Fluoridation of Drinking Water


You may have heard that the federal Department of Health and Human Services has recommended a level of 0.7 milligrams per liter as optimal for fluoride in drinking water throughout the United States.

The State Board of Health, which oversees the state's fluoridation of drinking water rule, has revised the rule to reflect this new standard. The new rule was adopted by the Board on March 9, 2016 and went into effect May 9, 2016.
