2.0 PREVIOUS INVESTIGATIONS
ECS Southeast, LLP (ECS) and TRC Environmental Corporation (TRC) previously completed three
environmental assessment reports and one geotechnical engineering report, which included historical
environmental data research and soil, soil gas, and groundwater quality sampling and analyses. The scope
and findings of the prior assessment work includes the following:
• In 2005 during a Limited Phase II Environmental Investigation performed by TRC, two soil quality
samples, SB-1 and SB-2, and two groundwater samples, SB-1 and SB-4 were collected for analysis.
— Soil samples were analyzed for Volatile Organic Compounds (VOCs) and Semi- Volatile Organic
Compounds (SVOCs) did not reveal detections; and
— The groundwater sample from SB-4 which was located outside the former paint room of the
Wilson's Outdoor Equipment building, was analyzed for VOCs and SVOCs and detected two
constituents above the NCAC 2L Groundwater Quality Standards (NC2LGWQS or 2L) as well as
another constituent that did not have a standard. Naphthalene was detected at 26 micrograms
per Liter (µg/L) and the standard is 6 µg/L. Tetrachloroethene (PCE), a common solvent, was
identified at 2.3 µg/L and the standard is 0.7 µg/L. p-Isopropyltoluene was detected at 13 µg/L
and had no 2L standard. Laboratory analysis of the groundwater sample collected from SB-1 did
not report concentrations of analytes above their respective 2L.
• In August 2019, ECS performed a Phase I Environmental Site Assessment (Phase 1) for the subject
site and reported several recognized environmental conditions (RECs).
• In November 2019, ECS performed a Limited Phase II Environmental Site Assessment (Phase II) for
the subject site. Nine soil samples and nine groundwater samples were collected for analysis during
the Phase 11. Sample locations are depicted on Figure 3.
— Soil samples were analyzed for VOCs, SVOCs, RCRA-8 Metals, and hexavalent chromium (Cr VI).
Laboratory analysis of several samples reported concentrations of naphthalene, Cr VI, arsenic,
and/or total chromium that exceeded their respective residential and/or industrial/commercial
preliminary soil remediation goals (PSRGs).
— Groundwater samples were analyzed for VOCs, SVOCs, RCRA-8 Metals, and Cr VI. Laboratory
analysis of several samples reported concentrations of PCE, lead, barium, mercury, bis(2-
ethylhexyl)phthalate, and/or total chromium that exceeded their respective NC2LGWQS.
• ECS completed a Brownfields Assessment Report dated July 19, 2022 for the subject site. The
assessment included collection of three soil samples, fifteen groundwater samples, and fifteen soil
gas samples from the site. Sample locations are depicted on Figure 4.
— Soil samples were analyzed for VOCs, SVOCs, RCRA-8 Metals, and Cr VI. Arsenic was identified at
concentrations above its respective Protection of Groundwater PSRG in soil samples SS-1, SS-2,

and the duplicate of SS-1 (DUP-1); however, these concentrations did not exceed their respective
Residential or Industrial/Commercial PSRGs. The MDLs for Cr VI for the soil samples collected were
above the Protection of Groundwater PSRG for Cr VI, which ECS considers to be an exceedance
above its respective Residential PSRG. Based on the information from Sparks., DL. 2003.
Environmental Soil Chemistry, the concentrations of arsenic detected in the soil samples collected
are within the naturally occurring range of arsenic "Range <0.1 to 97 mg/Kg, Median 7.2 mg/Kg;
Sparks, DL. 2003.", and are likely resultant from naturally occurring or anthropogenic sources, and
not related to the historic use of the site.
— Groundwater samples were analyzed for VOCs, SVOCs, RCRA-8 Metals, and Cr VI. Review of the
groundwater analytical results identified multiple targeted VOCs above their respective
NC2LGWQS and Residential VISLs. Benzene was detected at a concentration above its NC2LGWQS
and Residential VISL in sample GW-7. Chloroform was identified above its respective Residential
VISL in groundwater samples GW-11, GW-12, and DUP-2. 1,2-Dichloroethane was detected at a
concentration at or above its NC2LGWQS in samples GW-7, GW-8, GW-12, and MW-1.
Additionally, the concentration of 1,2-Dichloroethane in groundwater sample MW-1 was above
its respective Residential VISL. 1,2-Dichloropropane was detected at a concentration above its
NC2LGWQS in sample GW-8. Naphthalene was detected above its NC2LGWQS and Residential
VISL in sample GW-1 and its duplicate (DUP-3). Tetrachloroethene (PCE) was detected above its
NC2LGWQS limit in groundwater samples GW-1 (its duplicate DUP-3), MW-2, and MW-3. Total
chromium and Cr VI were detected in groundwater sample GW-3 above their respective
NC2LGWQS. Total chromium was detected in groundwater sample GW-12 above its respective
NC2LGWQS. Concentrations of targeted compounds identified in the groundwater samples
discussed above did not exceed their respective Non -Residential VISLs.
