2.0 SITE ASSESSMENT

2.1 Site Description

The subject property (site) is located at 6154 West Mount Drive in a mixed-use area
within the jurisdictional limits of Rocky Mount, North Carolina (Figure 1). The site is improved
with two one-story buildings. Claude’s Construction, Inc. currently occupies one of the dwellings
and the second building is vacant. The site formerly maintained two 6,000-gallon underground
storage tanks (USTs), both of which were removed from the ground in March 1994. The contents
of the USTs currently are unknown. The site further is improved with asphalt, gravel, and
concrete parking/access areas and a canopy cover. A chain link fence surrounds the rear of the
property where a propane aboveground storage tank (AST) is located. The property is bordered
to the west by South Old Carriage Road and to the southeast by West Mount Drive. Residential,
commercial, and agricultural parcels are located in all directions from the site. The site obtains
potable water from an on-site water supply well WSW-1. Water supply well WSW-1 also
supplies potable water to a residence located at 6164 West Mount Drive. A site plan depicting
pertinent features of the subject property is provided as Figure 2. A summary of the physical
properties of gasoline and diesel, typical petroleum fuels of similar properties, are presented as
Appendix A.

2.2 Site History

February 1994:
Tank closure activities associated with the referenced USTs were conducted in 1994.
During excavation activities, a petroleum sheen was observed on groundwater encountered in the
UST basin. Laboratory analyses performed on the soil samples collected from the UST basin,
product lines and dispenser yielded total petroleum hydrocarbon concentrations in excess of the
North Carolina State Action Level of 10.0 parts per million.

2005 to 2008:
Due to the presence of residual-phase impacts observed during UST closure activities,
NCDENR requested further investigation to evaluate the extent of the confirmed impacts and the
potential risk to human health and the environment. Six two-inch monitoring wells (MW-1, MW-
1D, MW-2, MW-3, MW-4, and MW-5 were installed at the site. According to the historical
information obtained by CES, monitoring well MW-3 was installed proximal to the former UST
basin. Monitoring wells MW-1 and MW-1D were installed west of the existing canopy.
Monitoring wells MW-2, MW-4, and MW-5 were installed at various locations across the site to
determine vertical and horizontal plume extents and to establish the hydraulic gradient.
Subsequent chemical analyses revealed dissolved-phase petroleum compound concentrations in
excess of the North Carolina 15A NCAC 2L .0202 (2L) groundwater standards in samples
collected from monitoring wells MW-1, MW-1D, MW-3, MW4, and MW-5.

The on-site supply well (WSW-1) and two adjacent supply wells (WSW-2 and WSW-3)
also were sampled. Chloromethane was measured in excess of the 2L standard in samples
collected from supply wells WSW-2 and WSW-3. No additional analytes were measured at, or in
excess of, the respective laboratory method detection limits in samples collected from supply well
WSW-1.

July 2009 to February 2010:
In accordance with regulatory directives, Terraine, Inc. (Terraine) performed multiple
monitoring events in 2009 and 2010. Laboratory analytical results indicated elevated
concentrations of dissolved-phase petroleum compounds in excess of the 2L groundwater
standards in samples collected from monitoring wells MW-1, MW-3, and MW-4. A
WellBoom™ manufactured by Universal Remediation, Inc. was installed in monitoring well
MW-1 subsequent to sample collection. Samples collected from water supply wells WSW-2 and
WSW-3 did not reveal measurable concentrations above the respective laboratory method
detection limits. Water supply well WSW-1 was not sampled during this timeframe.

September 2010 to May 2011:
In accordance with further regulatory directives, Terraine supervised the installation of
two additional two-inch monitoring wells MW-6 and MW-7 in September 2010 to in an effort to
define the northeast and southern edge of the dissolved-phase contaminant plume. Subsequent
groundwater analyses revealed dissolved-phase petroleum impacts in excess of the 2L
groundwater standards in samples collected from monitoring wells MW-1, MW-3, MW-4, MW-
6, and MW-7. Lead was measured above the laboratory method detection limit in the samples
collected from monitoring wells MW-1D and MW-2. Lead was detected above the 2L standard
in the sample collected from supply well WSW-3. No additional analytes of concern were
measured at, or in excess of, the respective laboratory method detection limits in the samples
collected from supply wells WSW-1 and WSW-2.

