1.0 INTRODUCTION
This report summarizes the semiannual groundwater monitoring activities performed at the
Colonial Pipeline Company (CPC) Kannapolis Booster Station (the Site) located at 9301
Mooresville Road in Concord, North Carolina (Figure 1) from September 2018 through February
2019. This report also describes the remediation systems operations performed during the
reporting period in accordance with the Corrective Action Plans (CAPs) for the Site approved by
the North Carolina Department of Environmental Quality (NCDEQ). Apex Companies, LLC (Apex;
dba Apex Engineering, P.C.) prepared this Semiannual Groundwater Monitoring Report on behalf
of CPC for submittal to NCDEQ.
2.0 PROJECT BACKGROUND
The facility consists of a control building, a switch gear building, eight large electric booster pumps, a
40-inch diameter pipeline for transporting gasoline products (Line 1), a 36-inch diameter pipeline for
transporting kerosene, diesel fuel, and other fuel oil products (Line 2), and two 21,000-gallon above
ground storage tanks and associated above -ground and below -ground piping and valves. The
facility has been in operation since the 1970s.
2.1 Historic Site Impacts
Formal assessment and remediation activities were initiated at the facility in 1995. Three areas of
concern were identified at the facility including: (i) the Line 2 Manifold Area; (ii) the Line 1 Manifold
Area; and, (iii) the Line 1 Pig Signal Area. Impacts identified during the 1995 assessment are
included in Incident Number 14414 (Figure 2).
Petroleum impacts in the Line 2 Manifold Area were the result of a kerosene release. Excavation of
impacted soils were limited due to the presence of pumps, footings, and associated underground
piping and valves. A light non -aqueous phase liquid (LNAPL) recovery system and a soil vapor
extraction (SVE) system were installed and formerly operated in this area.
A dissolved phase plume consisting of gasoline -related compounds was identified in the Line 1
Manifold Area. A limited amount of impacted soil was excavated in this area and an SVE system
was installed and formerly operated in the Line 1 Manifold Area.

Colonial Pipeline Company, Kannapolis Booster Station Page 2
Gasoline impacted soil was also identified in the Line 1 Pig Signal Area as a result of a release from
a leaking pipe fitting. Approximately 1,000 tons of soil was excavated and thermally treated from this
area. The excavation extended to bedrock, removing the source material; however, the release
resulted in dissolved phase groundwater impacts. An air sparge trench located near the
downgradient property boundary and a non -discharge pump and treat system were installed in the
late-1990s to prevent off -Site migration of petroleum hydrocarbons.
The air sparge trench is currently in operation. The groundwater pump and treatment system were
taken off-line in 2010, following approval from NCDEQ on April 12, 2010. The LNAPL recovery and
SVE systems were taken off-line in 2010, following approval from NCDEQ on September 29, 2010.
2.2 Recent Site Impacts
A 920-gallon petroleum release occurred at the Site on March 13, 2015 when a valve gasket failed
near the Line 2, Unit 4 booster pump. Emergency response and abatement activities were
performed from March 13, 2015 through August 11, 2015. On August 13, 2015, a three -quarter -inch
nipple on Line 2 was struck by a piece of equipment during backfilling operations resulting in a 5,000-
gallon petroleum release over the recently remediated area. Approximately 4,750-gallons of diesel
fuel were recovered during initial response activities and subsequent recovery well evacuation
efforts. Residual soil impacts were detected at areas where additional excavation was not feasible
due to the presence of booster pumps, footings, and associated underground piping and valves.
Approximately 750 tons of petroleum -impacted soil were removed from the release area during the
initial response activities associated with both 2015 releases. Impacts identified during the 2015
assessment are included in Incident Number 91340.
A CAP and CAP Addendum were submitted to NCDEQ on April 15, 2016 and July 12, 2016,
respectively. The CAP documents specify installation and operation of a bio-venting and bio-sparge
system to address residual soil impacts and dissolved phase groundwater impacts. The CAP was
approved on May 6, 2016 and the CAP Addendum was approved on July 28, 2016. The semiannual
groundwater monitoring program for the Site incorporates the groundwater monitoring programs
associated with Incident Numbers 14414 and 91340. A summary of the Groundwater Monitoring
Program for the Site is provided as Table 1.

