MW-6S and MW-6D) installed by another consultant (ATC, 2023). Prior to sampling,
each well was gauged for depth to water. Water was not encountered in either monitoring well MW-101S or MW-
101D.
After obtaining an access agreement to the Eastvale Shopping Center and exhausting efforts to gain access to the
former Sears Maintenance facility property (now owned by Ingles Supermarkets), AECOM performed gauging of site
and offsite monitoring wells on April 1, 2024 which included six onsite monitoring wells (MW-6S, MW-6D, MW-101S,
MW-101D, MW-102, MW-103) and ten offsite monitoring wells on the Eastvale Shopping Center property (CMW-1S,
CMW-1D, CMW-2S, CMW-2D, CMW-3S, CMW-3D, CMW-4S, CMW-4D, CMW-5S and CMW-5D). Because water
was present in both monitoring wells MW-101S and MW-101D, AECOM returned to the site on April 8, 2024 and
collected groundwater samples from monitoring wells MW-101S and MW-101D.
Groundwater elevations and potentiometric surface contours are summarized on ADT 7 (November 27, 2023 and
April 1, 2024) and presented on Figure 6 (April 1, 2024). Groundwater flows south beneath the Site toward the
Swannanoa River located approximately 3,000 feet south of the Site as indicated on Figure 1.
Groundwater samples were collected from monitoring wells MW-6S, MW-6D, MW-101S, MW-101D, MW-102 and
MW-103 using disposable bailers per the Standard Operating Procedure (SOP) for Groundwater Sampling Using
Disposable Bailers included as Appendix F. The samples were submitted for laboratory analysis of VOCs per EPA
Method 8260D. Water quality parameters including specific conductance, temperature, dissolved oxygen, and pH
were all measured and are provided on ADT 12. A figure depicting the results of the November 2023 and April 2024
groundwater sampling activities are summarized on Figure 7 and ADT 8. It should be noted that offsite groundwater
quality data collected under previous investigations (IT Group, 2000; ATC, 2017; ECS, 2018; ATC, 2022) are also
included on Figure 7 and are tabulated in ADT 8.
Chlorinated solvent constituents detected in groundwater as part of the recent groundwater sampling activities were
identified at monitoring wells MW-6S, MW-102 and MW-103. PCE was detected at a concentration of 3,640
micrograms per liter (µg/l) at MW-6S, at a concentration of 4.1 µg/l at MW-102 and a concentration of 0.57J µg/l at
MW-103. The concentrations detected at monitoring wells MW-6S and MW-102 are above the 15A NCAC 02L.0202
Groundwater Standard (2L Standard) of 0.7 µg/l. TCE was detected at a concentration of 81.1 µg/l at MW-6S. The 2L
Standard for TCE is 3 µg/l.
Analytical results were input into the DSCA Groundwater to Indoor Air Risk Calculators included in Appendix D, and
those results are summarized in the table below.

Receptor Survey
On November 27, 2023, AECOM completed a windshield survey to identify water supply wells (WSWs) and other
sensitive receptors located within a 0.5-mile radius of the Site. Ross Creek and Lake Kenilworth are located
approximately 2,000 feet to the south-southwest of the Site. No WSWs were identified during the windshield survey
portion of the investigation. Public notification letters were mailed July 6, 2023 to the Buncombe County Health
aecom.com 5/5
Director, the Asheville City Manager, and 28 property owners within a 500-foot radius of the former dry-cleaning
facility. The purpose of the mailing was to inform of environmental investigation activities at the former Specialty
Cleaners site. The Buncombe County Health Director and Asheville City Manager did not respond to the
correspondence and only two property owners returned response forms indicating their properties did not have WSWs
associated with them. As previously documented by AECOM (2024b), the receptor survey did not identify any WSWs
within the specified search radius.
Conclusions
To date, soil impacts have not been delineated to the PSRG. Further soil sampling is warranted to determine if soil
impacts above the PSRG are extending beyond the property boundary.
Soil gas results from SG-10 and SG-11, located in the front parking lot of the Rooms To Go building, indicate
unacceptable risk for residential and non-residential use and the results from SG-08, SG-09 and SG-12, also located
in the front parking lot of the Rooms To Go, are unacceptable for residential use. Previous investigations determined
that indoor air quality within the current Rooms to Go building (AECOM, 2023a) and Chili’s to the southwest (S&ME,
2019) is acceptable for residential and non-residential worker exposure. Further evaluation of soil gas to the north-
northwest of SG-08 and to the east-southeast of SG-12 is warranted.
Groundwater flow direction is to the south toward Tunnel Road, the Chili’s restaurant, Eastvale Shopping Center and
the former Sears auto maintenance facility. Groundwater impacts above the 2L standard have been identified based
on recent and historical analytical data from on-site monitoring wells MW-6S and MW-102 and 22 off-site monitoring
wells. Based on the available groundwater quality data as depicted on Figure 7, the groundwater plume extends
offsite to the south across multiple properties. The groundwater plume is not delineated to 2L Standards.
In respect to the usability and reliance of the soil gas, soil and groundwater analytical results provided by Pace -
AECOM received laboratory reports from Pace dated November 13, 2023 (soil gas), November 15, 2023 (soil) and
December 8, 2023 and April 16, 2024 (groundwater).Pace is a North Carolina certified laboratory (North Carolina
Environmental Certificate #375). Based on AECOM’s review of the laboratory report(s), Pace did not identify any
quality assurance/quality control issues associated with the data, and the data are deemed usable for the purposes of
the assessment activities and conclusions documented in this submittal.

