The construction operation included excavation, removal of the hydrocarbon impacted soil, placement as well as compaction of the backfill of the excavated area (created as a result of the removal of the soil), and resurfacing with concrete (Figure 2). The placement and compaction of the backfill were performed by Dargahi & Associates, a licensed contractor in state of California (#663798), under the observation and testing of Hydrologue Consulting Engineers and Geologists. All the operations were performed using a Bobcat Loader, and a Mechanical Loader. l I 55 East Green Street · Pasadena, CA 91106 ' · Tel. (818) 585 - 9696 · Fax (818) 585 - 0046 Caldwell International Inc. page 2 of 4 Project No.: 1229-01 LABORATORY TESTING Imported clean soil was used as backfill material. The backfill material consisted of light brown slightly silty sand with some fine gravel similar in nature to the existing on-site artificial material. The maximum dry density and optimum moisture content of the backfill material was determined in accordance with the ASTM D-1557-91 Method by hydrologue who performed on-site compaction testing. The results are as follows: Maximum Dry Density Optimum Moisture Content 121 pounds per cubic foot 10.5 percent SITE PREPARATION and FILL PLACEMENT Prior to placement of fill material, construction debris, deleterious materials, and loose soils were removed to expose the firm natural ground. The fill was then placed in 6 to 8 inches lifts, and compacted to at least 90 percent relative compaction. Relative compaction is defined as the ratio of field dry density to laboratory maximum dry density. A total of nine (9) field dry density tests were performed in accordance with ASTM-1556, the Sand Cone Method. The test results are presented in the following table: hydrologue, Inc.

I I I I I I I I I I I I '1 I I I I I 1.0 INTRODUCTION This report presents the results of soil sampling and analysis associated with the soil remedial operation in a single family residence located at 1324 Ensley Drive, Bakersfield, California (Site, Figure 1). The soil at the subject Site had been impacted by gasoline leaked from a vehicle parked inside the garage. The purpose of the soil remedial operation was to remove the hydrocarbon impacted soil from the subject Site. 1.1 Background Based on the documents provided to hydrologue Inc. ("Hydrologue") by Ron Phares & Co (RPC), in August 1995 an accidental release of approximately 22 gallons of gasoline fuel occurred at the above referenced Site. The RPC insurance claim report indicated that gasoline leaked from a vehicle parked inside the house garage at the Site, while the property owner, Mr. Jeff Andrew, was away on vacation. The gasoline spill occurred near the center area of the attached garage which includes three parking spaces (Figure 2). Prior to the incident, the vehicle had been taken to Sanghera Autohaus, Inc. for repairs where the fuel pump was replaced. The gasoline reportedly percolated beneath the concrete slab through the expansion joints and existing crack in the concrete slab. The property owner contacted EPS Engineering Services, Inc. (EPS) and requested EPS to conduct a Site inspection at his residence to determine the extent of soil contamination. On August 18, 1995, EPS performed a Site inspection and investigated the potential levels of soil contamination and recommended for soil remediation. The proposed remediation process consisted of excavation and aeration of the excavated material for decontamination prior to disposal. On August 18 and 29, 1995 and September 1, 1995, EPS conducted air monitoring using an Organic Vapor Analyzer (OVA)/FID to determine the presence of Volatile Organic Compounds (VOCs) inside the house. The air monitoring results showed that concentrations of VOCs were detected ranging from 25 to 250 parts per million (ppm) in the garage. Concentrations of VOCs ranging from 2 to 30 ppm were detected inside the house (EPS report, dated September 8, 1995). From September 18 through September 26, 1995, EPS collected several soil samples from the surface of the impacted area down to approximately 20 inches below ground surface (bgs) using a hand auger. Analytical results of collected soil samples showed that the largest concentrations of Total Petroleum Hydrocarbons as Gasoline (TPH-G) was 1,543.5 p.g/kg at 10 inches bgs (Table 1). Only two soil samples were analyzed for benzene, toluene, ethylbenzene, and total xylenes (BTEX). The largest concentration of benzene was 62 gg/kg at 8 inches bgs (Table 1). Chain-of-Custody Record Forms were not available to Hydrologue and are not included in this hydrologue, Inc. I I I I Report of Soil Remediation 1324 Ensley Drive, Bakersfield, California Project No.: 1229-01 report. The laboratory analytical results of soil samples are shown in Table 1 as prepared by EPS 1.2 Hydrologue Field Investigation Hydrologue was later retained by Caldwell International Inc. and its representative, RPS, to perform a Site observation on October 9, 1995. Present at the Site were Patrick Mbaba of EPS and the residence owner. According to EPS, the garage and the house were aerated after the discovery of the gasoline leak, and the residents were asked to vacate the house and to live in another home. On or about October 1, 1995, the existing concrete slab had been demolished and