SUBJECT: RECONNAISSANCE INVESTIGATION OF PESTICIDE
CONTAMINATION AT BAKERSFIELD AIRPARK
IT PROJECT NO. ME0183
Dear Mr. Oberho1zer:
Attached is our report on the Reconnaissance Investigation of Pesticide
Contamination at Bakersfield Airpark. The report describes the scope of our
investigation, analysis results of soil, water and airborne dust samples
recovered from the Airpark property, and our conclusions based on findings of
this preliminary study. We have also included recommendations for additional
work to more completely define the extent of soil contamination and to
investigate the potential for ground water degradation.
Although remediation of site contamination was not within our scope of work,
we have provided a brief discussion of some options which could be implemented
to reduce the potential hazard to surface receptors and the risk of polluting
ground water beneath the site. However, we wish to emphasize that it would be
both technically and financially prudent for the City to carefully coordinate
any future site investigation and remediation work with that performed at the
Garriott Crop Dusting Company property under the direction of the California
Department of Health Services and the Regional Water Quality Control Board.

1.0 INTRODUCTION
This report summarizes a reconnaissance investigation of potential soil and
surface water contamination of the Bakersfield City Airpark conducted by
International Technology Corporation (IT) for the City of Bakersfield (the
City).
The report reviews sampling and analysis methodologies, discusses
findings of the investigation, outlines some basic remediation measures that
may be undertaken, and provides recommendations for further study to better
define the extent of contamination.
The reconnaissance investigation
indicated the presence of several contaminants, principally pesticides and
herbicides, in the shallow soils and surface water on City owned property.
These contaminants were, most likely, transported by overland and channelized
flow of surface water from the adjacent Garriott Crop Dusting Company
(Garriott) property.
1.1 PROJECT BACKGROUND
The Bakersfield Airpark, owned by the City of Bakersfield, is located on South
Union Avenue in the southeastern portion of the City (Figure 1). The Garriott
Crop Dusting Company is located on private property adjacent to the southern
boundary of the Airpark. Unlined earthen pits located on the Garriott prop-
erty, reportedly containing pesticide and other chemical residues, may cause
soil and water contamination in the area. State and county officials are
:1 currently conducting an investigation of the Garriott site. (See: Notice of
Violation and Schedule for Compliance issued to Garriott by the State of
California Department of Health Services (DHS) reproduced in Appendix A). The

e
Garriott faci 1 ity onto City property, requested IT to inspect the Airpark
property for potent i a 1 pest i ci de contami nat i on on Ci ty owned 1 and. IT was
asked to recommend a preliminary program of soil, water and air sampling to
assess the extent of contamination, if present, and to evaluate an area for
possible enclosure by a fence to secure from innocent trespassers any portion
of City property suspected of being contaminated.
The initial site inspection was performed under a Master Services Agreement
(No. 86-73) between the City and IT made on 7th May 1986 which provides the
general terms and conditions for ITI s provision of services to the City.
Following inspection of the site, IT recommended the program of prel iminary
investigations described in this report. The work was authorized by the City
on July 9th, 1986 and also performed under the terms of the Master Services
Agreement.
1.1.1 Initial Site Inspection
On the evening of July 1st, 1986, Mr. Duane Meadows (Field Chemist), with Mr.
Eric Paukstaitis (Senior Project Hydrogeologist), Mr. Robin Hamlet (Project
Geologist) and Dr. Dai Watkins (Manager, Geosciences) of IT IS staff, visited
the Airpark to make a reconnaissance inspection of conditions at the site.
Throughout the site investigation, ITI s staff wore protective clothing con-
sisting of disposable white Tyvek coveralls with boot covers. Without leaving
City property, they observed the general state of the terrain, man-made struc-
tures and parked aircraft at the Garriott facility and adjacent areas. The
principal fences, paved areas, ditches, drains, and water sump in the area are
shown on Figure 2 which is a sketch map prepared from notes taken at the time
1-2
..3:0981/09186
e
.
of the visit. This sketch is not intended to be definitive or complete with
respect to any of the features shown. It is intended only as an aid to this
presentation. Property bounderies, and their relationship to fence lines,
were not determi ned duri ng IT IS site inspection. Such determi nat ions are
beyond the scope of this report.
IT staff observed that the area between the Garriott facility and the Airpark
runway shows evidence of surface water runoff flowing from the crop dusting
station onto City property. Further, discoloration of low lying areas
suggested that water may have ponded and contamination of surficial soils may
have occurred. A container cap, marked with the name of an industrial company
known to manufacture pesticides, was seen (but not removed) within the
inspected area on City property. Disturbed ground at one location suggested
the presence of a backfilled trench or sump extending under the existing fence
that separates the Garriott facility from the Airpark.
,~
An unlined surface water sump is present on City land south of the Garriott
facility. The purpose of the sump is to collect excess runoff during periods
of high rainfall. This sump receives water via a buried 14-inch diameter
culvert that has its head on City property immediately east of the Garriott
facility. A shallow, concrete-lined drainage ditch leads into the culvert.
This ditch crosses the Garriott property and is a conduit for surface water
drainage from south Union Street, west of the Airpark. The ditch can also
pick up water flowing over the ground adjacent to it, including water flowing
from the Garriott property.

