The surface and near surface soils located at the Site are reported by the USDA Web <br /> Soil Survey to be composed of Redding gravelly loam and San Joaquin sandy loam <br /> (Plate 8) (USDA, 2009). The table below presents some selected properties of these <br /> soils: <br /> Table 1.

The borings <br /> were four inches in diameter, 3.11, 3.18, 3.25, and 3.20 feet deep, and were excavated <br /> by hand auger. The boring locations are indicated on Plate 2. <br /> The soil in the borings was similar to that described by the Soil Survey; sand-clay <br /> mixtures were observed in most borings to the full depth. The logs for the sail borings <br /> are presented in Plates 9 through 12. <br /> Discussion of Soil Lithology <br /> Based on the soils observed in the borings, there appears to be moderate potential for <br /> percolation. Sandy soils generally have a much greater potential for percolation than <br /> fine-grained or cemented soils. However, a percolation test is the only accepted <br />{ <br /> LOGE1030 Page 5 <br />
