Project Background and Site Conditions
Background
AGVIQ asked Vironex to provide services to inject an enhanced reductive
dechlorination substrate (ERD) and water at your site (Site #89) at Camp
Lejeune, NC. In general, the vertical treatment zones were between 10 feet
to 25 feet below ground surface (bgs) with the four injection points about
25 feet apart.
Geoloey/Hydroeeoloev
r The site lithology is sandy clay and sand based on well logs.
1W Depth to groundwater is approximately 7-10 feet bgs throughout the base.
Contaminants
The intent of the remedial action is to conduct a pilot study on the use of
ERD to reduce the mass of chlorinated hydrocarbon contaminants present
in the upper portion of the aquifer, thereby reducing groundwater impacts
over the long term.
Reagents
The reagents provided by AGVIQ included ERD (a vegetable oil and
lactate solution)and bromide.

Vironex Mixing and Injection Process
Vironex uses various Direct Push Technology W
(DPT) to advance a specially designed 1.5" and
2.125" O.D. injection tool to the bottom of the r
desired injection zone. Once the target depth has
been achieved, an injection cap is secured to the
top of the tool string.
The solution is prepared to the desired
concentration and is then injected using a
dedicated remediation delivery system that is Custom Designed Injection Rigs
capable of providing specified pressures and flow
rates as well as the desired volumes based on the
subsurface lithology and the manufacturer's
recommendations. Pressure, flow rate, and
concentration can all be adjusted as needed on our
self-contained injection unit.
Vironex targets one to five (1 to 5) foot injection
zones through the customized injection tooling to
provide for vertical distribution of reagents Integrated Pumping and Mixing
throughout the injection zone. Systems
Once the injection tooling has been retracted
through the injection zone at one to five (1 to 5)
foot intervals, it is removed from the borehole.
The borehole is backfilled with appropriate
backfilling material and then patched at the surface r
to match existing surface material.

1.0 INTRODUCTION
This report summarizes the field operations and injection parameters associated with the
installation of a Ferox treatment system at the Marine Corps Air Station, Site 89, Camp Lejeune
North Carolina (The Site). The installation was implemented by ARS Technologies, Inc. (ARS)
on behalf of AGVIQ LLC / CH2M Hill Joint Venture as part of a corrective measure study to
evaluate the effectiveness of Pneumatic Fracturing and Liquid Atomized Injection (PF/LAI)
technologies for the In-Situ emplacement of Zero Valent Iron (ZVI) for the subsurface treatment
of dissolved phase Chlorinated Volatile Organic Compounds (CVOCs).
Target ZVI dosages for the project were as follows: 10,400 pounds of H-200 ZVI powder and
1200 pounds of HC-15 ZVI powder (ranging from 15 to 200 microns) divided over four
temporary injection borings. The target mass per boring was 2600 pounds H-200 and 300 pounds
HC-15. Injections were to be applied from an approximate depth of 12 ft bgs to 25 ft bgs in five
discrete 2.5 foot intervals. Target dosage per interval was 520 pounds H-200 and 60 pounds HC-
15. Where appropriate, higher H-200 dosages were used to compensate for extra ZVI (625
pounds)that was shipped to the site.
Field operations at the Site were performed from November 28th through December 3rd, 2006.
A total of 10,160 pounds of H-200 and 1188 pounds of HC-15 were emplaced within the four
proposed injection borings and two offsets. These two offset points were required to achieve the
target mass of H-200 and HC-15 for ZVI-4.
2.0 SITE BACKGROUND
The Marine Corps Air Station, Camp Lejeune, is an active military facility where the primary
contaminants consist of CVOC's. The water table is located approximately 3 feet below ground
surface (bgs) in various-sized sand layers overlain by a thin surficial layer of sandy clay.
3.0 TECHNOLOGY BACKGROUND
A critical component of ARS' injection process is ensuring that the reactive media is distributed
effectively within the subsurface to facilitate the desired chemical reactions. To accomplish this
distribution, ARS incorporates its gas-based PF/LAI Technologies for the subsurface
emplacement of reactive media barriers.
PF is a patented process in which a gas is injected into the subsurface at pressures that exceed the
combined overburden pressure and cohesive soil strength of the geologic matrix, and at flow
rates that exceed the effective permeability of the undisturbed soil. The result is the propagation
of fractures outward from the injection well to various distances depending upon the geology.
Depending upon the permeability or heterogeneities within the targeted geologic zone, PF may
be integrated as a precursor to LAI of a reactive media.

Soil fracturing mechanisms in coarse-grained soils vary considerable from fine-grained cohesive
soils and consolidated rock formations. In a coarse grained soil, it is theorized
that the formation will not "fracture" in the normal brittle sense but rather be cut or intruded by
the pneumatic injection system. More specifically, under circumstances where geologic
conditions comprise of coarse-grained particles such as sands, distribution is accomplished
through the fluidization effect (Figure I — a and b) resulting in the dilation of interconnected
pore space and the temporary suspension or "fluidization" of the coarse grained particles in
response to the influx of gas. The LAI Technology relies upon this theory and is based on the
fact that it is more effective to inject a low viscosity gas or "aerosols" into the subsurface than it
is to inject an incompressible liquid into the subsurface.

