1.0 PROJECT INFORMATION

The subject property is identified by the Mecklenburg County GIS as Parcel Identification Numbers
07806401 and 07806402 and is owned by Gerrard Family LLC and Mant Properties LLC, respectively
(Figure 1). The subject property is approximately 1.64 acres in size. The on-site buildings are reported as
being constructed in 1928 and 1950 and contain approximately 18,400 and 7,000 square feet of space,
respectively. The buildings were vacant at the time of the field reconnaissance, and formerly were used
as a tire service business. The buildings consisted of offices, warehouse space, service areas, and a
basement. The remaining portions of the subject property consist of grassed and paved parking areas. ECS
previously conducted a Phase I Environmental Site Assessment (Phase I ESA) for the subject property (ECS
Project No. 49:13734, dated April 28, 2021). ECS noted the following Recognized Environmental
Conditions (RECs) in the Phase I ESA:

• ECS observed staining in the location of a former above-ground storage tank (AST) that was
associated with the former auto service operations. ECS considered the potential for the observed
staining to impact the subject property to be a REC.
• ECS observed a potential former underground hydraulic lift that appeared to have been filled. ECS
considered the potential for the apparent former underground hydraulic lift to impact the subject
property to be a REC.
• ECS considered the potential for the reported former heating oil underground storage tank (UST)
at the subject property to impact the subject property to be a REC.
• ECS considered the historical use of the subject property as a gasoline station to be a REC based
on the potential for an undocumented release to impact the subject property.
• ECS considered the historical use of the subject property for auto repair and servicing to be a REC
based on the potential for an undocumented release to impact the subject property.
• ECS considered the historical use of the subject property as a junkyard to be a REC based on the
potential for an undocumented release to impact the subject property.
• ECS considered the Leaking Underground Storage Tank (LUST) incidents at surrounding and
upgradient properties to be RECs based on documented groundwater contamination, the inferred
direction of groundwater flow toward the subject property based on surface topography, and the
potential for contaminants to migrate and impact the subject property.
• ECS considered the surrounding, upgradient dry-cleaning and historical dry-cleaning facilities to
be RECs for the subject property based on the potential for undocumented releases of drycleaning
solvents from these facilities to migrate and impact the subject property.
• ECS considered the surrounding and upgradient historical auto stations to be RECs based on the
potential for undocumented releases to migrate and impact the subject property.

Based upon the results of the Phase I ESA, ECS was requested by Daniel Realty Company, LLC to conduct
an Environmental Assessment at the site in an effort to further evaluate the potential for the identified
RECs to impact the subject property.

The results of the assessment activities were summarized in ECS’s Report of Environmental Assessment
Services (ECS Project No.: 49:13734-A) submitted on August 30, 2021. ECS collected 11 groundwater

samples (GW-1 through GW-11) and six soil samples (SB-1 through SB-6) during the assessment activities.
These sample locations are indicated on Figure 2.

The groundwater samples were submitted for laboratory analysis of volatile organic compounds (VOCs)
by EPA Method 8260 and semi-volatile organic compounds (SVOCs) by EPA Method 8270.

Review of the laboratory analytical results for the groundwater samples collected indicated
concentrations of benzene in the GW-8 and GW-9 groundwater samples greater than its North Carolina
2L Groundwater Quality Standards (NC2LGWQS) and Residential Groundwater Vapor Intrusion Screening
Level (VISL). Also, chloroform was detected in groundwater samples GW-1, GW-2, GW-3, GW-4, GW-6,
GW-7, GW-9, and GW-11 at concentrations greater than its Residential Groundwater VISL, with the
concentrations detected in the GW-3, GW-4, and GW-9 samples greater than its Non-Residential
Groundwater VISL. Concentrations of diisopropyl ether in the GW-8 groundwater sample and
naphthalene, toluene, and total xylenes in the GW-9 groundwater were detected greater than the
laboratory method reporting limits, but less than their respective NC2LGWQS and VISLs. Additional VOCs
were not indicated at concentrations greater than the laboratory method reporting limits in the eleven
groundwater samples collected. No SVOCs were detected at concentrations greater than the laboratory
method detection limits in the 11 groundwater samples collected.

