Mr. Underwood:
This Site Characterization Report (Report) and Remedial Action Plan (RAP)is submitted by Soils
Engineering, Inc. (SEI) following the completion of field activities and the receipt of analytical
test results at the Sandstone Education Center located at 300 E. Truxtun Avenue in Bakersfield,
CA. (site). SEI supervised the removal of 2 brick lined underground storage tanks, the
excavation· of hydrocarbon impacted soil, and advanced 7 soil borings to a depths ranging from
40" to 58' feet below ground surface in the area of the former underground storage tanks (UST's)
to collect soil samples for chemical analysis. This report describes the field work conducted,
an~ùytical results of soil samples, cross-sections of the identified oil impacted soil, conclusions and
recommendations for the site.
BACKGROUND
This is the location of the former Bakersfield Sandstone Brick Company, which operated from the
early 1900's to the 1930's. They produced bricks at this location, which included numerous
structures, a sand pit, retort burners, kilns, a lime shed, an oil pump, an oil tank and brick storage
areas. At the Kern County Main Library Sanborn Fire Insurance Maps for the years 1905, 1912
and 1949 were reviewed. The 1905 Sanborn Map shows the Bakersfield Sandstone Brick Co
with the following: a main building with retorts, brick press and office area. Smaller buildings
storing lime and cement. Northeast of main building is an area where a 600-gallon underground
oil storage tank is shown along with a 10" diameter well approximately 52' deep. Two (2) kiln
seats lie along the western border with Inyo St. and one (1) is west of the main building. A
tramway connects the brick retort with the kiln seat. The east side of Inyo Street was not
ma.pped. The 1912 Sanborn Map is similar to 1905 with a larger warehouse in southwest corner
of the site. Oil tunnels are now shown going from oil pump (where oil tank was) eastward and
southward. Eastside of Inyo St. and west of Tulare St. is brick storage yard in northwestern
portion and sand pit on eastern portion. A rock bin and underground tunnel are also shown.

An old building between the main Sandstone Building and the office buildings to the north was
recently demolished due to its unreinforced construction. During the removal of the foundation
of this old building 2 brick UST's were uncovered along with brick tunnels leading from them to
the east. The Bakersfield Fire Department was notified of the presence of the UST's, but removal
permits were not required. The BFD wanted to be informed on the results of the soil samples
collected beneath the UST's and the extent of contamination if present.
SCOPE OF WORK CONDUCTED
Removal of 2 Brick-lined UST's & Brick-lined Tunnel
On April 24 and 25, 2000 SEI supervised the removal of brick-lined Tank 1 (west) and Tank 2
(east) along with portions of brick-lined tunnels. Tank 1 was approximately 12' deep and 8'
diameter for an estimated capacity of 4,500 to 5,000 gallons. Tank 2 was similar in structure, but
slightly smaller and had a concrete cap approximately 5' below ground surface (bgs.) within the
ta.nk. Hydrocarbon stained soil was evident starting approximately 3' bgs. sloping down to
approximately 6' bgs. adjacent to Tank 1. In an effort to characterize the extent of oil-impacted
soil in the area of Tank 1 a backhoe was utilized to deepen and widen the excavation. Soil
samples were collected in brass sleeves on the west sidewall (Tl-W-lO'), the bottom at 16' (Tl-
BTM-16') and at the bottom at 23' (Tl-23'-BTM) from the backhoe bucket. The soil samples
were sealed with Teflon-lined caps, labeled and placed in an iced cooler. Hydrocarbon impacted
soil was still evident at the base of the excavation at 23' bgs. and at the west, south and east
sidewalls.
Tank 2 also had hydrocarbon impacted soil adjacent to and beneath the tank and soil samples T2-
15', T2S-5' and T2S-11' were collected to characterize this area and the adjacent tunnels.
