Rainwater unsafe to drink due to chemicals – study

(UPDATED) STOCKHOLM: Rainwater everywhere on the planet is unsafe to drink due to levels of toxic chemicals known as PFAS that exceed the latest guidelines, a new study by Stockholm University scientists said.

Commonly known as "forever chemicals" because they disintegrate extremely slowly, PFAS (per- and polyfluoroalkyl substances) were initially found in packaging, shampoo or makeup but have spread to the entire environment, including water and air.