Review of the laboratory analytical results for the soil samples collected indicated a total of 11 compounds
in the SS-2 soil sample at concentrations greater than the laboratory method reporting limits, with the
concentrations of benzene, 1,2-dibromoethane, methylene chloride, and naphthalene greater than their
respective Protection of Groundwater Preliminary Soil Remediation Goals (PSRGs) and Soil-to-
Groundwater Maximum Soil Contaminant Concentrations (MSCCs). In addition, methylene chloride was
also detected in the SS-1, SS-3, SS-4, and SS-5 soil samples at concentrations greater than its Protection
of Groundwater PSRG and Soil-to-Water MSCC. It should be noted that methylene chloride is a common
laboratory contaminant. Additional compounds were not detected at concentrations greater than their
respective PSRGs or MSCCs.

In light of the groundwater sample results, ECS input the laboratory analytical results of the GW-1, GW-2,
GW-3, GW-4, GW-6, GW-7, GW-9, and GW-11 groundwater samples in to the NCDEQ Risk Calculator.
Based on the results of the NCDEQ Risk Calculator, the concentrations detected in the samples did not
exceed the risk thresholds.

Based on the results of the assessment activities, ECS recommended soil vapor samples be collected in
the vicinity of these groundwater samples in order to assess if a vapor risk exists at the site.

Following a telephone conversation between Daniel Realty Company, LLC and ECS on September 1, 2021,
ECS was requested to conduct the recommended soil vapor sampling.

The results of the soil gas assessment activities were summarized in ECS’s Report of Additional Assessment
Services (ECS Project No.: 49:13734-B) submitted on September 12, 2022. ECS collected four soil gas
samples (SG-1 through SG-4) from the locations shown on Figure 2. The soil gas samples were submitted
laboratory analysis of VOCs by EPA Method TO-15.

Review of the laboratory analytical results for the soil gas samples collected indicated concentrations of
benzene in the SG-1, SG-2, and SG-4 soil gas samples and cyclohexane, heptane, and hexane in the SG-4
soil gas sample greater than their respective Residential Groundwater VISLs. The concentrations of
benzene, heptane, and hexane detected in the SG-4 soil gas sample were also greater than their respective
Non-Residential VISLs. Additional compounds were detected in each of the soil gas samples collected at
concentrations greater than the laboratory method detection limits, but less than their respective
Residential and Non-Residential VISLs.

Review of the laboratory analytical results for the soil gas samples collected indicated concentrations of
benzene in the SG-1, SG-2, and SG-4 soil gas samples and cyclohexane, heptane, and hexane in the SG-4
soil gas sample greater than their respective Residential Groundwater VISLs. In light of the soil gas sample
results, ECS input the laboratory analytical results of the SG-1, SG-2, SG-3, and SG-4 samples in to the
NCDEQ Risk Calculator. Based on the results of the NCDEQ Risk Calculator, the concentrations detected
in the SG-4 soil gas sample exceed the risk threshold for Resident classification.

A Brownfields Property Application was submitted for the property on February 28, 2023. On June 14,
2023, a Teams meeting was held with Daniel Realty Company, LLC; their environmental attorney, and ECS
where the current project status was discussed. As a Brownfields Project Manager (BPM) has not been
assigned to the project at the time of the meeting, the collection of samples that would be anticipated to
be required by the BPM were requested to be collected by Daniel Realty Company, LLC.

The current proposed development at the properties includes seven-story multi-family residential tower,
with a parking garage on a basement level and floors one and two. Commercial space, a lobby/leasing
office, and coworker spaces are also proposed for floor one. Amenity spaces are proposed for floors one
and three. The proposed layout of the first floor is shown on Figure 3. This figure also includes previously
collected sample locations, as well as the locations of samples collected during the assessment activities
discussed in this report. The first floor of the proposed layout includes approximately 11,800 square feet
of residential space and approximately 48,225 square feet of non-residential space.

