An Arizona bill would prohibit the use of fluoride in state public water systems. State Sen. Janae Shamp, R-Surprise, introduced Senate Bill 1019, which would prevent people and political subdivisions from adding fluoride or fluoride-containing compounds to Arizona’s public water system. The Senate Committee on Government recently advanced SB 1019 to the floor for a full Senate vote. … If SB 1019 becomes law, the Arizona Department of Environmental Quality would enforce it, Shamp told The Center Square. … If Arizona were to pass SB 1019, it would join Florida and Utah as the only states that prohibit fluoridation of their water systems.
