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.

CATLIN Project No. 217001 August 2017
2.4.4 Free Product Removed from Site This Period: 2 gallons
2.4.5 Significant Changes from Previously Reported Data: None. Free product
continues to be present in well 72GW01.

2.5 Dissolved-Phase Plume

2.5.1 Plume Concentrations: See Tables 2.2A through 2.3B.
2.5.2 Plume Size and Location: See Figure 2.2 and Figure 2.3.
2.5.3 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)
Lower surficial monitoring wells were last sampled during the First Semester 2016
event. During that event, concentrations of 1,1-Dichloroethane (72GW25 and
72GW29) and Trichloroethene (72GW27) were revealed exceeding their
respective 2L Standards.

Lower surficial monitoring wells were again sampled during the First Semester
2017 monitoring event. Monitoring wells 72GW25 and 72GW29 revealed
concentrations of 1,1-Dichloroethane above the 2L Standard. 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 2.2C and Figure 2.2A.

EPA Method 610 by EPA Method 625
During the previous (Second Semester 2016) monitoring event, only the upper
surficial monitoring wells were sampled. Lower surficial monitoring wells were last
sampled during the First Semester 2016 event. During that event, no EPA Method
610 compounds were detected above their respective 2L Standards.

During the First Semester 2017 monitoring event (only lower surficial wells were
sampled) no EPA Method 610 compounds were detected above their respective
2L Standards. See Tables 2.3A and 2.3B and Figure 2.3A.

Please note that site monitoring wells scheduled for this sampling event were not
sampled if they were inaccessible or found to contain free-phase product.

2.9 Observations and Comments

2.9.1 Historical: The Air Station O&M contractor, SDC Group, Inc. has been and
continues to operate the AS/SVE system, as well as utilize petroleum absorbent
socks to collect free-phase product if it appears and conduct AFVR events as
necessary. 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 was began in early
2014.

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. Also, an AFVR event was conducted on April 16, 2014 at well 72GW01
which yielded 1.8 gallons of free-phase product recovery.

Gauging data from January through April 2015 indicated free-phase product was
consistently detected in well 72GW01. Therefore, an additional AFVR event was
conducted at well 72GW01 on April 8, 2015 which yielded approximately seven
gallons of free-phase product. Free-phase product was again detected in this well
during the May and June 2015 gauging events.

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
MCAS Cherry Point FY-17; 217001VOL1.RPT39 CATLIN Engineers and Scientists
CATLIN Project No. 217001 August 2017
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 the all of 2016 (January through December 2016). The system
operation appeared to be positively influencing dissolved-phase contaminant
concentrations based on their generally declining trend.

2.9.2 Current: The AS system operated for approximately 11 hours per day, seven
days per week during the First Semester 2017 (January through June 2017). The
current system operation will be continued in the Second Semester 2017 as it
appears to be positively influencing dissolved-phase contaminant concentrations
based on their generally declining trend. The data from system operation is
continually evaluated and modifications to system operation are implemented each
semester to maximize remediation results.

Gauging data over the past year (July 2016 through June 2017) indicated free-
phase product was periodically detected in well 72GW01. A project to delineate
the extent of free-phase product around this well began in March 2017, this project
is ongoing as a third round of temporary well installation is planned in August
2017. At the completion of this project an updated Conceptual Site Model will be
prepared which will be utilized to develop a revised remediation plan for the
remaining free-phase product. Ultimately, a more aggressive remediation
approach (such as excavation) will be implemented to address the residual free-
phase product at the subject site. In the interim, passive recovery and/or
additional AFVR events may be conducted to recovery free-phase product.

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 February 2016 monitoring event, deep monitoring well 74GW24 and
shallow monitoring well 74GW23 were sampled. Deep monitoring well 74GW24
revealed no contaminant concentrations above the 2L Standards. Shallow
monitoring well 74GW23 revealed contaminant concentrations exceeding the 2L
Standard for Benzene, Isopropylbenzene, Toluene and Total Xylenes.

During the August 2016 monitoring event (in which both shallow and deep wells
were sampled), EPA Method 602 contaminant concentrations exceeding their
respective 2L Standards were revealed in these wells as follows: 1,1-
Dichloroethane (74GW15 and 74GW16), Benzene (72GW34, 72GW52A,
74GW15, 74GW16, 74GW23 and 74GW29), Isopropylbenzene (74GW23),
Naphthalene (74GW16), Toluene (74GW23), Total Xylenes (74GW23),
Tricholoroethene (72GW52A and 74GW29) and Vinyl Chloride (74GW16).

