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.

Track migration and/or volume reduction of free-phase product plume. 5.2.5 Site Monitoring Status at Time of This Event: Interim and product recovery monitoring. 5.3 Groundwater Hydraulics 5.3.1 Hydraulic Conductivity: 7.0 feet/day 5.3.2 Effective Porosity: 0.25 5.3.3 Hydraulic Gradient: 0.0027 feet/feet 5.3.4 Average Linear Groundwater Flow Velocity: 0.0743 feet/day 5.3.5 Groundwater Flow Direction: East-Northeast. See Figure 5.1 5.3.6 Range of Measured Water Table Elevations: Ranges from -1.79 feet in well 41PR99 to 9.31 feet in well 41GW30 during the First Semester 2017 sampling event. See Tables 5.1A. 5.3.7 Significant Changes from Previously Reported Data: None. 5.4 Free Product Plume 5.4.1 Free Product Present?: Yes 5.4.2 Free Product Thickness Measured: During the First Semester 2017 sampling event, 100 wells were gauged. Of these, six (6) wells contained free product with free product thicknesses ranging from 0.01 feet in wells 41PR202 to 0.05 feet in monitoring well 41PR220. See Tables 5.1A through 5.1B. 5.4.3 Plume Size and Location: See Figure 5.1. 5.4.4 Free Product Removed from Site This Period: None. 5.4.5 Significant Changes from Previously Reported Data: Overall a reduction in the MCAS Cherry Point FY-17; 217001VOL1.RPT39 CATLIN Engineers and Scientists CATLIN Project No. 217001 August 2017 extent and thickness of free-phase product has been observed in the areas which 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 First Quarter (February 2016) monitoring event, concentrations of Benzene exceeding the 2L Standard were revealed in monitoring wells 41GW02R, 41GW25, 41GW36, 41PR82, 41PR203, 41PR212, 41PR220 and 41PR230. Monitoring wells 41GW02R, 41GW25, 41GW36, 41PR79, 41PR82, 41PR203, 41PR220 and 41PR230 exhibited concentrations of Benzene exceeding the 2L Standard during the Second Quarter (May 2016) monitoring event. During the previous Second Semester (August 2016) monitoring event, no samples were analyzed for EPA 602 constituents. During the current (February 2017) monitoring event, samples were again analyzed for EPA Method 602 by SM 6200B and monitoring wells 41GW25, 41GW113 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 Second Semester (August 2016) monitoring event, no samples were analyzed for EPA 610 constituents. Instead, EPA Method 8260B was used to analyze for Naphthalene only. These results revealed Naphthalene concentrations exceeding the 2L Standard in monitoring wells 41GW02R, 41GW03R, 41GW06, 41GW25, 41GW32, 41GW36, 41GW64, 41GW106, 41PR76, 41PR79, 41PR81, 41PR82, 41PR200, 41PR201, 41PR203, 41PR210, 41PR211, 41PR212, 41PR213, 41PR214, 41PR215, 41PR220, 41PR221 and 41PR230. During the current (February 2017) monitoring event, samples were again 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. In addition, the 6 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.

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 MCAS Cherry Point FY-17; 217001VOL1.RPT39 CATLIN Engineers and Scientists CATLIN Project No. 217001 August 2017 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 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. MCAS Cherry Point FY-17; 217001VOL1.RPT39 CATLIN Engineers and Scientists CATLIN Project No. 217001 August 2017 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. Current: 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. The updated Conceptual Site Model will be utilized to evaluate potential remedial alternative technologies for the subject site. Also, based on the updated Conceptual Site Model it was determined that a petroleum vapor intrusion investigation is necessary. This investigation will be conducted at the subject site during the Second Semester 2017. Also, another semi-annual groundwater sampling event of select on-site monitoring wells is planned in August 2017.
