FOREWORD

The U.S. Environmental Protection Agency (EPA) is charged by Congress with protecting the nation's
natural resources. Under the mandate of national environmental laws, the EPA strives to formulate and
implement actions leading to a compatible balance between human activities and the ability of natural
systems to support and nurture life. To meet this mandate, the EPA's Office of Research and
Development (ORD) provides data and scientific support that can be used to solve environmental
problems, build the scientific knowledge base needed to manage ecological resources wisely, understand
how pollutants affect public health, and prevent or reduce environmental risks.

The National Exposure Research Laboratory (NERL) is the Agency's center for investigation of technical
and management approaches for identifying and quantifying exposures to human health and the
environment. Goals of the laboratory's research program are to (1) develop and evaluate methods and
technologies for characterizing and monitoring air, soil, and water; (2) support regulatory and policy
decisions; and (3) provide the scientific support needed to ensure effective implementation of
environmental regulations and strategies.

This report presents the activities, results, findings, and recommendations of sampling conducted from
January through February, 2008 at Naval Air Station (NAS) Lemoore, Installation Restoration Program
(IRP) Site 14 to investigate the vertical distribution of volatile organic compounds (VOCs) in soil gas
from groundwater to the surface and subslab environments. This report was co-authored by Mr. James
Elliot and Dr. Greg Swanson of Tetra Tech. The authors acknowledge the contribution of Dr. Brian
Schumacher and Mr. John Zimmerman, the EPA task order project officer and co-project officer, in
conducting key parts of the field work, providing guidance throughout the project, and providing
insightful comments on the draft report. The author also acknowledge the tremendous support of Mr.
Frank Nielson of the NAS Lemoore environmental staff, who facilitated access to IRP Site 14 to conduct
the testing and provided logistical support and ongoing assistance with operations during the field
sampling activities.

EXECUTIVE SUMMARY

Tetra Tech EM, Inc. (Tetra Tech EMI) was contracted by the U.S. Environmental Protection Agency
(EPA) to assess the vertical and horizontal distribution of volatile organic compounds in the subsurface,
from groundwater to the surface/subslab environment, and to develop a database of paired macro-purge
and micro-purge soil gas sample measurements. In addition, sampling was conducted to evaluate the
performance of a variety of soil gas probe construction materials (tubing types) and to test passive
diffusion samplers (PDSs).

The field study was conducted at Installation Restoration Program (IRP) Site 14 on Naval Air Station
(NAS) Lemoore, California. IRP Site 14 is located in the operations area of NAS Lemoore and consists
of maintenance buildings, hangars, and aircraft parking areas. Chlorinated volatile organic compounds
(VOCs) are the primary contaminants that have been found in soil, soil gas, and groundwater at IRP
Site 14 near the Building 180 hangar, the adjacent aircraft parking area, and near Buildings 170 where
this investigation was conducted. The plume of chlorinated VOCs at IRP Site 14 is composed primarily
of trichloroethene (TCE) and 1,1-dichloroethene (DCE), with minor amounts of 1,2-DCE, 1,1-
dichloroethane (DCA), 1,2-DCA, and tetrachloroethene (PCE). Fuel residuals are also commingled with
the chlorinated solvents. Two discernable VOC plumes are present at IRP Site 14: one emanating from
the Building 180 area, and one located south of Building 170.

Two transects of six macro-purge (standard 1/8 inch tubing size) sampling locations were established at
the site. The locations are in two lines (transects) oriented approximately east-west, with a southern
(primary) transect and a northern (secondary) transect. In each transect, the two western-most locations
are located on an approximately 6-inch thick concrete pad, and the remaining four locations in each
transect are east of the slab, in an unpaved area. At each location, soil vapor probes were installed at 2, 4,
7, and 10 feet below ground surface (bgs). At the four locations on the concrete slab, subslab soil gas
probes were installed immediately beneath the concrete. Collocated micro-purge (0.01 inch tubing size)
sampling locations were installed along the southern (primary) transect. PDS wells were installed at
depths of 2, 4, 7, and 10 feet bgs at four locations in the southern transect and at two locations adjacent to
a former jet engine test cell. At two locations in the southern transect, clusters of macro-purge probes
constructed with different tubing types (stainless steel, copper, polyetheretherketone [PEEK], Teflon,
Nylaflow, and polyethylene) were installed at approximately 6 feet bgs.

The sampling probes were installed in pilot holes advanced to groundwater at depths between 10.7 and
11.5 feet bgs. Grab groundwater samples were collected at seven of the locations. Soil samples were
collected from the pilot holes at the probe installation depths (i.e., 2, 4, 7, and 10 feet bgs) at each of the
locations. Soils encountered in the pilot holes consisted primarily of silty sands, clayey sands, and clays.

Each macro-purge and micro-purge probe was sampled at least twice over the course of one week and
analyzed on-site in a mobile laboratory. Collocated micro-purge and macro-purge probes were sampled
concurrently. PDSs were inserted in the PDS wells and allowed to equilibrate for a minimum of 30 days
before being retrieved and submitted for off-site analysis.

Statistical analyses of the paired micro-purge and macro-purge soil gas samples indicate there is a
correlation between the results obtained from the two sampling methodologies; however, the range of
relative percent differences (RPDs) for the macro-purge samples was 50 percent, which is largely within
analytical error, whereas the range of RPDs for the micro-purge samples was 260 percent, suggesting
there are some as yet undetermined issues with this sampling method that are limiting its reproducibility.

The results of analysis of samples obtained from collocated probes constructed with different tubing types
indicate that for most materials, the observed variability in measured concentrations is within analytical

-------
error. Polyethylene tubing consistently yielded VOC concentrations than the other tubing types except
for copper. Copper tubing VOC concentrations were significantly lower than the other tubing types and
their concentrations were inconsistent with one sample being a non-detect and the other having 170 (ig/m3
ofTCE.

After converting the PDS sample results to gas equivalent concentrations using Henry's Law, it was
observed that the TCE and PCE concentration results for the PDSs were generally higher than in the
collocated macro-purge probes. Additional data is needed to more completely assess the performance of
these samplers.

The results of the investigation into the distribution of soil gas VOCs near a slab indicate that, as
expected, VOC concentrations in soil gas decrease with increasing vertical separation from the
groundwater source and with increasing horizontal distance away from the edge of the slab. These
findings are consistent with physical principles of subsurface vapor distribution from a groundwater
source and the impact of a slab as a physical barrier. However, the decline in soil gas VOC
concentrations moving horizontally away from the edge of the slab was more rapid than expected.
Limited groundwater data show a corresponding large decrease in VOC concentrations moving away
from the slab. These observations indicate that the presence of the slab may have a significant and abrupt
impact on VOC concentrations in soil gas and the upper-most groundwater, and have important
implications for sample location selection in vapor intrusion studies.

1.0 INTRODUCTION

Soil vapor data are widely used in site investigation and remediation projects to delineate volatile organic
compound (VOC) vapor plumes, as a screening tool to refine soil and groundwater sampling efforts, to
track the progress of soil remediation, and to assess the vapor intrusion pathway. Vapor intrusion is of
particular concern, as it can be one of the main driving forces behind remediation at VOC sites. A critical
issue in assessing the vapor intrusion pathway is the distribution and migration of VOCs from the
subsurface source to the near surface environment.

It is commonly held that VOCs in a groundwater plume will migrate from groundwater through the
vadose zone and either disperse to the atmosphere if the surface is uncovered, or accumulate beneath a
cover (e.g., a building foundation), and potentially migrate into the indoor air of overlying structures (i.e.
vapor intrusion). Numerical models have been developed to describe the migration of VOCs in the
subsurface environment and to assess the effects of a building foundation or slab (Abreu and Johnson
2005). However, these models incorporate a variety of simplifying assumptions that have not been tested
with field data. Overall, few data are available to document the behavior and distribution of VOC vapors
through the soil column from groundwater to the surface/subslab environment.

Variation in sampling methods, field conditions, and analytical methods may result in variability in soil
vapor measurements. This variability can be seen in differences in soil vapor data collected from the
same location over time or collected from several adjacent locations at the same time. These sources of
variation are essentially "noise" in the data, making it difficult to reach a clear understanding of the
migration of VOCs in soils. A critical element in obtaining usable soil vapor data is the collection of
representative samples. A variety of sample collection techniques are commonly used in the industry, but
little data exist to evaluate the relative merits of the different methods.

There were two primary objectives for this investigation. The first objective was to measure the
distribution of VOCs from the ground water source through the soil to the surface. This distributional
information will be used to help improve our understanding of the mechanisms of vapor migration and
intrusion. The second objective was to develop a robust data set of paired sample results with which to
compare the innovative "micro-purge" sampling technique to the more common "macro-purge"
technique. In the context of this investigation, "macro-purge" refers to probes constructed with standard
tubing size (typically 1/8 inch) whereas "micro-purge" refers to probes constructed with a much smaller
tubing size (0.01 inch). There were also two secondary objectives of this investigation: 1) install, retrieve,
and analyze six sets of an aqueous-based, passive diffusion sampler (PDS) to evaluate the performance of
this new sampling device, and 2) evaluate the effects of different tubing materials of construction on soil
gas measurements.

2.0 SITE BACKGROUND AND PROBE LAYOUT

The field sampling and analysis portion of this project was conducted at IRP Site 14, located on Naval Air
Station (NAS) Lemoore. NAS Lemoore is located in the California Central Valley, approximately 40
miles south of Fresno and 180 miles north of Los Angeles (Figure 2-1).