2.0 SCOPE OF SERVICES

The environmental assessment included the collection and laboratory analysis of soil gas samples. Drilling
activities were conducted using a Geoprobe® Direct Push Technology (DPT) drill rig. The drilling
subcontractor used for this assessment was 3D Environmental Investigations, LLC (3D). Drilling and
sampling activities were conducted on July 21 through 27, 2023.

2.1 Utility Locate

Prior to commencing with field activities, ECS contacted North Carolina One-Call to locate/mark public
utilities at the site. Required separation distances between subsurface activities and marked utilities
(typically 30-inches) were maintained during the field activities. In addition, ECS contracted with KCI to
clear the boring areas of private utilities.

2.2 Groundwater Samples

Number and Sample Location

On July 21, 2023, ECS requested that 3D construct four permanent monitoring wells (MW-1, MW-2, MW-
3, and MW-4) at the site. Drilling activities were performed under the supervision of a North Carolina
licensed well contractor with 3D. Monitoring wells MW-1, MW-2, MW-3, and MW-4 were installed to
depths of 25 feet below ground surface (ft bgs), 25 ft bgs, 20 ft bgs, and 20 ft bgs, respectively, based on
the noted first appearance of saturated conditions. The monitoring well locations are shown on Figures
3, 4, and 5. Copies of the field notes are included in Appendix A. Boring logs including well construction
details and the well construction forms are included in Appendix B.

A licensed surveyor surveyed the vertical and horizontal position of each monitoring well on August 28,
2023. The survey data is provided in Appendix C. The elevations and construction details of each
monitoring well are provided in Table 1. Based upon the surveyed elevations of the top-of-casing of each
monitoring well and the depth to water measurements collected on July 25, 2023, the inferred
groundwater flow direction beneath the site was generally to the southwest as shown on Figure 6.

Sample Collection

The wells were allowed to stabilize prior to purging and sample collection and measurement of stabilized
depth to water. Purging was considered complete when measurement of turbidity, dissolved oxygen,
specific conductance, temperature, pH, and oxidation/reduction potential had stabilized. Samples were
collected using low-flow sampling techniques with a peristaltic pump and new dedicated tubing for each
well. The monitoring wells were sampled on July 25, 2023.

Sample Analysis

Following sample collection, sample containers were placed on ice in a cooler, maintained under COC
protocol, and delivered to Pace Analytical Services, LLC (Pace), a North Carolina certified laboratory
located in Huntersville, North Carolina, on July 26, 2023. Additionally, according to the COC and sample
receiving form attached to the laboratory report from Pace, the sample coolers arrived at the laboratory
with ice intact and the measured temperatures of each of the coolers arrived below 6° C, which is within
the EPA sample temperature range (i.e., between 0° C to 6° C). A copy of the COC is included in Appendix
D.

The groundwater samples were submitted for laboratory analysis of volatile organic compounds (VOCs) by
EPA Method 8260 and total and dissolved RCRA Metals by EPA Method 6010/7471. The laboratory
detection limits were reported at or below the applicable North Carolina 2L Groundwater Quality
Standards (NC2LGWQS) to the extent technically feasible.

For quality assurance/quality control (QA/QC) purposes, duplicate groundwater sample MW-DUP was
collected from monitoring well MW-4. The duplicate sample was submitted to the laboratory without
indications from which monitoring well it was collected. The duplicate sample was analyzed for the same
compounds as the record sample. Copies of the field sampling notes are included in Appendix A.

2.3 Soil Samples

Number and Sample Location

On July 24 and 25, 2023, ECS requested that the drilling contractor advance soil borings at 13 locations (SB-
1 to SB-13) at the locations shown on Figures 3, 4, and 5. Soil borings SB-10 and SB-13 were advanced to
depths of 10 ft bgs; soil borings SB-3, SB-4, SB-6, SB-7, SB-8, SB-9, SB-11, SB-12 were advanced to 15 ft
bgs; and soil borings SB-1, SB-2, SB-5 were advanced to depths of 20 ft bgs. Each off the soil borings were
proposed to be advanced to 20 ft bgs; however, based upon observed saturated conditions several borings
were advanced to shallower depths. These soil borings were advanced to under the supervision of a North
Carolina licensed driller with 3D using a direct push technology (DPT) type drilling rig.

