The groundwater boring was drilled to a <br /> depth of 8.5 f�et.The percolation test holes were used later for percolation test holes; the locations <br /> of the borings are indicated in Plate 1. <br /> 5.2 Soil Boring Dimensions <br /> The percolation borings were approximately three and a half feet deep, as noted above, and were <br /> four inches in diameter. <br /> 5.3 Soil Lithology Observed <br /> Generally,the soil encountered in the boring is similar to the soils reported by the San Joaquin <br /> County Soil Survey for the area (USDA, 1992). Table 3 presents the soil logs for the three and a <br /> half foot soil borings. <br /> Table 3. <br /> Soil Boring Log for Designated Remainder. <br /> Depth Interval (ft) Soil Type Unified Soil Classification <br /> 0-I Light brown,very moist,cla} CL <br /> 1-3.5 Light brown,moist,clay with some silt and sand CL <br /> 6 '404 <br />
