2.0 Site Background
The Site was developed as residential land dating back to at least 1903, when four residences were
identified at the Site and associated with addresses 603 S. Wilmington Street and 110, 112, and
114 E. Lenoir Street. An automotive repair shop was present on the 603 S. Wilmington Street
parcel from as early as 1914 until the parcel was redeveloped in 1953 with the current commercial
office building for use by General Baptist State Convention and affiliated organizations through
September 2020. During an unknown operational period, General Baptist State Convention used
an on -Site underground storage tank (UST) to fuel the heating system. The heating system was
converted from heating oil to natural gas at an unknown time and no knowledge or documentation
of the location of the UST or any actions to abandon, remove, drain, and/or fill -in -place the heating
oil UST were identified.
The residence associated with the former 110 E. Lenoir Street address was demolished in the early
1960s and the land was converted to a parking lot for the General Baptist State Convention facility.
In 2008, the DEQ UST Section issued a No Further Action letter for a petroleum release associated
with an unregulated non-commercial UST at the 114 E. Lenoir Street parcel. No additional
information was able to be obtained regarding the release. In 2017, the residences associated with
the 112 and 114 E. Lenoir Street parcels were relocated from the Site into the historic district off
Bloodworth Street and the properties were converted into a gravel parking lot for general
downtown Raleigh parking. A Site map referencing key features and proposed redevelopment
plans is included as Figure 2.
Adjacent and upgradient of the Site are several properties with known soil and groundwater
impacts associated with petroleum and/or chlorinated solvent compounds. Specifically, these
properties include the Charter Square facility (UST Incident No. 33585) at 501 Fayetteville Street,
two former petroleum stations and an automotive repair facility at 0 Fayetteville Street, and the
former Peerless Master Cleaners and Dryers at 10 W. South Street (Figure 2).
The Site received eligibility into the DEQ Brownfields Program via a Letter of Eligibility dated
July 2, 2020. On August 5, 2020, H&H and the Prospective Developer (PD) attended a meeting
with DEQ Brownfields personnel to discuss Site history, areas of potential environmental concern,

and proposed redevelopment plans. As requested by DEQ during the meeting, on August 13, 2020,
H&H submitted a Brownfields Assessment Work Plan (Work Plan) to conduct assessment
activities to evaluate potential impacts within the redevelopment area. The Work Plan was
approved by DEQ Brownfields in an email dated August 13, 2020.
A summary of Brownfields assessment activities is provided in the following sections.

3.0 Brownfields Assessment Activities
In August 2020, H&H completed Brownfields assessment activities at the Site in accordance with
the DEQ Brownfields approved Work Plan. The assessment activities included soil, groundwater,
and vapor intrusion assessment activities to evaluate Site conditions associated with historical on -
Site operations and off -Site impacts. In addition, receptor survey activities were completed to
obtain information about land use, water supply, basements, underground utilities, drains, and
surface water bodies in the vicinity of the Site.
Prior to conducting the field activities, H&H contacted North Carolina 811, the public utility
locator, to mark subsurface utilities located on the Site. H&H also contracted with a private utility
locator to screen proposed sample locations for subgrade utilities not marked by the public locator,
and to investigate the potential presence of the former heating oil UST and any previously
unidentified USTs. Using ground penetrating radar (GPR), the private locator did not identify any
obvious evidence of USTs at the Site. Soil boring locations were hand cleared to 5 feet (ft) below
ground surface (bgs) to further screen the boring locations for the presence of subsurface utilities.
The assessment activities were conducted in general accordance with DEQ Inactive Hazardous
Sites Branch (IHSB) Guidelines for Assessment and Cleanup (Guidelines) dated January 2020, the
DEQ Division of Waste Management (DWM) Vapor Intrusion Guidance (VI Guidance) dated
March 2018, and the most recent versions of the U.S. Environmental Protection Agency (EPA)
Region IV Science and Ecosystem Support Division (SESD) Field Branches Quality System and
Technical Procedures guidance. Investigative derived waste (IDW) generated during the
assessment activities was thin spread on -Site in accordance with DEQ IHSB Guidelines.
A summary of receptor survey results is provided in Section 4.0; details of soil assessment
activities are provided in Section 5.0; details of the groundwater assessment activities are provided
in Section 6.0; details of vapor intrusion assessment activities are provided in Section 7.0; and
summary and conclusions based on the results of the assessment activities are provided in
Section 8.0.

