NEW YORK — For about 50 years, adding cavity-preventing fluoride to drinking water was a popular public health measure in Yorktown, a leafy town north of New York City.
But in September, the town’s supervisor used his emergency powers to stop the practice.
The reason? A recent federal judge’s decision that ordered U.S. regulators to consider the risk that fluoride in water could cause lower IQ in kids.
“It’s too dangerous to look at and just say ‘Ah, screw it. We’ll keep going on,’” said the town supervisor, Ed Lachterman.
Yorktown isn’t alone. The decision to add fluoride to drinking water rests with state and local officials, and fights are cropping up nationwide.
Communities in Florida, Texas, Oregon, Utah, Wyoming and elsewhere have debated the idea in recent months — the total number is in the dozens, with several deciding to stop adding it to drinking water, according to Fluoride Action Network, an advocacy organization against water fluoridation. In Arkansas, legislators this week filed a bill to repeal the state’s fluoridation program.
The debates have been ignited or fueled by three developments:
—In August, a federal agency reported “with moderate confidence” that there is a link between high levels of fluoride exposure — more than twice the recommended limit — and lower IQ in kids.
—In September, the federal judge ordered the U.S. Environmental Protection Agency to further regulate fluoride in drinking water because high levels could pose a risk to the intellectual development of children.
—This month, just days before the election, Robert F. Kennedy Jr. declared that Donald Trump would push to remove fluoride from drinking water on his first day as president. Trump later picked Kennedy to run the Department of Health and Human Services.
In Durango, Colorado, there was an unsuccessful attempt to stop fluoridating the water during Trump’s first term in office. A new push came this year, as Trump saw a surge of political support.
“It’s just kind of the ebb and flow of politics on the national level that ultimately affects us down here,” said city spokesman Tom Sluis.
Fluoride strengthens teeth and reduces cavities by replacing minerals lost during normal wear and tear, according to the U.S. Centers for Disease Control and Prevention. In 1950, federal officials endorsed water fluoridation to prevent tooth decay, and the addition of low levels of fluoride to drinking water has long been considered one of the…
