                                INTRODUCTION

     EPA's Office of Air Quality Planning and Standards (OAQPS) is
developing an air emissions data base for treatment, storage, and disposal
facilities (TSDFs) in support of a background information document.   The
emissions data base will include fugitive air emissions from landfills,
surface impoundments, storage tanks, containers (drums),  solvent recovery
processes, and land treatment technologies at TSDFs.  Although the  fugitive
emissions from such sources may include a variety of inorganic and  organic
particulate emissions and vapor phase inorganic and organic emissions,  the
current emphasis is on volatile organic compounds.

     Data for the air emissions data base are being obtained through both
direct measurements and predictive models.  Sampling approaches have been
                                                    1 2
developed and demonstrated for emission measurements '  and sampling and
analytical protocols documented for obtaining field data for input  to the
predictive models (Section 5.0). '   TSDFs are identified and screened  as to
their representativeness and suitability for sampling.  During the  prelimi-
nary visit to a site, process data are obtained and grab  samples collected.
Based upon this information, the site may be selected to  perform emission
measurements.  This test report documents the results of  such emission
measurements at the IT Corporation, Benicia facility.

1.1  SITE DESCRIPTION

     Benicia is a commercial hazardous waste management facility located
northeast of San Francisco, California.  The current owners (IT Corporation)
took over the site in 1975.  The site accepts a variety of hazardous wastes.
                                    1-1

-------
Potential air emission sources at the site include:

     •    active landfill, and
     •    surface impoundments.

1.2  TESTING PROGRAM

     Emission measurements were performed at the Benicia facility June  25
and 26, 1984.  Testing was conducted by Radian Corporation,  under the direc-
tion of Dr. Charles Schmidt.  Process data were obtained by  a  representative
from GCA/Technology Division, Bedford, Connecticut,  under contract to EPA,
and representatives from the Environmental Protection Agency observed
testing.  The objectives of the testing program were:

     •    to obtain emission rate data at the active landfill  using
          the emission isolation flux chamber approach;

     •    to obtain data on the concentration of volatile organic
          compounds in the landfill soil/waste for comparison  to
          compounds identified during emission measurements  and as
          future input to predictive models; and

     •    to obtain data on the concentration of volatile organic
          compounds in the surface impoundments as future input to
          predictive models.
                                    1-2

                                 SECTION 2
                     SUMMARY AND DISCUSSION OF RESULTS

     A summary of the field sampling and analysis performed for the  IT
Benicia facility is shown in Table 2-1.  The field tests  at this TSDF have
provided data on the emission rates of volatile organic compounds (VOCs)
from the active landfill.  The average emission rates measured  for select
compounds emitted from the landfill are shown in Table 2-2.  The compounds
shown represent a list of major hazardous waste constituents identified by
EPA personnel and which could be detected (1 ppbv-C)  by the analytical
system.  For a complete list of compounds detected, refer to Appendix D,
Analytical Results.  In general, the volatile compounds detected from the
                                    4
flux chamber samples corresponded to the compounds detected in  the soil core
samples (Table 2-6).  The results of the emission measurements  indicated two
areas of significantly different emissions; specifically, a moist unloading
area and the larger area where the waste was spread.   It  is expected that
the data obtained are representative of the landfill as a whole, for the
conditions under which the measurements were made.

     Additionally, data were obtained on the VOC composition of a number of
the surface impoundments at the facility.  These individual samples  may not
necessarily be representative of the pond's composition.   The quantity of
volatile organic compounds in these ponds ranged from 2 mg/L to 20 mg/L
TNMHC.

     A more detailed presentation of the data are provided in the sections
below.

2.1  ACTIVE LANDFILL

     Emission rates measured at the active  landfill using the flux chamber
are tabulated in Table 2-3, as calculated using  the results of the canister
samples.  Also shown are the average emission rates and  the associated 95%
confidence intervals.  The variability between emission  rates measured at
individual gridpoints is generally at the same level as  the sampling and
analytical variability associated with the  flux  chamber  measurement tech-
nique (see Section 6).  The variability of  the emission  rates between grid-
points, based on the on-site analyses, was  consistent with the canister
results.  This implies that the differences between gridpoints are not
significant, and that the average emission  rate  is representative of the
gridded area of the landfill as a whole. Note that the  emission rates
measured at gridpoint 1' are significantly  different than the other grid-
points.  This location was in a separate section of the  landfill which was
not considered part of the gridded area (see Section 4).