4.0 Receptor Survey
On August 24, 2020, H&H conducted receptor survey activities at the Site and in the nearby area.
The receptor survey included a pedestrian and vehicular survey to obtain information about land
use, potential water supply wells, basements, utility manways and chases, storm sewers, other
underground utilities, drains, and surface water bodies located within a 1,500-foot radius of the
Site. H&H also contacted the Wake County Department of Environmental Services and utilized
the online DEQ Source Water Assessment Program (SWAP) geographic information system map
to obtain information regarding potable water supply wells located within the search radius. In
addition, H&H identified land use, zoning, underground utilities using Wake County online
resources. The Brownfields Property Receptor Survey Form is included as Appendix A, and a
Receptor Survey Map is provided as Figure 3. The results of the receptor survey are summarized
below.
Zoning
The subject Site and adjacent properties to the north, east, and west are zoned as "Downtown
Mixed Use" (DX-12). The adjacent properties to the south are zoned as "Commercial Mixed Use"
(CX-4).
Municipal Water Availability
Municipal water supplied by the City of Raleigh Public Utilities Department (Raleigh Water) is
available to the Site and surrounding area. H&H did not identify sources of public drinking water
within 1,500-ft of the Site based on the DEQ SWAP geographic information system map. The
City of Raleigh and Wake County obtain their water from the Neuse River and/or Cape Fear River
basins, which includes Falls Lake, Lake Wheeler, Benson Lake, and Jordan Lake. The closest
drinking water source is an intake for Lake Wheeler and is located approximately 6.1 miles
southwest of the Site.
Service area maps are not made available by Raleigh Water; however, H&H observed municipal
water meters and fire hydrants for the Site and surrounding properties.

Water Supply Wells
H&H contacted the Wake County Department of Environmental Health and conducted a
pedestrian and vehicular survey of nearby properties to identify potential water supply wells within
a 1,500-ft radius of the Site. In addition, H&H utilized Wake County iMaps interactive property
mapping web application to identify water supply wells in the vicinity of the Site. The iMaps
application indicated four water supply wells were located within the 1,500-ft radius; however,
upon further investigation the wells identified on iMaps were determined to be groundwater
monitoring wells, not potable water supply wells. No public or private water supply wells were
identified within a 1,500-ft radius of the Site during the pedestrian and vehicular survey of the
area.
Surface Water Bodies
No surface water bodies were identified on the Site. The nearest surface water body is Chavis
Branch, which is classified by DEQ as a Class C: Nutrient Sensitive Waters (NSW) surface water
body and is located approximately 1,730 feet east of the Site. No other surface water bodies were
identified within a 1,500-ft radius of the Site.
Subsurface Structures
H&H contacted North Carolina 811, the public utility locator, to mark subsurface utilities located
on the Site and conducted a visual reconnaissance in the Site area to identify potential subsurface
structures within 100 ft of the subject Site. H&H observed evidence of subsurface utilities,
including sanitary sewer, municipal water, natural gas, electrical, and communication lines
adjacent to the subject Site. The Site's municipal water, sanitary sewer, and natural gas lines
connect to the municipal utility system at multiple access points along South Wilmington Street
and East Lenoir Street. The commercial office building at the Site has a basement, which is
estimated to be 8 ft bgs. H&H did not observe any structures with obvious basements within a
1,500-ft radius of the Site; however, real estate records indicate that multiple residences with
basements or partial basements are present in the vicinity of the Site.

