SECTION 1
INTRODUCTION
Falcon Engineering, Inc. (Falcon) herein presents this updated Environmental Site
Characterization (ESC) Report for the Town of Chapel Hill Police Department located at 828
Martin Luther King Jr. Boulevard in Chapel Hill, Orange County, North Carolina. This ESC was
conducted in general accordance with the October 2015 Inactive Hazardous Sites Program's
Guidelines for Assessment and Cleanup (Guidelines). In general, the purpose of this ESC is to
evaluate the on -site soil and groundwater for potential impacts from previously identified coal
combustion products (CCPs) located within the property boundaries. The following is a summary
of assessment activities and is not intended to replace more detailed information provided
throughout the report.
Falcon has previously installed and sampled on -site monitoring wells (MWs); however, due to the
local recharge rates and the nature of the CCPs to increase turbidity the initial wells were either
too turbid (>IONTU) or ran dry before they could be adequately purged and stabilized. New
wells were installed in proximity to the former wells but to a greater depth. Monitoring wells MW 1,
MW3A, and MW4A were re -developed using surging in February 2016 and purged after waiting
one week. The wells were sampled after chemical stability was documented; however, only
MW3A was below IONTU at the time of sampling. Both filtered and non -filtered samples were
obtained from MW 1 and MW4A. This sampling event was monitored by the North Carolina
Department of Environment and Natural Resources (DEQ) through ongoing correspondence
before and during the sampling event. A summary of groundwater analytical results is discussed
below:
• Arsenic, barium, total chromium, lead, and manganese were identified within the
groundwater at MW 1 at concentrations above their 2L Standard (the groundwater
quality standards specified in Subchapter 2L - Groundwater Classification and Standards
of 15A North Carolina Administrative Code (NCAC). Beryllium, Cobalt and vanadium
were detected at MW 1 but do not have a 2L standard. It should be noted MW 1 is
located within the area of CCP fill.
• Selenium was detected at 6pg/I above its 2L Standard of 20pg/I within the groundwater
at MW3A which is down gradient of MW l . Strontium was also detected at MW3A but
does not have a 2L Standard.

• COCs above the 2L standard or without a 2L standard were not identified in MW4A with
the exception of Strontium.
• Copper, mercury, nickel, and zinc were detected at MW1 at concentrations below the
2L standard. Barium and manganese were detected in both MW3A and MW4A below 2L
standards. Lead and zinc were also detected in MW4A below the 2L standard.
The following Table depicts COCs identified above their respective standards and their
concentrations.

Falcon also sampled the soil in the area where suspected CCPs were previously observed and
where proposed construction may take place. Soil Samples SS1, SS2, and SS3 were taken at the
fence line north of the existing greenway. Samples SS4, SS5, SS6, and SS7 were taken within the
limits of proposed construction. The Inactive Hazardous Sites Branch has two soil remediation
goals: a "health -based" remediation goal for total concentrations of contaminants, and a
"protection of groundwater" remediation goal for leachable concentrations of contaminants.
The results of the above mentioned sampling efforts are summarized below:
• Arsenic, cobalt, and manganese were above PRSRGs in all soil samples except
manganese in sample SS3.
• Vanadium, was found in all of the samples but was only slightly elevated above its PSRG
in SS1, SS1 Dup, and SS2.

1.1 Site Location and Description
The property is located at 828 Martin Luther King Jr. Blvd. in Chapel Hill, Orange County, North
Carolina. The site is located immediately southeast of the Martin Luther King Jr Blvd. intersection
with Bolinwood Drive. The Orange County GIS Website indicates the property is 10.24 acres and
corresponds to PIN 978941394. Coordinates 35055'36.56"N/-790 3'10.86"W correspond to the
approximate center of the existing structure on the property.
The northwest corner of the property is currently developed with a two-story structure
approximately 25,000 square feet in size. A few cargo containers used for storage and two
parking lots (north and south of the building) are also in this area. The remainder of the property
is wooded or landscaped lawn, with the exception of Bolin Creek and the Bolin Creek
Pedestrian Greenway. The creek flows from the west to the east along the southern border. The
greenway follows Bolin Creek along its north bank.
1.2 Current Land Use
The site is currently owned and operated by the Town of Chapel Hill. The majority of the
northwest corner of the site is used as the Chapel Hill Police Department and has been since the
town acquired the property in 1980. The southern boundary of the site includes Bolin Creek and
the Bolin Creek Pedestrian Greenway. The greenway is a paved trail through public open space
used for recreational activities such as walking, jogging, etc.

