Total petroleum hydrocarbons as gasoline (TPH/G), and benzene, tOluene, ethYlbenzene, and total xylenes (BTEX) were detected in several soil samples collected from the excavation bottom and sidewalls. The greatest concentrations were detected in samples collected from beneath the southern end of the center tank (ibid.). In January, 1993, EMCON drilled and sampled four soil borings in the former location of the liST's (EMCON, 1992b; 1993a). The borings were drilled to depths of 36.5, 41, 43, and 44 'feet. Ground water, reported to be at a dePth of approximately 200 feet beneath the site, was not encountered. Hydrocarbons were detected in two soil samples collected from 'EMCON's soil borings (EMCON, 1993a). Total xylenes were detected at a concentration of 0.016 milligrams per kilogram (rog/kg) in a soil sample collected from a depth of 20 feet beneath the former pump island, about 10 feet south of the former tank locations. Benzene and ethylbenzene were detected at concentrations of 0.1 and 0.2 mg/kg, respectively; TPH/G was detected at a concentration of 16 mg/kg; and organic lead was detected at a concentration of 2.2 mg/kg in a soil sample collected from a depth of 5 feet at a location approximately 10 feet west of the former tank locations (ibid.). In a February 4, 1993 letter, the Bakersfield City Fire Department (BCFD) concluded that further assessment was required to define the vertical extent of impact which had been detected during the UST removal. During the UST removal, 3,300 mg/kg TPH/G had been detected in a soil sample collected from a depth of 17 feet beneath the southern end of the center UST (EMCON, 1992a). During EMCON's January 1993 investigation, hydrocarbons were not detected in a soil sample collected from a depth of 20 feet in this same area (EMCON, 1993a). In the opinion of the BCFD, a soil sample collected from 3 feet below highly impacted soil should have contained detectable hydrocarbon concentrations. The BCFD concluded that borings drilled for the January 1993 investigation apparently failed to intersect impacted soils previously detected. STHLND-06-93-56 1 Copyright 1994 Kleinfelder, Inc. EMCON prepared a workplan to perform additional investigation (EMCON, 1993b). The I .__plan consisted of drilling a sampling two additional soil .borings to further assess the vertical extent of impacted soil. The workplan was approved by the BCFD on March 18, 1993, and i again on October 11, 1993. Kleinfelder performed the additional investigation, as approved, in December, 1993. The investigation methods and findings are described in the following text. I I I I I I I 1 I I I I 1 I STHLND-06-93-56 2 Copyright 1994 Kleinfelder, Inc. 1 kl~ KLEI~FELDER 2 SCOPE OF WORK Kleinfelder's work scope was described in EMCON's March 12, 1993 workplan (EMCON, 1993b). Kleinfelder performed this investigation in general accordance with guidelines described in the January 22, 1991 "Tri-Regional Board Staff Recommendations for Preliminary Evaluation and Investigation of Underground Tanks Sites". Kleinfelder's field activities were performed in accordance with our standard protocols, presented in Appendix B. 2.1 SOIL BORINGS AND SOIL SAMPLING Kleinfelder drilled two soil borings in the area where the greatest hydrocarbon concentrations had been detected during the 1992 UST removal (Plate 2). One of the borings, SB-1, was drilled in the location where the greatest hydrocarbon concentrations had been detected during the 1992 UST removal (EMCON, 1992a). The borings were drilled to depths of 41.5 and 42 feet, and soil samples were collected at 5- foot intervals. The samples were examined by Kleinfelder's geologist for preparing lithologic logs, and preserved for potential chemical analyses. The soil boring logs are in Appendix C. 2.2 LABORATORY ANALYSES Samples collected from depths of 19, 23.5, 31, 36, and 40 feet from boring SB-1, and from depths of 11. 25, 36, and 41 feet from boring SB-2 were chemically analyzed by Pace Incorporated (Pace) laboratory. Samples were analyzed for TPH/G using EPA modified method 8015, and for BTEX using EPA modified method 8020. Each of the samples except one was analyzed for organic lead, using California Department of Health Services method 338. One of the samples, the 11-foot depth sample from SB-2, was not analyzed for organic lead, but was analyzed for TPH/diesel using EPA method 3550/8015. Pace is certified by the California Department of Health Services to perform these analyses. I I i STHLND-06-93-56 3 Copyright 1994 Kleinfelder, Inc. I k~ KLEINFELDER I 3 LABORATORY ANALYTICAL RESULTS I I TPH/G and BTEX were not detected in the analyzed soil samples (Table 1). The analysis for TPH/D detected an unknown heavy hydrocarbon at a concentration of 18 mg/kg; the --laboratory reported that the detected compound did not appear to be diesel. Organic lead was I detected at concentrations of 0.4 rog/kg and less in samples from depths of 31 and 36 feet in SB-1, and in samples from depths of 25 and 41 feet in SB-2. Laboratory analytical reports are I in Appendix D. I I I I I I I I I I I. 1 I STHLND-06-93-56 4 Copyright 1994 Kleinfelder, Inc.

An unknown heavy hydrocarbon was detected in the 11-foot depth sample from SB- 2 at a concentration not li,kely to be of regulatory concern (18 mg/kg). Organic lead was I .._detected in two samples from each boring at concentrations we~ow the California Code of Regulations, Title 22, Total Threshold Limit Concentration o~mg/kg. On the basis of these analytical results, and the results of EMCON's previous investigation (EMCON, 1993a), soils in the former LIST location do not presently appear to contain I hydrocarbons. Apparently hydrocarbon compounds detected in 1992 (EMCON, 1992a) were very limited in extent. Kleinfelder recommends no further action, and requests site closure.

