• Given that the ground elevation of the Site is approximately 98 to 100 feet above mean <br /> sea level, the depth to water below the Site is estimated to be to 74 to 90 feet, <br /> depending on the season. <br /> Potential Ground Water Contamination Issues <br /> The Soil Suitability Study is not intended to be an investigation into ground-water <br /> contamination sources, and no such investigation was conducted. Many sources can <br /> contribute to ground water contamination, including leaking underground storage tanks, <br /> agricultural activities, dairies, septic systems, and storm water infiltration. Agricultural <br /> activities and the use of septic systems in the area are known ground water <br /> contamination sources with the potential to impact the Site. <br /> Live Oak reviewed the EHD's Water Well Data Table dated March 10, 2009 for nearby <br /> addresses that have been tested for nitrate and dibromochloropropane (DBCP), <br /> common ground-water contaminants in San Joaquin County. Three wells were <br /> identified within approximately one mile of the Site. All three of the wells had been <br /> tested for nitrate; it was detected in all three, at concentrations of 18.0 to 38.0 mg/L- <br /> NO3. Only one of the wells had been tested for DBCP; no DBCP was detected. The <br /> Maximum Contaminant Level (MCL) set by the US EPA for nitrate as NO3 is 45 mg/L <br /> (10 mg/L-N); the MCL for DBCP is 0.2 [g/L. <br /> On-Site Wells <br /> • No wells are currently located on the Site. Ms. Armosino has indicated that a well will <br /> be drilled to serve the new house. No well permits were identified for the Site from <br /> among the files of the San Joaquin County Environmental Health Department. <br /> Water Sample <br /> No water sample was collected as part of this investigation. <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 <br /> Riverbank formation (Plate 7). <br /> The surface and near surface soils located at the Site are reported by the USDA Web <br /> Soil Survey to be composed of Veritas fine sandy loam (Plate 8) (USDA, 2019).