1.3 Site History and Previous Assessment
The Town of Chapel Hill previously retained Falcon to perform environmental consultation at the
property. Previous consultation includes, but is not limited to; a Phase I & Limited Phase II
Environmental Site Assessment (ESA), A Remedial Investigation Work Plan, and earlier phases of
this Remedial Investigation/Environmental Site Characterization Report. Additional details are
provided in Table No. 3 below:

Falcon was originally retained by the Town of Chapel Hill to perform Environmental due
diligence in July 2013. During the performance of the combined Phase I and Limited Phase II ESA
it became apparent that fill materials were previously placed adjacent to a steep slope along
the southern portion of the property. Falcon confirmed the historic use of the site as a borrow pit
in the late 1950's through early 1960's then as a fill site from the mid-1960's to mid-1970's. Falcon
installed two ground water monitoring wells (MW1 and MW2) and obtained two soil samples (S1
and S4). Sample S-1 was obtained using a geoprobe during the installation of MW-1 at a depth
of 15 feet below existing ground surface. S-4 was obtained through Hand Auger techniques at a
depth of approximately 1 foot below ground surface. Sample S1 was analyzed for diesel range
organics (DRO) only. DRO was identified in S1 but was below the regulatory action limit of 10
mg/kg. Arsenic, cadmium, chromium, cobalt, copper, iron, manganese and DRO (27mg/kg)
were detected in S-4 above their respective soil to groundwater Maximum Soil Contamination
Concentrations (MSCCs). Groundwater Sample MW1 exhibited levels of arsenic, barium,
chromium, cobalt, iron, and manganese above the 2L standard. Groundwater Sample MW2
showed levels of barium, chromium, cobalt, copper, iron, manganese, thallium, and zinc above
the standard. A Summary of the 2013 Limited Phase II ESA soil and groundwater analytical results
is presented in Table 8 found in Appendix A. A Sample location map is provided in A.
Falcon mobilized to the site in March of 2014 to begin Initial Remedial Investigation and
determine the nature and extent of potentially contaminated soils. Falcon performed composite
Town of Chapel Hill Police Department 7 April 1, 2016
Environmental Site Characterization Report Project No.: E16002

soil sampling at three locations (S5, S6, & S7). Sample locations were placed in areas observed to
be potentially exposed CCP along the face of the steep slope. The samples were taken by hand
auger and consisted of 4.0 feet of material just below removed leaf litter. Analytical analysis of
the composite soil samples confirmed the presence of barium and chromium above the NC
DEQ Soil to Groundwater Maximum Soil Contamination Concentration (MSCCs). Only Barium
was reported to be above the NC DEQ Residential MSCCs on a few samples. A sample location
map is included in Appendix A. Table 9 Summary of 2014 Composite Soil Sampling Analytical
Results above Method Detection is included in Appendix A.
Falcon also contracted Troxler Geologic to mobilize a geoprobe to the site in March 2014. Troxler
Geologic utilized direct push technology to install two monitoring wells (MW3 and MW4) and to
sample the soil at greater depths. Falcon established a sampling grid across the area of
suspected fill to delineate the presence or absence of disposed CCPs. A visual depiction of
these sampling locations can be found in Appendix A of this report. Laboratory analysis of the
groundwater sampled from MW4 indicated levels of mercury, arsenic, barium, chromium, lead
and selenium above 2L Groundwater Standard. Groundwater collected and analyzed from
MW-3 indicated concentrations of Barium within the sample, but below the NC DENR 2L
Groundwater Standard. Table 10 Summary of 2014 MW3 and MW4 Groundwater analytical
Results is included in Appendix A. Laboratory analysis of the geoprobe samples indicated levels
of mercury, arsenic, barium, chromium, lead and selenium above their MSCCs. Table 11
Summary of 2014 Geoprobe Soil Sample Analytical Results is included in Appendix A.
A summary of 2014 geoprobe collected soil composition data is included in Appendix A as Table
12. This table includes location ID, final probed depths and approximate depths to which CCPs
may be present. It should be noted that due to the consistency of CCPs, the material being
compacted can give inaccurate portrayals of the depths of these materials. Falcon used its best
judgment in determining the vertical extents of the material based on ease of drilling, recoveries,
and site characteristics/gradient. It should also be noted that in some locations a layering of ash
followed by a debris material or fill then back into an ash layer was observed. Field logs and
pictures are provided in the Appendix for a more detailed description.
Falcon also sampled the surface water upstream and downstream of the site during the initial
Remedial Investigation. Surface water sampled from Bolin Creek did not exhibit results indicative
of environmental contamination above established INC DENR Surface Water Standards for water
supply sources or freshwater aquatic life.
Town of Chapel Hill Police Department 8 April 1, 2016

