SITE ASSESSMENT REPORT TEXACO SERVICE STATION 3698 MING AVENI.~ BAKERSFIELD, CALIFORNIA May 23, 2002 1.0 INTRODUCTION The property is currently utili?~l as an operational Texaco Service Station. It is located on the northeast comer of the intersection of ~ng Avenue and Real Road in Bakersfield, California (Figure 1). The need for additional assessment was outlined in a letter from the City of Bakersfidd Fire Department Environmental Services dated October 24, 2001. The purpose of the assessment is to more fully define the vertical and lateral extent of petroleum hydrocarbons beneath the site. 2.0 SITE SETTING The site is located in a commercial and residential district of Bakersfield. A shopping center is directly adjacent to the north with a residential area adjacent to the shopping center. A shopping center is directly adjacent to the east of the subject property. 1Wing Avenue followed by a small strip mall are located to the south. A vacant lot is located to the west. An active gasoline service station currently occupies the subject property. The property consists of a service station building, four dispenser islands each equipped with four multi-product dispenser pumps, four 10,000 gallon double-wall fiberglass gasoline underground storage tanks (USTs), and associated piping. 3.0 SITE HISTORY On January 11 and 12, 2000, seven soil borings (BB-1 through BB-7) were drilled during a baseline environmental site assessment investigation conducted by IT Corporation (IT). The borings were drilled to total depths ranging from 20.5 feet to 40.5 feet BSG using a direct-push 422.EQL.00 1 May 23, 2002 I I I I I I I I I I I I I I I I WGIK Southwest, Inc. technology (DPT) Geoprobe drill fig. Total petroleum hydrocarbons as gasoline and diesel (TPH-g and TPH-d), benzene, and methyl ten-butyl ether (MTBE) were not detected in any of the soil samples collected and analyzed as part of this investigation. Total recoverable petroleum hydrocarbons (TRPH) were detected in four of samples collected fi.om boring BB-7 (near the waste oil UST) ranging fi.om 11 mg/kg at a depth of 20 feet BSG, to 18 mg/kg at a depth of 5 feet BSG. On July 25, 2001, IT supervised the removal of four gasoline UST's, one waste oil UST, product piping and dispensers. Soil sampling was conducted by IT beneath the five UST's, product piping, and product dispensers. TPH-g was detected beneath the west side of T-2 and beneath D- 1, at concentrations of 0.83 mg/kg and 0.92 rog/kg, respectively. MTBE was detected in soil samples fi.om the east sides of T-2, T-3, and T-4 and beneath D-l, at concentrations of 0.036 mg/kg, 0.18 mg/kg, 0.10 mg/kg and 0.27 mg/kg, respectively. Benzene was not detected in any of the soil samples collected on July 25, 2001. IT performed limited comamination soil over-excavation based on field observations during UST removal activities. Over-excavation was done beneath the east side of T-l, T-2, and T-3. Approximately 75 cubic yards of soil was removed. The confirmation soil sample collected from the bottom of the over-excavation beneath T-2 was non-detect for TPH-g, TPH-d, benzene, and MTBE. The confirmation soil sample collected beneath T-3 had a TPH-g concentration of 980 mg/kg and a TPH-d concentration of 1,100 mg/kg. MTBE was not detected in the confirmation soil sample collected from the bottom of the over-excavation beneath T-3. 4.0 REGIONAL AND LOCAL HYDROGEOLOGIC SETTING The geologic conditions in the site vicinity are characterized by alluvial deposits underlain by marine and non-marine sedimentary units, metamorphic rocks, and crystalline basement material. Surface and near-surface soil is designated by the U.S. Geological Survey (USGS) as older alluvium, deposited in northwest-dipping alluvial fans resulting fi'om outwash from the Sierra Nevada mountain range to the east. This alluvium is composed primarily of poorly graded and unconsolidated sands, sandy gravels, and occasional disc0minuous lenticular bodies of sandy clay and silt. Regionally, the surface of these old alluvial fans is undultory, with a distinct dip toward 422.EQL.00 2 May23,2002 I I I I I WGIK Southwest, Inc. the Kern River to the northwest of the site. The site itself is located along one of the crests of the land surface 'ripples', at an elevation of approximately 390 feet above mean sea level (MSL). The total thickness of the alluvial fan deposits is estimated to range from approximately 600 feet west of the site to over 4,000 feet near the Sierra Mountains. The site lies within the Edison hydrogeologic sub-area of the Edison-Maricopa area. Uppermost groundwater within this area occurs within the old alluvial fan deposits. In the site vicinity, deeper aquifers of limited areal extent are present in consolidated non-marine sedimentary units and within fracture zones of the crystalline basement rock. The prominent subsurface features controlling the groundwater flow direction are the groundwater barriers formed by the northwest- to-southeast trending Edison fault and subparallel splays of this fault, located south and north or this site, respectively. Lithology beneath the site is predominately Recent alluvium composed of silty sand and silty sand with grave[ with interbedded well- and poorly-graded sand with gravel, and well graded gravel with sand, to a total depth of 40.5 feet BSG. Depth to groundwater is estimated to be over 150 feet BSG, with a southerly flow direction. 