(ESE) of the base of the excavation pit where a 3,000 gallon underground gasoline storage tank; fuel dispenser, and associated product: pipeline were removed on May 1, 1992 from Bakersfield College located at 1801 Panorama Drive in the city of Bakersfield, California. Figure 1 is a vicinity map showing the location of the site and Figure 2. is a site map showing the location of the former storage tank, dispenser, product pipeline, and the soil samples. 2.0 SITE DESCRIPTION 2.1 S itc The site is located at 1801 Panorama Drive in the city of Bakersfield in Kern County, California. The underground storage tank was operated to fuel Bakersfield College's maintenance department vehicles. 2.2 Background Bakersfield College contracted with Franzen Hill of Tulare, California to remove the underground fuel storage tank, dispenser, and associated product pipeline at the site. On May 2, 1992, Franzen Hill removed the tank, dispenser, and associated product pipeline. The tank was removed under permit with the City of Bakersfield .Fire Department; Hazardous Materials Division. 1 I Bakersfield College 2 May 21, 1992 I I I I I I I I I I I I I I I I I Franzen Hill contracted with Earth Systems Environmental to provide an' -environmental technician to collect soil samples at the direction of Mr. Joe DunWoody with the City of Bakersfield Fire Department, Hazardous Materials Division. 3.0 SOIL SAMPLING One s0il sample (TH-l) was collected from beneath the center of the the former tank location at a depth of 11 feet below surface grade. Two soil samples (TH-2, and TH-3 ) were collected' from beneath the former product pipeline at a depth of 6 and 4 feet below surface grade, .respectively. One soil sample (TH-4) was collected from beneath the former dispenser at a depth of 4 feet below surface grade (Figure 2). The samples were collected from the backhoe bucket immediately after soil excavation and stored in 2" brass tubes, sealed with teflonTM liners and end caps. The samples were then labeled, handled and transported according to the United States Environmental .Protection Agency (USEPA) protocol to a State of California Department of Health Services' (DOHS) certified laboratory. Sample identification and chain-of-custody procedures were utilized for the samples to ensure sample integrity and to document' sample possession from the time of collection to its ultimate destination. The sample label identified the job number, sampler, date and time of collection and sample number unique to the sample. All sampling equipment was washed with TSPTM (tri-sodium phosphate) cleanser, pre-rinsed with tap water and a final rinse of de-ionized water prior to sampling. 4.0 ANALYTICAL METHODS The soil samples designated for chemical analysis were submitted to B C Laboratories in Bakersfield, a State of California Department of Health Services (DOHS) certified laboratory.. Appendix A presents copies of the analytical results and chain-of- custody documents. The soil samples were analyzed for Total Purgeable Hydrocarbons (TPH) as gasoline 'using the California DOHS LUFT Method, and for the gasoline constituent volatile aromatics, benzene, toluene, ethylbenzene, and total xylenes (BTEX) using USEPA Test Method 8020: EB-8191-1 9205-E053.RPT I I Bakersfield College 3 May 21, 1992 I I I I I I I I I I I I I I I I I 5.0 RESULTS OF SOIL SAMPLING Total Purgeable Hydrocarbons (TPH) as gasoline and the gasoline constituent volatile aromatics were not .detected at or above the detection limit in the sample TH-1 analyzed from beneath the former underground storage tank. However, TPH as gasoline were detected at concentrations of 21 mg/kg, and 4,000 mg,kg from'the samples. TH-2 and TH-3. TH-2 was positioned beneath the product pipeline on the side of the excavation at a depth of 6 feet, where there was a visual indication questioning the integrity of the tank. TH-3 was positioned beneath the product pipeline run. TPH as gasoline was detected at concentrations of 1,000 mg/kg in sample TH-4 from beneath the former dispenser. Volatile aromatic compounds were detected in minor concentrations in samples TH-2 and TH-3, but were detected in significant concentrations in TH-4 with benzene detected at 2 rog/kg. Table I presents a summary of the analytical results for TPH as gasoline, and the gasoline constituent volatile aromatics in the four soil samples: TABLE 1.

Action Levels were calculated using the LUFT methodology by multiplying the most stringent current federal or state water quality standards by a factor of 1000 to account for attenuation due to soil composition and distance from groundwater. 6.0 EXCAVATION PIT BACKFILLING Franzen Hill backfilled the pit with the over excavated soil and imported fill, compacted the backfill, and returned the site to surface grade. EB-8191-1 9205-E053.RPT I I Bakersfield College 4 May 21, 1992' I I I I I I I I I I I I i I I I I 7.0 CONCLUSIONS Based on the soil sampling and analysis, detectable concentrations of TPH as gagoline and the gasoline constituent volatile aromatics were not present in the soil samples collected from beneath the former underground fuel storage tank. However, gasoline-hydrocarbons' constituents were detected in the soil samples, from beneath the-product pipeline and dispenser. Additional site characterization, and possible remedial activities is likely to be required by the City of Bakersfield Fire Department, Hazardous Materials Division. 8.0 CLOSURE This report has been prepared for the exclusive use of Franzen Hill, and Bakersfield College as it pertains to the referenced property in Bakersfield, California. The results contained in each verbal or' written report were based upon the information acquired during the assessment. It is possible that. variations could exist beyond points explored during the course of the investigation. Also~ changes in conditions found could occur at some time in the future due to contaminant migration, variations in rainfall, temperature, and/or other factors not apparent at the time of the field investigation. The services performed by ESE were conducted in a manner consistent with: the level of care-and skill ordinarily exercised by members of our profession currently practicing under simiIar conditions in the state of California. No other warranty is expressed or implied. EB-8191-1 9205-E053.RPT Bakersfield College 5 May 21, 1992 Thank you for this Opportunity to have been of service.