5

Terraine completed an additional monitoring event in May 2011. Analytical results
revealed elevated dissoled-phase concentrations in excess of the 2L groundwater standards in
samples collected from monitoring wells MW-1, MW-1D, MW-2, MW-3, MW-4, MW-6, and
MW-7. Petroleum impacts were not identified in samples collected from supply wells WSW-1
and WSW-2. Water supply well WSW-3 was unable to be sampled during this monitoring event.

2.3 Topography

The subject site is located within the jurisdictional limits of Rocky Mount, North
Carolina and is situated in the Yorktown Formation and Duplin Formation, Undivided and
located in the Pre-Mesozoic Basement of the Coastal Plain Physiographic Province. According to
the U.S. Geological Survey 7 ½ Minute Series Topographic Map of the Rocky Mount
Quadrangle, North Carolina, the site elevation is approximately 176.0 feet above mean sea level.
The nearest identified surface water body, an unnamed pond, is located approximately 750 feet
east of the subject site. There are additional small ponds located in all directions from the site
within 1,000 feet.

2.4 Local Geology

CES reviewed the Geologic Map of North Carolina prepared by the Department of
Natural Resources and Community Development, dated 1985. Published geologic information
indicates that local geologic structures primarily comprise the Yorktown Formation and Duplin
Formation, Undivided and located in the Pre-Mesozoic Basement of the Coastal Plain
Physiographic Province.

Yorktown Formation – Fossiliferous clay with varying amounts of fine-grained sand,
bluish gray, shell material commonly concentrated in lenses; mainly in the area north of the
Neuse River.

Duplin Formation – Shelly, medium- to coarse-grained sand, sandy marl, and limestone,
bluish-gray; mainly in the area south of the Neuse River.

The above descriptions were extracted from the Geologic Map of North Carolina
prepared by the Department of Natural Resources and Community Development, dated 1985.

Drill cuttings collected during previous soil boring activities consisted of silty clay matrix
extending to approximately 14-feet below ground surface (bgs). Competent bedrock was not
observed during previous soil boring activities.

2.5 Receptor Survey

On December 13, 2011, CES performed an updated site reconnaissance to confirm the
presence of previously identified receptors located within a 1,000-foot search radius of the
subject property. CES identified three parcels located within the 1,000-foot radius. Visual
inspections were performed at the properties for evidence indicating the presence of supply
wells/springs. The approximate locations of the potential receptors are presented on Figure 3.
Table 1 is a summary of the potential receptors including property owner/occupant, address,
potable water usage, and the estimated distance/direction from the source area corresponding to
the locations presented on Figure 3.

2.6 Hydrogeology

In accordance with NCDENR directives, CES mobilized to the site on December 13,
2011 to perform a groundwater monitoring event to assess current dissolved-phase contaminant
levels and to confirm the presence or absence of free-phase petroleum. CES was unable to locate
the majority of the monitoring wells due to the large amount of gravel now covering the site. On
January 16, 2012, CES returned to the site with a metal detector and was able to locate all site
monitoring wells. Groundwater samples were collected from monitoring wells MW-1, MW-1D,
MW-2, MW-3, MW-4, MW-5, MW-6, and MW-7. CES also collected groundwater samples
from supply well WSW-3. Prior to purging and sampling, a Heron InstrumentsTM H.01L interface
probe was used to record the static water level and to investigate for the presence of free-product
at the monitoring points. CES recorded the static water levels using the interface probe from a
reference mark scribed at the top of the well casing. Groundwater flow at the site was determined
using the triangulation method of the relative groundwater elevations observed within the
monitoring points. Figure 4 is a potentiometric surface map generated from the relative
elevations of equilibrated groundwater as measured on January 16, 2012. Groundwater elevation
data is presented in Table 2.