     Soil cores were obtained at each of the locations where flux chamber
measurements were made.  The results of the analyses of  these cores are
presented in Table 2-4, along with the average concentrations and 95% confi-
dence intervals.  The variability between concentrations at individual grid-
points was compared to the sampling and analytical variability of the soil
core procedure (see Section 6.0).  Generally, the variability between cores
is slightly greater than the sampling and analytical variability alone,
indicating that the differences between cores (gridpoints) may be signifi-
cant.  The spatial variability for the soil cores is greater than that shown
by the flux chamber measurements.

     Table 2-5 summarizes additional physical data for the soil at the
landfill.  The soil temperatures varied with the time of day, showing typi-
cal diurnal trends.  Differences between soil temperatures inside and out-
side the flux chamber were typically less than 2°C.  Soil moisture, bulk
density, and specific gravity were measured for  a single soil sample and the
associated soil porosity calculated.  This  data  may not  necessarily be
                                    2-4

representative of the landfill as a whole.  It was  observed  that the un-
loading area was more moist in general than the spreading  area.

     The measured emission rates were compared to the  results of the soil
core analyses in order to verify that the flux chamber was measuring emis-
sions from the landfill.  Table 2-6 presents this comparison for each of the
individual gridpoints.  Qualitatively, the flux chamber generally did detect
the volatile components in the soil.  A quantitative comparison was made
based upon a comparison of mass transfer coefficients  (i.e., emission
rate/concentration) implied from the comparison in  Table 2-6.  The tabulated
mass transfer coefficients are listed in Table 2-7  for each  of the indivi-
dual gridpoints, the resulting averages (Method 1)  and for the average
emission rate and core concentrations for the landfill (Method 2).  No
attempt has been made to normalize the mass transfer coefficients for tem-
perature.  A general agreement from gridpoint to gridpoint for an individual
compound would imply good inherent precision in the sampling and analytical
methods (i.e., flux chamber and soil cores).  The physical reasonableness of
the 'values for the individual compound mass transfer coefficients would
imply that there is no large bias for the measurements of  the specific
compounds .

2.2  MISCELLANEOUS SURFACE IMPOUNDMENTS

     Liquid samples were obtained from the selected surface  impoundments
within the facility.  Grab samples were collected from one or two locations
in the impoundment, depending on the physical appearance of  the surface.
While these samples may not necessarily be representative  of the individual
impoundments as a whole, they can be used as an indication of the composi-
tion.  Table 2-8 lists the results for samples from each of  the impound-
ments.

                                 SECTION 3
                            PROCESS DESCRIPTION

     The following section details the treatment,  storage,  and  disposal
facilities found at the IT facility.  Each operation type is  discussed
separately.  A general plot plan of the facility is shown in  Figure 3-1.

3.1  PROCESS DESCRIPTION

3.1.1  Landfill

     The open landfill covers approximately 17,000 square meters  and is
contained within the confines of the natural topography and an  earthern
embankment.  No liner is used because of the low permeability of  the natural
soil (clay).  The landfill does not include any type of leachate  collection
system, nor any gas ventilation.  This landfill has been worked for approxi-
mately four years.  One more lift is planned for the landfill before closing
it.  The landfill accepts only hazardous waste, primarily inorganic pig-
ments, solids such as organic contaminated soils,  and organic sludges.  No
liquids are accepted into th.e landfill, and no fixation is  performed. Any
drums that are received are crushed prior to placement into the landfill.

     Material is unloaded in the north corner and  spread over the surface by
bulldozers.  Compactors then go over the waste surface, prior to  additional
waste being spread.  Periodically dirt is brought  in to be  mixed  with the
waste being spread, but no attempt is made to cover the landfill  on a daily
basis.  Activity at the landfill is on an as-needed basis.

3.1.2  Surface Impoundments

     The receiving pond (17) covers approximately 2 acres  by 15  feet deep
and accepts oily materials.  No chlorinated organics,  or organic wastes with
concentrations of volatile organic compounds greater than  300 ppm TNMHC, are
accepted into the pond.  All incoming wastes are tested  prior to being
processed.  Pond 17 also receives run-off from the washing out of trucks
bringing waste to the site.  At the time of the site visit, 50%  of  the
surface of pond 17 was sludge.  The remaining liquid surface had a  visible
oily layer.  A second pond (18) also receives organic  wastes. This pond is
approximately an acre in size and 10 feet deep.

