Waste

Are fluorides used to fluoridate water supplies a waste product of the phosphate fertilizer industry and aluminum manufacturing industries?  No.

Fluorides used to fluoridate water supplies are a by-product of the phosphate fertilizer industry, as are many products in use today. The aluminum industry is a consumer of fluoride, not a producer. The fluoride from the phosphate fertilizer industry is a naturally occurring constituent of the phosphate rock and is recovered during the production of the phosphate fertilizer (Sanders, 1996).
