SITE ASSESSMENT REPORT TEXACO SERVICE STATION 4050 GOSFORD ROAD BAKERSFIELD, CALIFORNIA July 21, 2002 1.0 INTRODUCTION The property is currently utilized as an operational Texaco Service Station. It is located on the northeast comer ofthe intersection of Gosford Road and White Lane in Bakersfield, California (Figure 1). The need for additional assessment was outlined in a letter from the City of Bakersfield Fire Department Environmental Services dated October 24, 2001. The purpose of the assessment is to more fully define the vertical and lateral extent ofpetroleum 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 and east of the subject property; White Lane followed by a Unocal 76 service station are located to the south of the subject site; Gosford Road followed by residential housing are located to the south. An active gasoline service station currently occupies the subject property. The property consists of a service station building, a carwash, two dispenser islands each equipped with two multi - product dispenser pumps, three 10,000 gallon and on 12,000 gallon double -wall fiberglass gasoline underground storage tanks (USTs), and associated piping. 3.0 SITE HISTORY On January 19, 2000, Pacific Environmental Group (PEG) conducted a Phase II environmental assessment as the subject site. Six soil borings were advanced to depths of 20 to 40 feet below surface grade (BSG). Soil analytical results revealed low -level hydrocarbon impact near the UST's and northwest dispenser island (soil borings BB -1, BB -2, and BB -6). I422.EQL.00 1 July 21, 2002 r i WG IR, Southwest, Inc. On July 5, 2001, IT conducted soil sampling beneath the product piping and dispensers during station upgrade activities. Total petroleum hydrocarbons as gasoline and diesel (TPH -g and TPH- d) were detected in soil beneath the product piping in sample locations P -1 and P -2 and dispenser D -1, at concentrations ranging from 0.78 mg/kg to 210 mg/kg. Methyl tert-butyl ether (MTBE) was detected in soil beneath all product piping and dispenser sample locations, except D -2, at concentrations ranging from 0.011 mg/kg to 13 mg/kg. On July 17, 2001, IT returned to the site to supervise limited impacted soil overexcavation. Approximately 50 cubic yards of soil was removed from product piping areas P -1 and P -2 and dispenser D -1. Confirmation soil samples were collected from the bottom and sidewalls of the excavations. TPH -g and MTBE were detected in all confirmation soil samples collected from P -1 and P -2. TPH -g concentrations ranged from 3.5 mg/kg to 7.9 mg/kg and MTBE concentrations ranged from 6.1 mg/kg to 16 mg/kg, by EPA Method 8260B. TPH -g concentrations were not detected in confirmation soil samples collected from D -1. MTBE concentrations were detected in the confirmation soil samples collected from D -1 at 0.014 mg/kg and 0.0088 mg/kg. 4.0 REGIONAL AND LOCAL HYDROGEOLOGIC SETTING The geologic conditions in the site vicinity are characterized from alluvial deposits underlain by marine and non - marine sedimentary units, metamorphic rocks, and crystalline basement material. Surface and near - surface conditions is designated by the U.S. Geological Survey (USGS) as older alluvium, deposited in northwest - dipping alluvial fans resulting from 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 discontinuous lenticular bodies of sandy clay and silt. Regionally, the surface of these old alluvial fans in undulatory, with a distinct dip toward the Kern River to the northwest of the site. The site itself is located along one of the crests of the alluvial fan 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 Nevada Mountains. r 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 the consolidated non - marine sedimentary units and within I422.EQL.00 2 July 21, 2002 4 W(G IR Southwest, Inc. fracture zones of the crystalline basement rock. The most prominent subsurface features controlling the groundwater flow direction are the groundwater barriers formed by the northwest- to-southwest trending Edison Fault and subparallel splays of this fault, located south and north of the site, respectively. 