Califia has <br /> started the next phase of their River Islands project and the current well locations will interfere <br /> with future infrastructure. <br /> The wells are used to measure depth to groundwater using "continuous" water level monitors; no <br /> water quality data is collected. The wells are included in the City of Lathrop's network of <br /> monitoring wells providing one average daily value to the RWQCB each quarter. <br /> The City of Lathrop has approved the removal of the wells, provided they are replaced at a later <br /> date. After the new Waste Discharge Requirements are issued, River Islands will work with the <br /> City to locate new wells in a location that works best with the future infrastructure and RWQCB <br /> monitoring requirements. <br /> Please let me know if you have any questions. <br /> Regards, <br /> Patrice - ynn <br /> Director of Public Works <br /> City of Lathrop <br /> Attachments: Order R5-2006-0094 Attachment E.1 <br />
