New laboratory tests commissioned by the Environmental Working Group found four water filters that reduce the detected “forever chemicals” known as PFAS in sampled drinking water by nearly 100 percent.

The results come as the U.S. Geological Survey announced alarming findings that almost half of the nation’s tap water has been contaminated by one or more of the 32 individual PFAS for which the agency tested. The pervasiveness of these hazardous substances in our drinking water highlights the urgent need for effective filtration solutions.

Tune in as we talk with Sydney Evans, a science analyst at Environmental Working Group (EWG) who led the water filter testing project.
