Chemicals from firefighting foam and other sources

Back to concerns and emergencies | back to drinking water consumer information
 
 
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, and have been used for decades in many consumer products and industrial processes to repel oil and water, resist heat, and reduce friction.
 
We are still learning about health effects from exposure to these chemicals, but studies have found serious potential impacts including pregnancy complications, developmental delays in children, and increased cholesterol. Learn more about these chemicals and the department’s actions to reduce exposure below.
