Water Sample <br /> Because the well is out of service, no water sample was collected from the Site. <br /> Soil Profile and Geologic Information <br /> The Site is depicted on the Prelim+n4ry Geologic map of Cenozoic Deposits of the <br /> Bellota Quadrangle, California (Marchand and Atwater, 1979). The Site is depicted <br /> within three map units-. Holocene alluvium, the Riverbank Formation lower unit, and the <br /> Turlock Lake Formation -(Plate 7). Holocene alluvium consists of channel and levee <br /> deposits. The Riverbank Formation lower unit is described as "arkosic alluvium, <br /> probably glacial outwash, and locally-derived sandy alluvium; chiefly _sand." The <br /> Turlock Lake Formation is described as "arkosic alluvium, probably glacial outwash in <br /> part; chiefly sand with some silt and minor gravel." <br /> The surface and near surface soils located at the Site are reported by the USDA Web <br /> Soil Survey to be composed of Kingdon fine sandy loam, Ramoth sandy loam, and Vina <br /> fine sandy loam, with gravel pits located on the southern portion of the Site (Plate 8) <br /> (USDA, 2009). The table below presents some selected properties of these soils: <br /> Table 1.