2.1 IRP SITE 14 SETTING AND BACKGROUND

IRP Site 14 is located in the operations area of NAS Lemoore and consists of maintenance buildings,
hangars, and aircraft parking areas (Figure 2-1). Chlorinated VOCs are the primary contaminants that
have been found in soil, soil gas, and groundwater at IRP Site 14 near the Building 180 hangar, the
adjacent aircraft parking area, and near Buildings 188 and 170. The plume of chlorinated VOCs at IRP
Site 14 is composed primarily of TCE and 1,1-dichloroethene (DCE), with minor amounts of 1,2-DCE,
1,1-dichloroethane (DCA), 1,2-DCA, and tetrachloroethene (PCE). Fuel residuals are also commingled
with the chlorinated solvents; specific VOCs associated with the fuel residuals include trace amounts of
benzene, toluene, ethylbenzene, and xylenes. Other VOCs detected at IRP Site 14 include chloroform
and trichlorotrifluroethane (Freon-113). Two discernable VOC plumes are present at IRP Site 14: one
emanating from the Building 180 area, and one located south of Building 170 (Figure 2-1).

There are several suspected source areas including industrial wastewater lines (IWLs), storm drains, a
manhole, a wash rack, and six former underground storage tanks (USTs). There are also possible spills or
releases to unpaved areas or aircraft parking areas as a result of various practices associated with aircraft
maintenance. However, all IWLs have been repaired or replaced, and all USTs at IRP Site 14 have been
removed.

2.1.1 Geology and Hydrogeology

2.1.1.1 Regional Geologic Setting

NAS Lemoore is located in the San Joaquin Valley, the southern half of California's Central Valley, a
400-mile-long structural basin that borders the Sierra Nevada Mountain Range. The Central Valley is
underlain by a large fault block that tilts down toward the west as the basement rock rose to the east to
form the Sierra Nevada.

The valley has continuously subsided throughout the Pleistocene and Holocene periods. Subsidence
steepened the gradients of rivers that emerge from the Sierra Nevada, promoting the development of
alluvial fan deposits and their subsequent preservation. The fans themselves consist largely of coarse-
grained channel deposits, as finer-grained sediments are discharged by floodwaters that spill out onto the
plain beyond the toe of the fan. A similar process was active on the slopes of the Coast Ranges that
borders the valley to the west.

NAS Lemoore is located immediately west of the trough of the valley. The trough is the lowest and most
level portion of the valley. The ground surface elevation at NAS Lemoore is approximately 230 feet
above mean sea level. Lakes and playas have occupied the trough repeatedly throughout Quaternary
time, leaving behind lacustrine deposits. Lacustrine deposits at NAS Lemoore primarily consist of clay.
The three most extensive lacustrine clays have all been mapped beneath NAS Lemoore; they are referred
to as A Clay, C Clay, and E Clay. The A Clay underlies NAS Lemoore at a depth of approximately 50
feet below ground surface (bgs).

NAS Lemoore is also located near the outer edge of the Kings River alluvial fan. As a result, alluvial
deposits interfmger with lacustrine clays beneath NAS Lemoore. Alluvial deposits are typically olive
brown to olive gray in color and contain sporadic cemented horizons. In contrast to lacustrine deposits,
alluvium is heterogeneous and contains stringers and lens-shaped sand channel deposits that grade
laterally to silty floodplain deposits.

Sediments at IRP Site 14 have the characteristics of both alluvial and lacustrine environments, indicating
pulses of alluvial deposition into a closed, possibly ephemeral lacustrine environment. Lacustrine
environments generally dominate in periods of cooler, wetter climates, such as during periods of
glaciation, the last of which occurred about the time the A Clay was deposited.

2.7.7.2 IRP Site 14 Geology andHydrogeology

Geologic deposits beneath IRP Site 14 consist of an alluvial aquifer composed of sand, silty sand, and
sandy silt interfingered with less permeable deposits of clayey silt and silty clay. The alluvial assemblage
is interrupted by clay interbeds of lacustrine origin at various intervals.

Several groundwater bodies are present beneath IRP Site 14. The shallow uppermost groundwater body
is designated as the A zone aquifer and has the A Clay defining its lower boundary. Depth to A zone
groundwater ranges from 10 to 14 feet bgs. The predominant site-wide groundwater flow in the A zone
aquifer is to the northeast, with a gradient on the order of 0.004 feet per foot (Figure 2-2).

The A-Clay appears to be laterally continuous across the site between depths of 45 and 50 feet (~35 feet
below the groundwater table and the deepest soil vapor probes). Several cores through the A-Clay have
been obtained for the IRP investigation at Site 14, and it is typically logged as a stiff clay with low
plasticity but does not appear reduced (Table 2-1). Geotechnical samples collected in this interval
exhibited a relatively high fraction of organic carbon of between 1 and 2 percent.

Alluvium in the A zone aquifer (approximately 12 to 45 feet bgs) consists largely of granular alluvium
(predominantly sands), especially in the vicinity of the perceived TCE source locations. This granular
alluvium appears to pinch out to the northeast of Site 14. Geotechnical samples collected below the water
table in the 20- to 24- foot bgs range consisted of 70 to 80 percent sand with relatively high effective
porosities (15 to 18 percent). However, these sandy soils are not representative of soils in the Site 14
vadose zone (where the STREAMS vapor probes are installed), which were visually logged as being
predominantly silts and clays (to be verified by the soil samples collected during the equilibration study).
Limited soil physical property data for the vadose zone and A-zone aquifer soils at Site 14 are presented
in Table 2-2.

The other two extensive clay layers beneath the site are the C- and E-Clays. The C-Clay is about 250 feet
bgs and the E-Clay about 680-720 feet bgs (the E-Clay extends throughout the central valley and is also
called the Corcoran Clay - it is the major confining unit in the valley).  All three of the clay layers are
lacustrine.

The  hydrogeology  of the  shallow-upper aquifer beneath IRP Site  14  can be  characterized  as a
heterogeneous alluvial aquifer  with  a relatively flat water table and limited vertical connection  to
underlying aquifer zones. The low-permeability silt and clay units within the aquifer may restrict lateral
movement of contaminants. Downward movement of dissolved contaminants is likely impeded by the
lacustrine clay interbeds, which may constitute locally continuous aquitards.
                                              2-5

-------
The quality of the shallow groundwater is generally poor because of elevated salinity that is likely a result
of irrigation practices in an arid environment. For example, sulfate concentrations above 10,000
milligrams per liter (mg/L) are not uncommon at NAS Lemoore.

2.1.2 Chlorinated Solvent Plume Conditions

Groundwater monitoring results for TCE obtained in January 2007 are presented on Figure 2-3. TCE is
the primary chemical of concern in groundwater. The most significant concentrations (above 1,000
micrograms per liter [|ig/L]) are found adjacent to and east of Building 180 at monitoring wells MW14-
51A, MW14-68A, MW14-250A, and MW14-254B; however, this is a high-traffic area used for aircraft
parking and consists of an excessively thick 18- to 24-inch concrete slab; both of which rendered the area
unsuitable for this study. The area used for this investigation is adjacent to and southeast of Building 170.
TCE was detected in groundwater from monitoring well MW14-70A at a concentration of 230 (ig/L in
January 2007 (Figure 2-3).

2.1.3 Selection of IRP Site 14

Site 14 was selected as a suitable location for this investigation because: (1) it provides a study area over
a well-defined, shallow chlorinated solvent plume, (2) a variety of buildings with slab-on-grade
foundations are present at the site, and (3) Tetra Tech EMI has an established working relationship with
the environmental program staff at NAS Lemoore.

2.2 SOIL VAPOR PROBE TRANSECTS

The following paragraphs summarize the installation of the soil gas probe array at IRP Site 14. Details of
the drilling and probe installation activities are presented in the Sampling Trip Report (Appendix A).

In the Quality Assurance Project Plan (QAPP) (Tetra Tech 2008), a sampling site over and adjacent to the
former Building 173 foundation was proposed; however, during an initial mobilization to install sampling
probes, it was determined that there were insufficient VOC concentrations in the soil vapor in this area
(Appendix A). Therefore, the original transects were abandoned and an alternative site located adjacent
to and east of Building 170 was selected (Figure 2-4).

2.2.1 Macro-Purge Vapor Probes

Two transects of six macro-purge sampling locations were established at the Site. The locations are in
two lines (transects) oriented approximately east-west. Locations in the southern (primary) transect were
designated ST-1 through ST-6. Locations in the northern (secondary) transect were designated NT-1
through NT-6 (Figure 2-4). Locations ST-1 and NT-1 are on the concrete pad adjacent to Building 170.
Locations ST-2 and NT-2 are also on the concrete pad, but at the east edge of it. Locations ST-3 and NT-
3 are off the paving, but immediately adjacent to the concrete pad. Locations ST-4, ST-5, ST-6, NT-4,
NT-5, and NT-6 are in the unpaved area east of the concrete pad (Figure 2-4). At each location, soil
vapor probes were installed at 2, 4, 7, and 10 feet bgs. At locations ST-1, ST-2, NT-1, and NT-2 subslab
soil vapor probes were installed immediately below the concrete pad. In addition, at locations ST-3 and
ST-6, "tubing type clusters" were installed at 6.25 feet bgs.

The tubing-type clusters consist of a bundle of six different tubing types, each with a gas-permeable tip,
installed similarly to the other macro-purge soil gas probes. The tubing types were stainless steel, copper,
polyetheretherketone (PEEK), Teflon, Nylaflow, and polyethylene. All of the tubing types were 1/8-inch
diameter with the exception of the polyethylene, which was only available in 1/4-inch diameter.

The individual probes were identified by the location ID and the depth separated by a dash (e.g., the probe
installed at 4 feet bgs at location ST-1 is designated ST1-4). The subslab probes were identified with the
location ID and "SS" (e.g. ST1-SS). Table 2-1 provides a summary of the probe installation details.

The sampling probes were installed in pilot holes advanced to 10 feet bgs, or to groundwater at depths
between 10.7 and 11.5 feet bgs, using a direct push system. Grab groundwater samples were collected at
the seven locations advanced to groundwater (Table 2-2). Soil samples were collected from the pilot
holes at the probe installation depths (i.e., 2, 4, 7, and 10 feet bgs) at each of the locations (Table 2-3).
Soils encountered in the pilot holes consisted primarily of silty sands, clayey sands, and clays.

