No permits were found during a recent file review at the EHD. <br /> No well water sample was analyzed. <br /> 1.5 Soil Profile and Geologic Information <br /> The Site is depicted on the USGS Preliminary Geologic Map San Francisco-San Jose Quadrangle <br /> as within the Quaternary Modesto Formation composed of undifferentiated alluvial deposits, <br /> mainly arkosic, forming toe of the Mokelumne alluvial fan, generally covered by 0.3 to 1.0 <br /> meters of Holocene intertidal deposits. <br /> The surface and near surface soils located at the Site are reported by the San Joaquin County <br /> Soil Survey to be composed of Jack Tone clay and Stockton clay, both 0-2 slopes (Plate 6) <br /> (USDA, 1992). The table below presents some selected properties of these soils: <br /> Table 3. <br /> San Joaquin County Soil Survey <br /> Selected Soil Pro erties of On-Site Soils. <br /> Soil Name and Depth Unified Soil Salinity Soil Perme- Septic tank <br /> Reaction ability absorption <br /> Map Symbol (in) Classification (mmhos/cm) <br /> pH (in/hr) fields <br /> Jacktone 0-22 Clay; CL, CH <2 6.6-8.4 0.06-0.2 Severe: <br /> 180 22-34 Clay loam, clay <2 7.9-9.0 0.06-0.2 cemented <br /> silty clay; CL, CH pan, peres <br /> 34-37 Indurated slowly <br /> 37-46 Loam, clay <2 7.9-9.0 0.2-0.6 <br /> 46-60 IoamCL-ML, CL --- --- --- <br /> Cemented <br /> Jack Tone, 0-22 Clay; CL, CH <2 6.6-8.4 0.06-0.2 Severe: <br /> Urban Land 22-34 Clay loam, clay <2 7.9-9.0 0.06-0.2 cemented <br /> Complex, 0-2% silty clay; CL, CH pan, peres <br /> slopes, 181 34-37 Indurated --- --- --- slowly <br /> 37-46 Loam, clay <2 7.9-9.0 0.2-0.6 <br /> 46-60 IoamCL-ML, CL --- --- --- <br /> Cemented <br /> Stockton clay, 0-29: Clay; CL, CH <2 7.4-8.4 0.14-0.16 Severe: peres <br /> 0-2% slopes, 29- Clay, silty clay; <2 7.4-8.4 0.14-0.16 slowly <br /> 250. 37: CL, CH <2 7.4-8.4 0.14-0.17 <br /> 37-42: Clay loam, silty --- --- <br /> 42-60: clay loam; CL <br /> Cemented <br /> v <br /> 902 Industrial Way•Lodi,CA 95240.209.367.3701 •Fax 209.369.4228 02008 Neil 0.Anderson&Associates,Inc <br />
