LABORATORY REPORTS m I FLUOR DANIEL GTI ~ I I Phase II Baseline Soil Assessment Report Page 1 I Chevron Facilib/No. 9-4025 November 28~ 1997 I 1.0 INTRODUCTION Fluor Daniel GTI has been contracted by Chevron Products Company to conduct a Phase II baseline soil assessment at their facility no. 9-4025. The site is located at 800 34th Street in Bakersfield, California (Figures I and 2). The purpose of the assessment is to establish a baseline of soil conditions prior to property transfer. This report presents site background, assessment procedures, sampling protocol, and findings of the assessment. 2.0 BACKGROUND Dudng 1988, four steel USTs (three gasoline and one used-oil) were removed and replaced with three double-wall fiberglass, 10,000-gallon gasoline USTs and one double-wall fiberglass, 1,000-gallon used-oil UST (Figure 2 and Table 1). Following tank removal, samples were collected beneath the former tanks, dispensers, and/or product piping to determine if hydrocarbons were present. No significant hydrocarbon contamination was detected and the Kern County Environmental Health Services Department granted closure (letter dated May 1988). No other environmental acfivifies are known to have been performed at the facility. 3.0 GEOLOGY/HYDROGEOLOGY Chevron facility no. 9-4025 is located in the central portion of Bakersfield in a mixed commercial/residential area. The approximate elevation of the facility is 410 feet above sea level. Topography in the region is flat, and no natural bodies of water adjoin the site. The site overlies alluvial-fan deposits of the Kern River (CDMG, 1965). Sediments underlying the region consist of fluvial deposits including silt, sand, and gravel. Sediments encountered during drilling activities consist primarily of fine- to coarse-grained sand. An unconfined aquifer is present below the site at a depth of approximately 150 feet. The gradient of this aquifer is to the southeast (KCWA, 1995a). Shallow, perched water has not been identified in the vicinity of the site (KCWA, 1995b). Drilling logs with detailed lithologic descriptions are provided in Appendix A. 4.0 ASSESSMENT PROCEDURES Assessment activities were completed on November 20 and 25, 1997. Four slant borings (B1 through B4) were drilled to determine soil conditions in the vicinity of the dispensers and USTs. The total depth of each boring was 30 feet. Undisturbed soil samples were collected at 5-foot intervals. Specific sampling, boring abandonment, and waste-handling procedures are discussed in detail in Appendix B. FLUOR DANIEL GTI ~ Phase II Baseline Soil Assessment Report Page 2 I Chevron Facility No. 9-4025 November 28~ 1997 I 5.0 SOIL SAMPLE ANALYTICAL RESULTS Two soil samples from each of the four borings were shipped via overnight courier to Del Mar Analytical I (ELAP Certification No. 1197) in Irvine, California. Samples collected beneath the dispensers and gasoline USTs (B1 through B3) were analyzed for benzene, toluene, ethylbenzene, and xylenes (BTEX), total petroleum hydrocarbons as gasoline (TPHG), and methyl tert-butyl ether (MTBE) using EPA methods I 8020, 8015-modified and 8020, respectively. Samples collected beneath the used-oil UST were analyzed for halogenated volatile organics, total recoverable petroleum hydrocarbons (TRPH), and total lead using EPA methods 8010, 418.1, and 6010, respectively (Table 2). BTEX, TPHG, MTBE, and halogenated I volatile organics were not detected. TRPH and total lead were detected in soil samples collected at a depth of 15 and 20 feet from boring B4. Concentrations of TRPH and total lead in soil ranged from 18 to 21 rog/kg and 2.4 to 2.1 mg/kg, respectively (Table 2). Laboratory reports and chain-of-custody documents I are presented in Appendix C. I 6.0 SUMMARY AND CONCLUSIONS I The findings of the baseline assessment activities at Chevron facility 9-4025 can be summarized as follows: · Sediments encountered during the drilling activities consist primarily of fine- to coarse- I grained sand; · An unconfined aquifer is present below the site at a depth of approximately 150 feet; and I · Four borings were drilled and sampled to determine soil conditions beneath the dispensers and USTs. Six soil samples from three borings (B1 through B3) were analyzed for BTE×, TPHG, and MTBE. No hydrocarbons were detected. Two soil samples from boring B4 I were analyzed for halogenated volatile organics, total lead, and TRPH. Halogenated volatile organics were not detected. TRPH and total lead were detected at Iow concentrations.

Upon completion, the borings were backfilled the soil cuffings and I capped with cold patch asphalt. B.2 SOIL SAMPLING I Soil samples were collected at 5-foot intervals with a split-spoon sampler. The sampler was ddven ahead of the augers into undisturbed sediments using a 140 lb. down-hole, slide-hammer. The sampler was titted I with brass sample tubes. When the filled sampler was retrieved, the tube to be submitted for analysis was separated from the other tubes with a knife and sealed in such a way that no significant headspace was left I at either end of the tube. The tube was sealed at each end with a teflon sheet, a plastic cap, and tape to secure the plastic cap. The sample was labeled to indicate date and time of sample collection, boring number and depth of the sample. The sample was placed on ice in an ice chest pending delivery to an I analytical laboratory. I Another sample tube retrieved from the sampler was field screened with a PID for volatile organic compound (VOC) emissions. To do this approximately 2/3 of the matedal in the sample tube was removed I and the tube was capped on both ends with a plastic cap. The tube was then shaken vigorously for several seconds and the inlet to the PID was inserted into a small hole in one of the caps. The PID reading was recorded on the drilling log for that sample interval. I The material from the second sample tube was described on the drilling log of the boring using visual Iclassification according to the Unified Soil Classification System. Color, grain size, and sorting charts were used to aid in the soil classitication. I Between sampling events, the sampling equipment was cleaned using a three-bucket wash system. In this system, the tubes and samplers are scrubbed in a bucket of biodegradable detergent, rinsed in a second I bucket of tap water and given a final rinse in a bucket of distilled water. B.3 LABORATORY ANALYSIS Soil samples were shipped via overnight courier to Del Mar Analytical in Irvine, California. Soil samples associated with the gasoline dispensers and USTs were extracted using EPA method 5030 and analyzed for BTEX/MTBE and TPHG concentrations using EPA methods 8020 and 8015-modified, respectively. Soil samples associated with the used-oil UST were analyzed for TRPH, total lead, and halogenated volatile organics by EPA methods 418.1,6010, and 8010, respectively. I FLUOR DANIEL GTI ~ I Phase II Baseline Soil Assessment Report Page B2 Chevron Facilit7 No. 9-4025 October 22~ 1997 Detection limits for the analytes were as follows: · 0.005 mg/kg for BTE; · 0.015 mg/kg for X; · I mg/kg for TPHG; · 1 mg/kg for MTBE; · 2.0 mg/kg for total lead; · 5.0 mg/kg for oil & grease (TRPH); and · variable detection limits for halogenated volatile organics. B.4 WASTE MANAGEMENT The soil cuttings were screened for the presence of hydrocarbons using a photoionization detector (PID). No hydrocarbons were detected. The soil cuttings were used to backfill the borings since no hydrocarbons were detected.
