House Bill 898, sponsored by Darby, amends Tennessee Code Annotated to establish new requirements for utility systems regarding the sale of fluoridated water. Specifically, the bill mandates that each utility system must obtain a certificate of analysis for any water that contains fluoride. Additionally, the utility system is required to post both the certificate of analysis and the material safety data sheet for fluoride on its own website, or on the board of utility regulation's website if the utility does not have a website.

The bill is set to take effect on July 1, 2025, emphasizing the importance of transparency and safety in the management of fluoridated water supplies. This legislative change aims to ensure that consumers have access to critical information regarding the fluoride content in their drinking water.
