Brownfields Assessment Report
828 Martin Luther King Jr. Blvd. Property
Chapel Hill, North Carolina
H&H Job No. TCH-009
1.0 Introduction
On behalf of the Town of Chapel Hill (Town), Hart & Hickman, P.C. (H&H) conducted
Brownfields assessment activities at the 828 Martin Luther King Jr. Boulevard (a.k.a. Chapel
Hill Police Department) Brownfields property (Brownfields Project No. 23022-19-068) located
at 828 Martin Luther King Jr. Boulevard in Chapel Hill, Orange County, North Carolina (subject
Site or Site). The Site is comprised of one parcel of land that is approximately 10.24 acres in
size and is developed with a two-story approximately 35,000 square foot (sq ft) building located
in the north -central portion of the Site. The building and associated parking areas are currently
used for police department operations by the Town. The Site topography consists of an elevated
area where the police building and associated parking lots are located which slopes along an
embankment to the south to a lower area along Bolin Creek where the Bolin Creek Trail is
located. Area topography is indicated in Figure 1, and a Site Map with Site features, surrounding
area uses, and detailed topography is included as Figure 2.
The Town is currently evaluating potential mixed -used redevelopment options for the Site that
may include a new Municipal Services Center, office, and/or retail spaces. As part of the
evaluation process, the Town applied for entry into the North Carolina Department of
Environmental Quality (DEQ) Brownfields Program and received eligibility via a Letter of
Eligibility dated October 1, 2019. Assessment activities described in this Brownfields
Assessment Report are associated with work completed at the request of the DEQ Brownfields
Program based on potential redevelopment plans. Conceptual redevelopment plans, including
potential future building locations and stormwater infrastructure, are shown in Figure 3.
A brief summary of the Site background and prior environmental assessment activities conducted
at the Site is provided in Section 2.0 below.

2.0 Site Background
Previous assessment activities indicated that the Site was initially used as a borrow pit from the
late 1950s to early 1960s, and then was used as a fill site by a previous owner for placement of
construction debris and coal combustion products (CCPs) from the mid- 1960s to the mid- 1970s.
In the early 1980s, the Town acquired the property and constructed the current police department
building. The Site consists of an upper level where the borrow pit was located which is now
occupied by the police department building and parking areas, and a lower level adjacent to
Bolin Creek where the Bolin Creek Trail is located. The upper and lower levels are separated by
a steep embankment. The Site layout, topography, and estimated area where CCPs are present
are depicted in Figure 2.
Assessment activities were conducted at the Site from 2013 to 2020 to investigate potential
environmental impacts associated with the historical placement of structural fill containing
CCPs. The investigation activities included the collection and laboratory analysis of CCPs,
groundwater, soil, sediment, and surface water samples. Based on assessment activities, the
primary compounds of concern (COCs) detected in CCPs, shallow soil, and drainage pathway
soil are certain metals. Results of analysis of samples of CCPs indicate that arsenic, barium,
manganese, mercury, and selenium were detected above soil background levels and the DEQ
Preliminary Soil Remediation Goals (PSRGs). The most prevalent compound detected above
soil background levels and PSRGs in CCPs is arsenic.
In addition to COCs being identified in CCPs and soil, COCs have been detected in perched
water zones within the fill material. However, groundwater assessment activities identified
limited to no impacts in the underlying unconfined aquifer within and downgradient of the fill
area. Assessment activities also identified no significant impacts to stream sediment or surface
water in Bolin Creek. Additional background information and the methods and results of
previous assessment activities are provided in the following documents:

• Results of Data Gap Sampling Report, H&H, May 23, 2019; and
• Results of Post -Data Gap Assessment Report, H&H, December 1, 2020.
In 2020, interim remedial measures (IRMs) were implemented which included excavation and
off -Site disposal of soil and exposed CCPs along Bolin Creek Trail, stabilization and cover of
exposed CCPs along the embankment between the upper and lower portions of the Site, and
temporary measures to address stormwater and erosion control in the area of the embankment.
Specifically, approximately 1,004 tons of soil/CCPs at the base of the embankment and along
Bolin Creek were excavated and transported off -Site for disposal. In addition, super -silt fencing
and hydroseed were placed along the embankment, and a new stormwater diversion channel was
installed along portions of the top of the embankment to minimize the potential for future erosion
of soil/CCPs on the embankment. The interim measures are documented in an Interim Remedial
Measures Report prepared by H&H dated April 19, 2021.
Risk assessment activities performed after IRMs concluded that the Bolin Creek Trail is safe for
users. Under present conditions, CCP fill material at the Site is covered by at least 2 ft of soil
cover, with the exception of localized areas in the upper level with 1 to 2 ft of soil cover and
localized areas of CCPs along the embankment where IRMs were implemented (see Figure 2).
Based on potential future redevelopment scenarios, the Town requested that H&H perform
additional risk assessment activities to evaluate further measures recommended to address CCPs
at the Site. The risk assessment recommended the implementation of permanent measures to
address exposed CCPs along the embankment, potentially addressing isolated areas of soil
impacts if the Site is used for residential purposes, and managing CCPs through the
implementation of land use restrictions (LURs) and/or a DEQ-approved Environmental
Management Plan (EMP), which can all be implemented as part of Site redevelopment. Details
associated with the risk assessment activities are provided in a Risk Assessment Report dated
October 7, 2021.

On March 30, 2022, H&H participated in a virtual meeting with the DEQ Brownfields Program
and Town personnel to discuss potential data gaps and the scope of Brownfields assessment
activities to address potential data gaps. On June 22, 2022, H&H participated in an additional
virtual meeting with the DEQ Brownfields Program to further discuss proposed Brownfields
assessment activities. The June 22 meeting resulted in an email from DEQ requesting
assessment of perched water/groundwater, soil, soil gas, and sub -slab vapor at the Site. To
address DEQ's request for assessment at the Site, H&H submitted a Brownfields Assessment
Work Plan (Work Plan) dated July 21, 2022. Following review of the Work Plan, DEQ provided
comments in an email dated August 18, 2022. A Revised Work Plan dated August 18, 2022 was
subsequently submitted and received approval via an email dated August 30, 2022.
A summary of Brownfields assessment activities conducted in accordance with the Work Plan is
provided in the following sections.

