The Department of Defense asked the Environmental Protection Agency to establish a groundwater cleanup standard for PFASs that is more than five times the EPA's current health advisory, Sen. Tom Carper, D-Delaware, wrote March 13.

Carper said he had learned the DoD, NASA and the Small Business Administration had asked the EPA to establish a groundwater cleanup standard of 400 parts per trillion for PFOA and PFOS, two types of PFASs, a class of toxic, man-made chemicals present in military fire-fighting foam and household items. The EPA's drinking water health advisory for those chemicals is 70 ppt.

The groundwater cleanup standards were supposed to be released in the fall, but have been held at the Office of Management and Budget for months.

A higher limit is unlikely to impact cleanup efforts in Fountain and Security/Widefield, where untreated wells were found just last year to have levels of combined PFOA and PFOS between 0 and 870 ppt.
