Madison Utilities votes to eliminate fluoride from water treatment by June 16

Madison Utilities is making a significant shift in its water treatment practices, voting to remove fluoride from its water supply effective June 16, 2025. This decision comes after a series of developments regarding fluoride levels and water treatment strategies in the city.

In February 2015, the U.S. government lowered the recommended optimal level of fluoride to 0.7 milligrams per liter. Following this, Madison Utilities adopted a plan in 2018 to scale back operations at its key water treatment plant. By February 2020, the strategy evolved again, with plans to recondition the plant, although it was noted that substantial renovations would still be necessary.

In 2024, engineers discovered significant structural damage and issues with chemical feed equipment at the facility. This prompted a redesign of the project, including relocating fluoride storage and dosing systems to a new facility, with preliminary estimates for this work around $450,000. The board was made aware of the hazardous nature of fluoride, which raised concerns for both employees and infrastructure.

The decision to eliminate fluoride aligns with broader legislative trends, as seen in recent actions by other states. On March 17, 2025, the Madison Utilities Board voted to proceed without fluoride in its water treatment contract. This decision reflects a growing movement against fluoridation, highlighted by recent legislative changes in Louisiana and Utah.

The public hearing held on May 13, 2025, drew significant attention, with 71 attendees and 78 registered speakers, indicating strong community interest in the fluoridation issue. As the FDA also began actions to remove certain fluoride products from the market, Madison's decision marks a pivotal moment in the city's approach to water safety and public health.
