Cryptosporidium in Water

Cryptosporidium is a naturally-occurring, microscopic organism that may enter lakes and rivers from the fecal matter of humans or infected domestic and wild animals. When healthy adults are exposed to Cryptosporidium through the food or water they ingest, it can cause diarrhea, fever and stomach pains. For individuals with compromised immune systems, exposure to Cryptosporidium may pose a more serious health threat.

We are committed to providing protection against Cryptosporidium and other microorganisms by using a multi-barrier treatment approach. Although we are already meeting all EPA Cryptosporidium requirements with existing facilities and technologies, we will continue to pursue new technologies that may provide improved protection.

Health Alert

The presence of contaminants does not necessarily indicate that water poses a health risk. All drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. Read More

More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water hotline at 1-800-426-4791. You may also visit their Web site at

Some people are more vulnerable to contaminants in drinking water than the general population. Immuno-compromised individuals such as those undergoing chemotherapy, those who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, and some elderly people and infants can be particularly at risk. These people should seek advice about drinking water from their health care provider.
