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 Table 4.2A through 4.3B. Plume Size and Location: See Figure 4.2. Significant Changes from Previously Reported Data: EPA Method 602 by SM 6200B During the previous (August 2018) monitoring event, Benzene concentrations
exceeding the 2L Standard were revealed in monitoring wells 41GW25,
41PR101 and 41PR230. During the current February 2019 monitoring event, monitoring wells 41GW25, 41PR200 and 41PR230 contained Benzene concentrations exceeding the 2L Standard. The six 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 (August 2018) monitoring event, the following wells revealed Naphthalene concentrations exceeding the 2L Standards: 41GW25, 41GW36, 41GW43, 41GW64, 41PR75, 41PR76, 41PR78, 41PR79, 41PR101, 41PR200, 41PR203, and 41PR230. Monitoring wells 41GW25, 41GW36, 41GW64 and 41PR200 revealed concentrations of 2-Methylnaphthalene exceeding the 2L
Standards. Monitoring well 41PR81 also revealed concentrations of Benzo(a)anthracene, Benzo(a)pyrene, Benzo(b)fluoranthene, Benzo(k)fluoranthene, and Indeno(1,2,3-cd)pyrene exceeding their respective 2L Standards. These concentrations (with the exception of Benzo(a)anthracene) also exceed their respective GCLs.
During the current February 2019 monitoring event, Naphthalene concentrations exceeding the 2L Standard were revealed in monitoring wells 41GW25, 41GW36, 41GW64, 41PR75, 41PR76, 41PR79, 41PR83, 41PR101, 41PR200, 41PR203, 41PR218 and 41PR230. Monitoring wells 41GW25, 41GW36,
41PR200, 41PR218 and 41PR230 also revealed concentrations of 2-Methylnaphthalene exceeding the 2L Standard. In addition, the six 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. Please note that site monitoring/recovery wells were not sampled if they were inaccessible or found to contain free-phase product.

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
MCAS Cherry Point FY-19; 219001VOL1.RPT43 CATLIN Engineers and Scientists
CATLIN Project No. 219001 August 2019
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 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
MCAS Cherry Point FY-19; 219001VOL1.RPT43 CATLIN Engineers and Scientists
CATLIN Project No. 219001 August 2019
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.
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 are fairly consistent (i.e. no significant increases or decreases)
and the plumes are 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 is 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. Current: 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 are still fairly consistent (i.e. no significant increases or decreases) and the plumes are 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
MCAS Cherry Point FY-19; 219001VOL1.RPT43 CATLIN Engineers and Scientists
CATLIN Project No. 219001 August 2019
anomaly.
Another semi-annual groundwater sampling event of select on-site monitoring wells is planned in August 2019. 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.
