The state’s Department of Health can issue a guidance explaining the states’ experts’ analysis of the available data and tradeoffs of the decision, and let the municipalities sort it out.

I think the bigger complication though is going to be - depending on the state - how water districts are apportioned. I think even many counties (let alone municipalities) will share water infrastructure so it’s not really clear who has the jurisdiction to make that decision other than the state.

It also makes it easier for the consumer: don’t want fluoride, move to Utah. Rather than having to figure out what random water district is doing what.
