State Fluoride Database

Read the latest fluoride news from your state; find out if your town is fluoridated, see if any communities have recently rejected fluoridation, learn if your state has a law that mandates fluoridation, and other fluoride-related information.



For a quick overview, Michael Dolan, in his November 2021 Fluoridation Review, listed the fluoridated and non-fluoridated cities, towns and counties in Wisconsin. They are listed at the bottom of the page.

October 12, 2020. Wisconsin state dental director uninformed on fluoride’s mechanism of action


  • FEBRUARY 1992 — Rice Lake: Residents vomiting. Centers for Disease Control state that 150 water consumers potentially at risk. A pump feed thought to have lasted for two days leads to fluoride levels as high as 20 ppm. The Wisconsin State Dental Director states, “To be harmful, exposure would have to have been about 225 ppm.” This statement is incorrect, as serious adverse symptoms have been reported as low as 50 ppm, and death has occurred at 150 ppm. (SOURCE: Carton 1994)
  • OCTOBER 1990 — Westby: Fluoride levels reach as high as 150 ppm after fluoridation malfunction. Four families suffer a week of diarrhea, upset stomach and burning throats. The water utility supervisor estimates the fluoride level to be ten times normal since it had burned his mouth. The elevated fluoride levels corrode the copper off the pipes in area homes, producing copper concentrations 70 times higher than the EPA recommended limit. (SOURCE: Carton 1994)

  • Report, Fluoridation of Public Drinking Water, by Public Health Madison & Dane County, June 4, 2014. The report included two arguments against fluoridation: “Opponents of water fluoridation of community water supplies cite two major issues to question the effectiveness of the program; a comparable reduction in dental caries in non-fluoridated communities and the improved availability of fluoride-containing products make the treatment of community drinking water unnecessary,” …


  • The State of Wisconsin does not mandate fluoridation.  Local governments control fluoridation policy in WI.  City councils can begin or discontinue fluoridation at their discretion, or by a referendum vote.  To learn more about WI’s fluoridation ordinances, click here.

Information from CDC’s Fluoridation Census published in 1993.


In 2008, Wisconsin ranked #17 out of 48 states for Hydrogen Fluoride releases (1,242,523 pounds). The following data comes from EPA’s Toxic Release Inventory (TRI). “Total releases” includes both water and air pollution. It’s important to note, however, that not all industries or sources that release fluoride into the environment are included in the TRI.
