A well inspection will then be conducted <br /> and, where necessary, sampling port will be installed at the well heads. Those operations are <br /> expected to be completed within two weeks of SJC receiving well owners authorization to <br /> proceed and the sampling will be performed during the following week. Following sample <br /> recovery, the results of the analyses of the potable water will be available within two weeks <br /> and will be included in quarterly groundwater-quality monitoring reports that will be <br /> submitted to the SJCEHD and the RWQCB. <br /> As requested by the SJCEHD (San Joaquin County Environmental Health Department 2003), <br /> following the initial round of potable water quality monitoring, sample recovery from each off` <br /> the domestic wells listed above will be repeated at quarterly intervals. <br /> Note: <br /> Due to the fire that severely damaged the Casa Mendoza restaurant on the 7500 <br /> West Eleventh Street Site, the potable water well that serves that property, which <br /> is located within the restaurant building, cannot be sampled until the restaurant <br /> reconstruction has been completed, Accordingly, if the reconstruction work has <br /> ,omwo not been completed by the time the first round of potable water sampling is <br /> SJC <br />