Soil vapor probes were constructed as follows. Approximately 3 inches of #3 sand was poured into the
bottom of the pilot holes. A 1-inch long gas-permeable membrane sampling probe, attached to 1/8-inch
diameter Nylaflow tubing, was then lowered through the drill rod to the top of the sand. Additional sand
was then poured around the sampling probe until it extended approximately 2 inches above the membrane
to form an approximately 6-inch long sand pack around the sample point (tubing type clusters were
installed with an approximately 18-inch long sand pack to accommodate the larger purge volume that
would be associated with purging multiple probes in quick succession). Approximately 12 inches of dry
bentonite was then placed on top of the sand pack, followed by hydrated bentonite to approximately 3
inches below the next sampling depth (i.e. 7 feet bgs). This process was repeated to install four nested
soil vapor probes in each pilot hole. At locations on the concrete pad, the subslab vapor probes were
installed in the same way, but in a separate, 1-inch diameter hole that was drilled through the concrete
with an electric hammer drill. The sampling probes were completed at the surface with approximately 18
inches of Nylaflow tubing extending out of the ground and a Swagelok valve was inserted into the end of
the tubing. A schematic diagram of the probe installations is provided in Figure 2-5. The subslab vapor
probes were installed 1 foot or less from the corresponding macro-probes (see Appendix A photograph 14
for visual example).

2.2.2 Micro-Purge Vapor Probes and Passive Diffusion Sampler Wells

Concurrently with the installation of the macro-purge vapor probes, EPA installed micro-purge vapor
probes and passive diffusion sampler (PDS) wells. Micro-purge vapor probes were collocated with the
macro-purge vapor wells in the primary transect (locations ST-1 through ST-6) at depths of 2, 4, 7, and 10
feet bgs. Subslab micro-purge vapor wells were not installed. The micro-purge vapor probes consisted of
0.01-inch inner diameter (ID) stainless steel tubing epoxied into steel point holders. The stainless steel
tubing was threaded through the drill-rods, which were driven to the target sampling depth using the
EPA-operated direct-push rig. Upon reaching the target depth, the drill rod was pulled up approximately
1 inch to expose the drop-off point to the vadose zone. The drill rods were left in place during sampling
in order to seal out ambient air; thus micro-purge probes at multiple depths were installed in separate
boreholes, rather than being nested in a single boring.

Passive diffusion sampler wells consisted of 2-inch diameter PVC blank casing, with an approximately 2-
inch long screened interval at the bottom. The PDS wells were installed in boreholes drilled to the target
sampling depth using the EPA operated direct push rig. PDS wells were installed at locations NT-5 and
NT-6 in the abandoned transect adjacent to the former Building 173 foundation, and locations ST-1, ST-2,
ST-3, and ST-5 in the primary transect. Subslab PDS wells were not installed.

2.3    EXPERIMENTAL DESIGN

The primary objectives of this investigation were to:  1) assess the vertical and horizontal distribution of
VOCs in soils from groundwater to the subslab/near-surface environment, and 2) develop a robust data set
of paired sample results with which to compare the innovative "micro-purge" sampling technique to the
more  common "macro-purge" technique.  There were also two secondary objectives: 1) compare VOC
concentrations detected in "active" soil gas samples (i.e., gas samples obtained by applying a vacuum to a
probe installed at depth) to the concentrations detected in PDSs, and 2) evaluate the effects of different
tubing materials of construction on soil gas measurements.
                                             2-12

-------
To achieve the project objectives, the soil gas sampling transects described in Section 2.2 were installed at
IRP Site 14 on NAS Lemoore, and multiple samples were collected from each probe to develop a three-
dimensional picture of the distribution of VOCs in the vadose zone.  Soil gas samples from collocated
"micro-purge" wells were collected to assess the performance of the "micro-purge" technique in relation
to the standard "macro-purge" technique.  Samples from wells with different tubing types were  collected
to evaluate the impact of tubing type. Finally, PDSs were installed and retrieved to allow comparison of
PDS results to active soil gas measurement results.

3.0 SAMPLING AND ANALYSIS

The following sections describe the sampling and analysis procedures used during the investigation.

3.1 SAMPLE COLLECTION

Active soil gas sample collection consists of two primary components. The first is purging the probe to
remove ambient air and any other gases not representative of subsurface conditions at the target sampling
depth. The second is collection of the soil gas sample into an appropriate container for transfer to the
analytical instrument. Based on the results of five purge tests conducted at a subset of the probes and the
results of the Task Order (TO) 05 investigation (EPA 2007), the volume of gas removed from each probe
prior to sampling (the purge volume) was set at three system volumes (i.e., the volume of the gas
permeable tip plus the tubing). The system volumes for the macro-purge probes are provided in Table 2-
1. Probes were purged at a rate of approximately 200 milliliters per minute (ml/min). The sample
volume from macro-purge probes was set at 20 ml, and the samples were collected in 60-ml, disposable,
polypropylene syringes. Soil gas sampling commenced after a minimum equilibration time of 14 days.

Samples from micro-purge soil gas probes were collected in 2.5-ml glass syringes. System volumes of
the micro-purge probes were 2.025 ml for the 2-foot probes, 2.075 ml for the 4-foot probes, 2.125 ml for
the 7-foot probes, and 2.150 ml for the 10-foot probes. One system volume was purged from each micro-
purge soil gas probe prior to collecting a 2.5-ml sample. Soil gas samples were analyzed on-site in a
mobile laboratory operated by HPMG.

Intact soil cores were retrieved from the transect boreholes in clear, acetate sleeves used as liners in the
drill rod. Soil sample aliquots for VOC analyses were collected from the acetate sleeves and transferred
directly to VOA vials containing methanol and sodium bisulfate preservatives in accordance with EPA
SW-846 Method SW5035 (EPA 1996). Soil samples were submitted to American Environmental Testing
Laboratory, Inc. (AETL), located in Burbank, California for VOC analysis via EPA SW-846 Method
8260B (EPA 1997).

Grab groundwater samples were collected by placing 1-inch diameter slotted PVC screen down the
borehole to a depth approximately 1 foot below the static water level and then allowing the groundwater
level to re-equilibrate. After the water level stabilized, standing water (one volume) was purged from the
screen using a bailer, and then a sample was collected in VOA vials containing hydrochloric acid
preservative. Groundwater samples were submitted to AETL for VOC analysis via EPA SW-846 Method
8260B.

Passive Diffusion Samplers were inserted into the PDS wells in accordance with EPA instructions
(Appendix B) and left in place for a minimum of 30 days to equilibrate. The PDSs were then removed
from the wells and submitted to AETL for VOC analysis via EPA SW-846 Method 8260B.

3.2 MOBILE LABORATORY

Soil gas samples collected for this investigation were analyzed on-site using a mobile laboratory operated
by HPMG. Details of the analytical method, equipment, and detection limit (DL) are provided below.

3.2.1 Analytical Method

Soil gas samples were analyzed by direct injection using EPA SW-846 Method 8021 (EPA 1996).
Method 8021 is a gas chromatography method using a photoionization detector (PID) and an electron
capture detector (ECD). This method is faster, more sensitive, and has a larger linear dynamic operating
3-1

-------
range than gas chromatography/mass spectrometry (GC/MS) methods. The contaminants of concern at
IRP Site 14 (i.e., TCE and PCE) had been previously identified based on IRP investigation data (Section
2.1.2); therefore, the compound identification advantages of GC/MS were not warranted. The target
compound list for this project was limited to TCE and PCE.

Soil gas samples collected during this investigation were sub-sampled using a 1.0-ml syringe and injected
directly into the gas chromatograph injection port. The injection syringes were flushed with the sample
two times prior to injection to ensure the injected aliquot was representative of the field sample and were
flushed several times with clean air between injections or discarded.

The analyses were performed following EPA method 8000 protocols, modified for soil gas.
Modifications from the EPA method consisted of the project-specific analyte list, absence of matrix spike
samples and surrogates, and changes in calibration protocols as discussed in Section 3.3.2.

3.2.2 Equipment

The following equipment was utilized by the mobile laboratory for this project.

• Instrument: SRI 8610 Gas Chromatograph

• Column: 30 meter DB-61, megabore capillary.

• Carrier flow: Nitrogen at 10 ml/min.

• Detectors: PID and BCD.

• Column oven: 80°C isothermal

3.2.3 Detection Limits

The DL for the target compounds was 50 (ig/m3.

3.3 QUALITY ASSURANCE/QUALITY CONTROL

3.3.1 Field Quality Control Protocols

Leak tests were performed on five probes to monitor the integrity of the probe system and surface seals.
Leak tests were conducted at probes ST2-2, ST4-2, ST6-2, NT 1-2, and NT3-2. The 2-foot bgs probes
were selected for leak checks as they are considered the most likely to fail. Leak tests were conducted by
placing a cloth rag in a plastic bag, saturating the rag with 1,1-difluoroethane (DFA), placing the bag over
the surface completion of the probe, and then purging the probe normally and collecting a sample. If
DFA was detected in the sample, then it would have been concluded that the probe was not sealed
properly from the atmosphere. Leak check samples were collected in Tedlar bags and sent back to
HPMG's fixed laboratory for analysis, as the mobile laboratory was not equipped to analyze for DFA.
No DFA was detected in any of the samples associated with the leak checks.