3.0 FIELD ACTIVITIES
3.1 Groundwater Gauging
Prior to sampling, groundwater monitoring wells were gauged to measure the depth to groundwater
and LNAPL, if present. Upon arriving at the Site, wells were opened and allowed to equilibrate.
Wells were gauged in accordance with the United States Environmental Protection Agency
(USEPA) Region IV Science and Ecosystem Support Division Field Branches Quality System and
Technical Procedures. The wells were gauged in order of potential impact, moving from
upgradient wells, to downgradient wells and finally source area wells. Depths to groundwater and
LNAPL were measured using an electronic oil/water interface probe capable of measuring to an
accuracy of 0.01 feet. The interface probe was thoroughly decontaminated before collecting
measurements at each subsequent monitoring well. A total of 10 monitoring wells (MW-1, MW-4,
MW-5, MW-6, MW-8, MW-13, MW-23, MW-24, MW-25, and MW-25D) and 11 recovery wells (SB-
4, S13-6, S13-8, S13-9, SB-10, S13-11, S13-12, SB-15, SB-16, S13-18, and RW-1) were gauged during
the February 2019 monitoring event. Two recovery wells (SB-14 and RW-2) were not able to be
located. The location of each monitoring well is shown on Figure 2 and the location of each
recovery well is shown on Figure 3.
3.2 Groundwater Sampling and Analysis
Groundwater samples were collected from seven monitoring wells (MW-4, MW-6, MW-8, MW-13,
MW-24, MW-25, and MW-25D) during the February 2019 monitoring event. At each monitoring well,
a baseline set of water quality stabilization data were measured (temperature, pH, specific
conductance, and oxidation reduction potential), and recorded. The total volume of water in each
well was calculated and approximately three well volumes were purged from each well prior to
collecting each sample. All monitoring wells were purged and sampled with disposable bailers.
Groundwater sampling logs documenting the groundwater purging and sampling are provided as
Appendix A.
After purging an adequate volume of water from each well, a sample was retrieved and transferred
to laboratory supplied, pre -preserved bottleware and immediately placed on ice and maintained at
a temperature of approximately 4 degrees Celsius. Groundwater samples were transported under
standard chain -of -custody procedures to Shealy Environmental Services, Inc. of West Columbia,
South Carolina. Groundwater samples collected from monitoring wells MW-4, MW-6, MW-8, and
MW-13 were analyzed for benzene, toluene, ethylbenzene, and xylenes (BTEX) and methyl tert-

butyl ether (MTBE) by Environmental Protection Agency (EPA) Method 602 — purgeable aromatics
SM 6200B. Groundwater samples collected from monitoring wells MW-24, MW-25, and MW-25D
were analyzed for BTEX by EPA Method 602 — purgeable aromatics SM 6200B; semi -volatile
organic compounds by EPA Method 625; and Massachusetts Department of Environmental
Protection (MADEP) extractable petroleum hydrocarbons (EPH) and volatile petroleum
hydrocarbons (VPH) in consideration of the diesel releases that occurred on March 13, 2015 and
August 13, 2015.
4.0 FINDINGS
4.1 Well Gauging Results and Groundwater Flow
Depth to water and top of well casing elevation data from the monitoring wells were used to
calculate groundwater elevations relative to an on -Site benchmark referenced to mean sea level
datum. LNAPL was not detected in any of the monitoring wells during this sampling event. A
summary of monitoring well gauging data is provided in Table 2.
A groundwater potentiometric map for the surficial unit using water level elevation data from the
February 2019 sampling event is provided as Figure 4. The potentiometric map depicts the
direction of groundwater flow to the southeast. A hydraulic gradient of approximately 0.04 feet per
foot was measured between the 720 feet potentiometric contour line near MW-23 and the 705 feet
potentiometric contour line near MW-8. Groundwater flow patterns observed in February 2019 are
consistent with historic sampling events.
LNAPL was detected in 1 of the 13 recovery wells during the February 15, 2019 sampling event at
SB-16 at a thickness of 0.02 feet. A summary of recovery well gauging data is provided as Table
3.
4.2 Groundwater Analytical Results
Groundwater sampling activities performed at the Site focused on collecting analytical data from
the upgradient, downgradient, and central plume areas to evaluate Constituents of Concern (COC)
trends over time. The analytical results for groundwater samples collected during this monitoring
period were compared to the 15A NCAC 2L .0202 Groundwater Quality Standards (21L Standards)
and to the 15A NCAC 2B .0215 Surface Water Standards (213 Standards) for a Water Supply II,
High Quality Waters surface water classification following the Risk Based Corrective Action Rules

