Concern is growing over PFAS, which have contaminated water in hundreds of communities
The Environmental Protection Agency on Tuesday proposed the first federal limits on so-called forever chemicals in public drinking water, a move that is expected to cost water utilities billions of dollars to filter out substances that have contaminated the water supplies of millions of people.
The EPA is proposing maximum allowable levels for two compounds in a class of chemicals known as perfluoroalkyl and polyfluoroalkyl substances, or PFAS. Known as forever chemicals because they take a long time to break down, they were used for decades in carpeting, clothing, food packaging, firefighting foam and other consumer and industrial products.