4.0 INJECTION WELL INSTALLATION
Injection well installation was directly integrated with the injection operations. A total of six (6)
temporary injection points (4 proposed and 2 offsets)were required to emplace the targeted mass
of ZVI. Borings were installed with an Auger Rig utilizing 3.5 inch solid flight augers which
were advanced to the maximum target depth at each location. The augers were retracted and 4.25
inch diameter casing was subsequently advanced to the maximum target depth. Once the
injection tooling was lowered to depth, the casing was retracted to a point where the packers
were exposed to the formation. This methodology assured that the target depths could be
reached and prevented borehole collapse before the injection tooling reached the bottom of hole,
as well as to prevent material from caving in on the injection tooling and locking it in place. In
the case of Injection Point ZVI-2 and ZVI-4 Offset 2, 5 inch diameter casing was used.
5.0 INJECTION PROCEDURES AND PARAMETERS
This section summarizes the operational procedures and parameters monitored as part of the
injection process. The parameters discussed below may be used as confirmatory measures to
determine whether reagents were successfully propagated within the targeted treatment intervals.
The specialized equipment used for the injection process consisted of a skid mounted high
pressure-high flow fracture module complete with an injection control manifold and a digital
data logger that are used to monitor various operational parameters. Due to the large quantity of
compressed gas needed for the liquid injections, ARS used pressurized nitrogen as the
fracturing/delivery fluid. A bulk nitrogen "tube" trailer was mobilized to the site for this
operation.
Injection of the ZVI within the target treatment zones was accomplished utilizing a nitrogen gas
stream integrated with a high-pressure, high-flow injection manifold. The reagent slurry was fed
into the gas stream from a proprietary mixing trailer that maintains the reagents in suspension by
continual circulation of the slurry. Once sufficiently mixed, the dual phase slurry/nitrogen blend
was routed through a proprietary injector fitted with a 360' high-flow dispersion nozzle.
Injections were performed in approximately 2.5-foot intervals. Injections were accomplished by
starting at the deepest interval and working upward. When the target dosage for each respective
treatment was emplaced into the formation, the packers were deflated, and the nozzle assembly
was raised to the next injection location.
During the injection process, ARS personnel monitored the quantity of iron slurry injected as
well as the duration of each injection. The quantity of material was recorded after each injection.
For the ZVI slurry injections, each batch was specifically mixed within the holding tank and
subsequently injected, ensuring accurate mass loading rates.
During the injections, pressure influence was measured at wells near the injection points using
calibrated pressure (psi) gauges. Each pressure gauge is outfitted with a drag arm indicator that
records the maximum pressure detected at the monitoring point during the injection. The

analysis of pressure response at various locations around an injection point provides
supplemental evidence of reagent propagation. This data also assists in determining which
directions fractures and the subsequent reagent may have propagated. In addition, the degree of
pressure response can often help determine whether a monitoring point has been directly
influenced (i.e. fractures propagate outward and intersect wells or boreholes), or indirectly
influenced through localized groundwater displacement and/or mounding. Minimal pressure
response in monitoring wells located close to the injection point may indicate that fluidization
and significant gas dispersion is occurring.
Ground surface heave was also monitored to determine gas propogation. The heave monitoring
was conducted using a surveying transit in conjunction with a heave rod, which was placed
adjacent to the injection point. The rod was observed for the maximum amount of upward
motion (surface heave) and the post-injection resting position(residual heave). During the course
of this project, ground surface heave has recorded for most fracture events. Surface heave and
associated groundwater surfacing was visually observed with the naked eye in multiple locations
for the majority of events where gas was applied.
6.0 SUMMARY OF FIELD OPERATIONS
This section summarizes the field operations and provides a discussion of the down-hole
injection parameters specific to each injection boring and discrete interval. Mobilization for the
fieldwork began on November 27th and equipment setup was performed on November 28th,
2006. A total of 5.5 days were required to complete the reagent injections.
The historically heterogeneous nature of the soils at the site required fracturing as a preemptive
measure to facilitate ZVI propagation and distribution within the silty clay and reasonably
competent cemented sand layers within the targeted treatment zones. A fracture event was
initiated at all intervals where it was feasible.
As a result of the high water table in the region, surfacing of groundwater occurred in multiple
locations during injections at each boring. The surfacing of the groundwater, coupled with the
permeable nature of the formation resulted in groundwater surfacing through abandoned borings
and natural surface fissures. These site specific conditions required limited use of gas during ZVI
injections, so a "pulsed" gas approach was utilized to minimize seal loss and control to some
extent groundwater surfacing. It should be noted that, under most circumstances during the
injections, groundwater mounding was observed, not ZVI slurry.
Examination of the Pressure vs. Time Curves generated from the fracture events, revealed the
formation did not fracture. The curves themselves show a "flat-line" shape, where the initiation
and maintenance pressures were essentially the same. (See Graphs 1 through 11) The lack of a
discernable pressure peak is indicative of soil fluidization typically observed in predominantly
unconsolidated sands. It was determined in the field that in some intervals constant gas flow of
over 200 scfrn could be achieved as low as 10 psi, suggesting very receptive zones of high
permeability.