Portions of a 6' diameter brick-lined tunnel (North Tunnel) proceeding approximately 65' east
from Tank 1 were removed revealing oil-stained soil beneath the tunnel. Soil samples were
collected along the north tunnel (TF-W-lO', NTN-N-14', and NTN-E-15') to characterize the oil-
impacted soil in this area. An additional 4' diameter brick-line tunnel (South Tunnel) was found
proceeding east from Tank 2 and also had oil-impacted soil beneath the tunnel floor. An
additional brick and concrete structure proceeded southerly from Tank 2 toward the Sandstone
Building Center with hydrocarbon impacted soil beneath. Portions of the excavation were
backfilled for safety and to prepare drilling pads for further characterization.
Drilling of 7 Soil Borings
SEI utilized an SEI owned and operated Hollow-stem auger drill rig to advance 7 soil borings to
depths ranging from 40' to 58' below ground surface (bgs) at locations shown on the attached
Plot Plan. Soil boring B-1 was placed near the center of former Tank 1 and drilled to a depth of
48' bgs.. Soil boring B-2 was placed approximately 50 feet east of B-1 in the area of the north
tUlnnel. Soil boring B-3 was placed approximately 40' east of B-2 near the eastern edge of the
former building. Soil boring B-4 was placed approximately 20 feet south of boring B-2 near

former Tank 2 and associated tunnels. Soil boring B-5 was located approximately 35' feet
northeast of B-1. Soil boring B-6 was placed approximately 30 feet southeast of B-4. Soil
boring B-7 was placed approximately 30' west of boring B-1. A geologist supervised by a
California registered geologist oversaw the drilling process. Soil samples were collected at 5 to
10 foot intervals and evaluated in the field for petroleum hydrocarbons (staining and odor), soil
type and photo-ionization detector (PID) readings. A soil sample from each sampling interval
was sealed, labeled and placed in an iced cooler. See Plate 2 for soil boring locations.
The augers were steamcleaned between borings and the sampling equipment decontaminated
between sampling intervals to prevent cross-contamination.
The soil borings were backfilled with bentonite chips (bottom 3') and soil cuttings up to the
surface. The soil cuttings were stockpiled and covered by plastic sheeting. Soil sample TI-Pro
was collected from the stockpiled cuttings and analyzed for profiling purposes prior to
disposal/recycling activities.
Analytical Testing
Selected soil samples from the excavation and soil borings were analyzed for Total Recoverable
Petroleum Hydrocarbons (TRPH), volatile organics (benzene, toluene, ethylbenzene, and total
xylenes (BTEX», and MTBE at State certified analytical laboratories. In addition soil sample
T2S-11 was analyzed for fuel fmgerprinting and sample TI-Pro was analyzed for CAM17 Metals,
and Chromium 6 for profiling purposes.
FINDINGS
SoH Characteristics
Soil encountered in the excavation and the 7 soil borings conducted at the site in general consisted
of silty sand (SM) and sandy silt (ML) to a depth of approximately 22' bgs., underlain by silty clay
(CL) to a depth of approximately 25' bgs.. Silty Sand (SM) and Sand (SW) was encountered
from 25' to approximately 33 feet bgs. where a clay (CL) or clayey silt (ML) was observed. From
40' bgs. to 55' silty sand (SM) and sand (SP) was encountered. A clay (CL) was encountered at
a depth of 55' in boring B-2.
Petroleum stained soil was encountered in the majority of the borings starting from 5' to 7' bgs.
except for borings B-5 and B-6 where minor staining started at 32' to 33' bgs.. Boring B-7 had
no petroleum staining or odor to a depth of 40' bgs.. Below a depth of 35' bgs. the petroleum
odor and staining (if present) decreased significantly. The highest PID reading (1800 ppm) was
recorded in boring B-2 at 28' bgs..
See attached Boring Logs in Appendix B for more detail.

