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.

Average Linear Groundwater Flow Velocity: Lower Surficial Aquifer = 2.2549
feet/day
Groundwater Flow Direction: Lower Surficial Aquifer = West. See Figure 6.1.
Range of Measured Water Table Elevations: Ranges from 11.30 feet in
monitoring well 59GW40 to 18.89 feet in monitoring well 59GW39. See Tables
6.1A and 6.1B.
Significant Changes from Previously Reported Data: The lower surficial
groundwater flow direction has changed from Northwest to West.
6.4 FREE PRODUCT PLUME
Free Product Present?: No.
Free Product Thickness Measured: During the First Semester (February
2018) monitoring event, 34 wells were gauged and no wells contained
measurable free-phase product. See Tables 6.1A and 6.1B.
Plume Size and Location: See Figure 6.1
Free Product Removed from Site This Period: None.
Significant Changes from Previously Reported Data: None. Measureable
free product was last detected in well 59GW26 in July and October 2017 during
“weekly” gauging events.

6.5 DISSOLVED-PHASE PLUME
Plume Concentrations: See Tables 6.2A through 6.4B.
Plume Size and Location: See Figures 6.2A through 6.4B.
Significant Changes from Previously Reported Data:
EPA Method 602 by SM 6200B
During the previous (August 2017) monitoring event, only upper surficial
monitoring wells were sampled. Lower surficial monitoring wells were last
sampled during the February 2017 monitoring event and during that event, no
EPA Method 602 contaminant concentrations were detected above 2L
Standards. During the current (February 2018) monitoring event, in which only
lower surficial monitoring wells were sampled, no EPA Method 602 contaminant
concentrations were detected above 2L Standards. See Tables 6.2A through
6.2B and Figures 6.2A and 6.2B.
EPA Method 610 by EPA Method 625
During the previous (August 2017) monitoring event, only upper surficial
monitoring wells were sampled. Lower surficial monitoring wells were last
sampled during the February 2017 monitoring event and during that event, EPA
Method 610 contaminant concentrations were detected exceeding the 2L
Standards in deep monitoring wells 59GW13, 59GW33 and 59GW41.
During the current (February 2018) monitoring event, in which only lower surficial
monitoring wells were sampled, EPA Method 610 contaminant concentrations
were again detected exceeding the 2L Standards in deep 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
During the previous (August 2017) monitoring event, only upper surficial
monitoring wells were sampled. Lower surficial monitoring wells were last
sampled during the February 2017 monitoring event and during that event, deep
monitoring wells 59GW13 and 59GW33 revealed MADEP VPH/EPH
contaminant concentrations exceeding the 2L Standards.
During the current (February 2018) monitoring event, in which only lower surficial
monitoring wells were sampled, MADEP VPH/EPH contaminant concentrations
exceeding the 2L Standards were revealed in monitoring wells 59GW13,
59GW33 and 59GW41.
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.

6.8 REMEDIATION
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. On March 9, 2016 the SVE system was restarted and well
59GW26 was converted to an SVE well.
Type: SVE; free-phase product removal via two solar skimmer pumps. AFVR.
Progress: System operating
Construction Contractor: Shaw
Operating Contractor: SDC Group, Inc./GES
6.9 OBSERVATIONS AND COMMENTS
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
MCAS Cherry Point FY-18; 218001VOL1.RPT41 CATLIN Engineers and Scientists
CATLIN Project No. 218001 August 2018
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.
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 continued to
persist in well 59GW26 alternative remedial approaches were being evaluated.
Also, groundwater sampling had not been conducted at the subject site since
August/November 2013; therefore a groundwater sampling event was conducted
in September 2015. Analytical results from the September 2015 groundwater
sampling event revealed an overall declining trend in contaminant
concentrations.
Monthly gauging data from January and February 2016 revealed that free-phase
product continued to persist in well 59GW26. Therefore, it was decided 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. These modifications were implemented and the SVE system was
restarted on March 9, 2016. Also, the semi-annual sampling of the lower
surficial monitoring wells was conducted in February 2016. The groundwater
sampling results revealed a continuing overall declining trend in contaminant
concentrations. Monthly gauging activities for the Second Semester 2016
revealed that free-phase product was detected in well 59GW26 from September
through November 2016. The shallow wells at the subject site were sampled in
August 2016 and results revealed a continuing overall declining trend in
contaminant concentrations.
Monthly gauging activities for the First Semester 2017 revealed that free-phase
product was not detected in any on-site wells. The deep wells at the subject site
were sampled in February 2017 and results revealed a continuing overall
declining trend in the dissolved-phase contaminant concentrations. Monthly
MCAS Cherry Point FY-18; 218001VOL1.RPT41 CATLIN Engineers and Scientists
CATLIN Project No. 218001 August 2018
gauging activities for the Second Semester 2017 revealed that free-phase
product was detected in 59GW26 in July and October 2017 during “weekly”
gauging events. The shallow wells at the subject site were sampled in August
2017 and results revealed that contaminant concentrations are relatively low and
no levels are approaching any of the established GCLs. The shallow dissolved-
phase plume shifted slightly towards the northwest as compared to the August
2016 plume location. However, there are numerous shallow wells to the
northwest of the current plume that could be sampled to ensure that any plume
migration is adequately tracked.
Current: Monthly and weekly gauging activities for the Second Semester 2017
revealed that free-phase product was not detected in any on-site wells. The
deep wells at the subject site were sampled in February 2018 and results
revealed a continuing overall declining trend in the deep, dissolved-phase
contaminant concentrations.
Free-phase product has not been detected in well 59GW26 since October 2017
at the subject site. Select on-site monitoring wells will continue to be gauged on
a monthly basis. Due to the lack of any measurable free-phase for over eight
months it is recommended that the SVE system be shut down. If measureable,
free-phase product reappears at the subject site then passive recovery of free-
phase product will commence. Also, it should be noted that the buildings at the
subject site are planned for demolition within the next few years. Therefore, an
excavation of any gross contamination and residual free-phase product may be
easily accessible during this upcoming demolition project. In the interim, the
SVE system will continue to operate. Also, the shallow wells are scheduled to be
sampled in August 2018 to continue to track the shallow, dissolved-phase
contaminant trends.
