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.

See Tables 6.1A and 6.1B. 6.4.3 Plume Size and Location: See Figure 6.1 6.4.4 Free Product Removed from Site This Period: None. 6.4.5 Significant Changes from Previously Reported Data: Free product continues to be present in monitoring well 59GW26. 6.5 Dissolved-Phase Plume 6.5.1 Plume Concentrations: See Tables 6.2A through 6.4B. 6.5.2 Plume Size and Location: See Figures 6.2A through 6.4B. 6.5.3 Significant Changes from Previously Reported Data: EPA Method 602 by SM 6200B Upper Surficial Aquifer During the Fourth Quarter 2013 (November 2013), shallow monitoring wells were sampled and monitoring well 59GW08 revealed concentrations of Benzene exceeding the 2L Standard. Shallow monitoring wells were also sampled during the Second Semester 2015 (September 2015) monitoring event and no EPA Method 602 contaminant concentrations were detected above 2L Standards. Lower Surficial Aquifer During the Third Quarter 2013 (August 2013) deep wells were sampled and no EPA Method 602 contaminant concentrations were detected above 2L Standards. Deep monitoring wells were also sampled during the Second Semester 2015 (September 2015) monitoring event and again no EPA Method 602 contaminant concentrations were detected above 2L Standards. EPA Method 602 plume boundaries have been modified based on the current monitoring event’s analytical data. See Tables 6.2A through 6.2C and Figures 6.2A and 6.2B. EPA Method 610 by EPA Method 625 Upper Surficial Aquifer During the Fourth Quarter 2013 (November 2013) and again during the Second Semester 2015 (September 2015), shallow monitoring wells were sampled and Naphthalene concentrations exceeding the 2L Standard were revealed in monitoring well 59GW26 during both events. Lower Surficial Aquifer During the Third Quarter 2013 (August 2013) deep wells were sampled and concentrations of Naphthalene above the 2L Standard were revealed in MCAS Cherry Point FY-15; 215001VOL1.RPT36 CATLIN Engineers and Scientists CATLIN Project No. 215001 February 2016 monitoring wells 59GW13, 59GW33, 59GW35 and 59GW41. Deep monitoring wells were also sampled during the Second Semester 2015 (September 2015) monitoring event and Naphthalene concentrations exceeding the 2L Standard were revealed in monitoring wells 59GW13, 59GW33 and 59GW41. EPA Method 610 plume boundaries have been modified based on the current monitoring event’s analytical data. See Tables 6.3A through 6.3B and Figures 6.3A and 6.3B. MADEP VPH/EPH (MADEP VPH/EPH analysis was first implemented in the First Semester 2013.) Upper Surficial Aquifer Shallow wells were sampled during the Fourth Quarter 2013 (November 2013) monitoring event and monitoring wells 59GW08, 59GW10, 59GW25, 59GW26 and 59GW31 revealed MADEP VPH/EPH contaminant concentrations exceeding the 2L Standard. During the Second Semester 2015 (September 2015) monitoring event, shallow wells were also sampled and only monitoring wells 59GW26 and 59GW31 revealed contaminant concentrations exceeding the 2L Standards. Lower Surficial Aquifer During the Third Quarter 2013 (August 2013) and Second Semester 2015 (September 2015) sampling events, deep wells were sampled and results revealed MADEP VPH/EPH contaminant concentrations above the 2L Standards in wells 59GW13, 59GW33, and 59GW41 during both events. MADEP VPH/EPH plume boundaries have been modified based on the current monitoring event’s analytical data. See Tables 6.4A through 6.4B and Figures 6.4A and 6.4B. Please note that site monitoring wells were not sampled if they were inaccessible or found to contain free product. 6.6 Remedial System Air Monitoring Data and Effluent Discharge Data 6.6.1 Air Contaminant Concentrations: Not Applicable 6.6.2 Effluent Discharge Contaminant Concentrations: Not Applicable 6.7 Potential Receptors 6.7.1 Contaminated Water Supply Well(s)?: No 6.7.2 Potable Water Supply Well Within 1,000 Feet of Source Area?: No 6.7.3 Any Water Supply Well Within 250 Feet of Source Area?: No 6.7.4 Surface Water Body Within 500 Feet?: No 6.7.5 Past Evidence of Vapors?: No 6.7.6 Significant Changes from Previously Reported Data?: None MCAS Cherry Point FY-15; 215001VOL1.RPT36 CATLIN Engineers and Scientists CATLIN Project No. 215001 February 2016 6.8 Remediation 6.8.1 Status: System shut down January 17, 2013 to facilitate site closure. AFVR events conducted: June 24, 2014; October 29, 2014; December 11, 2014 and April 7, 2015. 