Senate rejects bill to end community water fluoridation after extended debate

The Arizona Senate considered SB 10‑19 on March 19, a measure amending statutes related to potable water systems that critics said would curtail community water fluoridation. After extended floor debate and explanations of vote, the bill failed on a recorded tally of 14 ayes, 11 nays and 5 not voting.

Senator Kubey argued against the measure, saying fluoride in community water is a safe, cost‑effective public‑health intervention that reduces tooth decay and is best decided locally: “Community water fluoridation is another layer of protection and it supports efforts,” Kubey said during an explanation of his vote.

Opponents of fluoridation who supported the bill described systemic treatment through water as involving a chemical they said poses risks and argued it denies individual informed consent. “Medicating our public without informed consent should never have been allowed,” said Senator Champ, who explained his aye vote and cited studies and a federal court ruling referenced on the floor.

Senators recounted scientific citations and policy history. The debate included exchange over public‑health benefits, differing interpretations of the scientific record and whether local governments should retain control over water‑quality decisions.

After the vote failed, the chair returned the Senate to its order of business and moved on to other agenda items.
