1.0 - SITE HISTORY, SOURCE CHARACTERIZATION & INITIAL ABATEMENT
Kroger Limited Partnership, I owned a multi-compartment UST which was formerly
operated at the Kroger Fuel Center R-349 facility located at 1673 Parkwood Blvd W in
Wilson, North Carolina. Figure 1 illustrates the location of this facility on the Wilson
Quadrangle U.S.G.S. Topo Map. This facility contains one permanent structure which is
used as a municipal hospital. The site formerly contained a multi-compartment UST wih
(1) 16,000 gallon gasoline UST and (1) 8,000 gallon gasoline UST. Figure 2 illustrates
the layout of this site & the UST location.
During UST closure operations conducted on April 16-19, 2013, a release was confirmed
upon receipt of analytical results from a water sample collected from a temporary
monitoring well installed in the former UST location. Groundwater was observed during
UST excavation in the tank pit. The site and adjacent properties are used for
commercial/hospital purposes. Municipal water supply from the City of Wilson serves
the site and is available to all properties within 1,500’.
A Limited Site Assessment (LSA) has been conducted in response to this release in order
to classify the risk of the site. The findings of the LSA conducted for this site are

3.0 - RECEPTOR INFORMATION
3.1 Water Supply Wells
A supply well survey has been conducted within a 1,500' radius of the release area. This
survey was conducted by interviews conducted with owners and occupants of properties
Page - 5
located within 1,500’ of the release sources. During this reconnaissance no water supply
wells (irrigation or potable) were found to be located within this radius. Figure 5 depicts
the approximate 1,500’ search radius for this site.
3.2 Public Water Supplies
Public water supplies are available to all properties within 1,500’ of the release site.
3.3 Surface Water
The partial Wilson Quadrangle U.S.G.S. Topographic Map included as Figure 1 indicates
that the release site is located on a slight slope at an approximate elevation of 135’ amsl.
Surface waters in the vicinity of the release area generally drain towards the east to
Hominy Swamp, which empties into the Contentnea Creek south of the release site.
3.4 Wellhead Protection Areas
No wellhead protection areas are known to exist within the area of this release.
3.5 Deep Aquifers in the Coastal Plain Physiographic Region
This release is located in the coastal plain. It is unknown if the shallow groundwater in
the release area feeds deep aquifers.
3.6 Subsurface Structures
Subsurface lines/structures are not present within the petroleum affected area at this site.
All subsurface utilities were removed when the UST facility was closed. Figure 3
illustrates the locations of subsurface utilities on the subject property in the vicinity of the
former UST.
3.7 Land Use
The UST facility has been closed and the commercial property is now vacant.
3.8 Property Owners and Occupants

4.0 - SITE GEOLOGY AND SOIL INVESTIGATION
4.1 Site Geology
The site is situated in the Coastal Plain. According to the Geological Map of North
Carolina local geology of the region is classified as the Yorktown Formation, underlain
by fossiliferous clay with varying amounts of fine-grained sand. Bedrock was not
encountered to a depth of 15 feet below surface which was the maximum depth explored
during the subsurface investigation.
4.2 Soils Investigation
The soils at the project site consist of clay with varying sand & silt content. Geologic
logs are contained in the previously submitted UST Closure report.
On April 16-18, 2013, following the excavation of the UST, piping and dispensers, soil
samples were collected from in-situ soils around the UST in accordance with NCDENR
guidelines. Tank pit samples were obtained from the walls around the perimeter of the
UST excavation at a depth of approximately 7’ below grade, above the observed water
table. Piping and dispenser samples were obtained from a backhoe bucket at a depth of
approximately 3’ below grade. Figure 3 depicts the locations of the release confirmation
samples obtained at this site. Release confirmation samples were analyzed for TPH-GRO
compounds per NCDENR guidelines. Sample collection and handling was conducted per
NCDENR and EPA protocol.
Laboratory TPH analytical results for release confirmation samples failed to indicate
GRO compounds above laboratory detection limits. Soil analytical report and the chain
of custody records for the soil samples collected at 1673 Parkwood Blvd W are contained
in the previously submitted UST Closure report.