3.0 Brownfields Assessment Activities
In August and September 2022, H&H completed Brownfields assessment activities at the Site in
accordance with the DEQ Brownfields-approved Work Plan. The activities included assessment
of soil, perched water/groundwater, sub -slab vapor, and soil gas to further evaluate potential
impacts at the Site and potential risks associated with conceptual Site redevelopment plans. In
addition, receptor survey activities were completed to obtain information about land use, water
supply, basements, underground utilities, 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. Additionally, soil boring locations were hand cleared to 5 feet below ground surface
(ft bgs) to further screen the boring locations for the presence of subsurface utilities.
The proposed Brownfields assessment activities were performed in general accordance with the
DEQ Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup
(Guidelines) dated July 2021, the DEQ Division of Waste Management (DWM) Vapor Intrusion
Guidance dated March 2018, Brownfield's Vapor Intrusion Assessment Work Plan & Report

4.0 Receptor Survey
On October 27, 2022, 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, and surface water bodies located within a 1,500-ft radius of the Site.
H&H also contacted the Orange County Department of Environmental Health to obtain
information regarding potable water supply wells located within the search radius.
In addition, H&H reviewed the online DEQ Source Water Assessment Program (SWAP)
geographic information system map to identify public water intakes in the area of the site, we
identified land use and zoning using Orange County online resources, and we identified
underground utility locations using utility mark outs completed after notification to NC 811 and
visual Site observations. The Brownfields Property Receptor Survey Form is included in
Appendix A, and a Receptor Survey Map is provided as Figure 4. The results of the receptor
survey are summarized below.
Zoning
The Site has a residential (R-2) zoning designation. The adjacent properties to the north, east,
and west are also zoned residential. The southern adjacent properties are designated
neighborhood/commercial.
Municipal Water Availability
Municipal water supplied by Orange Water and Sewer Authority (OWASA) is available to the
Site and surrounding area. OWASA sources water from Cane Creek Reservoir and University
Lake, located approximately 10 miles northwest and three miles southwest of the Site,
respectively. H&H observed municipal water meters and fire hydrants for the Site and
surrounding properties which are indicative of municipal water supply.

SMARTER EWRONMENTAL SOLUTIONS

Water Supply Wells
H&H contacted OWASA 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. One potential private
well was identified during desktop research at 3 Mt Bolus Road, which is located approximately
500 ft to the north of the Site. According to OWASA, the property address is connected to public
water and sewer. No other private or public water supply wells were identified within a
1,500-ft radius of the Site. Based on the DEQ SWAP map, the nearest public water supply wells
are located approximately three miles west of the Site. In addition, a public water intake for
OWASA is located approximately 2.5 miles west of the Site on University Lake. Bolin Creek
near the Site does not discharge to University Lake.
Surface Water Bodies
According to the DEQ Division of Water Resources North Carolina Surface Water
Classifications Map and Google Earth, Bolin Creek is the closest surface water body to the Site,
which runs along the southern property boundary of the Site. DEQ classifies Bolin Creek as a
Water Supply (WS-V) water body with a supplemental Nutrient Sensitive Water (NSW)
classification. WS-V waters are protected as water supplies which are generally upstream and
draining to Class WS-IV waters or waters used by industry to supply their employees with
drinking water or as waters formerly used as water supply. An NSW supplemental classification
is for water bodies needing additional nutrient management due to being subject to excessive
growth of microscopic or macroscopic vegetation.
Additionally, stormwater and unnamed intermittent surface runoff features were observed to the
south, west, and east of the site, which enter Bolin Creek. No other surface water bodies were
observed by H&H during the pedestrian and vehicular survey of nearby properties within the
1,500-ft radius.
Other Receptors
H&H identified three collegiate centers within the 1,500-ft radius which are denoted on the
vicinity map. The closest collegiate centers are the University of North Carolina (UNC) Highway
Safety Research Center (730 Martin Luther King Jr. Blvd), the Sheps Center for Health Services

Research (725 Martin Luther King Jr. Blvd), and the UNC Office of Human Research Ethics
(720 Martin Luther King Jr. Blvd), which are located approximately 550 ft south,
750 ft southwest, and 800 ft south from the Site, respectively. In addition, the Bolin Creek Trail
runs along Bolin Creek and near the southern property boundary. The Bolin Creek Trail is a
paved recreational trail that runs along Bolin Creek. No other land uses of interest were
identified in close proximity to 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, storm sewer, municipal water, natural gas, telephone/cable main, and
an electrical cable main adjacent to and/or on the subject Site. H&H observed multiple
residential structures with obvious basements within a 1,500-ft radius of the Site.

5.0 Soil Assessment Activities
On September 6, 2022, H&H mobilized to the Site to advance soil borings in the proposed
stormwater pond area located in the eastern portion of the Site, and in the vicinity of a diesel fuel
aboveground storage tank (AST) associated with the existing Site building. The AST is
associated with an emergency generator located in the northern portion of the Site. The locations
of the soil borings (identified as HH-12 through HH-15) in conjunction with conceptual
redevelopment plans are shown on Figure 3.
Details of the soil sampling activities and results are provided in the following sections.
5.1 Soil Sampling Methodology
H&H used a decontaminated, stainless steel hand auger to advance the borings to a depth of
approximately 5 ft bgs. Continuous soil samples were collected from the borings and logged for
lithological description and field screened for indication of potential impacts by observation for
staining, unusual odors, the presence of CCPs, and the presence of volatile organic vapors using
a calibrated photoionization detector (PID). As detailed below, CCPs were not observed in the
soil borings. The boring logs are provided in Appendix B.
Soil borings were advanced at the following locations:
• HH-12 was advanced to approximately 5 ft bgs adjacent to the east of the diesel fuel
AST. Field observations did not indicate potential impacts (i.e., absence of CCPs,
significantly elevated PID readings, staining, and/or odors). As such, a sample was
collected for laboratory analysis from the interval that exhibited the highest PID readings
(4-5 ft bgs). The sample was submitted for laboratory analysis of volatile organic
compounds (VOCs) by EPA Method 8260, semi-VOCs (SVOCs) by EPA Method 8270,
and the following metals: arsenic, barium, beryllium, cadmium, total chromium, cobalt,
copper, manganese, nickel, selenium, thallium, and vanadium by EPA Method 6020,
hexavalent chromium by EPA Method 7199, mercury by EPA 7471, and strontium by
EPA Method 6010.

