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.

7.5 DISSOLVED-PHASE PLUME
Plume Concentrations: See Tables 7.2A through 7.3B.
Plume Size and Location: See Figures 7.2 through 7.3.
Significant Changes from Previously Reported Data:
SM 6200B
(The EPA Method 602 analytical list was utilized until the First Semester 2013 sampling event,
where it was replaced with the full SM 6200B analytical list)
During the August 2017 monitoring event (in which both shallow and deep wells
were sampled), SM 6200B contaminant concentrations exceeding their
respective 2L Standards were revealed in these wells as follows: 1,1-
Dichloroethane (74GW16), Benzene (72GW52A, 72GW62, 74GW16, 74GW23),
Isopropylbenzene (74GW23), Naphthalene (74GW16), Toluene (74GW23), Total
Xylenes (74GW23), Tricholoroethene (72GW52A and 74GW29) and Vinyl
Chloride (74GW16).
During the previous (February 2018) monitoring event, in which only shallow
monitoring well 74GW23 was sampled, contaminant concentrations of Benzene,
Isopropylbenzene, Toluene and Total Xylenes were again revealed above their
respective 2L Standards.
During the current (August 2018) monitoring event (in which both shallow and
deep wells were sampled), SM 6200B contaminant concentrations exceeding
their respective 2L Standards were revealed in these wells as follows: 1,1-
Dichloroethane (74GW16), Benzene (72GW52A, 74GW16 and 74GW23),
Isopropylbenzene (74GW23), Naphthalene (74GW16), Tricholoroethene
(72GW52A and 74GW29) and Vinyl Chloride (74GW16).
Shallow monitoring well 74GW23 was also sampled in November 2018 and
revealed SM 6200B contaminant concentrations of Benzene, Isopropylbenzene
and Total Xylenes exceeding the 2L Standards. Standard Method 6200B plume
boundaries have been modified based on the current monitoring event’s
analytical data. See Tables 7.2A, 7.2B and Figure 7.2.
EPA Method 610 by EPA Method 625
During the August 2017 monitoring event (in which both shallow and deep wells
were sampled), EPA Method 610 contaminant concentrations of 2-
Methylnaphthalene and Naphthalene above their respective 2L Standards were
revealed in monitoring well 74GW16.
During the previous (February 2018) monitoring event, in which only shallow
monitoring well 74GW23 was sampled, no EPA Method 610 contaminant
concentrations were revealed above their respective 2L Standards.
During the current (August 2018) monitoring event, in which both shallow and
deep wells were sampled, monitoring well 74GW16 again revealed contaminant
MCAS Cherry Point FY-18; 218001VOL1.RPT42 CATLIN Engineers and Scientists
CATLIN Project No. 218001 February 2019
concentrations of 2-Methylnaphthalene and Naphthalene above their respective
2L Standards.
Shallow monitoring well 74GW23 was also sampled in November 2018 and no
EPA Method 610 contaminant concentrations were revealed above their
respective 2L Standards. EPA Method 610 plume boundaries have been
modified based on the current monitoring event’s analytical data. See Tables
7.3A, 7.3B and Figure 7.3.
Please note that site monitoring wells were not sampled if they were inaccessible
or found to contain free-phase product.
7.6 REMEDIAL SYSTEM AIR MONITORING DATA AND EFFLUENT DISCHARGE
DATA
Air Contaminant Concentrations: See Table 7.4.
Effluent Discharge Contaminant Concentrations: Not Applicable.
7.7 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
Past Evidence of Vapors?: No. Two air quality monitoring reports previously
developed by J.A. Jones revealed no vapor issues at either Building 130 or
Building 140. However, vapors were discovered in Building 131 during a
previous Air Sparge testing. Since this discovery, modifications have been made
to the AS and SVE system to alleviate the problem.
Significant Changes from Previously Reported Data?: None.
7.8 REMEDIATION
Status: AS/SVE system was shut down in the beginning of January 2019 to
facilitate site closure.
Type: AS/SVE, and natural attenuation
Progress: Ongoing
Construction Contractor: J.A. Jones
Operating Contractor: SDC Group, Inc./GES
7.9 OBSERVATIONS AND COMMENTS
Historical: The Air Station O&M contractor, SDC Group, Inc. has historically
operated the AS/SVE system. The AS/SVE system operated until early
December 2013 at which time the air sparge system was shutdown due to water
accumulating in the SVE lines which renders the SVE system ineffective to
remove vapors from the air sparging. An investigation into the source of water
entering the SVE lines began in early 2014.
MCAS Cherry Point FY-18; 218001VOL1.RPT42 CATLIN Engineers and Scientists
CATLIN Project No. 218001 February 2019
Additional system improvements such as reconfigured control logic and air flow
regulators have been implemented to optimize system operation. In addition,
replacement of the ball valves and installation of sight glasses at the AS/SVE
wells has been implemented to aid in the reduction of water accumulating in the
SVE lines.