     Ponds-0, P, and Q are used to store TiC^ sludges.  These sludge ponds
are cleaned on a regular basis, while the other ponds  are  cleaned on an as-
needed basis.

3.1.3  Sludge Drying Area

     The sludge drying area (13A) covers 1.5-2 acres.  The sludges  applied
to this area include wastes from the facility ponds and  wastes from other
generators.  Application of sludges to this area is not  conducted on a
routine basis.  At the time of the site visit, there was no activity in this
area, and apparently there had not been any for some time.

3.2  WASTE CHARACTERIZATION

     IT Corporation accepts a variety of hazardous waste at this facility.
Tables 3-1 and 3-2 provide a listing of the waste materials received at this
site during the month of June 1984 (i.e., June 1 through 26, 1984.)

                             SAMPLING LOCATIONS

     The following section presents the location of sampling activities at
the TSDF.  Included are schematic diagrams showing the emission sources and
sampling grids, the rationale for the sampling point  selections, and any
statements necessary to qualify or limit the  results.  The presentation has
been organized by source.

4.1  ACTIVE LANDFILL #1

     The active, or open, landfill is shown in Figure 4-1.  The sampling
grid was established over the eastern side of the landfill and included
approximately 93% of the total exposed area.  The western side of the land-
fill was only sampled at one, non—randomly selected point due to the ex-
tremely moist sampling surface and the relatively small surface area of this
side.  Figure 4-1 shows the location of the sampling  points.  Sampling
points within the grid were randomly selected.  The area appeared to be
homogeneous.  The sampling locations are thought to be representative of the
landfill as a whole.  At each point, emission measurements were made using
the flux chamber and soil core samples collected.

4.2  RETENTION PONDS

     The site includes a number of surface impoundments situated in a cas-
cading fashion in the site's hills.  Single grab samples were collected near
the bank at each pond where sampling was feasible.  Samples may not neces-
sarily be representative of the average composition for each pond.

                                 SECTION 5
                     SAMPLING AND ANALYTICAL PROCEDURES

     This section describes those procedures used for sample collection and
analysis.  Included are discussions of air emission measurement  approaches,
air, solid and liquid sampling and analytical techniques.

5.1  AIR EMISSION MEASUREMENTS

     Air emission measurements were made using two approaches, specifically:
emission isolation flux chamber and mass balance.  These approaches are
described below, and should be differentiated from the sampling  and analyti-
cal techniques used to collect and/or analyze the samples.   The  sampling and
analytical techniques associated with these approaches are  described  in
Sections 5.2, 5.3 and 5.6.

5.1.1  Emission Isolation Flux Chamber

     The emission isolation flux chamber is a device used to make  a direct
emission measurement.  The enclosure approach has been used by researchers
to measure emission fluxes of sulfur and volatile organic species. '  '
The approach uses an enclosure device (flux chamber) to sample gaseous
emissions from a defined surface area.  Clean, dry, sweep air is added  to
the chamber at a fixed controlled rate.  The volumetric flow rate  of  sweep
air through the chamber is recorded and the concentration of the species of
interest is measured at the exit of the chamber.   The emission rate is
expressed as:
                                 Ei = Ci.R/A                    (Equation  1)
                                    5-1

-------
where ,
     E^ = emission rate of component i, yg/m -sec
     C^ = concentration of component i in the air flowing  from the  chamber,
                                                 o
      R = flow rate of air through the chamber, m /sec
                                                 o
      A = surface area enclosed by the chamber, m

All parameters in Equation 1 are measured directly.

     A diagram of the flux chamber apparatus used for measuring  emission
rates is shown in Figure 5—1.  The sampling equipment consists of  a  stain-
less steel/acrylic chamber with impeller, ultra high purity  sweep  air and
rotameter for measuring flow into the chamber,  and  a sampling manifold for
monitoring and/or collection of the specie(s) of interest.   Concentrations
of total hydrocarbons are monitored continuously in the chamber  outlet gas
stream using portable flame ionization detector (FIB)- and/or photoioniza-
tion detector (PID)-based analyzers.  Samples are collected  for  subsequent
gas chromatographic (GC) analysis once a steady-state emission rate  is
obtained.  Air and soil/liquid temperatures are measured using a thermo-
couple.