SMARTER EWRONMENTAL SOLUTIONS

• HH-13 through HH-15 were advanced to approximately 5 ft bgs in the proposed
stormwater pond area. Field observations did not indicate potential impacts; therefore, a
sample was collected for laboratory analysis from the interval that exhibited the highest
PID readings (0-2 ft bgs) in each respective boring. The samples were submitted for
laboratory analysis of VOCs by EPA Method 8260, SVOCs by EPA Method 8270, and
the above metals by EPA Methods 6010/6020/ 7199/7471.
Soil samples were placed in dedicated laboratory -supplied sample containers, labeled with the
sample identification, date, and requested analysis, and placed in a laboratory -supplied cooler
with ice. The soil samples were then submitted to a North Carolina -certified laboratory, Pace
Analytical (Pace), under standard chain of custody protocols for analyses as described above.
The chain of custody is provided in the laboratory analytical report provided in Appendix C.
Investigation derived waste (IDW) generated during the assessment activities was thin -spread
on -Site in landscape islands as there was no evidence of significant impacts in the borings.
Following sampling activities at each location, the soil borings were properly abandoned with
soil cuttings and the surface was repaired similarly to pre -sampling conditions. Additionally,
each soil sample location was recorded using a hand-held global positioning system (GPS) unit.
5.2 Soil Analytical Results
A tabular summary of recent and historical soil sample analytical results for metals is presented
in Table IA. A tabular summary of recent soil sample analytical results for VOCs and SVOCs is
presented in Table 113. The laboratory analytical reports and chain -of -custody records are
provided in Appendix C. The laboratory analytical results were compared to the DEQ Protection
of Groundwater (POG) and Industrial/Commercial PSRGs dated July 2022. In addition to the
PSRGs, metals results were compared to previously calculated Site -specific Background
Screening Values (BSVs). Based on EPA guidance (EPA, 2015a, 2018a, 2018b), the BSVs for
metals in soil consist of 95% upper tolerance limits (UTLs) with 95% coverage determined using
EPA's ProUCL calculator (EPA, 2015a). Note that the Site -specific BSVs are provided in

Table 1 and are based upon the results of analysis of the background soil samples collected in
November 2016 and April 2019. A summary of the soil assessment results is provided below.
VOCs
Laboratory analytical results indicate low levels of several VOCs were detected above laboratory
method detection limits (MDLs) in each soil sample; however, none of the detected
concentrations exceed the POG or Industrial/Commercial PSRGs.
SVOCs
Laboratory analytical results indicate no SVOCs were detected above laboratory MDLs.
Site -Specific COCs (Metals)
As expected, naturally -occurring levels of Site -specific COCs were detected at concentrations
above laboratory MDLs in each soil sample; however, none of the detected concentrations
exceed Site -specific BSVs. Of the metals detected, concentrations of arsenic (up to 2.0 mg/kg),
hexavalent chromium (laboratory estimated values [i.e., "J" qualified] up to 0.583 J mg/kg),
cobalt (up to 13.1 mg/kg), and manganese (up to 368 mg/kg) are above the POG PSRGs, but are
consistent with background levels.
5.3 Direct Soil Contact Risk Evaluation
The DEQ PSRGs used for comparison to the laboratory analytical results are conservative and
based upon a target Lifetime Incremental Cancer Risk (LICR) of 1.0 x 10-6 for potential
carcinogenic effects and a Hazard Quotient (HQ) of 0.2 for potential non -carcinogenic effects.
The DEQ and EPA acceptable level for potential carcinogenic risks is a cumulative LICR of
1.0 x 10-4 or less, and the acceptable level for non -carcinogenic risks is a cumulative Hazard
Index (HI; which is the sum of the individual compound HQs) of 1.0 or less.
To further evaluate the data obtained from the recently collected soil samples HH-12 through
HH-15, H&H utilized the DEQ Risk Calculator (July 2022) to evaluate soil direct contact risks
under hypothetical "worst -case" non-residential worker use scenarios. For the hypothetical
"worst case" scenario, the highest concentration of each compound detected in any of the four

samples was input into the calculator. Because EPA and DEQ do not require remediation of
concentrations below naturally occurring background levels, in the risk calculations, H&H did
not include metals concentrations consistent with background. However, for comparison
purposes, H&H also performed the risk calculations including metals concentrations consistent
with background. Copies of the completed DEQ Risk Calculators are provided in Appendix D.
The Risk Calculator results are discussed further below.
Background Metals Concentrations Excluded
• Hypothetical worst -case soil DEQ Risk Calculator results for a non-residential worker
excluding metals concentrations consistent with background indicate a calculated
cumulative LICR of 2.1 x 10-10 and a calculated cumulative HI of 0.000012, which do not
exceed DEQ acceptable levels.
Background Metals Concentrations Included
• Hypothetical worst -case soil DEQ Risk Calculator results for a non-residential worker
including background metals concentrations indicate a calculated cumulative LICR of
7.6 x 10-7 and a calculated cumulative HI of 0.076, which do not exceed DEQ acceptable
levels.
The soil sampling data represented by samples HH-12 through HH-15 indicate acceptable risks
for non-residential workers for the soil direct contact exposure pathway.

