1.0 INTRODUCTION

ATC Associates of North Carolina, P.C. (ATC) was retained by Phillips 66 Company to conduct
site monitoring and remediation activities at the Former Conoco Store No. 33047 (RM No. 6182).
The project site is located at 1122 North Raleigh Street in Rocky Mount, Edgecombe County, North
Carolina. This report presents investigative procedures, field activities, and laboratory analytical
results performed during the reporting period.

2.0 SITE DESCRIPTION

2.1 Site Characterization
The site is located at the western corner of the intersection of North Raleigh Street and East
Grand Avenue in Rocky Mount, North Carolina. Figure 1 represents a site topographic map
and Figure 2 represents a site map indicating the site layout. The property consists of a single-
story concrete building and is currently a convenience store operating a retail gasoline
distribution system. Surrounding land usage is residential and commercial. Parker’s Canal is
located along the northern property boundary and discharges into Cowlick Branch. According to
the North Carolina Department of Environment and Natural Resources (NCDENR)-Division of
Water Quality, Cowlick Branch is identified as both Class C and Nutrient Sensitive Waters.
Currently, the site risk ranking is intermediate due to the presence of a surface water body within
500 feet of the site and the historical presence of free product.

2.2 Site Background
A free product release was discovered in the gasoline dispenser area on April 27, 1994. In
response, site assessment activities were conducted in July 1994. During assessment, petroleum
hydrocarbons were detected in soil and groundwater samples.

A Corrective Action Plan (CAP) was submitted to NCDENR in May 1996. During CAP
activities, free product was detected in select monitoring wells and petroleum concentrations in
groundwater exceeded 10 times the current groundwater standards. It was also confirmed there
was a leaking underground storage tank (UST) located at an Exxon gas station up-gradient of the
site which was currently undergoing remediation. A Phase I air sparge (AS) system was

installed and began operation in March 2001. To enhance remediation efforts, a Phase II AS/soil
vapor extraction (SVE) system was installed and began operation in September 2002. The Phase
I remediation system was discontinued in 2005.

ATC conducted groundwater sampling and aggressive fluid vapor recovery (AFVR) events
between February 2004 and November 2007, at which point Delta Environmental Consultants of
NC, P.C. (Delta) was contracted to continue environmental services at the site.

Due to the reduction of contaminant concentrations, the onsite remediation system was shut
down on February 11, 2009, as requested by ConocoPhillips and approved by NCDENR.

Delta conducted a groundwater sampling event in June 2010 and submitted a Semi-Annual
Groundwater Monitoring Report on September 16, 2010, recommending AFVR events and
groundwater sampling on a semi-annual basis.

Delta conducted two AFVR events which are reported in Free Product Recovery Reports dated
October 5, 2010, and March 17, 2011. On March 23, 2011, NCDENR issued a letter requesting
a sampling event and free product removal.

In April 2011, ATC was awarded the ConocoPhillips contract to continue groundwater
remediation activities at the site. ATC performed an AFVR event on July 21, 2011, and a
groundwater sampling event on August 4, 2011. The field activities were documented in a
Monitoring Report dated September 21, 2011.

On October 5, 2011, NCDENR issued a letter recommending continued AFVR events and
semiannual sampling. ATC submitted a Groundwater Monitoring Report on March 28, 2012,
documenting two AFVR events conducted in December 2011 and January 2012 and a
groundwater sampling event performed in February 2012.

On May 1, 2012, ConocoPhillips separated into two companies, ConocoPhillips and Phillips 66
Company. The environmental remediation activities associated with this site are managed by
Phillips 66 Company.

On December 21, 2012, a Groundwater Monitoring Report was submitted documenting three
AFVR events conducted in July 2012, August 2012, and September 2012 and a groundwater
sampling event performed in October 2012.

On September 17, 2013, a Groundwater Monitoring Report was submitted documenting three
AFVR events conducted in April 2013, May 2013, and June 2013 and a groundwater sampling
event performed in July 2013.

This Groundwater Monitoring Report documents three AFVR events conducted in November
2013, December 2013, and January 2014 and a groundwater sampling event performed in
February 2014.

3.0 GROUNDWATER CHARACTERIZATION

3.1 Groundwater Levels
On February 20, 2014, groundwater levels were measured in monitoring wells MW-1, MW-3, MW-
4, MW-5R through MW-11, MWHS-10, and MWHS-11. At the time of sampling monitoring well
MW-2 could not be located. An oil/water interface probe was used to measure the depths to water
and free-phase product. Free product was detected in well MWHS-10 at a thickness of 0.15 feet
and in MWHS-11 at a thickness of 0.02 feet. Depths were measured from the top of the well
casings, which are referenced to an arbitrary benchmark of 100.00 feet. The locations of the
monitoring wells are shown in Figure 2. Monitoring well construction details and current
groundwater elevation data are summarized in Table 1 and historical groundwater elevations for the
site are presented in Table 2. A groundwater elevation contour map based on February 2014 data is
included as Figure 3.

3.2 Groundwater Quality
On February 20, 2014, groundwater samples were collected from monitoring wells MW-1, MW-3,
MW-4, MW-5R through MW-11, MWHS-10, and MWHS-11. Monitoring wells MWHS-10 and
MWHS-11 could not be sampled due to the presence of free product. The samples were transported
under chain of custody to Lancaster Laboratories in Lancaster, Pennsylvania. The groundwater
samples were analyzed for volatile organic compounds by Standard Method 6200B. Copies of the
laboratory analytical results for groundwater samples are included in Appendix A. Groundwater
analytical results for the February 2014 sampling event are summarized in Table 3.