— Soil gas samples were analyzed for VOCs. Laboratory analysis of the soil gas samples collected
identified concentrations of multiple VOCs above their respective Residential VISLs. SG-3 identified
benzene, chloroform, and 1,2-Dichloropropane above their respective Residential VISLs. SG-4
identified trichloroethene (TCE) above its respective Residential VISL. SG-5 and SG-7 identified
concentrations of Tetrachloroethene (PCE) above its respective Residential VISL. SG-9 identified
chloroform above its respective Residential VISL. SG-14 identified benzene and chloroform above
their respective Residential VISLs. Additionally, the concentration of ethylbenzene identified in
DUP-4 (the duplicate sample of SG-14) was above its respective Residential VISL. Concentrations
of the targeted compounds identified in the soil gas samples discussed above did not exceed their
respective Non -Residential VISLs.
— Based on the results of the NCDEQ Risk Calculator for groundwater, the groundwater
concentrations identified did not exceed the residential or non-residential risk threshold.
However, based on the results of the NCDEQ Risk Calculator for soil gas, the soil gas
concentrations identified exceeded the residential risk thresholds, but not the non-residential risk
thresholds. Therefore, the non-residential soil gas to indoor air risk was not exceeded.
3.0 OBJECTIVE OF THE ASSESSMENT
In accordance with the November 2018 Brownfields Program Work Plan Checklist, an in -situ assessment
of the soil at the Subject Site was necessary to support the future export of soil. The scope of this
assessment included 40 soil borings in 8 roughly equivalent sized cells, field screening, the collection of
15 representative composite soil samples, as well as one QA/QC sample per day of soil sampling activities

conducted for North Carolina certified laboratory analysis. The soil samples were submitted for laboratory
analysis of VOCs by EPA Method 8260, for SVOCs by EPA Method 8270, for RCRA 8-Metals by EPA Method
6020/7471, and for Cr VI by EPA Method 7199. Sample locations are illustrated on Figures 5 & 6.
The areas and soil boring locations are shown on Figures 5 & 6. The samples were collected in a celled
approach and at incremental depths in order to provide a better horizontal characterization of the soil. As
depicted on Figure 5, the site has been broken into 8 individual cells. Due to varying cut and fill depths
across the site, ECS calculated the approximate amount of soil to be cut in each area, then divided soil to
be assessed into two depth intervals, 0 to 5 feet below ground surface (bgs) and 5 feet bgs to the
estimated termination depth of the proposed excavation in that area. The overall required number of
samples to be analyzed by the laboratory were minimized by utilizing this horizontal composite sampling
method. The sampling approach resulted in varied frequencies and no less than one sample per 1,070
cubic yards.
The data obtained from executing this assessment is intended for regulatory use by the Brownfields
Program only. The sampling activities were conducted in general accordance with the Brownfields
Environmental In -Situ Soil Assessment Work Plan Rev. 1.0 (Work Plan) prepared by ECS (ECS Project No.
49:9772-C) dated May 24, 2022, and approved by the NCDEQ Brownfields Program on May 24, 2022.
4.0 FIELD ACTIVITIES
4.1 Soil Samples
Number and Sample Location
On May 23, 2022 through May 27, 2022, ECS conducted the soil sampling field activities in general
accordance with the approved Work Plan. ECS requested that the drilling contractor advance soil borings
located in Cell 1 (B-1 through B-5) on May 23rd. ECS then proceeded to Cell 7 (B-31 through B-35) and Cell
2 (B-6 through B-10) on May 241"; Cell 5 (B-21 through B-25) and Cell 6 (B-26 through B-30) on May 251";
Cell 8 (B-36 through B-40) on May 261"; and Cell 3 (B-11 through B-15) and Cell 4 (B-16 through B-25) on
May 27t". Prior to advancement of the borings located within the buildings, a core drill was utilized to drill
through the concrete slab at each boring location. Borings were advanced from ground surface to the
termination depths ranging from 5 feet bgs to a minimum of 12 feet bgs as indicated in Table 1. The
exterior borings were advanced using a track mounted direct push technology (DPT) drill rig. Interior
borings were advanced using a specialty DPT drill rig. The boring locations are shown on Figures 5 & 6.
