The Washington Department of Health plans to lower the limits on “forever chemicals” in drinking water after the U.S. Environmental Protection Agency announced new lower limits on Wednesday.

The EPA released [new nationwide maximum contaminant levels](https://lnks.gd/l/eyJhbGciOiJIUzI1NiJ9.eyJidWxsZXRpbl9saW5rX2lkIjoxMDEsInVyaSI6ImJwMjpjbGljayIsInVybCI6Imh0dHBzOi8vd3d3LmVwYS5nb3YvbmV3c3JlbGVhc2VzL2JpZGVuLWhhcnJpcy1hZG1pbmlzdHJhdGlvbi1maW5hbGl6ZXMtZmlyc3QtZXZlci1uYXRpb25hbC1kcmlua2luZy13YXRlci1zdGFuZGFyZCIsImJ1bGxldGluX2lkIjoiMjAyNDA0MTAuOTMxNTgzMzEifQ.D4vyFgdG3Qn4V9-bTXRhnvaaULcUjKRAHwJizebdXkU/s/3072823994/br/240480437784-l?ref=cascadepbs.org) for per- and polyfluoroalkyl substances – known as PFAS – after a year-long review. The DOH responded to that announcement with an explanation of what those new limits will mean for Washington. The new EPA maximum levels are mostly lower than the limits adopted in 2021 by the Washington State Board of Health.

Those state limits will stay in place until the Board of Health adopts the new federal levels, which can take up to two years, according to a news release from the DOH.

PFAS are a class of water-resistant human-made chemicals used in a wide variety of products from rain jackets to Teflon pans to firefighting foam. These so-called “forever chemicals” [do not break down easily in the environment](https://crosscut.com/environment/2024/02/pfas-washingtons-well-water-could-make-you-sick?ref=cascadepbs.org). They have been found to have negative health impacts that include higher cholesterol, decreased immune response, thyroid disease and increased risks of kidney and testicular cancer.

The DOH offers a [page filled with information](https://doh.wa.gov/community-and-environment/contaminants/pfas/media-resources?ref=cascadepbs.org) about PFAS, and so do the [Centers for Disease Control and Prevention](https://www.cdc.gov/niosh/topics/pfas/default.html?ref=cascadepbs.org). Recent reporting at Cascade PBS [revealed how much of a problem](https://crosscut.com/environment/2024/02/pfas-washingtons-well-water-could-make-you-sick?ref=cascadepbs.org) these substances have been in Washington.