The laboratory analytical results from the February 20, 2014, sampling event indicate that the
following compounds meet or exceed the Title 15A NCAC 2L.0202 (2L) standards:
• Benzene: MW-4
• Methyl tertiary butyl ether (MTBE): MW-5R
• Naphthalene: MW-4
The 2B Standards for Class C/Nutrient Sensitive Waters (2B) were exceeded for:
• n-butylbenzene: MW-4
All other constituents analyzed by Standard Method 6200B were detected below 2L Standards, 2B
Standards, and Gross Contaminant Levels (GCLs).

Dissolved benzene, MTBE, and naphthalene isoconcentration contour maps are included as Figures
4 through 6, respectively. Historical groundwater analytical results are summarized in Table 4.

4.0 AGRESSIVE FLUID VAPOR RECOVERY EVENTS

ATC supervised A&D Environmental, Inc. (A&D) during AFVR events performed on
November 20, 2013, December 19, 2013, and January 23, 2014. Extraction was performed from
monitoring well MWHS-10. Prior to the events, ATC measured free product in well MWHS-10.
Free product thickness for the November 2013, December 2013, and January 2014 AFVR events
were measured at 0.66 feet, 0.31 feet, and 0.20 feet, respectively. At the conclusion of the
November 2013 event, 1,642 gallons of petroleum-impacted water were removed from the site.

At the conclusion of the December 2013 event, approximately 2,649 gallons of petroleum-
impacted water were removed from the site. Finally, at the conclusion of the January 2014
event, 1,884 gallons of petroleum-impacted water were removed from the site. Free product was
not detected in well MWHS-10 following any events. Figure 7 presents the historical free
product thickness in MWHS-10. The waste disposal manifests are included as Appendix B.

5.0 MONITORING PLAN AND SCHEDULE

The groundwater sampling schedule will continue on a semi-annual basis. The next sampling
event is scheduled for August 2014. The next monitoring report will be submitted by October
31, 2014.

6.0 SUMMARY

During this reporting period, ATC conducted a groundwater sampling event and performed three
AFVR events at the site. A summary of field activities and groundwater analytical data indicated
the following:

• Parker’s Canal is located along the northern property boundary and discharges into Cowlick
Branch, which is identified as both Class C and Nutrient Sensitive Waters;
• The northernmost edge of the contaminant plume is approximately 170 feet south of Parker’s
Canal;
• Groundwater flow is to the north, across the site;
• During the sampling event, free product was detected in MWHS-10 at a thickness of 0.15 feet
and in MWHS-11 at a thickness of 0.02 feet;
• Contaminant concentrations exceeding the 2L Standards were detected in monitoring wells
MW-4 and MW-5R. None of the compounds exceeded the GCLs;
• Contaminant concentrations exceeding the 2B Standards were detected in monitoring well
MW-4;

• An approximate total of 6,175 gallons of petroleum-impacted water were removed from the site
during three AFVR events performed in November 2013, December 2013, and January 2014.
Free product thickness was measured at 0.66 feet (November), 0.31 feet (December), and 0.20
feet (January) prior to the events; and
• Historic free product thickness levels in MWHS-10 show a decreasing trend since the AFVR
events have been performed.

ATC recommends continued semi-annual sampling at the site. ATC also recommends periodic
AFVR events to recover free product from the site and to decrease contaminant concentrations.

(1) The result for one or both determinations was less than five times the LOQ.
(2) The unspiked result was more than four times the spike added.

Matrix QC may not be reported if insufficient sample or site-specific QC samples were not submitted. In these
situations, to demonstrate precision and accuracy at a batch level, a LCS/LCSD was performed, unless otherwise
specified in the method.

All Inorganic Initial Calibration and Continuing Calibration Blanks met acceptable method criteria unless

Explanation of Symbols and Abbreviations

3768 0713
The following defines common symbols and abbreviations used in reporting technical data:
RL Reporting Limit BMQL Below Minimum Quantitation Level
N.D. none detected MPN Most Probable Number
TNTC Too Numerous To Count CP Units cobalt-chloroplatinate units
IU International Units NTU nephelometric turbidity units
umhos/cm micromhos/cm ng nanogram(s)
C degrees Celsius F degrees Fahrenheit
meq milliequivalents lb. pound(s)
g gram(s) kg kilogram(s)
µg microgram(s) mg milligram(s)
mL milliliter(s) L liter(s)
m3 cubic meter(s) µL microliter(s)
pg/L picogram/liter
< less than - The number following the sign is the limit of quantitation, the smallest amount of analyte which can be
reliably determined using this specific test.
> greater than
ppm parts per million - One ppm is equivalent to one milligram per kilogram (mg/kg), or one gram per million grams. For
aqueous liquids, ppm is usually taken to be equivalent to milligrams per liter (mg/l), because one liter of water has a
weight very close to a kilogram. For gases or vapors, one ppm is equivalent to one microliter per liter of gas.
ppb parts per billion
Dry weight Results printed under this heading have been adjusted for moisture content. This increases the analyte weight
basis concentration to approximate the value present in a similar sample without moisture. All other results are reported
on an as-received basis.
Data Qualifiers:
C – result confirmed by reanalysis.
J - estimated value – The result is ≥ the Method Detection Limit (MDL) and < the Limit of Quantitation (LOQ).
