Water & Your Health

Drink To Your Health

Experts recommend drinking 8 cups of water per day (some of this water may come from foods). Drinking GCWW tap water is a good way to do this.

Cincinnati drinking water contains small amounts of naturally occurring minerals. We add fluoride to protect teeth (as required by law).

The most frequent question we get about nutrients is how much sodium is in Cincinnati water.

Sodium Values

These amounts are for the water as it leaves treatment plants; percent of Daily Values are based on a 2,000-calorie diet:

  • Miller Water (from the Ohio River): 32 mg/Liter (1% of Daily Value)

  • Bolton Water (from the Great Miami Aquifer): 28 mg/Liter (1% of Daily Value)

Cryptosporidium

GCWW has tested for Cryptosporidium (Crypto) in treated water and has never detected it. Crypto is a microscopic organism that, when ingested, can result in fever, gastrointestinal symptoms, and diarrhea. The organism is found in surface waters and comes from animal and human wastes in the watershed. Crypto is eliminated by an effective treatment combination including sedimentation, filtration and disinfection.

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

USEPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the EPA Safe Drinking Water Hotline: 1-800-426-4791.

About Lead & Your Drinking Water

There is no detectable lead in our drinking water as it leaves the treatment plants. It is possible that lead levels in your home may be higher than in other homes in the community because of your home's pipes and plumbing fixtures. Infants and young children are typically more vulnerable to lead in drinking water than other people.

If you have questions about lead, please call GCWW at 513-591-7700 and select option 5.

Flushing your tap for up to three minutes before using the water and using only cold water for cooking are helpful.
