SECTInN i
INTRODUCTION
Falcon Engineering, Inc. (Falcon) conducted an Environmental Site Characterization in general
accordance with the January 2014 Inactive Hazardous Sites Program's Guidelines for Assessment
and Cleanup. This 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. Additional figures detailing sample locations are 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 35,000 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 Project Objective and Scope of Work
The Town of Chapel Hill retained Falcon to conduct this Environmental Site Characterization. The
purpose of the investigation was to further delineate environmental conditions present at the site
in regards to the former use as an ash landfill. Previous work conducted at the site is detailed
below (Phase I ESA & Limited Phase 11) but is provided under a separate cover:
The 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 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.
• Comparison of analytical results to applicable criteria.
Based on findings of those investigations NCDENR requested the lab results from two down
gradient monitoring wells and additional composite samples of the ash landfill area. 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 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 the site had significant amount
of fill materials placed at one time. There is a steep slope along the southern portion of the
property, where it was apparent that significant coal combustion products (CCPs) and debris
were placed on the site.

SECTION 2
METHODS OF INVESTIGATION
2.1 Monitoring Well Installation
In previous investigative efforts, two (2) groundwater monitoring wells had been installed, MW-1
a permanent well and MW-2 a temporary well. MW-1 was installed adjacent to the southwest of
the Police Station Building. MW-2 was installed between the subject property and Bolin Creek.
Results from these sampling activities were provided in previously submitted reports to NC DENR.
The first phase of this investigation involved the installation of two (2) down gradient
groundwater monitoring wells on January 27, 2014. MW-3 was placed down gradient of the
CCPs within the wooded area north of Bolin Creek Greenway Trail. MW-3 was located towards
the western side of the subject property. MW-4 was placed downgradient of the CCPs, also
within the wooded area north of Bolin Creek Greenway Trail. MW-4 was located toward the
eastern side of the subject property. The installation depth of MW-3 was 11.0 ft below ground
surface (bgs) and the installation depth of MW-4 was 9.2 ft bgs. Initial groundwater depths were
recorded at 3.4 ft bgs for MW-3 and 4.1 ft bgs for MW-4. It should be noted that the shallow
depths and auger refusal may have been due to the natural geology located in this area and
the sites close proximity to Bolin Creek. Well Construction records are provided in Appendix C of
this report.
The installation of an additional well was attempted (MW-5) as an up -gradient well to determine
background groundwater concentrations. This well was 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 ft 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.
Following installation of these wells, these wells were developed on January 29-30, 2014. Falcon
utilized Region 4 EPA guidance document for the Design and Installation of Monitoring Wells.
The method of purging the wells was by pumping and bailing. Per the established guidance, 24-
4

hours were allowed for the surface pad and protective casing to settle and at least 24-hours
were allowed in between purging and sampling. Both wells recharged following adequate
purging of at least three (3) well volumes or the wells being purged dry.
2.2 Groundwater Sampling
Following installation, development and purging of these down gradient groundwater
monitoring wells, environmental sampling was conducted. This sampling was performed on
February 5, 2014 and was completed in accordance with the January 2014 Inactive Hazardous
Sites Program's Guidelines for Assessment and Cleanup. Based upon this guidance, Table 1
provides the analytical methods that were used in the collection of these environmental
samples. All analytical methods were performed by Prism Laboratories, Inc. (NC Certification
No. 402). Falcon utilized these parameters for the sampling of MW-3 and MW-4. Table 2
provides a summary of those constituents that were above the analytical reporting limits. A full
laboratory report is provided in Appendix D of this report.

2.3 Surface Water Sampling
Bolin Creek runs adjacent to the subject property, bordering the southern property line. As the
natural topography drains in the southern direction towards Bolin Creek, Falcon collected two
grab samples from Bolin Creek to determine any potential impacts to this water body via
groundwater or surface water runoff. The Bolin Creek samples, consisted of one downstream
sample (BC-2) and one upstream sample (BC-1). This sampling method allowed for the
collection of a background sample, via BC-1, prior to this water body encountering this property,
and an impacted sample, via BC-2 after this water body would of seen surface runoff from this
property. This sampling was performed on February 5, 2014 and was completed in accordance
with the January 2014 Inactive Hazardous Sites Program's Guidelines for Assessment and
Cleanup. The same analytical methods outlined in Table 1 above were also used for the analysis
of these collected surface water samples. All analytical methods were performed by Prism
Laboratories, Inc. (NC Certification No. 402). Table 3 provides a summary of those constituents
that were above the analytical reporting limits. A full laboratory report is provided in Appendix D
of this report.