e
e
ITls staff noted that the area inspected is covered with dust, (to a depth of
several inches at some locations). This dust has the potential to be blown
into the air by wind and especially by propeller wash from hel icopters and
fixed wing aircraft operating from the Garriott facility and the Airpark.
These observations were the basis for our recommending the air monitoring
program described in Section 2.3 below.
Based on their observations, IT's staff delineated an area of City property
within which there was sufficient prima facie evidence of soil contamination
to warrant further study. Thi s area is shown on Figure 2 and is bounded by
the main runway, the taxiway to the Garriott facility and the fence along the
east side of the Garriott facility.
1.1.2 Fenci ng
....'}-
As requested by the City, and based on observations made during the initial
site inspection, IT recommended lines for a fence that would enclose areas of
suspected contamination. This area coincides with the "Study Area" shown in
Figure 2. However, subsequent review of Federal Aviation Administration (FAA)
regulations revealed that stationary structures, including fencing, can not be
erected within 75 feet of an active runway. Complying with the regulations
would reduce the fenced area to some 25% of that included within the study
area (shown in Figure 2). Given these restrictions, and recognizing that the
area of concern is not open to public access, it was determined that erection
of a fence would have little merit. Thus, fencing was excluded from the work
order issued to IT by the City. The City has erected signs and ribbons around
the area to warn trespassers that the area is contaminated.

2.0 SOIL, SURFACE WATER AND AIR SAMPLING PROGRAM
Soil and water sampling at the site was initiated on July 11, 1986 and com-
pleted on July 15th. Air monitoring was performed on the 15th of July and
repeated on Augu st 8th. A 11 samp 1 i ng was performed by personne 1 equ i pped
according to U.S. Environmental Protection Agency (EPA) Protection Level C
including; white Tyvek coveralls, disposable latex gloves and boots, and air
purifying respirators fitted with organic vapor cartridges. A decontamination
stat i on was estab 1 i shed pri or to each day IS samp 1 i n9. Complete decontam-
ination of equipment and personnel was conducted prior to egress from the site
to prevent transport of contaminated materials to uncontaminated areas.
2.1 SOIL SAMPLING
Soil samples were obtained from 12 sites on the Airpark property at the
locations shown on Figure 2. Preliminary sample locations were selected based
on observations made during the site reconnaissance on July I, 1986. Some
minor changes in sampling locations were made in the field by IT's geologist
in charge of the sampling program.
Samples were obtained using a 3-inch diameter hand auger equipped with a
polyvinyl chloride (PVC) tube liner. At each sampling location, auger cores
were obtained every 6 inches from the surface to a depth of 2 feet except at
'.'
.¡
.::¡
..
locations where the subsurface conditions were unsuitable.
Samples were
transported under strict Chain-of-Custody procedures to IT's laboratory in
Santa Clara, California for analysis.