Purge volume tests were conducted to determine the optimum volume of gas to purge from each probe
prior to sample collection. Purge tests were conducted on probes ST1-10, ST2-10, and ST3-10 (Table
3-1). The purge tests consisted of purging one or two system volume and then collecting a sample,
purging another one or two system volumes (for a total of two or three) and collecting a sample, and
purging another two or three system volumes (for a total of five), and collecting a sample. The sample
results were then compared to determine what purge volume yielded the highest measured VOC
concentrations. The results of the purge volume tests did not convincingly indicate that any tested purge

Therefore, the standard three system-volume purge was used for

Field duplicate samples were collected to measure the reproducibility and precision of the total sampling
system. Field duplicate samples were collected at a rate of approximately 11 percent from macro-purge
probes and 14 percent from micro-purge probes. All quantifiable soil gas field duplicate results were
within the QAPP specified criterion of ±40 relative percent difference (RPD). A summary of the
duplicate results for soil gas samples is provided in Table 3-2. One field duplicate soil sample was
analyzed for the set of 16 field samples analyzed (rate of approximately 6 percent). The results were not
detected (ND) for all analytes, therefore an RPD could not be calculated. Field duplicate groundwater
samples were not collected.

3.3.2.2
Instrument Calibration
An initial  3-point calibration curve was performed at  the  start of and used throughout the  project.
Although EPA method 8000 requires the use of five levels for an initial calibration curve; existing soil
gas guidance  from the  California Environmental Protection Agency Department of Toxic Substances
Control (DTSC 2003) only requires three calibration levels. A linearity check of the calibration curve for
each compound was performed by computing a correlation coefficient and an average response factor.

Continuing calibration verification samples were analyzed once a day as specified in the  QAPP (Tetra
Tech 2008).  These standards were prepared from a traceable source at the middle concentration of the
                                               3-4

-------
calibration curve. Acceptable continuing calibration agreement was set at ±20 percent to the average
response factor from the calibration curve.

3.3.2.3 Blanks

Laboratory blanks were analyzed at the start of each field day. A total of five blank samples were run
during the sampling conducted on February 25 through 29, 2008.

3.3.3 Project QAPP Deviations and Additions

During the course of implementing the program, several deviations occurred from the guidelines
discussed in the QAPP (Tetra Tech 2008). Specific deviations are listed below.

• The QAPP stated that the sampling transects would be located on and adjacent to the concrete
slab foundation of former Building 173; however, it was found that the VOC concentrations in
soil gas in this area were insufficient for the purposes of this investigation. Therefore, an
alternative location was selected adjacent to Building 170 (Section 2.2).

• The QAPP stated that soil samples collocated with each soil gas probe would be collected and
analyzed for VOCs. Soil samples were collected as proposed in the QAPP; however, due to the
very low VOC concentrations present in the soils, only a subset of the soil samples collected were
analyzed.

3.3.4 QC Sample Results

All field quality control sample results were compliant with guidelines and QC criteria prescribed in the
QAPP. Twelve duplicate field samples were collected from the macro-purge probes and six were
collected from the micro-purge probes. All of the results were compliant with the QAPP specified RPD
criterion of 40 percent.

All of the laboratory QC sample results were compliant with the QAPP specified criteria. Five lab blanks
were analyzed and the results were non-detect for all five. All of the initial calibrations and daily
calibration verifications passed the QAPP specified criteria and are on file at the HPMG offices.

The data generated during this investigation are deemed to be of sufficient quality to be usable for their
intended purpose (see Appendix C).

4.0 RESULTS AND DISCUSSION

4.1 DATA SUMMARY

4.1.1 Soil Sample Results

The results for soil samples, which were collected from selected borings (locations NT-1, NT-2, NT-3,
ST-4, and ST-5), are presented in Table 4-1. The highest VOC concentrations were detected beneath the
slab at location NT-1, with the maximum concentration at 7 feet bgs and a relatively low concentration at
2 feet bgs. At location NT-2, at the edge of the slab, only very low concentrations were detected, and
only at 7 and 10 feet bgs. At location NT-3, in the unpaved area but immediately adjacent to the slab, all
soil samples results for VOCs were ND. All soil samples from locations ST-4 and ST-5 were also ND for
VOCs.

4.1.2 Groundwater Sample Results

The results for groundwater samples, which were collected as grab samples from selected borings
(locations NT-1, NT-3, NT-6, ST-1, ST-2, ST-4, and ST-6), are presented in Table 4-1. Similar to the
soil samples, the highest concentrations detected in groundwater were from samples beneath the slab,
with concentrations decreasing rapidly away from the slab. The maximum TCE groundwater
concentration was 240 (ig/L, which occurred in the sample from ST-1, located on the slab. The sample
from ST-2, located on but at the edge of, the slab, contained 30.4 (ig/L of TCE, and the sample from ST-
4, located approximately 30 feet from the edge of the slab, contained only 1.4 (ig/L of TCE. Similarly,
the sample from location NT-1 contained 24.7 (ig/L of TCE and the sample from location NT-3 contained
only 1.7(ig/LofTCE.

4.1.3 Macro-Purge Soil Gas Samples

The macro-purge probes were sampled multiple times over a period of four days to generate the data for a
vapor concentration profile. Specifically, probes ST1-SS, -2, and -4 were sampled three times and the
other probes were sampled twice. No probes were sampled more than once per day. Each probe was
first purged, as described in Section 3.1, prior to collecting a sample and all samples were analyzed in the
mobile laboratory. The analytical results are summarized in Table 4-2. TCE concentrations detected
along the southern transect (ST-1 through ST-6) ranged from a minimum of 62 (ig/m3 to a maximum of
26,000 (ig/m3; PCE concentrations ranged from 59 to 410 (ig/m3. In the northern transect, TCE
concentrations ranged from 120 to 6,300 (ig/m3 and PCE concentrations ranged from 74 to 92 (ig/m3.
TCE and PCE were not detected in any of the probes at locations ST-4, ST-5, or ST-6, nor in the 2-foot
bgs probe at ST-3. Similarly, TCE and PCE were not detected in any of the probes at locations NT-4,
NT-5, or NT-6, nor in the subslab or 2-foot bgs probes at NT-2, or the 2-foot and 4-foot probes at NT-3.

The mean concentrations of TCE in the soil gas from Table 4-2 were used to generate a profile of the soil
gas concentration along the sampling transect (Figure 4-1). TCE was used to generate this profile
because it was present in higher concentrations and more consistently than PCE. To better visualize the
data, isoconcentration contours are indicated in color in Figure 4-1, with darker colors representing higher
concentrations.

The profile in Figure 4-1 shows that TCE concentrations were highest in the 10-foot bgs probes, near the
water table, and decreased with increasing distance from the water table. In the horizontal direction, TCE
concentrations were highest in probes beneath the slab and decreased with increasing distance away from
the slab.

4.1.4 Micro-Purge Soil Gas Samples

Micro-purge soil gas probes were only installed along the southern transect. Each of the micro-purge
probes was sampled on at least two different days. The 4-foot bgs probe at ST-1 was sampled three
times. The samples were analyzed in the mobile laboratory operated by HPMG. The analytical results
are summarized in Table 4-3. Detected TCE concentrations ranged from 75 to 43,000 (ig/m3 and PCE
concentrations ranged from 51 to 1,200 (ig/m3. With the exception of a duplicate sample from the 4-foot
bgs sample at ST-4MP, TCE were not detected in any of the probes at locations ST-4MP, ST-5MP, or
ST-6MP; however; PCE was detected at low concentrations in the 4- and 7-foot bgs probes at ST-4MP,
the 2-foot probe at ST-5MP, and the 2- and 7-foot bgs probes at ST-6MP.

The distribution of concentrations measured in the micro-purge samples from locations ST-2MP and
ST-3MP was similar to the macro-purge samples, with concentrations generally increasing with depth and
decreasing away from the slab. The results from probes at ST-1MP were anomalous, with the maximum
concentrations measured at 4 feet bgs, and concentrations decreasing with depth from there. Figure 4-2
provides schematic isoconcentration contours for the south transect of micro-purge probes based on the
mean TCE concentration in Table 4-3. The profile in this figure highlights the anomalous data from
probe ST-1MP. These data indicate either a high (at 4 feet) secondary VOC source zone or that VOC
concentrations from the ST1MP-7 and ST1MP-10 that were inconsistently low based on the models and
groundwater concentration of TCE. Further investigation is warranted to determine the exact cause.

4.1.5 Tubing-type Cluster Samples

The tubing-type clusters consisted of six collocated probes installed at 6.25 feet bgs at locations ST-3 and
ST-6. The tubing types installed was stainless steel, Nylaflow, PEEK, Teflon, copper, and polyethylene.
The tubing-type clusters were sampled twice, on February 26 and 29, 2008. Tubing type clusters were
sampled following the same procedures and with the same purge and sample volumes as the macro-purge
probes. The results are summarized in Table 4-4.

4.1.6 Passive Diffusion Samplers

The PDSs are deionized-water filled VOA vials with trisodium phosphate (TSP) preservative and topped
with a gas-permeable membrane cap. The PDSs were inserted into PDS wells and allowed to equilibrate
with the surrounding soil gas for a minimum of 30 days. The first set of PDSs was inserted in the wells
on February 13 and removed on March 18, 2008. The second set was inserted on April 7 and removed on
May 13, 2008. The third set was inserted on May 13 and removed on June 13, 2008. The fourth set was
inserted on June 13 and removed on July 23, 2008. The fifth set was inserted on July 23 and removed on
August 26, 2008. The final set was inserted on August 26 and removed on October 1, 2008.

After removal of each PDS, the gas-permeable membrane cap was replaced with a standard VOA vial cap
with a Teflon septum, and the vial was then submitted to AETL for analysis as a normal aqueous sample.
The results were reported by AETL in units of (ig/L and are summarized in Table 4-5. In order to directly
compare these results to the corresponding soil gas concentrations of collocated probes, the PDS results
were converted to units of (ig/m3 assuming that the aqueous sample was in equilibrium with the soil gas at
the probe location when the PDS was retrieved. Thus, the aqueous sample results in units of (ig/L were
multiplied by 1,000 and the multiplied by Henry's Law constant, which is 0.421 for TCE and 0.752 for
PCE (EPA 2008). Ground water temperatures ranged from between 17 to 30 degrees C at the site. Exact
temperatures were not measured during the time of sampling so 25 degrees C was selected for the
conversion temperature. Table 4-6 summarizes the PDS results for TCE and PCE converted to soil gas
units of (ig/m3, and provides the mean soil gas concentration measured in samples from the collocated
macro-purge soil gas probes.