Sample Collection

ECS provided a project professional to collect soils continuously from the ground surface to the
termination depth of the soil borings. The soils were collected over the length of the boring in
approximately 5-foot intervals and screened in the field by placing a portion of the soil into a resealable
plastic bag and measured for volatile organic vapors using a photoionization detector (PID) after allowing
to set for approximately 15 minutes. The remaining soils from each interval were placed into a separate
resealable container with minimal headspace and set aside in a cooler with ice for potential sampling
purposes. The soil samples to be submitted to the laboratory for analysis were collected from the separate
soils that were stored on ice rather than those which were allowed to volatilize for the collection of the
PID readings.

Based upon the results of the PID screening, the soil sample from borings SB-1, SB-8, SB-10, SB-11, SB-12,
and SB-13 were collected over the 5 to 10 ft bgs interval and from borings SB-2 through SB-7 and SB-9
were collected over the 10 to 15 ft bgs interval and were submitted for laboratory analysis. Copies of the
field sampling notes are included in Appendix A.

Boring logs for each soil boring are located in Appendix B.

Sample Analysis

Following sample collection from the resealable containers into laboratory-supplied sample containers,
the sample containers were placed on ice in a cooler, maintained under COC protocol, and delivered to
Pace on July 26, 2023. For samples that were not delivered to Pace at the end of the sample day, the ice
within the sample cooler was checked at a minimum of once daily and replaced, if necessary, until the
samples were delivered to Pace. Additionally, according to the COC and sample receiving form attached
to the laboratory report from Pace, the sample coolers arrived at the laboratory with ice intact and the
measured temperatures of all coolers arrived below 6° C, which within the EPA sample temperature range
(i.e., between 0° C to 6° C). A copy of the COC is included in Appendix D.

The soil samples were submitted for laboratory analysis of VOCs by EPA Method 8260, SVOCs by EPA
Method 8270, RCRA Metals by EPA Method 6020/7471, and hexavalent chromium by EPA Method 7199.
The laboratory detection limits were reported at or below the applicable NCDEQ Preliminary Soil

Remediation Goals (PSRGs) for residential soil and protection of groundwater to the extent technically
feasible. Concentrations detected below the laboratory reporting limit and above the laboratory method
detection limit were reported by the laboratory were flagged with a J-flag qualifier, indicating the reported
concentrations were estimates.

For QA/QC purposes, a duplicate soil sample SS-DUP was collected from the same location and interval as
soil sample SB-6. The duplicate sample was submitted to the laboratory without indications from which
soil boring it was collected. The duplicate sample was analyzed for the same compounds as the record
sample.

2.4 Exterior Soil Gas Samples

Number and Sample Location

ECS collected three exterior soil gas samples (SG-1, SG-2, and SG-3) across the site. The approximate
locations of the borings are shown on Figures 3, 4, and 5.

Soil Gas Sample Collection

On July 24, 2023, shallow soil gas sampling probes SG-1, SG-2, and SG-3 were installed to depths of 10
feet advanced by a DPT drill rig. Once a boring reached the desired depth, a dedicated Nylaflow tubing
and sampling implant were lowered to the bottom of the boring. At each sample point, approximately
one foot of clean coarse sand was placed around and above the air stone and a bentonite seal was placed
above the sand to a depth of approximately one foot bgs and hydrated. A dedicated syringe was used at
each sample location and connected to the tubing to purge the tubing and interstitial space. Three
volumes of the tubing and interstitial spacing were purged prior to sample collection.