removed in preparation for soil remediation, and the soil beneath the concrete slab was aerated. i I I I I Hydrologue dug out three areas XA, XB and XC near the center of the garage to approximately 20 inches bgs to determine the presence of hydrocarbons in the soil (Figure 2). Only location XA showed a slight hydrocarbon odor (Figure 2). Soil at each location was collected and sealed in a plastic bag and was placed under the sun to enhance volatilization of VOCs emanating from the soil. A Photovac Microtip Model 1000 Photo Ionization Detector (PID) was then used to detect the presence of VOCs. There were no VOCs detected by the PID from any of the soil samples examined at the Site, even from the area with slight hydrocarbon odor. Hydrologue was then retained by Caldwell International Inc. to carry out the EPS recommended soil remediation at the Site. After evaluating all available information provided by EPS on the lateral and vertical extent of soil impacted by gasoline hydrocarbons, Hydrologue proceeded with the recommended soil remediation. I I I I I I I 2.0 Soil Remedial Operation 2.1 Soil Excavation The soil excavation and sampling program was conducted in conformance with the regulatory specifications of Cal/OSHA requirements. The Office of Environmental Services in the City of Bakersfield, and the San Joaquin Valley Unified Air Pollution Control District, Southern Region, were contacted and notified regarding the soil remedial operation. A Health and Safety Plan was also prepared and followed during the field activities. On November 14, 1995, soil remedial operation started, and soil in areas where the concrete slab was previously demolished was excavated. Based on the available information on the extent of hydrocarbon impacted soil, the depth of excavation was determined as approximately two (2) feet bgs. All excavation activities were carried out by Dargahi & Associates, a licensed contractor in the state of California (#663798). Upon removal of the soil from the excavation area, the hydrocarbon impacted soil was transported to CleanSoils California, Inc. (CSC) in Bakersfield, California for treatment and recycling. I hydrologue, Inc. I I :1 ! I I I I I I I I l I I I I Report of Soil Remediation 1324 Ensley Drive, Bakersfield, California Project No.: 1229-01 Soil excavation continued until November 15, 1995, when additional excavation was performed on the southern segment of the garage area and in the driveway area outside the garage (Figure 2). The additional soil excavation was performed in areas where trace levels of hydrocarbons were detected in the corresponding soil samples collected and analyzed. Then, additional soil samples were collected and analyzed to confirm that hydrocarbon impacted soil has been removed. Upon completion of excavation actix;ities, the excavation area was backfilled with clean soil, the soil was compacted, and a compaction test was subsequently performed to confirm adequate compaction. All compaction test activities were carded out by Hydrologue geologist under the direct supervision of a California Registered Geotechnical Engineer (R.G.E). 2.2 Soil Sampling Based on the original scope of work, two soil samples had been planned to be collected and analyzed. Because of field observations by Hydrologue geologist who suspected possibility of the presence of trace concentrations of gasoline hydrocarbons in the soil, additional soil samples were collected for analysis. One (1) soil sample was collected from each wall of excavation (SSSW-1, SSWW-1, SSNW-1, SSEW-1, Figure 2), and one (1) soil sample SSOA-1 was collected from the excavation in the driveway. Three (3) soil samples SPS-1, through SPS-3 were collected from the soil stockpile prior to transportation for off-site disposal. Based on the laboratory results of collected samples, further excavation was conducted on the southern portion of the garage and the driveway. Four (4) confirmation soil samples (SSOA-2, SSOA-3, SSBS-2, SSSW-2, Figure 2) were collected after completion of additional excavation. Two (2) soil samples SSCS-1, SSCS-2 were collected from the imported clean soil to ensure lack of hydrocarbon contamination prior to backfilling. Furthermore, Hydrologue's PID probe was utilized on the stockpiled soil to determine if volatile hydrocarbon vapors were emanating directly from the soil. There were no detectable concentrations of VOCs as measured by the PID. No visual or olfactory evidence of hydrocarbon was noted by Hydrologue. Hydrologue geologist utilized a clean hand trowel to collect the soil samples from the excavation and stockpile at approximately 2 feet depth inside the soil stockpile. The samples were placed in 2.5-inch diameter brass rings covered with aluminum foil and plastic cap on one end. After sample recovery, the open end of each container was covered with aluminum foil and plastic caps taped over the ends, then sealed in Ziploc plastic bags. Prior to use, all sampling tools and implements were washed in a non-phosphate cleanser solution, rinsed with tap water and then distilled water. The soil samples were sealed, labeled with the sample identifications, dated with time of sampling and Hydrologue project number, and were immediately placed into a chilled ice chest containing frozen blue and/or crushed ice. The samples were logged on chain-of-custody