CATLIN Project No. 220001 February 2021
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: System completely off as of November 19, 2020. 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 most of the total fluids pumps was suspended on August 10, 2017. In August 2017, the remedial system was only
partially running with N2RW13, N2RW14, N2RW16 and N2RW17 having
operating pumps. Passive recovery of free-phase product was now occurring as of August 2017. The above-stated pumps were turned off and the system was completely shut down on November19, 2002 due to lack of any product recovery from the system. Passive recovery of product continues at the site.
Type: Historically product removal via skimmer and total fluids pumps; currently
only passive recovery of product. Progress: Free product removal underway Construction Contractor: SDC

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
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
MCAS Cherry Point FY-20; 220001VOL1.RPT46 CATLIN Engineers and Scientists
CATLIN Project No. 220001 February 2021
N2RW17 only) and passive recovery efforts. No groundwater sampling was
conducted during the First Semester 2019 at the subject site. However, another
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.

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 were planned to
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 was recommended to turn this
system off completely in the Second Semester 2020. Select on-site wells would
continue to be gauged monthly to track any product migration and thickness increases. If it appears that contamination was migrating, a portion of the recovery system could be reactivated if deemed necessary.
Current: During the Second Semester 2020 (July to December) monthly
gauging events, free-phase product was detected in six wells (N2GW18, N2GW53, N2GW75, N2PR47, N2UKN7 and N4GW12). The in-well thicknesses of product ranged from 0.01 feet to 0.27 feet. 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.
In August 2020, 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 do not appear to be migrating significantly.
Due to the lack of any product recovery from the active system, it was shut down
completely on November 19, 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. In addition, passive product recovery
efforts will continue for the First Semester 2021.
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. In November 2020 the NCDEQ
Division of Water Resources (DWR) approved a pilot test for a surfactant
surging/AFVR event. However, the well planned for the pilot test currently does not have measurable free-phase product. Therefore, the pilot test will be conducted on a well that currently contains measurable product; however, the NCDEQ DWR will need to approve the modification to which well will be utilized
for the pilot test. The pilot test is planned to be conducted in the First Semester
2021. In addition, the next annual groundwater sampling event is scheduled for August 2021.

Notes: 1. COD = Chemical Oxygen Demand
2. TSS = Total Suspended Solids
3. TTO = Total Toxic Organics
4. TTO value is the calculated sum of EPA Methods 608, 624 and 625 constituent concentrations
5. mg/L = milligrams per liter
6. ug/L = micrograms per liter
7. ng/L = nanograms per liter
8. NTU = Nephelometric Turbidity Units
9. NA = Not Analyzed
10. Shaded concentrations indicate exceedance of Waste Water Treatment Standards
11. A zero (0) in the results column indicates concentration is either below detection limit or below quantitation limit

SITE 133SM 6200B COLORIMETRY AND PLUME IN EXCESS OF 2L - UST COMPOUNDS AS OF AUGUST/SEPTEMBER 2020 -UPPER SURFICIAL AQUIFER
1. The sampling frequency for this site is Annual and the next sampling event is scheduled for August 2021.
2. 2L Standard refers to North Carolina Groundwater Quality Standard 15A NCAC 2L.0202.
3. GCL refers to Gross Contaminant Level as defined in "Guidelines for Assessment and Corrective Action for UST Releases" July 15, 2008 Version, change 3 Effective December 1, 2013.
4. A 2L Standard of "0.00" implies a standard has not yet been established. According to NCAC T15:02L, any compound found above laboratory detection limits is considered non-compliant unless otherwise specified by the NCDEQ.
5. The groundwater contaminant boundary depicted on this Figure is based on the GCL list negotiated between the NCDEQ and the MCASCP EAD (letter dated January 15, 2008). Groundwater wells depicted as "blue" and data shaded with "blue" in the table exceed the NC 2L Standard for Non-UST compounds only.
