1.0 INTRODUCTION
1.1 Scope and Purpose
Professional Service Industries, Inc. (PSI) was contracted by Unocal
Environmental Remediation Services (Unocal) to conduct verification soil sampling
at the former Unocal Service Station No. 7048, 2518 White Lane, Bakersfield,
California (Figure 1). Verification soil sampling was performed to determine the
effectiveness of site remediation activities completed using Soil Vapor Extraction
(SVE) with granular activated carbon (GAC) to remove volatile organic compounds
(VOCs) associated with a former gasoline and diesel release at the site.
This report presents documentation of remediation and verification soil sampling
activities conducted at the site. All work was completed in accordance with the
City of Bakersfield Fire Department (BFD) requirements and PSI's Workplan for
Verification Sampling and Site Closure Reporting, dated October 11, 1996,
1.2 Background
The former service station was decommissioned in early 1992 and the
underground storage tanks (USTs), product lines, and dispensers were removed
in September 1992 (GeoResearch, 1993a). The site is presently fenced and
unoccupied. A Phase II site investigation was conducted at the site in August
1993. The investigation identified concentrations of total petroleum hydrocarbons
as diesel (TPH-D) as high as 12,000 milligrams per kilogram (mglkg) beneath
dispenser Island 3 at 8 feet below ground surface (bgs). Total petroleum
hydrocarbons as gasoline (TPH-G) appear to have been limited to beneath
dispenser Island 1 primarily to depths of no more than approximately 40 feet bgs,
at which depth concentrations of 5,400 mglkg were identified. Traces of benzene,
toluene, ethyl benzene, and total xylenes (BTEX) were detected to approximately
48 feet bgs. A soil boring drilled fn the former UST pit encountered fill soils from
the UST removal activities to a depth of 28 feet. Analysis of the 30-foot sample
revealed a TPH-D concentration of 350 mglkg. Only trace concentrations of
toluene, ethylbenzene, and total xylenes were detected below a depth of 30 feet
beneath the former tanks.
SVE was used to remove VOCs from soil impacted by TPH-G beneath Island 1.
This included the removal of the VOCs by mechanically drawing or venting air
through the soil matrix. Carbon adsorption was used to treat vapors extracted
from the soil. Vapor extraction (bioventing) was also implemented to stimulate
bioremediation of TPH-D-affected soil beneath dispenser Island 3 by inducing the
flow of air through the affected soil matrix.

The soil vapor extraction system (SVES) was installed at the site in August 1995.
Operation of the SVES commenced in October 1995 and was completed in July
1996.
2.0 GEOLOGY AND HYDROGEOLOGY
The site is in the Great Valley geomorphic province, a long structural trough
situated between the Sierra Nevada to the east, the Coast Range to the west and
the Tehachapi Mountains to the south. In the Bakersfield area, the sediments
consist of recent and older alluvium derived primarily from the Sierra Nevada and
nearby Tehachapi Mountains, The older (Pleistocene) alluvium uncomformably
overlies Pliocene-Pleistocene continental clastic deposits, which in turn overlay
Tertiary and Cretaceous continental and marine clastic deposits (Muir, 1977). The
valley basement, consisting of pre-Tertiary granitic and metamorphic rocks,
underlies the clastic section at a depth in excess of 2,000 feet below ground
surface (bgs). Soils beneath the site consist of silty sand underlain by a section of
relatively massive unconsolidated fine- to coarse-grained sand to approximately
50 feet bgs.
In the Bakersfield area, groundwater occurs primarily under unconfined and
semi-confined conditions. Review of the Kern County Water Agency (KCWA)
map entitled "Groundwater Surface Elevation Map, January 1993," shows a
groundwater elevation contour at 200 feet above mean sea level (msl) in the
vicinity of the site. Review of the 7,5 minute Gosford topographic map
(photorevised 1974) indicates and elevation of the site at approximately 375 feet
msl. Comparison of the two elevations indicates that groundwater in the vicinity
should occur approximately 175 feet below existing grade with a southwesterly
flow direction.
3.0 SOIL REMEDIATION SYSTEM
The SVE system consisted of four vapor wells, one bioventing well, and one
background well. Operation of the SVES began in October 1995 and continued
through June 1996, at which time the system was permanently shut down. In
August 1996, all vapor extraction equipment was removed from the site except
for the vapor wells and conveyance piping.