On July 27, 2023, prior to collecting the soil gas samples, helium gas was used as a QA/QC measure to
confirm the integrity of the probe seal at each sample location. A shroud that enclosed the fittings and
sample train was placed over each newly installed vapor point and filled with helium. The sample tubing
and tracer gas tubing was placed through the shroud wall via rubber grommets. During the purging stage,
the shroud was flooded with helium via the hose placed through the shroud wall. A Model MGD-2002
Multi-Gas Leak detector was connected to the probe tube and the air stream being purged was measured
for helium. A helium concentration of less than ten percent helium detected within the shroud was
considered acceptable. During leak check activities, helium concentrations remained above 10 percent in
air by volume in the shroud at each sample point and below 10 percent of the concentration of Helium
inside of the shroud in each sample train. In addition to the leak check, a shut-in test was conducted to
assess for leaks in the fittings and regulator at each sample point. Copies of the field sampling notes are
included in Appendix A.

Following purging, each vapor point was connected to a 1-liter batch certified Summa canister, which was
used to collect the sample. The Summa canisters were fitted with a five-minute flow regulator. ECS
checked and noted the vacuum on each Summa Canister before initiating the sampling procedure. The
sampling procedure was terminated when the vacuum reading was approximately five inches of mercury.

Sample Analysis

Following sample collection, the sample containers were repackaged and shipped to H&P Mobile
Geochemistry, Inc. (H&P), a laboratory located in Carlsbad, California, and certified by the National
Environmental Laboratory Accreditation Program (NELAP) on July 28, 2023. COC protocol was utilized
throughout the collection and transport of the samples. Sample containers not immediately shipped to
H&P were maintained at ECS’s office under controlled temperature and pressure conditions. A copy of
the COC is included in Appendix D.

As previously stated, the exterior soil gas samples collected were submitted for laboratory analysis of
VOCs by EPA Method TO-15. The laboratory reporting limits were reported at or below the applicable
North Carolina Residential and Non-Residential VISLs to the extent technically feasible. Additionally,
concentrations detected below the laboratory reporting limit and above the laboratory method detection
limit were reported by the laboratory were flagged with a J-flag qualifier, indicating the reported
concentrations were estimates.

For QA/QC purposes, a duplicate exterior soil gas sample (SGDUP) was collected from the same location
as record sample SG-2 and analyzed for the same compounds as the record samples. The duplicate sample
was submitted to the laboratory without indications from which sample location it was collected. The
duplicate samples were collected by a tee connection in the sampling tubing.

2.5 Sub-Slab Soil Gas Samples

Number and Sample Location

ECS collected seven sub-slab soil gas samples from the locations shown on Figures 3, 4, and 5. The sub-
slab soil gas samples were identified as SS-1 through SS-7.

Sub-Slab Soil Gas Sample Collection

ECS installed VaporPins® using a hammer drill to penetrate through the concrete slab. Once the concrete
slab was penetrated, a new VaporPin® with a new silicon sleeve was inserted in the concrete slab in
general conformance with manufacturer’s recommendations (Vapor Pin Enterprises, Inc.). The VaporPin®
setup was allowed to equilibrate for at least 20 minutes prior to leak testing.

Prior to collecting the sub-slab soil gas samples, helium gas was used as a QA/QC measure to confirm the
integrity of the probe seal at each sample location. A shroud that encloses the fittings and sample train
was placed over each newly installed vapor point and filled with helium. The sample tubing and tracer gas
tubing was placed through the shroud wall via rubber grommets. During the purging stage, the cylinder
was flooded with helium via the hose placed through the shroud wall. A Model MGD-2002 Multi-Gas Leak
detector was connected to the probe tube and the air stream being purged was measured for helium. A
helium concentration of less than ten percent helium detected within the shroud was considered
acceptable. During leak check activities, helium concentrations remained above 10 percent in air by
volume in each shroud at each sample point and below 10 percent of the concentration of Helium inside
of the shroud in each sample train. In addition to the leak check, a shut-in test was conducted to assess

For QA/QC purposes, a duplicate sub-slab soil gas sample (SS-DUP) was collected from the same location
as the SS-2 sub-slab soil gas record sample via a tee connection in the sampling tubing. The duplicate
sample was submitted to the laboratory without indications from which sampling point it was collected.
The duplicate sample was analyzed for the same compounds as the record sample.

