Fluoride chemicals added to NYC's water supply were never safety-tested and are lead- and arsenic-laced industrial waste-products (hydrofluosiclicic acid). Fluoride overdose is rampant, discoloring children's teeth necessitating warnings by government health officials to avoid mixing fluoridated water with infant formula. Modern science indicates that ingesting fluoride does not reduce tooth decay and is harmful to health making water fluoridation a complete waste of taxpayers' money.
