This unit is described as gravel, <br /> sand, silt and clay (she Pla 5). <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 Capay clay, wet 0-2% slopes (Plate 6) (USDA, 1992). The table <br /> 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 Name Salinity Soil Perme- Septic tank <br /> and Map Depth Unified Soil mmhos/ Reaction ability absorption <br /> Symbol (�n) Classification cm pH (in/hr) fields <br /> 0-20: Clay; CH, CL <4 � 6.6 - 8.4 0.06 - 0.2 <br /> Capay Clay, Severe: <br /> wet, 0-2% 20-44: Clay, silty clay: CH, CL <4 , 6.6 - 8.4 0.06 - 0.2 percolates <br /> slopes, 121 slowly <br /> 44-60: Silty clay loam, clay <4 6.6 - 8.4 0.06 - 0.2 <br /> loam: CL <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 /> 5.1 Soil Boring locations <br /> j <br /> A total of two (2) soil borings and one (1) groundwater boring were advanced on the Site, two <br /> (2) soil borings to a depth of approximately three and a half feet (3.5) and an eight and a half <br /> (8.5) foot groundwater boring. The soil-borings)were used later for percolation test holes; the <br /> locations of the borings are indicated in Plate 1. <br /> 5.2 Soil Boring Dimensions <br /> The groundwater boring was approximately eight and a half (8.5) feet in depth. The soil <br /> borings were approximately three and a half (3.5) feet in depth, as noted above, and were four <br /> (4) inches in diameter. <br /> "'44 <br /> 902 Industrial Way- Lodi,CA 95240.209.367.3701 -Fax 209.369.4228 02008 Nei/O.Anderson&Associates. hic <br />