e
e
Following completion of sampling at each location, the auger and PVC liner
were throughly cleaned and decontaminated by washing with Trisodium Phosphate
(TSP) and rinsing with distilled water to ensure that no cross-contamination
occurred between samples.
Sample locations S2, S6, S8 and 511 are in topographically low areas presumed
to be inundated by surface water runoff and/or ponding during wet weather. It
was suspected that overland and channelized flow from the Garriott facility
would collect in these areas and concentrate transported contaminants in the
soils. 5ample location 53 was on a topographic high in the middle of the
suspected ponding area.
Locations 51, 54, and 55 are along the taxiway from the Garriott facility to
the main runway. It was speculated that, over time, leakage from planes using
the taxiway could concentrate contaminants along this zone. At sample loca-
tion S5, an accumulation of trash was found 6 inches below the surface. Arti-
facts uncovered included: a plastic bottle of motor oil, a beer bottle, and a
decomposed, plastic-lined, 50-pound sack containing an unidentified powder.
This debris was localized and similar materials were not found at the near-by
Sampling Locations 51, S2 and 54.
At location 57, a sediment sample was taken at a six-inch depth from the paved
ditch which carries water to the culvert on Airpark property. Stains in the
paved drainage ditch on Garriott property suggest that at some time in the
past chemicals may have drained into the ditch.

e
Samp 1 e 1 ocat ions S9 and S 10 are in what appears to be a backf ill ed earthen
ditch extending from the Garriott property onto the Airpark site.
Sample location S12 is on the bank of the surface water sump located on City
property to the south of the Garriott facility.
2.2 SURFACE WATER SAMPLING
A sample of the water (Sample No. WI) in the surface water sump was obtained
and shipped to IT1 s laboratory under Chain-of-Custody control for analysis.
It was observed during sampling that vegetation along the edge of the sump was
dead; however, evidence of insect life was noted in the water.
The culvert originating at the paved channel that passes through the Garriott
facility onto City property (see Figure 2) was assumed to discharge to the
sump. However, no evidence of the culvert outlet was observed during
sampling. Subsequent inquires at the City Engineer1s office indicate that the
culvert enters the sump below the water surface.
2.3 AIR MONITORING PROGRAM
\
Air monitoring was conducted on the Airpark property on July 15, 1986. Loca-
tions of the air monitor stations are shown on Figure 3. Sampling locations
were divided ,into two groupings. Group A were locations arranged along the
fence separating the Garriott facility from City property and in areas
generally adjacent to Garriott's property. Group B locations were generally
remote from the Garriott facility including locations on the periphery of the
2-3
';:0981/09186
e
e
Airpark. Two sampling shifts were used to obtain 16 samples. Airborne
particulate samples were collected using Gillian air pumps to draw air through
0.3 micron pore glass fiber filters. Two air pumps were used at each location
so that one filter would be available for analysis for Organochlorine and PCB
group contaminants and the second for analysis for Organophosphorus group
contaminants. Winds were variable in both direction and velocity during the
sampling on July 15. It should also be noted that, during the air sampling
conducted on July 15, plane engines were tested on the Garriott property.
Reving of engines downwind of monitor locations A5 and A6 resulted in a
greater than normal volume of wind-blown particulates.
Due to an oversight at the laboratory, the complete suit of analyses that were
to be performed on the filters recovered from the air pumps on the July 15 was
not made. Consequently the air sampl ing program was repeated on August 8th.
The sample locations and procedures for the sampling were the same as for that
conducted on July 15.

