View each tabbed section as PDF below.
- Fluoridating Systems (green list): (PDF) The systems on this list artificially adjust fluoride in water for dental benefits. The fluoride concentration is between 0.8 mg/L and 1.3 mg/L.
- Intertied Systems (blue list): (PDF) The systems on this list are connected to the Fluoridating Systems and have no other sources that would dilute the concentration of fluoride. The water system doesn’t fluoridate but consumers still receive water with fluoride levels between 0.8 mg/L and 1.3 mg/L.
- Natural: (PDF) The test results of these systems show natural fluoride levels at or above 0.6 mg/L. Systems that have optimal natural fluoride levels between 0.8 and 1.3 mg/L have a grey background.
