When it comes to PFAS, Birnbaum said, it’s ubiquitous and it causes a number of health impacts, including on both male and female reproduction. Linda Birnbaum, a toxicologist and the former head of the National Institute of Environmental Health Sciences, said transparency around fracking chemicals remains an issue despite the growing epidemiological evidence of impacts like low birth weight, linked to living near fracking sites. The report highlights the difficulty of trying to find out information on the substances, which are often referred to differently in disclosure reports. “EPA has concerns that these degradation products will persist in the environment, could bioaccumulate or biomagnify, and could be toxic (PBT) to people, wild mammals, and birds based on data on analog chemicals, including PFOA and. The documents revealed EPA itself had questions about the approval in 2011: The public records PSR received included thousands of heavily redacted documents, including instances where the companies redacted their own name and chemical identification, or CAS, claiming a trade secret. “We uphold longstanding procedures to transport, handle, and use chemicals safely, including well-bore integrity, chemical containment, science-based hazard assessments and other operational practices, and we will continue to use science-based measures to further protect health and safety.”

“Although PFAS is not widely used in fracking and only at extremely low levels, API will continue to review available data and analyses to better understand and mitigate the use of these chemicals across the upstream segment,” API spokeswoman Bethany Aronhalt said. The American Petroleum Institute said PFAS use is limited. The group obtained documents through a Freedom of Information Act request. The Physicians for Social Responsibility report, Fracking with “Forever Chemicals“, found evidence the substance was used in 1,200 wells in six states between 20. Studies of some of the PFAS chemicals show a link to low birth weight, pre-eclampsia and increased cholesterol exposure also causes impacts to liver, kidney and thyroid health. But use of PFAS continues, and the chemicals have been detected at concerning levels in some water supplies, especially near military installations in Pennsylvania and across the country. Some, including PFOA and PFOS, are no longer made in the U.S. They are used to make teflon, food packaging and firefighting foam. They contain strong carbon-fluorine bonds that don’t break down easily in the environment, which has garnered them the nickname “forever chemicals.” The strength of the bond makes them useful for waterproofing and stain resistance. PFAS, or per- and polyfluoroalkyl substances, are a class of 9,252 man-made chemicals, according to the EPA. The chemical disclosure requirements include the fracking process, which uses high pressure water and chemicals to break up the shale rock and release the gas. That’s because Pennsylvania’s fracking disclosure law allows exemptions for trade secrets, and does not require drillers to disclose chemicals used to drill a well. “We can’t be confident that we know everything that has been used in Pennsylvania,” Horwitt said. The report’s author, Dusty Horwitt, says that while he couldn’t find evidence the chemicals were used in Pennsylvania wells, Exxon/XTO Energy and Chevron are among the companies that have used it elsewhere.

Companies that drill for natural gas in Pennsylvania have used EPA-approved PFAS or pre-cursors to PFAS in fracking operations in other states, according to a report by Physicians for Social Responsibility.