Sample Collection and Analysis
Depths sampled were in five-foot increments and with maximum boring termination depths varying due
to existing grade and redevelopment cut plans. ECS removed the soil cores from the disposable PVC liners
produced by the DPT drill rig, visually classified the soil collected from each boring, and screened the soil
samples for relative levels of volatile organic vapors using a photoionization detector (PID). If elevated
volatile organic vapor concentrations or visual/olfactory observations indicated evidence of soil impacts,
ECS denoted on the soil boring logs. Borings were abandoned by the driller upon completion in accordance
with NCAC 2C standards. Boring logs for each soil boring are included in Appendix A.

ECS Project No. 49:9772-D
August 8, 2022, Revised August 24, 2022
The samples were analyzed by EPA Method 8260 for VOCs, EPA Method 8270 for SVOCs, EPA Method
6020/7471 for RCRA 8-Metals. For VOCs, a grab sample was collected from the boring within each celled
area that contained the highest relative levels of volatile organic vapors within that five-foot vertical
increment. VOC samples will be taken directly from the core; soil that has been screened with the PID will
be ineligible for sampling.
Following the collection of representative VOC samples, SVOCs, RCRA 8-Metals, and Cr VI samples were
composited by gently mixing the five representative samples collected from each celled area's similar 5
foot depth horizons which resulted in a celled horizontal composite sample. Samples were collected into
laboratory supplied/preserved containers. Following collection, they were placed within an ice chilled
cooler for courier transportation to the laboratory. One (1) duplicate (non -background) soil sample was
collected per day during the soil assessment for Quality Assurance/Quality Control (QA/QC) purposes. The
duplicate(s) were submitted for the same soil analyses as the sample it duplicated (Table 2).
5.0 RESULTS
5.1 Soil Boring Soil Analysis
Laboratory analysis of soil samples 131-1, 131-2, 132-1, and 132-2 detected concentrations of hexavalent
chromium and arsenic above their respective Residential Preliminary Soil Remediation Goals (PSRGs). 133-
1 and 138-1 detected concentrations of Arsenic above its respective Residential PSRG. 133-2, 135-1, 136-1
detected arsenic above its respective Residential and Industrial/Commercial PSRG as well as hexavalent
chromium above its respective Residential PSRG. 134-1 detected arsenic above its residential and
Industrial/Commercial PSRGs. 135-2, 136-2, and 138-2 detected arsenic and hexavalent chromium above their
respective Residential PSRGs as well as selenium above its respective Protection of Groundwater PSRG.
136-1 detected arsenic above its respective Residential and Industrial/Commercial PSRG, selenium above
its protection of groundwater PSRG, and hexavalent chromium above its respective Residential PSRG. 138-
1 detected arsenic above its Residential PSRG.
Based on information from Sparks., DL. 2003. Environmental Soil Chemistry the concentrations of arsenic
detected are within the naturally occurring range of arsenic "Range <0.1 to 97 mg/Kg, Median 7.2 mg/Kg;
Sparks, DL. 2003.". The reported concentrations of arsenic are likely resultant from naturally occurring or
anthropogenic sources, and not related to the historic use of the site.
Soil samples 137-1, 137-2, and DUP-2 (duplicate of sample 132-2) detected multiple VOCs and one SVOC
(naphthalene) above their respective Protection of Groundwater PSRGs. The VOC concentration of
naphthalene was above its respective Residential PSRG in the three samples and above its Industrial
Commercial PSRG in samples 137-1 and 137-2. Additionally, 1,2,4-trimethyl benzene was detected above its
Residential and Protection of Groundwater PSRGs. Arsenic and hexavalent chromium were detected
above their respective Residential PSRGs. Soil sample 137-2 and DUP-2 also contained concentrations of
selenium above its respective Protection of Groundwater PSRG.
Other targeted compounds were not detected in soil samples collected above their respective Protection
of Groundwater, Residential or Industrial/Commercial PSRGs.

A summary of the soil sample analytical results is included as Table 2, and the laboratory reports are
included as Appendix B.
Quality Control
Five duplicate soil samples (DUP-1 through DUP-5) were collected as a duplicates of the soil samples and
analyzed for VOCs using EPA Method 8260, SVOCs using EPA Method 8270, and RCRA metals using EPA
Method 6020/7471 plus Cr VI using EPA Method 7199, respectively. The compounds detected in the
duplicate samples were similar to those detected in the primary samples, except for DUP-2. DUP-2
(duplicate of soil sample 132-2) contained detections of several VOCs and one SVOC (naphthalene) that
were not present in the primary sample. Additionally, selenium was detected at a higher level in DUP-2.