6.0 Perched Water and Groundwater Assessment Activities
On August 30 and 31, 2022, H&H mobilized to the Site to sample the existing monitoring wells
at the Site. The existing monitoring well network includes an upgradient well (MW-5), wells
installed in perched water in the fill (MW-1, MW-IA, MW-8 and MW-9), wells downgradient
and cross -gradient of the fill area (MW-3A, MW-4A, MW-6, and MW-7), and a well in bedrock
below the fill (MW-11 D). The locations of the existing monitoring wells are depicted on Figure
3.
Details of the perched water and groundwater sampling activities and results are provided in the
following sections.
6.1 Monitoring Well Gauging
Before the sampling event, all Site monitoring wells were gauged for depth to water. A
summary of the depth to water measurements is provided in Table 2. Perched water and
groundwater elevations were generally consistent between the February 2020 and August 2022
gauging events for background well MW-5. However, other monitoring wells indicated water
elevations in August 2022 that were approximately 2 to 4 ft lower than during the February 2020
monitoring event. The lower water elevations observed in August 2022 are generally consistent
with measurements collected during the previous later summer/early fall gauging event
conducted in September 2019.
As further discussed in the December 2020 Results of Post -Data Gap Assessment Report,
rainwater that infiltrates the ground and moves downward may get trapped by low permeability
zones in the fill above the unconfined aquifer and form perched water zones. These zones are
typically laterally discontinuous and only contain thin layers of water. Some of the perched
water may seep from the edges of the perched water zone to the underlying aquifer, although the
volume of seepage is typically small, especially in comparison to the volume of water in the
underlying aquifer.

Because of the apparent presence of perched water zones in the fill materials, H&H prepared an
inferred groundwater potentiometric map for the August 2022 gauging event using the
groundwater elevation data from wells MW-3A, MW-4A, MW-5, MW-6, and MW-7 which are
not screened in the fill materials and which are installed in the underlying unconfined aquifer.
The potentiometric map is provided in Figure 5 and indicates that overall groundwater flow is to
the southeast, which is consistent with previous gauging events.
6.2 Monitoring Well Sampling
After gauging, the monitoring wells were purged to ensure that water samples obtained from the
wells were representative of perched water in the fill or underlying groundwater. Purging and
sampling of the monitoring wells were completed using low flow/low stress method in general
accordance with EPA Region IV LSASD protocol. Monitoring wells MW-3A, MW-4A, MW-5,
and MW-6 were purged and sampled using a peristaltic pump with new polyethylene tubing.
Due to depths to water greater than 25 ft, monitoring wells MW-IA, MW-7, MW-8, MW-9, and
MW-111) were purged and sampled using decontaminated bladder pumps connected to new
polyethylene tubing. Note that due to the low volume of perched water in monitoring well
MW-1, purging (and therefore sampling) of the well was not performed.
During purging, field measurements of pH, temperature, dissolved oxygen, oxidation reduction
potential, turbidity, and conductivity were collected at 3 to 5-minute intervals. The intake point
of the pump tubing was placed in the approximate mid -portion of the screened interval of each
well and groundwater was removed at a rate no greater than 200 milliliters per minute. Purging
was considered complete when water quality parameters stabilized (i.e., pH ± 0.1 SU,
conductivity varies no more than 5%, and turbidity is less than 10 Nephelometric Turbidity Units
[NTUs]). H&H was able to obtain samples with turbidity less than 10 NTUs at each monitor
well. The low flow groundwater sampling records are provided in Appendix E.
Following purging, groundwater samples were collected from Site monitoring wells using the
same low flow/low stress techniques as used during purging. Groundwater samples from the
monitoring wells were collected directly into laboratory supplied sample containers. For VOC

samples in which a peristaltic pump was used for purging, the samples for VOC analysis were
collected using the "soda straw" method to minimize volatile loss through the peristaltic pump
head. Specifically, sample tubing was removed from the well and used to fill the sample
containers by reversing the flow direction of the peristaltic pump.
After collection, the sample containers were labeled with the sample identification, date, and
requested analysis, and then placed in a laboratory supplied cooler and iced. The groundwater
samples were delivered to Pace under standard chain of custody protocols for analysis of VOCs
by EPA Method 8260 (including low level 1,4-dioxane via Selected Ion Monitoring [SIM]),
SVOCs by EPA Method 8270, hexavalent chromium by EPA Method 7199, strontium by EPA

In accordance with the DEQ-approved Work Plan, IDW water generated during the assessment
activities was placed in proximity to the on -Site monitoring well network on pervious surfaces to
allow for re -infiltration.
6.3 Perched Water and Groundwater Analytical Results
A tabular summary of recent and historical perched water and groundwater sample analytical
results is presented in Table 3, and a summary of recent and historical field geochemical
parameters is provided in Table 4. In Table 3, analytical data are compared to background
(MW-5) and to the Title 15A NCAC 02L.0202 Groundwater Standards (2L Standards) amended
on April 1, 2022. The laboratory analytical report and chain -of -custody records are provided in
Appendix C.
Some observations concerning the data from the August 2022 sampling event are provided
below:
• Laboratory analytical results indicate no VOCs or SVOCs were detected above
laboratory MDLs.
• A background level of manganese (614 micrograms per liter [[tg/L] versus 2L Standard
of 50 µg/L) was identified in the groundwater sample collected from monitoring well
MW-5. The background presence of manganese is consistent with laboratory analytical
results from the November 2016 groundwater sampling event when manganese was
detected at 580 µg/L. No other compounds were detected above the 2L Standards in
background monitoring well MW-5.
• The results of analysis of the perched water sample collected from monitoring well
MW-IA indicate the presence of arsenic (37.0 µg/L versus 2L Standard of 10 µg/L),
barium (852 µg/L versus 2L Standard of 700 µg/L), and manganese (1,380 µg/L versus
background level of 614 µg/L). The August 2022 results are generally consistent with

concentrations of arsenic, barium, and manganese identified during the September 2019
sampling event.
• The results of analysis of the perched water sample collected from monitoring well
MW-3A indicate concentrations of manganese (664 µg/L) slightly above the background
level of 614 µg/L. Manganese was not detected at concentrations above the 2L Standard
or background during previous sampling events; however, the recent detection is
generally consistent with background levels.
• The results of analysis of the perched water samples collected from monitoring wells
MW-8 and MW-9 indicate concentrations of cobalt (up to 5.3 µg/L in MW-9) and
manganese (up to 5,220 µg/L in MW-9) were detected above the 2L Standards and
background levels. The August 2022 results are consistent with concentrations identified
during the September 2019 sampling event.
• Laboratory analytical results for total dissolved solids (TDS) indicate perched water
sample concentrations above the 2L Standard of 500,000 µg/L in monitoring wells
MW-lA (774,000 µg/L), MW-3A (952,000 µg/L), and MW-9 (530,000 µg/L).
• In bedrock well MW-111) which is located below the fill adjacent to MW-9, metals
concentrations were significantly lower than those in the fill and no compounds were
detected above the 2L Standards. For example, in MW-I ID, cobalt was detected at a
laboratory -estimated concentration (0.15 J µg/L) versus a concentration of 5.3 µg/L in
MW-9. In addition, manganese was detected at 48.6 µg/L in MW-11D (below the 2L
Standard of 50 µg/L and background level of 614 µg/L) in comparison to the detection of
5,220 µg/L in MW-9.

