On-Site Wells <br /> One active public well is located to the southeast of the restaurant on the Site. Based <br /> on Mr. Rizkallah's conversation with previous owner Carl Navarra, an out-of-service well <br /> is located in or adjacent to the shop on the Site (personal communication, September <br /> 23, 2022). Three well permits were identified from among the files of the San Joaquin <br /> County Environmental Health Department: <br /> • May 1978 permit for pump repair at industrial well. <br /> • June 1999 permit for pump replacement at public well. The well is depicted <br /> inside the fuel station building. <br /> • December 2006 permit for pump replacement at domestic well. <br /> These permits have been included in Appendix 4 of this report. <br /> Water Sample <br /> Live Oak collected a water sample from the public well southeast of the restaurant on <br /> the Site on August 24, 2022. The sample was analyzed for nitrate and <br /> dibromochloropropane (DBCP) per San Joaquin County Environmental Health <br /> Department policy. <br /> As required by the laboratory, the sample was collected in a plastic container and three <br /> glass vials for nitrate and DBCP analysis, respectively. Trip blanks were also utilized. <br /> The sample was placed on ice and transported under chain of custody to FGL <br /> Environmental, Stockton. <br /> Neither nitrate nor DBCP was detected in the sample. The laboratory analytical results <br /> are attached in Appendix 5 of this report. <br /> Additionally, Mr. Rizkallah provided Live Oak with sampling results from June of 2022 in <br /> which the well water was analyzed for pH, calcium, hardness, magnesium, manganese, <br /> sodium, iron, fluoride, nitrate, and nitrite. The laboratory reported a detection of <br /> manganese at 289 µg/L, above the MCL of 50 µg/L. Nitrate was reported at 0.48 mg/L- <br /> N. These laboratory analytical results are attached in Appendix 5 of this report. <br /> Soil Profile and Geologic Information <br /> The Site is depicted on the Preliminary geologic map of the Tracy quadrangle, San <br /> Joaquin County, California (Diblee, 1981) as within a map unit of Holocene alluvium <br /> (Plate 9). <br /> LOGE 2240 Page 6 <br />
