RISK ASSESSMENT REPORT
UNC-CHARLOTTE MOORE HALL
SANFORD HALL LANE
CHARLOTTE, NORTH CAROLINA
Terracon Project No. 71177348
November 5, 2019
1.0 SITE DESCRIPTION
The former Moore Residence Hall site is comprised of approximately 1.56 acres of the 671.72-
acre main campus of UNC-Charlotte (UNCC) located in northeast Charlotte, Mecklenburg County,
North Carolina. The on -site building was formerly utilized as student housing on the UNC-
Charlotte campus but was recently demolished. The former location of the Moore Hall building is
depicted on Figures 1 and 2.
As requested by UNCC on August 27, 2019, Terracon mobilized to the site to identify and confirm
the presence of petroleum impacted soils discovered during demolition activities at the former
Moore Residence Hall building. While at the site, Terracon utilized a hand-held photo -ionization
detector (PID) to screen potentially impacted soils discovered near the southeastern corner of the
former building during grading operations. PID screening values of volatile vapors originating from
selected soils ranged from 134 parts per million (ppm) in the southern sidewall to 219 ppm in the
eastern sidewall of the excavation.
It is Terracon's understanding that UNC-Charlotte contracted with Summit Engineering (Summit)
to provide the soil profile sampling and manage the removal and disposal of the petroleum
impacted soils. The soil profile analysis of the soils planned for removal indicated total petroleum
hydrocarbons (TPH) diesel range organics (DRO) were detected at 580 milligrams per kilogram
(mg/kg) which is well above the North Carolina Department of Environmental Quality (NCDEQ)
regulatory action level. According to UNC-Charlotte documentation, approximately 174.23 tons
of impacted soils were transported to the Republic Landfill in Concord, North Carolina for disposal
in September 2019. Following removal of the impacted soils by Summit, Terracon was contracted
by UNCC to provide regulatory guidance and proceed to closure of the release incident. UNCC
and Terracon were not able to identify the source of the release of petroleum constituents. Soil
disposal manifests are included in Appendix C.
1.1 Standard of Care
Terracon's services were performed in a manner consistent with generally accepted practices of
the profession undertaken in similar studies in the same geographical area during the same time.
Terracon makes no warranties, either expressed or implied, regarding the findings, conclusions,
or recommendations. Please note that Terracon does not warrant the work of laboratories,
regulatory agencies, or other third parties supplying information used in the preparation of the

November 5, 2019 Terracon Project No. 71177348
report. The services were performed in accordance with the scope of work authorized by our
client, as reflected in our proposal and were not conducted in accordance with ASTM E1903-11.
1.2 Additional Scope Limitations
Findings, conclusions, and recommendations resulting from these services are based upon
information derived from the on -site activities and other services performed under this scope of
work; such information is subject to change over time. Certain indicators of the presence of
hazardous substances, petroleum products, or other constituents may have been latent,
inaccessible, unobservable, non -detectable, or not present during these services; thus, we cannot
represent the site is free of hazardous substances, toxic materials, petroleum products, or other
latent conditions beyond those identified during this investigation. Subsurface conditions may vary
from those encountered at specific borings or wells or during other surveys, tests, assessments,
investigations, or exploratory services. The data, interpretations, findings, and our
recommendations are based solely upon data obtained at the time and within the scope of these
services.
1.3 Reliance
This report has been prepared for the exclusive use of the UNCC. Any authorization for use or
reliance by another party (except a governmental entity having jurisdiction over the site) is
prohibited without the expressed written authorization of the UNCC and Terracon. Any
unauthorized distribution or reuse is at UNCC's sole risk. Reliance by authorized parties will be
subject to the terms, conditions, and limitations stated in the Supplemental Contract between
UNC-Charlotte and Terracon dated September 26, 2019 for risk -based sampling and reporting
associated with Residence Hall Phase XVI and the report.
2.0 FIELD ACTIVITIES
Terracon conducted the field work in accordance with a health and safety plan developed
specifically for this project. Work was performed using United States Environmental Protection
Agency (USEPA) Level D work attire consisting of a hard hat, safety vest, safety glasses,
protective gloves and protective boots.
2.1 Soil Sampling Activities
On October 1, 2019 after the impacted soils had been removed, Terracon personnel manually
advanced two hand auger borings (SSW and ESW) approximately 0.5 feet into the southern and
eastern sidewalls of the excavation. The side wall samples were collected about 3.5 feet above
the bottom of the excavation. The BOTTOM sample was collected with the hand auger at a depth
of approximately of 1 foot below the floor of the excavation. At the time of sampling, groundwater
seepage was encountered during advancement of the BOTTOM boring. Terracon notified Ms.