The results of DUP-2 will be considered representative of cell 2 from 5 feet to the termination depth, not
the results of sample 132-2. A Level II QA/QC package was requested from the laboratory. A summary of
these analytical results is included as Table 2, and the laboratory reports are included as Appendix B.
Work Plan Deviations
The approved work plan for this project included Cr VI analysis of six of the fifteen proposed soil quality
samples. Analysis of Cr VI was to be reserved for the six samples with the highest total chromium
concentration. However, analysis of Cr VI was inadvertently included for each of the fifteen soil quality
samples. The additional data has been summarized in this report.
6.0 CONCLUSIONS
Based on the results of the soil sampling conducted for the site, ECS has the following conclusions:
• Laboratory results of the soil samples collected at the site identified multiple targeted VOCs at
concentrations above their laboratory method detection limits (MDLs) in each soil sample. Benzene
was detected above its Protection of Groundwater PSRG in soil sample 65-1. Soil samples 137-1, 67-2,
and DUP-2 (duplicate of sample 132-2) detected multiple VOCs above their respective Protection of
Groundwater PSRGs. The VOC concentrations of naphthalene was above its respective Residential
PSRG in the three samples and above its Industrial Commercial PSRG in samples 137-1 and 137-2.
Additionally, 1,2,4-trymethyl benzene was detected above its Residential and Protection of
Groundwater PSRGs.
• Laboratory results of the soil samples collected at the site identified multiple targeted SVOCs at
concentrations above their laboratory MDLs in each soil sample except 131-1, 63-1, 64-1, and 138-1
where targeted SVOCs were not detected above laboratory MDLs. Benzo(a)pyrene was detected at
a concentration exceeding its Protection of Groundwater and Residential PSRGs in soil sample 135-1.
Naphthalene was detected at concentrations above its respective Protection of Groundwater and
Residential PSRGs in soil sample DUP-2 and above its Protection of Groundwater PSRG in soil samples
137-1 and 137-2.
• Various metals were detected at concentrations above their laboratory MDLs in each soil sample.

With the exception of arsenic and hexavalent chromium, RCRA metals were not reported with
concentrations above their respective Residential PSRGs. Arsenic was detected at concentrations
exceeding the Residential PSRG in each soil sample and was detected as exceeding its
Industrial/Commercial PSRG in soil samples 61-1, 63-2, 64-1, 135-1, and 136-1. While the
concentrations of arsenic in the soil samples were greater than its PSRGs, they are within the naturally
occurring range of arsenic (Range <0.1 to 97 mg/kg, Median 7.2 mg/Kg; Sparks, DL. 2003.
Environmental Soil Chemistry). Hexavalent chromium was detected at a concentration exceeding the
Residential PSRG in soil samples 61-1, 132-1, 132-2, 133-2, 135-1, 135-2, 136-1, 136-2, 137-1, 137-2, and 138-2.
The laboratory reporting limit for hexavalent chromium for the remaining soil samples were below
the Residential PSRG of 0.31 mg/Kg.
7.0 RECOMMENDATIONS
Based on the current redevelopment plans, the site will include an inground parking garage with ground
floors to be utilized for commercial purposes and upper floors to be utilized for residential purposes. ECS
recommends utilizing this assessment's data to support drafting the Brownfields Agreement for the site, as
well as to support drafting of an Environmental Management Plan (EMP) for the proposed site
redevelopment activity. Additional assessment to determine site conditions and to facilitate Brownfields
redevelopment does not appear to be warranted at this time.
Soils
• Based on this assessment's findings, the apparent limited distribution of VOC and SVOC detections,
and reported detections of arsenic, indicative of naturally occurring background concentrations, the
soil is not expected to pose an unacceptable risk associated with redevelopment of the Peerless
Master Cleaners and Dyers site with the potential exception of the following:
➢ Soil composited from boring locations in Cell 1 0-5 feet bgs, Cell 2 from 0-6 feet bgs, Cell 3 from
5-7 feet bgs, Cell 5 from 0-11 feet bgs, Cell 6 from 0-11 feet bgs, Cell 7 0-10 feet bgs, and Cell 8
5-8.5 feet bgs indicated a reported detection of Cr VI above Residential PSRGs (Table 2). Cell 7
and Cell 5 from 0-5 feet bgs also reported one or more targeted VOC and SVOC compounds above
Residential PSRGs.
➢ Soil composited from boring locations Cell 5 from 0-5 feet bgs, and soil composited from Cell 7
from 0-10 feet bgs indicated petroleum containing soils with concentrations greater than
Residential PSRGs for one or more targeted VOC and SVOC compounds.
