Should I be concerned about cryptosporidium in my drinking water?
Current EPA drinking water standards are designed to assure 99% removal or killing of Cryptosporidium. People who have severely weakened immune systems (immunocompromised) are more high-risk to infection than the general population and may want to take extra precautions. These include pregnant women, infants, the elderly, people with HIV / AIDS, organ transplants, and people on cancer therapy. Cryptosporidiosis is not treatable with antibiotics, so prevention of infection is critical. People with weakened immune systems will have cryptosporidiosis for a longer period of time, and it could become life-threatening. Young children, pregnant women, or the elderly infected with cryptosporidiosis can quickly become severely dehydrated.

EPA and the Centers for Disease Control and Prevention (CDC) have developed guidance for severely immunocompromised people. Such individuals should consult with their health care provider about what measures would be most appropriate and effective for reducing their overall risk of Cryptosporidium and other types of infection. Visit the U.S. Environmental Protection Agency Ground Water and Drinking Water for information on health effects and concerns.
