VAPOR EXTRACTION WELL INSTALLATION REPORT TEXACO SERVICE STATION 4050 GOSFORD ROAD at WHITE LANE BAKERSFIELD, CALIFORNIA October 27, 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 of Gosford Road and White Lane in Bakersfield, California 1 ( Figure 1). The purpose of the assessment was to install five nested vapor extraction wells adjacent to areas beneath the site where hydrocarbon and/or oxygenate impaction was previously detected. This report documents the assessment activities conducted on September 22 -25, 2003 at the subject property. 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 west. 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 one 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 ground surface (bgs). 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). 423.EQL.00 1 October 27, 2003 Fil F I JI 1 WGIK 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 -l. 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 evaluate 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, 1313-9, BB -10, BB -11, and BB -12 ranging in concentration from 5 µg/kg to 16,000 µg/kg. On May 1 and 6 -8, 2003, WGR Southwest, Inc. conducted a site assessment to further evaluate the vertical and lateral extent of the petroleum hydrocarbon concentrations detected during the previous site assessment beneath the site. The assessment consisted of advancing eight soil borings (BB -13 through BB -20) to a depth of 85 feet bgs. Detectable TPH -g was identified in borings BB -14, BB -15, BB -17, and BB -18 ranging in concentration from 0.50 mg/kg to 5.2 mg/kg. Detectable benzene concentrations were not identified in any of the borings. Detectable MTBE was identified in borings BB -13 through BB -20 ranging in concentration from 5.0 µg/kg to 47,000 µg/kg. Detectable TBA was identified in borings BB -13 through BB -19 ranging in concentration from 61 µg/kg to 16,000 423.EQL.00 2 October 27, 2003 A 1 I W GIK Southwest, Inc. g/kg. Detectable Ethanol was identified in borings BB -15 and BB -20 ranging in concentration from 270 µg/kg to 12,000 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 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. 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). The closest receptor well (State well # 30S/27E -20A01 M) is located approximately 3,698 feet due south of the subject site. 5.0 FIELD ACTIVITIES 5.1 DRILLING AND SAMPLING PROCEDURES Five nested vapor extraction wells (VEW -1 through VEW -5) were drilled and installed on September 423.EQL.00 3 October 27, 2003 1 1 WGIK Southwest, Inc. 22 -25, 2003 at the subject property. Well locations are shown in Figure 2. Wells VEW -IA and VEW -1B were installed to approximate depths of 30 feet bgs and 55 feet bgs respectively. Wells VEW -2A and VEW -2B were installed to approximate depths of 30 feet bgs and 60 feet bgs respectively. Wells VEW -3A and VEW -3B were installed to approximate depths of 25 feet bgs and 50 feet bgs respectively. Wells VEW-4A and VEW-413 were installed to approximate depths of 30 feet bgs and 65 feet bgs respectively. Wells VEW -5A and VEW -513 were installed to approximate depths of 30 feet bgs and 65 feet bgs respectively. 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 limited access drilling rig was utilized for the advancement of soil borings. 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 the surface from soil borings VEW -1 through VIEW-5. The soil samples from the borings were collected in an 18 -inch long, 2.5 -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 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. Chain of custody protocol was followed throughout field and laboratory procedures. 5.2 VAPOR EXTRACTION WELL INSTALLATION Vapor extraction well (VEW -IA) was constructed with 20 feet of 2 -inch O. D., schedule 40 PVC, 0.020" slotted well screen set from approximately 30 feet to 10 feet bgs, (VEW -1B) was constructed with 15 feet of 2 -inch O.

Number 3 sand was used as a filter pack to approximately 2 -3 feet above each of the screened intervals. Immediately above each filter pack, a seal consisting of a minimum of 3 feet of hydrated chipped bentonite was placed. The wellheads were secured with a locking well cap and completed with a 12- inch- diameter Emco- Wheaton traffic lid installed in a minimum 24- inch - diameter concrete pad. Well construction details are presented in the boring logs attached as Appendix A. 5.3 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. 5.4 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 and the initial 7 feet of drilling was advanced utilizing air - knifing techniques. 423.EQL.00 5 October 27, 2003 1 1 t 1 1 1 1 L 1 1 n WGIK Southwest, hic. 5.5 LABORATORY ANALYSES Soil samples collected from borings VEW -1 through VEW -5 were submitted to a State certified laboratory for analysis by EPA Method 8015M for TPH -d and TPH -g and by EPA Method 8260B for BTEX, MTBE, and other fuel oxygenates. 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.