record forms (see Appendix B). I I hydrologue, Inc. Report of Soil Remediation 1324 Ensley Drive, Bakersfield, California Project No.: 1229-01 2.3 Soil Treatment Immediately after excavation, the hydrocarbon impacted soil was transported off-site and was delivered to the CSC facility located in Bakersfield, California for treatment. CSC facility is equipped with Low Temperature Thermal Desorption system that removes the volatile hydrocarbon vapors from the impacted soil by pre-heating and then destroys the removed hydrocarbons by thermal oxidation. Appendix C contains the manifest and destruction certificate for the treatment of 43.02 tons of soil removed from the Site. 2.4 Soil Compaction On November 15, 1995, the excavation area was backfilled and compacted. A soil compaction report dated December 19, 1995 was prepared by Hydrologue and was submitted to Caldwell International Incorporated. 2.5 Slab-on-Grade (Concrete Resurfacing) On November 16, 1995, the backfilled area was prepared for concrete work. The approximate slab thickness of five (5) to seven (7) inches, size of reinforcing wire mesh, number, and placement of the expansion joints were chosen to match the existing concrete slab. The concrete slab was underlain by a 6-mil visqueen liner placed over the compacted fill. One (1) inch of clean sand was placed between the concrete slab and the visqueen liner to aid in curing. 2.6 Air Monitoring During excavation activities, Hydrologue monitored vapor concentrations in the ambient air around the excavation area using a handheld Photovac Microtip Photoionizer Detector (PID) Model MP-1000 calibrated against an isobutene gas standard. There were no concentrations of volatile hydrocarbons detected with the PID monitor. No visual or olfactory evidence of hydrocarbon contamination was noted by Hydrologue. On November 16, 1995, Hydrologue conducted air monitoring inside the house using the PID probe, and there were no VOCs detected. 2.7 House Cleaning Prior to the start of soil remedial operation, the property owner had complained about the generated dust as a result of previous concrete removal activities where the dust had spread inside the house. The property owner requested house cleaning services upon completion of the 4 hydrologue, Inc. '1 I I I I I ! I I I I I I I 'i I Report of Soil Remediation 1324 Ensley Drive, Bakersfield, California Project No.: 1229-01 soil remedial operation. Hydrologue hired a local agency in the City of Bakersfield for all necessary .cleaning as requested and approved by the property owner. Additionally prior to excavation activities, the garage doorway leading to the house interior was sealed off with visqueen liner and tape to prevent dust from entering the house. 3.0 ANALYTICAL RESULTS All collected soil samples were delivered for analytical testing to BC Laboratories, Inc. of Bakersfield, a state of California certified laboratory. BC Laboratories is certified for all tests completed as part of this soil remedial operation (Appendix D). Each soil sample was analyzed for TPH-G using Modified EPA Method 8015, and BTEX by EPA Method 8020. Additionally, one soil sample was also analyzed for CAM Metals by EPA Method SW-846, as requested by the soil treatment/recycling facility (CSC). Soil samples were analyzed for gasoline hydrocarbons on a "Rush Order" request from the' laboratory with a two-hour turnaround time. The quick turnaround time was necessary for the on-site Hydrologue geologist to determine the locations where further hydrocarbon impacted soil had to be excavated. The analytical results of the soil samples are shown in Table 2, and the laboratory reports are presented in Appendix A. TPH-G, Benzene, and total Xylenes were not detected (ND) in any of the soil samples analyzed (Table 2). Sample SSOA-1 contained trace concentrations of Toluene, and Ethylbenzene at 0.009 rog/kg and 0.006 mg/kg, respectively (Table 2). After additional soil excavation at the location of SSOA-1, a confirmation soil sample SSOA-2 was collected at the bottom of excavation area. There was no Ethylbenzene, and only trace concentration of Toluene (0.01 mg/kg) below the Maximum Contaminant Level (MCL) for drinking water was detected in SSOA-2 (Table 2). After further soil excavation in the area arotmd SSOA-2, another confirmation soil sample SSOA-3 was collected at the bottom of the final excavation. There were no TPH-G and BTEX detected in the soil sample SSOA-3 (Table 2). Samples SSSW-1 and SSBS-1 contained concentrations of Toluene at 0.017 mg/kg and 0.021 rog/kg, respectively (Table 2). After additional excavation, the confirmation samples SSSWo2 and SSBS-2 contained no TPH-G and BTEX. Stockpile soil sample SPS-1 contained Toluene at 0.025 mg&g, SPS-2 contained Toluene and Ethylbenzene at 0.047 and 0.006 mg/kg, respectively, and there were no TPH-G and BTEX concentrations detected in SP-3. Two soil samples SSCS-1 and SSCS-2 were collected from the imported clean soil for backfilling, and there were no TPH-G and BTEX detected in the soil samples. hydrologue, Inc, I I I I I I I I I I I '1 I I I I I Report of Soil Remediation 1324 Ensley Drive, Bakersfield, California Project No.: 1229-01 4.0 CONCLUSIONS and RECOMMENDATION Based on the information contained herein, it is Hydrologue's opinion that the Site assessment activities have been completed.