5.0 – GROUNDWATER INVESTIGATION
5.1 Monitoring Well Installation
A total of one North Carolina Type II temporary groundwater monitoring well was
installed on-site during UST closure activities. Figure 7 illustrates the location of the
monitoring well, denoted as TW-1, which was placed immediately adjacent to the west
wall of the UST pit. The monitoring well was constructed of 2-inch Schedule 40 PVC
pipe with 5’ of casing and 10 feet of 0.010 inch slotted screen. Based on the assumption
that the contaminants being addressed were primarily hydrocarbon constituents with
specific gravities of less than 1.0, the Type II monitoring well was installed so that the
screened interval intersected the shallow groundwater table at the time of installation.
Well construction records are contained in the previously submitted IAA report.
Page - 7
5.2 Monitor Well Sampling and Analyses
On April 17, 2014, monitor well TW-1 was sampled for analyses utilizing EPA Methods
6200B, Pb, and MADEP Methods for VPH as appropriate based on UST contents.
Before sampling, the monitor well was developed by removal of 3 well volumes to
ensure that the samples were representative of the actual groundwater conditions. The
monitor well was then sampled using a disposable plastic baler suspended with unused
nylon string. Groundwater was detected in monitor well TW-1 at a depth of
approximately 8.54’ below top of casing prior to purging and sampling.
All samples were placed in laboratory supplied glassware, labeled with sample location,
analysis to be performed, time, date and sampler's name. The sample jars were then
immediately placed in a cooler, chilled with ice to approximately 4oC in preparation of
transportation to an analytical laboratory utilizing EPA approved chain-of-custody
procedures.
Laboratory analytical results from TW-1 indicated the presence of 2 gasoline related
compounds/compound groups above 15 NCAC 2L Standards. MTBE was noted at a
concentration of 717 ug/l in TW-1, above its 2L Standard of 20 ug/l. C5-C8 Volatile
Aliphatics were noted at a concentration of 573 ug/l in TW-1, above the 2L Standard of
400 ug/l for this compound group. No compounds were detected at levels above GCLs.
Table 4 summarizes the laboratory analytical results for the groundwater samples
collected from permanent and temporary monitoring wells. Laboratory analytical report
and chain of custody records for the groundwater samples are contained in the previously
submitted UST Closure report.
6.0 - CONCLUSIONS AND RECOMMENDATIONS
6.1 General Summary
Limited Site Assessment activities at 1673 Parkwood Blvd W have been completed.
From a review of all information gathered during this project, Henry Nemargut
Engineering Services makes the following conclusions:
Page - 8
o A well reconnaissance of the site was performed which identified no irrigation
wells within a 250’ radius of the release source area & no potable wells were
identified within 1000’ of the release source. Municipal water supplies are
available to all properties within 1500’ of this site.
o Confirmatory soil samples were obtained from the UST pit, beneath the product
piping and dispensers during UST closure activities. Results from all TPH-GRO
release confirmation samples were below laboratory detection limits. No risk-
based soil samples were analyzed since all TPH sample results were below
laboratory detection limits.
o One groundwater monitoring well was installed adjacent to the UST excavation
during UST closure activities. Free product was not observed in this monitoring
well prior to sampling on April 17, 2013.
o Laboratory analytical results from TW-1 indicated the presence of 2 gasoline
related compounds/compound groups above 15 NCAC 2L Standards. MTBE was
noted at a concentration of 717 ug/l in TW-1, above its 2L Standard of 20 ug/l.
C5-C8 Volatile Aliphatics were noted at a concentration of 573 ug/l in TW-1,
above the 2L Standard of 400 ug/l for this compound group. No compounds were
detected at levels above GCLs.
6.2 Recommendations
Based upon a review of all information gathered during this project, Henry Nemargut
Engineering Services makes the following recommendations:
o An NRP restricting use of groundwater at this site should be filed at the Wilson
County Register of Deeds office since groundwater contaminants exceed 15
NCAC 2L Standards.
o This site should receive a notice of “No Further Action” following filing of the
NRP and completion of public notice.
o A copy of this report will be forwarded to the following address:
