SECTION 1
INTRODUCTION
Falcon Engineering, Inc. (Falcon) completed an Environmental Site Characterization (ESC)
Report for the Town of Chapel Hill property located at 828 Martin Luther King Jr. Boulevard in
Chapel Hill, Orange County, North Carolina. The purpose of the investigation was to evaluate
the on -site groundwater for potential impacts from previously identified coal combustion
products (CCPs) within the property boundaries. Falcon has previously mobilized to the site in an
effort to install, purge, and sample monitoring wells. However, due to the local recharge rates
and the nature of the CCPs to increase turbidity the initial wells were either too turbid or ran dry
before they could be adequately purged and stabilized. New wells were installed to greater
depth and purged; however, due to inclement weather and time constraints the wells were
initially sampled prior to stabilizing and therefore, did not yield accurate analysis of the dissolved
phase contamination. This report discusses the initial sampling results from the reinstalled wells as
well as the successful results of additional sampling performed after the wells were purged a
second time and stabilized.
The most recent sampling activities were successful in sampling for dissolved phase constituents
through monitoring the wells for stability and sampling immediately after purging. Sampling
included the collection of three (3) groundwater samples from the two existing down gradient
monitoring wells, one un-filtered sample each from MW3A and MW4A along with filtered MW4A
samples due to the slightly elevated turbidity of 24.7 NTU in MW4A. This sampling event was
monitored by the North Carolina Department of Environment and Natural Resources (NCDENR)
through ongoing correspondence before and during the sampling event.
The following list provides the identified constituents (barium and boron) and their
concentrations. The identified contaminant's do not exceed the 15A NCAC 02L .0202
Groundwater Standards. Hexavalent Chromium was not identified in the collected samples. It
appears that the previously identified CCPs have not exceeded the groundwater standards
down gradient of the landfill within the property boundaries.
Barium - 67 Ng/L Barium - 64 pg/L Barium - 61 pg/L
Boron - 520 Ng/L BRL
BRL

The Environmental Site Characterization (ESC) was conducted in general accordance with the
January 2014 Inactive Hazardous Sites Program's Guidelines for Assessment and Cleanup. The
assessment was performed on a property with the property identification number (PIN)
9789413949. Figure 1 (Appendix A) provides a general site location map of the subject property.
An additional figure detailing sample locations is also provided in Appendix A of this report.
1.1 Site Location and Description
The evaluated property is approximately a 10.24-acre property located along Martin Luther King
Jr. Blvd. in Chapel Hill, North Carolina. The site is located to the east of Martin Luther King Jr.
Blvd., with development primarily focused in the northwest corner. The property is located
immediately north of Bolin Creek, beginning approximately 200 feet north of the centerline of
Hillsborough Street.
The property is currently developed with a 2 story structure approximately 25,000 square feet in
size. There are also two parking lots and a few cargo containers used for storage present on site.
The site is currently occupied by the Chapel Hill Police Department. The building is located in
the northwest corner, with the majority of parking in the center of the site. The eastern and
southern portions of the site are wooded.
1.2 Site History and Previous Scope of Work
The Town of Chapel Hill retained Falcon to conduct the ESC. Previous work conducted at the site
(Phase I ESA & Limited Phase II) is detailed below and was previously provided under separate
cover.
The past project goals of the Phase I were accomplished through the completion of the
following tasks:
• Review of environmental databases and lists obtained from Federal, State, and local
regulatory agencies including historic maps and directories of the site and the
surrounding areas.
• Visual inspection of the subject site, including photographic documentation of existing
conditions and notation of adjacent property use and conditions.
• Interviews with those knowledgeable of the site's history (as appropriate or required).
The past project goals of the Limited Phase II were accomplished through the completion of the
following tasks:

