U.S. Water Systems with High F Levels

Database of drinking water systems with high levels of naturally occurring fluoride; searchable by state.

South Dakota

Unless otherwise noted, the following information comes from the Fluoridation Census 1992 published by the Centers for Disease Control and Prevention, Division of Oral Health, in 1993.

• It is not known if the water systems listed below are all still active
• The state Water System ID is the same as EPA’s preceded with the state’s initial. For example, South Dakota would be SD0000000
