Rouda plans a third hearing for Sept. 10 and is asking 3M and DuPont to send representatives to testify. For decades, Americans have been drinking perfluorooctanesulfonic acid (PFOS), which 3M once made, and perfluorooctanoic acid (PFOA), which 3M and DuPont formerly produced, Rouda said at the July hearing. “It’s time for responsibility