3.0 SAMPLE ANALYSES
Soil, water, and air particulate samples obtained from the Airpark were
shipped under strict chain-of-custody procedures, to IT's Stoner Lab in Santa
Clara, California for analysis. Samples were tested for the suit of organo-
chlorine and organophosphorus pesticides and polychlorinated biphenyls (PCBs)
shown in Table 1.
Soil samples were composited in the laboratory. Using this method, half of
each of the soi 1 specimens recovered at various depths at a given sampl ing
location were combined and throughly mixed. The unused half of each specimen
has been archived at ITls laboratory. Thus the analytic results indicate the
presence at a part i cu 1 ar samp 1 i ng 1 ocat i on of any compounds detected in the
composited sample but do not provide information regarding the depth
distribution of contaminants. This method is appropriate for reconnaissance
investigations because it reduces analytical costs to a minimum, but at the
same time retains sufficient material for additional future analysis should
this be necessary.
The method of analysis for organochlorine pesticides, PCBs and organophos-
phorus pesticides in soil is adapted from E.P.A. Methods 3550, 8080, and
8140. The method of analysis for organochlorine pesticides, PCBs, and organo-
phosphorus pesticides in water is adapted from E.P.A. Methods 608 and 622.
:.,..
All soil and water samples were serially extracted with dichloromethane. The
"
dichloromethane extract was evaporated and the solvent exchanged to acetone.
For organoch 1 ori ne pest i ci des an a 1 i quot of the acetone extract was further
3-1
.3:0981/09186
e
e
concentrated and analyzed by gas chromatograph using a flameless alkali salt
nitrogen-phosphorus detector.
Filter disks from air monitoring stations were also analyzed for organo-
chlorine, PCBs and organophosphorus pesticides. The methods of analyzing
filter disks are taken from the NIOSH Manual of Analytical Methods. Samples
for analysis of organochlorine pesticides and PCBs are extracted by shaking
filter disks with iso-octane. An aliquot of the iso-octane extract was then
concentrated to a suitable final volume and analyzed by gas chromatography
using an electron capture detector. Samples for analysis of organophosphorus
pesticides are extracted by shaking filter disks with toluene. An aliquot of
the toluene extract was then concentrated to a suitable final volume for
analysis by gas chromatography using a flameless alkali salt nitrogen-
phosphorus detector.
Compounds included in the analysis scans (See Table 1) would have been
detected if present at or above the detection 1 imit. Detection 1 imits vary
from compound to compound depending on instrument sensitivity, and may also
vary from sample to sample depending on sample matrix. The detection limits
are given in Appendix B.

4.0 FINDINGS
The results of the analyses of the soil, surface water and airborne particu-
late matter samples are presented in Appendix B.
4.1 CONTAMINANTS IN SOILS
Of the 54 compounds in the analysis scan, 16 were found in the soil samples.
However, not all compounds detected were present at each samp 1 i ng 1 ocat i on.
The distribution of contaminants by sampling location is shown in Table 2.
Although contamination was found in the soil at all sample locations, the
highest concentrations and greatest numbers of contaminants are present within
and IIdownstreamll of the backfi lled trench that cross under the fence between
the Garriott facility and the Airpark (see Figure 2). Contaminants were found
at or near detection limits in soils along the edge of the taxiway from the
Garriott facility.
Dacthal, a selective pre-emergence herbicide, is the most widely distributed
and highly concentrated soil contaminant at the site and this may be used as a
tracer to provide a general indication of the distribution of contamination in
the study area. The distribution of concentrations of Dacthal is shown in
Figure 4. The pattern of distribution confirms our observations and
interpretations regarding the potential distribution of contaminants made
"
during the initial site inspection on July 1st, 1986.

Table 3 presents an analysis of soil contaminant distribution based on the
number of locations at which each compound was detected, range of concen-
tration found, and sample location of highest concentration of each contam-
inant. For comparative purposes, Table 3 also includes a listing of EPA
Maximum Contaminant Levels (MCL), California Department of Hea lth Services
(DHS) State Action Levels (SAL) and EPA or National Academy of Sciences
Suggested Non-Adverse Response Levels (SNARL) from Appendi x IV of Marshack
(1985) (See Reference 1). Designated Levels of contaminants for soils, from
the same source, are also listed in Table 3. It should be noted that the
Designated Levels do not take into account site specific conditions or the
cumulative effects of several constituents present in the soil. It should
also be understood that the presence of contaminants in soils on City property
does not provide definitive evidence of extant ground water contamination, nor
does it provide evidence of a quantifiable threat of future ground water
pollution. Such determinations would require a comprehensive geotechnical and
hydrologic study and are beyond the scope of work of this present study.
The values provided in Table 3 can not be used as definitive indicators of the
toxicity of contaminated soil to surface receptors. Guidance with respect to
the factors should be obtained from State and local Public Health agencies.
For information purposes, technical descriptions of the uses and
characteristics of the compounds found in the soils are provided in Appendix
C.

