The city’s water utility introduces a fluoride compound into its drinking water to raise the concentration of the element to 0.7 milligrams per liter. About 0.2 milligrams of fluoride are naturally present in the water before it passes through the Loveland Water Treatment Plant.

Cities commonly add fluoride to their drinking water because of its effects on dental health. Loveland began fluoridating its water in 1954. Since then, the consensus among public health experts has been that fluoride is not harmful at the levels achieved by fluoridation.

The efficacy of water fluoridation is supported by the Larimer County Department of Health and Environment, Colorado Department of Public Health and Environment, Centers for Disease Control and Prevention, American Dental Association, American Water Works Association, U.S. Public Health Service and other agencies.
