REQUEST FOR <br />COUNCIL ACTION <br />CITY COUNCIL MEETING DATE: <br />MAY 21, 2019 <br />TITLE: <br />RECEIVE AND FILE <br />REPORT ON WATER QUALITY <br />{STRATEGIC PLAN NO. 5} <br />CLERK OF COUNCIL USE ONLY: <br />APPROVED <br />❑ As Recommended <br />❑ As Amended <br />❑ Ordinance on 1$' Reading <br />El Ordinance on 2ntl Reading <br />❑ Implementing Resolution <br />❑ Set Public Hearing For <br />CONTINUED TO <br />FILE NUMBER <br />CITY MANAGER <br />RECOMMENDED ACTION <br />Receive and File Water Quality Report. <br />DISCUSSION <br />The City's Water Resources Division provides potable drinking water for all of the City's residents <br />and businesses, delivering an average of 30 million gallons each day. In order to accomplish this, <br />the City owns and operates a water system that consists of 480 miles of pipe, 22 groundwater <br />wells, 4 pressure control stations, 7 import water connections, 7 water booster stations and 8 <br />reservoirs, and 45,000 metered service connections. <br />The City publishes an annual report on the quality of the water served to all residents. The water <br />quality served by the City has always exceeded all established enforceable water quality standards <br />set by both Federal and State governments. Just recently, and as a result of monitoring water <br />supplies under the Unregulated Contaminant Monitoring Rule phase three (UCMR3) monitoring <br />regulations, the State and Federal regulatory communities have become concerned with two <br />potential chemicals, namely perFluorooctanesulfonic acid (PFOS) and perflurooctonaoic acid <br />(PFOA) in the groundwater. Both chemicals are part of a family of chemicals known as per- and <br />polyfluoroalkyl substances (PFAS). Scientific studies of these chemicals indicate that exposure to <br />PFAS can lead to significant health effects, especially in women who are pregnant or likely to <br />become pregnant and in children. <br />UCMR3 testing showed that none of these chemicals have been found in the City of Santa Ana <br />water wells. However, the State Water Resources Control Board (SWRCB) requested that <br />additional monitoring (sampling and testing) be conducted on one of the City's water wells as part <br />of a state-wide monitoring mandate. <br />The reason for selecting one particular City well for additional monitoring was based on the <br />proximity of the well to others not owned by the City that have the potential to test positive for the <br />19E-1 <br />
