Everything you need to know about the chemical one White House aide called a ‘public relations nightmare’

Local, state, and tribal regulators met with the Environmental Protection Agency May 22 and 23 for a national two-day summit on how to limit a class of groundwater contaminants so pervasive, they can be found in the bloodstream of most Americans.

However, it was the agency's exclusion of reporters, community groups, and at least one Congressman that made the news. Reporters from the Associated Press, CNN, and environment and energy news network E&E were initially barred from entering the room on the first day of the meeting hosted by the EPA at its Washington D.C. headquarters. The agency also failed to invite most community groups representing local residents exposed to the toxic chemicals being discussed.

When members of the press were turned away again on day two of the meeting, this only added to the agency’s secretive stance toward a group of toxic “forever” chemicals that build up in the human body, known collectively as poly- and perfluoroalkyl substances (PFAS).