4.2 DISCUSSION

4.2.1 Distribution of VOCs in the Subsurface

The distribution of TCE along the primary (south) transect, based on the mean macro-purge sample
concentrations, is depicted in Figure 4-1. The data indicate that, as expected, the concentrations decrease
with increasing distance from the groundwater source. This finding is consistent with the physical
principles of subsurface vapor diffusion from a groundwater source. The data also indicate that
concentrations decrease moving horizontally out from underneath and away from the slab. This finding is
consistent with the physical effect of the slab in trapping soil vapor and preventing it from moving
vertically upward to the atmosphere.

The isoconcentration contours and concentration trends shown in Figure 4-1 are generally consistent with
those predicted by numerical models (Abreu and Johnson 2005). However, the isoconcentration contours
in the vadose zone beneath the edge of the slab are steeper than those that would be predicted assuming a
uniform groundwater concentration. Results for discrete groundwater samples from the top of the water
table (Figure 4-1, Table 4-1) confirmed that groundwater concentrations are not uniform, but decrease
with increasing horizontal distance away from the slab. IRP Site 14 groundwater data for monitoring
wells in the vicinity of the study area suggest that groundwater concentrations are higher in the deeper
parts of the aquifer; thus, there may also be a groundwater concentration gradient with depth.

Another point of interest is the concentration of VOCs at the groundwater/soil gas interface and
consistency of those results with Henry's Law. The measured soil gas concentration closest to the
groundwater at each of the probe locations was approximately 20 percent of the predicted equilibrium soil
gas concentration calculated from the groundwater concentration using the Henry's Law constant. This
finding indicates that there is a gradient across the soil gas/groundwater interface that is driving VOCs
from the groundwater into the soil gas phase.

Overall, the soil gas concentration profile shown in Figure 4-1 reflects a strong mass transfer of VOCs out
from underneath the slab and upward toward the uncovered ground surface. The mass transfer is
facilitated by concentration gradients, which exist in the soil gas, at the soil gas/groundwater interface, in
the groundwater. Collectively, these results demonstrate that soil gas and groundwater concentrations in
the vicinity of the slab are not in a state of static equilibrium but reflect a dynamic equilibrium associated
with a mass transfer effect.

4.2.2 Macro-Purge versus Micro-Purge Sampling

Paired macro-purge and micro-purge samples were collected on February 27 and 28, 2008 from 24 soil
gas sampling probes (12 macro-purge probes and 12 micro-purge probes). When collecting paired
samples, the micro-purge sample was always collected first, followed by the collocated macro-purge
sample within 5 minutes. The rationale was that the volume of soil gas removed from the micro-purge
probes was trivial (less than 5 ml) in relation to the volume removed from the macro-purge probes (-30 to
60 ml); therefore, it was assumed that purging and sampling the micro-purge probes was unlikely to effect
the results obtained from the macro-purge probes, whereas the reverse might not be true.

The paired micro-purge and macro-purge results for TCE are summarized in Table 4-7 and the data are
plotted on Figure 4-3. For the purposes of statistical testing, it was assumed that each data point is
independent, even though each soil vapor sampling point was sampled on two different days and there
were four soil vapor sampling points in each borehole. This is a reasonable assumption to make as soil
vapor migrates relatively quickly and the probe locations were separated by a minimum of 2 feet;
therefore, subsequent samples are not likely to be sampling the same material. To compare the results of
4-14

-------
the two methods, a matched pairs t-test was used on the pooled data, excluding any pairs that had a non-
detect. In order to meet the assumptions of normality, all data were natural logarithm transformed. The
results of the analyses indicate that the means of the macro-purge and micro-purge data do not differ from
each other when pooled across both sampling events and sampling locations. The following statistical
parameters were obtained through this analysis:

• Degrees of freedom (df) = 18

• t-value (t) = 0.22

• Probability (p) = 0.8.

Graphs comparing the means for each of the two sampling methods are shown in Figure 4-4.

The RPDs between paired micro-purge and macro-purge samples ranged from 122 to -198 percent
("negative" RPDs indicate micro-purge results below the paired macro-purge result). However,
excluding the results from location ST-1 at 10 feet bgs, which are clearly anomalous for the micro-probe
samplers, the RPDs range from 122 to -105 percent. If the value from ST1-10 is excluded and considered
an outlier, the maximum difference between the two methods was a factor of 4.1, with an average of 2.2
(Table 4-7). The concentrations measured in micro-purge probes were typically higher than the macro-
purge concentrations (14 of 19 measurements).

Table 4-7 also summarizes the RPDs between like samples collected on February 27 and 28 (i.e., the RPD
between the two macro-purge sample results collected from the same probe). The RPDs between macro-
purge sample results obtained on consecutive days ranged from 0 to 33 percent. This variability can be
largely explained as normal analytical error, which is typically considered to be ±25 percent. The RPDs
between micro-purge sample results ranged from 3 to 170 percent. This variability is much greater than
can be explained as analytical error, and indicates that one or more element of the micro-purge probes or
the micro-purge sampling technique introduces a significant variability to the sample results.

-------
The same data set (with NDs and results from ST1-10 excluded) was also used in a linear regression to
determine whether the results of one method could be used to predict the results of the other. The
following statistical parameters were obtained through this analysis:

df = 15

• R2 = 0.8205

• p< 0.0001.

When the non-detect results and the anomalous data from ST-1 at 10 feet bgs are excluded, the regression
is significant with p = 0.0000006 (Figure 4-5). As the results were found to be significantly related, the
macro-purge results could be used to predict the micro-purge results, and vice versa. The results of the
regressions are shown in Figure 4-5. The equation provided by the regression is as follows:

Ln(micro-purge) = Ln(macro-purge) x 0.64 + 3.1

If the two methods were identical, a slope of 1 and an intercept of zero would be expected; however, a
non-zero Y-intercept (3.1) and a slope less than 1 (0.64) indicate that there are differences between the
methods. The non-zero Y-intercept implies that with non-detect results from the macro-purge probes, one
would still get positive results from the micro-purge probes. Further review of the equation indicates that
while at low concentrations (< -5,500 (ig/m3) the micro-purge results are predicted to be higher than the
macro-purge results (as observed in the sample results), at higher concentration, the macro-purge results
are predicted to be higher than the micro-purge results. This prediction could be easily tested at a site
with higher VOC concentrations.

-------
To summarize, the statistical analyses indicate there is a correlation between the results obtained from the
two sampling methodologies; however, the range of RPDs for the macro-purge samples was 33 percent,
which is largely within analytical error, whereas the range of RPDs for the micro-purge samples was 170
percent, suggesting there are some as yet undetermined issues with this sampling method that are limiting
its reproducibility. Ignoring the samples from location ST-1 at 10 feet bgs, the paired results agreed
within a factor of 4.1, with an average factor of 2.2, and the linear regression was significant with
p = 0.0000006.

The paired micro-purge and macro-purge probes were installed at the same depths but due to drilling
equipment constraints are separated laterally by approximately 1 foot. Therefore, the differences
observed between paired micro-purge and macro-purge sample results could be, at least in part, attributed
to heterogeneities in actual soil gas concentrations over short distances in the subsurface. The significant
variability in micro-purge results obtained from the same probe over two days suggest that the
discrepancy between micro-purge and macro-purge results is more like due to issues with this sampling
method for the micro-purge probes. Further experiments with the probe construction methodology and
sampling technique are warranted to better understand the results.

4.2.3 Evaluation of Tubing Types

The tubing type clusters were sampled on February 26 and 29, 2008. With the exception of copper, the
different tubing types yielded similar TCE concentrations, ranging from 310 to 460 (ig/m3, with
polyethylene yielding the lowest concentrations on both sampling events at ST-3 (Table 4-4). The mean
and median of this range is 385 (ig/m3. If one assumes a typical analytical error of ±20 percent, then all
of these concentrations fall within analytical error of the mean and median. However, copper yielded
significantly lower concentrations, with one sample containing no detectable TCE and the second
containing only 170 (ig/m3. The reasons for these inconsistent and lower values are not clear.

A notable observation from the tubing type sampling is that there are no significant differences between
results obtained from the Nylaflow tubing versus those obtained from the stainless steel tubing. This is
important as it indicates that differences observed between the macro-purge and micro-purge sampling
results discussed in Section 4.2.1 are unlikely to be due to the fact that the macro-purge probes were
constructed with Nylaflow tubing while the micro-purge probes were constructed with stainless steel
tubing.

4.2.4 Passive Diffusion Samples

Table 4-6 summarizes the TCE and PCE results from the six sets of PDSs along with the corresponding
mean TCE and PCE concentrations from the macro- and micro-purge soil gas probes. In Table 4-6, the
PDS results are soil gas concentrations calculated from the measured water concentrations for the PDSs
multiplied by the Henry's Law constant. The calculated TCE concentrations in the PDSs were generally
higher than the corresponding measured soil gas sample concentrations, although the samples from
location ST-3 are an exception. The same observation is also apparent for PCE. This is a puzzling result,
as it is difficult to propose a mechanism that could lead to PDS concentrations exceeding equilibrium
concentrations. Perhaps the differences in soil gas concentrations between the PDSs and active soil gas
samples are due to the spatial separation of the probes or variations in soil gas concentrations over time.
Additional data are required to resolve this discrepancy.