5.0 Soil Assessment Activities
On August 25, 2020, H&H contracted with Regional Probing Services, Inc (RPS) to advance
two soil borings (SB-1 and SB-2) to evaluate Site conditions associated with historical on -Site
operations. In addition, one background soil sample (BG-1) was collected for laboratory analysis
in a portion of the Site that does not appear to have been affected by historical Site operations.
Soil boring locations (denoted by SB and BIG nomenclature) are depicted on Figure 4, and were
advanced in the following locations:
• within the former automotive repair shop footprint on the 603 S. Wilmington Street parcel
(SB-1);
• in the central portion of the 114 E. Lenoir Street parcel (SB-2); and
• in the southeastern portion of the Site to evaluate background conditions (BG-1).
Details of the soil sampling activities and results are provided in the following sections.
5.1 Soil Sampling Activities
RPS used a track -mounted direct -push technology (DPT) drill rig to advance soil borings to depths
ranging from approximately 5 to 37 ft bgs at the locations outlined above. Continuous soil samples
were collected from the first five feet of each boring using a decontaminated stainless -steel hand
auger or acetate lined macrocore sleeves. Soil samples were logged for lithological description
and field screened for indication of potential impacts by observation for staining, unusual odors,
and the presence of volatile organic vapors using a calibrated photoionization detector (PID).
Samples were collected from each boring location based upon field observations and field
screening. No impacts were observed during field screening activates; therefore, surficial soil
samples were collected from 1-2 ft bgs in each soil boring. Boring logs including lithologic
descriptions and field screening results are provided in Appendix B.
Soil samples selected for laboratory analysis were collected directly into laboratory supplied
sample containers labeled with the sample identification, date, time, and requested analysis and
placed in a laboratory supplied cooler with ice. Soil samples were submitted to Enthalpy

Analytical, Inc (Enthalpy), a North Carolina certified laboratory, under standard chain of custody
protocols for analysis of volatile organic compounds (VOCs) by EPA Method 8260D, semi-VOCs
(SVOCs) by EPA Method 8270E, and Resource Conservation and Recovery Act (RCRA) metals
by EPA Methods 6020/7471. For quality assurance/quality control (QA/QC) purposes, a duplicate
soil sample was collected from the SB-2 soil boring and submitted to Enthalpy for the same
analysis as the SB-2 parent soil sample. Estimated values (J-flag reporting) were requested of the
laboratory.
Following sampling activities, the soil sample locations were estimated using a hand-held global
positioning system (GPS) unit. Soil boring BG-1 was properly abandoned and the surfaces were
repaired similar to pre -drilling conditions. As further discussed in Section 6.0, temporary
monitoring wells TMW-1 and TMW-2 were installed in soil boring SB-1 and SB-2, respectively.
5.2 Soil Sampling Analytical Results
A tabular summary of soil analytical results is presented in Table 1 and the laboratory analytical
report and chain of custody records are provided in Appendix C. The laboratory analytical results
were compared to the DEQ Industrial/Commercial PSRGs dated July 2020. In addition to the
PSRGs, metals results were compared to Site -specific background levels and to background ranges
for North Carolina soils published in Elements in North American Soils authored by Dragun and
Chekiri (2005).
As expected, naturally occurring levels of several metals were detected at concentrations above
laboratory method detection limits in background soil sample BG-1. Of the metals detected,
arsenic was detected at a concentration of 7.61 milligrams per kilogram (mg/kg), which is above
the Industrial/Commercial PSRG of 3.0 mg/kg, but within published background levels for North
Carolina soils. No other metals were detected at concentrations above Industrial/Commercial
PSRGs in background soil sample BG-1.
Laboratory analytical results indicated that several metals were detected in soil samples SB-1 and
SB-2 at concentrations above laboratory method detection limits, but below Industrial/Commercial

PSRGs and/or Site -specific and published background levels and are therefore considered to be
naturally occurring.
Laboratory analytical results indicated low levels of the VOC acetone (up to 0.109 mg/kg) were
detected in soil samples SB-I and SB-2 at concentrations above the laboratory method detection
limits, but well below the Industrial/Commercial PSRG. No SVOCs were detected at
concentrations above laboratory method detection limits.

