As Recommended <br /> PUBLIC HEARING: REPORT ON WATER ? As Amended <br /> QUALITY RELATIVE TO PUBLIC HEALTH ? Ordinance on 15~ Reading <br /> ? Ordinance on 2"d Reading <br /> GOALS ? Implementing Resolution <br /> ? Set Public Hearing For <br /> CONTINUED TO <br /> ~~G - FILE NUMBER <br /> CITY MANAGER <br /> RECOMMENDED ACTION <br /> Accept the report on Water Quality Relative to Public Health Goals. <br /> DISCUSSION <br /> The California Environmental Protection Agency Office of Environmental Health Hazard <br /> Assessment establishes Public Health Goals (PHGs) for drinking water contaminants. The PHGs <br /> are guidelines and are not requirements for any public water system. PHGs are frequently much <br /> lower than the Maximum Contaminant Levels (MCLs) established by the United States <br /> Environmental Protection Agency (USEPA). Under provisions of the California Health and Safety <br /> Code, the City is required to prepare a special report identifying water quality measurements that <br /> have exceeded PHGs (Exhibit 1). <br /> For the years 2007, 2008, and 2009, the report shows that Santa Ana's drinking water continues to <br /> meet all State of California, Department of Health Services, and USEPA drinking water standards <br /> set to protect public health. However, the City's drinking water content of naturally occurring <br /> uranium, arsenic, and copper levels exceeded the recommended PHG levels. The report states <br /> that for naturally occurring uranium and arsenic, additional treatment would be very expensive, <br /> marginally effective, and would not result in significant reduction of the contaminants. Therefore, <br /> no action is proposed. <br /> The report also states that optimized corrosion control is the best available technology to reduce <br /> <br /> the copper levels. The California Department of Public Health has determined that the City has <br /> optimized corrosion control with our treatment and monitoring procedures. The implementation of <br /> new treatment technologies therefore is not recommended. <br /> State law specifies that a public hearing for the purpose of accepting and responding to public <br /> <br /> comments on the report be held. Tonight's public hearing will meet this legal requirement. <br /> 75C-1 <br /> <br />