     To determine the emission rate for a source of much greater area than
that isolated by the flux chamber, a sufficient number of measurements must
be taken at different locations to provide statistical confidence  limits for
the mean emission rate.  The area sources measured  were gridded  and  a mini-
mum of six (6) measurements made (when possible) to account  for  spatial
variability.  Additionally, a single point was  selected as a control point
to define temporal variability.  On-site GC analyses were performed  for all
flux chamber measurements and canister samples  were collected for  each area
to allow off-site, detailed GC analysis.  Prior to  using the chamber, blank
and species recovery data were obtained.

5.2  AIR SAMPLE COLLECTION

     Two methods were used to collect air samples for analysis  during  the
sampling discussed above.  A gas tight syringe was used to collect  gas
samples for analysis on site using a gas cbromatograph (GC) and evacuated
stainless steel canisters were used to collect gas samples to be shipped  to
Radian's Austin laboratories for detailed GC analysis.  The gas tight
syringes were 100 cc volume, constructed of glass and teflon, and protected
from sunlight.  Gas aliquots were taken from the syringe for injection into
the on-site GC (Section 5.5.2).

     The stainless steel canisters were cleaned and evacuated in Radian's
Austin, Texas laboratories and sent to the field.  The canister sampling
system included a sintered stainless steel filter to protect the system from
suspended particulate matter and a vacuum flow regulator to provide a  con-
stant sampling rate over the 20-minute sampling periods.  Following sample
collection, the canisters were shipped back to Radian's laboratories.   The
canisters were pressurized to 10-15 psig with UHP nitrogen to provide  posi-
tive pressure for removing the sample for analysis and to dilute oxygen and
moisture in the sample to minimize sample component reactions.   Canister
dilution is calculated from the absolute pressure before and after  sample
collection, and after addition of UHP N2.

5.3  LIQUID SAMPLE COLLECTION

     Liquid samples were taken from surface impoundments for volatile  or-
ganic analysis (VOA) using the purge and trap technique (Section 5.5.3).
Samples were collected following the guidelines outlined in ASTM D3370,
"Standard Practices for Sampling Water."  Samples were collected in glass
VOA vials with teflon-lined caps.  The VOA vials were filled to the brim  and
capped.  Samples  were stored at reduced temperatures prior to analysis.
                                    5-4

-------
5.4  SOIL SAMPLE COLLECTION

     Soil samples were collected for volatile organic analysis using a
headspace technique (Section 5.5.3).  Samples were collected with  a thin
wall, brass core sampler.  The sampler (Figure 5-2) was  driven or  pressed
into the soil surface far enough to fill the sampler, but not compress the
soil core.  The sampler was then removed and the ends capped.  Samples were
stored at ambient temperatures prior to analysis.

     Bulk soil samples were also collected for measurement  of moisture
content and specific gravity.  These samples were typically composites ob-
tained using an open-blade type auger.  Samples were placed in glass jars
and sealed to prevent moisture loss.

5.5  ANALYTICAL TECHNIQUES

     The analytical techniques used on site are discussed in Sections 5.5.1
and 5.5.2 while the off-site analytical techniques are discussed in Sections
5.5.3 and 5.5.4.  A mobile laboratory served as a base of operation during
field testing.

5.5.1  Real-Time Monitors

     Real-time continuous monitors were used on site to  determine  general
levels of THCs and to indicate the point in time at which gas syringe and
gas canister samples should be collected.  For example,  the instruments were
used to determine when steady-state conditions had been  reached during flux
chamber measurements, and to survey potential sampling points at the drum
storage and handling area.  The following monitors were  available  during the
field tests:  HNU Model PI-lOls, Century System Model OVA-108s, and AIL,
Inc. Model 580.  Performance data on the monitors are summarized in Table
5-1.

5.5.2  On-Site Gas Chromatographs

     The HNU field portable GC-FID/PID was used to provide  rudimentary
speciation data and total hydrocarbon data on air samples  (syringe)  col-
lected during flux chamber measurements.  The GC was  operated  in  an  isother-
mal mode with a 20% SP-2100/0.1% CW1500 column.  Quantitation  was based on
standards of benzene in hydrocarbon-free air.  Retention times were  gener-
ated from a multicomponent standard.  Instrument conditions are summarized
in Table 5-2.

