(SEI) following the completion of field work and the receipt of soil sample analytical results at the Country Club Cleaners located at 4800 White Lane in Bakersfield, CA. (site). This report includes a description of the fieldwork conducted, soil boring locations, soil sample analytical results, a discussion of results, a risk assessment and recommendations for the site. BACKGROUND Country Club Cleaners has occupied this site since the early 1980's conducting dry cleaning services to the public. Prior to the early 1980's the site was vacant land or agricultural related. To assess the depth and lateral extent of chlorinated solvents in the soil in the area of the dry cleaning machine and other potential source areas, SEI advanced a total of 10 soil borings to a depth of 5' bgs. at the site. PHASE II ENVIRONMENTAL SITE ASSESSMENT Field Work Assessment of Soil Conditions (10 Soil Borings to depth of 5') SEI advanced 7 soil borings (Bl to B7) within the building area to a depth of 5' below ground surface (bgs.) on April 20,2001 and an additional 3 soil borings (B-8 to B-I0) on June 11,2001 at locations shown on the attached Plot Plan (Plate 2). Borings B 1 to B4 were placed within 2' of the dry cleaning machine on all 4 sides. Boring B5 was placed near the back door, boring B-6 was adjacent to a floor drain and the boiler and B7 was adjacent to an old Tetrachloroethene (PCE) filtering machine within the boiler room. Boring B-8 was located 10' west of boring B-2, boring B-9 was located approximately 6' northeast of boring Bl, and boring B-I0 was located approximately 5' south of boring B-3 to better define the PCE plume in these areas.

Bakersfield. CA. SOILS ENGINEERING, INC. File No. 01-9597 July 13, 2001 Paee 2 samples were collected at depths of 1', 3' and 5' bgs. at each boring location utilizing a hand auger and a core sampler. A 5' bgs. soil sample was not possible at boring B-9 due to an obstruction at approximately 3' bgs.. The borings were advanced with a hand auger after the removal of a small portion of concrete (4" -diameter hole) at the surface. Soil samples were collected with a core sampler containing a 2.5" diameter brass sleeve at depths of 1', 3' and 5' after the hand auger had been removed from the borehole at the sampling depths. The cort;; sampler was advanced approximately 6-inches into the undisturbed soil to collect the soil sample by hand auguring. After retrieval the soil sample was sealed with Teflon-lined Caps, labeled and placed into an iced cooler. The soil type was documented along with any staining, hydrocarbon vapor readings and odor on a boring log. The hand auger and core sampler were decontaminated (washing and rinsing) between each sampling event to prevent cross-contamination. Soil cuttings were placed back into the borehole and capped with concrete to match existing grade. Analytical Testing of Soil Samples Selected soil samples (total of 29) were analyzed for halogenated volatile organics by EP A Method 802lB at Positive Lab Service in Los Angeles, CA. a State certified analytical laboratory. The soil samples were transported in a sealed cooler with blue ice and completed chain of custody documents by overnight courier. FINDINGS Description of Soil Type A California registered geologist (RG) described the soil types in accordance with the Unified Soil Classification System (USCS) as the borings were advanced. In general the top 2' of each soil boring was predominately silty sand (SM) which was dark yellowish brown, soft, moist, with no staining or odor. The soil from 2' to 4' bgs. generally consisted of clayey silt (ML), which was underlain by poorly to well graded sands (SP or SW), which were medium yellowish brown, very fine to coarse grained, medium dense, damp, with no staining or odor. Clay (CL) was encountered in the bottom of borings Bl, B3, and B4. Hydrocarbon vapors were detected in the soil samples ranging from 75 ppm to 150 ppm with the highest reading in the 3' bgs. samples of borings B3 and B4. Slight odor and possible staining was noticed in the 3' bgs. samples from borings B8 and B9. See attached boring logs B 1 to B 1 0 for more detail in Appendix B. Analytical Results of Soil Samples A total of 29 soil samples were analyzed for halogenated volatile organics by EP A Method 802lB at Positive Lab Services in Los Angeles, CA.. The analytical results indicate significant concentrations of the dry cleaning solvent Tetrachloroethene, also known as PCE, in the top 4 feet at the site in the vicinity of the dry cleaning machine (borings B 1 to B4 and B9). No significant PCE concentrations were reported in any of the soil samples from borings B5 to B7. The highest PCE concentration reported in this investigation was 7600 ppb at boring B9 at a I I I I I I I I I I I I I I I I I I I Phase II Site Assessment Report Country Club Cleaners 4800 White Lane. Bakersfield. CA. SOILS ENGINEERING, INC. File No. 01-9597 July 13, 2001 Page 3 depth of l' bgs.. Other soil samples with PCE concentrations reported above 100 ppb were; B I- l' (1100 ppb), Bl-3' (6900 ppb), B2-3' (1700 ppb), B3-l' (350 ppb), B3-3' (1300 ppb), B4-l' (120 ppb), B4-3' (3900 ppb), B8-3' (160 ppb), B9-3' (7500 ppb), and BlO-3' (310 ppb). No other chlorinated solvents were reported in any of the soil samples, except for Trichloroethene (TCE) at 25 ppb in soil sample B8-3'. Reported constituents are presented on Table 1 and complete analytical