for non -UST releases of petroleum under North Carolina House Bill 765. A groundwater
concentration map showing the concentrations of benzene in groundwater monitoring wells during
the February 2019 sampling event is provided as Figure 5. Laboratory analytical reports and
chain -of -custody records for the groundwater samples are presented in Appendix B.
The February 2019 groundwater sampling results indicate that the hydrocarbon plume is generally
stable; however, concentrations of benzene in MW-13, and benzene, C5-C8 Aliphatics, C9-C-18
Aliphatics, and C9-C22 Aromatics in MW-24 were elevated compared to those recorded during
recent sampling events. A summary of groundwater analytical results is provided in Table 4.
Notable results from the February 2019 sampling event are summarized below:
■ Benzene was detected in MW-13 (48 pg/L) and in MW-24 (13 pg/L) above the 2L and 2B
Standards of 1.0 pg/L and 1.19 pg/L, respectively. A concentration time trend graph for
benzene in MW-13 is included as Appendix C
■ MTBE was detected in MW-8 (10 pg/L) and MW-13 (2.7 pg/L) during the sampling event.
Concentrations were below the 2L and 2B Standards of 20 pg/L and 19 pg/L, respectively.
■ Ethylbenzene (1.6 and 14 pg/L), toluene (1.4 and 3.3 pg/L), and xylenes (2.0 and 7.4 pg/L)
were detected in MW-13 and MW-24 at concentrations below their respective 2L and 2B
Standards.
■ Acenaphthene (7.0 pg/L), anthracene (estimated concentration of 2.9 pg/L), fluoranthene
(7.9 pg/L), phenanthrene (estimated concentration of 2.3 pg/L), and pyrene (6.2 pg/L) were
detected in MW-24 during the sampling event at concentrations below their respective 2L
and 2B Standards.
■ EPH and VPH were detected in MW-24 during the sampling event. Hydrocarbon fractions
C9-C12 Aliphatics were detected at a concentration of 400 pg/L, above the 2B Standard of
180 pg/L. Hydrocarbon fractions C9-C18 Aliphatics were detected at a concentration of
260 pg/L, above the 2B Standard of 180 pg/L. Hydrocarbon fractions C5-C8 Aliphatics
were detected at a concentration of 1,900 pg/L, above the 2L and 2B Standards.
Hydrocarbon fractions C9-C10 Aromatics were detected at a concentration of 520 pg/L and
C11-C22 Aromatics were detected at a concentration of 320 pg/L, exceeding their
combined 2L Standard of 200 pg/L.

