Read previewThe Biden administration is cracking down on toxic "forever chemicals" that are widespread in America's tap water, food, and household products. EPA also set limits for mixtures of two or more PFAS chemicals, because research shows they may have combined health impacts. "The technology is there, especially to clean up drinking water, to filter these compounds out of the water. "For too long, many people across the country have had been drinking contaminated water levels that likely impact health." The Biden administration has a broader $9 billion PFAS strategy that goes beyond drinking water, including military bases, airports, and food packaging.

Toxic PFAS, aka "forever chemicals," are in water, food, furniture, and clothes across the US. The EPA's new proposal to limit the substances in drinking water is a step in the right direction. On Tuesday the US Environmental Protection Agency proposed strict limits on six per- and polyfluoroalkyl substances (PFAS) in drinking water. The chemicals are prolific in everyday human environments — in our water, food, air, and even the dust in our homes. That means more and more of them are getting into the environment — and drinking water — every day.
Hazardous "forever chemicals" called PFAS are in most Americans' blood, and they don't break down. One simple chart shows how long PFAS last in human bodies, compared to substances like caffeine or lead. Per- and polyfluoroalkyl substances (PFAS) are a class of thousands of human-made chemicals, which are likely in your food, water, clothes, and furniture. "Once they get into your body, they stick around for a really, really long time," Carmen Messerlian, an environmental epidemiologist who studies PFAS at Harvard's TH Chan School of Public Health, told Insider. That research tells us how long PFAS can linger in our blood, compared to toxic heavy metals or everyday substances like caffeine.
The US Environmental Protection Agency just released a proposal for enforceable standards for six PFAS compounds in drinking water. The new EPA proposal would set the threshold for those two substances at 4 nanograms per liter of drinking water. It also proposes a "hazard index" to set a limit on the combined quantity of four other PFAS in drinking water: PFNA, GenX, PFBS, and PFHxS. Communities across the US have especially high PFAS contamination in their drinking water, often due to a nearby industrial or military facility. "You can't just regulate in drinking water, without addressing the other side," Sunderland said, adding that you have to "turn off the source."
