INTRODUCTION
The purpose of this Periodic Monitoring Report is to present the results of recent monitoring
events performed at petroleum release sites located at Marine Corps Air Station Cherry Point
(MCAS Cherry Point). Monitoring and reporting is being performed in accordance with the
MCAS Cherry Point UST Closure and Management Program adopted by MCAS Cherry Point
Environmental Affairs Department. A listing of sites for which sampling results are included in
this Periodic Monitoring Report is presented in Table I and locations of these sites are shown
on Figure I and Figure II.
This Periodic Monitoring Report is designed such that all data and information pertaining to any
individual site is contained entirely within one section of the report and each section is devoted
entirely to one site. Therefore, each section serves as a stand-alone monitoring report for the
respective site. Each section begins with an Executive Summary which provides information
about location, monitoring, groundwater hydraulics, free-phase product plumes, dissolved-
phase plumes, potential receptors, and remediation at the site. Each Executive Summary is
supported by several site-specific tables and figures.

4.5 DISSOLVED-PHASE PLUME
Plume Concentrations: See Tables 4.2A through 4.3B.
Plume Size and Location: See Figures 4.2 and 4.3.
Significant Changes from Previously Reported Data:
EPA Method 602 by SM 6200B
During the previous (September 2019) monitoring event, monitoring wells
41GW25, 41PR101 and 41PR230 revealed Benzene concentrations exceeding
the 2L Standard. Monitoring wells 41GW25 and 41PR230 revealed Benzene
concentrations exceeding the 2L Standard during the current March 2020
monitoring event. The five monitoring wells that contained free-phase product
are also considered non-compliant. The EPA Method 602 plume has been
modified to more accurately represent boundaries of the current monitoring
event’s free-phase product and analytical data. See Tables 4.2A through 4.2B
and Figure 4.2.
EPA Method 610 by EPA Method 625 / EPA Method 8260B
During the previous (September 2019) monitoring event, monitoring wells
41GW25, 41GW36, 41GW64, 41PR75, 41PR76, 41PR83, 41PR101, 41PR200,
41PR203, 41PR218 and 41PR230 revealed concentrations of Naphthalene
exceeding the 2L Standard. In addition, concentrations of 2-Methylnaphthalene
exceeded the 2L Standard in monitoring wells 41GW25, 41GW36, 41GW64, and
41PR230. During the current (March 2020) monitoring event, 41GW25,
41GW36, 41GW64, 41PR75, 41PR76, 41PR79, 41PR83, 41PR200, 41PR203,
41PR218 and 41PR230 revealed concentrations of Naphthalene exceeding the
2L Standard. Concentrations of 2-Methylnaphthalene also exceeded the 2L
Standard in monitoring wells 41GW36, 41GW64, 41PR200 and 41PR218.The
five wells that contained free-phase product are also illustrated as non-compliant
with the 2L Standards. The EPA Method 610 plume has been modified to more
accurately represent the boundaries of the current monitoring event’s free-phase
product and analytical data. See Tables 4.3A through 4.3B and Figure 4.3.

4.9 OBSERVATIONS AND COMMENTS
Historical: In late 2010/early 2011, CATLIN recommended surfactant
injection/extraction recirculation to remove the remaining free-phase product at
the site. Injection permitting discussions prompted a meeting with the NCDEQ
UIC Injection Branch, to discuss the possibility of a Base Wide re-circulation
permit for MCAS Cherry Point.
Further evaluations and discussions prompted CATLIN to recommend a series
of surfactant recirculation events on site, utilizing a mobile surfactant
injection/recirculation trailer unit. A demonstration of the mobile trailer unit was
performed by a private vendor on May 13th, 2011.
In August 2011, CATLIN developed and Cherry Point EAD submitted the CAPA
report to the Washington Regional office of NCDEQ for the surfactant
recirculation events to be implemented at the subject site. The CAPA was
approved by NCDEQ on November 16, 2011. In January 2012, a Base-Wide
Non-Discharge permit with Building 1083 Site Specific Attachments was
submitted to NCDEQ UIC Branch. The permit was issued on April 6, 2012.
