6 %00 ..W <br /> LOctober 5,2005 <br /> NOA Project Number: E05129A <br /> L <br /> The surface and near surface soils located at the Site are reported by the San Joaquin County Soil Survey <br /> to be composed of Stomar clay loam, 0-2 percent slopes (Plate 4) (USDA, 1992). Table 3 presents <br /> some selected properties of the soils: <br /> Table 3. <br /> ` San Joaquin County Soil Survey <br /> Selected Soil Properties of On-Site Soils. <br /> Soil Name Depth Unified Soil Classification Salinity Soil Perme- Septic tank <br /> and Map (in) mmhos/ Reaction ability absorption <br /> Symbol cm pH (in/hr) fields <br /> Stormar 0-17: Clay loam;CL <2 6.6-7.3 0.16-0.18 Severe:peres <br /> L day loam, 17-47: Clay loam,clay;CL,CH <2 6.6-8.4 0.16-0.18 slowly <br /> 0-2% <br /> slopes,252. 47-60: Clay loam,silty clay loam;CL <2 7.4- 8.4 0.16-0.18 <br /> Note:The table descriptions do not necessarily reflect site-specific soil properties. <br /> t <br /> 5.1 Soil Boring Locations <br /> One soil boring was advanced to a depth of approximately three and a half feet on the Site. The soil <br /> boring was later used for a percolation test hole. The location of the boring is indicated in Plate 1. <br /> ` 5.2 Soil Boring Dimensions <br /> to diameter.soil boring was approximately three and a half feet deep, as noted above, and was four inches in <br /> diameter. <br /> t- 5.3 Soil Lithology Observed <br /> LGenerally, 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 4 presents the soil logs for the three foot deep <br /> soil boring. <br /> V <br /> L <br /> 1 <br /> L g '044 <br /> L <br />
