Milwaukee Water Works Temporarily Reduces Fluoride Levels Due to Supply Shortage

Milwaukee, WI, July 29, 2026 —

Milwaukee, WI – Milwaukee Water Works has announced a temporary reduction in the amount of fluoride added to the city’s public drinking water supply. The change is attributed to a current shortage in the supply of fluoride chemicals, according to officials.

The specific timeline for this reduction and the exact quantity by which fluoride levels are being lowered were not immediately provided. Milwaukee Water Works stated that the adjustment is a precautionary measure to manage the existing supply constraints.

Fluoridation of public water supplies is a common public health practice implemented to help prevent tooth decay. The American Dental Association and the Centers for Disease Control and Prevention (CDC) recommend community water fluoridation as a safe and effective method for improving oral health.

The reduction in fluoride levels will remain in effect until the supply chain issues are resolved and normal delivery of fluoride chemicals can resume. Further updates on the situation are expected from Milwaukee Water Works as more information becomes available regarding the duration and specific impact of the reduced fluoride concentration.

Details regarding the cause of the supply shortage or the specific suppliers affected were not disclosed. The utility is monitoring the situation closely and is working to restore the standard fluoride dosage as soon as possible.
