GROUNDWATER MONITORING REPORT
BP SERVICE CENTER

PIKEVILLE, NORTH CAROLINA 27863

1.0 Introduction and Background

1.1 Introduction

Danny S. Pender is the property owner of a site which was formerly operated as the BP Service Center
facility located at 4673 US Highway 117 North in Pikeville, North Carolina. Figure 1 illustrates the
location of this facility on the Pikeville Quadrangle U.S.G.S. Topo Map. This facility contains one
permanent structure which is used as a gasoline convenience store but is currently vacant. The site
formerly contained (1) 3,000 gallon gasoline UST which was removed from this facility on December
27, 1993. A release was noted from this UST during closure activities. Assessment activities including
a LSA report, CSA activities conducted in 1994, and installation of additional monitoring wells have
been conducted at this site through 2010. Most recently, secondary sources (contaminated soil) were
removed from the site in the former pump island area in October, 2012. Figure 2 illustrates the layout of
this site, the UST locations, and the monitor well locations.

The NCDEQ recently issued an NORR requesting that the following tasks be conducted at this site prior
to proceeding with development of a Corrective Action Plan for this facility:

• Sample (10) existing wells and (2) area supply wells
• Install nutrient socks in wells formerly containing 2L violations
• Submit a groundwater monitoring report

This report contains findings reached following conducting these requested activities at 4673 US
Highway 117 North in Pikeville, NC.

1.2 Scope of Services

This Groundwater monitoring report contains documentation concerning the following activities which
have been conducted at this facility:

o A monitoring well sampling event conducted on November 2, 2017, consisting of sampling of 10
monitoring wells installed in conjunction with the on-site release and sampling of 2 nearby water
supply wells.

o Laboratory analyses of groundwater samples conducted by Pace Analytical, Inc. of Huntersville,
NC

o Estimation of the approximate groundwater flow direction and hydraulic gradient at the site.

o Isoconcentration maps illustrating the current contaminant levels in the monitoring wells at the
facility.

2.0 Field Activities

2.1 Ground Water Flow Direction and Gradient

In order to estimate the groundwater flow direction in the vicinity of the petroleum release, elevations of
the monitor well casings were measured using surveying equipment. Static water levels were obtained
from each of the wells and the data was used to compute a potentiometric surface map which is included
as Figure 3.

Groundwater data and monitoring well information, which are summarized in Table 1, were also used to
estimate the hydraulic gradient at the project site. Using the horizontal distance between the monitor
wells and the static water levels, the groundwater was estimated to be flowing in both a southwest
direction with a horizontal hydraulic gradient of approximately 0.0144 ft/ft and a northwest direction
with a gradient of 0.003 ft/ft. These apparent flow directions result from apparent remedial pit
excavation groundwater mounding as was noted on November 2, 2017.

2.2 Monitor Well Sampling and Analyses

On November 2, 2017, ten on-site and off-site monitor wells were sampled for analyses utilizing EPA
Methods 6200B plus MTBE, IPE, & EDB. Before sampling, the monitor wells were purged by
removing a minimum of three well volumes to ensure that the samples were representative of the actual
groundwater conditions. The monitor wells were developed using disposable plastic balers suspended
with unused nylon string. Following development of the groundwater monitoring wells, samples were
obtained from the disposable balers.

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 indicate the presence of 6 compounds above the current listed 2L Standards
in the monitor well network at this site. Total BTEX was detected at a maximum level of 1,060 ug/l in
well MW-7. Benzene was detected at a maximum concentration of 110 ug/l in MW-7, above its 2L
standard of 1 ug/l but below its GCL of 5,000 ug/l. No GCL violations were noted at the site.
Naphthalene was detected at a maximum concentration of 130 ug/l in monitoring well MW-7, and
MTBE was noted at a maximum level of 420 ug/l in well MW-18 above its 2L Standard of 20 ug/l.
Table 2 summarizes the laboratory analytical results, and Appendix A contains a copy of the laboratory
analytical report and chain of custody records. Figure 4 contains a benzene iso-concentration map,
Figure 5 illustrates the estimated Total BTEX concentration map, Figure 6 illustrates the naphthalene
isoconcentration for the site, and Figure 7 illustrates the MTBE isoconcentrations.