6.8.2 Type: SVE; free-phase product removal via two solar skimmer pumps. AFVR. 6.8.3 Progress: System shut down to facilitate site closure 6.8.4 Construction Contractor: Shaw 6.8.5 Operating Contractor: SDC Group, Inc./GES 6.9 Observations and Comments 6.9.1 Historical: The SVE system was shut down on January 17, 2013 to determine if free-phase product would reappear (last detection was June 2012). Gauging data from January through June 2013 indicated no recurrence of free-phase product. Quarterly closure sampling was initiated in February and May 2013 at the subject site. Gauging data from July through December 2013 indicated no recurrence of free-phase product. Also, quarterly closure sampling was continued in August and November 2013. Analytical results from the four quarters of closure sampling indicated no exceedances of the GCLs and contaminant concentration trends were stable. Therefore, “No Further Action” status was recommended for the subject site. Gauging data from January 2014 again indicated no recurrence of free-phase product. Therefore, CATLIN completed and MCAS Cherry Point submitted a Site Closure Report in April 2014 to the NCDEQ which requested that the site be designated as “No Further Action” status with a Notice of Residual Petroleum for soil and groundwater. In May 2014 the NCDEQ responded by approving the site closure request. In anticipation of site closure activities (i.e. monitoring well abandonment), SDC/GES was tasked to gauge the wells at the site for one final event. The gauging results from this final event on May 30, 2014 indicated 0.03 feet of free-phase product in well 59GW31. Therefore, site closure activities were halted. An AFVR event was conducted on June 24, 2014 at wells 59GW26 and 59GW31 to address residual levels of free-phase product. Monthly gauging activities continued during the Second Semester 2014 and revealed that free-phase product remained absent at well 59GW31; however, well 59GW26 continued to contain measureable thicknesses of free-phase product (September through December 2014). In October and December 2014 AFVR events were conducted at well 59GW26 and these events recovered approximately 0.6 gallons of free-phase product. During the First Semester 2015 monthly gauging activities revealed that free- phase product was consistently detected in well 59GW26 from January through April 2015. Therefore, an additional AFVR event was conducted at this well on April 7, 2015 which yielded approximately three gallons of free-phase product. Monthly gauging data from May and June 2015 also indicated free-phase product was present in this well. MCAS Cherry Point FY-15; 215001VOL1.RPT36 CATLIN Engineers and Scientists CATLIN Project No. 215001 February 2016 6.9.2 Current: Monthly gauging activities continued in the Second Semester 2015 and revealed that free-phase product continued to persist in well 59GW26. Therefore, an additional AFVR event was attempted in October 2015; however, upon starting the AFVR event the vacuum truck blower failed; therefore, no measureable product was recovered during this event. As free-phase product continues to persist in well 59GW26 alternative remedial approaches are being evaluated. One alternative which may be implemented would be to convert monitoring well 59GW26 to a SVE well and restart the SVE system in an attempt to remediate the residual levels of free-phase product in the area of 59GW26. Also, groundwater sampling had not been conducted at the subject site since August/November 2013. Analytical results from the September 2015 a groundwater sampling event revealed an overall declining trend in contaminant concentrations. As site closure will not be possible within the next year, (due to the continued presence of free-phase product at the subject site) the groundwater sampling frequency will revert to semi-annual (Lower surficial wells to be sampled in February 2016 and upper surficial wells to be sampled in August 2016).
