July 1, 2020. After Prof. Steve Gold and co-author Wendy Wagner of the University of Texas published their June 5 Policy Forum in Science, highlighting deficiencies in chemical regulation in the United States and the European Union, they were invited to present their work on the July 1 “PFAS Science and Policy” teleconference hosted by the Green Science Policy Institute. “PFAS” stands for “per- and poly-fluorinated alkyl substances,” a category that includes the chemical PFOA that was the subject of the lawsuit described in the film Dark Waters. PFOA has been phased out in the United States, but the new chemicals that have replaced it have been found in New Jersey’s environment and elsewhere. Gold and Wagner pointed out in their paper that, because of weaknesses in the regulatory system, the public has virtually no information about whether some of these substitute chemicals may be toxic.