5.0 REMEDIATION SYSTEM PERFORMANCE
5.1 Air Sparge Trench Remediation System
The air sparge trench remediation system was brought on-line in June 1998 to treat shallow
groundwater prior to migration off -Site. The air sparge system continues to operate to aid in the
removal of benzene and MTBE from groundwater in the vicinity of well MW-8 and MW-13. The air
sparge trench operated continuously during the reporting period; however, it was shut down
approximately two weeks prior to the February 15, 2019 groundwater sampling event to allow for
collection of representative groundwater samples.
5.2 Bio-Sparge and Bio-Venting Systems
The bio-sparge and bio-venting systems were brought on-line on March 7, 2017 to address soil
and groundwater impacts associated with the 2015 diesel fuel releases. The bio-sparge system
ran continuously during the reporting period. The bio-venting system ran approximately 50% of the
time during the reporting period due to excessive water recovery due to prolonged wet weather
conditions resulting in a wetting front moving downward through the soil column. The bio-sparge
and bio-venting systems were shut down approximately two weeks prior to the February 15, 2019
groundwater sampling event to allow for collection of representative groundwater samples.
6.0 CONCLUSIONS AND RECOMMENDATIONS
During the February 2019 monitoring event, with the exception of SB-16, residual LNAPL was not
detected in recovery wells installed in response to the 2015 diesel fuel releases. Benzene, C5-Cl8
Aliphatics and C9-C22 Aromatics exhibited concentrations above the applicable 2B and/or 2L
Standards in MW-24. This well is located approximately 360 feet from the surface water body.
These detections are attributed to the 2015 diesel fuel releases. The recently installed bio-sparge
and bioventing system will aid in the removal of these remaining hydrocarbon constituents from the
subsurface. Monitoring wells MW-25 and MW-25D, located nearly 250 feet from the surface water
body, continue to delineate the downgradient boundary of the plume in this area. Both monitoring
wells were free of any detections during the February 2019 sampling event.
Benzene was detected in MW-13 during the February 2019 sampling event at concentrations
greater than the 2L and 2B Standards. Detections of benzene at MW-13 are associated with the
1995 release as historic groundwater analytical data indicates the presence of benzene in this well
``

Semiannual Groundwater Monitoring Report, September 2018 - February 2019 April 1, 2019

since February 1998. Benzene concentrations in MW-13 have generally been decreasing since
1998, with seasonal fluctuations; however, the benzene concentration during the February 2019
sampling event was one order of magnitude higher than the five preceding sampling events. The
concentration time trend graph for benzene in monitoring well MW-13 shows an overall decreasing
concentration trend. Although 2B Surface Water Standards were exceeded in MW-13, any
discharge of the groundwater plume to surface water would not likely contravene the surface water
standards within the surface water body itself.
During the February 2019 sampling event, MTBE was detected in MW-8 (10 pg/L) and MW-13 (2.7
pg/L). Concentrations were below the 2L and 2B Standards of 20 pg/L and 19 pg/L, respectively.
The historic concentration trends of MTBE show a continual decrease in both MW-8 and MW-13.
The air sparge system in the vicinity of wells MW-8 and MW-13 continues to operate and aid in the
removal of benzene and MTBE from groundwater.
Apex proposes that based on the minimal LNAPL detections during the reporting period, and the
generally stable and/or decreasing dissolved phase petroleum concentration trends observed at
the Site since the historic and recent 2015 release incidents, the reporting schedule for the Site be
modified from semiannual to annual. Following NCDEQ approval, one annual report will be
submitted on or before October 1st of each year detailing the semiannual monitoring well sampling
and annual water supply well sampling results. The next semiannual groundwater sampling event
is scheduled to occur in August 2019.

All concentrations reported in micrograms per liter (Ng/L)
MADEP = Massachusetts Department of Environmental Protection
EPH = Extractable Petroleum Hydrocarbons
VPH = Volatile Petroleum Hydrocarbons
WS-II = Water Supply Class II
HQW = High Quality Waters
NE = No standard established
NA = Not analyzed
ND = Not detected
Bold = Detection exceeds North Carolina Administrative Code (NCAC) 2L Groundwater Standard
Gray fill indicates detection above the applicable Surface Water Standards (Indicated with superscript numerals 1 and 2)
No superscript numeral indicates the NCAC 213 Surface Water Standard for Water Supply (WS) ll, High Quality Waters (HQW) classification
(') = Environmental Protection Agency Nationally Recommended Water Quality Criteria for Aquatic Life and Human Health.