5.5.3  Off-Site Gas Chromatographs

     All gas canister samples and selected solid and  liquid samples  were
analzyed in Radian's Austin laboratories for £2^10 hydrocarbon species
using a Varian Model 3700 gas chromatograph.  Sample  analysis  involved
cryogenic concentration, gas chromatographic separation, detection by mul-
tiple detectors,-and data evaluation.  The use of multiple  detectors pro-
vided species-specific response for halogenated compounds  (Hall Electrolytic
Conductivity Detector - HECD), unsaturated compounds  (photoionization detec-
tor - PID), and hydrocarbon species in general (flame ionization  detector -
FID) .  The liquid samples were analyzed using a purge and  trap technique
modified to integrate with the cryogenic concentration.  The solid samples
were analyzed using a headspace technique with direct syringe  injection.
Speciation was based upon retention times relative to toluene, toluene
normalized response factors, and specific halogenated standards.   VOCs were
quantitated against propane and hexane standards and  reported  as  ppbv-C and
mass concentrations of the compound based upon molecular weight.   Utiliza-
tion of this gas chromatography system with multiple  detectors has been
                     Q
previously described.   A diagram of the system is shown in Figure 5-3
and the operating conditions are listed in Table 5-3.

                                DATA QUALITY

     There is always some amount of uncertainty associated with any measure-
ment data due to inherent limitations of the system used  to make  the mea-
surements .  The usefulness of the measurement data is  dependent to some
extent upon the degree to which the magnitude of this  uncertainty is known
and upon its relative impact.  The TSDF testing described in this report
included a quality assurance/quality control (QA/QC) program.  The objec-
tives of the QA/QC efforts were twofold.  First, they  provided the mechanism
for controlling data quality within acceptable limits. Second, they form
the basis for estimates of uncertainty by providing the necessary informa-
tion for defining error limits associated with the measurement data.

     The quality control part of the QA/QC effort consisted of numerous
procedures designed to provide ongoing checks of the primary components of
the various measurement systems.  Examples of these procedures include
instrument calibration checks (single points) linearity checks (i.e., multi-
point calibrations), control standard analyses, blanks (see Appendix H) and
duplicate samples and analyses (see Appendix I).  These procedures, along
with required frequencies and acceptance criteria for  each QC check, are
described in detail in the Test Plan/Quality Assurance Project Plan prepared
for this field test.

     The evaluative part of the QA/QC effort was designed to provide a basis
for quantitative estimates of uncertainty in the measurement data.  Uncer-
                                                          »
tainty estimates for individual measurements, such as  the concentration of a
particular class of VOC compounds, for example, provided  the basis for
estimates of overall uncertainty in the approaches for measuring  emission
rates and/or concentrations.  Independent QA audits were  not performed as
                                    6-1

part of the sampling and analysis effort for this  site.  As such, no speci-
fic comments have been made concerning the accuracy of the measurements.
Recovery tests were run using methane for the flux chamber system.  The
average recovery for the flux chamber measurement  procedure was  95%.  This
is consistent with prior experience.  Those results are  included  in Appen-
dix G.  Appendix H presents blank values for both  the sampling and analyti-
cal systems.

     Uncertainty estimates should be viewed as the uncertainty involved in
making a single measurement.  As such, they can be compared to the overall
uncertainty of a group of field measurements to determine if the  variability
is predominantly due to the method or temporal/spatial fluctuations.  The
overall variability should be equal to or greater  than the estimated sam-
pling and analytical variability.  The degree to which it is greater indi-
cates the significance of temporal/spatial variations in the set  of field
measurement.

     The variability reported in this section has  been expressed  as a coef-
ficient of variation (C.V.) which is defined as:

                                      S
                               C.V. = x x 10°

where, S is the standard deviation and X is the mean of  the individual
measurements.

     The results presented in Section 2 include 95% confidence intervals for
mean emission rates and concentrations.  The 95% confidence interval is
estimated by:

                                 X +tS/
                                    6-2

-------
where, n is the number of measurements used to compute  the  average, X, and
standard deviation, S, and t is a tabled statistical  value  (0.025 confidence
level, n-1 degrees of freedom; when n is greater than 10, t approaches 2).

