Groups calling to have PFAS listed as hazardous chemicals by the EPA
News
15 Jan 2020 | KTUU-TV
Listing under RCRA will subject the chemicals to strict storage, transfer, and disposal requirements. It would also result in the automatic designation of these chemicals as hazardous substances under the federal Superfund law, unlocking clean-up dollars to address contaminated sites.

As more PFAS contamination is found, federal action becomes more urgent
News
15 Jan 2020 | BDN
As we’ve learned from the containment and removal of other hazardous substances, costs only grow as action is delayed.

House passes sweeping bill to target spread of toxic ‘forever chemicals’
News
10 Jan 2020 | The Hill
Under the bill the EPA would be required to set a mandatory drinking water standard for PFAS. The bill includes a number of other measures that would further regulate PFAS, including requiring PFAS to be covered under the hazardous waste cleanup law, and imposes a five-year moratorium on the development of new PFAS chemicals.