In response to the Initial Remedial Investigation the Town of Chapel Hill installed a chain -link
fence between the greenway and the downslope side of the steep slope where CCPs were
observed In order to prevent material from leaving the site and to protect the public from
coming in contact with CCPs. The fence is gated and secured with a padlock to deter access.
In addition, two rows of silt fence were installed to mitigate future CCP exposure. One silt fence
was installed immediately south of the pile to prevent further run-off from the pile. The second silt
fence runs the length of the chain -link fence in an effort to restrict surface material from entering
Bolin Creek.
Based upon the results of the initial Remedial Investigation, DEQ requested a Remedial Work
Plan to identify other potential releases of hazardous substances, characterize the chemical
nature of such releases, and collect sufficient sampling data to compile a list of contaminates of
concern (COCs). The work plan was submitted to and approved by DEQ in April 2015. It was
determined that MW3 and MW4 should be abandoned and two new monitoring wells (MW3A
and MW4A) be installed within the same general locations but to a deeper depth in an effort to
obtain less turbid samples.
Falcon installed and sampled MW3A and MW4A in May and July of 2015; however, the wells
remained turbid. DEQ requested redeveloping the wells in an effort to obtain less turbid samples
and provided an updated list of COCs specific to this site in an email dated January 13, 2015.
The updated list targets parameters that pose an environmental and/or human health risk and
have a regulatory standard (with the exception of strontium and molybdenum). The current list
of COCs for all media as provided by DEQ is included below. The results of previous site
characterization efforts are discussed throughout this report.

1.4 Current Project Objective and Scope of Work
The specific purpose of this phase of the ESC Report is to:
• Document attempts to re -develop, purge, and sample the three on -site wells (MWI,
MW3A, and MW4A) in general accordance with the previously developed Work Plan
and the Environmental Protection Agencies' Science and Ecosystem Support Division
Groundwater Sampling Procedure document dated March 6, 2013 (EPA Document).
• Sample and analyze the groundwater within the three wells and suspect soils for the
above COCs. Specifically the soils to be sampled include the area where suspected
CCPs were previously observed (between the cliff and the greenway) and where the
proposed greenway extension will be constructed.
• Survey the locations and elevations of wells and soil sample points utilizing a licensed
Professional Land Surveyor.
• Create a Water Table Elevation Contour Map based on the survey and water level data
obtained in the field. Include the survey and contour map with the report.
• Submit the Updated ESC Report including documented field activities and analytical
results to DEQ upon completion.