     A comparison can then be made between the estimate of  precision, C.V.,
and the 95% confidence interval where the 95% confidence interval is com-
puted using the C.V.:
                                    /C.V. x X\
                               x± t
6.1  MEASUREMENT VARIABILITY

     With any measurement effort, a primary data quality  consideration  is
measurement variability, or precision.  For this program, duplicate samples
and/or analyses were used to quantitate sampling and  analytical variability
for the various measurement parameters and techniques (see Appendix I).  In
order to increase the representativeness of these estimates of variability,
results for this site were pooled with the results from field tests per-
formed by the same field crew, with the same equipment and during  the same
time frame.  The resulting precision estimates  represent  the amount of
variability which was due to random error in the samp ling /analytical pro-
cess, independent of actual variability in the  parameter measured.

6.1.1  Flux Chamber Measurements

     Flux chambers were used to make direct emission  measurements  (see
Section 5.1.1).  Two sampling/analytical techniques were used in this mea-
surement approach.  One technique consisted of  collecting samples  in eva-
cuated stainless steel canisters which were then returned to Austin for GC
analysis.  The other technique involved collecting samples in a gas syringe
for on-site analysis by GC .  Duplicate flux chamber samples were collected
using both the canister (2 sets) and syringe (4 sets) sampling techniques.
                                    6-3

-------
Syringe samples collected during the program were  analyzed  in duplicate
(i.e., duplicate analyses of a single sample).   Results  for duplicate
analyses (32 sets) were used to estimate analytical precision for the on-
site GC analyses.  Results for duplicate samples (6 sets) were used to
estimate overall sampling and analytical variability  of  the VOC concentra-
tion measurements associated with the flux chamber technique.  Precision
estimates are summarized in Table 6-1.

     The precision estimates shown in Table 6-1  are expressed in terms of
pooled (i.e., "average") coefficients of variation for duplicate samples and
duplicate analyses.  The coefficient of variation  represents the standard
deviation of the measured values expressed as a  percentage of the mean.  Two
estimates are presented for each class of compounds.  One is for species in
each class (e.g., paraffin species), and represents the  pooled CV for indi-
vidual compounds in that class.  The other estimate represents the preci-
sion, or variability, for class totals (e.g., total paraffins).

     Similar estimates of precision for flux chamber  canister samples (4
sets) are also presented in Table 6-2.

     Additionally, an estimate of the emission rate variability was made
based on a Monte Carlo simulation.  Values were  input to the emission rate
equation using typical magnitudes and uncertainties.  Table 6-3 lists the
values assumed.  The values of the VOC concentrations and variabilities are
those listed above.  Two hundred trial calculations were made of the emis-
sion rate allowing the input values to vary within the assigned range.  The
calculated emission rates were then used to determine the uncertainty of the
measured emission rate.  These results are summarized in Tables 6-4 and 6-5
for flux chamber emission rates calculated using gas  syringe samples and gas
canister samples, respectively.

6.1.2  Liquid Concentration Measurements

     Liquid samples were obtained to determine  the concentration of volatile
species present in the ponds (see Section  5.3). The samples were obtined in
VGA vials and returned to Austin for analysis by GC, as with the canister
samples.  The results of duplicate analyses  (3  sets) from a single sample
were used to estimate the analytical precision. Results for analysis of
duplicate samples (2 sets) were used to estimate the sampling and analytical
variability of the liquid concentration measurements as a whole.  These
precision estimates are summarized in Table  6-6.

6.1.3  Soil Core Concentration Measurements

     Soil core samples were obtained to determine the concentration of
volatile species in the landfills (see Section  5.4).  The samples were
obtained using a thin walled tube sampler  which was capped on site and
returned to Austin for analysis by GC, as  with  the canister and liquid
samples.  The rersults of duplicate analyses  (4  sets) from a single sample
were used to estimate the analytical precision. Results for analysis of
duplicate samples (2 sets) were used to estimate the sampling and analytical
variability of the soil core concentration measurements as a whole.  These
precision estimates are summarized in Table  6-7.

6.2  GC-MS CONFIRMATION OF SELECTED CANISTER SAMPLES

     As part of the analytical quality control  for the project, several air
samples that had previously been analyzed  by GC-FID/PID/HECD were selected
for confirmation of compound identity by GC-MS. The results obtained from
the samples selected for confirmation are  presented in Table 6-8.  The GC-MS
analytical protocol used for the confirmation was designed to provide quali-
tative information on the major components observed in the samples.  The
sensitivity of the instrument and the sample size analyzed were selected
with this fact in mind.  The compounds which were  listed were not