5.0 FIELD ACTIVITIES 5.1 DRILLING AND SAMPLING PROCEDURES Six soil borings, (BB -7 through BB -12) were drilled and sampled on June 20 and 21, 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 -7 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 -7, BB -8, BB -11 and BB -12 were drilled vertically to approximate depths of60 feet BSG. Borings BB -9 and BB -10 were drilled vertically to an approximate depth of65 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 CUE 85 hollow stem auger drilling rig was utilized for the advancement of soil borings BB -7 through BB -12. Pre- cleaned and/or steam cleaned 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 BB -7 through BB -12. 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 Teflon —lined end caps. The samples were labeled with all pertinent sampling information, and then packed on ice for subsequent shipment to a California Department ofHealth Services (CDHS)- certified 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 equipment 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 surface with concrete to match the existing surface. Chain ofcustody protocol was followed throughout field and laboratory procedures. 422.EQL.00 3 July 21, 2002 t; G f; ,, , , t; G t fir. , . 7'., _ t; G i W GI Southwest, I . 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 ofdrilling was advanced utilizing hand auger techniques. 5.4 LABORATORY ANALYSES Soil samples collected from 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, benzene, toluene, ethylbenzene, and total xylenes (BTEX), and MTBE. 6.0 RESULTS OF INVESTIGATION Sediments encountered during the drilling investigation are summarized generally as follows: interbedded sand, silty sand, sandy silt, and clay mixtures. Boring logs are attached as Appendix A. 1 Analytical results of the soil samples indicated detectable MTBE concentrations in all of the boring locations. The highest MTBE concentrations occurred in borings BB -9 (10-20 feet BSG) and BB -11 5 -20 feet BSG) with a maximum concentration of 16,000 gg/kg in boring BB -9 at 20 feet BSG. Analytical results of the soil samples indicated detectable TPH -g concentrations in all of the boring locations. The highest TPH -g concentrations occurred in borings BB -9 (10 -20 feet BSG) and BB -11 10 -30 feet BSG) with a maximum concentration of 15 mg/kg in boring BB -9 at 20 feet BSG. TPH-d concentrations were reported in boring BB -9 with a maximum concentration of 4.6 mg/kg at 25 feet BSG. There were no detections of BTEX concentrations in any of the samples. Analytical results for TPHg, BTEX, and MTBE concentrations are summarized in Table 1. Laboratory reports 422.EQL.00 4 July 21, 2002 W IR. G Southwest, Inc. 1 and chain of custody documents are provided in Appendix B. 7.0 SOIL DISPOSAL The drill cuttings generated during the field investigation were stored temporarily on site in 55 -gallon 1 DOT - approved steel drums pending characterization. Each drum was labeled with the site name and address, generation date, and type and source of the material it contains. Following characterization, the drums will be transported to an appropriate facility for disposal. Copies of disposal documentation will be forwarded upon receipt. 8.0 SUMMARY AND CONCLUSIONS Five soil borings were advanced and sampled at the subject site on June 20 and 21, 2002 to more fully define the vertical and lateral extent ofpetroleum hydrocarbons beneath the site. Sediments encountered during the drilling investigation consisted of interbedded sand, silty sand, sandy silt, and clay mixtures. Detectable TPH -g was identified in borings BB -7, BB -8, BB -9, BB -10, BB -11, and BB -12 ranging in 1 concentration from 0.068 mg/kg to 12 mg/kg. Detectable TPH -d was identified in boring BB -9 ranging in concentration from 2 mg/kg to 4.6 mg/kg. Detectable benzene concentrations were not identified in any of the borings. Detectable MTBE was identified in borings BB -7, BB -8, BB -9, BB- 10, BB -11, and BB -12 ranging in concentration from 5 µg/kg to 16,000 µg/kg. Respectfully submitted, J WGR Southwest, Inc.

No.: 1903 ph: (562) 799 -8510 fax: Date Reported: 7/10/2002 Matrix spike (MS) and matrix spike duplicate (MSD) samples are chosen and tested at random from an analytical batch of "like" matrix to check for possible matrix effect. 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.