SECTION 2
METHODS OF INVESTIGATION
2.1 Monitoring Wells; Design, Installation, and Abandonment
Permanent monitoring wells were designed, constructed, installed, and abandoned in general
accordance with the applicable rules of NCAC 15A Subchapter 2C - Well Construction
Standards. Well Construction and Well Abandonment records are provided in Appendix C of this
report. Drill cuttings and purge water were contained to the proximity of well locations through
the use of earthen berms as needed. After installing each well, at least 24-hours was allowed for
the surface pad and protective casing to cure prior to developing the wells. A Survey of
monitoring well and soil sample locations is included in Appendix A.
Two groundwater monitoring wells were installed during the Limited Phase II ESA, a permanent
well (MW 1) and a temporary well (MW2). MW 1 was installed adjacent to the southwest corner of
the Police Station within the area of suspected fill. MW2 was installed between the subject
property and Bolin Creek. MW1 was installed By American Environmental Drilling, Inc. using
geoprobe push technology. A 2" PVC casing with 10' screen was placed to a depth of 40'
below existing ground surface (BGS). MW-2 was installed by Falcon using hand auger
techniques. A temporary casing was placed to a depth of approximately 8' BGS. MW2 was
abandoned after sampling.
Two additional groundwater monitoring wells (MW3 and MW4) were installed by Trigon
Exploration using rotary drill rigs in January 2014. MW3 was placed towards the western side of
property within the wooded area north of Bolin Creek Greenway Trail. MW4 was placed towards
the eastern side of property also within the wooded area north of Bolin Creek Greenway Trail.
The installation depth of MW3 was 1 1.0' BGS and the installation depth of MW4 was 9.2' BGS.
It should be noted that shallow depths and auger refusal were encountered during the
installation of MW3 and MW4. Initial groundwater depths were recorded at 3.4' BGS for MW3
and 4.1' BGS for MW4. This may have been due to the natural geology and proximity to Bolin
Creek. MW3 and MW4 yielded insufficient groundwater with high turbidity preventing accurate
results during subsequent sampling attempts. MW3 and MW4 were properly abandoned by
Trigon Exploration on January 6 and 7, 2015, respectively.
The installation of one additional well (MW-5) was attempted in January of 2014 to determine
background concentrations within the groundwater up -gradient from MW1. This well was
Town of Chapel Hill Police Department 1 1 April 1, 2016
Environmental Site Characterization Report

proposed to be placed on the north end of the property in the upper parking lot. Drilling was
performed at this location until continued auger refusal was achieved due to onsite geologic
conditions. Drilling completed at MW-5 at a final depth of 31.5' bgs. The augers were left for 12
hours to see if groundwater was present at these depths; however the well was observed to be
dry and as a result filled in.
Two new down gradient monitoring wells, MW3A and MW4A, were installed by American
Environmental Drilling, Inc., with rotary drill rigs between May 12 and 15, 2015. Both wells were
constructed with 2" casing. MW3A is located directly south and down gradient of the exposed
fill materials just outside of the fence north of the Bolin Creek Greenway Trail. MW4A was placed
farther southeast towards the eastern property boundary and just outside of the gate to the
fence north of the Bolin Creek Greenway Trail. The installation depth of MW3A was 16.0' BGS and
the installation depth of MW4A was 19.0' BGS. The static water level depth at time of install for
MW3A was 10.0' BGS and MW4A was 4.0' BGS. MW3A was installed with a 16' screen. MW4A was
installed with a 15' screen.
2.2 Monitoring Wells; Development and Purging
The process of drilling permanent wells has the potential to affect the hydraulic characteristics of
the surrounding soils -fines and other small particulate matter from the drilling process can remain
in the borehole. These particles can increase turbidity and block the pores of the surrounding
aquifer and/or clog the screen. Well Development is used to restore or improve hydrologic
characteristics including turbidity. MW 1 and MW2 were installed using geoprobe push
technology (not drilling) and hand auger technology respectively during preliminary due
diligence assessment; therefore, development and well stabilization was not documented
during their instillation.
MW3 and MW4 were developed on January 29-30, 2014. Per the established guidance, 24- hours
were allowed for the surface pad and protective casing to settle before developing the wells.
The method of development was by over -pumping. This method entails pumping the well at a
rate greater than in normal operation allowing water to carry small particles into the hole where
it can be pumped out. Both wells recharged following adequate purging of at least three well
volumes or the wells being purged dry. Development and well stabilization were not
documented during this phase of investigation.
MW3A and MW4A were originally developed in May and July 2015 using over pumping. This
method of development was determined inadequate as the wells remained turbid after multiple
Town of Chapel Hill Police Department 12 April 1, 2016
Environmental Site Characterization Report

