7C Page 9 City of Redwood City 2010 Public Health Goal Report regularly monitors at entry points and throughout the distribution system. This SFPUC report on Corrosion Control Strategy has been reviewed and approved by the California Department of Public Health. The City of Redwood City water system is in full compliance with all state and federal regulations including the Lead and Copper Rule. The system of pH adjustment employed by the SFPUC and the City of Redwood City's monitoring program are considered the best available technology for reducing lead and copper levels at customer taps. No Additional Action for Lead is Recommended As required by the CDPH, the SFPUC will continue to practice pH adjustment and the City of Redwood City will continue monitoring the pH levels in the distribution system to demonstrate that the system is maintaining optimal corrosion control conditions. In response to the CDPH regulations, the City of Redwood City will also continue home-tap sampling and will again conduct that monitoring during the year 2012. No additional action is recommended for the City of Redwood City regarding lead. What Consumers can do to Decrease Lead Exposure listed below are some steps consumers can take to reduce exposure to lead: . Have household water tested for lead. . Find out whether household pipes contain lead or lead solder. . Run household water for 15-30 seconds or until it becomes cold before using it for drinking or cooking; this flushes any standing lead from the pipes. . Avoid cooking with or drinking water from the hot water tap; lead dissolves more easily into hot water. . Avoid boiling water to remove lead; excessive boiling of water makes the lead more concentrated - the lead remains when the water evaporates. III. SUMMARY AND CONCLUSION The drinking water for the City of Redwood City meets all standards established by California Department of Public Health and USEPA to protect public health. No additional treatment is recommended at this time to lower the levels of lead. There are no clear benefits to be derived from expensive efforts to further reduce the levels of this contaminant for it is well below the level of concern and elimination may be impossible. Therefore, no further action is proposed for lead. IV. ATTACHMENTS: 1. Excerpt from California Health & Safety Code: Section 116470 (b), (c), (d), (e), and (f) 2.
