The samples were then transported on ice and remanded <br /> E <br /> under chain of custody to FGL Environmental in Stockton, California. <br /> 1.4G6�Chain of Custody <br /> The Chain of Custody document has been included in the appendix of this report. <br /> 1.�Soil Profile and Geologic Information <br /> The Site is depicted on the California Geologic Survey Map of the San Francisco-San Jose <br /> Quadrangle as within the Quaternary Modesto Formation (Plate 5). The Quaternary Modesto <br /> Formation (undifferentiated) is unit of undifferentiated alluvial deposits, mainly arkosic, forming <br /> the toe of the Mokeiumne alluvial fan, generally covered by 0.3 to 1.0 m of Holocene intertidal <br /> 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 Tokay fine sandy loam, 0-2% slopes (Plate 6) (USDA, 1992). <br /> The table below presents some selected properties of these soils: <br /> Table 1 <br /> San Joaquin County Soil Survey <br /> Elected Soil Properties of On-Site Soils <br /> Soil.NameSoil Perme- Septic tank <br /> and Ma Depth Unified Soil Salinity <br /> p in classification mmhos/cm .Reaction ability, absorption <br /> Symbol ( } <br /> pH : (In/hr) fields. ,. <br /> 0-19 Fine sandy loam; SM <2 6.1-7.8 2,0-6.0 <br /> Tokay fine 19-45 Fine sandy loam, sandy <2 6.1-7.8 2,0-6.0 <br /> sandy loam, loam; SM <br /> 0-2 % slope Slight <br /> 256 45-60 Fine sandy loam, sandy <2 6.1-8.4 2.0-6.0 <br /> loam coarse sandy loam; <br /> SM <br /> Note: The table descriptions do not necessarily reflect site-specific soil properties. <br /> *See description of the map unit for composition and behavior characteristics of the map unit. <br /> f� <br /> 902 Industrial Way- Lodi,CA 95240-209.367.3701 -Fax 209.369.4228 ©2008 Neil a Anderson&Associates,Inc <br />
