REQUEST FOR <br />COUNCIL ACTION <br />CITY COUNCIL MEETING DATE: <br />JIILY 2, 2007 <br />TITLE: <br />PIISLIC HEARING - REPORT ON DiATER <br />QIIALITY RELATIVE TO PIISLIC HEALTH <br />GOALS <br />/ CITY MANAGER <br />RECOMMENDED ACTION <br />CLERK OF COUNCIL USE ONLY: <br />APPROVED <br />^ As Recommended <br />^ As Amended <br />^ Ordinance on 1s` Reading <br />^ Ordinance on 2ntl Reading <br />^ Implementing Resolution <br />^ Set Public Hearing For <br />CONTINUED TO <br />FILE NUMBER <br />Accept the report on Water Quality Relative to Public Health Goals. <br />The California Environmental Protection Agency Office of Environmental <br />Health Hazard Assessment establishes Public Health Goals (PHGs) for <br />drinking water contaminants. The PHGs are guidelines and are not <br />requirements for any public water system. PHGs are frequently much lower <br />than the Maximum Contaminant Levels (MCLs) established by the United <br />States Environmental Protection Agency (USEPA). Under provisions of the <br />California Health and Safety Code, the City is required to prepare a <br />special report identifying water quality measurements that have exceeded <br />PHGs (Exhibit 1). <br />For the years 2004, 2005, and 2006, the report shows that Santa Ana's <br />drinking water continues to meet all State of California, Department of <br />Health Services, and USEPA drinking water standards set to protect public <br />health. However, the City's drinking water content of naturally <br />occurring uranium, arsenic, and copper levels exceeded the recommended <br />PHG levels. The report states that for naturally occurring uranium and <br />arsenic, additional treatment would be very expensive, marginally <br />effective, and will not result in significant reduction of the <br />contaminants. Therefore, no action is proposed. <br />The report also states that optimized corrosion control is the best <br />available technology to reduce the copper levels. The California <br />Department of Health Services has determined that the City has optimized <br />corrosion control with our treatment and monitoring procedures. The <br />implementation of new treatment technologies is therefore not <br />recommended. <br />75D-1 <br />
