National Health Agencies Consider New, Optimal Fluoride Level in Drinking Water

Friday January 7, 2011

On Friday, January 7, the U.S. Department of Health and Human Services (HHS) and the Environmental Protection Agency (EPA) announced their intent to set a new, optimal fluoride level in drinking water. The groups are looking to set an optimal level of 0.07 parts per million (ppm). This would replace a current recommended range of 0.07 – 1.2 ppm.

The fluoride level in Louisville’s drinking water supply ranges between 0.9 and 1.0 ppm. The HHS and EPA said the review would ensure that fluoride guidelines continue to provide the best support for good dental health.

Louisville was one of the first cities in the nation to fluoridate its drinking water supply. Today, the State of Kentucky requires public water providers to fluoridate the water. Learn more about fluoride.