4.2 CONTAMINANTS IN SURFACE WATER
Only Dacthal (0.2 micrograms per liter) was detected in the water sample (WI)
obtained from the surface water sump. Higher concentrations of contaminants
were expected in the sump water because the culvert which drains into the sump
is suspected to act as a conduit for contaminant transport from the Garriott
property and adjacent areas of the Airpark. However, we understand that
sediments are periodically removed from the bottom of the sump. Such
maintenance would have reduced contaminant accumulation and thus mitigate any
potential for the sump to act as a vehicle for migration of contaminants.
Despite the low level of contamination detected in the sump during the
reconnaissance investigation, it would be prudent to perform additional checks
of water and sludges at this location to more fully evaluate the extent to
which it may be polluted. Recommendations for further investigation in this
area are discussed in Section 6.0.
4.3 CONTAMINATED PARTICULATES IN THE AIR
'..
Two contaminants were found in samples of airborne particulates from the
site. Dacthal was present in sampling filters at Stations A3, A4, A7 and A8
(July 15, 1986 sampling) in the amount of 0.01 grams per sampling location.
This is close to the detection limit of the analysis method used. These
sampling stations are all along, or close to the fence, separating the
Garriott facility from the Airpark. In the August 8th sampling 0.01 grams of
Dacthal was found in filters from sampling Stations A3 and AS. Filters from
Stat i on B7 located south of the ground water sump contained 0.13 grams of
Dacthal and 0.02 grams of Balan (also known as Treflan).

5.0 CONCLUSIONS
The preliminary investigation of City property adjacent to the Garriott Crop
Ousting facility has shown that soils and, to a lesser extent, surface water
at the site are contaminated by various pesticides and herbicides. It has not
been determined to what depth these contaminants have penetrated the soil and
whether they have reached the ground water system. The 1 i ke ly source of
contamination is the Garriott Crop Dusting facility. Contaminants have
probably been transported onto City property by overland and channelized flow
of surface water. A backfi 11 ed trench extendi ng from the Garri ott facil i ty
onto City property appears to be a primary source and/or route of contamin-
ation. The paved drainage ditch and buried culvert system also appear to be a
potential conduit for contaminant transport.
Evaluation of the public health consequences of the contamination detected at
the Airpark is beyond the scope of this report. Such evaluations fall within
the jurisdiction of the State and local Public Health authorities. Final
I
I
determination of the action, if any. required to remove any threat to the
ground water will be made DY the Regional Water Quality Control Board.
However, we offer the following evaluations, which are based on our general
experi ence, as an aid
to an appreciation of the risk potential po~
contamination.
The relatively minor quantities of contaminants detected in the air quality
samp 1 es suggest that dust blown from the site is not a threat to the 1 oca 1
population.

.
Some of the contaminants found in the soils at the site (e.g. Parathion
4 c.. .,,µ
(Ethyl), Endosu1fan I and II and Ethion) can be1 toxic to human receptors at
high concentrations, particularly through ingestion and absorption through the
skin. However, long term effects of chronic exposure at the
'---'," ""-
f~_~~n C¿,~2roperty are_ un~no;n. \\
_' __ ~ --tJ
The health risk to the general population in the neighborhood of the Airpark
from exposure to the contaminated soils is limited by the isolated nature of
the affected area. Located within the confines of the Airpark perimeter and
adjacent to the main runway, the contaminated area is not accessible to the
public except by trespassers. Some contaminants found at the site (e.g. DOT,
ODE, Methoxyc lor, Heptach 1 or, and Ch 1 ordane) may pose a threat to the 1 oca 1
ground water system, due in part, to their persistence in the environment.
Dactha1, although found at relatively high concentrations at the site, is not
generally considered a major threat to either humans or the environment. PCB
1254, at the very low concentration (0.2 ppm) found at a single sampling
location (52), is not considered to be a significant threat to humans or the
environment. Potential sources of PCB in the soil include possible historical
use of PCB oils as an adjuvent in pesticide formulation or its use in
hydraulic line fluid.