4.0 SITE INVESTIGATION
4.1 Drilling and Soil Sample Collection
Three soil borings were drilled on October 29, 1996 for collection of confirmation
soil samples. Drilling services were provided by Cascade Drilling, Inc., of
Norwalk, California. The test holes were drilled using a Mobile B-53 hollow-stem
auger drilling rig equipped with 8-inch diameter augers, Drilling and sampling
protocol are described in Appendix A.
Figure 2 shows locations of Soil Borings CB-1, CB-2, and CB-3. The soil borings
were placed within and around areas that were previously identified to have high
concentrations of hydrocarbons in the soils. Soil Borings CB-1 and CB-2 were
installed on the east and west sides, respectively, of Island 1. Soil Boring CB-1
was drilled at an angle of 15° in order to collect samples beneath the island and
extended for a length of 45 feet (vertical depth of 43,5 feet). Soil Boring CB-2
was drilled at an angle of 20° in order to sample beneath the island and
extended for a length of 50 feet (vertical depth of 47,0 feet).
Soil Boring CB-3 was drilled on the south end of Island 3, at an angle of 20°.
Soil Boring CB-3 extended for a length of 30 feet (vertical depth of 28.2 feet).
Soil samples were collected at 5-foot intervals, Test holes were sealed with
bentonite-cement grout.
Boring logs are presented in Appendix B.
4.2 Analytical Testing of Soil Samples
Soil samples were submitted to BC Laboratories in Bakersfield, California and
analyzed for the following parameters:
· Total Petroleum Hydrocarbons as Gasoline (TPH-G) - California
DOHS Method;
· Total Petroleum Hydrocarbons as Diesel (TPH-D) - California DOHS
Method;
· Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX) - EPA 8020;
and
· Methyl-t-butylether (MTBE) - California DOHS Method.

4.3 Well Abandonment
A total of six wells were abandoned on October 30, 1996. The abandoned wells
included two dual completed soil vapor extraction wells, one bioventing well, and
one background vapor well. Well abandonment services were provided by
Cascade Drilling, Inc., of Norwalk, California.
The City of Bakersfield was notified prior to well abandonment activities at the
site. The abandoned wells were decommissioned by drilling them out using a
Mobile B-53 hollow-stem auger drilling rig equipped with 8-inch diameter augers,
The drilled out borings were sealed by pressure-grouting with bentonite-cement
grout.
5.0 INVESTIGATION FINDINGS
5.1 Analytical Results
Soil sample and analytical data are presented on Table 1, Analytical reports of
Chain-of-Custody documents are presented in Appendix C.
No petroleum hydrocarbon constituents were detected in any of the samples
from Boring CB-1. Very low concentrations of TPH-G (1.4 mg/kg), Benzene
(0.016 mg/kg), Ethylbenzene (0,038 mglkg), Total Xylenes (0.2 mg/kg), and
MTBE (0.014 mg/kg) were detected in Sample CB2-50, at an approximate
vertical depth of 47 feet bgs. TPH-D was encountered in Boring CB-3 in
samples CB3-10 at a concentration of 4900 mg/kg (vertical depth of 9.4 feet
bgs), CB3-15 at a concentration of 4200 mglkg (vertical depth of 14.1 feet bgs),
and CB3-30 at a concentration of 29 mg/kg (vertical depth of 28.2 feet bgs),
5.2 SVES Remediation Summary
Appendix D presents SVE monitoring data from October 27, 1995 to July 22,
1996. Concentrations of VOCs in site soils have decreased asymptotically
during the period over which soil remediation was performed. Since the initial
startup of the SVE system, a cumulative mass of approximately 2,547 Ibs of
VOCs have been removed from the soils.