vu�
well volumes were purged. In a letter dated October 23, 2015, DEQ recommended aggressive
re -development of the three remaining wells.
Falcon returned to the site in February, 2016 to re -develop MW1, MW3A, and MW4A using
surging. Surging flushes water into and out of the well through the screen removing fines and
other sediment that might clog the screen. Falcon utilized a 1.5" diameter x 2' long solid surge
block to pull loose material through the screen and into the well so it could be pumped out.
Falcon inserted the surge block into the well and quickly moved the block up and down the
length of the screen within the water column creating a plunger effect. After 10-15 minutes of
surging Falcon utilized a variable speed submersible pump to quickly remove the agitated well
water. Falcon spent approximately one day at each well alternating between surging and
pumping. MW3A became very clear by the end of the day. MW4A was significantly improved
but not as clear as MW3A. MW1 changed color from dark -grey to light -brown. The three wells
were allowed to settle for 1 week before purging.
Falcon returned after one week and began to purge the three wells and collect well
stabilization data. According to the EPA Document; "With respect to the ground water
chemistry, an adequate purge is achieved when the pH and specific conductance of the
ground water have stabilized and the turbidity has either stabilized or is below 10 Nephelometric
Turbidity Units (NTUs)" and "Stabilization occurs when, for at least three consecutive
measurements, the pH remains constant within 0.1 Standard Unit and specific conductance
varies no more than approximately 5 percent.
Falcon utilized a bladder pump for MW3A and MW4A but had to rely on a variable speed
submersible pump set at its lowest setting for MW1 due to the shallow depth of water (6.5') within
the 40' well. Prior to initiation of pumping, a properly decontaminated water level meter was
used to record the water level and monitor for a slight and stable drawdown of the water
column during purging. A Hatch 2100 Turbidity Meter and a WTW Multi -parameter Water Quality
Meter were used to monitor turbidity, specific conductivity, temperature, and pH.
According to the EPA Document; "With respect to volume, an adequate purge is normally
achieved when three to five well volumes have been removed." And "If, after three well
volumes have been removed, the chemical parameters have not stabilized according to the
above criteria, additional well volumes (up to five well volumes), should be removed. If the
parameters have not stabilized within five volumes, it is at the discretion of the project leader
whether or not to collect a sample or to continue purging.

V��
To determine the number of gallons within three well volumes, a 2" casing volume per foot
factor of 0.48 was obtained from Table 3.2.1. Well Casing Diameter Volume Factors of the EPA
Document. The following equation was used: (Total depth of water) X (0.48 - conversion to 3
well volumes in gallons) = # of gallons to purge 3 well volumes. The stabilization parameters were
documented in the field. Field notes are included within the Appendix. MW3A was sampled
immediately after it had stabilized and was below 1 ONTU.
Both MW 1 and MW4A stabilized but remained turbid after multiple well volumes were purged. It
was decided to continue to purge both MW 1 and MW3 in an attempt to reduce turbidity once
the wells were otherwise chemically stable; however, neither well produced water with low
turbidity. MW 1 's turbidity was too high to read. It is important to note that MW 1 was installed
using direct push technology directly into the suspected area of CCP fill. The soil surrounding
MW1 is mostly CCP. This well is likely to continue to produce turbid water. MW4A's turbidity
remained in the high 100's to low 200's NTU. At the direction of DEQ and in accordance with the
Guidelines both filtered and non -filtered samples were obtained from MW1 and MW4A
immediately after documenting adequate purging and stabilization for comparative results.
Field notes are included in the appendix.
2.3 Groundwater Sampling Methods
Sampling for this event was done in general accordance with the DEQ Guidance and the EPA
Document. Sampling was performed following adequate purging and after chemical
parameter stabilization criteria had been reasonably met as discussed above. Care was taken
to not cross -contaminate the wells, Wells were sampled from presumed cleanest (MW3A) to
presumed least clean (MW 1). New non -powdered vinyl gloves were donned between wells and
as needed to keep them clean.
Falcon utilized a low flow bladder pump to collect samples from MW3A and MW4A. A variable
speed submersible pump was used for MW 1 due to the shallow depth of the water column
within the 40' well. Samples were collected directly from the pump head tubing. New clean
tubing was used for each well. Pumps and monitoring equipment were scrubbed in distilled
water containing Luminox (a standard brand of phosphate -free laboratory detergent), and
rinsed with bottled water and again with de -ionized water.
Samples were collected in appropriately labeled containers provided by the laboratory and
preserved and placed on ice immediately at the time of sample collection. Chain -of -custody
Town of Chapel Hill Police Department 14 April 1, 2016
._._._ _.._.__ _.__._...__)ort