• Based on the results of the soil samples, it appears soils from Cell 1 from 5 — 7.5 feet, Cell 3 from 0-5
feet, Cell 4, and Cell 8 from 0-5 feet may be eligible for export to land clearing/inert debris (LCID)
landfills due to the lack of detection of targeted compounds above Residential or Industrial
Commercial PSRGs except for arsenic, indicative of naturally occurring background concentrations.
• Based on the thoroughness of the sampling protocol and the relative absence of reported soil impact
with the exception of arsenic and hexavalent chromium, ECS believes that remaining excess fill from
grading and construction activities may be beneficially re -used at NCDEQ approved off -site
commercial/industrial locations, other compatible brownfields sites, and municipal solid waste
(MSW) or construction/demolition (C&D) landfills. The scope of sampling completed in this

Notes:
Results presented in milligrams per Kilogram (mg/Kg), analogous to parts per million (ppm)
Only those constituents detected in at least one sample are listed above. For complete results, refer to laboratory report.
Sample ID: sample listed is the grab collected for VOCs only
Soil sample results are compared to the NCDEQ PSRGs dated January 2022
Highest concentration for Chromium VI reported in the lab report for each sample is shown in the table
NCDEQ= North Carolina Department of Environmental Quality
PSRG = Preliminary Soil Remediation Goal
NA= not analyzed
BMDL= Below Method Detection Limit
Bold denotes concentration equal to or in exceedance of the Protection of Groundwater PSRG
Italics denotes concentration equal to or in exceedance of the Residential Health Based PSRG
Underline denotes concentration equal to or in exceedance of the Industrial/Commercial Health Based PSRG
FLAGS:
F3 = MS and/or MSD recovery exceeds control limits
F2 = MS/MSD RPD exceeds control limits
J = Result is less than the RL but greater than or equal to the MDL and the concentration is an approximate value
Duplicate samples are representative of the following (DUP-1= B3-2, DUP-2 = 82-2, DUP-3 = B6-1, DUP-4 = 68-1, and DUP 5 = 63-1)

Narrative
Revision 1
The report being provided is a revision of the original report sent on 6/8/2022. The report (revision 1) is being revised in order to correctly
link the 7199 Hexavalent Chromium soil samples to the appropriate Method Blank in this submittal. No "B" flags should have been
assigned to the samples in this batch.
Receipt
The samples were received on 5/28/2022 10:00 AM. Unless otherwise noted below, the samples arrived in good condition, and where
required, properly preserved and on ice. The temperatures of the 3 coolers at receipt time were 1.20 C, 1.61 C and 2.21 C.
GC/MS VOA
Method 8260D: The laboratory control sample (LCS) for analytical batch 680-723858 recovered outside control limits for the following
analytes: Bromomethane. This analyte was biased high in the LCS and was not detected in the associated samples; therefore, the data
have been reported.
Method 8260D: The method blank for analytical batch 680-723858 contained Methylene Chloride above the reporting limit (RL). None of
the samples associated with this method blank contained the target compound; therefore, re -extraction and/or re -analysis of samples
were not performed.
Method 8260D: The following samples were diluted to bring the concentration of target analytes within the calibration range: B7-1
(680-216198-4), B7-2 (680-216198-5) and DUP-2 (680-216198-8). Elevated reporting limits (RLs) are provided.
Method 8260D: Surrogate recovery for the following samples were outside control limits: B7-1 (680-216198-4), B7-2 (680-216198-5) and
DUP-2 (680-216198-8). Evidence of matrix interference is present; therefore, re -extraction and/or re -analysis was not performed.
Method 8260D: The following samples were diluted to bring the concentration of target analytes within the calibration range: B7-1
(680-216198-4), B7-2 (680-216198-5) and DUP-2 (680-216198-8). Elevated reporting limits (RLs) are provided.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
GC/MS Semi VOA
Method 8270E: The matrix spike duplicate (MSD) recoveries for preparation batch 680-723746 and analytical batch 680-724136 were
outside control limits. Sample matrix interference and/or non -homogeneity are suspected because the associated laboratory control
sample (LCS) recovery was within acceptance limits.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
HPLC/IC
Per method requirements, Hexavalent Chromium soil samples are run in duplicate. The higher result is considered the primary result and
the lower result is secondary.
Metals
Method 7471 B: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for preparation batch 680-723747 and analytical batch
680-723982 were outside control limits. Sample matrix interference and/or non -homogeneity are suspected because the associated
laboratory control sample (LCS) recovery was within acceptance limits.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
