PFAS chemicals are turning up in tap water across the country. How do we get them out?

Removing “forever” chemicals from drinking water is not an easy task

Eliminating PFAS contamination from drinking water sources is “going to be a tough one to crack,” says Minnesota Department of Health hydrogeologist Ginny Yingling. Photo courtesy Minnesota Department of Health
Wright State University scientist Abinash Agrawal says destroying PFAS in water is safer than removing it and ensures that the compounds don’t pose future risks. Photo courtesy of Wright State University

This graphic illustrates how PlumeStop works in situ to remove PFAS. The substance is pumped into the aquifer through holes drilled into the ground. As the substance reaches the aquifer, gravity moves the PlumeStop around, causing the substance to stick to the aquifer’s surface, and forming a permeable water treatment zone. The PlumeStop then acts like a filter, and purifies the water moving through that area of the aquifer. Courtesy of Regenesis
