SITE ASSESSMENT REPORT TEXACO SERVICE STATION 4050 GOSFORD ROAD AT WHITE LANE BAKERSFIELD, CALIFORNIA June 16, 2003 1.0 INTRODUCTION The property is currently utilized as an operational Texaco Service Station. It is located on the northeast corner of the intersection ofGosford 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. The purpose of the assessment was to more fully define the vertical and lateral extent of petroleum hydrocarbons beneath the site. This report summarizes the assessment activities conducted on May 1 and 6-8, 2003. 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. 1 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 1 ground surface (bgs). Soil analytical results revealed low -level hydrocarbon impact near the I423.EQL.00 1 June 16, 2003 i t 1 l Southwest, Inc. UST's and northwest dispenser island (soil borings BB -1, BB -2, and BB -6). 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. On June 20 -21, 2002, WGR Southwest, Inc. conducted a site assessment to more fully define the vertical and lateral extent of the petroleum hydrocarbons beneath the site. The assessment consisted of advancing six soil borings (BB -7 through BB -12) to a depth of 60 feet to 65 feet bgs. Detectable TPH -g was identified in borings BB -7, BB -8, BB -9, 1313-10, BB -11, and BB -12 ranging in 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 gg/kg to 16,000 µg/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 423.EQL.00 2 June 16, 2003 WG Southwest, Inc. mountain range to the east. This alluvium is composed primarily ofpoorly 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. 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 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. According to the records at the Kern County Water Agency, depth to groundwater measurements in the vicinity of the subject site taken in October of 2002 were approximately 160 feet below grade surface (bgs). 5.0 FIELD ACTIVITIES 5.1 DRILLING AND SAMPLING PROCEDURES Eight soil borings, (BB -13 through BB -20) were drilled and sampled on May 1 and 6-8, 2003 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 -13 through BB -20 were drilled vertically to approximate depths of 85 feet bgs. 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 1 mandated sampling procedures were followed. A CME 95 hollow stem auger drilling rig was utilized for the advancement of soil borings BB -13 through BB -20. 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 I423.EQL.00 3 June 16, 2003 t WG IK Southwest, 1(nc. five -foot depth intervals from soil borings BB -13 through BB -20. 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 delivery to a California Department of Health 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 Portland cement. All borings were completed at surface 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 7 feet of drilling was advanced utilizing air- knifing techniques 5.4 LABORATORY ANALYSES Soil samples collected from borings adjacent to the gasoline dispenser islands and/or fuel storage tanks I were submitted to a State certified laboratory for analysis for total petroleum hydrocarbons as gasoline TPH -g) by EPA Method 8015M and for BTEX, MME and oxygenates (TBA, DIPS, ETBE, and TAME) by EPA Method 8260B.
