The soil borings were used later for percolation test <br /> holes; the locations of the borings are indicated in Plate 1. <br /> 5.2 Soil Boring Dimensions <br /> The soil borings were approximately 3.5 feet, as noted above, and were four (4) 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). 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 /> 0-8.5 Brown, silty clay CL <br /> 5.4 Discussion of Soil Lithology <br /> A visual inspection of the soils from on-site drilling indicates little potential for percolation <br /> because of the fine-grained nature of the soils. A percolation test is the best method to <br /> determine the suitability of the soils for a septic disposal area. Please see the next section for <br /> percolation test results. Generally speaking, coarser-grained soils have much greater potential <br /> for percolation than fine-grained or cemented soils. <br /> 902 Industrial Way• Lodi,CA 95240.209.367.3701 •Fax 209.369.4228 ('2008 Neil O.:b0crson&,Issociales.!nc <br />
