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.

Source Type(s): JP-5, Varsol, Waste Oil 2.2 MONITORING EVENT INFORMATION Sampling Performed By: ITMS/GES (Annual) Date(s) of This Monitoring Event: 8/27/2019 Date(s) of Previous Monitoring Event: 8/21/2018 and 8/28/2018 Reason(s) for This Monitoring Event: Track migration and/or volume reduction of free-phase product plume. Site Monitoring Status at Time of This Event: Interim and product recovery monitoring. 2.3 GROUNDWATER HYDRAULICS Hydraulic Conductivity: 3.774 feet/day Effective Porosity: 0.33 Hydraulic Gradient: Upper Surficial Aquifer = 0.0025 feet/feet. Lower Surficial Aquifer = 0.0032 feet/feet. Average Linear Groundwater Flow Velocity: Upper Surficial Aquifer = 0.0287 feet/day, Lower Surficial Aquifer = 0.0371 feet/day. Groundwater Flow Direction: Upper Surficial Aquifer =West-Southwest, Lower Surficial Aquifer = Northwest. See Figure 2.1. Range of Measured Water Table Elevations: Ranges from -1.42 feet in well 52GW77 to 13.57 feet in well N4GW04 during the August 2019 monitoring event. See Table 2.1A. Significant Changes from Previously Reported Data: None. 2.4 FREE PRODUCT PLUME Free Product Present?: Yes Free Product Thickness Measured: During the August 2019 annual monitoring event, 206 wells were gauged, of which ten (10) wells contained free- phase product. Free product thicknesses ranged from 0.01 feet in wells N2GW15, N2GW52 and N2RW06 to 0.41 feet in monitoring well N2GW75. See Table 2.1A. Plume Size and Location: See Figure 2.1 Free Product Removed from Site This Period: One gallon or less. Significant Changes from Previously Reported Data: Free-phase product was removed in the areas influenced by the horizontal recovery wells by early MCAS Cherry Point FY-19; 219001VOL1.RPT44 CATLIN Engineers and Scientists CATLIN Project No. 219001 February 2020 2010. Therefore, the horizontal wells were shut down at that time and free- phase product has not returned in these areas. For the other areas of the site; long term historical trends indicate a general declining trend in the extent and thicknesses of product. 2.5 DISSOLVED-PHASE PLUME Plume Concentrations: See Tables 2.2A through 2.3B. Plume Size and Location: See Figures 2.2A through 2.3B. Significant Changes from Previously Reported Data: Method SM 6200B Previously, this site had been sampled semi-annually, with lower surficial monitoring wells being sampled in the first semester monitoring event and the upper surficial monitoring wells sampled during the second semester event. During the First Semester 2018 (February 2018) semi-annual monitoring event (in which only lower surficial monitoring wells were sampled) deep monitoring wells 51EX12, 51EX16 and 52GW16 revealed SM 6200B compound concentrations at levels exceeding 2L Standards, many of which are chlorinated solvents. Only well 52GW16 contained petroleum-related compounds above the 2L Standards. During Second Semester 2018 (August 2018) semi-annual monitoring event (in which only upper surficial monitoring wells were sampled), monitoring wells 42GW05, 52GW28, 52GW33, 52GW35, 52GW41, 52GW82, 52GW84, N2GW06, N2GW20, N2GW23, N2GW24, N2GW25, N2GW26,N2GW27, N2GW30, N2GW31R, N2GW36, N2GW4C, N2GW50, N2GW52, N2GW58, N2GW59, N2GW62, N2GW63, N2GW69, N2GW74, N2GW75, N2GW81, N2GWRW45A, N4GW01, and N4GW07R revealed SM 6200B compound concentrations at levels exceeding 2L Standards, many of which are chlorinated solvents. During the Second Semester 2019 (August 2019) annual monitoring event (in which both upper and lower surficial monitoring wells were sampled), monitoring wells 42GW05, 52GW16, 52GW28, 52GW33, 52GW35, 52GW41, 52GW82, 52GW84, N2GW06, N2GW20, N2GW23, N2GW24, N2GW25, N2GW26, N2GW27, N2GW30, N2GW31R, N2GW36, N2GW4C, N2GW50, N2GW58, N2GW59, N2GW61, N2GW69, N2GW74, N2GWRW45A, N4GW01, and