documents were filled out and kept with the samples until custody was relinquished. Rinsate, trip
blanks and one duplicate sample were utilized.
2.5 Soil Sampling Methods
Soil sampling for this event was also done in general accordance with the DEQ Guidance and
the EPA Document. Seven soils samples (SS1-SS7) were collected. On February 3, 2016
representatives of DEQ met with a representative of The Town of Chapel Hill and Falcon onsite to
discuss the Town's proposed Bolin Creek Greenway construction project and to determine if the
greenway project will have any effect on this site. DEQ requested sampling the soil where both
the suspected CCP was observed and the greenway is proposed to be constructed. The
locations for soil samples SS1-SS3 were flagged that day along the south side of the chain link
fence where suspected CCP was observed. Flagged locations where approved by DEQ in the
field. Soil samples SS4-SS7 were flagged south of the existing greenway within the construction
limits of the prosed extension to the existing greenway in February. These sample locations were
approved by DEQ through email conversations prior to sampling.
To avoid cross contamination, new, clean, non -powdered vinyl gloves were worn while
extracting each sample. Each Sample was obtained through hand auger techniques. The hand
auger was scrubbed in distilled water containing Luminox, rinsed with bottled water and again
with de -ionized water between each sample. As directed by DEQ the top 0-2" of organic matter
was removed and excluded from the sample. Depths varied based on refusal and potential for
containing CCP. The focus was on sampling the dark soil within the top 2-12". The remaining +/-
2-12" of soil was placed in a Ziploc bag and mixed for a composite sample. Samples were
placed in appropriately labeled containers provided by the laboratory. The soil samples were
placed in an ice -filled cooler from the time they were sampled until they were picked up and
transported to the lab. Chain -of -custody documents were filled out and kept with the samples
until custody was relinquished. Rinsate, trip blanks, and one duplicate sample were utilized.
2.6 Analytical Methods
Analytical methods including laboratory quality control and quality assurance (QA/QC)
procedures for this ESC were performed by Prism Laboratories, Inc. (NC Certification No. 402).

SECTION 3
SITE GEOLOGY & HYDROLOGY
3.1 Geology
The NC Geological Survey indicates the study area is underlain by metamorphosed granitic rock
(520-650 my) - which is described as: megacrystic, well foliated, locally contains hornblende and
is fountain intrusive. The geologic age is of the Cambrian/Late Proterozoic period. The original
map label is CZg.
Falcon obtained this geologic information from the North Carolina Dept. of Environment, Health,
and Natural Resources, Division of Land Resources, NC Geological Survey, in cooperation with
the NC Center for Geographic Information and Analysis, 1998, Geology - North Carolina
(1:250,000), coverage data file geo1250. The data represents the digital equivalent of the official
State Geology map (1:500,000 scale), but was digitized from (1:250,000 scale) base maps.
3.2 Soils
The US Natural Resource Conservation Service's Orange County Soil Survey provides two (2)
different native soil types on the study area:
• TaE - Tatum Silt Loam Complex (15 to 25 percent slopes) - well drained soil derived from
red saprolite (50% of the overall study area).
WmE - Wedowee Sandy Loam Complex (15 to 25 percent slopes) - well drained soil
derived from red saprolite (50% of the overall study area).
3.3 Hydrology
A review of the Chapel Hill, NC USGS 7.5-minute 1946 topographic map, which includes the
project site, indicates that the site is located on varying elevations from 375 feet above mean
sea level (AMSL) in the northwest corner of the site to 284 feet AMSL in the southeast corner
where the site meets Bolin Creek. The 2010 Topographic Map from Orange County GIS indicates
significantly different contours from the USGS maps. This data supports the filling and leveling of
the site which would explain the soil/debris layers observed within the previously taken geoprobe
soil profiles.
The site is bounded on the north and west by paved streets, to the east by residential developed
woodlands. Bolin Creek flows west to east along the southern boundary, beyond which is
Town of Chapel Hill Police Department 17 April 1, 2016
Environmental Site Characterization Report Project No.: E16002

