"WASHINGTON — Cleaning up and protecting U.S. drinking water from a class of toxic chemicals used in many household items could cost in the tens of billions of dollars nationally, including $2 billion for the Department of Defense alone, witnesses testified Wednesday before a House panel urging the federal government to move more quickly on the cleanup.

Rep. Harley Rouda, the California Democrat chairing the House Oversight and Reform environment subcommittee, told reporters after the hearing “it’s clear” the high costs were slowing any federal efforts to regulate and clean up the toxic chemicals, which are found in a range of goods, including nonstick pans, stain-resistant clothing, dental floss and food containers. They also are in firefighting foam used by the military to battle jet-fuel fires.

The compounds, called perfluoroalkyl and polyfluoroalkyl substances, or PFAS, have been used for decades. Water sampling shows the contaminant — also called the “forever chemicals” because they will take thousands of years to break down —has seeped into many public water systems in the United States and globally, including around military bases and industries."