Due to groundwater surfacing and subsequent seal-loss issues, ZVI-4 required two offset
locations, and ZVI-2 required re-drilling with a larger casing to address the designated treatment
zone. The re-advancement of a larger casing served to stabilize the borehole wall providing a
fresh surface for the packers to seal against.
Operational parameters collected during each injection event included the discrete injection
interval, initiation and operational pressures recorded on the control module and wellhead,
pressure influence at surrounding monitoring wells and visual field observations. Tables 1
through 4 summarize the quantities of ZVI that were emplaced within each interval specific to
each borehole location. Slurry injection rates varied from approximately 10 to 30 gallons per
minute.
6.1.1 Injection Point ZVI-1
On November 30th 2006, a total of 7 injections were successfully applied across the five target
treatment intervals from a depth of 12.5 ft to 25 ft bgs. A total of 2,750 lbs of H-200 and 300 lbs
of HC-15 were injected at an averaged injection pressure of 25 psi. As a result of groundwater
mounding, surfacing of groundwater occurred during the third interval and jeopardized the
packer seal against the formation. For the final two intervals, the dosages were halved and two
injection events were used to complete each interval. Injection pressures, H-200 and HC-15
mass, slurry volumes, pressure influence and surface heave data were collected during the
injections and are presented in Table 1.
A total of seven wells were monitored for pressure influence, which are listed in Table 1.
During the injections, direct influence was observed 15 feet away at MW-50 in the form of
groundwater mounding indicating induced connectivity through propagation of fluidized
migration pathways resulting from the injections. Pressure influence at this monitoring point
peaked at 10 PSI. When vented, groundwater and pressurized gas were expelled from the
monitoring packer installed in MW-50. This venting continued throughout the course of
injections at ZVI-1. During the second interval slurry injection, the well cap of MW-03IW,
located 60 feet away, blew off. This well was then monitored for the duration of injections at this
point and registered positive pressure.
6.1.2 Injection Point ZVI-2
On December 2nd 2006, a total of 6 injections were successfully applied across five targeted
treatment intervals from a depth of 12.25 to 26.25 ft bgs. A total of 2,170 lbs of H-200 and 300
lbs of HC-15 were injected at an averaged injection pressure of 30 PSI. Injection pressures, H-
200 and HC-15 mass, slurry volumes, pressure influence and surface heave data were collected
during the injections and are presented in Table 2.

At this location, the deepest interval placed the injection nozzle in what was perceived to be a
fairly competent cemented sand layer. In order to mitigate the possibility of damage to MW-02
(approximately 7 feet away) from the high flow rates associated with a pneumatic fracture event,
the injection pump was used to initiate flow into the formation. At 250 PSI, water began to flow
freely into the formation and the injection pressure dropped to 50 PSI. Once this occurred, gas
was applied at 70 PSI and 200 SUM to confirm flow and propagate any hydraulically induced
fractures.
During the fracture event of the second interval, groundwater mounding led to surfacing at
numerous locations around the injection point, and compromised the injection point seal. The
surfacing of groundwater became severe during the injection at the fourth interval. The boring
was re-drilled using a five inch diameter casing in order to address the fourth and fifth intervals.
The advancement of a larger casing served to stabilize the borehole wall and create a new surface
against which the packers could seal.
A total of six wells were monitored for pressure influence, which are listed in Table 2. Direct
pressure influence was recorded at MW-02 during the injections at the upper three intervals. The
well expelled groundwater and gas during the injections. The lack of connection with well MW-
02 within the lowest two injection intervals was encouraging due to the fact that well MW-02 has
a shallow well screen (14 ft bgs). The lack of influence at MW-02 during the deepest 2 intervals
suggests that the gas and slurry were being distributed horizontally within the targeted deeper
intervals.
6.1.3 Injection Point ZVI-3
On December Ist 2006, a total of 5 injections were successfully applied across the 5 targeted
treatment intervals within Injection Point ZVI-3, from a depth of 12.50 — 25 ft bgs. A total of
2,640 lbs of H-200 and 288 lbs of HC-15 were injected at an averaged injection pressure of 30
psi. Injection pressures, H-200 and HC-15 mass, slurry volumes, pressure influence and surface
heave data were collected during the injections and are presented in Table 3.
A total of seven wells were monitored for pressure influence during injection within ZVI-3.
MW-02 (approximately 17 feet away) showed continuous pressure influence for all injection
events. Significant surfacing of groundwater and gas occurred in multiple locations around ZVI-
3, at distances of up to 30 feet away. This may have had a lessening effect on the impact of gas
on the monitoring wells. ZVI slurry began to surface out of cracks in the asphalt around MW-52
(approximately 25 feet away) during the injection event at the third interval, suggesting
significant propagation of the slurry within the subsurface. The surfacing of ZVI was a likely
result of gas and slurry intersecting the grout column of MW-52.

