Summary: This is the story of how an obscure trade association, formed in 1944 to make standards for restaurant sanitation chemicals, grew to the point where today it has agency-like authority to approve fluoridation materials and other chemicals as safe to drink.
I refer to the National Sanitation Foundation, more commonly known as “NSF”. The EPA delegated authority to NSF to approve fluoridation materials and other additives to drinking water. NSF says on its website:
In 1988, the U.S. Environmental Protection Agency (EPA) replaced its own drinking water additives program with NSF/ANSI Standards 60 and 61, which set public health standards for all chemicals used to treat water and products coming into contact with drinking water ….
Starting in 1985 the EPA sent its experts to NSF to help them get up and running as a fluoridation approving agency. From the beginning EPA gave NSF money. EPA still gives NSF money to support NSF’s fluoride approval program.