Vadose zone characteristics were measured (with the exception of effective porosity) through the
collection of one unsaturated soil smaple using a Shelby tube for various geotechnical analysis.
Saturated zone characteristics are estimated: Dry bulk density estimate based on median soil value
(ASTM, 1995). Total porosity, effective porosity, and water content estimate based on observations of
similar soils at other locations (Pec et al, 1974 and Domenico et al, 1990).

Table 5(2): Additional Data for Indoor and Outdoor Air
DSCA ID No.: DC110015
Attachment:
Sampling location map that indicates where all indoor air samples were collected. The map should clearly indicate the names/types of businesses and residence names sampled and in the vicinity of the
subject site that may be of concern.
Is dry-cleaning facility at the site: Operating Pick-up Only Abandoned
If facility is operating, solvents used are: Perc Petroleum Green Earth Other
For the active or former dry-cleaning space, describe the type and location of the air handling/HVAC unit (for example - a shared unit supplying two adjacent spaces; unit located on the roof):
The former Specialty Cleaners reportedly operated between 1957 and 1973. The dry cleaner is no longer in operaton and the building was likely demolished when an approximate 51,000 square-foot
building was reportedly constructed in 1973 which is currently occupied by a Rooms To Go furniture store.
For any other indoor spaces tested, describe the type and location of the air handling/HVAC unit (for example - a shared unit supplying two adjacent spaces; unit located on the roof):
Not applicable.
For any indoor air spaces tested, describe the current use of the space (for example - an ABC liquor store adjacent to the dry-cleaner, a residence approximately 200 feet from the dry-cleaner, etc.):
Not applicable.

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
Analyte detected below the reporting limit, therefore result is an estimate. This qualifier is also used for all TICs.J
Surrogate recovery was above laboratory control limits. Results may be biased high.ST

Narrative
Job Narrative
400-247539-1
Analytical test results meet all requirements of the associated regulatory program listed on the Accreditation/Certification Summary Page
unless otherwise noted under the individual analysis. Data qualifiers are applied to indicate exceptions. Noncompliant quality control
(QC) is further explained in narrative comments.
Matrix QC may not be reported if insufficient sample or site-specific QC samples were not submitted. In these situations, to
demonstrate precision and accuracy at a batch level, a LCS/LCSD may be performed, unless otherwise specified in the method.
Surrogate and/or isotope dilution analyte recoveries (if applicable) which are outside of the QC window are confirmed unless attributed
to a dilution or otherwise noted in the narrative.
Regulated compliance samples (e.g. SDWA, NPDES) must comply with the associated agency requirements/permits.
Receipt
The sample was received on 11/30/2023 12:17 PM. Unless otherwise noted below, the sample arrived in good condition, and, where
required, properly preserved and on ice. The temperature of the cooler at receipt time was 22.3°C
Receipt Exceptions
The Chain-of-Custody (COC) was incomplete as received and/or improperly completed. No sample date or time provided. Sample was
given the date of 11.29.23 at 12pm

AECOM – North Carolina Standard Operating Procedures
Groundwater Sampling Using Disposable Bailers

1. Purpose and Scope
Standard operating procedures to collect groundwater samples using disposable bailers.
2. Procedure
2.1 Required Equipment
• HASP
• Field Note Book and sampling logs.
• Polypropylene rope, scissors (instrument to cut rope)
• Bailer
• Electronic water level indicator or oil-water interface probe
• Collection container (5-gallon buck or similar container)
• PPE
• Sample bottles
• Calculator
• Water Quality Meter
2.2 Procedure
1. Review HASP. The field technician will don nitrile (or other HASP-approved gloves based on
contaminants) gloves for all associated field work and sampling.

2. Open all wells to be sampled and allow equilibration time. Well caps should be placed adjacent to the monitoring wells on a clean area such as a small piece of plastic or towel.
3. Measure static water levels and total depth of well using the electronic water level indicator, or other similar device, and utilizing decontamination procedures to
decontaminate the water level indicator before measuring water levels in the first well, between each well, and after completion of all water level measurements.
4. Calculate and record in the field book the volume of water in each well casing to be
sampled. Sometimes this may be performed prior to field activity.

Calculate borehole volume using formula: v =
π r2 L Where:
v = Volume
L = Length of well, and
r = Radius of well

24 23.50
36 52.90
5. Record the required purge volume in the field book (this should be three times the calculated volume of water in the well casing) and sample log. Purge at least the required volume of water from the monitoring well using a new or dedicated bailer and a new length of polypropylene rope secured tightly to the top of the bailer.
6. Place purge water in collection container for measurement purposes. Record in the field book the total amount of water purged from the well. Place purge water on ground, in 55-gallon drum or in other storage container as specified in work plan. If the well bails dry prior
to the removal of three well volumes, record the amount of water purged, allow the well to recharge. It is not necessary to remove three well volumes from wells that bail dry.
7. Water level and water quality parameters (pH, specific conductance, dissolved oxygen and
turbidity) need to be measured following purging.

8. Lower the bailer back into the well to collect sample. Place groundwater directly into laboratory supplied sample containers with appropriate preservatives (if required). If filtering
is required for analysis, place water in unpreserved bottle, and request that laboratory filter sample. If additional groundwater is required to fill all necessary sample bottles, lower bailer back into well and collect additional groundwater. Seal container.

9. Label sample bottles – date, time, project identifier, sample location, depth (if required), required analysis, preservative (if used), and sampler’s initials. Place samples in cooler with ice. Complete chain-of-custody form (supplied by the laboratory) and record site activities
in field log book. Pack cooler for shipping or deliver samples to laboratory. Retain a copy of chain-of-custody and submit other copies with samples. Close and secure all wells.
