LABORATORY REPORTS Site Assessment Report Chevron Facility No. 9-2718 August 16, 1995 ii IDD~I GROUNDWATER ODD TECHNOLOGY ® I I I I I I I I I I I I I I I I I I I 1.0 INTRODUCTION Groundwater Technology, Inc. has been contracted by Chevron U.S.A. Inc. to conduct assessment activities their facility no. 9-2718. The site is located at Stockdale Highway and Village Lane in Bakersfield, California (Figures 1 and 2). The purpose of the assessment is to determine the extent of hydrocarbons in soil associated with the flexible product line at the east end of tank no. 2, as requested by the City of Bakersfield (letter dated April 10, 1995). This report presents site background, assessment procedures, sampling protocol, and findings of the assessment. 2.0 BACKGROUND On March 1, 1995, RLW Equipment Company encountered hydrocarbon bearing soil while replacing a flexible product line. Soil samples were collected at depths of 2- and 6-feet on the east ends of the unleaded-regular and unleaded-plus USTs (Figure 2). The samples were analyzed for benzene, toluene, ethyl benzene, and xylenes (BTEX) and total petroleum hydrocarbons as gasoline (TPHG). Benzene concentrations ranged from 540 to 230 mg/kg, respectively, In the 2- and 6-foot samples associated with the unleaded-regular UST (Table 1). The concentration of TPHG in these samples ranged from 22,000 mg/kg (at 2 feet) to 12,000 mg/kg (at 6 feet). No analytes were detected in samples associated with the unleaded-plus UST. 3.0 GEOLOGY/HYDROGEOLOGY Chevron facility no. 9-2718 is located in the southwest portion of Bakersfield. The approximate elevation of the facility is approximately 385 feet above mean sea level. The site is located on the alluvial plain of the Kern River. Topography in the region is flat, and no natural bodies of water adjoin the site. Approximately 4,500 feet east of the site is the Stine Canal. The station is located in a commercial area and is approximately 3,950 feet north of the nearest school. 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 at the site consist primarily of very flne- to coarse-grained sand and silty sand. Site Assessment Report Chevron Facility No. 9,2718 August 16. 1995 1 IDD~I GROUNDWATER ODD TECHNOLOGY ,~ I I I I I I I I I I I I I I I I I I I An unconfined aquifer is present below the site at a depth of approximately 210 feet. Based on regional data, the gradient of this aquifer is essentially flat (KCWA, 1994). Shallow, perched water has not been identified in the vicinity of the site (KCWA, 1995). 4.0 ASSESSMENT PROCEDURES Assessment activities conducted at the site by Groundwater Technology were completed on July 5, 1995. One vertical boring (B1) was advanced on the east end of the unleaded regular UST to a total depth of 40 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. 5.0 ANALYTICAL RESULTS Three soil samples (including the deepest) were analyzed by a state-certified laboratory for BTEX and TPHG. No hydrocarbons were detected (Table 2). The laboratory reports are presented in Appendix C. 6.0 SUMMARY AND CONCLUSIONS The findings of the site assessment activities at Chevron facility 9-2718 can be summarized as follows: · Sediments encountered during the drilling activities consist primarily of very fine- to coarse-grained sand and silty sand; · An unconfined aquifer is present below the site at a depth of approximately 210 feet; · Hydrocarbons were detected in grab samples collected from a depth of 2- and 6-feet at the east end of the unleaded-regular UST. · On July 5, 1995, Groundwater Technology supervised the drilling of one boring (B1) on the east end of the unleaded-regular UST. Three soil samples were analyzed for BTEX and TPHG. No hydrocarbons were detected. The assessment has indicated the extent of the hydrocarbons in soil is limited to a depth of approximately 6 feet. Benzene and TPHG were not detected in any of the samples submitted for the Site Assessment Report Chevron Facility No. 9'2716 August 16, 1995 2 IDD~I GROUNDWATER ODD TECHNOLOGY c§ I I I I I I I I I I I I I I I I I I I current assessment. An extensive vadose-zone buffer of approximately 204 feet exists between the hydrocarbons detected in grab samples and groundwater. Groundwater Technology recommends that no further action be required at this site.

Samples were collected from the borings as described in Section B.2. Upon completion, the boring was backfilled with a 5-sack sand/cement slurry and capped with cold patch asphalt. B.2 SOIL SAMPLING Soil samples were collected at 5-foot inteNals with a split-spoon sampler. The sampler was driven ahead of the augers into undisturbed sediments using a 140 lb. down-hole, slide-hammer. The sampler was fitted with stainless steel or 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 at either end of the tube. The tube was sealed at each end with a tetlon 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 analytical laboratory. Another sample tube retrieved from the sampler was field screened with a PID for volatile organic compound (VOG) emissions. To do this approximately 2/3 of the material in the sample tube was removed 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 inteNal. The material from the second sample tube was described on the drilling log of the boring using visual classification according to the Unified Soil Classification System. Color, grain size, and sorting charts were used to aid in the soil classification. 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 bucket of tap water and given a final rinse in a bucket of distilled water. 8.3 LA80RA TORY ANALYSIS Soil samples were shipped via overnight courier to GTEL Environmental Laboratories, Inc. (Certification No. E1075) in Concord, California. The temperature within the ice chest was recorded when the samples were received at the laboratory.
