TRUST THE SCIENCE

“In a decision that could end the practice of water fluoridation in the U.S., a federal judge late Tuesday ruled that water fluoridation at current U.S. levels poses an “unreasonable risk” of reduced IQ in children.

The U.S. Environmental Protection Agency (EPA) can no longer ignore that risk, and must take regulatory action, Judge Edward Chen of the U.S. District Court of the Northern District of California wrote in the long-awaited landmark decision.

More than 200 million Americans drink water treated with fluoride at the “optimal” level of 0.7 milligrams per liter (mg/L). However, Chen ruled that a preponderance of scientific evidence shows this level of fluoride exposure may damage human health, particularly that of pregnant mothers and young children.

The verdict delivers a major blow to the EPA, public health agencies like the Centers for Disease Control and Prevention (CDC) and professional lobbying groups like the American Dental Association (ADA), which have staked their reputations on the claim that water fluoridation is one of the greatest public health achievements of the 20th century and an unqualified public good.”
