Press Release

Washington, D.C. (Sept.11, 2019)— Rep. Harley Rouda, the Chairman of the Subcommittee on Environment, held a hearing on “The Devil They Knew: PFAS Contamination and the Need for Corporate Accountability, Part III.”


  • Former Minnesota Attorney General Lori Swanson testified that 3M has known about the health dangers of PFAS chemicals since the 1950s, and actively concealed that information from consumers and the EPA.  Rob Bilott, an attorney who has represented people effected by PFAS contamination, detailed what DuPont knew about the health risks associated with PFAS for decades and the company’s efforts to conceal this information from the public. 
  • Despite decades of research from their own scientists that linked PFAS chemicals to negative health consequences, 3M testified that there is “no cause and effect” between PFAS chemicals and adverse health impacts. DuPont, however, affirmed its support for designating PFOA and PFOS, two notorious long-chain PFAS chemicals, as hazardous substances under the Superfund law, while 3M declined to do so.
  • DuPont, 3M, and Chemours all refused to commit to compensate victims who have been harmed by PFAS chemicals.
  • Lawmakers pressed DuPont, 3M, and Chemours on the designation of PFAS chemicals, including PFOA and PFOS, as hazardous substances under the Superfund law.
