reasonably be required to remove this contaminant should it occur in drinking water. <br /> The Maximum Contaminant Level Goal (MCLG) for DBCP is zero. <br /> Soil Profile and Geologic Information <br /> The Site is depicted on the Preliminary geologic map showing Cenozoic deposits of the <br /> Bellota quadrangle, California (Marchand and Bartow, 1979). The Site is depicted <br /> within a map unit of the Turlock Lake formation, described as "arkosic alluvium, <br /> probably glacial outwash in part; includes some locally-derived alluvium in areas near <br /> the Calaveras River; chiefly sand with some silt and minor gravel" (Plate 11). <br /> The surface and near surface soils located at the Site are reported by the USDA Web <br /> Soil Survey to be composed of Montpellier-Cometa complex and Rocklin sandy loam <br /> (Plate 12) (USDA, 2019). The table below presents some selected properties of these <br /> soils: <br /> Table 1.