7.0 Sub -Slab Vapor and Soil Gas Assessment Activities
On September 1 and 2, 2022, H&H conducted sub -slab vapor and soil gas assessment activities
at the Site to evaluate the potential for structural vapor intrusion into the current police building
and potential future Site structures associated with a new Municipal Services Center, office,
and/or retail spaces. As part of the assessment, seven temporary soil gas monitoring points
(SG-1 through SG-7) and two temporary sub -slab vapor monitoring points (SSV-1 and SSV-2)
were installed at the Site. Sub -slab vapor locations (represented by SSV nomenclature) and soil
gas (represented by SG nomenclature) relative to proposed redevelopment plans are depicted in
Figure 3. Details of the assessment activities and results are provided in the following sections.
7.1 Soil Gas and Sub -Slab Vapor Sampling Activities
H&H installed the soil gas monitoring points by advancing borings via a decontaminated,
stainless steel hand auger to depths of approximately 5.5 ft bgs. The soil gas points were each
installed with a 6-inch long, 0.010-inch diameter stainless steel screen that 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. Prior to the collection of the soil gas samples, the
monitoring points were allowed to equilibrate for at least 48 hours following installation.
The sub -slab gas monitoring points were installed using a Cox Colvin Vapor PinTM kit (vapor
pin). To install the vapor pins, H&H used a hammer drill equipped with a 5/8-inch diameter bit
to penetrate the concrete slab. Following borehole advancement, loose cuttings were removed
with a shop -vac to allow proper installation of the vapor pin. The vapor pin assembly
(brass sampling point and silicone sleeve) was placed and seated in the drilled hole by tapping
the assembly into place using the installation/extraction tool and a dead blow hammer. The
vapor pins were then connected to 1/4-inch Teflon® tubing to allow for the sampling procedures
described below. Prior to collection of the sub -slab vapor samples, the monitoring points were
allowed to equilibrate for at least 2 hours following installation.

SMARTER EWRONMENTAL SOLUTIONS

Following sample point equilibration and prior to sample collection, a Landtec GEM 50000
(GEM) was connected to the sample Teflon® tubing and field measurements of static and
differential pressure readings were collected from each sampling point. After pressure readings
were collected, a "shut-in" test was conducted on the sampling train and helium leak checks were
conducted at each sampling point. The purpose of the shut-in test and helium leak check are to
minimize the potential for short circuiting with ambient air during sampling. The shut-in test and
leak check are described below:
• The shut-in test was conducted by connecting the flow regulator with the vacuum gauge
to the Summa® canister and sealing the flow regulator with the laboratory provided brass
cap. Once the sampling train was "closed", the sample valve on the Summa® canister
was opened and the reading on the vacuum gauge was recorded. The Summa® canister
sample valve was then closed, and the vacuum gauge was observed to ensure no vacuum
loss occurred. Because the vacuum readings remained generally the same, the shut-in
tests were considered successful. As such, each sample train passed the shut-in test.
• Prior to soil gas and sub -slab vapor 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. A sample was then
collected from the sample tubing outside the shroud into a Tedlar bag and analyzed using
the helium gas detector. Using a syringe and three-way valve, the Teflon® sample tubing
was purged using the GEM while field measurements of pressure, oxygen, carbon
dioxide, and methane (percent by volume and percent lower explosive limit) were
concurrently collected. Note that field measurements were inadvertently not collected
from soil gas monitoring point SG-1 during the initial field data collection period. The
results of the leak check indicated that helium concentrations in the Tedlar bags were less
than 10% of the helium concentrations measured within the shrouds. As such, each
sample passed the leak test.

SMARTER EWRONMENTAL SOLUTIONS

Based on extensive discussions with the GEM manufacturer, the "static pressure" reading
reported by the GEM is collected from a pressure transducer located at the influent point where
tubing from the sampling point enters the meter. The instrument is "zeroed out" prior to
connection to the sampling point tubing, which effectively removes the atmospheric pressure
from the reading. Therefore, the "static pressure" reported by the GEM is equal to the pressure
in the sampling point minus atmospheric pressure. A positive static pressure reading reflects
subsurface pressure above atmospheric, while a negative static pressure reading reflects a
vacuum in the subsurface. The "differential pressure" reading reported by the GEM is collected
from a pressure transducer located at the effluent point for the meter and reflects the pressure
exiting the unit. The "differential pressure" reported by the GEM is typically similar to and
inverse the static pressure (i.e., positive static pressure equals negative differential pressure and
vice versa). In addition, it should be noted that the GEM's estimated accuracy as reported by the
manufacturer is +/-0.5% for methane, +/-2.0 inches of water (in H20) for static pressure, and
+/-0.7 inches of H2O for differential pressure.
Following the successful leak check, mercury vapor samples were collected from each sub -slab
vapor and soil gas monitoring point using an in -line laboratory -provided sorbent tube sampler.
An air sampling pump and a flow meter were used to collect the sample through the sample train
at a constant rate of approximately 200 milliliters per minute for no less than one hour to achieve
suitable laboratory sample detection limits. Following sample collection, the sample media was
shipped under standard chain -of -custody protocols to EMSL Analytical Inc. for analysis of
elemental mercury by the National Institute for Occupational Safety and Health (NIOSH)
Method 6009.
After completion of the mercury sampling, sub -slab vapor and soil gas samples were collected
into laboratory -supplied 1-liter batch -certified stainless steel Summa canisters connected to
inline flow controllers with laboratory -calibrated vacuum gauges. Vacuum readings on the
Summa canisters were checked prior to sampling to confirm no vacuum loss greater than 10% of
the initial recorded lab vacuum when received in the field. 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 less

