This bill would require the Environmental Protection Agency (EPA) to get a rapid, independent science review before proposing any new national limits for fluoride in drinking water. The EPA would ask the National Academies of Sciences, Engineering, and Medicine to review the evidence within 90 to 180 days, share all data used to justify the proposal, and then consider the findings. The full review report would be published alongside the EPA’s proposed rule so the public can see the science behind it.

In short, it aims to add a clear, public check on the science used when changing fluoride standards, which could affect what comes out of your tap and how local water systems set treatment levels.

• Who is affected: Communities served by public water systems; EPA; the National Academies.
• What changes: Any proposed fluoride limit must get a 90–180 day rapid evidence review; EPA must share its data, consider the review, and publish the full review with the proposal.
• When: Before the EPA publishes any proposed rule on fluoride levels in the Federal Register; EPA can use existing funds to do this.
