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.
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)
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
GCWW has always met or exceeded all of the state and federal health standards for drinking water and uses state-of-the-art water treatment processes that include multiple barriers to protect public health.
GCWW’s water plants employ various treatment processes, such as sand filtration, Granular Activated Carbon (GAC), Powdered Activated Carbon (PAC), and ultraviolet (UV) light to remove and treat for natural and man-made contaminants from our drinking water. It is one of the first in the nation to use a combination of all four treatment methods. GCWW also treats the drinking water specifically to minimize the amount of lead that may leach into the drinking water -- this treatment process is called corrosion control. This process ensures there is no lead in the water as it leaves GCWW treatment plants and minimizes the chance that lead can be picked up from home plumbing. More than 600 tests a day ensure that treatment is effective.
Although GCWW’s corrosion control treatment is extremely effective in minimizing lead, some sources of lead still exist which can potentially be picked up as the water flows from the utility-owned (public) lines into and throughout the home. GCWW takes the potential presence of lead very seriously and is working to further minimize the potential risks in the water distribution system.
