The St. Clair County Health Department is warning area cities with public water systems about possible changes to federal fluoride rules. Medical Director Dr. Remington Nevin says the EPA is under court order to review fluoride safety after new research linked higher exposure to potential brain-development issues. The agency could lower the national limit, now set at 0.7 parts per million. County health officials already backed a plan last fall to ban added fluoride locally, with draft rules coming soon for public comment.