6.0 Groundwater Assessment Activities
On August 25, 2020, H&H contracted RPS to install two temporary monitoring wells (TMW-1
and TMW-2) at the Site. Groundwater samples were collected for laboratory analysis from each
temporary monitoring well to evaluate subsurface conditions associated with historical on -Site
operations and off -Site impacts. Locations of the temporary monitoring wells (denoted by TMW
nomenclature) are depicted on Figure 4, and were installed in the following areas:
• within the former automotive shop footprint on the 603 S. Wilmington Street parcel
co -located with soil boring (TMW-1); and
• in the central portion of the 114 E. Lenoir Street parcel co -located with soil boring SB-2
(TMW-2).
Details of the groundwater sampling activities and results are provided in the following sections.
6.1 Groundwater Sampling Activities
The temporary monitoring well borings were advanced using the track -mounted DPT drill rig to
advance soil borings until sufficient groundwater was encountered. Continuous soil samples were
collected from the temporary monitoring well borings and logged for lithologic description and
screened using visual and olfactory methods for obvious evidence of staining, unusual odors, and
for the presence of volatile organic vapors using a calibrated PID. Temporary monitoring wells
were constructed of 1-inch diameter PVC with 10 ft of pre -packed well screen set to bracket the
water table and 1-inch diameter PVC well casing to the ground surface. Temporary monitoring
wells were installed to depths ranging from 33 to 35 ft bgs. A filter sand pack was installed from
the bottom of each temporary well boring to approximately 2 ft above each well screen, and a
hydrated bentonite seal was then installed above the filter sand pack. A summary of well
construction and groundwater elevation information is provided in Table 2. Temporary monitoring
well boring logs and construction details are provided in Appendix B.
Following installation, the temporary monitoring wells were developed by removing a minimum
of three to five well volumes from each well and field parameters were observed to have stabilized

(pH ± 0.1 Standard Units [SU] and specific conductivity varied no more than 5%). Following well
development, temporary monitoring wells were allowed to equilibrate to static conditions and a
decontaminated electronic water level meter was used to measure the depth to the water table
relative to the ground surface. Groundwater was measured at approximately 32.50 ft bgs in
TMW-1 and 30.24 ft bgs in TMW-2. Because groundwater depths exceeded the ability to collect
groundwater samples via a peristaltic pump, groundwater samples were collected from the
temporary monitoring wells using dedicated bailers. Groundwater sampling forms completed by
sampling personnel are provided in Appendix D.
Groundwater samples were collected directly into laboratory supplied sample containers, labeled
with the sample identification, Site name, date, time, and requested analyses. The groundwater
samples were then placed in a laboratory supplied cooler with ice, and shipped under standard
chain of custody protocol to Enthalpy for analysis of VOCs by EPA Method 8260B, SVOCs by
EPA Method 8270D, and RCRA metals by EPA methods 6020/7470.
Upon completion of the groundwater assessment activities, each temporary monitoring well
location was estimated using a hand-held GPS unit. Temporary monitoring wells TMW-1 and
TMW-2 were then properly abandoned by RPS and surfaces were repaired to generally match
pre -drilling conditions. Well abandonment records are included in Appendix B.
6.2 Groundwater Sampling Analytical Results
A tabular summary of the analytical results for groundwater samples collected from the temporary
monitoring wells is presented in Table 3 and copies of the laboratory analytical report and chain
of custody records are provided in Appendix C. Groundwater data were compared to the DEQ
15A NCAC 02L .0202 Groundwater Standards (2L Standards) dated April 2013, or Interim
Maximum Allowable Concentration (IMAC) if a 2L Standard has not been established. A
summary of the groundwater assessment results is provided below.
Laboratory analytical results indicated VOCs acetone (estimated concentration of
8.61 J micrograms per liter [µg/L]) and toluene (estimated concentration of 0.59 J µg/L) were

detected in TMW-2 and TMW-1, respectively, below 2L Standards. No other VOCs and no
SVOCs were detected above laboratory method detection limits in the groundwater samples.
Laboratory analytical results indicated lead was detected in TMW-1 at a concentration of
22.0 µg/L, which is above the 2L standard of 15 µg/L. No other metals were detected in
groundwater samples above their respective 2L Standards.

