A new peer-reviewed study from the Environmental Working Group finds that advanced PFAS filtration systems not only remove toxic "forever chemicals" from drinking water but also significantly reduce other harmful contaminants. These include cancer-linked disinfection byproducts, agricultural nitrates, and heavy metals like arsenic and uranium. The study, published in ACS ES&T Water, analyzed data from 19 U.S. utilities and the EPA’s national monitoring program, showing that technologies like granular activated carbon, ion exchange, and reverse osmosis offer broader public health benefits than previously recognized.