CATLIN prepared and submitted a Workplan in July 2012 and MCAS ordered
the mobile trailer system. The mobile surfactant trailer for MCAS Cherry Point
was delivered in early August 2012.
In late July/early August 2012, CATLIN installed 18 additional recovery wells to
be used in the surfactant recirculation activities at three areas on-site (Area A, B
and C). All additional recovery wells were installed prior to the mobile surfactant
injection/recirculation system start-up. Field activities began in August 2012 and
one round of surfactant recirculation and nutrient injection was completed at
Areas A, B, and C by November 2012. From early January 2013 through early
March 2013 a second round of surfactant recirculation and nutrient injection was
completed at Areas A, B, and C. Gauging data collected from March 2013
through May 2013 revealed free-phase product reappeared at Areas A and B.
As free-phase product remained at Areas A and B as of June 2013, a third round
of surfactant recirculation and nutrient injection was completed at Areas A and B
from July 2013 through October 2013.
Gauging data from the First Semester 2014 revealed that minor amounts of free-
phase product remained at two areas (Area A and B); therefore, an additional
MCAS Cherry Point FY-20; 220001VOL1.RPT45 CATLIN Engineers and Scientists
CATLIN Project No. 220001 August 2020
surfactant recirculation event was recommended. Also, AFVR events were
conducted in May 2014 at the areas of “outlying” free-phase product (i.e. beyond
the limits of Areas A, B and C) at wells 41GW05, 41GW43, 41PR68 and
41PR83. However, no measureable thickness of free-phase product was
recorded from any of these wells during the AFVR events.
Gauging data from the Second Semester 2014 indicated that free-phase product
thicknesses rebounded slightly at two areas (Area A and B) since the last
surfactant recirculation event; therefore, an additional surfactant recirculation
event was planned for the Spring/Summer of 2015. Also, an additional AFVR
event was conducted in October 2014 at well 41PR83 which was calculated to
have recovered less than a hundredth of a gallon of free-phase product. In
addition, in December 2014 monitoring wells 41GW02 and 41GW03 (Area A)
were removed and replaced with four-inch diameter wells 41GW02R and
41GW03R which should enhance surfactant recirculation/recovery at these
locations during the planned, upcoming activities.
The fourth round of surfactant recirculation at Area A commenced on May 5,
2015 and was completed on May 19, 2015. Surfactant recirculation activities
began at Area B in early June 2015; however, due to a construction project in
the vicinity of Area B the surfactant recirculation activities had to be suspended.
The construction project was completed and the surfactant recirculation activities
were restarted in this area in mid-July 2015. The surfactant recirculation
activities were completed at Area B in mid-November 2015. Gauging data from
the Second Semester 2015 revealed that free-phase product rebounded at one
well at Area A and three wells at Area B revealed free-phase product in
November and December 2015.
Quarterly groundwater sampling events were conducted in February 2016 and
May 2016 in accordance with the Non-Discharge Permit associated with the
surfactant recirculation project at the subject site. The results from these
sampling events (and review of historical sampling events over the past five
years) indicated that dissolved-phase contaminant concentrations remained
relatively unchanged and the dissolved-phase plume is generally stable and not
migrating. However, residual free-phase product continued to persist at the
subject site and additional surfactant recirculation events are not planned at this
time.
Residual free-phase product continued to persist at the subject site based on
gauging data from the Second Semester 2016. A project to fully delineate the
extent of residual free-phase product and dissolved-phase groundwater
contamination started in August 2016 and was completed in May 2017. As part
of this project all on-site monitoring wells (approximately 100) were sampled for
Naphthalene in August 2016. The results of this sampling indicated that the
dissolved-phase Naphthalene plume was generally delineated. The data also
indicated that the highest Naphthalene concentration was 428 ug/L which was
above the 2L GWQS of 6 ug/L but well below the GCL of 6,000 ug/L.
