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.

2.8 REMEDIATION

Status: Construction of the horizontal/vertical well system was completed in
May 2007. The horizontal portion of the system has been shut down due to
successful product recovery efforts in the area where the horizontal recovery
wells exist. The skimmer pumps associated with the vertical system were shut
down in the 2nd Semester 2016 due to lack of product recovery. Also, due to
lack of product recovery and excessive system maintenance the use of the total
fluids pumps was suspended on August 10, 2017. Therefore, the remedial
system is now shut down (except only N2RW13, N2RW14, N2RW16 and
N2RW17 have operating pumps) and passive recovery of free-phase product is
now occurring.
Type: Historically product removal via skimmer and total fluids pumps; currently
only passive recovery of product.
Progress: Free product removal underway
Construction Contractor: SDC
Operating Contractor: ITMS/GES

2.9 OBSERVATIONS AND COMMENTS

Historical: CATLIN continues to provide periodic engineering evaluations for
the operation of the treatment system in order to maximize product recovery.
Previously, seven wells with skimmer pumps were converted to total fluids free-
phase product recovery wells in an effort to increase free-phase product
recovery. After installation, the total fluids pumps became inoperable due to back
pressure on the conveyance lines caused by iron fouling. In December 2011,
the conveyance lines were replaced and configured to minimize future back
pressure within the lines.

CATLIN evaluated the effectiveness of the seven free-phase product recovery
pumps and recommended that the entire system be converted into a total fluids
free-phase product recovery system. Additionally, an iron/bacteria sampling
event was conducted at the site in May 2013 to determine the composition and
root cause of the iron fouling issues. Results from this sampling event were
evaluated in the September 2013 Report of Findings. This report recommended
evaluating and pilot testing the most promising cleaning/iron removal
alternatives.

During the Second Semester 2014 over 65 gallons of free-phase product was
recovered at the subject site as opposed to only 27.5 gallons of free-phase
product recovered during the First Semester 2014. The increase in free-phase
product recovery was likely the cleaning and replacement of clogged
conveyance lines due to fouling issues.

During the First Semester 2015 approximately 28 gallons of free-phase product
was recovered at the subject site. During the Second Semester 2015
approximately 15 gallons of free-phase product was recovered at the subject
site. The decrease between semesters was attributable to clogging in the
conveyance lines due to fouling issues.

During the First Semester 2016, 36 gallons of free-phase product was recovered
at the subject site. This increase in recovered product is the result of
implementing passive recovery efforts that began in November 2015. The
majority of the product recovered during the First Semester 2016 was from
passive recovery efforts as the system is still not operating at optimal efficiency.

During the Second Semester 2016, 17 gallons of free-phase product was
recovered at the subject site. The majority of the product recovered during the
Second Semester 2016 was from passive recovery efforts as the system is still
not operating at optimal efficiency. Late in the Second Semester 2016 it was
decided to remove the skimmer pumps due to a lack of product recovery from
these pumps. Therefore, as of the end of the Second Semester 2016 the
system was operating with only the seven wells containing total fluids pumps
which are N2RW15, N2RW16, N2RW17, N2RW25, N2RW26, N2RW31 and
N2RW32.

During the First Semester 2017, only seven gallons of free-phase product was
recovered at the subject site. The majority of the product recovered during the
MCAS Cherry Point FY-20; 220001VOL1.RPT45 CATLIN Engineers and Scientists
CATLIN Project No. 220001 August 2020
semester was from passive recovery efforts. Due to the lack of product recovery
and excessive maintenance time to keep the total fluids pumps operating it was
decided on August 10, 2017 to suspend operation of the total fluids pumps.
Therefore, as of August 10, 2017 only passive recovery of free-phase product
was occurring at the subject site. Also, it should be noted that a review of free-
phase product thicknesses in on-site wells for the past year (August 2016
through June 2017) indicated only minor amounts of product (largest amount
0.61 feet in N2GW53 in March 2017) and thicknesses were generally less than
0.50 feet. In addition, the lateral extent of free-phase product also continued to
indicate a declining trend. However, there were still a few areas at the subject
site where additional product delineation was recommended.