• Sediment and groundwater sampling to determine the existing conditions within
identified areas on the subject property. Sampling included two sediment samples and 3
water samples.
• Laboratory analyses of samples for Chemicals of Concern (COC).
• Comparison of analytical results to applicable criteria.
Based on findings of those investigations NCDENR requested the lab results from two down
gradient monitoring wells. Falcon also conducted geoprobe drilling on site to better assess the
extent of potential Coal Combustion Products (CCPs) on the subject property.
1.3 Current Project Objective and Scope of Work
The Town of Chapel Hill retained Falcon to continue efforts in completing the ESC. The purpose
of the ESC was to further delineate environmental conditions present at the site in regards to the
former use as a landfill. Previous work at the site is mentioned in the above section.
The current project goals of the ESC were accomplished through the completion of the following
tasks:
• Abandonment of the two (2) original down gradient monitoring wells that produced
highly turbid samples.
• Installation and development of two (2) new down gradient monitoring wells at
increased depths.
• Sampling groundwater to determine the existing conditions within identified areas on the
subject property.
Laboratory analyses of samples for Chemicals of Concern.
• Comparison of analytical results to applicable criteria.
1.4 Current Land Use
The subject property was generally undeveloped until the current police station was constructed
after 1980. However, as discussed in the Historical Usage section, it appears the site was used 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. The site has been the home of the Chapel Hill Police Station since the town acquired it in
1980. During the site reconnaissance, it became apparent that fill materials including some coal
combustion products (CCPs) were previously placed adjacent to a steep slope along the
southern portion of the property.

1.5 Description of Soils
The US Natural Resource Conservation Service's Orange County Soil Survey provides two (2)
different native soil types on the subject site:
• TaE - Tatum Silt Loam Complex (15 to 25 percent slopes) - well drained soil derived from
red saprolite (50% of the overall subject site).
• WmE - Wedowee Sandy Loam Complex (15 to 25 percent slopes) - well drained soil
derived from red saprolite (50% of the overall subject site).
1.6 Hydrogeologic Conditions
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 (msl) in the northwest corner of the site to 284 feet msl 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 seen.
The site is bounded on the north and west by paved streets, to the east by residential developed
woodlands and to the south by Bolin Creek. The general site drainage is to the South via
overland flow and along stormwater trenches aside Martin Luther King Jr. Blvd. Stormwater
drains from this site into Bolin Creek. Very little, if any, surface water comes onto the site from
offsite.
The property and surrounding area are serviced by municipal water from Orange Water and
Sewer Authority (OWASA) and does not currently utilize groundwater. Falcon contacted the
Orange County Health Department (OCHD) to request information on potable water wells
registered and/or known within the area. According to OCHD, 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 site property line were not reported or
visually observed by Falcon staff. The closest down -stream water supply system is Jordan Lake.
The closest public water supply intake for this lake is located approximately 12.5 miles away from
the subject property.

SECTION 2
METHODS OF INVESTIGATION
2.1 Monitoring Well Abandonment, Installation, and Development
During previous investigative efforts, three (3) groundwater monitoring wells had been installed,
MW1, MW3, and MW4. MW1 was installed within the area of fill including some CCPs adjacent
to the southwest corner of the Police Station Building. NC DENR requested the remaining two (2)
wells (MW3 and MW4) be installed down gradient of the fill. 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. It should be noted that shallow depths and auger refusal were encountered. This
may have been due to the natural geology and proximity to Bolin Creek. During previous
attempts to collect samples, MW3 and MW4 produced insufficient groundwater with high
turbidity readings that prevented accurate results. Results from these sampling activities were
provided in previously submitted reports to NC DENR.
The first phase of this investigation involved abandoning MW3 and MW4. Trigon Exploration was
contracted by Falcon to abandon the two wells on January 6 and 7, 2015, respectively. The
Well Abandonment Records are provided in Appendix C of this report
Additional phase of the investigation involved the installation of two (2) new down gradient
monitoring wells, MW3A and MW4A, on May 12 and 15, 2015, respectively. Falcon contracted
American Environmental Drilling, Inc. to complete well installation. MW3A was located directly
down gradient of the exposed fill materials just outside of the fence north of the Bolin Creek
Greenway Trail. MW4A was placed farther east towards the eastern property boundary and just
outside of the gate to the fence north of the Bolin Creek Greenway Trail. Refer to Figure 2 in
Appendix A for well locations. The installation depth of MW3A was 16.0 ft below ground surface
(bgs) and the installation depth of MW4A was 19.0 ft bgs. The static water level depth at time of
install for MW3A was 10.0 ft bgs and MW4A was 4.0 ft bgs. Drill cuttings and purge water were
contained to the proximity of well locations through the use of earthen berms as needed. The
well were constructed in accordance with 15A NCAC 02C .0100 or 15A NCAC 02C .0200 Well
Construction Standards. Well Construction records are provided in Appendix C of this report.
The wells were purged on May 21-22 and July 20-22, 2015. MW 1 was purged on Aug 5, and 6,
2015. The method of purging the wells was by low flow pumping. Per the established guidance,
After installing the wells 24- hours was allowed for the surface pad and protective casing to cure
8

