Regulation of Perchlorate at Low Levels in Drinking Water: A High Stakes Decision

Applications

PERCHLORATE HAS A LONG HISTORY OF USE AS A MEDICINE FOR CERTAIN THYROID GLAND DISORDERS.

Perchlorate is a salt-like substance made up of chlorine and oxygen. It is found in nature and it can be man-made. It has a long history of use as a medicine for certain thyroid gland disorders. For comparison, the dose of perchlorate used as a medicine is tens of thousands of times greater than the amounts being detected in drinking water.

Perchlorate is widely used today by the military, NASA and the commercial space industry as an ingredient in solid rocket fuels and explosives. It's also used in safety flares, fireworks, auto air bag inflators, lubricating oils and aluminum refining. Perchlorate also is naturally present in some fertilizers typically used in organic farming.
