Those tests were not mandatory and there is no indication that they were carried out. scientists recommended additional testing. scientists pointed to preliminary evidence that, under some conditions, the chemicals could “degrade in the environment” into substances akin to PFOA, a kind of PFAS chemical, and could “persist in the environment” and “be toxic to people, wild mammals, and birds.” The E.P.A. In a consent order issued for the three chemicals on Oct. The records, obtained under the Freedom of Information Act by a nonprofit group, Physicians for Social Responsibility, are among the first public indications that PFAS, long-lasting compounds also known as “forever chemicals,” may be present in the fluids used during drilling and hydraulic fracturing, or fracking. The E.P.A.’s approval of the three chemicals wasn’t previously publicly known. in 2011 approved the use of these chemicals, used to ease the flow of oil from the ground, despite the agency’s own grave concerns about their toxicity, according to the documents, which were reviewed by The New York Times. For much of the past decade, oil companies engaged in drilling and fracking have been allowed to pump into the ground chemicals that, over time, can break down into toxic substances known as PFAS - a class of long-lasting compounds known to pose a threat to people and wildlife - according to internal documents from the Environmental Protection Agency.