2.4 Composite Soil Sampling
To determine the nature and extent of potentially contaminated soils, Falcon performed
composite soil sampling at three locations along the southern property line. Sampling was
conducted according to the January 2014 Inactive Hazardous Sites Program's Guidelines for
Assessment and Cleanup and approved EPA sampling protocol for General Composite Sample
Collection Procedures. Composite soil sample locations consisted of locations identified as S-5,
S-6, and S-7. All three locations were in areas observed to be potentially exposed CCP. The
samples were taken by auger and consisted of 4.0 feet of material just below removed leaf litter.
The samples were then placed in large bags and thoroughly combined before sampling. This
sampling was completed on January 31, 2014. Figure 2 provided in Appendix A provides a
visually depiction of these sampling locations. The sampling figure denotes locations as well as
pictures in Appendix B. Table 4 below provides a summary of sampling results that were above
the established laboratory reporting limits.

2.5 Geoprobe Soil Sampling
To provide a preliminary delineation of potentially present CCPs, a geoprobe was mobilized to
advance into the soils on the subject property. Troxler Geologic was contracted to provide
these geoprobe services under the direction of Falcon staff. Falcon established a sampling grid
across the horizontal extent of the subject property to determine the presence or absence of
disposed CCPs. A visual depiction of these sampling locations can be found in Appendix A of
this report.
Table 5 below provides summary data for each of the geoprobed locations. 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.
Table 6 provides a summary of the analytical results for the collected geoprobe soil samples.
This summary table provides only those constituents that were reported above the established
laboratory reporting limits. Full detailed laboratory analysis can be found within Appendix D of
this report.

SECTION 3
SITE GEOLOGY AND HYDROGEOLOGY
3.1 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).
3.2 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 geoprobe soil profiles.
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. All stormwater
drains from this site into Bolin Creek. Very little, if any, surface water comes onto the site from
offsite.

SUMMARY OF FINDINGS
Falcon Engineering, Inc. completed an Environmental Site Characterization at 828 Martin Luther
King Jr. Boulevard located in Chapel Hill, North Carolina. The purpose of the investigation was to
evaluate the on -site soils and groundwater for potential CCPs within the property boundaries.
For this investigation, our scope of services consisted of the collection of composite soil samples,
groundwater samples and surface water samples to determine the existing conditions present
on the subject property. Sampling activities included the following:
• Collection of three (3) composite soil samples via hand augered locations in the area of
suspected CCP disposal. These sampling locations were identified as S-5, S-6, and S-7.
• Collection of two (2) groundwater samples identified as MW-3 and MW-4. A duplicate
sample was collected as a quality assurance sample from MW-3 and was identified as
MW-3A.
• Collection of two (2) surface water samples from Bolin Creek. BC-1 was collected as an
up gradient grab sample and BC-2 was collected as a down gradient sample.
In addition, Falcon advanced twelve (12) geoprobe borings into pre -defined locations
throughout property to transect and attempt to delineate the vertical and horizontal
extents of potential CCPs located at the subject property.
Based upon our completed field activities and subsequent laboratory analysis Falcon was able
to provide the following findings:
1. Composite soils sampled confirmed the presence of CCPs at the subject property.
Laboratory results confirmed the presence of Arsenic, Barium, Chromium, Lead, and
Selenium within the collected samples. Barium and Chromium were reported to be
above the NC DENR Soil to Groundwater MSCCs. Only Barium was reported to be above
the NC DENR Residential MSCCs on a few samples.
I JF

2. Groundwater collected from MW-4 appears to have been impacted from the leaching
of CCPs. Based upon laboratory data, levels of Mercury, Arsenic, Barium, Chromium,
Lead and Selenium were all above the NC DENR 2L Groundwater Standard.
3. Groundwater collected from MW-3 showed reported concentrations of Barium within the
sample, but was below the NC DENR 2L Groundwater Standard.
4. Surface water sampled from Bolin Creek did not exhibit results indicative of
environmental contamination above established NC DENR Surface Water Standards for
water supply sources or freshwater aquatic life.
I JF

SECTION 5
RECOMMENDATIONS
In response to this investigation, The Town of Chapel Hill has authorized Falcon to restrict public
access via the installation of fencing along the south portions of the property in which the CCPs
is visibly exposed. The Town of Chapel Hill has also authorized Falcon to install silt fencing along
this southern property line to mitigate the potential for these CCPs to migrate offsite as a result of
stormwater run-off. Additional silt fencing was also installed along the toe of the hill along this
southern property to prevent further erosion and migration of these materials from the hillside.
These measures are prudent cautionary measures to prevent CCPs from leaving the site and to
deter public access into these identified areas.
Falcon recommends that these results be submitted to NC DENR for further review and
consultation. Additional sampling of the installed groundwater monitoring wells can be
performed on a routine schedule as dictated by NC DENR or desired by the Town of Chapel Hill.
It is recommended that this area be inspected on a quarterly basis to ensure the preventative
measures are remaining in proper functional order. While these preventative measures provide
an adequate short-term mitigation, a more permanent solution should be considered following
consultations with NC DENR. Falcon is available to provide additional consultation and
recommended courses of action for these solutions.