It should be noted that the detection limit for the active soil gas samples (50 (ig/m3) is significantly lower
than for the PDSs (0.5 (ig/L, which converts to 211 (ig/m3 for TCE and 376 (ig/m3 for PCE); therefore, for
many of the low concentration probe locations, the active soil gas samples yielded positive results while
the PDS results were non-detect.

                                    5.0    CONCLUSIONS

The two primary goals of this investigation were to (1) evaluate the distribution of VOCs in the vadose
zone to improve the understanding of mechanisms of vapor migration and intrusion, and (2) develop a
robust database of paired micro-purge and macro-purge soil gas measurements with which to assess the
comparability of the two methods. Secondary objectives were to (1) assess the effect of tubing type on
soil gas sample results, and (2) assess the performance of the PDS in relation to active soil gas sampling
results. Conclusions relating to each of these objectives are listed under separate headings below.

At the NAS Lemoore site  studied, the following observations were made with respect to the  distribution
of VOCs in the sub-slab/near-slab environment:

   •   The vertical and horizontal distribution of VOCs in soil gas was generally  consistent with known
       physical principles  and the predictions of numerical models.  VOC concentrations decreased with
       distance away from  the  slab and with distance above the groundwater  table.  However, the
       isoconcentration contours near the edge of the slab were surprisingly steep.

   •   Although only a limited number of groundwater samples were taken at the surface of the water
       table, VOC concentrations in groundwater also decreased with distance away from the  slab. Thus,
       there appears to be a strong gradient in groundwater concentrations that parallels the gradient in
       soil gas concentration.

   •   Although soil gas concentrations exhibited a strong gradient in the immediate vicinity of the  slab,
       repeated measurements  over several  days indicated that the results were reproducible. Thus, the
       gradients do not appear to be the result of a short-term temporal effect.

   •   Soil gas concentrations near the water table were approximately 20 percent  of the equilibrium soil
       gas concentrations predicted from Henry's Law constants, indicating that there  is a gradient across
       the soil gas/groundwater interface.

In summary, soil gas and groundwater concentrations  in the near-slab environment appear to be in  a
dynamic  equilibrium.  Strong gradients exist to facilitate the mass transfer of VOCs out from underneath
the  slab  and  upward toward  the  uncovered soil surface.   Modeling this  environment and making
predictions regarding soil gas concentrations are challenging tasks.

The sharp gradients in soil gas VOC concentrations near the slab edge have important implications for the
use of near-slab soil gas  samples  in vapor intrusion investigations.   The results of this investigation
indicate that near-slab  soil  gas samples collected  only  a  few  feet from the edge of the slab  may
underestimate  the  concentrations present beneath the slab.   Further  research is  warranted  to evaluate
whether the near-slab vapor profile observed at NAS Lemoore IRP Site 14 is typical.

Macro-purge versus Micro-Purge

   •   Comparison of the  TCE soil gas concentrations  from the micro-purge and macro-purge methods
       showed a maximum difference of a factor of 4 with an average difference of 2.2.

   •   The statistical analyses  indicate there is a correlation  between the results obtained  from the two
       sampling methodologies; however,  the range of  RPDs for the macro-purge  samples was 50
       percent, which is largely within analytical error, whereas the range of RPDs for the micro-purge
                                                  5-1

-------
    samples was 260 percent, suggesting there are some as yet undetermined issues with this sampling
    method that are limiting its reproducibility.

Tubing Types

•   Soil gas probes constructed with stainless steel, Nylaflow, PEEK, polyethylene, and Teflon all
    yielded results within analytical error of each other,  although  polyethylene appears to yield
    somewhat lower concentrations.    Soil  gas  probes constructed with  copper  tubing yielded
    significantly lower concentrations.

•   The results  indicate that stainless  steel,  Nylaflow,  PEEK, and  Teflon  tubing  are  all suitable
    materials for probe construction, but polyethylene tubing should be avoided and copper tubing is
    not suitable for soil gas probe construction.

Passive Diffusion Sampler

•   Soil gas  equivalent TCE  concentration results for  the PDSs were  generally higher than the
    corresponding active  soil gas  sample concentrations.   Additional data is needed to more
    completely assess the performance of the PDS.
                                               5-2

-------
                                6.0    RECOMMENDATIONS

The results of this investigation have  raised a number of questions that warrant further experimentation.
The following recommendations are provided for future research.

    •   Further evaluation of the  micro-purge sampling technique is warranted to understand the source
       of the variability observed in results obtained through this  method.  It is unclear whether the
       variability is due to the probe construction method or the sampling technique.  One approach to
       evaluating this is to collect paired  soil gas samples from micro-purge and macro-purge probes,
       but collect samples from the  micro-purge probes using the  same parameters as are used  at the
       macro-purge probes. That is,  use the same purge volume (measured in ml, not system volumes),
       purge rate, and sample volume.  If the  variability is a function of sampling technique, then  it
       would be expected to be  similar between the two probe  types if when they are sampled  in the
       same manner, whereas, if the  variability  is due to the construction methodology, the varying the
       sample collection parameters would not be expected to impact the results.

    •   At the NAS Lemoore site studied, additional groundwater sampling, possibly at multiple discrete
       depths, combined with contemporaneous soil gas sampling may provide improved understanding
       of the dynamic relationship between groundwater and soil gas, and the influence of the slab.

    •   Installation of additional  soil  gas and groundwater sampling locations at the NAS Lemoore site
       studied both under the slab and in the unpaved area immediately adjacent to the slab, would help
       refine the assessment of the vertical and lateral distribution of VOCs in the subsurface.

    •   The steepness of the soil gas isoconcentration contours in the  vicinity of the slab at NAS Lemoore
       IRP Site 14 was a somewhat surprising result.  Measurement of the soil gas concentration profiles
       in the sub-slab/near-slab  environment at other sites is needed to confirm whether this result  is
       typical.

1.0 INTRODUCTION
This Trip Report provides a summary of the sampling activities that were conducted between January 14
and March 3, 2008 at Naval Air Station (NAS) Lemoore Installation Restoration Program (IRP) Site 14.
The sampling was conducted on behalf of the U.S. Environmental Protection Agency (EPA), Office of
Research and Development, in support of the project titled Vertical Distribution ofVOCs in Soils from
Ground Water to the Surface/Subslab, conducted under EPA Contract Number EP-C-05-061, Task Order
Number 65 (TO-65).

NAS Lemoore is located in the California Central Valley, approximately 40 miles south of Fresno and
180 miles northwest of Los Angeles. IRP Site 14 is located in the operations area of NAS Lemoore and
consists of maintenance buildings, hangars, and aircraft parking areas (Figure 1).

The project field team included environmental consultants from Tetra Tech (Chris Crosby, Michele
Mykris, Brian Dow, Logan Hackett, and James Elliot) and H&P Mobile Geochemistry (Blayne Hartman,
Dave Balkenbush, Mark Burke, Kurt Schindler), and drill rig operators from Interphase Environmental,
Inc. (Gilbert Mendoza and Raul Talavera). In addition to contractor personnel, the project field team
included the EPA Task Order Project Officer (Brian Schumacher) and EPA scientists (John Zimmerman
and Katrina Varner). Mr. Frank Nielson, from the NAS Lemoore environmental office, provided
logistical support and was often on-site.

The field investigation was implemented over six mobilizations. Geophysical clearance of proposed
sampling locations and concrete coring at the Building 173 slab were conducted on January 9 and 10.
Drilling and soil gas probe installation were conducted during the weeks of January 14, January 21, and
February 11. Soil gas sampling with on-site analysis was conducted the week of February 25.
Installation of the HOBO weather station was completed on March 3.

2.0 DRILLING AND PROBE INSTALLATION

Soil gas probe installation and soil sampling was conducted in accordance with the procedures detailed in
the QAPP (Tetra Tech 2007). Groundwater sampling, which was not proposed in the QAPP, was
conducted at a subset of the sampling locations to obtain data on groundwater VOC concentrations
immediately below the soil-gas and soil sampling locations. Groundwater samples were collected by
temporarily installing 1-inch diameter slotted PVC well screen in the open boreholes, allowing
groundwater to flow into the screen until the groundwater level had stabilized, and then collecting a grab
sample with a bailer.

2.1.1 Week of January 14

During the week of January 14, 2008, soil and groundwater sampling and macro-purge soil gas probe
installation were conducted at the transects proposed in the QAPP at the former Building 173 (jet-engine
test-cell) slab (Figure 2). Drilling, probe installation, and soil sampling was conducted at all 12 of the
locations proposed in the QAPP. Grab groundwater samples were collected at six of the drilling
locations. Soil sampling and soil gas probe installation was conducted at 2, 4, 6, and 8 feet below ground
surface (bgs) at each location. In addition, sub-slab soil gas probes were installed at the four locations on
the former Building 173 slab, and tubing-type clusters were installed at two locations.

EPA installed micro-purge soil gas sampling probes at the six transect locations and installed Passive
Diffusion Sampler (PDS) wells at two locations. Micro-purge gas probes and PDS wells were installed at
depths of 2, 4, 6, and 8 feet bgs at each location.

Soil gas samples were collected in Tedlar bags for off-site screening at the H&P fixed laboratory on
January 15 and 16. The results were received via telephone on January 16 and 17 and were non-detect
(ND) or very low (less than 1 (ig/L) for all compounds. Based on these results, it was determined that the
investigation area proposed in the QAPP was not suitable for the investigation. Therefore, a number of
alternative areas at NAS Lemoore Site 14 were visited to select a different area for the investigation.
Based on a review of available groundwater data and utility maps, it was determined that the most
promising area was located on, and immediately east of, the concrete parking lot adjacent to Building
170.

The soil gas probes (micro-purge and macro-purge) and tubing-type clusters were removed from the
boreholes at the Building 173 investigation area on January 17 and the soil and groundwater analyses
were cancelled. The PDS wells installed at two of the locations (four depths at each location) were left in
place. These locations are identified as NT-5A and NT-6A on Figure 2.

