1 ! • i • B5-S2: Soil sample collected between roughly 13 to 15 feet bgs (VOCs, TPH-DRO, TPH-GRO, 1 and PCBs); • B6-SI: Soil sample collected between roughly 13 to 15 feet bgs (VOCs and RCRA 8 Metals); and • B6-S2: Soil sample collected between roughly 13 to 15 feet bgs(VOCs and RCRA 8 Metals). 1 A physical description of the soil types encountered was recorded on boring logs in general accordance with the Unified Soils Classification System (USCS). Subsurface deposits were observed to consist 1 predominantly of fine-grained sand and silt mixed with varying clay content to depths of 20 feet bgs. Boring logs depicting the subsurface lithology beneath the subject property at the boring locations are included as Appendix A. 1 Each of the borings was backfilled using a mix of 95 percent Portland Cement and 5 percent bentonite and the surface restored. Samples were collected in new, specially cleaned containers provided by the 1 analytical laboratory and specific to the analysis to be performed. If appropriate for the analysis, each sample container was filled completely so that no headspace was present in the containers. Sample containers were labeled with the site name, sample designation, and date and time of collection; and then placed in a rigid cooler and chilled to approximately four degrees Celsius for transport to the analytical 1 laboratory. 4.0 LABORATORY TESTING 1 A chain-of-custody was completed for the samples, which were delivered to Curtis & Tompkins, Ltd. of Berkley, California for analysis. Collected soil samples were analyzed for the presence of VOCs using 1 EPA Method 8260B, TPH-GRO and TPH-DRO using EPA Method 8015B, PCBs using EPA Method 8082,RCRA 8 Metals using EPA Method 6010. A copy of the laboratory report and chain-of-custody are attached as Appendix A. Relevant data from the laboratory testing of samples collected during this investigation are summarized in Table 1. i5.0 SUMMARY OF RELEVANT FINDINGS 1 The following findings are based upon field observations and measurements, review of analytical data, comparison of analytical results with applicable regulatory levels, and comparative evaluation of contaminant concentrations with known environmental conditions of the surrounding area. 1 5.1 Field Investigation Findings The following findings are based upon field observations and measurements: 1 • Soils encountered at the subject property consisted predominantly of a fine-grained sand and silt with varying clay content. ' • Groundwater was not encountered in any of the borings advanced at the subject property. • Soils with `petroleum like' odors and/or visual staining were encountered in Boring B3 from 1 approximately 7 to 12 feet bgs; in Boring B4 from roughly 5 to 9 feet bgs; and in Boring B5 at roughly 6 feet bgs in Boring B5. 1 1 Limited Subsurface Investigation (J&D Trust)J&D Auto Body 6 �+uch. 1011 Cherokee Lane, Lodi, California f.