6.1.4 Injection Point ZVI-4
On November 29th 2006, a total of 2 injections were successfully applied, completing the deepest
two of the five targeted intervals from 21.25 — 26.25 ft bgs. Loss of seal during gas injection at
the third interval necessitated an offset boring, ZVI-4 Offset. On December 1st 2006, a total of 2
injections were successfully applied, completing the third interval, 18.75 —21.25 ft bgs at ZVI-4
Offset. Loss of seal at the injection point, as well as surfacing of groundwater and ZVI slurry out
of previous boring ZVI-4, during gas injection of the fourth interval necessitated a second offset
boring, ZVI-4 Offset 2. On December 3rd 2006, a total of 2 injections were successfully applied
at ZVI-4 Offset 2, completing the upper two intervals from 12.25 — 17.25 ft bgs. A total of 2,600
pounds of H-200 and 300 pounds HC-15 were injected over the course of the three borings, at an
averaged injection pressure of 25 psi. Injection pressures, H-200 and HC-15 mass, slurry
volumes, pressure influence and surface heave data were collected during the injections and are
presented in Table 4. A higher dosage ratio was used at ZVI-4 Offset 2 due to the likelihood of
seal loss and to compensate for the extra ZVI shipped to the site.
A total of seven wells were monitored for pressure influence. During injections at the ZVI-4,
MW-50 (approximately 35 feet away) showed significant influence even when vented.
Groundwater and gas were continuously emitted from the vented monitoring well throughout the
course of injections. MW-02IW (approximately 15 feet away) also showed continuous pressure
influence. These pressure influence data suggest good propagation of gas and slurry in that
direction. When fracturing was initiated and gas was applied to start the third interval at ZVI-4
Offset 2 the grout seal around MW02-IW was blown out. Injections at the two offset points
generated pressure influence at MW-02 (approximately 20 feet away).
7.0 CONCLUSIONS BASED ON FIELD INJECTION PARAMETERS
The installation of a Feroxsm treatment system was successfully completed at Site 89. The
mechanics and overall process of the injection were applicable to the site conditions. Due to the
heterogeneous nature of the treatment zone, on-the-field adjustment of the injection parameters
such as flow,pressure and methodology was crucial to the effectiveness of the delivery.
Subsurface injections at this site presented unique challenges in the form of geologic
heterogeneities coupled with a very shallow water table and high permeability sands within the
majority of the target treatment zones. Consequently, these conditions were not conducive
towards full-atomization (continuous nitrogen gas flow) during ZVI injections. In an effort to
minimize groundwater surfacing and mitigate monitoring well blow-outs, the injections were
completed using pulses of gas as opposed to continuous flow. The technique of"pulsing" limits
the over-stressing of the formation with large volumes of gas, thereby minimizing the extent of
groundwater mounding and subsequent surfacing.
The target dosages specified in the Scope of Work were achieved for each boring and
corresponding intervals resulting in the emplacement of 10,160 pounds of H-200 and 1,188

pounds of HC-15 ZVI within the targeted treatment intervals from an approximate depth of 12 ft
bgs to 25 ft bgs. Delivery of the ZVI was accomplished through the utilization of 6 temporary
injection borings which included two offset locations.
Pressure response measurements collected at surrounding monitoring points during the Feroxsm
injections revealed significant radial pressure influence. More specifically, pressure influence
was consistently observed at monitoring points located up to 60 ft from the injection wells.
The Pressure vs. Time curves identified soil fluidization as the primary ZVI transport mechanism
rather than fracture propagation. This conclusion was based on the general flat-lined pressure
response observed during injections. The absence of a discernable initial peak provides evidence
that fracture initiation and propagation did not occur. A flat lined pressure response is indicative
of pore space dilation. This is type of response is typically observed in sandy formations and
represents the point where equilibrium is established between the injected gas and the dilated
pore volume of the formation.

1.0 INTRODUCTION
This report summarizes the field operations and presents the injection data parameters
associated with a Pneumatic Fracturing (PP) application implemented by ARS
Technologies on behalf of AGVIQ LLC/CH2M FULL Joint Venture at the Marine Corps
Air Station, Site 89 located at Camp Lejeune, North Carolina (The Site). The scope of
services entailed the Pneumatic Fracturing of four (4) boreholes from a depth of 12.5 —
25.0 feet bgs to increase soil permeability and augment the remedial performance of an
air sparge horizontal well system currently operating at the site.
2.0 TECHNOLOGY BACKGROUND
PF can best be described as a process whereby a gas is injected into the subsurface at
pressures exceeding the natural in-situ pressures present in the soil/rock interface (Le.
overburden pressure, cohesive stresses, etc.) and at flow volumes exceeding the natural
permeability of the subsurface. The result of this action is the propagation of fractures
outward from the injection point. Unconsolidated materials such as silts and clays
typically exhibit fracture propagation distances of 20 - 40 feet. In most geologic
formations the propagation is relatively uniform around the injection well. The
traditional PF technology creates fractures in cohesive soils such as clay and also in rocks
(shale, sandstone, etc.). Such geologic formations exhibit "self propping" behavior,
which means that the asperities present on the fracture surface are appreciable, and fluid
flow is maintained through the openings.
3.0 FRACTURE BOREHOLE INSTALLATION
Fracture well installation was directly integrated with ARS' injection operations_ A total
of four (4) temporary injection points installed with a conventional Auger Rig utilizing a
5 inch solid drill casing which was advanced to the maximum target depth at each
location. Once the injection tooling was lowered to depth, the casing was retracted to a
point where the packers were exposed to the formation. This methodology assured that
the target depths could be reached and prevented borehole collapse before the injection
tooling reached the bottom of hole, as well as to prevent material from caving in on the
injection tooling and locking it in place.
4.0 INJECTION PROCEDURES AND PARAMETERS
This section summarizes the operational procedures and parameters monitored as part of
the pneumatic fracturing process. The parameters discussed below may be used as
confirmatory measures to determine whether fractures were initiated and successfully
propagated within the targeted treatment intervals.
ARS Technologies, Inc.