7.0 Vapor Intrusion Assessment Activities
On August 26, 2020, H&H completed vapor intrusion assessment activities at the Site to evaluate
the potential for structural vapor intrusion into the proposed future building. As part of the vapor
intrusion assessment activities, two sub -slab gas monitoring points (SSGP-1 and SSGP-2) were
installed in the basement of the existing Site building at 603 S. Wilmington Street. In addition,
one soil gas monitoring point (SGP-1) was installed on the 603 S. Wilmington Street parcel and
two soil gas monitoring points (SGP-2 and SGP-3) were installed on the 112 E. Lenoir Street
parcel and on the border of the 112 and 114 E. Lenoir Street parcels. The sub -slab gas and soil
gas sample locations (denoted by SSGP and SGP nomenclature, respectively) are shown in Figure
4. Details of the vapor intrusion assessment activities and results are provided in the following
sections.
7.1 Sub -Slab Gas and Soil Gas Sampling Activities
The sub -slab gas monitoring points were installed by utilizing a hammer drill and
1 %-inch diameter drill bit to advance a pilot hole into the concrete slab to a depth of approximately
13/4 inches below the surface. A drill guide was then placed in the pilot hole, and a
5/8-inch diameter drill bit was used to advance the boring through the concrete slab. Following
concrete borehole advancement, loose concrete cuttings were removed from the boring using a
bottlebrush and vacuum with a high efficiency particulate air (HEPA) filter. A Cox -Colvin Vapor
Pin TM (vapor pin) assembly (brass sampling point and silicone sleeve) was seated in the borehole
using an installation/extraction tool and hammer. Once the vapor pin assembly was secured in the
pilot hole, 1/4-inch diameter Teflon® sample tubing was attached to the vapor pin assembly sample
port barb. Sub -slab gas monitoring points were allowed to equilibrate for at least two hours
following sample point installation and prior to sampling.
The soil gas monitoring points were installed by advancing a boring via track -mounted DPT drill
rig to a depth of approximately 8 ft bgs. At each boring, a 6-inch 0.010-inch stainless steel screen
was set at the base of the boring and connected to the ground surface with'/4-inch Teflon® tubing.
The annular space of the boring was then filled with filter sand followed by a hydrated bentonite
seal to prevent short-circuiting of air from the surface. Soil gas monitoring points were allowed
to equilibrate for at least two hours following sample point installation and prior to sampling.

Prior to sub -slab gas and soil gas sampling, H&H conducted a leak check at each sample location
by constructing a shroud around the sampling point, sampling fittings, and sampling connections,
and flooding the air within the shroud with helium gas. Helium within the shroud was monitored
using a helium gas detector. Using a syringe and three-way valve, the sample point was purged,
vapor collected outside of the shroud into a Tedlar® bag, and analyzed using the helium gas
detector to ensure that helium concentrations were less than 10% of the concentration measured
within the shroud. Each sample location passed the helium leak check.
Following successful leak checks, the sub -slab gas and soil gas samples were collected into
laboratory -supplied 1 liter stainless steel Summa canisters connected to inline flow controllers with
laboratory calibrated vacuum gauges. The flow controllers were connected to the sample tubing
at each sampling point using a brass nut and ferrule assembly to form an air -tight seal. The flow
regulators were pre-set by the laboratory to regulate the intake rate to approximately
100 millimeters per minute (mL/min). The intake valve on each canister was fully opened to begin
collection of the sub -slab gas and soil gas samples. Vacuum readings on each Summa canister
were recorded prior to and following an approximate ten-minute sampling period to ensure
adequate sample volume was collected. Per laboratory standard operating procedures, a vacuum
was maintained between three and five inches of mercury within the canisters at the conclusion of
the sampling event.
For QA/QC purposes, a duplicate soil gas sample (DUP-SGP) was collected from the SGP-1 parent
soil gas sample using a two-way "T" sampler connector which allows two samples to be collected
simultaneously from a single monitoring point.
After sample collection, the Summa canister's valves were closed prior to the regulator being
disconnected from the canister and the Summa canisters were then placed in laboratory supplied
shipping containers, properly labeled, and shipped under standard chain -of -custody protocols to
Enthalpy, a North Carolina certified laboratory, for analysis of VOCs by EPA Method TO-15. The
TO-15 analysis was conducted using method detection limits below DEQ Non -Residential