Since air sparge operations have not been consistent over an extended time
period, CATLIN continues to evaluate total system operations and has been
monitoring the high benzene concentrations in well 74GW23. Groundwater
samples from well 74GW23 have indicated Benzene concentrations between
approximately 10,000 ug/L to 20,000 ug/L from 2009 to 2013.
The groundwater sample from well 74GW23 in August 2014 indicated Benzene
at a concentration of 6,820 ug/L which was a decrease in the historical
concentrations, but the concentration is still above the GCL (5,000 ug/L) for this
compound. Also, due to the high levels of contamination in this sample and the
sample from well 74GW16 the laboratory had to dilute these samples and
analyze them a second time. Unfortunately the re-analysis was conducted
beyond the “hold” time for the SM 6200B method and therefore the reported
results for these two wells are suspect. To address this situation, these shallow
wells were resampled during the semi-annual sampling event in March 2015.
The analytical results from March 2015 for the groundwater sample from well
74GW23 revealed Benzene at a concentration of 8,620 ug/L which is a decrease
in the historical concentrations of 10,000 to 20,000 ug/L, but the concentration
was still above the GCL (5,000 ug/L) for this compound.
The investigation of the source of water entering the SVE lines was completed in
the First Semester 2015 but the results were inconclusive. Pressure testing of
the system was conducted and the results of the pressure testing of the system
indicated there are leaks in the piping system(s); however, these areas are
inaccessible and can not be easily repaired. Therefore, attempting to fix the
leaks in the system was determined to be cost prohibited; rather, a detailed plan
was developed to restart the AS system in a staggered pattern and at specific
pressures. The restarting of the AS/SVE system commenced on July 1, 2015.
Between July and Mid-October 2015 continual adjustments were implemented in
operating the AS/SVE. Over this time period the AS/SVE system operated
periodically. By Mid-October 2015 the proper adjustments were made and from
Mid-October through December 2015 the AS system operated effectively at the
subject site. As of December 2015, the AS system was operating for
approximately 11 hours per day, seven days per week.
The AS system operated for approximately 11 hours per day, seven days per
week during all of 2016 (January through December 2016), except for routine
down time for any operation and maintenance activities. Also, the AS system
operated for approximately 11 hours per day, seven days per week during the
First Semester 2017 (January through June 2017). During the Second Semester
2017 (July through December 2017) the AS system operated for approximately
12 hours per day, seven days per week.

week during the First Semester 2018 (January through June 2018), except for
routine down time for any operation and maintenance activities.
Current: The AS system operated for approximately 12 hours per day, seven
days per week during the Second Semester 2018 (July through December 2018)
except for routine down time for any operation and maintenance activities and
weather shutdowns (i.e. Hurricane Florence in September 2018). The system
operation appears to be positively influencing dissolved-phase contaminant
concentrations based on their declining trend. The Benzene concentration in
monitoring well 74GW23 is the main regulatory driver at the subject site. The
Benzene concentration in this well over the past three and a half years is as
follows:
August 2015 = 10,900 ug/L
February 2016 = 4,590 ug/L
August 2016 = 9,310 ug/L
February 2017 = 11,200 ug/L
August 2017 = 3,700 ug/L
February 2018 = 4,900 ug/L
August 2018 = 137 ug/L
November 2018 = 229 ug/L
As documented above, the Benzene concentration in August 2015 was 10,900
ug/L and in February 2016 it dropped to 4,590 ug/L which was a significant
reduction and below the GCL and appeared to be attributable to the increased
air flow from the sustained air sparging operations. However, well 74GW23 was
sampled again in August 2016 and the Benzene concentration was 9,310 ug/L
which was an increase from February 2016. During the Second Semester 2016
decreased air flow from the remediation system was noted around well 74GW23.
The February 2017 results again showed an increase in Benzene concentrations
to 11,200 ug/L Therefore, AS system adjustments were implemented in an
attempt to increase the influence in the vicinity of this monitoring well. Benzene
results in this well from the August 2017 sampling event revealed a significant
decrease to 3,700 ug/L. The February 2018 results showed a slight increase in
Benzene concentrations to 4,900 ug/L which was still below the GCL for
Benzene of 5,000 ug/L. Therefore, AS system adjustments were again
implemented in an attempt to increase the influence in the vicinity of this
monitoring well. The adjustments stated above appear to have been successful
as the August 2018 and November 2018 sampling results revealed a significant
decrease in the Benzene concentration in well 74GW23.
Based on the significant reduction in the Benzene concentration in well 74GW23,
it was decided to shut down the AS/SVE system in early January 2019. Site
monitoring wells will be sampled in February 2019 to monitor for any rebound
after system shutdown. The February 2019 sampling results will be evaluated to
determine the next steps forward to move the site towards NFA status.
