Mrs. Firman doesn't live in Port Angeles, or even on the Olympic Peninsula. She lives and works in Seattle, where she is employed by Delta Dental, an "insurance company" that sells fluoride, usually by providing the equipment to meter it into community water systems "free", on the condition that if said community terminates fluoridation before ten years are up, the people of the affected city will be charged for that equipment. Fluoride is highly corrosive though, and who is responsible for costs of repair and replacement of that equipment after ten years is unclear. What is clear is that Mrs. Firman and her employer have a financial interest in fluoridation that should give all affected citizens reason to question her opinions as unbiased. She and her employer are profiting handsomely from fluoridation.
