• syndrome, which results in reduced oxygen supply to vital tissues. Pregnant women and certain others can also develop methemoglobinemia. Symptoms include a bluish color of the skin, as well as headache, dizziness, weakness, and difficulty breathing. Ingestion of high levels of nitrates over time can also lead to gastric problems. DBCP is a nematocide and soil fumigant for vegetables and grapes. It is known to cause male reproductive effects and is classified as a probable human carcinogen. Most domestic use of DBCP was discontinued in 1977 through 1979. The US EPA set the MCL at 0.2 parts per billion (ppb, equivalent to µg/L) because it believes that given present technology and resources, this is the lowest level to which water systems can reasonably be required to remove this contaminant 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 (Rodgers, 1966). It is depicted within a map unit of Great Valley fan deposits (Plate 7). The surface and near surface soils located at the Site are reported by the Web Soil Survey (USDA, 2015) to be composed of Veritas fine sandy loam (Plate 8). The table • below presents some selected properties of this soil: Table 1.

See description of the map unit for composition and behavior characteristics of the map unit. Soil Borings On July 18, 2016, Live Oak excavated a shallow soil boring on each proposed parcel the Site for the purpose of conducting percolation tests. The borings were four inches in diameter, 3.30 and 3.35 feet deep, and were excavated by hand auger (Table 2). The locations of the borings are indicated on Plate 9. The soil in the borings was similar to that described by the Soil Survey. Silty sand was • encountered to the full depth of both holes. The soil log is presented on Plate 10. LOGE 1613 Page 5