commercial development. The general site drainage is to the south via overland flow and along
roadside ditches. Stormwater from the study area drains toward Bolin Creek. Very little, if any,
surface water comes onto the site from offsite.
The study area and vicinity are serviced by municipal water from Orange Water and Sewer
Authority and does not currently utilize groundwater for drinking. Falcon contacted the Orange
County Health Department to request information on potable water wells registered and/or
known within the area. The closest drinking water or other potable water well is located
approximately 460 feet from the subject property. This well is located at 3 Mt Bolus Road and is
up -gradient from the subject property. Known or registered down -gradient drinking water wells
within 500 feet of property line were not reported or visually observed by Falcon staff. The closest
down -stream water supply system is Jordan Lake. The closest intake for Jordan Lake is
approximately 12.5 miles from the study area.
Groundwater flow was determined to be to the south-southeast. A water table elevation
contour map with the direction of flow is included in the appendix. Tabulated groundwater
elevation data is presented below. Water level was measured from the top of the water column
to the top of the outside casing which is equal to the ground elevation above mean sea level
(AMSL) according to the Licensed Professional Surveyor that prepared the survey. Water level
was measured using a Heron Instruments Water Level Meter (WLM). The WLM was
decontaminated between well measurements. Groundwater flow direction was determined
using a graphical three point problem and solving for the dip of the plane. Groundwater flow
was determined to be to the south-southeast based on the below data obtained February 17,
2016.

INVESTIGATION RESULTS
4.1 Groundwater Investigation Results
The 2013 Limited Phase II ESA detected arsenic, cadmium, chromium, cobalt, copper, iron,
manganese and DRO (27mg/kg) above their respective MSCCs in the on -site soils. Analysis of
groundwater from MW 1 exhibited levels of arsenic, barium, chromium, cobalt, iron, and
manganese above the 2L standard. Groundwater analyzed from MW2 showed levels of barium,
chromium, cobalt, copper, iron, manganese, thallium, and zinc above the standard. A Summary
of the 2013 Limited Phase II ESA soil and groundwater analytical results is presented in Table 8
found in Appendix A.
Previous investigative results since installing MW3A and MW4A include sampling events in May
and July of 2015. The May sampling event occurred before the wells met the chemical
stabilization criteria; therefore, the May sampling results are not an accurate indication of the
dissolved phase concentration levels of the constituents of concern. However, their results are
included below for comparison. Most COCs were not identified during the May sampling event
with the exception of the following metals: mercury, arsenic, barium, chromium, and lead.
Groundwater analytical results are presented in Table 6 below.
Falcon returned to the site in July 2015 to resample the three wells. MW3A stabilized with less
than 10 NTUs and was sampled. A duplicate sample was also obtained for MW3A. MW4A was
also stable; however, the turbidity was at 24.7 NTU. DEQ pre -approved filtered and non -filtered
samples from MW4A. MW1 was purged but did not stabilize. Turbidity remained in the mid 100
NTUs. MW 1 was not sampled in July. MW 1 was purged again on August 5 and 6, 2015 in another
effort to obtain samples from a stable well with low turbidity. However, turbidly ranged from
unreadable to the high 100 NTUs. MW 1 was not sampled in August. Groundwater analytical
results are presented in Table 6 below. Barium and Boron were detected at a concentration
below the NC DEQ 2L Groundwater Standard (2L Standard) at MW3A. Barium was detected at a
concentration below the 2L Standard at MW4A in both the filtered and unfiltered samples.
Hexavalent Chromium was not detected in either down -gradient well.
Monitoring Wells MW1, MW3A, and MW4A were sampled for the revised list of COCs on February
17 (MW3A) and 18 (MW4A and MW 1). MW3A was sampled immediately after it had stabilized
and was below 10 NTU. Both MW1 and MW4A stabilized but remained turbid after multiple well