than approximately 200 millimeters per minute. The intake valve on each canister was fully
opened to begin collection of the soil gas samples. The initial canister vacuums were
approximately 24.5 to 30 inches of mercury and the final canister vacuums were approximately 5
inches of mercury at the conclusion of the sampling event, per laboratory standard operating
procedures.
After sample collection, the intake valve was closed, and the regulator was disconnected from
the sample canister. The canisters were placed in laboratory -supplied shipping containers,
properly labeled, and shipped under standard chain -of -custody protocols to SGS North America
Inc. — Dayton (SGS) for analysis of VOCs by EPA Method TO-15.
After completion of the soil vapor VOC sample collection, H&H capped the points for a
minimum of at least four hours prior to the collection of a final round of methane, carbon
dioxide, oxygen, and pressure measurements. Upon completion of the assessment activities, soil
gas monitoring point locations were surveyed using a hand-held GPS unit. Sub -slab vapor
monitoring point locations were estimated based upon referencing distances to building
landmarks. At the request of the Police Department due to the planned reorganization of the
interior spaces, the sub -slab gas monitoring points SSV-1 and SSV-2 were abandoned on,
November 28, 2022. Following DEQ's concurrence with the conclusions and recommendations
included in this report, the soil gas monitoring points will be properly abandoned and surfaces
will be repaired to generally match pre -drilling conditions.
IDW generated during the soil gas assessment activities was thin -spread on -Site in landscape
islands as there was no evidence of significant impacts in the soil gas monitoring point borings.
Soil gas monitoring point boring logs are provided in Appendix B.
7.2 Soil Gas and Sub -Slab Vapor Analytical Results

output obtained from the GEM and field documentation are provided in Appendix F. Sub -slab
vapor and soil gas sample analytical results were compared to the July 2022 DEQ
Non -Residential Vapor Intrusion Sub -slab and Exterior Soil Gas Screening Levels (SGSLs). A
summary of the vapor intrusion assessment results is provided below.
VOCs
Laboratory analytical results indicate that VOCs were detected above laboratory MDLs in each
sub -slab vapor and soil gas sample; however, concentrations were below the Non -Residential
SGSLs.
Mercury
Laboratory analytical results indicate that mercury was not detected at concentrations above the
laboratory MDL (<0.50 micrograms per cubic meter [µg/m3]) in sub -slab vapor or soil gas
samples collected from the Site.
Methane and Pressure Screening Results
Results of the methane gas screening activities indicate detectable concentrations of methane
only in soil gas monitoring point SG-3, which is located in the central portion of the parking lot
to the south of the police building. Methane detections in this monitoring point were 0.1 % and
0.2% (by volume). As previously mentioned, the accuracy of the GEM is +/— 0.5% for methane;
therefore, the detections are within the accuracy range of the meter. The detections in SG-3 are
also below threshold criteria in accordance with DEQ Brownfields Threshold Criteria for
Methane Site Development (December 2020) for commercial land use. Based on the detections
of methane in SG-3 below the accuracy limits of the meter which are also below the DEQ
Brownfields methane criteria for commercial buildings, and the absence of detectable methane at
other sub -slab vapor and soil gas locations, these detections do not indicate a significant methane
concern at the Site.

Remedial Services/Brownfields Documents/Brownfields Assessment Report/Final to Client/text.doc
SMARTER EWRONMENTAL SOLUTIONS

The static pressure measured in the sub -slab vapor and soil gas monitoring points ranged from
—0.3 to 0.24 in H2O. As previously mentioned, the accuracy of the GEM is +/— 2 in H2O for static
pressure. As such, the static pressure readings are below the accuracy limits of the instrument
and considered negligible.
7.3 DEQ Risk Calculations
The DEQ SGSLs are conservative and based on a LICR for potential carcinogenic risks of 1.0 x
10-6 and a non -carcinogenic HQ of 0.2 for potential non -carcinogenic risks. The DEQ and EPA
acceptable risk range for potential carcinogenic risks is 1.0 x 10-4 to 1.0 x 10-6 or less and the
acceptable level for non -carcinogenic risks is a HI less than 1.0.
H&H utilized the July 2022 DEQ risk calculator (based on the potential future uses at the Site) to
evaluate hypothetical "worst -case" scenario calculated cumulative risks for the soil gas to indoor
air vapor intrusion pathway for detected VOCs in the soil gas and sub -slab vapor samples. For
the hypothetical "worst case" scenario, the highest concentration of each compound detected in
any of the soil gas or sub -slab vapor samples was input into the calculator. Results of the risk
calculations are summarized in Table 5 and included in Appendix D.
In summary, hypothetical worst -case DEQ Risk Calculator soil gas to indoor air risk results for a
non-residential worker indicate a calculated cumulative LICR of 1.5 x 10"6 and a calculated
cumulative HI of 0.077, which do not exceed DEQ acceptable levels. Based on soil gas and sub -
slab vapor samples collected from the Site, there does not appear to be an unacceptable vapor
intrusion risk to current or future Site non-residential users.

SMARTER EWRONMENTAL SOLUTIONS

8.0 Quality Assurance/Quality Control Samples
Non -dedicated equipment and tools were decontaminated prior to use at each boring or sampling
location or following exposure to soil, soil gas, sub -slab gas, and/or groundwater samples.
Decontamination of non -dedicated equipment followed U.S. EPA Region IV guidance
(LSASDPROC-205-R4) and consisted of wiping the equipment clean, a water -rinse of the
equipment, washing the equipment in water and detergent (i.e., Liquinox® or Luminoxft and a
final rinse with water. The process was repeated for grossly contaminated non -dedicated
equipment.
For quality assurance and quality control purposes (QA/QC), and to evaluate the reproducibility
of the sample results, H&H collected the following field QA/QC samples: one duplicate soil
sample (HH-14); one duplicate perched water sample (MW-8); and one duplicate soil gas sample
(SG-7). The duplicate samples were submitted for the same laboratory analysis as their
respective parent samples. A summary of the duplicate laboratory analytical results is provided
below.
• The results of duplicate analyses for soil sample HH-14 indicate low levels of VOCs and
naturally -occurring levels of Site -specific COCs were detected at concentrations well
below the POG, Industrial/Commercial PSRGs, and/or Site -specific BSVs (for metals).
No SVOCs were detected above laboratory MDLs in either sample. A comparison of the
soil parent and duplicate sample results generally indicates good analytical repeatability.
• The results of duplicate analyses for perched water sample MW-8 indicate concentrations
of cobalt (2.7 µg/L for both the parent and duplicate samples) and manganese
(3,610 µg/L [parent]; 3,720 µg/L [duplicate]) were detected above the 2L Standards and
background levels. Others metals were detected in the parent and duplicate samples at
concentrations below the 2L Standards and/or background levels. No VOCs or SVOCs
were detected above laboratory MDLs in either sample. A comparison of the perched
water parent and duplicate sample results generally indicates good analytical
repeatability.