6.0 RECOMMENDATIONS
The preliminary investigation of the area adjacent to the Garriott Crop
Dusting facility has identified contamination on City property. Additional
study of the site will be required to better define the areal and vertical
distribution of contamination and to provide a basis· for any remedial or
corrective action that may be required. Should the City decide to proceed
with additional investigations, independent of those that are expected to be
required of Garriott by the regulatory authorities. the work described below
is recol11TTlended.
6.1 ADDITIONAL SOILS INVESTIGATIONS
Analyses of selected archived soil samples. obtained from areas of highest
contami nant concentrations. shou 1 d be performed to defi ne deptn of contami n-
ation. Additional sampling should also be undertaken. A shallow soil sample
(to 2 feet) should be obtained in the area southeast of sample location 511 to
ensure that s i gnif i cant contami nat i on does not extend in th is direct ion. A
drilling rig should be mobilized to obtain soil samples to a depth of 30 feet
II in the vicinity of sample locations 510. 511. and 58. These holes can be
I drilled using a small hollow-stem auger rig and split-spoon sampler. Results
of soil analyses from these holes would be used to determine required depth of
soil excavation.

6.2 HYDROGEOLOGIC INVESTIGATION
6.2.1 Additional Investigations in the Surface Water Sump
, A 1 though only minor traces of one contaminant (Dacthal) were found in the
surface water sump on City property, and no contami nants were found in the
soil sample form the banks of the sump, we recommend additional sampling of
the water and sump-bottom sludges. This will be particularily important if
closure and backfilling of the sump is contemplated.
Three additional samples of the shallow soil from the banks of the sump close
to the water line should be obtained for analysis. A second water sample
should also be obtained to confirm the results from the sample gathered
previously. Because pond-bottom detritus may retain residual contaminants, a
representative sample of the sludges should be taken. Twó samples are
recommended: one from near the outfa 11 of the cul vert and one from the
deepest part of the sump (presumed to be at the center). Th i s work wi 11
require a means of operating sampl in9 equipment over water. At present we
envision this being done using a small boat or raft. However, safety
considerations, as determined by a feasibility study, may require mobilization
of hydraulically operated personnel platforms or similar equipment.
Estimated Cost:
$8,500.00-$10,500.00
6.2.2 Ground Water Investigations
If the sludges in the surface water sump show evidence of significant
contamination, there would be sufficient prima facie evidence of potential
6-2
,:;:0981/09186
tit
e
ground water pollution via this pathway to justify a more complete ground
water investigation. It would be advisable to conduct this study in
conjunction with studies of the potential threat of ground water pollution
that is represented by the contami nated soil s on the Garri ott property and
adjacent thereto.
Preliminary to a ground water study, a review of city records and engineering
drawings should be undertaken to provide information on historical land use on
the City, Garriott and adjacent properties. If adequate records are not
currently available, a topographic survey, including elevation contouring,
shou 1 d be made of the Airpark and surround i ng property. Th is survey shou 1 d
include determination of land ownership. This could provide information
concerning past sources or routes of migration of contaminants.
A minimum of three boreholes should be drilled on City property to a depth
be low the water table and be comp 1 eted as monitor wells. At 1 east one of
these wells should be drilled in the vicinity of the sump. Soil samples would
be obtained during drilling and analyzed for those contaminants previously
found at the site. Ground water samples would be obtained from the wells and
analyzed for those contaminants found at the surface. Water levels taken in
the wells would be used to prepare a potentiometric surface map for estimation
of direction and velocity of ground water and potential contaminant flow.
Appropriate ancillary studies, such as determination of depth to water and
sampling in any existing wells in the near vicinity of the contaminated area,
would be included in the work.
Estimated Cost:
$75,000-$85,000

