The main fluoride chemical added to water (hydrofluorosilicic acid) is an industrial by-product from the phosphate fertilizer industry. Unlike the fluoride used in toothpaste, hydrofluorosilicic acid is not pharmaceutical-grade quality. It is an unpurified, industrial-grade, corrosive acid which has been linked, in several recent studies, to increased levels of lead in children’s blood.
