Engineers at the University of British Columbia have developed a new water treatment that removes “forever chemicals” from drinking water safely, efficiently – and for good. “Think Brita filter, but a thousand times better,” says UBC chemical and biological engineering professor Dr. Madjid Mohseni, who developed the technology. Forever chemicals, formally known as PFAS (per-and polyfluoroalkyl substances) are a large group of substances that make certain products non-stick or stain-resistant. There are more than 4,700 PFAS in use, mostly in raingear, non-stick cookware, stain repellents and firefighting foam. Research links these chemicals to a wide range of health problems including hormonal disruption, cardiovascular disease, developmental delays and cancer.