On January 18, a geophysical subcontractor was brought back to the site to clear the proposed alternative
investigation area east of Building 170. The new locations were cleared and macro-purge soil gas probes
were installed at locations ST-3, ST-6, and NT-4 at depths of 2, 4, 7, and 10 feet bgs (Table 1). Soil
samples were not collected from these three locations due to time constraints. The soil gas probes were
allowed to equilibrate and soil gas samples were collected in Tedlar bags for off-site screening at the
H&P fixed laboratory over the weekend.

The results were received on January 19 and TCE and PCE were found to be present in the samples at
concentrations ranging from 50 to 670 (ig/m3. A conference call between EPA, Tetra Tech, and H&P was
held on January 20 and it was decided that the investigation should proceed at the new investigation area
east of Building 170. A set of two transects were quickly laid out within this new investigation area, with
the number and spacing of planned sampling locations essentially the same as originally planned at the
Building 173 investigation area (Figure 2).

2.1.2 Week of January 21

The sampling locations along the two transects at the new investigation area, east of Building 170, were
identified as ST-1 through ST-6 along the south transect and NT-1 though NT-6 along the north transect
(Figure 3). On January 22, concrete coring was conducted at the four locations that were on the concrete
slab of the Building 170 parking lot (NT-1, NT-2, ST-1, and ST-2). Drilling, soil sampling, and macro-
purge soil gas probe installation were conducted at locations ST-4, ST-5, and NT-3. Soil sampling and
soil gas probe installation were conducted at 2, 4, 7, and 10 feet bgs (Table 1). Grab groundwater
samples were collected at locations ST-4 and NT-3.

On January 23, the field team attempted to continue drilling and soil gas probe installation. It had been
raining overnight and was raining heavily on January 23. The first location attempted was ST-2, which is
on the concrete slab of the parking lot. The location was drilled to 4 feet bgs; however, when the drill rod
was removed from the borehole, it immediately filled with water. A bailer was obtained and an attempt
was made to bail the water out of the borehole; however, the borehole immediately filled up again with
water and it was determined that significant amounts of run-off were flowing under the concrete slab and
filling the borehole. As these conditions precluded the installation of soil gas probes, an attempt was
made to drill at NT-6, located off the concrete slab. However, the drill rig quickly got stuck in the mud
before reaching the sampling location. Based on these conditions, it was decided not to continue the
drilling program until the rain stopped and the ground had dried out. The weather forecast called for
continued rain through the following week; therefore, the field investigation was put on weather hold.

The micro-purge probe installation protocol does not require construction of the probe in an open hole;
therefore, the micro-purge probe installation was not impacted by the under-flow of rain water beneath
the slab and EPA installed micro-purge soil gas probes at locations ST-1 and ST-2 on the concrete slab.

2.1.3 Week of February 11

On February 11, soil and grab-groundwater sampling and macro-purge soil gas probe installation was
conducted at locations ST-1 and ST-2 (Figure 3, Table 1). Soil gas probes were installed sub-slab, and at
2, 4, 7, and 10 feet bgs. Soil samples were collected from 2, 4, 7, and 10 feet bgs. EPA installed micro-
purge soil gas probes at 2, 4, 7, and 10 feet bgs at locations ST-5 and ST-6.

On February 12, soil sampling and macro-purge soil gas probe installation was conducted at locations
NT-1, NT-2, NT-5, and NT-6 at 2, 4, 7, and 10 feet bgs. In addition, sub-slab soil gas probes were
installed at NT-1 and NT-2. Grab groundwater samples were collected at NT-1 and NT-6.

As discussed in Section 2.1.1, due to time constraints, soil samples were not collected at locations ST-3,
ST-6, and NT-4 when the soil-gas probes were installed on January 18. This was discussed with Brian
Schumacher in the field, and it was agreed that soil samples should be collected at locations ST-3 and
ST-6, but were not necessary from NT-4. On February 12, a new borehole was drilled immediately
adjacent to location ST-6 and soil samples were collected at 2, 4, 7, and 10 feet bgs and a grab
groundwater sample was collected. On February 13, a new borehole was drilled immediately adjacent to
location ST-3 and soil samples were collected at 2, 4, 7, and 10 feet bgs.

Tubing-type clusters were installed at locations ST-3 and ST-6 at 6.5 feet bgs on February 13. The
tubing-type clusters consisted of a bundle of six different tubing types, each with a gas-permeable tip,
installed similarly to the other macro-purge soil gas probes, with the exception that the sand pack was 18
inches rather than 6 inches. The rationale was that while the regular macro-purge probes were intended to
sample a specific depth, the objective of the tubing-type clusters was to assess the effect of tubing type on
measured soil gas concentrations, and the longer sand pack would better accommodate the larger purge
volume that would be associated with purging multiple probes (each tubing type) in quick succession.
The tubing types were stainless steel, copper, polyetheretherketone (PEEK), Teflon, Nylaflow, and
polyethylene. All of the tubing types were 1/8-inch diameter with the exception of the polyethylene,
which was only available in 1/4-inch diameter.

On February 13, EPA completed installation of the micro-purge soil gas probes at locations ST-1, ST-2,
ST-3, and ST-4 and constructed PDS wells at locations ST-1, ST-2, ST-3, and ST-5 (Figure 2). Micro-
purge soil gas probes and PDS wells were installed at depths of 2, 4, 7, and 10 feet bgs.

3.0 SOIL AND GROUNDWATER SAMPLE ANALYSES

Soil and groundwater samples were submitted to American Environmental Testing Laboratory, Inc.
(AETL) in Burbank, California for VOC analysis via EPA method SW8260B.

Due to the low concentrations of soil gas detected in the screening soil gas samples (Section 2.1.1), three
soil samples collected on January 22 (ST4-4, ST4-7Q, and ST4-10) were submitted to AETL for VOC
analysis on a 24-hour turn-around-time basis. The results for all three samples were ND for all
compounds; therefore, the remaining soil samples collected on January 22 and all subsequent soil samples
were archived at the laboratory pending a decision from EPA on which samples should be analyzed.

SOIL GAS SAMPLING AND ANALYSIS
Soil gas sampling was conducted during the week of February 25.  An on-site mobile laboratory from
H&P was used to analyzed soil gas samples. Macro-purge soil gas probes were purged using disposable

60-ml polypropylene syringes attached to 3-way Swagelok valves and samples were collected in the
syringes after purging.

Purge tests were conducted at five different macro-purge probes. On February 25, purge volume tests
were conducted at probes NT4-10, ST1-10, and ST3-10. At probes NT4-10 and ST1-10, samples were
collected after purging 1, 2, and 5 system volumes and at probe ST3-10 after purging 2, 3, and 5 system
volumes. On February 26, purge volume tests at 2, 3, and 5 system volumes were conducted on probes
ST2-10 and ST4-10. The system volumes for each probe are indicated on Table 1. Based on the results
of the purge tests, a purge volume equal to 3 system volumes was selected for the sampling program.

Micro-purge soil gas probes were purged and sampled using glass syringes provided by EPA. A single
system volume was purged from each micro-purge probe followed by collection of a 2.5 ml sample.
System volumes for the micro purge probes were assumed to be 2.0, 2.1,2.1, and 2.2 ml for the 2-, 4-, 7-,
and 10-foot deep probes, respectively.

A total of 206 soil vapor samples were collected from February 25 through 29. These comprised 15
purge volume test samples, 118 macro-purge samples (including 12 duplicates), 49 micro-purge samples
(including six duplicates), and 24 tubing cluster samples. Each soil gas probe was sampled a minimum of
two times during the sampling program.

5.0 AUTO-SAMPLER INSTALLATION

The auto-sampler and HOBO weather station were deployed on February 29 and March 3. The auto-
sampler was integrated with 13 of the macro-purge probes along the southern transect:

• ST1-SS
• ST1-2
• ST1-4
• ST1-7
• ST2-SS
• ST2-2
• ST2-4
• ST2-7
• ST3-2
• ST3-4
• ST3-7
• ST4-2
• ST4-4

These probes were selected as they provided three complete vertical profiles at the locations that had the
highest measured VOC concentrations. In addition, selection of four adjacent locations along a single
transect provided logistical advantages.

The HOBO weather station was set up to measure ambient temperature, barometric pressure, relative
humidity, wind speed, wind direction, and rain fall. In addition, soil moisture probes, integrated with the
HOBO weather station, were collocated with vapor probes ST1-4, ST3-2, ST3-4, ST3-7, ST4-2, and
ST4-4.

6.0 FIELD QUALITY CONTROL
Duplicate field samples were collected at a rate of approximately 11 percent for macro-purge samples and
14 percent for micro-purge samples. This exceeds the requirements of the QAPP.

Leak tests were conducted at five of the 2-foot bgs macro-purge probes: ST2-2, ST4-2, ST6-2, NT1-2,
and NT3-2. The leak tests were done at the shallowest probes (i.e. 2 feet bgs) as these are considered the
most likely to leak as they have the shortest column of hydrated bentonite to seal out ambient air. All five
of the probes passed the leak tests, with no leak-test compound detectable in the samples. Based on these
results, the probes were assumed to be well sealed and no additional leak tests were conducted.

7.0 HEALTH AND SAFETY

Each field team member was required to sign a form acknowledging they had received and understood the
site-specific health and safety plan. Each day of field work began with a Tailgate Health and Safety
meeting followed by equipment checking and preparation. The daily health and safety meetings were
conducted by the Tetra Tech site supervisor and covered site-specific health and safety concerns including
physical, chemical, and biological hazards.

There were no accidents or other health and safety incidents during the field program.

