(The Last American Vagabond) On Friday, the Environmental Protection Agency officially appealed a federal court ruling which ordered the agency to take action against the risks posed by fluoridation chemicals.

The EPA staked their appeal on three main arguments, including a belief that the plaintiffs' lack standing, the judge improperly considered new evidence, and the district court went beyond its authority in its management of the case.

The EPA's appeal is the latest development in a nearly decade-long legal saga between the EPA, and parents of children impacted by water fluoridation, as well as the Fluoride Action Network (FAN). The lawsuit began following the EPA's 2016 decision to deny the plaintiff's petition under the Toxic Substances Control Act (TSCA). In September 2024, Judge Edward Chen found that fluoridation of water at 0.7 milligram per liter "poses an unreasonable risk of reduced IQ in children".