3.0 RESULTS

The laboratory analytical results of the groundwater, soil, and exterior and sub-slab soil gas samples
collected between July 24 and 27, 2023. Groundwater sample analytical results were compared to the
North Carolina 2L Groundwater Quality Standards (NC2LGWQS) and NCDEQ Groundwater Residential
VISLs. Soil sample analytical results were compared to the Protection of Groundwater and Residential
Preliminary Soil Remediation Goals (PSRGs). Exterior and sub-slab soil gas sample results were compared
to the NCDEQ sub-slab and exterior Residential VISLs.

3.1 Groundwater Sample Results

Review of the groundwater analytical results for the samples collected on July 25, 2023, indicated
chloroform in the MW-1 groundwater sample at a concentration greater than the laboratory method
reporting limit, but less than its NC2LGWQS and Residential VISL. Additional VOCs were not indicated at
concentrations greater than the laboratory method detection limits.

Several total and dissolved metals were detected in each of the groundwater samples collected at
concentrations greater than the laboratory method detection limits, but less than their respective
NC2LGWQS and Residential VISL, if applicable.

A summary of the previous and current groundwater analytical results is included as Table 2 and the
laboratory report is included as Appendix D.

Quality Control

Duplicate groundwater sample MW-DUP was collected as a duplicate of groundwater sample MW-4. The
duplicate groundwater sample was analyzed in the same manner as the record sample. The compounds
detected in the duplicate sample were similar to those detected in the record sample. A Level II QA/QC
package was performed by the laboratory.

The results are summarized in Table 2 and the laboratory report is included as Appendix D.

3.2 Soil Sample Results

Review of the laboratory analytical results for the samples collected on July 24, 2023, indicated one or
more VOCs in the SB-11, SB-12, and SB-13 soil samples collected at concentrations greater than the
laboratory method detection limits, but less than their respective PSRGs. VOCs were not detected at
concentrations greater than the laboratory method detection limits in the remaining soil samples
collected.

Several SVOCs were detected in the SB-2, SB-8, SB-9, SB-10, SB-11, SB-12, and SB-13 soil samples collected
at concentrations greater than the laboratory method detection limits, with the concentration of
benzo(a)pyrene detected in the SB-12 soil boring greater than its Protection of Groundwater and
Residential PSRGs. The remaining SVOCs detected were not present at concentrations greater than their
respective PSRGs. SVOCs were not detected at concentrations greater than the laboratory method
detection limits in the remaining soil samples collected.

Several metals were indicated at concentrations greater than the laboratory method detection limit in
each of the soil samples collected. Arsenic was present in the SB-5, SB-6, SB-7, SB-11, SB-12, and SB-13
soil samples collected at concentrations greater than its Residential PSRG, but less than its Protection of
Groundwater PSRG. Concentrations of hexavalent chromium were detected in the soil samples collected
from soil borings SB-1, SB-2, SB-3, SB-4, SB-6, SB-7, SB-8, and SB-9 greater than its Residential PSRG, but
less than its Protection of Groundwater PSRG. No additional metals were detected at concentrations
above PSRGs in the soil samples collected.

3.3 Exterior Soil Gas Sample Results

Review of the laboratory analytical results for the sub-slab soil gas samples collected on July 27, 2023,
indicated benzene in each of the exterior soil gas samples at concentrations greater than its Residential
VISLs. In addition, chloroform was detected in the SG-2 and SG-DUP sample at concentrations greater
than its Residential VISL. Additional compounds were detected in each of the exterior soil gas sample
collected at concentrations greater than the laboratory method detection limit, but less than their
respective Residential VISLs.

A summary of the previous and current exterior soil gas sample analytical results is included as Table 4
and the laboratory report is included as Appendix D.

Quality Control

Duplicate sub-slab soil gas sample SG-DUP was collected as a duplicate of sub-slab soil gas sample SG-2.
The duplicate sample was analyzed in the same manner as the record sample. The compounds detected
in the duplicate sample were similar to those detected in the SG-2 exterior soil gas sample. A Level II
QA/QC package was performed by the laboratory.