N4GW07R revealed SM 6200B compound concentrations at levels exceeding 2L Standards, many of which are chlorinated solvents. Please note, the SM 6200B plume has been modified to only represent boundaries of petroleum-related, dissolved-phase groundwater contamination (based on the GCL list negotiated between the NCDEQ and MCASCP EAD, see letter dated January 15, 2008). See Tables 2.2A through 2.2B and Figures 2.2A and 2.2B. EPA Method 610 by EPA Method 625 During the First Semester 2018 (February 2018) semi-annual monitoring event (in which only lower surficial monitoring wells were sampled), deep monitoring wells contained no EPA Method 610 contaminant concentrations above 2L Standards. During the Second Semester 2018 (August 2018) monitoring event MCAS Cherry Point FY-19; 219001VOL1.RPT44 CATLIN Engineers and Scientists CATLIN Project No. 219001 February 2020 (in which only upper surficial monitoring wells were sampled), monitoring wells N2GW06, N2GW20, N2GW24, N2GW27, N2GW36, N2GW52, N2GW58, N2GW59, N2GW74, N2GW75, N2GWRW45A, and N4GW01 revealed EPA Method 610 contaminant concentrations above 2L Standards. During the Second Semester 2019 (August 2019) annual monitoring event (in which both upper and lower surficial monitoring wells were sampled), monitoring wells N2GW06, N2GW20, N2GW24, N2GW27, N2GW36, N2GW58, N2GW59, N2GW74, N4GW01 and N4GW07R revealed EPA Method 610 contaminant concentrations above 2L Standards. The ten monitoring/recovery wells found to contain free product are considered non-compliant as well. The EPA Method 610 plume has been modified based on the current sampling event’s free product and analytical results. See Tables 2.3A through 2.3B and Figures 2.3A and 2.3B Please note that site monitoring wells on the sampling schedule were not sampled if they were inaccessible or found to contain free-phase product. 2.6 REMEDIAL SYSTEM AIR MONITORING DATA AND EFFLUENT DISCHARGE DATA Air Contaminant Concentrations: Not Applicable. Effluent Discharge Contaminant Concentrations: See Table 2.4. 2.7 POTENTIAL RECEPTORS Contaminated Water Supply Well(s)?: No Potable Water Supply Well Within 1,000 Feet of Source Area?: No Any Water Supply Well Within 250 Feet of Source Area?: No Surface Water Body Within 500 Feet?: No. Closest is tributary of Sandy Branch, approximately 600 feet north. Past Evidence of Vapors?: No Significant Changes from Previously Reported Data?: None 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. MCAS Cherry Point FY-19; 219001VOL1.RPT44 CATLIN Engineers and Scientists CATLIN Project No. 219001 February 2020 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 MCAS Cherry Point FY-19; 219001VOL1.RPT44 CATLIN Engineers and Scientists CATLIN Project No. 219001 February 2020 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 MCAS Cherry Point FY-19; 219001VOL1.RPT44 CATLIN Engineers and Scientists CATLIN Project No. 219001 February 2020 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 annual groundwater sampling event was planned for August 2019 during which both shallow and deep wells will be sampled. Current: During the Second Semester 2020, 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. The current product recovery efforts will continue for the Second Semester 2019. 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 is fairly stable and not significantly increasing or decreasing. Also, the petroleum-related contaminant concentrations are not approaching any of the established GCLs. In addition, the dissolved-phase contaminant plumes do not appear to be migrating significantly. 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. The next annual groundwater sampling event is schedule for August 2020.