5.0 FIELD ACTIVITIES 5.1 DRILLING AND SAMPLING PROCEDURES Five soil borings, (BB-8 through BB-12) were drilled and sampled on May 6 and 7, 2002 at the subject property to more fully define the vertical and lateral extent of petroleum hydrocarbons beneath the site. Boring locations are shown in Figure 2. Borings BB-8 through BB-12 were drilled to a minimum depth of 50 feet BSG or 20 feet beyond hydrocarbon impacted soils as defined by the PID readings. Borings BB-8 and BB-12 were drilled vertically to approximate depths of 55 feet BSG. Boring BB-9 was drilled vertically to an approximate depth of 50 feet BSG. Boring BB-10 was drilled vertically to an approximate depth of 85 feet BSG. Boring BB-11 was drilled vertically to an approximate depth of 65 feet BSG. During this investigation standard practices and procedures for field sampling as outlined in Publication SW-846, Second Edition, United States Environmental Protection Agency and any local agency mandated sampling procedures were followed. A hollow stem auger limited access drilling rig was utilized for the advancement of soil borings BB-8 through BB-12. Pre-cleaned and/or steam cleaned 422.EQL.00 , 3 May 23, 2002 I I I I I I I I I I I I I I I I I I \WG] Southwest, Inc. augers were used throughout the drilling operation to prevent potential cross contamination. Undisturbed soil samples were collected for analyses and lithologic characterization at approximate five-foot depth intervals from soil borings B-1 through B-7. The soil samples submitted for analyses were collected in an 18-inch long 2.0-inch O. D. split-spoon sampler lined with 2.0 inch O. D. stainless steel tubes. The sleeves were sealed at each end with TeflonTM -lined end caps. The samples were labeled with all pertinent sampling information, and then packed on ice for subsequent shipment to a California Department of Health Services (CDHS)-cerfified laboratory for analyses. The soil in the remaining tubes was screened for hydrocarbon vapors with a portable organic vapor analyzer (OVA), described and logged by the field geologist in accordance with the Unified Soil Classification System (USCS). All sampling equipmem was decontaminated between sampling episodes utilizing a triple rinse method consisting of a wash with Alconox (or equivalent) solution, an initial rinse with tap water, and a final rinse with deionized water. Immediately following sampling all borings were backfilled with bentonite grout. All borings were completed at mrface with concrete to match the existing surface. Chain of custody protocol was followed throughout field and laboratory procedures. 5.2 HEALTH AND SAFETY PLAN A site specific Health and Safety Plan detailing all known or potential hazards and emergency response procedures was prepared prior to field operations. All on-site personnel reviewed the plan and a "tailgate" safety meeting was conducted prior to initiation of field activities. The plan was maintained on-site throughout the duration of field activities. 5.3 DRILL SITE CLEARANCE Prior to the initiation of field operations, drilling locations were marked with white paint and Underground Service Alert (USA) was contacted to identify any potential subsurface obstructions and/or conflicts. In order to further insure that no underground utilities or obstructions existed at the proposed boring locations a geophysical survey was conducted at the property prior to conducting the filed investigation. Additionally, the initial 5 feet of drilling was advanced utilizing hand auger techniques. 5.4 LABORATORY ANALYSES Soil samples collected fi.om borings adjacent to the gasoline dispenser islands and/or fuel storage tanks were submitted to a State certified laboratory for analysis by EPA Method 8260B for TPH-g TPH-d, 422.EQL.00 4 May 23, 2002 I t WGI[ Southwest, linc.

The MS and MSD will provide site specific matrix data only for those samples which are spiked by the laboratory. Since the MS and MSD are chosen at random from an analytical batch, the sample chosen for spike purposes may or may not have been a sample submitted in this sample delivery group. The validity of the analytical procedures for which data is reported in this analytical report is determined by the Laboratory Control Sample (LCS) and the Method Blank (MB). The Laboratory Control Sample (LCS) and the Method Blank (MB) are processed with the samples and the MS/MSD to ensure method criteria are achieved throughout the entire analytical process. Any other exceptions associated with this report will be footnoted in the analytical result page(s) or the quality control summary page(s). Please do not hesitate to contact us if you have any questions or comments pertaining to this data report. Please reference the above Certificate of Analysis Number. This report shall not be reproduced except in full, without the written approval of the laboratory. The reported results are only representative of the samples submitted for testing.