The specialized equipment used for the injection process consists of a skid mounted high
pressure-High flow fracture module complete with an injection control manifold and a
digital data logger that are used to monitor various operational parameters. Injection
pressures are regulated with a high-pressure, high-flow injection manifold The manifold
system provides precise control of injection pressures combined with sufficient flows,
which enabled the creation and/or enhancement of fractures within the subsurface. The
duration of the PF injections typically ranged between 10 to 15 seconds.
Fracture Initiation and Maintenance Pressures: During each PF injection, pressures in
the discrete fracture interval were recorded by a pressure transducer located in-line within
the conduit leading to the injection nozzle. These pressures are recorded by a data
logging system located on the injection module and accessed using a lap top computer.
By comparing the magnitude and shape of the pressure-history curve to previously
collected curves in similar geology, an assessment can be made on whether fracture
initiation and propagation occurred. This information allows the evaluation of two
critical measurements; the fracture initiation pressure and the fracture maintenance
pressure. A typical PF event can be subdivided into three distinct stages consisting of:
-Breakdown of formation
-Fracture Initiation
-Fracture Maintenance
These independent stages are illustrated in Figure I. It should be noted that the shape of
the pressure-time history curve dep-.nds on a number of factors including insitu stress
fields and geologic characteristics of the medium being fractured.
The following section describes each stage as it relates to the PF mechanism as illustrated
in Figure 1. During the first stage idenlifed as "breakdown", the pressure rapidly builds
up as gas is injected into the discrete sealed interval of the borehole. "Phis stage is
I dentified as curve segment A-B. The formation of these initial elevated pressures result
from the fact that the formation is not yet fractured and still has low permeability. This
stage is relatively short and typically last 1-2 seconds. Once the pressure exceeds the
insitu stress conditions and media strength prevailing within the sealed pressurized
interval, the formation yields and fracture initiation instantaneously occurs_ The pressure
at this instant is identified as the initiation pressure identified as Stage B in Figure 1.
Following the instantaneous fracture initiation stage, the pressure decreases rapidly in the
sealed interval and eventually stabilizes at a pressure plateau as the injection continues.
During this time period, high volumes of gas rush out of the pressurized interval and
fractures propagate radially into the formation. This accounts for the rapid decline in the
borehole pressure as represented by curve segment B-C. The pressure plateau C-D
represents a period of the fracture maintenance and dilation, which is nearly constant for
the remainder of the injection period. This pressure indicates that an equilibrium state
has been attained for that particular injection flow rate. During this period, the flow rate
into the fractured formation exactly equals the leak-off into the formation from the

fracture surfaces and tips As the injection pressure is terminated, the maintenance
pressure declines rapidly from D-E.

Pressure Influence at Arljacent Monitoring Wells: During the fracturing events,
pressure gauges were placed at select monitoring wells to monitor pressure influence.
Each pressure gauge was fitted with a maximum drag-arm indicator, which enables the
user to monitor the maximum pressure influence at that location during each event.
During the injections, pressure influence is measured at wells near the injection points
using calibrated pressure (psi) gauges. Each pressure gauge is outfitted with a drag arm
indicator that records the maximum pressure detected at the monitoring point during the
injection. This data also assists in determining which directions fractures may have
propagated. In addition, the degree of pressure response can often help determine
whether a monitoring point has been directly influenced (i.e. fractures propagate outward
and intersect wells or boreholes, or indirectly influenced through localized groundwater
displacement and/or mounding. Minimal pressure response in monitoring wells located
close to the injection point may indicate that fluidization and significant gas dispersion is
occurring.

.Surface Heave: Ground surface heave is used as one of the primary methods to detect
fracture initiation and propagation. Since soil is a deformable medium, the observed
surface heave represents the lower limit of fracture aperture and radius. Ground surface
heave measurements were recorded during each fracturing event using a surveying level
in conjunction with a heave rod. A heave rod was placed at a predeternuned radial
distance from the fracture well. During each injection event, the rod was observed for
the maximum amount of upward motion (surface heave) and residual or permanent
heave.
5.0 FIELD IMPLEMENTATION SUMMARY
This section summarizes the field operations and provides a discussion of the down-hole
injection parameters specific to each injection boring and discrete interval_ Field
operations at the Site were performed from April 4 through April 6, 2007. Operational
parameters collected during each injection event included the discrete injection interval,
initiation and operational pressures recorded on the control module and wellhead,
pressure influence at surrounding monitoring wells, surface heave and visual field
observations. Table I presents the data collected within each interval specific to each
borehole location.
PF injections were accomplished by starting at the deepest interval and working upward.
Following the completion of a discrete fracturing interval, the packers were deflated, and
the nozzle assembly was raised to the next injection location.
5.1 Pneumatic Fracturing Boring PF-1
Injection operations at boring PF-1 were performed on April 4, 2007 The fracturing
injection intervals at borehole PF-1 were as follows:
1) 22.25 - 25.5 ft bgs
2) 19.0 - 22.5 ft bgs
3) 15.75 19.0 ft bgs
4) 12.5 15.75 ft bgs
Fracture boring PF-1 was located to the north of Building TC864. The PF injections at
this location resulted in the short-circuiting of gas around the down-hole injection
tooling. More notably and in all cases, short-circuiting occurred towards the end of the
injection event. It is important to note that this occurrence did not render the fracturing
ineffective since, at a minimum, each discrete interval was fractured for a sufficient time
(>10 seconds) and at flowrates (averaging = 2000 SCFM) to adequately initiate and
propagate fractures.
ARS Technologies, Inc.
210

