Water & Your Health


Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that the water  poses a health risk. You can learn more about contaminants and potential health effects by calling the U.S. Environmental Protection Agency’s (USEPA) Safe Drinking Water Hotline at 800-426-4791 or visiting the website at epa.gov/safewater

In order to ensure that tap water is safe to drink, USEPA and the State Water Resources Control Board (State Board) prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. The U.S. Food and Drug Administration regulations and California law also establish limits for contaminants in bottled water that provide  the same protection for public health. Additional information on bottled water is available on the California Department of Public Health website: http://bit.ly/CDPH_FAQs.


People with Weakened Immune Systems

Although Santa Ana meets all drinking water standards, some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can  be particularly at risk from infections. These people should seek advice about drinking water from their health care providers.


USEPA/Centers for Disease Control (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline at 800-426-4791.