._._._ _.._.__ _.__._...__)ort

volumes were purged. It was decided to continue to purge both MW 1 and MW3 in an attempt
to reduce turbidity once the wells were otherwise chemically stable; however, neither well
produced water with low turbidity. At the direction of DEQ and in accordance with the
Guidelines both filtered and non -filtered samples were obtained from MW 1 and MW4A
immediately after documenting adequate purging and chemical stabilization for comparative
results. The following is a summary of groundwater analytical results:
• Arsenic, barium, total chromium, lead, and manganese were identified within the
groundwater at MW 1 at concentrations above the 2L Standard. Beryllium, cobalt and
vanadium were detected at MW 1 but do not have a 2L standard.
• Selenium was detected at 6pg/I above its 2L Standard of 20pg/I within the groundwater
at MW3A. Strontium was also detected at MW3A but does not have a 2L Standard.
Strontium was below the EPA's lifetime health advisory level of 4,000 pg/I and one -day
health advisory level of 25,000pg/I.
• COCs above the 2L standard or without a 2L standard were not identified in MW4A with
the exception of Strontium which was below the EPAs health advisories.
• Copper, mercury, nickel, and zinc were detected at MWl at concentrations below the
2L standard. Barium and manganese were detected in both MW3A and MW4A below 2L
standards. Lead and zinc were also detected in MW4A below the 2L standard.
The results of the above mentioned sampling efforts are presented in Table 6 below. Table 6
depicts concentration levels and the applicable 2L Standard for the current COCs.

4.2 Soil Investigation Results
Soil investigation results from the Limited Phase II ESA in 2013 confirmed levels of arsenic,
cadmium, chromium, cobalt, copper, iron, manganese and DRO in the soil. Falcon mobilized to
the site in March of 2014 to perform composite soil sampling. Analytical analysis of the
composite soil samples confirmed the presence of barium and chromium above the NC DEQ
Soil to Groundwater MSCCs. Only Barium was reported to be above the NC DEQ Residential
MSCC on a few samples.
Falcon returned to the site on February 18, 2016 to sample the soil in the area where suspected
CCPs were previously observed (between the cliff and the greenway) and where the proposed
greenway extension will be constructed. Falcon collected eight samples (one was a duplicate).
The results of the above mentioned sampling efforts are summarized below. Table 7 depicts
concentration levels and the applicable standard for all COCs.
• Arsenic, cobalt, and manganese were above PRSRGs in all soil samples except
manganese in sample SS3.
Vanadium, was found in all of the samples but was only slightly elevated above its PSRG
in SS1, SS Dup, and SS2.

SECTION 5
CONCLUTIONS
Falcon completed an ESC Report for the Town of Chapel Hill at 828 Martin Luther King Jr.
Boulevard located in Chapel Hill, Orange County, North Carolina. The purpose of the
investigation was to evaluate the on -site groundwater for potential impacts within the property
boundaries.
Based upon our completed field activities and subsequent laboratory analysis Falcon was able
to provide the following findings:
1. Elevated levels of arsenic, barium, total chromium, lead, and manganese were
detected in the groundwater at MW 1 above the 2L Standard.
2. Selenium was detected at 6pg/I above its 2L standard within the groundwater at MW3A.
3. COCs above the 2L standard or equivalent were not identified within the groundwater at
MW4A.
4. Arsenic, cobalt, and manganese were above PRSRGs in all soil samples except
manganese in sample SS3.
5. Vanadium, was found in all of the soil samples but was only slightly elevated above its
PSRG in SS 1, SS Dup, and SS2.
SECTION 6
RECOMMENDATIONS
Falcon recommends that this report be submitted to NC DEQ for their further review to assist
them in recommending next steps. Based on the sampling results, selenium and strontium were
detected down -gradient of MW1. Selenium was reported at 26pg/I, the 2L standard is 20pg/I.
Strontium does not have a 2L or interim maximum allowable standard. NC DEQ will likely consider
the Town of Chapel Hill Police Department a low priority site. Following NC DEQ review Falcon is
available to provide additional consultation and recommended courses of action to comply
with possible next steps.

Hi Chris
As we discussed last week, the list of sample parameters for the Chapel Hill PD site has been revised. We have updated
the list to target parameters that pose an environmental and/or human health risk and have a regulatory standard. Note
that the list is specifically for laboratory analysis. All field parameters should be collected as required in our guidance.
Please see the attached list and contact me if you have any questions.
Thanks
Amy