SMARTER EWRONMENTAL SOLUTIONS

• The results of duplicate analyses for soil gas sample SG-7 indicate several VOCs were
detected at concentrations below the Non -Residential SGSLs. A comparison of the soil
gas parent and duplicate sample results generally indicates good analytical repeatability
for most compounds.
One laboratory -provided trip blank sample was included for every cooler/shipment containing
groundwater samples for VOC analysis. No detections were reported in the trip blank.
Laboratory QA/QC procedures were employed to ensure appropriate sample handling and
analysis and to aid in the review and validation of the analytical data. QA/QC procedures were
conducted in accordance with the method protocols and included regular equipment
maintenance, equipment calibrations, and adherence to specific sample custody and data
management procedures. Samples were analyzed in conjunction with appropriate blanks,
laboratory duplicates, continuing calibration standards, surrogate standards, and matrix spiking
standards in accordance with approved methodologies to monitor both instrument and analyst
performance. Laboratory reporting limits for each analyte were at or below appropriate screening
criteria, where possible. Additionally, H&H requested that the laboratory include estimated
concentrations for compounds that were detected at levels above the laboratory method detection
limit, but below the laboratory reporting limit (i.e., J flags).
The laboratory analytical data report and QA package for each group of samples submitted to
and analyzed by the subcontracted laboratory are provided in an appendix to the final report.
Laboratory QA data consistent with Level II documentation was requested for this project. A
copy of the completed chain -of -custody record and shipping receipt was appended to the
corresponding laboratory analytical report included with the final report. The conclusions of the
data review are that field and laboratory data generally meet QA objectives and are usable for the
intended purpose.

9.0 Conclusions and Recommendations
H&H has completed Brownfields assessment activities at the 828 Martin Luther King, Jr. Blvd.
(a.k.a. Chapel Hill Police Department) Brownfields property located in Chapel Hill, North
Carolina. The assessment activities were conducted in accordance with the DEQ Brownfields-
approved Assessment Work Plan dated August 18, 2022. Brownfields assessment activities
included the collection of soil, perched water and groundwater, soil gas, and sub -slab vapor
samples to further evaluate potential impacts at the Site and potential risks associated with
conceptual Site redevelopment plans. In addition, a receptor survey was performed to obtain
information about land use, water supply, basements, underground utilities, and surface water
bodies in the Site vicinity. A brief summary of the results of the Brownfields assessment
activities is provided below.
• Results of soil assessment activities for the proposed stormwater pond area (HH-13
through HH-15) and existing diesel fuel AST (1111-12) indicate low levels of several
VOCs were detected above laboratory MDLs in each soil sample; however, none of the
detected concentrations exceed the POG or Industrial/Commercial PSRGs. In addition,
no SVOCs were detected above laboratory MDLs. As expected, naturally -occurring
levels of Site -specific COCs were detected at concentrations above laboratory MDLs in
each soil sample; however, none of the detected concentrations exceed Site -specific
BSVs and as such, are consistent with background levels.
DEQ Risk Calculator results using the data from samples HH-12 through HH-15 indicate
acceptable risks for non-residential workers for the soil direct contact exposure pathway.
• Results of recent and/or historically collected geologic data, groundwater elevation data,
and groundwater geochemical data indicate that there are perched water zones in the fill
material and that water samples collected from shallow wells in the fill are monitoring
these perched zones. Consistent with previous sampling events, elevated concentrations
of metals in groundwater samples collected in August 2022 are associated with the
presence of CCPs within or near perched water. There is limited or no groundwater

impact in monitoring wells that are screened in non -fill zones in the unconfined aquifer
located directly below the fill (MW-11D) and shallow downgradient monitoring wells
which are located downgradient of the fill area (MW-3A and MW-4A).
No VOCs or SVOCs were detected above laboratory MDLs in the on -Site monitoring
wells screened in the perched water or underlying groundwater zones.
• Results of vapor intrusion assessment activities indicate no VOCs were detected at
concentrations above the Non -Residential SGSLs. To further evaluate potential vapor
intrusion risks for the existing and potential future Site building(s), H&H utilized the
DEQ Risk Calculator to evaluate hypothetical worst -case potential vapor intrusion risks
for the soil gas to indoor air pathway under a non-residential use scenario. Calculated
cumulative risks for current and/or future non-residential workers are within the
acceptable carcinogenic risk of less than 1.0 x 10"4 and less than a hazard index of 1.0.
As such, there does not appear to be an unacceptable vapor intrusion risk to current or
future Site non-residential users.
• Results of the methane gas screening activities indicate low (0.1% and 0.2% by volume)
detections of methane in soil gas monitoring point SG-3, which is located in the central
portion of the parking lot to the south of the police building. Based on detections below
the accuracy limits of the meter, which are also below DEQ Brownfields' methane
threshold criteria for commercial land use, and the absence of detectable methane at other
sub -slab vapor and soil gas locations, these detections are not considered indicative of a
significant methane concern at the Site. In addition, static pressure measured in the sub -
slab vapor and soil gas monitoring points are below the accuracy limits of the instrument
and considered negligible.
Based upon the results, additional assessment does not appear warranted to evaluate risks
associated with proposed redevelopment activities. Impacted media or media disturbed during
future redevelopment activities can be managed in accordance with a DEQ Brownfields-
approved Environmental Management Plan (EMP) and/or land use restrictions as outlined in a
negotiated Brownfields Agreement.