Data parameters recorded for PF-1 are presented in Table 1 of this report. The fracture
initiation and maintenance pressures ranged from 80 to 300 psi and 50 to 200 psi,
respectively. More notably, fracturing initiation pressures were highest within the
deepest intervals suggesting the presence of a more competent low-permeable material.
Pressure/Flow vs. Time curves generated from Fracture Events 1, 2, 3 and 4 are
presented in the attached Figures The curves pertaining to events 1, 2 and 3 illustrate
prominent fracture curves with distinct peak pressures confirming fracture initiation and
propagation within the respective interval The smoothed rounding appearance for
Fracture Event 4 is indicative of dilation of fractures and/or leak-off into more permeable
Portions or seams of the isolated interval through the duration of the fracture event.
Surface heave measurements recorded during the PF injections are presented in Table 1.
One location adjacent to the injection well was monitored for heave during the fracturing
injections. Heave measurements during the fracturing phase of the operations ranged
between 0.1 and 0.3 inches.
During the PF injections pressure influence was observed at wells MW-43 and MW-4313
which were located approximately 40 feet west of boring PF-1. A detailed summary of
pressure influence at surrounding points during injections at PF-1 is provided in Table 1.
5.2 Pneumatic Fracturing Boring PF-2
Injection operations at boring PF-2 were performed on April 5, 2006. The fracturing
intervals at borehole PF-2 were as follows
1) 22.25 — 25.5 11 bgs
2) 19.0 — 22.5 11 bgs
3) 15.75 — 19.0 ft bgs
4) 12.5 - 15.75 ft bgs
Fracture boring PF-2 was located to the south of building TC864. Data parameters
recorded for PF-2 are presented in Table 1 of this report. The fracture initiation and
maintenance pressures ranged from 85 to 400 psi and 70 — 110 psi, respectively. More
notably, fracturing initiation pressures were highest within the deepest intervals
suggesting the presence of a more competent low-permeable material.
Pressure vs. Time curves generated from Events 1, 2 and 3 reveal three prominent
fracture curves with distinct pressures peaks indicating fracture initiation and
propagation. The smoothed mounding appearance of the curves likely resulted from
dilation of previously formed fractures and/or gas leak-off into more permeable portions
or seams within the isolated interval during the early stages of the fracture initiation
process.
ARS Technologies, Inc.
211

Surface heave measurements recorded during the PF-2 injections are presented in Table
1. One location was monitored for heave during the fracturing injections as identified in
Table 1. The monitoring point was located adjacent to the injection well (approximately
feet). Heave measurements during fracturing ranged between 0.1 and 0.3 inches.
During the injections at PF-2, pressure influence was observed at wells MW-48A and
MW-4813 in the form of positive pressure when the valve to the well was opened. A
detailed summary of pressure influence at surrounding points during PF injections at PF-
2 is provided in Table 1.
5.3 Pneumatic Fracturing Boring PF-3
Injection operations at boring PF-3 were performed on April 6, 2006. The fracturing
intervals at borehole PF-3 were as follows:
1) 22.25 — 25.5 ft bgs
2) 19.0 — 22.5 ft bgs
3) 15.75 - 19.Oftbgs
4) 12.5 — 15.75 ft bgs
Fracture boring PF-3 represented the furthest south injection location. Data parameters
recorded for PF-3 are presented in Table 1 of this report. The rTacture initiation and
maintenance pressures ranged from 145 to 340 psi and 100 — 225 psi, respectively.
More notably, fracturing initiation pressures were highest within the deepest intervals
suggesting the presence of a more competent low-permeable material.
Pressure/Flow vs. Time curves generated from Events 1 and 2 reveal prominent fracture
curves with distinct initiation pressures indicating fracture initiation and propagation.
The smoothed mounding appearance of the curves representing Events 3 and 4, likely
resulted from gas leak-off into more permeable portions or seams within the isolated
interval during the early stages of the fracture initiation process.
Surface heave measurements recorded during the PF-3 injections are presented in Table
1. One location was monitored for heave during the fracturing injections as identified in
Table 1. The monitoring point was located adjacent to the injection well (approximately
3 feet) Heave measurements during fracturing ranged between 0.1 and 0.5 inches
During the injections at PF-3, pressure influence was observed at wells MW-49A and
MW-49B in the form of registered pressure influence on the gauge and positive pressure
when the valve to the well was opened. Direct pressure influence was also observed at
boring PF-4 during the PF-3 injections. A detailed summary of pressure influence at
surrounding points during PF injections at PF-3 is provided in Table 1.