2.3 Supply Well Sampling and Analyses

On November 2, 2017, two off-site area supply wells were sampled for analyses utilizing EPA Methods
6200B plus MTBE, IPE, & EDB. Before sampling, the supply wells were purged by pumping from the
wells for approximately 10 minutes to ensure that the samples were representative of the actual
groundwater conditions. After pumping, the flowrate was reduced for collection of samples. Samples
were obtained from spigots closest to the various supply wells. The two supply wells sampled included:
IW-3 (Incorrectly labeled SW4), owned by Mattie Artis, used for irrigation purposes and SW-8, owned
by David Daw, used as a water source at JuDee’s Hair & Body. Supply well SW-1 formerly operated
by the NC State Historic Mechanics Shop is no longer in service since this tenant has vacated the
property. Additionally, supply well SW-4 is no longer in service since Morris Reed has connected his
residence to municipal water supply.

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 failed to indicate the presence of any compounds above laboratory
detection limits in either supply well sampled. Table 2 summarizes the laboratory analytical results, and
Appendix A contains a copy of the laboratory analytical report and chain of custody records. Table 5
summarizes supply well owner information

2.4 Plume Development

In prior sampling events conducted at the site, contaminants have been reported above 2L Standards in
on-site and off-site monitoring wells and in off-site water supply wells. The Travis Thigpen well (SW-
1) is no longer in operation since the tenant vacated the property.

The contaminant concentrations in well MW-18 downgradient of the source area had continually
decreased since the initial sampling event conducted on April 18, 2013, most likely due to soil
remediation; however, the latest 3 sampling events indicate an increase in the MW-18 BTEX level.
Total BTEX concentrations in groundwater in the pump island source area, previously above its GCL
for benzene, have remained below detection limits in MW-8A as a result of soil remediation.

The groundwater flow direction has remained towards both the southwest and southeast during the
November 2, 2017 sampling event. This flow direction is apparently due to significant groundwater
mounding the dispenser island remedial excavation area in which gravely backfill was used within a
predominantly clay-rich native soil site. Seasonal BTEX increases in the southeast direction towards
MW-7 and MW-2 were noted during the November 2, 2017 sampling event. In general, contaminant
concentrations appear to be reducing at site in all wells except for the recent spikes noted in
downgradient directions. Historical analytical laboratory data are summarized in detail on Table 3 and
Table 4. Installation of nutrient socks in monitoring wells MW-1, MW-2, MW-3, MW-7, MW-9, MW-
14, MW-12, MW-16, MW-17 & MW-18 should accelerate natural processes in these areas.

4.0 Conclusions and Recommendations

4.1 General Summary

A groundwater monitoring sampling event has been conducted at the BP Service Center facility located
at 4673 US Highway 117 North in Pikeville, NC. From a review of all information gathered during this
remediation project, Henry Nemargut Engineering Services makes the following conclusions:

o 6 petroleum compounds were detected in on and off site monitoring wells above 2L Standards
during the November, 2017 sampling event. Total BTEX was detected at a maximum level of
1,060 ug/l in well MW-7. Benzene was detected at a maximum concentration of 110 ug/l in
MW-7, above its 2L standard of 1 ug/l but below its GCL of 5,000 ug/l. No GCL violations
were noted at the site. Naphthalene was detected at a maximum concentration of 130 ug/l in
monitoring well MW-7, and MTBE was noted at a maximum level of 420 ug/l in well MW-18
above its 2L Standard of 20 ug/l.

o Two nearby in-use water supply wells were sampled, indicating no petroleum contamination.
The two supply wells sampled included: IW-3 (incorrectly labeled SW4), owned by Mattie Artis,
used for irrigation purposes, and SW-8, owned by David Daw, used as a water source at JuDee’s
Hair & Body.

o The groundwater flow direction remains towards both the southwest and southeast during the
November 2, 2017 sampling event. This shift in the flow direction is apparently due to
significant groundwater mounding the dispenser island remedial excavation area in which
gravely backfill was used within a predominantly clay-rich native soil site.

o Seasonal BTEX increases in the southeast direction towards MW-7 and MW-2 were noted
during the November 2, 2017 sampling event. In general, contaminant concentrations appear to
be reducing at site in all wells except for the recent spikes noted in downgradient directions.

o Nutrient socks were installed in monitoring wells MW-1, MW-2, MW-3, MW-7, MW-9, MW-
14, MW-12, MW-16, MW-17 & MW-18. Installation of these socks should accelerate natural
processes in these areas.

4.2 Recommendations

Based on information obtained during this sampling event, Henry Nemargut Engineering Services
makes the following recommendations for this site:

o Semi-annual monitoring should be continued at this site.

o Nutrient socks should be replaced on a semi-annual basis at this site.
