should it occur in drinking water. The Maximum Contaminant Level Goal (MCLG) for DBCP is zero. The laboratory analytical results are attached as Appendix 5 of this report. Soil Profile and Geologic Information The Site is mapped on the Geologic Map of California, San Jose sheet (Rogers, 1966). It is depicted within a map unit of recent Great Valley fan deposits (Plate 7). The surface and near surface soils located at the Site are reported by the USDA Web Soil Survey to be composed of Capay clay, EI Solyo clay loam, and Stomar clay loam (Plate 8) (USDA, 2009). The table below presents some selected properties of these soils: Table 1.