Notes:
Concentrations reported in milligrams per kilogram (mg/kg).
Yellow highlighting indicates samples collected as part of September 2022 sampling.
1) Site -Specific Background Screening Value (BSV) represents 95% upper threshold level (UTL) with 95% coverage calculated using EPA ProUCL 5.1.
*Insufficient data to calculate 95% UTL; therefore, site -specific BSV indicates 2x mean concentration with non -detect concentrations calculated as half the reporting limit.
2) North Carolina Department of Environmental Quality (DEQ) Preliminary Soil Remediation Goals (PSRGs) (July 2022)
3) Duplicate sample results.
Concentrations reported in milligrams per kilogram (mg/kg).
Bold indicates concentration above or equal to Protection of Groundwater PSRG and site -specific BSV.
Shading indicates concentration above or equal to Industrial/Commercial PSRG and site -specific BSV.
CCPs = Coal Combustion Products
ND = Not Detected; NA = Not Analyzed; NS = Not Specified; NC = Not Calculated
-- = Statistical test not applicable to data set
J = Detected above method detection limit but below laboratory reporting limit; therefore, result is an estimated concentration.
01 = Analyte failed the method required serial dilution test and/or subsequent post -spike criteria. These failures indicate matrix interference.
J6 = The sample matrix interfered with the ability to make any accurate determination; spike value is low.
BH = Method blank greater than one-half laboratory reporting limit, but sample concentration greater than 10x the method blank.
A = Continuing Calibration Verification standard recovery (82%) is less than the lower control limit (90 % ). Result has possible low bias.
Excavated sample locations are not shown in table.

Notes:
Yellow highlighting indicates samples collected as part of August 2022 groundwater sampling
Concentrations reported in micrograms per liter (pg/L), except turbidity which is reported in Nephelometric Turbidity Units (NTUs).
2L Standard = North Carolina Department of Environmental Quality (DEQ) 15A NCAC 02L.0202 Groundwater Standards (April 2022).
Bold and Shading indicates concentration above or equal to the 2L Standard and background levels
NO
=Not Detected; NA=Not Analyzed; NS = Not Specified; BDL =Below Laboratory Reporting Limit; - =Not Applicable
J = Detected above method detection limit but below laboratory reporting limit; therefore, result is an estimated concentration.
'Reported to the method detection limit instead of laboratory reporting limit.
1) Denotes sample labeled as "Well #1" in the lab report associated with the Limited Phase II ESA prepared by Falcon.
2) Denotes duplicate sample results.
3) Denotes sample labeled as "Well 1" in the lab report associated with the October 3, 2014 letter prepared by Falcon.
4) Denotes filtered sample.
5) An unfiltered sample was also collected from MW4 on August 20, 2014 and the results were reported in mg/kg-wet, presumably because of the high sediment load. These data are not included in this table.
6) Trivalent chromium concentrations were calculated by subtracting hexavalent chromium from total chromium concentrations.
Analytical Methods:
Metals by EPA Method 601 OC, 6020A, or 602OB
Hexavalent Chromium by EPA Method 7196A / SM3500
Mercury by 7470A/245.1
Total Dissovled Solids (TDS) by SM 2540C
Anions by EPA Method 9056A
Volatile Organic Compounds (VOCs) by EPA Method 8260D

2) Risk evaluation performed using the highest soil gas contaminant concentrations observed site -wide, which were then entered into the July 2022 DEQ Risk Calculator for determination of hypothetical "worst case" cumulative carcinogenic risk and cumulative hazard index for the non-residential
soil gas to indoor air vapor intrusion risk pathway.
Concentrations are reported in micrograms per cubic meter (pg/rn).
Compound concentrations are reported to the laboratory method detection limits.
Laboratory analytical method is shown in parentheses.
Only compounds detected in at least one sample are shown in the table above.
VOCs = volatile organic compounds; NE = not established
J = Compound was detected above the laboratory method detection limit, but below the laboratory reporting limit resulting in a laboratory estimated concentration.

Notes:
Measurements were collected by H&H using a calibrated Landtec GEM 5000 (GEM or unit).
The static pressure transducer on the GEM is located at the point where tubing from the sampling point enters the unit. The unit is zeroed out to atmospheric pressure before the tubing from the sampling point is connected. Therefore, the adjusted static pressure as reported by the GEM is the pressure in the sampling point
minus atmospheric pressure. A positive value indicates subsurface pressure greater than atmospheric pressure. The differential pressure transducer on the GEM is located at the effluent port. The adjusted differential pressure measurement on the GEM is typically similar to and inverse the static pressure measurement.
02= Oxygen; CO2 = Carbon Dioxide; CO = Carbon Monoxide; H2S = Hydrogen Sulfide
% = Percent by volume in air; ppm = parts per million in air; in Hg = inches of mercury; in H2O = inches of water
ft bgs = feet below ground surface

QUALIFIERS
Project: TCH-009 SOIL
Pace Project No.: 92624949
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TN -The NELAC Institute.
ANALYTE QUALIFIERS
CO Result confirmed by second analysis.
J Analyte detected below the reporting limit, therefore result is an estimate. This qualifier is also used for all TICs.
L1 Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results for this analyte in associated
samples may be biased high.
MO Matrix spike recovery and/or matrix spike duplicate recovery was outside laboratory control limits.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
ML Matrix spike recovery and/or matrix spike duplicate recovery was below laboratory control limits. Result may be biased
low.
N2 The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A
complete list of accreditations/certifications is available upon request.
v1 The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the
associated samples may have a high bias.

QUALIFIERS
Project: TCH-009
Pace Project No.: 92623225
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TN -The NELAC Institute.
ANALYTE QUALIFIERS
E Analyte concentration exceeded the calibration range. The reported result is estimated.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
P4 Sample field preservation does not meet EPA or method recommendations for this analysis.
SO Surrogate recovery outside laboratory control limits.
T3 Insufficient sample received from client to perform the analysis per EPA method requirements.
v1 The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the
associated samples may have a high bias.

QUALIFIERS
Project: TCH-009
Pace Project No.: 92623351
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TN -The NELAC Institute.
ANALYTE QUALIFIERS
E Analyte concentration exceeded the calibration range. The reported result is estimated.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
ML Matrix spike recovery and/or matrix spike duplicate recovery was below laboratory control limits. Result may be biased
low.
T3 Insufficient sample received from client to perform the analysis per EPA method requirements.
v1 The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the
associated samples may have a high bias.