were estimated using a hand-held GPS unit and sub -slab gas monitoring point locations were
estimated by measuring from known benchmarks (e.g. doorways, walls, etc.). Sub -slab gas and
soil gas monitoring points were then properly abandoned and surfaces were repaired to generally
match pre -drilling conditions.
7.2 Sub -Slab Gas and Soil Gas Analytical Results
Results of sub -slab gas and soil gas analyses are summarized in Table 4. The laboratory analytical
report and chain of custody record are provided in Appendix C. Sub -slab gas and soil gas sample
analytical results were compared to the July 2020 DEQ Non -Residential SGSLs.
Laboratory analytical results for sub -slab gas samples collected within existing Site building at
603 S. Wilmington Street (SSGP-1 and SSGP-2) indicated VOCs were detected above laboratory
method detection limits, but below their respective Non -Residential SGSLs.
Laboratory analytical results for soil gas samples collected from the 112 and 114 E. Lenoir Street
parcels (SGP-1 through and SGP-3) indicated VOCs benzyl chloride (31.3 micrograms per cubic
meter [µg/m3] in SGP-1) and ethylbenzene (up to 525 µg/m3 in SGP-1 and SGP-3) were detected
slightly above their respective Non -Residential SGSLs of 25 µg/m3 and 490 µg/m3. No other
VOCs were detected in soil gas samples above their respective Non -Residential SGSLs.
7.3 Evaluation of Vapor Intrusion Assessment Results
The DEQ SGSLs are conservative and based on a lifetime incremental cancer risk (LICR) for
potential carcinogenic risks of 1 x 10-5 and a non -carcinogenic hazard quotient (HQ) of 0.2 for
potential non -carcinogenic harmful effects. The DEQ and EPA acceptable risk range for potential
carcinogenic risks is 1 x 10-4 to 1 x 10-6 or less and the acceptable level for non -carcinogenic risks
is a hazard index (HI) less than 1.

H&H used the latest DEQ risk calculator (July 2020) to evaluate calculated cumulative risks for
the soil gas to indoor air vapor intrusion pathway at the Site using the proposed land use of the
Site (i.e., non-residential land use scenario). H&H calculated cumulative risks for the Site based
on the highest concentration of any compound detected in any sub -slab gas or soil gas sample
collected at the Site. In addition, H&H calculated risks from each sub -slab gas and soil gas sample
location. Results of the risk calculations are summarized below, shown on Figure 6, and included
in Appendix E.

As shown in the table above, calculated cumulative risks do not exceed acceptable levels
(calculated cumulative carcinogenic risks between 1 x 10"6 1 x 10"4 and HI <1) for a non-residential
worker at the Site. Based on evaluation of the July 2020 DEQ risk calculator results, there is no
evidence of a vapor intrusion concern for the existing Site building or for the proposed Site
building, and therefore mitigation measures do not appear warranted.

8.0 Summary and Conclusions
H&H has completed Brownfields assessment activities at the General Baptist State Convention
Brownfields property located in Raleigh, North Carolina. The assessment activities were
conducted in accordance with the DEQ Brownfields approved Work Plan dated August 13, 2020.
Brownfields assessment activities included soil, groundwater, sub -slab gas, and soil gas sampling
activities to evaluate for potential impacts and to assist in management of Site media during
proposed redevelopment activities. In addition, a receptor survey was performed to obtain
information about land use, water supply, basements, underground utilities, drains, and surface
water bodies in the Site vicinity. A brief summary of the Brownfields assessment activities is
provided below.
• Evidence of the presence of current or former USTs was not identified during subsurface
investigation activities.
• Results of soil assessment activities indicate that several metals were detected above
laboratory method detection limits, but below DEQ Industrial/Commercial PSRGs and are
consistent with Site -specific and published background ranges for North Carolina soils. In
addition, VOCs and SVOCs were not detected in soil above DEQ Industrial/Commercial
PSRGs.
• Results of groundwater assessment activities indicate lead was detected above the
2L Standard in TMW-1, which is located within the former automotive repair shop
footprint. VOCs and SVOCs were not detected in groundwater samples above 2L
Standards.
• Results of vapor intrusion assessment activities indicate VOCs benzyl chloride and
ethylbenzene were detected slightly above their respective Non -Residential SGSLs. No
other VOCs were detected in sub -slab gas or soil gas samples above their respective
Non -Residential SGSLs.

