CNN —Almost half of the tap water in the United States is contaminated with chemicals known as “forever chemicals,” according to a study from the US Geological Survey.
Experts say it’s important for people to understand their risk of exposure through tap water.
Water filters may help somewhat if tap water is contaminated, and there are moves to regulate some PFAS chemicals in US drinking water.
This US Geological Survey map shows the number of PFAS detected in tap water samples from select sites across the nation.
In August 2023, the EPA said it is conducting the “most comprehensive monitoring effort for PFAS ever” at large and midsize public water systems and hundreds of small water systems.
