EPA suggests tighter limits for industrial chemical in water | McClatchy DC

guidelines Thursday for human exposure to an industrial chemical used for decades in such consumer products as non-stick pans, stain-resistant carpets and microwave popcorn bags.

The cancer-causing chemical perfluorooctanoic acid, known as PFOA, has been found in the tap water of dozens of factory towns near industrial sites where it was manufactured. DuPont, 3M and other U.S. chemical companies voluntarily phased out the use of PFOA in recent years.

Also at issue is the related chemical perfluorooctane sulfonate, or PFOS, used in firefighting foam.

The Environmental Protection Agency issued the stricter guidelines for the chemicals after years of pressure from public health experts and advocacy groups. The agency said the new limits were prompted by recent scientific studies linking PFOA and PFOS to testicular and kidney cancers, as well as birth defects and liver damage.

"EPA will continue sharing the latest science and information so that state and local officials can make informed decisions and take actions to protect public health," said Joel Beauvais, the EPA's deputy assistant administrator for the Office of Water. "This is an important part of our broader effort to support states and public water systems as we work together to strengthen the safety of America's drinking water."

Trace amounts of PFOA and PFOS can be detected in the blood of almost every American as the result of exposure through food and consumer products. But of specific concern to regulators is the risk posed to residents in the relatively small number of communities where higher levels of PFOA and PFOS have been found in public drinking water.