6.3 REMEDIATION MEASURES
Remediation of the contaminated area of the City property can not be
rationally considered in isolation from the remediation work that will be
required on the Garriott property. The principal reason is that as long as an
untreated source of contami nat ion, in the form of polluted water or soil,
remains on the Garriott property, pollutants can be transported by flow of
surficial or subterrainian water onto City property. Further, any remediation
work that may be undertaken on City property is 1 i ke ly to be under the
jurisdiction of the California Department of Public Health, the Regional Water
Quality Control Board and/or the Kern County Health Department. The
remediation procedures that they will require can not be predetermined without
a complete investigation of the Garriott property and the affected portion of
the City property taken as a who 1 e. However, we have out 1 i ned be 1 ow some
remediation measures that may ameliorate conditions at the site and that the
City may wish to undertake using its own resources or in cooperation with
Garriott. If such is the case, it would be advisable to consult with the
appropriate regulatory authorities before proceeding.
6.3.1 Diversion and/or Piping of Storm Water Drainage
The drainage ditch that carries storm water from Union Avenue through the
Garriott property onto the Airpark and, via the culvert described in Section
1.1.1, into the surface water sump, is a potential path for the transport of
contaminants. This mechanism for spread of pollution could be eliminated by:
1) complete diversion of the storm drainage from Union Avenue and other
-..'
6-4
0981/09186
e
e
tributary areas to an alternate outfall; thus permitting excavation and
removal of the existing drainage ditch and culvert or, 2) piping the surface
water sewer throughout its length to prevent inflow of surface contaminants.
If closure and filling of the surface water sump on City property is included
in this work, it should not be performed before the degree of contamination of
sludges or soils within the sump has been more fully evaluated.
6.3.2 Water Manaqement on the Garriott Property
Based on ITls observations during the site inspection on July 1st, it appears
that several interim measures cou 1 d be taken to reduce the ri sk of ongoi ng
contaminant migration from the Garriott property. Regrading and sealing the
ground could reduce the flow of storm water onto the Airpark and control the
rate of percolation into the contaminated soil. Construction of' an impervious
berm on the property line between the Garriott facility and the Airpark would
prevent runoff onto City property. However, this construction would need to
----
be--engineered such as to control ponding and in such a manner as to provide
for appropriate disposal of potentially contaminated water.
Removal of
standing water from ponds on Garriott property would eliminate this source of
contaminants. If ponds are dried, measures to control dust on the Garriott
----
property will be an important part of any work performed.
6.3.3
Isolation, Removal and/or Treatment of Contaminated Soils on Airpark
Property
-
As discussed previously, a comprehensive analysis of the remediation measures
that may be applicable to the contamination at the site will require a
6-5
.;3: 0981/09186
e
.
complete geotechnical and hydrologic investigation and guidance by the
concerned regulatory authorities. However, as an aid to a preliminary assess-
ment of the range of policy options that may be available, we have outlined
below three possible approaches to treatment of the contaminated soils on City
property.
The cost estimates cited are conceptual and should not be
considered as definitive.
OPTION 1: Paving of Site (No Contaminant Removal)
This alternative involves minimal grading prior to sealing of the site.
Except for nominal quantities associated with the grading, no contaminated
soil would be removed from the site. The site would be contoured to promote
runoff from the area. The entire area would then be covered with a seal
composed of impervious geotextile and an asphalt surfacing. Thé asphalt cover
-------
would eliminate wind blown dust and greatly reduce surface water recharge to
-
thearea.-- -- The reduced recharge would slow potentially leaching of soil
contaminants to the ground water system. However, since the potential source
of contami nat ion wou 1 d not be removed, the poss i bil i ty remains for eventual
ground water degradation.
OPTION 2: Selected Contaminant Removal/Sealing of the Site
This alternative includes removal of the most contaminated soils from the
site, replacement with clean fill, grading of the site, and sealing as for
.,
Option 1.
This would not only eliminate wind blown dust but would also
greatly reduce the long term potential for of ground water pollution.
..:
6-6
.,:G:0981/09186
e
e
OPTION 3: Contaminant Removal
This alternative would remove contaminated soils from the affected area to a
depth of up to two feet. Actual depth and area of excavation would depend on
extent of contamination a's determined by sampling and laboratory analyses.
Contaminated soils would be replaced with clean fill. If contaminants
remained below the depth of excavation the site would be sealed to prevent
leaching of contaminants to the ground water system.
Other remediation options (e.g. low temperature thermal desorption or
isolation of the contaminated soil by a clay-slurry cut-off wall) may be
available but their efficacy can not be assessed without comprehensive
geochemical and hydrologic studies.

