What changed
Louisiana Senate passed SB4, a bill requiring public water systems to maintain specified fluoride levels in drinking water. The bill cleared the Senate with amendments adopted on April 8, 2026, and now proceeds to the House.
Water utilities and municipal authorities in Louisiana should monitor this legislation closely. If enacted, affected systems would need to install, maintain, or adjust fluoridation equipment to meet prescribed concentration standards. Public health authorities may see implications for community water fluoridation programs already in place.