SMARTER ENVIRONMENTAL SOLUTIONS

DEQ risk calculator results indicate that calculated cumulative risk values for the soil gas
to indoor air vapor intrusion pathway for a non-residential use scenario are within the
acceptable carcinogenic risk of 1 x 10-4 to 1 x 10"6 and less than a hazard index of 1.
In summary, a low level of lead was identified in groundwater at a concentration above the
2L Standard. Low levels of metals were identified in soil at concentrations below Site -specific
background levels and regulatory screening criteria. Based on these results, additional assessment
does not appear warranted and impacted media or media disturbed during future redevelopment
activities can be managed in accordance with a Brownfields Environmental Management Plan
(EMP) and/or land use restrictions as outlined in a negotiated Brownfields Agreement. In addition,
based on results of vapor intrusion assessment activities, there does not appear to be an
unacceptable vapor intrusion risk to future non-residential building occupants under the current
redevelopment plan.

End Notes:
The test results listed in this report relate only to the samples submitted to the laboratory and as received by the Laboratory.
Unless otherwise noted, the test results for solid materials are calculated on a wet weight basis. Analyses for pH, dissolved oxygen, temperature, residual chlorine and sulfite that
are performed in the laboratory do not meet NELAC requirements due to extremely short holding times. These analyses should be performed in the field. The results of field
analyses performed by the Sampler included in the Certificate of Analysis are done so at the client's request and are not included in the laboratory's fields of certification nor have
they been audited for adherence to a reference method or procedure.
The signature on the final report certifies that these results conform to all applicable NELAC standards unless otherwise specified. For a complete list of the Laboratory's NELAC
certified parameters please contact customer service.
This report shall not be reproduced except in full without the expressed and written approval of an authorized representative of Air Water & Soil Laboratories, Inc.

Custody Brent Rader received the samples on 8/26/20 after being relinquished by
Hart & Hickman -Raleigh. He then delivered the samples to Enthalpy
Analytical's Durham, NC laboratory where Alyssa Miller received them
at ambient temperature and in good condition, and logged them in. Prior
to, during, and after analysis, the samples were kept under lock with
access only to authorized personnel by Enthalpy Analytical, LLC.
Analysis The samples were analyzed for the client requested TO-15 target
compound list using the analytical procedures in EPA Method TO-15,
Determination of Volatile Organic Compounds (VOCs) In Air Collected
In Specially -Prepared Canisters And Analyzed by Gas
Chromatography/Mass Spectrometry (GUMS).
Upon receipt, the canister pressures were measured and recorded. The
cans were then pressurized and a dilution ratio was calculated for each.
See Canister and Controller Data Sheet located in the Lab QC section of
this report.
All samples were analyzed at a ten -fold analytical dilution to meet NC
residential soil gas limits with the exception of acrolein, 1,1,2-
trichloroethane and 1,2-dibromoethane.
The Agilent Technologies Model 7890A, Gas Chromatograph "Tobias"
(S/N CN10823053) was equipped with a 5973N Inert MSD (S/N
US03940689) and a Restek Rxi-624 Sil MS, 60 m x 0.32 mm x 1.8 µm
(S/N 1607896) capillary column for this analysis. All samples and
standards were introduced directly to the analyzer using an Entech
7100A Preconcentrator.
Calibration The associated BFB tunes met method acceptance criteria. The initial
calibration (T050520A-TO15) met the 30% RSD criteria. The initial
calibration verification met the 30% recovery criteria. The continuing
calibration met the 30% difference criteria. Full calibration data is
available upon request.