prior to purging. The wells recharged following adequate purging of five (5) or more well
volumes. To determine the number of gallons within one (1) well volume, the following equation
was used: (Total depth of water) X (0.48 -conversion to well volumes in gallons) = # of gallons to
purge.
According to the US Environmental Protection Agency's (EPA's) Sampling Guidelines; "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)". While purging the three (3) wells, to
determine when sampling could commence, a Hanna HI 98703 Turbidity Meter and YSI 556 MPS
instrument were utilized to define turbidity, specific conductivity, temperature, and pH of
groundwater within.
2.2 Groundwater Analytical Methods
Samples were analyzed for volatile organic compounds (VOCs), 1,4-dioxane, semi -volatile
organic compounds (SVOCs), metals, and hexavalent chromium. Table 1 provides the analytical
methods that were used in the collection of these samples. Analytical methods including
laboratory quality control and quality assurance (QA/QC) procedures were performed by Prism
Laboratories, Inc. (NC Certification No. 402).

Sampling was done in general accordance with the January 2014 Inactive Hazardous Sites
Program's Guidelines for Assessment and Cleanup (DENR Guidance\NC DENR Guidance
Inactive Haz Sites.pdf) and the USEPA Technical Guidance (DENR Guidance\EPA Groundwater-
Sampling.pdf) documents except as noted below. Sampling was performed following adequate
WF.

purging and after chemical parameter stabilization criteria have been reasonably met.
According to the EPA sampling guidelines "Stabilization occurs when, for at least three
consecutive measurements, the pH remains constant within 0.1 Standard Unit (SU) and specific
conductance varies no more than approximately 5 percent."
SECTION 3
ANALYTICAL RESULTS
MW1, MW3A, and MW4A were initially sampled on May 26, 2015. The May 26 sampling event
occurred before the wells met the chemical parameter stabilization criteria (as defined above)
including low turbidity; therefore, the May sampling results are not an accurate indication of the
dissolved phase concentration levels of the constituents of concern. However, most constituents
were not identified during the May sampling event with the exception of the following metals:
mercury, arsenic, barium, chromium, and lead. Table 2 below provides a summary of
constituents of interest including those above the analytical reporting limits. A full laboratory
report including QC/QA data is provided in Appendix D of this report.

Falcon returned to the site to purge and sample the three (3) wells. The analytical methods were
also the same as provide in Table 1 above with the exception of not sampling for VOCs and
SVOCs. Not sampling for organic compounds was pre -approved by NCDENR due to not
detecting organic compound's during previous sampling events.
MW3A and MW4A were purged of 9 well volumes on July 20 and 21 2015. MW3A stabilized with
less than 10 NTUs. MW4A was also stable; however, the turbidity was at 24.7. NCDENR pre -
approved filtered and non -filtered samples from MW4A. MW 1 was purged of 17 well volumes on
July 21 and 22 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. MW1 was not sampled in August. Not sampling MW1 was also monitored by
NCDENR before and during sampling due to MW1 being installed already within the landfill
material and having previously documented contamination. Table 3 below provides a summary
of constituents of interest including those above the analytical reporting limits. A full laboratory
report including QC/QA data is provided in Appendix D of this report.

SECTION 4
SUMMARY OF FINDINGS
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. MW 1 was purged for two (2) additional days but failed to stabilize and was not sampled;
2. Barium, and Boron were detected at a concentration below the NC DENR 2L
Groundwater Standard at MW3A;
3. Barium was detected at a concentration below the NC DENR 2L Groundwater Standard
at MW4A in both the filtered and unfiltered samples;
4. Hexavalent Chromium was not detected in either down -gradient well.
SECTION 5
RECOMMENDATIONS
Falcon recommends that this report be submitted to NC DENR for their further review to assist
them in recommending next steps. Based on the sampling results, it appears the previously
identified coal combustion products have not exceeded the groundwater standards down
gradient of the landfill within the property boundaries. NC DENR will likely consider the Town of
Chapel Hill Police Department a low priority site. Following NC DENR review Falcon is available to
provide additional consultation and recommended courses of action to comply with possible
next steps.
