The two (2) soil borings were used later for percolation test holes; the locations of the <br /> borings are indicated in Plate 1. <br /> 1.5.2 Soil Boring Dimensions <br /> The soil borings were 3.35 and 5.25, as noted above, and were four (4) inches in diameter.; <br /> 1.5.3 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 i <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 Medium brown, sandy silt SM <br /> 1.5.4 Discussion of Soil Lithology <br /> A visual inspection of the soils from on-site drilling indicates potential for percolation because of <br /> the coarser-grained nature of the soils. A percolation test is the best method to determine the <br /> suitability of the soils for a septic disposal area. <br /> 902 Industrial Way•Lodi,CA 95240•209.367.3701 •Fax 209.369.4228 02008 Neil O.Anderson&Associates,Inc <br />