Prior to sampling, CES purged the wells to remove suspended solid material from the water
column and to collect a sample representative of aquifer conditions. The wells were purged until a
minimum of three well volumes had been displaced. Exterior spigots were purged for approximately 10
minutes prior to collection of supply well samples. Groundwater samples were collected using dedicated,
disposable, high-density polyethylene (HDPE) bailers and were transferred directly into the appropriate
sample containers immediately upon collection. Disposable, nitrile gloves were used during all phases of
sample collection. The groundwater samples were labeled and maintained on ice pending delivery to an
independent laboratory. The supply well and monitoring well samples were submitted to Pace Analytical
Services, Inc. laboratory in Huntersville, North Carolina for volatile organic compounds (VOCs), MTBE,
and diisopropyl ether (IPE) via Standard Method (SM) 6200B. Strict sample security and chain-of-
custody documentation were maintained during all phases of transport. A summary of the calculated
purge volumes is presented in Table 3. A summary of current and historic groundwater quality data is
presented in Appendix C. Chain-of-custody documentation and the laboratory Certificates of Analyses
are included as Appendix D. A dissolved-phase concentrations of concern (COC) map displaying the
chemical analyses results for each monitoring well is included as Figure 5.

3.0 RISK ASSESSMENT

CES performed a risk assessment to evaluate the potential risk to human health and the
environment associated with the petroleum compounds detected at the site. The findings of the risk
assessment are presented in the following sections.

3.1 Identification of Receptors

The following sections present the potential on- and off-site receptors of petroleum
contaminants existing on-site and the possible pathways of exposure.

3.1.1 On-Site Receptors

The subject property is served potable water by on-site supply well WSW-1.
CES did not identify underground utilities on-site; therefore, impacts to any utilities is not
likely a concern.

3.1.2 Off-Site Receptors

The receptor survey performed during GMR activities identified three potential
receptors located within the 1,000-foot search radius. Groundwater analysis performed
on the sample collected from supply well WSW-3 did not yield measurable compound
concentrations above the respective laboratory method detection limits.

Based on topographic information, the nearest identified surface water body, an
unnamed pond, is located approximately 750 feet east of the subject site. There are
additional small ponds located in all directions from the site within 1,000 feet.

3.1.3 Identification of Exposure Pathways

The identification of potential exposure pathways is necessary to evaluate the
risk posed by the extent of the release. An exposure pathway requires that there be some
mechanism for any person or population to come into contact with one or more of the
media which contain the contaminant of concern. No risk is assumed in the absence of
contamination or in the absence of an exposure pathway.

3.1.3.1 Inhalation

The presence of asphalt, gravel, and concrete surfaces covering in the
immediate vicinity of the UST basins and product lines mitigates concern
associated with potential exposure to VOC vapors emanating from the
subsurface. Structures appearing to maintain basements were not observed
within the surrounding area. Therefore, concern associated with petroleum
vapors impacting surrounding subgrade structures likely is mitigated.

3.1.3.2 Ingestion

The presence of off-site private supply wells could serve as potential
exposure pathways to petroleum-impacted groundwater.

15
3.1.3.3 Dermal Contact

The UST basins and product lines are covered with asphalt, gravel, and
concrete mitigating concern associated with inadvertent contact with adsorbed-
phase contaminants.

4.0 GROUNDWATER MONITORING REPORT SUMMARY

Laboratory analyses performed on the groundwater samples collected during this investigation
yielded petroleum impacts in excess of the respective 2L groundwater standards in monitoring well MW-
1. MTBE was measured above the laboratory method detection limit in the sample collected from
monitoring well MW-5. The additional monitoring well and supply well samples collected did not yield
measurable levels of petroleum constituents above the respective laboratory method detection limits. The
observed trend of decreasing concentrations or asymptotic conditions likely indicates the occurrence of
natural attenuation. CES recommends additional groundwater monitoring to confirm the continued
decreasing contaminant trend. This report, prepared in accordance with NCDENR correspondence dated
November 23, 2011, is being delivered to Mr. Mark Petermann of the Raleigh, North Carolina NCDENR
office on January 23, 2012.