STANDARD OPERATING PROCEDURE
PREPARATION AND IMPLEMENTATION OF NEW PASSIVE DIFFUSION SAMPLERS
FOR GROUND WATER AND/OR SOIL GAS

1. Disclaimer

This standard operating procedure has been prepared for the use of the Groundwater and
Ecosystems Restoration Division of the U.S. Environmental Protection Agency and may not be
specifically applicable to the activities of other organizations. THIS IS NOT AN OFFICIAL
EPA APPROVED METHOD. This document has not been through the Agency's peer review
process or ORD clearance process.

2. Purpose (Scope and Application)

This document describes the procedure used to collect ground water and/or soil gas
samples at contaminated sites where vertical contaminant profiling of VOCs (Volatile Organic
Compounds) is important for site characterization and risk assessment. The procedure employs
the use of a newly developed passive diffusion sampler (PDS).
3. Method Summary

Passive diffusion samplers are constructed using 40 ml VOA vials where the Teflon septa
is replaced with a permeable membrane. The PDS is inserted into a custom-made messenger and
deployed down monitoring wells which have been installed with 2-inch diameter screened
intervals. The permeable membrane in the PDS is exposed to the screened-interval and
contaminants diffuse through the membrane into the water-filled PDS. The PDS are recovered
from the wells after an appropriate equilibration period, typically one month for most VOCs, and
analyzed for contaminants of concern.

4. Reagents/Chemicals/Gases

Trisodium phosphate (TSP) NasPO^ dodecahydrate - directly from the vendor.

5. Equipment/Apparatus

• PDS Vials - 40 ml VOA vial fitted with modified caps where the Teflon® septa is
replaced with a 25 mm diameter Supor® membrane (0.2 |im pore size). A 15 mm
hole is punched through the center of the Teflon-faced silicone rubber septum.
The 25 mm diameter Supor® membrane is inserted into the screw cap. The
Teflon-faced silicone rubber septum containing the hole is used as an o-ring to
hold the membrane in place, with the Teflon-faced side facing the mouth of the 40
ml vial.

• Messengers - used to hold the PDS within the monitoring well.

• Safety cable hooked to the top of the messenger. The cable is used to retrieve the
messenger and PDS vial from monitoring wells. The cable should be of sufficient
length to extend from the installed messenger to the top of the well, with enough
excess rope to attach securely at the surface.

• PVC Rod - in excess of well depth, used to push the messenger down to the
bottom of the monitoring well.

• Peristaltic pump - used to evacuate air within the monitoring well as the
messenger is lowered into the well. This eliminates potential geochemical
alteration from air being pushed into the formation.

• PDS Vials are labeled with unique sample identifiers prior to being deployed in
monitoring wells.

• Chain of custody forms for sample shipment to the analyzing laboratory.

• Ice and ice chest for shipping samples to laboratory.

6. Health & Safety Precautions

Standard field safety procedures must be followed at all times.

7. Interferences

       VOA samples are subject to contamination by volatile compounds via diffusion through
the septa. Care should be taken to  store samples to maintain their integrity, i.e.,  away from
sources of possible  contamination,  such  as standards  or samples known  to  contain  high
concentrations of volatiles.

8. Procedure

Construction of Passive Diffusion Samplers

       The passive diffusion sampler (PDS) is a 40 ml VOA vial fitted with modified caps
where the Teflon® septa is replaced with a 25 mm diameter Supor® membrane (0.2 jim pore
size) (Figure  1). A 15 mm hole is punched through the center of the Teflon-faced silicone rubber
septum. The 25 mm diameter Supor® membrane is inserted into the screw cap. The Teflon-
faced silicone rubber septum containing the hole is used as an o-ring to hold the membrane in
place, with the Teflon-faced side facing the mouth of the 40 ml vial. Each PDS is loaded with 0.4
±0.1 gram of trisodium phosphate  dodecahydrate as a preservative, then 40 ml deionized water
is added to each vial. The vials are  capped and the cap is covered with parafilm to prevent
dehydration. The parafilm is removed prior to deploying in monitoring wells.

   Construction of Messengers

   •   High density polyethylene (JdDPE) round stock (2.05"dia.) is cut to length (6.25") and
       placed in a lathe chuck.

   •   The ends are faced using a parting tool. The final length is 6.0".

   •   A 7/16" drill bit is used to drill a 0.435" diameter, 3.0" deep hole in one end (top end).

   •   A 1.125" hole is drilled to a depth of 3.75" in the other end (bottom end). This is for
       placement of the PDS vial.

   •   The locations of the two sealing vanes are marked on the outside of the stock. (1.10" and
       3.40" from the bottom end.

• Using a parting tool, two 0.15" grooves (vane detent) are cut to create each 0.04" thick
vane.

• The JrtDPE shaft is turned down to an outside diameter of 1.95", leaving the vanes at
2.05" diameter.

• The 0.435" hole at the top of the messenger is threaded to accommodate a 0.25"
compression fitting for the pump tubing.

• A stainless steel eye bolt (0.02 X 1.0 inch) is threaded into the large opening end to hold
the PDS vial.

• Using the 0.25 inch compression fitting as a fastening point, 1/16 inch diameter stainless
steel, plastic coated braided wire is stripped to 1.0" and the wire is wrapped around the
threaded shaft of the compression fitting between the two thread points. A 0.0626"
aluminum crimp ferrule is used to secure the wire around the shaft.

• 0.25" pump polyethylene tubing is attached to the messenger via the compression fitting.
The tubing accompanies the retrieval wire to the top of the well casing after the
messenger is deployed within the monitoring well. This is secured to an ExCap (quick
connect vented J-plug).

Monitoring System

The monitoring system consists of a cluster of 2-in diameter PVC monitoring wells
installed at discrete depths with 2-in screened intervals (Figure 2). The messenger containing the
PDS is lowered into each monitoring well so that the cap of the PDS is exposed within the well
screened interval. The PDS is left in the monitoring well for approximately one month.
PDS Messenger Insertion

The PDS vial is inserted into the bottom of the messenger so that the cap is exposed at the
bottom of the messenger (Figure 3). A zip tie is looped through the eyebolt on the bottom of the
messenger and around the vial cap and closed to secure the vial within the messenger. The
messenger is lowered into the top of the monitoring well.

The peristaltic pump is connected to the tubing extending from the top of the messenger.
The peristaltic pump is turned on at a rate of approximately 1 L/min for one minute to evacuate
air inside the well casing below the messenger. The messenger is lowered one foot following
every minute of air purging.

The PVC rod is used to push the messenger into the monitoring well. The depth of the
well and screened interval is known. This depth, minus the length of the messenger, is measured
and marked on the PVC rod. The rod is lowered until the marked depth is reached.

Secure the safety cable to the well cap before closing the well.

PDS Messenger Retrieval

The PDS is retrieved after a minimum equilibration time of one month by pulling on the
sampler retrieval cable. After the PDS has been recovered, the modified screw cap is
immediately replaced with a screw cap fitted with a solid Teflon-faced silicone rubber septum.
Samples are placed on ice for storage and shipment to the laboratory for analysis.
9. QA/QC

• This procedure is to be carried out by trained personnel.

• Trisodium phosphate is added to each PDS vial prior to filling with water. The 1%
concentration (0.4 gm) is in excess of the amount needed to preserve the sample against
bacterial degradation. All samples must be analyzed within the determined holding time
period for each particular analysis.

• Field duplicate samples can be obtained by splitting a sample into two 40 ml VOA vials
and diluting with deionized water. This should be conducted in the laboratory so that
accurate weights can be obtained for correcting data after analysis.

• Spiking known concentrations of contaminant(s) of interest into selected samples
may be desirable.

• Each porous membrane will be used for only one sampling event.

• Latex or other lab gloves (unpowdered) will be worn when weighing TSP and placing it
in the PDS vials and adding water to the PDS vials.

• Torn or broken membranes will not be used.

• The PDS vials will be checked for air bubbles prior to placing them in the messenger.

• Several samples of the water used to fill the PDS's shall be retained in the laboratory and
one or more will be submitted along with the samples for analysis of analytes of concern.

• A trip blank (VOA vial filled with blank water) will be included with VOA samples in
each ice chest.

10. Calculations

Because the data are reported as mg/L in water, the contaminant concentration in soil gas
is calculated by multiplying the concentration of contaminant of concern in water (mg/L) by the
dimensionless Henry's Law Constant, then dividing by the molecular weight of the specific
contaminant of concern.

11. Miscellaneous Notes

• No purging, pumping, or external energy source is required because sampling is
accomplished through natural diffusion across the membrane.

• Since no well purging is required, the quantity of waste water is significantly
reduced.

• The PDS allows for sampling soil gas in the vadose zone, which is then converted from
an aqueous concentration of |ig/L to ppmv or mg/M3 for vapor concentration.

• The PDS allows sampling from a very discrete subsurface zone.

• High sample integrity is maintained because the membrane cap is immediately
replaced upon retrieval from the well. There is no sample transfer, further reducing
concentration losses from volatile organic compounds (VOCs).

   •  The PDS is portable and can easily be moved from well to well for comprehensive soil
      gas and groundwater sampling at any given site and may provide solution for sampling
      tight formations.

Hi Jim,

As we  discussed,  the additional samples from Lemoore are  dependent upon
the results  from  the rush  turn samples.   I just received  the  results
from the  rush  turn samples,  and they are  all ND.  I need  to talk to the
client about the  additional  samples you picked up today to  see If he
wants  to  go  forward with them,

I will get jbacfc to you shortly on that.

Subject: Samples from last week

Hi Jim,
Finally heard back from the client on the soil samples. These are the samples collected from Lemoore Site 14 on
1/22/08, and picked up by your Courier on 1/24/08.

At this time, we would like to go ahead and analyze the soil samples labeled NT3-10, ST5-1Q, and Field Dup4.
We would also like to have all three of the water samples analyzed: ST4-GW, NT3-GW, and the trip blank.

Please continue to hold the remaining soil samples, as we may analyze those depending on the what we see with
the ones listed above.

As always, feel free to call or email with questions.

Thanks
James Elliot