The results are summarized in Table 4 and the laboratory report is included as Appendix D.

3.4 Sub-Slab Soil Gas Sample Results

Review of the laboratory analytical results for the sub-slab soil gas samples collected on July 27, 2023,
indicated chloroform in sub-slab soil gas sample SS-5 at a concentration greater than its Residential VISL.
Additional compounds were detected in each sub-slab soil gas sample collected at concentrations
greater than the laboratory method detection limit, but less than their respective VISLs.

A summary of the sub-slab soil gas sample analytical results is included as Table 5 and the laboratory
report is included as Appendix D.

Quality Control

Duplicate sub-slab soil gas sample SS-DUP was collected as a duplicate of sub-slab soil gas sample SS-1.
The duplicate sample was analyzed in the same manner as the record sample. The compounds detected
in the duplicate sample were similar to those detected in the SS-1 sub-slab soil gas sample. A Level II
QA/QC package was performed by the laboratory.

The results are summarized in Table 5 and the laboratory report is included as Appendix D.

3.5 NCDEQ Risk Calculator

In light of the groundwater analytical results and exterior and sub-slab soil gas analytical results, ECS
input the highest concentration of each compound detected for both historic and current groundwater
and soil gas samples into the NCDEQ Risk Calculator for a site-wide “worst case” scenario. Based on the
results of the NCDEQ Risk Calculator, the Hazard Index for the Resident risk classification was not
exceeded for the groundwater concentrations, however, the concentrations detected in the exterior and
sub-slab soil gas samples did exceed the Hazard Index for the Resident risk classification. Output from
the results of the NCDEQ Risk Calculator are presented in Appendix E.

3.6 Brownfields Receptor Survey

ECS performed a Brownfields Receptor Survey. The results of the Brownfields Receptor Survey did not
identify any water supply wells within approximately 1,000 feet of the subject site and the site is provided
water and sewer from a municipal (Charlotte Water) source. The nearest surface water body to the
subject site is an unnamed tributary to Irwin Creek which is piped beneath the site. Underground utilities
were noted in the vicinity of the site at the locations identified on the figure included in Appendix F. The
Brownfields Receptor Survey form is also included in Appendix F.

3.7 Investigation Derived Waste

Investigation Derived Waste (IDW) generated from the soil borings and installation and sampling of the
monitoring wells (i.e., soil cuttings, development water, and purge water) were thinly spread onsite in the
vicinity of the boring locations.

4.0 CONCLUSIONS

Based on the results of the environmental assessment, ECS concludes the following:

• One VOC was detected in the MW-1 groundwater sample at a concentration greater than the
laboratory method detection limit, but less than its NC2LGWQS and Residential VISL. Additional
VOCs and SVOCs were not detected at concentrations greater than the laboratory method
detection limits in the groundwater samples collected.
• Various total and dissolved metals were detected in each of the groundwater samples collected
at concentrations greater than the laboratory method detection limits, but less than their
respective NC2LGWQS and Residential VISLs, if applicable.
• VOCs in the SB-11, SB-12, and SB-13 soil samples and SVOCs in the SB-2, SB-8, SB-9, SB-10, SB-11,
SB-12, and SB-13 soil samples were detected at concentrations greater than the laboratory
method detection limits, with the concentration of benzo(a)pyrene detected in the SB-12 soil
boring greater than its Protection of Groundwater and Residential PSRGs.
• Arsenic was present in the SB-5, SB-6, SB-7, SB-11, SB-12, and SB-13 soil samples collected at
concentrations greater than its Residential PSRG, but less than its Protection of Groundwater
PSRG. Concentrations of hexavalent chromium were detected in the soil samples collected from
soil borings SB-1, SB-2, SB-3, SB-4, SB-6, SB-7, SB-8, SB-9, and SB-10, greater than its Residential
PSRG, but less than its Protection of Groundwater PSRG.

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 EPAMethod 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.

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 EPAMethod 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.