During the Second Semester 2017, 14 gallons of free-phase product was
recovered at the subject site. The product recovered during this semester was
from passive recovery efforts. However, select recovery wells were reactivated
for small scale pilot testing of different recovery techniques for those wells
containing measureable free-phase product.

A project to refine the extent of free-phase product at this site was completed in
November 2017. An updated Conceptual Site Model was prepared which
indicated that the free-phase product and gross contamination was horizontally
and vertically delineated in the majority of the free-phase product areas at the
subject site.

During the First Semester 2018, 16 gallons of free-phase product was recovered
at the subject site. The product recovered during this semester was from
passive recovery efforts. Also, select deep monitoring wells were sampled in
February 2018 and only one well (52GW16) contained petroleum-related
contaminants above the 2L Standards. The groundwater sampling at this site
was historically “split sampled” (i.e. deep wells in February and shallow wells in
August). However, due to the minimal deep, dissolved-phase petroleum
contamination it was proposed that the site sampling frequency be modified to
“Annual” sampling. It was proposed that both shallow and deep wells at the site
would be sampled in August 2018.

During the Second Semester 2018, 27 gallons of free-phase product was
recovered at the subject site. The product recovered during this semester was
mainly from passive recovery efforts. Select shallow monitoring wells were
sampled in August 2018 and results indicated that the dissolved-phase
contamination at the subject site is fairly stagnant and not significantly increasing
or decreasing. Please note, no deep monitoring wells were sampled in August
2018 due to the historical, extremely low contaminant concentrations in these
wells. However, another annual groundwater sampling event is planned for
August 2019 during which both shallow and deep wells will be sampled.

During the First Semester 2019, 48 gallons of free-phase product was recovered
at the subject site. The product recovered during this semester was from both
the total fluids system (operating pumps in N2RW13, N2RW14, N2RW16 and
N2RW17 only) and passive recovery efforts. No groundwater sampling was
conducted during the First Semester 2019 at the subject site. However, another
MCAS Cherry Point FY-20; 220001VOL1.RPT45 CATLIN Engineers and Scientists
CATLIN Project No. 220001 August 2020
annual groundwater sampling event was planned for August 2019 during which
both shallow and deep wells will be sampled.

During the Second Semester 2019, approximately one gallon of free-phase
product was recovered at the subject site. The product recovered during the
current semester was only from passive recovery efforts.

In August 2019, select shallow and deep monitoring wells were sampled. The
analytical results from this sampling indicated that the dissolved-phase
contamination at the subject site were fairly stable and not significantly
increasing or decreasing. Also, the petroleum-related contaminant
concentrations were not approaching any of the established GCLs. In addition,
the dissolved-phase contaminant plumes did not appear to be migrating
significantly.

Current: During the First Semester 2020 (January to June) monthly gauging
events, free-phase product was only detected in two wells (N2RW12 and
N4GW12). In addition, only approximately one gallon of free-phase product was
recovered at the subject site. The product recovered during the current
semester was only from passive recovery efforts. Passive product recovery
efforts will continue for the Second Semester 2020.

Due to the lack of any product recovery from the active system (currently
operating four wells with total fluids pumps), it is recommended to turn this
system off completely in the Second Semester 2020. Select on-site wells will
continue to be gauged monthly to track any product migration and thickness
increases. If it appears that contamination is migrating, a portion of the recovery
system could be reactivated if deemed necessary.

Also, the previously stated, updated Conceptual Site Model will be utilized to
evaluate numerous remediation technologies/alternatives to address the
remaining free-phase product at the subject site. One approach could be to
conduct a well surging/AFVR event at wells containing measurable free-phase
product. Also, the next annual groundwater sampling event is scheduled for
August 2020.