samples for analyses.
The method of analysis for orqanochlorine pesti~ides, PCBs and
organophosphorus pesticides in seil is adapted trom t.P.A. Methods
3550, 8080 and 3140.
Thë method of analysis for orqanochlorine pesti:idçs, PCBs and
cr~anophospborus pesticides 10 ~ater is adapted frem E.P.A. Methods
0503 and 622.
~ll samples are serially extracted ~ith ¿i:hloroœethane. The
dichlercmethans ç~tract is a~apcr~ted and the sol~ent is exchan~ed t:
acetone. For orq3nochlorine pesticiàes and PCBs an aliquot ot the
acetone extract is excbanqed to hexane, cleaned-up throu;h Florisil and
analy~ed by gas chromatoqraphy (GC) usin~ an elactron =~pture åetectcr.
For organophosphorus pesticidBs an ali~uot of the acetone extract is
further concentrated and analï=ad by GC usinq a flamcl~s~ alkali ~alt
nitrogen-phosphorus ùetector.
.
Filter disks ~ere also analyzed for organochlorine, PCBs and
orqanopbosphorus pesticides. Each filt~r cassette contained two (2ì
filter disks. Beth disks in each cassette were combined fer the
extraction and analysis.

P:¡ge :
~he aethod ot analysis fer organochlorine pesticides and PCBs is
taken fro. the NrOSH Manual ot Analytical Methods. Samples are extracted
by shaking witb iso-octane. An aliquot of tbe iso-octane extract is then
concentrated to a suitable final volume Ind analy:ed by ~~S =hromatoqra~hy
using an electrcn capture ~etectcr.
The method of analysis for orqanophosphorus pesticides is taken
from tbe NIOSS Manual of Analytical Methods. Samples are extracted by
shaking with t~luene. An !liquot of the toluene extract is then :on-
côntrated to a 3uitatle final 70lume for analysis by ças chromatography
using a flameles! alkali salt nitrogen-phosphorus detector.
Any of the compounds in the Table ~f Results ~ould ha76 ~e2n

Organochlorine Pesticides and PCB 's,
Organophosphate Pesticides
Each filter cassetta contained two (2) filter disks. Both disks
in each cassette were combined fer the extraction and analysis.
The methcd of analysis for organochlorine pesticides and P~Bs is
taken troll the KIOSH Manual ot Analytical Methods. Samples-'ue
extracted by shaking with iso-octane. An aliquot of the iso-octane
extract is then concentrated to a suitable final voluae and analyzed
by gas chro.atography using an electron capture detector.
The method of analysis for organophosphorus pesticides is taken
from the NIOSH Manual of Analytical Methods. Samples are extracted
by shaking with toluene. An aliquot ~f the toluene extract is then
concentrated to a suitable final ~clume for analysis by gas chromo-
tography using a tlaaelass alkali salt nitroqen-phosphorus detector.
Any of the co.pounds in the Table of Results would have been
detected had it been present at or above the limit ot detection
listed. Detection limits vary from compound to co.pound depending on
instruaent sensitivity I and they may also 7ary from sample depending
on s&Aple matrix.