As part of the above-stated delineation project 23 borings and temporary wells
were installed, gauged and sampled during March through May 2017. The
MCAS Cherry Point FY-20; 220001VOL1.RPT45 CATLIN Engineers and Scientists
CATLIN Project No. 220001 August 2020
results from the sampling of the temporary wells were used in conjunction with
the August 2016 site-wide Naphthalene data to fully delineate the dissolved-
phase plume. Also, select on-site wells were sampled in February 2017 and
these results were comparable to the August 2016 analytical results. The
borings/temporary wells were also used to delineate the extent of the residual
free-phase product at the subject site. All of the data collected from the above-
stated project was utilized to develop an updated Conceptual Site Model for the
site which was completed in May 2017. Based on the updated Conceptual Site
Model it was determined that a petroleum vapor intrusion investigation was
necessary.
The above-stated vapor intrusion investigation was conducted in November
2017 which consisted of exterior shallow and deep soil gas sampling. The
results from the November 2017 soil gas sampling event revealed detections of
certain petroleum constituents; however, due to elevated laboratory detection
limits for some of the petroleum constituents and other site issues it was decided
that a second phase of exterior soil gas sampling was necessary. Also, select
on-site wells were sampled in August 2017 and these results were comparable
to the February 2017 analytical results. The dissolved-phase contaminant
concentrations were fairly consistent (i.e. no significant increases or decreases)
and the plumes were generally stable.
The above-stated, second phase of exterior soil gas sampling was conducted in
the First Semester 2018 to confirm and verify the results of the first phase of
exterior soil gas sampling. The results from the January 2018 sampling event
revealed that no compounds were above the NCDEQ Residential Vapor
Intrusion Screening Levels. Therefore, no additional vapor intrusion
investigation was proposed at this time.
Select on-site wells were sampled in both the First Semester 2018 (February
2018) and Second Semester 2018 (August 2018) and both sets of these results
were comparable to the August 2017 analytical results. The dissolved-phase
contaminant concentrations were fairly consistent (i.e. no significant increases or
decreases) and the plumes were generally stable. Please note, the PAHs
detected in well 41PR81 during the August 2018 sampling event appear to be an
anomaly as these compounds have not been consistently detected.
Select on-site wells were sampled again in the First Semester 2019 (February
2019) and these results were comparable to the 2018 analytical results. The
dissolved-phase contaminant concentrations were still consistent (i.e. no
significant increases or decreases) and the plumes were generally stable.
Please note, there were no PAHs detected in well 41PR81 during the February
2019 sampling event which appears to confirm that the detection of these
compounds during the August 2018 sampling event was an anomaly.
Select on-site wells were sampled again in the Second Semester 2019 (August
2019) and these results were consistent with the historical analytical data. A
statistical review of the analytical results of the past five years indicated that
contaminant concentrations are generally stable. Therefore, based on the large
volume of historical data documenting this stable trend, it was recommended
MCAS Cherry Point FY-20; 220001VOL1.RPT45 CATLIN Engineers and Scientists
CATLIN Project No. 220001 August 2020
that the sampling frequency for the subject site be reduced from semi-annual to
annual.
Current: Select on-site wells were sampled again in the First Semester 2020
(February 2020) and these results were consistent with the historical analytical
data. A statistical review of the historical analytical results indicates that
contaminant concentrations are generally decreasing or stable and the plumes
are not migrating. The recommendation to modify the sampling frequency to
annual was approved by the NCDEQ WaRO on June 9, 2020 via email.
Therefore, select on-site wells will be sampled again in November 2020.
The main regulatory driver at the subject site is the remaining, residual free-
phase product at the subject site. The above-stated updated Conceptual Site
Model will be utilized to develop a revised remediation plan for the remaining
free-phase product. Ultimately, a more aggressive remediation approach (such
as excavation) may be implemented to address the residual free-phase product
at the subject site. In the interim, passive recovery and/or AFVR events may be
conducted to recover free-phase product.
