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 #33047 (RM #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 Environmental Quality (NCDEQ) 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 NCDEQ 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 NCDEQ.

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, NCDEQ 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, NCDEQ 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.

On May 12, 2014, a Groundwater Monitoring Report was submitted documenting three AFVR
events conducted in November 2013, December 2013, and January 2014 and a groundwater
sampling event performed in February 2014.

On July 31, 2015, a Groundwater Monitoring Report was submitted documenting a groundwater
sampling event performed in March 2015.

This Groundwater Monitoring Report documents a groundwater sampling event performed in
May 2016.

3.0 GROUNDWATER CHARACTERIZATION

3.1 Groundwater Levels
On May 16, 2016, 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 0.14 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 May 2016 data is included as Figure 3.

3.2 Groundwater Quality
On May 16, 2016, groundwater samples were collected from monitoring wells MW-1, MW-3,
MW-4, MW-5R through MW-11, and MWHS-11. Monitoring well MWHS-10 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 May
2016 sampling event are summarized in Table 3.

The laboratory analytical results from the May 16, 2016, sampling event indicate that the following
compounds meet or exceed the Title 15A NCAC 2L.0202 (2L) standards:
· Benzene: MW-4
· Naphthalene: MW-4
The 2B Standards for Class C/Nutrient Sensitive Waters (2B) were exceeded for:
· Benzene: MW-4
· Toluene: MW-4
· n-Butylbenzene: MW-4
All other constituents analyzed by Standard Method 6200B were either not detected or were
detected at levels below 2L Standards, 2B Standards, and Gross Contaminant Levels (GCLs).

A dissolved benzene isoconcentration contour map, a dissolved methyl tertiary butyl ether (MTBE)
concentration map, and a dissolved naphthalene isoconcentration contour map are included as
Figures 4 through 6, respectively. Historical groundwater analytical results are summarized in
Table 4. Figure 7 presents the historical free product thickness in MWHS-10.

4.0 MONITORING PLAN AND SCHEDULE

The groundwater sampling schedule will continue on a semi-annual basis. The next sampling
event is scheduled for November 2016. The next monitoring report will be submitted by January
31, 2017.

5.0 SUMMARY

During this reporting period, ATC conducted a groundwater sampling event 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 0.14 feet;
· Contaminant concentrations exceeding the 2L Standards were detected in monitoring wells
MW-4. None of the compounds exceeded the GCLs;
· Contaminant concentrations exceeding the 2B Standards were detected in monitoring well
MW-4; and
· Historic free product thickness levels in MWHS-10 have remained stable since the last AFVR
events were performed in late 2013 and early 2014.

Based on the most recent sampling event as well as historical sampling events, recalcitrant free
product is present in monitoring well MWHS-10. The product remains in this well despite
numerous high vacuum extraction events.

Explanation of Symbols and Abbreviations

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)

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. Laboratory Data Qualifiers:
B - Analyte detected in the blank C - Result confirmed by reanalysis E - Concentration exceeds the calibration range
J (or G, I, X) - estimated value ≥ the Method Detection Limit (MDL or DL) and < the Limit of Quantitation (LOQ or RL)
P - Concentration difference between the primary and confirmation column >40%. The lower result is reported. U - Analyte was not detected at the value indicated V - Concentration difference between the primary and confirmation column >100%. The reporting limit is raised due to this disparity and evident interference… Additional Organic and Inorganic CLP qualifiers may be used with Form 1 reports as defined by the CLP methods. Qualifiers specific to Dioxin/Furans and PCB Congeners are detailed on the individual Analysis Report.
Analytical test results meet all requirements of the associated regulatory program (i.e., NELAC (TNI), DoD, and ISO 17025) unless
otherwise noted under the individual analysis.
Measurement uncertainty values, as applicable, are available upon request.
Tests results relate only to the sample tested. Clients should be aware that a critical step in a chemical or microbiological analysis is the collection of the sample. Unless the sample analyzed is truly representative of the bulk of material involved, the test results will be meaningless. If you have questions regarding the proper techniques of collecting samples, please contact us. We cannot be held
responsible for sample integrity, however, unless sampling has been performed by a member of our staff.
This report shall not be reproduced except in full, without the written approval of the laboratory.
Times are local to the area of activity. Parameters listed in the 40 CFR Part 136 Table II as “analyze immediately” are not performed within
15 minutes.