Risk Site Assessment Letter Report Irerracon
Former Moore Residence Hall Charlotte, NC
November 5, 2019 Terracon Project No. 71177348
Trudy Beverly at NCDEQ regarding the presence of groundwater in the excavation. Ms. Beverly
indicated a groundwater sample would not be required due to the site conditions being unsafe for
track mounted drill rig to access and install a temporary groundwater monitoring well in the
impacted soil area. Soils collected from each boring were screened in the field using a PID. PID
screening values ranged from 0.0 ppm in samples SSW and BOTTOM to 121.5 ppm in sample
ESW. A confirmation soil sample was collected from each of the three borings. A Boring Locations
and Analyses map showing the approximate locations of the soil borings is included as Figure 3.
Field notes are provided in Appendix A while photographs of the field activities are provided in
Appendix D.
The soil samples were placed in laboratory supplied glassware, labeled and placed within an ice -
packed cooler pending transport to Pace Analytical Services in Huntersville, North Carolina for
laboratory analysis of TPH gasoline -range organics (TPH-GRO) by EPA Method 8015/5030 and
TPH-DRO by EPA Method 8015/3545/3550, volatile organic compounds (VOCs) by EPA Method
8260B, and semi -volatile organic compounds (SVOCs) by EPA Method 8270D. Chain -of -custody
documentation accompanied the samples to the laboratory,
3.0 ANALYTICAL RESULTS
The analytical results for soil samples collected on August 27, 2019 (Summit Engineering) and
October 1, 2019 (Terracon Consultants) are discussed below.
Soil Profile Sampling by Summit Engineering (August 27, 2019)
TPH-DRO was detected in soil sample S-1 at 580 mg/kg above the regulatory action level
of 100 mg/kg.
TPH-GRO was detected in soil sample S-1 at 99 mg/kg above the regulatory action level
of 50 mg/kg.
Naphthalene was detected at 0.20 J mg/kg which is slightly above the Soil to Water
Maximum Soil Contaminant Concentration (MSCC). The remaining petroleum
constituents were detected in soil sample S-1 at concentrations below their respective
MSCCs.
Risk Assessment Sampling (October 1, 2019)
Petroleum constituent concentrations detected in soil sample ESW (eastern sidewall) are
below their respective MSCCs.
No petroleum constituents were detected in soil samples BOTTOM or SSW (southern
sidewall) above the laboratory method detection limits.
Acetone was detected in samples ESW and SSW below its MSCC. Acetone is considered
to be a laboratory artifact, not representative of the release at the site.

Soil analytical results are summarized in Table 1 and are depicted on Figure 3. The laboratory
analytical reports for Summit (Prism Laboratories) and Terracon (Pace Analytical) and chain -of -
custody records are provided in Appendix B.
4.0 CONCLUSIONS AND RECOMMENDATIONS
Based on the scope of services described in this report and subject to the limitations described
herein, Terracon provides the following conclusions.
No petroleum constituents were detected above their respective MSCCs in the soil
samples.
The impacted soils discovered at the site appear to have been effectively removed during
excavation activities.
O Groundwater seepage was encountered in the excavation; however, due to site
conditions, Terracon was unable to obtain a groundwater sample.
O Contiguous properties are developed as student housing for UNC-Charlotte.
O Well receptor information did not identify water -supply wells within a 1,500-ft radius of the
source area. Surrounding properties are connected to municipal water supplies. The
nearest surface water body is an unnamed tributary of Toby Creek located approximately
220 feet the north of the release area. None of the detected constituents exceeded the
2B surface water standards.
O The site currently meets the NCDEQ criteria for Low Risk status.
Based on the findings of our assessment activities, the following comments and recommendations
are provided for the site.
Terracon petitions the NCDEQ for regulatory closure of the release incident with a
No Further Action letter in accordance with the Guidelines.
