Soil Profile and Geologic Information <br /> The Site is depicted on the Preliminary geologic map of Cenozoic deposits of the <br /> Bellota Quadrangle, California (Marchand and Bartow, 1979). The Site is depicted <br /> within a map unit of the Modesto Formation upper member, described as "arkosic <br /> alluvium forming Mokelumne River terraces and alluvial fan; chiefly sand with minor <br /> gravel and silt; probably glacial outwash" (Plate 7). <br /> The surface and near surface soils located at the Site are reported by the USDA Web <br /> Soil Survey to be composed of Acampo sandy loam, with a small area of Kingdon fine <br /> sandy loam near the Mokelumne River (Plate 8) (USDA, 2016). The table below <br /> presents some selected properties of these soils: <br /> Table 1.

According to the <br /> form, the boring for the percolation test was four inches in diameter and 3.5 feet deep. <br /> The location of the boring is indicated on the percolation test form (Appendix 2) and on <br /> Plate 9. <br /> LOGE 1729 Page 5 <br />
