Federal judge orders EPA further regulate fluoride in drinking water due to concerns over lowered IQ in kids

DOES FLUORIDE IN DRINKING WATER HURT YOUR BRAIN?

In 1950, federal officials endorsed water fluoridation to prevent tooth decay, and they continued to promote it even after fluoride toothpaste brands hit the market several years later. In 1945, Grand Rapids, Michigan became the first city in the world to fluoridate its water supply. 

Critics have long said that washing teeth with fluoride is not comparable to the risks posed by ingesting fluoride, with the latter potentially triggering harmful neurotoxic effects. 

Since 2015, federal health officials have recommended a fluoridation level of 0.7 milligrams per liter of water. For five decades before that, the recommended upper range was 1.2 “after evidence increasingly established fluoride’s connection to adverse effects, including severe enamel fluorosis, risk of bone fracture, and potential skeletal fluorosis,” the judge wrote. Skeletal fluorosis is a potentially crippling disorder which causes weaker bones, stiffness and pain.

The World Health Organization has set a safe limit for fluoride in drinking water of 1.5. Separately, the EPA has a longstanding requirement that water systems cannot have more than 4 milligrams of fluoride per liter of water. 

The case was brought by Food and Water Watch, an advocacy organization which petitioned the EPA to investigate lowered IQs in children allegedly caused by fluoride. The EPA denied the group’s 2016 petition calling for the agency to ban or limit the fluoridation of drinking water. 

Food & Water Watch and several co-petitioners subsequently sued the EPA to compel action citing the mounting scientific evidence of toxicity when fluoride is ingested.

“Today’s ruling represents an important acknowledgment of a large and growing body of science indicating serious human health risks associated with fluoridated drinking water,” the group said in a statement.

“This court looked at the science and acted accordingly. Now the EPA must respond by implementing new regulations that adequately protect all Americans – especially our most vulnerable infants and children – from this known health threat.”

Tuesday’s ruling cited a review of 72 human epidemiological studies and available literature by the U.S. National Toxicology Program which concluded that fluoride is connected to reduced IQ in children.

“Notwithstanding recognition by EPA’s expert that fluoride is hazardous, the EPA points to technicalities at various steps of the risk evaluation to conclude that fluoride does not present an unreasonable risk,” Chen said. “Primarily, the EPA argues the hazard level and the precise relationship between dosage and response at lower exposure levels are not entirely clear. These arguments are not persuasive.”