reports are attached as Appendix A. RISK ASSESSMENT A Risk Assessment is presented below which suggests remedial cleanup levels for the site and evaluates current and potential risk and hazards to workers and the environment at the site. A risk assessment was performed by SEI utílizing the program Risk Based Corrective Action (RBCA) Tool Kit for Chemical Releases by GSI. The 95% Upper Confidence Level (VCL) of the reported concentration of PCE above 100 ppb in the soil (4500 ppb) was inputted along with the worst case soil type (sand), current depth to groundwater (170 feet), and other pertinent site- specific information to determine an appropriate cleanup level for this site. The calculated RBCA cleanup level concentration for PCE in soil is lower than what is currently in-place at the site. The cleanup level for PCE in soil at a commercial site is 1.9 parts per million (ppm) and the 95% UCL at the site is 4.5 ppm. The exposure pathways that come close to exceeding the target risk (1 x 10-5) or hazard (1.0) for a commercial site is the indoor air pathway, which has a cumulative risk of 1.9 x 10-6 and the soil exposure pathway which has a cumulative risk of 2.4 x 10-6. No pathways come close to exceeding the hazard index of 1.0 for the site. According to the attached risk calculations groundwater does not appear to be threatened by this release of PCE at a current depth of 170 feet beneath the site. Since this is a commercial site it appears that the risk and hazard to the occupants/workers and to the groundwater beneath the site is acceptable, if the soil is left: in-place. See attached RBCA Tables and calculations attached as Appendix C for more detail. CONCLUSIONS Based on the results of field observations and analytical results SEI presents the following conclusions for this site: 1) In general, the top 2' of each soil boring was predominately silty sand (SM), which is underlain by clayey silt (ML) from 2' to 4' and then poorly to well graded sands (SP or SW) to a depth of 5' bgs.. Clay (CL) was encountered at 5' bgs. in 4 of the 10 borings. No significant staining or odor was noticed in the soil samples upon collection. Only minor odor and possible staining was noticed in soil samples B8-3' and B9-3'. Hydrocarbon vapors were detected highest in the 3' bgs. soil samples from borings B3 and B4 at 150 ppm.

File No. 01-9597 July 13, 2001 Pa2e 4 2) Concentrations of the dry cleaning solvent PCE above 100 ppb have been reported at soil boring locations Bl, B2, B3, B4, B8, B9 and BlO at the site. The highest PCE concentration reported in any of the soil samples analyzed was 7600 ppb at a depth of 1 ' at boring B9. Other significant PCE concentrations reported were 7500 ppb (B9-3'), 6900 ppb (BI-3') and 3900 ppb (B4-3'). None of the 5' deep soil samples had any PCE concentrations reported above 100 ppb, indicating that the dry cleaning solvents are restricted to the top 4' (within the silty zone) in the general area of the dry cleaning machine. The highest PCE concentrations appear to be on the north side of the dry cleaning machine in the areas of borings B 1 and B9 where previous PCE releases may have occurred. 3) No significant PCE concentrations were reported at soil boring locations B5, B6 or B7. A significant decrease in PCE concentrations were reported in borings B8 and BI0, which were step-outs for borings B2 and B3, respectively. 4) The dry cleaning machine, along with buckets or drums containing PCE are the likely source of the PCE Plume. Periodic spills or leaks of PCE on the concrete surface would account for the PCE plume discovered beneath the site in the soil. The estimated solvent plume with concentrations of PCE greater than 100 ppb is approximately 120 cubic yards with a vertical depth of 4' bgs. and a lateral extent of approximately 32' by 25'. The lateral extent has not been established to the north-northeast, but appears to be less than 12' radius from the dry cleaning machine to the west, east and south. The plume appears to continue off-site to the north-northeast beneath the adjoining tenant. See Plate 3 for the approximate PCE plume in the soil beneath the site. 5) A risk based corrective action assessment indicates that the current concentrations of chlorinated solvents in the soil are above the acceptable cleanup levels (1.9 ppm PCE) for a commercial site, although the EP A's Preliminary Remediation Goals (PRG's) for PCE in soil at an industrial site is 19 ppm. The maximum PCE concentration in soil detected at the site was 7.6 ppm, which is less than the EPA's PRG. Based on the risk assessment calculations the cumulative indoor air risk (1.9 x 10-6) and soil exposure risk (2.4 x 10-6) are both within acceptable limits (1 x 10-5) for a commercial site. The risk to the groundwater appears to be acceptable at a current depth of 170' bgs.. RECOMMENDATIONS 1) SEI recommends that the suspected source(s) of the PCE leaks or spills be prevented by installing secondary containment beneath the dry cleaning machine and any buckets or drums ofPCE liquid at the site. 2) Resealing the concrete surface area beneath and adjacent to the dry cleaning machine with an impregnable material is also recommended to resist future infiltration of PCE beneath the concrete and to limit indoor volatilization from the current PCE plume in I I I I I I I I I I I I I I I I I I I Phase II Site Assessment Report Country Club Cleaners 4800 White Lane.