6.0 CONCLUSIONS
The Unocal Service Station No. 7048 located at 2518 White Lane, Bakersfield,
California, has been decommissioned and the associated USTs, product lines,
and dispensers have been removed. SVE was implemented at the site to remove
VOCs from soil impacted by TPH-G beneath dispenser Island 1. Bioventing was
used to stimulate bioremediation of TPH-D-affected soil beneath Island 3.
6.1 Dispenser Island 1
No petroleum hydrocarbon constituents were detected in any of the samples
from Boring CB-1 on the east side of Island 1. Trace concentrations of TPH-G,
BTEX, and MTBE were detected at an approximate vertical depth of 47 feet bgs
on the west side of Island 1 (Sample CB2-50). SVE has been extremely
effective in reducing TPH-G in subsurface soils; based on data from the previous
site investigations and SVE system monitoring, approximately 2547 Ibs of TPH-G
(cumulative mass) have been removed from beneath Island 1.
6.2 Dispenser Island 3
TPH-D was encountered in Boring CB-3, on the south end of Island 3. TPH-D
was detected in CB3-10 at 4,900 mg/kg at 9.4 feet bgs and declined to 29 mg/kg
at 28.2 feet bgs (CB3-30), Based on data from the SVE system monitoring and
the previous site investigations, bioventing (SVE) has been very effective in
reducing concentrations of TPH-D beneath Island 3; TPH-D in soils has been
reduced from initial concentrations on the order of 12,000 mg/kg to present
concentrations of 4,900 mglkg and lower.
7 .0 RECOMMENDATIONS
Based on the conclusions presented above, PSI recommends the-followin'g:
. no further soil remediation in association with Island 1 be performed; and
. TPH-D affected soils be left in place. These soils do not present adverse
environmental or health impacts to the site because:
1, the depth to groundwater is estimated to be on the order of 175 feet
bgs;
2. the surface area in the vicinity of Island 3 consists of asphaltic concrete
which provides a barrier to direct contact and to infiltration of
precipitation and run-on of surface water; and
3, in-situ bioremediation by microbial action should continue to occur,
although at reduced rates due to the discontinued bioventing system,

PSI PROCEDURES FOR
SOIL SAMPLING AT UNDERGROUND STORAGE TANK SITES
The following procedures are utilized for the collection of soil samples:
i. Soil samples are obtained under the direction of a professional
engineer, geologist, or authorized representative of a State-approved laboratory.
Sample numbers and locations are approved by the city/county inspector, if
present on-site.
ii. All soil samples at tank removal sites are taken from the backhoe
bucket, unless the excavation has been safely graded or shored. Soil samples will
be collected from the interior portions of the excavator bucket, away from the
bucket's edges and teeth, to avoid potential cross-contamination. Approximately
one inch of soil is removed from the surface area where the sample is to be
collected and a clean, 6-inch long, 1-inch minimum diameter brass ring will be
pounded into the soil using a wooden mallet, or equivalent tool. No head-space
will be present in the ring once the sample is collected.
iii. In shallow excavations, as in under product lines, soil samples may
be taken by driving the brass tube directly into the trench side-wall.
iv. Soil samples are collected in thin-walled stainless steel or brass
cylinders 6" long by 1.5" or 2" diameter. Cylinders are pounded into the soil with a
wooden mallet or equivalent method when not using an auger or drilling
equipment.
v. Each end of the cylinder is covered with aluminum foil, capped with
polyethylene lids, taped, and labeled.
vi. Samples are transported in an ice chest containing blue ice or
equivalent and kept at approximately 4 degrees centigrade until delivery to a
California Department of Health Services-approved analytical laboratory.
vii. Chain-of-custody records produced in accordance with U.S.E.P.A
requirements are kept to track the possession of a sample from the time it is taken
in the field until the time it is analyzed.

PSI PROCEDURES FOR
SOIL SAMPLING IN SHALLOW EXCAVATIONS
The following procedures are utilized for the collection of soil samples:
i. Soil samples are obtained under the direction of a professional
engineer, geologist, or authorized representative of a State-approved laboratory.
Sample numbers and locations are approved by the city/county inspector, if
present on-site.
ii. All soil samples are taken from the backhoe bucket, unless the
excavation has been safely graded or shored. Soil samples will be collected from
the interior portions of the excavator bucket, away from the bucket's edges and
teeth, to avoid potential cross-contamination. Approximately one inch of soil is
removed from the surface area where the sample is to be collected and a clean, 6-
inch long, 1-inch minimum diameter brass ring will be pounded into the soil using a
wooden mallet, or equivalent tool. No head-space will be present in the ring once
the sample is collected.
iii. In shallow excavations, soil samples may be taken by driving a brass
tube directly into the excavation bottom or side-wall.
iv. Soil samples are collected in thin-walled stainless steel brass
cylinders 6" long by 1.5" or 2" diameter. Cylinders are pounded into the soil with a
wooden mallet or equivalent method when not using an auger or drilling
equipment.
v. Each end of the cylinder is covered with aluminum foil, capped with
polyethylene lids, taped, and labeled.
vi. Samples are transported in an ice chest containing blue ice or
equivalent and kept at approximately 4 degrees centigrade until deliv~ry to a
California Department of Health Services-approved analytical laboratory.
vii. Chain-of-custody records produced in accordance with U.S. E.P.A.
requirements are kept to track the possession of a sample from the time it is taken
in the field until the time it is analyzed.
