6. <br /> May 5,2005 <br /> NOA Project Number: E05057A <br /> 5.1 Soil Boring Locations <br /> Four soil borings with a depth of about three and a half feet were advanced on the Site. The soil <br /> v boring was later used as a percolation test hole, see Plate 1 or a ring olocation. <br /> 5.2 Soil Boring Dimensions <br /> The soil borings were about three and a half feet deep, as noted above, and was four inches in <br /> 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).Tables 5 through 8 present the soil logs for the three <br /> foot deep soil borings. <br /> Table 5. <br /> Soil Boring Log for P-1. <br /> Depth Interval (ft) Soil Type Unified Soil Classification <br /> 0-2.0 Dark brown,moist clay with sand and silt CI, <br /> 2.0-3.5 Light brown,very moist,dayey silt with sand ML <br /> Table 6. <br /> Soil Boring Log for P-2. <br /> Depth Interval(ft) Soil Type Unified Soil Classification <br /> 0-1.0 Dark brown,moist clay with sand (-1- <br /> 1.0-3.5 Light brown,moist,very sandy clay with silt I C1, <br /> Table 7. <br /> Soil Boring Log for P-3. <br /> Depth Interval (ft) Soil Type Unified Soil Classification <br /> 0-1.0 Medium brown,moist,sandy clay CL <br /> 1.0-3.5 Medium to light brown,very moist,clayey sand SC <br /> 8 "O"A <br />