Analytical Results of Soil Samples
The analytical results of the selected soil samples analyzed from the soil borings are presented on
Table 1. The analytical results indicate significant petroleum hydrocarbons are present from near
surface to approximately 35' bgs. in the area of soil borings B-1, B-2, and B-4. The highest
TRPH concentration reported was 40,000 ppm in soil sample T2S-11'. The highest benzene
concentration was reported in soil sample T2-15' (0.0146 ppm) with the majority of the soil
samples having no BTEX constituents reported. Soils samples TI-16' -BTM and TI-Pro had
elevated detection limits of 0.530 and 0.370 ppm for benzene and were reported as none detected
(ND). The fuel fmgerprint analysis of soil sample T2S-11' indicates that the main contaminant is
in a diesel range with gasoline and crude oil range hydrocarbons also reported. The
chromatogram indicates that this contaminate is closest to a bunker fuel or weathered crude oil.
Metal concentrations were in the normal range for the soil sample TI-Pro. The soil is classified
as a non-hazardous waste based on this analysis. See Table 1 and attached analytical reports in
Appendix A for more detail.
CONCLUSIONS
Based on field observations and soil sample analytical results SEI concludes the following:
1) Petroleum hydrocarbons are present in soil from near surface to approximately 35' feet bgs. in
the areas of Tank 1, Tank 2 and the north and south tunnels. Lateral extent of this
hydrocarbon impacted soil is approximately 15' west of Tank 1, 5' north of the north tunnel
excavation, 30' south of Tank 2 and approximately 90' east of Tank 1. The estimated area of
the petroleum hydrocarbon plume is approximately 110' in diameter east-west and
approximately 50' in diameter north-south to a depth of 35' bgs. which equals approximately
5600 cubic yards. See Plates 3A and 3B for hydrocarbon plume cross-sections.
2) The highest benzene concentration reported in the soil samples was 14.6 parts per billion
(ppb) at a depth of 15' in sample T2-15'. The majority of the soil samples had no BTEX
constituents reported.
3) The petroleum hydrocarbon plume is apparently bunker fuel or a weathered crude oil, with the
majority reported in the diesel fuel range in the fuel fmgerprint. The highest TRPH result was
40,000 ppm at 11' in sample T2S-11'. It appears that the hydrocarbons were stopped by a
Clay layer starting at a depth of approximately 32' to 33' in most of the borings.
4) No elevated concentrations of BTEX or metals were reported in the hydrocarbon impacted
soil sample (TI-Pro) collected from the stockpiled soil, indicating that the hydrocarbon
stained soil is a non-hazardous waste.
5) No significant petroleum hydrocarbons are present at borings B-3, B-5, B-6 or B-7 to the
total depth of the borings (40' to 55' bgs.).
6) Depth to groundwater in this area as reported by the Kern County Water Agency is
approximately 220' bgs. (October, 1998) or approximately 185' below the base of the
hydrocarbon plume.

7) The nearest public drinking water well (California Water Service well #98-01) is over 1000'
southeast (down-gradient) of the vadose plume area. Static water level at this well in March,
2000 was 221' bgs..
REMEDIAL AL TERNA TIVES
The following remedial alternatives are presented for the site.
Natural Attenuation
The petroleum hydrocarbon plume extends to a depth of approximately 35' bgs. in the area of the
former brick-lined UST's and tunnels. A good portion (approximately 1000 cubic yards) of the
hydrocarbon impacted soil has already been removed and stockpiled during the site
characterization phase of the project. With the depth of groundwater reported at 220' bgs., there
is approximately 185' of soil buffer zone between the base of the hydrocarbon plume and the
unconfmed aquifer beneath the site. It is highly unlikely that the petroleum hydrocarbon plume
will ever migrate to the groundwater. The nearest drinking water well (California Water Service
Station 98-01) to the plume area is over 1000' southeast (down-gradient) and completed in a
zone hundreds of feet deeper than the base of the plume. The source of the petroleum
hydrocarbon plume, the former UST's and associated oil-tunnels, have been removed and will not
continue to add to the plume. The levels of benzene are very low in the soil with the likely
elevated cancer risk to the on-site employees less than 1 x 106. If the petroleum hydrocarbons are
left in-place they will continue to bio-degrade over-time further reducing any current
environmental risks. The hydrocarbon plume does not appear to be a significant threat to the
groundwater beneath the site or to on-site workers.