The procedures described herein are Iintended to be of general use. As work progresses, appropriate revisions may be made at the discretion of the project manager. I 2 PROCEDURES FOR DRILLING AND SOIL SAMPLING I 2.1 Permitting I Kleinfelder will prepare applications for appropriate permits, unless otherwise instructed by the client. Copies of signed permits will be on-site during drilling operations, and will be Iavailable for inspection by appropriate agencies. I 2.2 Equipment Cleaning i Drilling equipment will be thoroughly steam-cleaned prior to arriving on-site to prevent the introduction of contamination from off-site. Clean equipment will be stored in a clean location when not in use. Hydrocarbon based lubricants will not be used on drilling equipment. I Kleinfelder recommends that food grade-solid, vegetable shortening, or a Teflonm based lubricant be used. Equipment will be steam-cleaned on-site, and will be cleaned only in I designated prior to reuse. areas, 2.3 Sampler Cleaning Soil samplers will be disassembled, washed with a solution containing TSP or non-phosphate detergent, or steam-cleaned, rinsed with steam distilled water, and air-dried immediately prior to use. Samples will be lined with similarly cleaned and dried brass tubes, and reassembled for use. I i.... STHLND-06-93 (App&Prot-002-91-007) B-1 Copyright 1994 Kleinfelder, Inc. ~1~ KLEINFELDER 2.4 Drilling The drilling method used will be determined based upon the material to be drilled, depth and diameter of the boring, sampling requirements, site access, and other site-specific conditions. Drilling methods which will be used is the hollow-stem auger method. This method employes the use of 6-inch hollow-stem auger advance by a truck mounted drill rig. The subsurface stratigraphy will be interpreted by observing the materials recovered during drilling, and by sampling undisturbed soils. Soils will generally be sampled at a minimum of once per each 5 feet drilled, or at noticeable changes in lithology, until ground water is encountered. Sampling intervals may vary depending upon project requirements. Soils will be sampled using a California-modified sampler containing cleaned brass liners, or a standard pen. etration sampler. Lithologic logging of the boring is discussed in Section 2.5, and sampling is discussed further in Section 3.1. Boring depths will be based upon the nature and extent of the materials encountered, and upon project requirements. 2.5 Preparation of Boring Logs The Kleinfelder field geologist will lithologically log the borings during drilling. The geologist and the drilling operator will discuss changes in material penetrated by the drill, changes in drilling conditions, hydraulic pressure, drilling action, and drilling fluid circulation rate, and the geologist will record such changes by time and depth. The geologist will evaluate the relative moisture content of the samples and note zones that produce water. I 2.6 Sealing of Boring IBoreholes will be abandoned by backfilling to the surface with soil cuttings, or with a bentonite cement grout. I I I STHI. aND-06-93-56 I (App&Prot-002-91-007) B-2 Copyright 1994 Kleinfelder, Inc. I 3 SOIL SAMPLING 3.1 Sampling Interval in Borings I Soil samples will be taken at 5-foot intervals, or as necessary, based upon project-specific requirements. Soils will be sampled by driving a California-modified sampler 18 inches I beyond the bottom of the drill bit. The sampler will be driven using a 140-pound slide hammer. The number of blows necessary to drive the sampler each 6 inches will be recorded Ito help evaluate soil consistency. I The sampler will contain three brass liners. Soils collected in the bottom liner may be labeled, sealed, and preserved in an ice-cooled container for potential laboratory analyses. Selected i soil samples may be delivered under a chain-Of-custody record to a State-certified laboratory for chemical analyses. Soils. which are collected in the upper and middle liners from the sampler may be extruded in the field, and examined by Kleinfelder's geologist to help provide I detailed lithologic information. I 3.2 Qualitative Field Screening I An organic vapor analyzer, using a flame ionization detector or a photo ionization detector will be used to provide a qualitative screening of each soil sample collected during drilling. The i field screening procedure consists of sealing a soil sample in a clean glass jar, allowing the sample' to equilibrate for 5 to 15 minutes, and scanning the headspace in the jar for vapors. The screening readings will be noted on the boring log and/or on the daily field log. I 3.4 Sample Preservation I The sample selected for chemical or physical testing will be sealed in the brass liner in the Ifield. TeflonTM sheeting covers will be placed on the ends of the liner directly on the exposed soils, and held in place by clean plastic caps. Sealed soil samples will be labelled and placed Iin a covered ice-cooled container. I I i STHLND-06-93-56 (App&Prot-002-91-007) B-3 Copyright 1994 Kleinfelder, Inc. 4 SAMPLE HANDLING I Sample containers will not be opened, except by laboratory personnel who will perform the ichemical analyses. Soil samples will be analyzed by a laboratory certified by the State of --California, Department of Health Services. Requests for sample analyses will be made in writing and will be included as part of the chain-of-custody record. I 4.1 Custody Seal I If it is necessary for samples or sample chests to leave the immediate control of the sampler I prior to being delivered to the laboratory, a custody seal will be placed on each sample container and/or sample chest to discourage tampering during' transportation. The custody seal will contain the sampler's signature, and the date and time seal was emplaced. I 4.2 Chain of Custody Procedures I In order to document and trace sample possession from time of collection to time of analysis, a I chain-of-custody record will be filled out by the sampler, and will accompany the sample through the laboratory analyses. The completed chain-of-custody record will accompany the I final laboratory analytical report. Information contained on the duplicate, carbonless chain-of-custody form will include: I o date and time the sample was taken; I o sample number and the number of sample containers; o . analyses required; I o remarks, including preservatives added and any special conditions; and 'o container number in which sample has been packaged. I Blank space on the chain-of-custody record between last sample number listed and signatures i at the bottom of the sheet will be lined out.