5.4 Pneumatic Fracturing Boring PF-4
Injection operations at boring PF-4 were performed on April 6, 2006. The fracturing
intervals at borehole PF-4 were as follows:
1) 22.25 25.5 ft bgs
2) 19.0 — 22.5 ft bgs
3) 15.75 — 19.0 ft bgs
4) 12.5 - 15.75 ft bgs
Fracture boring PF-4 was located between borings PF-2 and PF-3. Data parameters
recorded for PF-4 are presented in Table 1 of this report. The fracture initiation and
maintenance pressures ranged from 140 to 320 psi and 80 — 190 psi, respectively. More
notably, fracturing initiation pressures were highest within the deepest intervals
suggesting the presence of a more competent low-permeable material.
Pressure vs. Time curves generated from Events 2, 3 and 4 reveal prominent fracture
curves with distinct initiation pressures indicating fracture initiation and propagation_
The smoothed mounding appearance of the curves illustrated in Event 1, likely resulted
from gas leak-off into more permeable portions or seams within the isolated interval
during the early stages of the fracture initiation process.
Surface heave measurements recorded during the PF-4 injections are presented in Table
1. One location was monitored for heave during the fracturing injections as identified in
Table 1. The monitoring point was located adjacent to the injection well (approximately
3 feet). Heave measurements during fracturing ranged between 0.1 and 0.4 inches.
Influence was not observed at any of the monitored wells. Lack of pressure influence at
monitoring well cluster MW-49A and 49B which were greater than 40 feet away.
6.0 CONCLUSION
A pneumatic fracturing application was recently completed at Marine Corps Air Station,
Site 89 Camp Lejeune North Carolina. A total of four (4) boreholes were fractured from
a depth of 12.5 to 25.5 feet bgs. Data parameters collected as part of the PF process, such
as surface heave measurements, pressure response measurements in surrounding
monitoring wells and boreholes, and the pressure-history curves, indicates that fractures
were successfully initiated and propagated within the targeted areas. The pressure-
history curves indicate that the soils fractured numerous times during the field effort.
Initial pressure peaks indicate that fractures were created with at pressures ranging from
80 to 400 psig. Fracturing initiation pressures were highest within the deepest intervals

suggesting the presence of a more competent low-permeable material. During a few
applications, the pressure curves indicate a "mounded" pattern that is indicative pore
space dilation of existing fractures and/or more permeable soils. During PF operations,
pressure responses were observed in monitoring wells and in one instance (PF-3) at
distances up to 40 feet from the injection borings indicating successful propagation of
fractures and subsequent permeability enhancements within the targeted treatment
intervals.

TECHNICAL MEMORANDUM CH2MHILL
Proposed Monitoring Approach for Potential Vapor
Intrusion Pathways, Site 89
To: Camp Lejeune Partnering Team
FROM CH2M HILL
DATE: October 4, 2007
This Technical Memorandum provides an update to a previous memorandum (June 8,2007)
which presented a preliminary evaluation of vapor soil data soil collected during an air
sparging treatability study and the proposed approach for monitoring potential vapor
intrusion pathways in buildings at Site 89 at Marine Corps Base (MCB) Camp Lejeune,
North Carolina. The preliminary evaluation of vapor intrusion was based on data from
four rounds of sampling that were collected during the treatability study;this memorandum
evaluates the soil gas vapor data collected during the entire study (i.e., six rounds).
Presented in this memorandum is an overview of the site setting, an evaluation of analytical
data from the completed air sparging treatability study,proposed monitoring approaches,
and a recommended monitoring approach.
Background
Air sparging (AS) was one of four treatability studies conducted at MCB Camp Lejeune Site
89 to evaluate the performance and effectiveness for remediation of trichloroethene (TCE),
tetrachloroethene (PCE),and associated dissolved chlorinated solvent contamination. The
treatability studies were not intended to be a final remedy for the site but were intended to
evaluate the performance and design criteria of four remedial technologies. Air sparging
was tested in an area with a relatively small,elliptical plume,conducive to treatment
through a well that has been installed using Horizontal Directional Drilling (HDD)
methods. Areas of very groundwater high contamination(in the percent levels) were
avoided during installation of the horizontal well. The HDD sparge well was constructed
with a 240-foot long screen, and was positioned at approximately 40 feet below ground
surface near building TC864. The total lineal distance of the well was approximately 600
feet. The air sparge system was activated on December 8,2006 and operated continuously
for approximately six months.The compressor"up time" was approximately 89%.
Operation of the system was concluded in July 2007. Groundwater monitoring was
performed during the treatability study including a baseline sampling event,followed by
six monthly sampling events. Due to the presence of buildings around the sparge area,three
soil vapor monitoring wells (SVMW) were installed and monitored for volatile organic
compound (VOCs) in conjunction with the groundwater monitoring. The analytical results
from the soil vapor monitoring wells are presented in Table 1. The location of the
treatability study area and the SVMWs are shown in Figure 1. Two SVMWs (IR89-SV01 and
IR89-SV02) are located adjacent to building TC860. One SVMW (IR-SV03) is located
adjacent to building TC864.

