The s -tfonng was used later for a percolation test hole; the location of the <br /> boring is in ' ate 1. <br /> 5.2 Soil Boring Dimensions <br /> The soil boring was approximately three and a half (3.5) feet, as noted above, and was four (4) <br /> 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). The table below presents the soil log for the soil <br /> borings. Conditions were comparable in the shallower holes. <br /> Table 2. <br /> Soil Boring Log. <br /> Depth Interval (ft) Soil Type Unified Soil Classification <br /> 0-3.5 Medium brown, clayey silt SM <br /> 5.4 Discussion of Soil Lithology <br /> A visual inspection of the soils from on-site drilling indicates some potential for percolation <br /> because of the variety of the soils which exist on site (Plate 6). A percolation test is the best <br /> method to determine the suitability of the soils for a septic disposal area. Please see the next <br /> section for percolation test results. Generally speaking, coarser-grained soils have much <br /> greater potential for percolation than fine-grained or cemented soils. <br /> ,.*44 <br /> 902 Industrial Way•Lodi,CA 95240•209.367.3701 •Fax 209.369.4228 02008 Neil O.Anderson&Associates,Inc <br />
