How to Get PFAS Out of Drinking Water—and Keep It Out
Filters in water pitchers or under-sink systems capture dangerous chemicals, only for them to be returned to the environment. A researcher from North Carolina is pioneering a new system that could get rid of forever chemicals forever.
For years, chemicals giant DuPont and the company Chemours, which it spun off in 2015, manufactured long-lasting synthetic chemicals—known as forever chemicals—that made their way into the environment in this corner of North Carolina, ultimately ending up in the Cape Fear River. Cooke explains that PFAS chemicals effortlessly move around with the water cycle, which is how they end up all over the place: “Anywhere that the wind blows and the rain falls, there is potential for these contaminants to be introduced to the environment.” Despite this, other harmful PFAS molecules still turn up in a shocking range of consumer goods, according to Tasha Stoiber, senior scientist at Environmental Working Group, a nonprofit.