General Reporting Notes
The following are general reporting notes that are applicable to all Enthalpy Analytical, LLC data
reports, unless specifically noted otherwise.
• Any analysis which refers to the method as "Type" represents a planned deviation from the
reference method. For instance a Hydrogen Sulfide assay from a Tedlar bag would be labeled
as "EPA Method 16-Type" because Tedlar bags are not mentioned as one of the collection
options in EPA Method 16.
• The acronym MDL represents the Minimum Detection Limit. Below this value the laboratory
cannot determine the presence of the analyte of interest reliably.
• The acronym LOQ represents the Limit of Quantification. Below this value the laboratory
cannot quantitate the analyte of interest within the criteria of the method.
• The acronym ND following a value indicates a non -detect or analytical result below the MDL.
• The letter J in the Qualifier or Flag column in the results indicates that the value is between
the MDL and the LOQ. The laboratory can positively identify the analyte of interest as
present, but the value should be considered an estimate.
• The letter E in the Qualifier or Flag column indicates an analytical result exceeding 100% of
the highest calibration point. The associated value should be considered as an estimate.
• Sample results are presented `as measured' for single injection methodologies, or an average
value if multiple injections are made. If all injections are below the MDL, the sample is
considered non -detect and the ND value is presented. If one, but not all, are below the MDL,
the MDL value is used for any injections that are below the MDL. For example, if the MDL is
0.500 and LOQ is 1.00, and the instrument measures 0.355, 0.620, and 0.442 - the result
reported is the average of 0.500, 0.620, and 0.500 - - - i.e. 0.540 with a J flag.
• When a spike recovery (Bag Spike, Collocated Spike Train, or liquid matrix spike) is being
calculated, the native (unspiked) sample result is used in the calculations, as long as the value
is above the MDL. If a sample is ND, then 0 is used as the native amount (not the MDL
value).
• The acronym DF represents Dilution Factor. This number represents dilution of the sample
during the preparation and/or analysis process. The analytical result taken from a laboratory
instrument is multiplied by the DF to determine the final undiluted sample results.
• The addition of MS to the Sample ID represents a Matrix Spike. An aliquot of an actual
sample is spiked with a known amount of analyte so that a percent recovery value can be
determined. The MS analysis indicates what effect the sample matrix may have on the target
analyte, i.e. whether or not anything in the sample matrix interferes with the analysis of the
analyte(s).

General Reporting Notes
(continued)
• The addition of MSD to the Sample ID represents a Matrix Spike Duplicate. Prepared in the
same manner as a MS, the use of duplicate matrix spikes allows further confirmation of
laboratory quality by showing the consistency of results gained by performing the same steps
multiple times.
• The addition of LD to the Sample ID represents a Laboratory Duplicate. The analyst prepares
an additional aliquot of sample for testing and the results of the duplicate analysis are
compared to the initial result. The result should have a difference value of within 10% of the
initial result (if the results of the original analysis are greater than the LOQ).
• The addition of AD to the Sample ID represents an Alternate Dilution. The analyst prepares an
additional aliquot at a different dilution factor (usually double the initial factor). This analysis
helps confirm that no additional compound is present and coeluting or sharing absorbance with
the analyte of interest, as they would have a different response/absorbance than the analyte of
interest.
• The Sample ID LCS represents a Laboratory Control Sample. Clean matrix, similar to the
client sample matrix, prepared and analyzed by the laboratory using the same reagents, spiking
standards and procedures used for the client samples. The LCS is used to assess the control of
the laboratory's analytical system. Whenever spikes are prepared for our client projects, two
spikes are retained as LCSs. The LCSs are labeled with the associated project number and kept
in-house at the appropriate temperature conditions. When the project samples are received for
analysis, the LCSs are analyzed to confirm that the analyte could be recovered from the media,
separate from the samples which were used on the project and which may have been affected
by source matrix, sample collection, and/or sample transport.
• Significant Figures: Where the reported value is much greater than unity (1.00) in the units
expressed, the number is rounded to a whole number of units, rather than to 3 significant
figures. For example, a value of 10,456.45 ug catch is rounded to 10,456 ug. There are five
significant digits displayed, but no confidence should be placed on more than two significant
digits. In the case of small numbers, generally 3 significant figures are presented, but still only
2 should be used with confidence. Many neat materials are only certified to 3 digits, and as the
mathematically correct final result is always I digit less than all its pre -cursors - 2 significant
figures are what are most defensible.
• Manual Integration: The data systems used for processing will flag manually integrated
peaks with an "M". There are several reasons a peak may be manually integrated. These
reasons will be identified by the following two letter designations on sample chromatograms,
if provided in the report. The peak was not integrated by the software "NI", the peak was
integrated incorrectly by the software "II" or the wrong peak was integrated by the software
"WP". These codes will accompany the analyst's manual integration stamp placed next to the
compound name on the chromatogram.