During the current (February 2017) monitoring event, in which only shallow
monitoring well 74GW23 was sampled, contaminant concentrations exceeding
the 2L Standards for Benzene, Isopropylbenzene, Toluene and Total Xylenes
were revealed.

Standard Method 6200B plume boundaries have been modified based on the
current monitoring event’s analytical data. See Tables 7.2A through 7.2C and
Figures 7.2A and 7.2B.

EPA Method 610 by EPA Method 625
During the February 2016 monitoring event, deep monitoring well 74GW24 and
shallow monitoring well 74GW23 were sampled and neither well revealed
contaminant concentrations above the 2L Standards.

During the August 2016 monitoring event (in which both shallow and deep wells
were sampled), contaminant concentrations exceeding the 2L Standards for
Benzo(b)fluoranthene, Benzo(a)anthracene, 2-Methylnaphthalene and
Naphthalene were revealed in monitoring well 74GW16.

During the current (February 2017) monitoring event, in which only shallow
monitoring well 74GW23 was sampled, no EPA Method 610 contaminant
concentrations were revealed above their respective 2L Standards.

7.6 Remedial System Air Monitoring Data and Effluent Discharge Data

7.6.1 Air Contaminant Concentrations: Not Applicable
7.6.2 Effluent Discharge Contaminant Concentrations: Not Applicable

7.7 Potential Receptors

7.7.1 Contaminated Water Supply Well(s)?: No
7.7.2 Potable Water Supply Well Within 1,000 Feet of Source Area?: No
7.7.3 Any Water Supply Well Within 250 Feet of Source Area?: No
7.7.4 Surface Water Body Within 500 Feet?: No
7.7.5 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.
7.7.6 Significant Changes from Previously Reported Data?: None.

7.8 Remediation

7.8.1 Status: AS/SVE Operating
7.8.2 Type: AS/SVE, and natural attenuation
7.8.3 Progress: Ongoing;
7.8.4 Construction Contractor: J.A. Jones
7.8.5 Operating Contractor: SDC Group, Inc./GES

7.9 Observations and Comments

7.9.1 Historical: The Air Station O&M contractor, SDC Group, Inc. has been and
continues to operate 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.

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
MCAS Cherry Point FY-17; 217001VOL1.RPT39 CATLIN Engineers and Scientists
CATLIN Project No. 217001 August 2017
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.

Current: The AS system operated for approximately 11 hours per day, seven
days per week during the First Semester 2017 (January through June 2017). The
current system operation will be continued in the Second Semester 2017. The
data from system operation is continually evaluated and modifications to system
operation are implemented each semester to maximize remediation results.

The Benzene concentration in monitoring well 74GW23 are the main regulatory
driver at the subject site. The Benzene concentration in this well over the past
approximately two years is as follows:

 August 2015 = 10,900 ug/L
MCAS Cherry Point FY-17; 217001VOL1.RPT39 CATLIN Engineers and Scientists
CATLIN Project No. 217001 August 2017
 February 2016 = 4,590 ug/L
 August 2016 = 9,310 ug/L
 February 2017 = 11,200 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 and dissolved oxygen levels in the vicinity of this well in the First
Semester 2017 have not significantly increased.

System operations are recommended that will attempt to increase air flow around
this well which may help to reduce the Benzene concentration. If these
recommendations can not be implemented or if once implemented, do not appear
to influence the Benzene concentrations then alternative remediation efforts in the
vicinity of this well will be evaluated and implemented. An annual groundwater
sampling event of select on-site wells (including 74GW23) is planned for August
2017.

Notes: 1. 2L GWQS = North Carolina Groundwater Quality Standard 15A NCAC 2L .0202
2. GCL = Gross Contamination Levels for groundwater as defined in "Guidelines for Assessment and
Corrective Action for UST Releases" July 15, 2008 Version, Change 3 Effective December 1, 2013
3. All units are in ug/L (Micrograms per Liter)
4. BQL = Below Quantitation Limits
5. NA = Not Analyzed
6. A zero in the 2L GWQS column indicates the 2L Standard is equal to the laboratory detection limit
7. A zero in the GCL column indicates a GCL has not been established
8. Shaded concentrations indicate exceedance of the 2L GWQS
