PUBLIC HEALTH: Provides relative to water fluoridation. (gov sig) (EN SEE FISC NOTE LF EX See Note)
SB 4 changes Louisiana's water fluoridation policy by ending the state mandate for fluoridation in public water systems. Instead, it requires local voter approval via election for any system to fluoridate, with exceptions for systems already meeting natural fluoride levels. This directly affects public water systems serving over 5,000 connections that currently fluoridate or need to adjust fluoride levels. The bill takes effect January 1, 2027, replacing the previous requirement with a local decision process.

MINOR
The bill was converted from a draft proposal to an enrolled Act, changing its status from pending legislation to law. The sponsors were expanded to include multiple representatives, and the effective date was removed, allowing the law to take effect immediately upon the governor's signature. The substantive text of the fluoridation requirements appears to remain consistent between the two versions.
Scope change
The bill's scope remains focused on public water systems in Louisiana, specifically those with at least 5,000 service connections and fluoride levels outside the optimal range. The primary change is the transition from a proposed bill to an enacted law.
TIMELINE
The specific effective date of January 1, 2027, found in the original draft was removed. The enrolled Act now states the law becomes effective immediately upon the governor's signature or expiration of the signing period.
SCOPE
The list of bill sponsors was expanded to include Representatives Amedee, Coates, Crews, Dickerson, Edmonston, Jackson, Mack, Owen, and Ventrella, whereas the original draft only listed Senator Fesi.
TECHNICAL
The document was formally marked as 'ENROLLED ACT No. 731' and included signatures from the President of the Senate, Speaker of the House, and the Governor, indicating final approval.
