Chemicals from firefighting foam and other sources



Chemicals from firefighting foam and other sources


Coloradans face an emerging public health challenge from a family of chemicals found in toxic firefighting foam and other sources. The chemicals are known scientifically as per- and polyfluoroalkyl substances, or PFAS. On June 15, 2022, the Environmental Protection Agency announced an update to health advisories for four PFAS chemicals by lowering the level of acceptable amounts present in drinking water. These chemicals are known to have negative impacts on human health and the environment. Learn more about the EPA's announcement and these chemicals below.
