Requires public water systems and public water supply districts that intend to start or stop fluoridation of their water supply on a continuing basis to seek and receive information about the impact of fluoridation from the local health department

This bill requires public water systems and water supply districts to consult with their local health department before deciding to start or stop adding fluoride to their water supply on an ongoing basis. If a district plans to make this change, it must notify state agencies and its customers at least 90 days before any vote, using methods like mail, radio, television, or email to ensure the public is informed. The law also specifies that investor-owned water systems are responsible for covering all costs related to complying with these notification requirements. Additionally, any district that fails to follow the proper notification steps must revert its water supply to the previous fluoride level until the correct procedures are completed.
