Due to a <br />variety of issues, including the presence of per- and polyfluoroalkyl substances (PFAS) <br />found in routine well monitoring, several wells in the City have been taken offline. Given <br />the limited water supplies in the region, and recent recurring drought conditions, removing <br />wells from the City’s potable water distribution system will reduce its reliability. <br />Rehabilitating existing wells or constructing new wells will reduce the burden on other City <br />water production facilities and the reliance on imported water sources. <br />The Water Resources Division is currently finalizing the design of the Washington Well <br />Project, which will construct a new well that will address low-pressure deficiencies in the
