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 Geologic Map of the San Francisco-San Jose Quadrangle, <br /> California (Wagner et al., 1991). The Site is depicted within a map unit of the Modesto <br /> formation (Plate 9). <br /> The surface and near surface soils located at the Site are reported by the USDA Web <br /> Soil Survey to be composed of Delhi loamy sand and Veritas fine sandy loam (Plate 10) <br /> (USDA, 2022). The table below presents some selected properties of these soil types: <br /> Table 1.

Shallow borings were excavated on seven parcels; both <br /> shallow and deep borings were excavated on the remaining three parcels. The borings <br /> was four inches in diameter, 1.81 to 7.99 feet deep, and were excavated by hand auger <br /> (Table 2). The locations of the borings are indicated on Plate 11. <br /> The soil in the borings was similar to that described by the Soil Survey. Sand/silt <br /> combinations were encountered to the full depth of each hole. The soil logs are <br /> presented on Plates 12 through 17. <br /> LOGE 2217 Page 5 <br />
