How to find out how much fluoride is in your water
If you receive your tap water from a local water utility, you can find out its fluoride content. Click on a county on the map, or select a county from the list below to view information on the community water systems in that county. The number of persons served and the fluoride content of each system are provided. Currently, the optimum recommended level of fluoride in drinking water in Ohio to prevent tooth decay is 1.0 part per million (ppm) or 1.0 mg/L. Recently, the U.S. Department of Health and Human Services proposed changing the optimum level of fluoride in drinking water to 0.7 ppm or 0.7 mg/L. More information is available about the proposed recommendation.
If you receive your tap water from a private well, a laboratory will need to analyze a sample of your water to determine the fluoride content. Click here to find out how to have your water tested for the fluoride content.