A5 part of this remedial action alternative SEI recommends removing any remaining hydrocarbon
impacted soil within the plume area as shown on Plate 2 to a depth of approximately 12' bgs.
(equal to the base of Tank: 1) to provide a 12' buffer zone from the surface. Any "clean"
unstained soil overburden should be segregated from the stained soil and can be used as fill. After
removal of the stained soil to a depth of 12' bgs. the excavation should be backfilled and
compacted to a minimum of 90% relative density up to match existing grade minus pending
surface cover. An asphalt or concrete cover should be placed over the vadose zone plume area to
prevent water inftltration, minimize the potential for the hydrocarbon plume to migrate deeper and
for the prevention of the minor volatile organics in the soil to migrate to the surface. Cost for the
cap would range from $10,000 to $40,000 depending on the material used. The excavation,
transportation and disposaVrecycling of the hydrocarbon impacted soil is estimated at $35 per ton
plus backfill and compaction testing. An estimated 1000 cubic yards of hydrocarbon impacted soil
is left to be excavated with approximately 1000 cubic yards of hydrocarbon impacted soil
currently stockpiled. SEI recommends this remedial alternative since it is the most cost effective
and quickest alternative.

Excavation of Petroleum Hydrocarbon Plume .
The petroleum hydrocarbon plume extends to a depth of approximately 35 feet bgs. in the area of
the former UST's and tunnels and is in a confmed area between two (2) buildings on the north
and south. An excavation to a depth of 35' bgs. with a diameter of at least 60' in this area would
not be feasible. The stability of the two (2) building foundations would be compromised by an
excavation of this extent. Estimated cost for this type of excavation with extensive shoring of the
sidewalls on the north and south would be well over $200,000. Based on the above information
this remedial alternative is not recommended for this site.
In-Situ Bioremediation of Petroleum Hydrocarbons
The petroleum hydrocarbon plume at the site could be removed by the remedial alternative in-situ
bioremediation. This would involve the installation of multiple bio-vent wells (at least 15) to
depths of 35' within the plume area of soil borings B-1, B-2 and B-4. Since there is a great deal
of silt and clay within the plume it may be difficult to provide air and nutrients to the plume cost
effectively. A bio-venting pilot test would need to be performed on the bio-vent wells to
determine the effectiveness of in-situ bioremediation at this location and to determine the
appropriate flow rates, size and type of bio-venting unit. Microbe counts would need to be
evaluated to see what indigenous hydrocarbon degrading bacteria are present. Based on the high
TRPH values reported within the plume the levels may be too high for the bacteria to exist in high
numbers. If the pilot test shows that bio-venting would be effective at the site, an authority to
construct (ATC) permit would be acquired from the Kern County air pollution control district
(APCD). Once the ATC permit is approved, bio-venting piping connecting the wells to the bio-
venting system would be installed. Operation and maintenance of the bio-venting system would
be conducted for approximately 12 to 24 months. Test soil borings (at least 5 to 35' bgs.) would
be drilled periodically to collected soil samples for analysis to evaluate the reduction of the
petroleum hydrocarbons in the soil after bio-venting every 6 months or so. If the analytical results
indicate a significant reduction in petroleum hydrocarbons in the soil, closure of the site would be
recommended. Estimated cost for the installation and operation of a bio-venting system for a
period of up to 2 years would be $120,000 to $150,000. Based on the presence of less
permeable soils and possible low indigenous bacteria counts this remedial alternative is not
recommended.
RECOMMENDA TIONS
SEI recommends the implementation of the natural attenuation remedial alternative with the
removal of any remaining hydrocarbon impacted soil to a depth of 12' bgs. and the placement of
an asphalt or concrete cap over the in-place petroleum hydrocarbon vadose plume.