PROPOSED NUNUORMAPPROPCH FOR PMENTIALVAPORNML)SIONPATHWAYS,SrTE 89
Purpose and Objectives
An approach was developed for evaluating potential vapor intrusion pathways in the
nearby buildings prior to full-scale implementation of AS at Site 89. The purpose for
evaluating potential vapor intrusion pathways is to be able to identify when potential
pathways might create indoor air impacts,so that mitigation measures can be implemented
in a timely manner. Since air sparging involves injection of air to remove or biodegrade
subsurface contaminants,there is the possibility of creating pressure fields that might result
in some degree of transport of volatile contaminants.
A preliminary evaluation of the soil gas sampling data was conducted in June 2007 to
evaluate the potential for vapor intrusion pathways in buildings located near the area where
AS is being conducted. These preliminary results were compared with the generic default
screening levels in soil gas presented in U.S. Environmental Protection Agency's (EPA) draft
vapor intrusion guidance (EPA,2002). Eight of 21 VOCs detected in soil gas were detected
at concentrations higher than the generic screening levels. TCE and PCE were detected at
concentrations greater than 50 times the generic screening levels. In accordance with EPA's
vapor intrusion guidance, site-specific screening levels were calculated for TCE and PCE
using the Johnson and Ettinger model. The assumptions associated with these screening
levels are described in Table 2. As seen in Table 1,concentrations of TCE in some samples
approached,but did not exceed,the site-specific screening level. Concentrations of PCE
were lower than the site-specific screening level.
Based on the preliminary evaluation, different approaches were developed for monitoring
potential vapor intrusion pathways near the buildings:
Alternative 1: Continue to monitor soil gas in these wells,and use the data in the site-
specific Johnson and Ettinger model to evaluate potential exposures. During full-scale AS
implementation,periodically monitor soil gas from these wells to determine if a build up in
soil gas concentrations is occurring. Soil gas sampling and analysis would be conducted
using Summa canisters with the sampling analyzed using EPA Method TO-15. Other
monitoring methods, such as detector tubes (Drager tubes) or photoionization detectors
(PID) probably would not provide usable data for modeling. However,a PID might be
usable to monitor trends in total VOC concentration,which can be used to increase or
reduce the frequency as needed of sampling using the Summa canisters.
Alternative 2: Conduct a building survey to determine if that building is resistant to vapor
intrusion. That involves surveying the building for cracks in the floor (or sumps, or drains),
that could be conduits for soil gas,and determining if the building is depressurized -is it
pulling air from the subsurface indoors-by making measurements with a micromanometer.
If the building is pressurized and vapor-resistant,that result combined with the soil gas
sampling data may be useful in documenting that no further vapor intrusion evaluation is
needed. This approach would address the potential vapor intrusion pathway without the
need for intrusive indoor air and subslab sampling.
Alternative 3: Engage the base industrial hygienists,and addressing the potential exposure
pathway as an occupational exposure situation. As appropriate,Navy industrial hygienists
perform indoor air sampling using industrial hygiene methods,and comparing the results
with appropriate occupational exposure limits. If the levels in air do not represent a
workplace exposure,then no further action would be needed (beyond any soil gas

monitoring we would do normally as part of the full-scale implementation of the AS
system). Soil gas monitoring could continue periodically, as described above.
Alternative 4: Perform a vapor intrusion investigation,with subslab and indoor air
samples, as described in EPA's draft 2002 guidance.
Updated Data Evaluation
Soil vapor samples were collected during a baseline sampling event,followed by six
monthly sampling events (Table 1). The final soil vapor samples associated with the study
were collected on July 11 and July 12,2007. Twenty-two VOCs were detected in soil gas.
Soil vapor monitoring wells 89-SV01 and 89-SV02 show an increasing trend in
concentrations in soil gas through out the study,though concentrations in 89-SV02 decrease
in the last sampling event. In general, soil vapor monitoring well 89-SV03 shows a spike in
contaminant concentrations one month after system start-up,followed by a decrease in
concentrations;PCE and TCE concentrations increase in the July sampling event.
Ten VOCs were detected at concentrations greater than the generic screening criteria in at
least one soil vapor sample collected during the course of the treatability study: PCE;TCE;
cis-1,2-Dichloroethene;vinyl chloride; 1,1,2,2-tetrachloroethane (PCA);methylene chloride;
chloroform;benzene;1,2,4-trimethylbenzene; and 1,3,5-trimethylbenzene. PCA,PCE, and
TCE were detected at concentrations greater than 50 times the generic screening levels;
therefore, site-specific screening criteria were calculated for these compounds.
Concentrations of these three VOCs were lower than the site-specific screening level.
Recommendations for Further Investigation
Although the soil vapor concentrations collected during the treatability study did not
exceed site-specific screening criteria, the sampling data indicate an increasing trend in soil
gas concentrations. At this time,it is not apparent that the air sparging treatability study
has created potential vapor intrusion pathway. However, the soil vapor monitoring data
collected suggests that longer-term air sparging could produce higher concentrations in soil
vapor than observed during the treatability study. This could create an increased potential
for vapor intrusion pathways in buildings near the air sparge well. In addition, areas of Site
89 have higher groundwater concentrations than those in the treatability study area. Air
sparging in these areas with higher concentrations in groundwater also suggest there is the
potential for higher soil vapor concentrations to be observed,if air sparging is selected as
the final remediation technology for Site 89.
All though a combination of the four proposed alternatives may need to be implemented,
the initial recommended approaches for vapor intrusion evaluation are Alternative 1 (soil
gas sampling and modeling) and Alternative 2 (building surveys). Routine soil vapor
monitoring (using a combination of real-time monitoring and soil vapor sampling) would
be conducted in the vicinity of all buildings in the area in which air sparging is being
conducted. Installation of additional soil vapor monitoring wells may be needed to monitor
soil vapor concentrations in the vicinity of other buildings that may be near the sparge line.
If the sampling data and modeling indicate an increasing trend in soil gas concentrations,
and an increasing potential for vapor intrusion pathways in a building,then a subsequent
step would be to implement Alternative 2,which would involve performing a building

survey. The results from that survey could be used to refine the modeling, or could be used
to identify mitigation measures that would reduce potential exposures through vapor
intrusion. The need for further investigation (industrial hygiene survey, or interior vapor
intrusion investigation) would be based on the results from these modeling and survey
activities.
