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.

were remediated by surfactant/recirculation activities. However, areas of residual
free-phase product remain at the subject site.

5.5 Dissolved-Phase Plume

5.5.1 Plume Concentrations: See Table 5.2A through 5.3B.
5.5.2 Plume Size and Location: See Figure 5.2.
5.5.3 Significant Changes from Previously Reported Data:

EPA Method 602 by SM 6200B
During the previous (February 2017) monitoring event, monitoring wells 41GW25,
41GW113 and 41PR230 revealed Benzene concentrations exceeding the 2L
Standard.

During the current (August 2017) monitoring event, monitoring wells 41GW25,
41PR79, 41PR101, 41PR220 and 41PR230 revealed Benzene concentrations
exceeding the 2L Standard. 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 Table 5.2A and 5.2B.

EPA Method 610 by EPA Method 625/ EPA Method 8260B
During the previous (February 2017) monitoring event, samples were analyzed for
EPA 610 constituents and the following wells revealed Naphthalene
concentrations exceeding the 2L Standards: 41GW25, 41GW36, 41GW43,
41GW64, 41PR72, 41PR73, 41PR76, 41PR200, 41PR203 and 41PR230.
Monitoring wells 41GW36, 41GW64 and GWPR76 also revealed concentrations of
2-Methylnaphthalene exceeding the 2L Standards.

During the current (August 2017) monitoring event, samples were again analyzed
for EPA 610 constituents and the following wells revealed Naphthalene
concentrations exceeding the 2L Standards: 41GW25, 41GW36, 41GW64,
41PR72, 41PR75, 41PR76, 41PR78, 41PR79, 41PR83, 41PR101, 41PR200,
41PR203, 41PR220 and 41PR230. Monitoring wells 41GW25, 41GW36,
41GW64, 41PR79 and 41PR220 also revealed concentrations of 2-
Methylnaphthalene exceeding the 2L Standards. In addition, the 3 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 5.3A through 5.3B and Figure 5.2.

Please note that site monitoring/recovery wells were not sampled if they were
inaccessible or found to contain free-phase product.

5.9 Observations and Comments

5.9.1 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
MCAS Cherry Point FY-17; 217001VOL1.RPT40 CATLIN Engineers and Scientists
CATLIN Project No. 217001 February 2018
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
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
MCAS Cherry Point FY-17; 217001VOL1.RPT40 CATLIN Engineers and Scientists
CATLIN Project No. 217001 February 2018
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 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.

5.9.2 Current: 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. Therefore, a
second phase of exterior soil gas sampling is being conducted in the First
Semester 2018 to confirm and verify the results of the first phase of exterior soil
gas sampling. Once this second phase of soil gas sampling is completed a report
of findings will be submitted.

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 are fairly consistent (i.e. no significant increases or
decreases) and the plumes are generally stable. Another semi-annual
groundwater sampling event of select on-site monitoring wells is planned in
February 2018. Also, the updated Conceptual Site Model, mentioned above, will
be utilized to evaluate potential remedial alternative technologies to address the
residual free-phase product at the subject site.
