Potentially toxic chemicals called PFAS (perfluoroalkyl and polyfluoroalkyl substances) are found in surface and groundwaters around the world at levels much higher than many international regulators allow, a new study found.

Called “forever chemicals” because they fail to break down fully in the environment, PFAS have been used since the 1950s to make consumer products nonstick, oil- and water-repellent and resistant to temperature change.

Even in locations with no known source of contamination, 31% of ground water samples exceeded threshold limits proposed in March 2023 by the US Environmental Protection Agency, according to the study, and nearly 70% exceeded standards set by Health Canada.
