  • Commentary: What ‘Dark Waters’ reveals about corporate science


    2 Dec 2019 | Chicago Tribune

    When government agencies consider potentially harmful exposures and activities... they should insist the regulated industries... be required to pay for the research, but the studies... be conducted by scientists without conflicts of interest, under provisions that ensure their complete independence.

  • What ‘Dark Waters’ reveals about corporate science


    26 Nov 2019 | Bloomberg Opinion

    When the first public concerns abound the compound emerged, DuPont did what too many corporations do: They took a page from Big Tobacco’s playbook and hired a firm to sow doubt about the scientific evidence.

  • Top U.S. toxicologist was barred from saying PFAS cause disease in humans. She’s saying it now


    24 Oct 2019 | The Intercept

    “I was banned from doing it,” said Birnbaum. “I had to use ‘association’ all the time. If I was talking about human data or impacts on people, I had to always say there was an association with a laundry list of effects.”

  • 10 toxic ‘forever chemicals’ found in Louisville, KY, tap water


    22 Oct 2019 | EWG News

    The highest level of any single PFAS detected in the EWG sample collected in Louisville was 22 ppt of a compound known as GenX. It is a replacement chemical for PFOA, which was used to make Teflon before U.S. manufacturers phased it out of production under pressure from the EPA. The EPA’s research has found that GenX is nearly as toxic as the PFOA it replaced, and DuPont, its original manufacturer, has provided test results to the EPA showing that GenX caused cancer in lab animals.

    17 Oct 2019 | Science Magazine

    PFAS "make dioxin look easy. There are 5000 and the number keeps growing. There are multiple nuclear receptors which can be impacted by PFAS. There are also many other pathways that are affected. Of the thousands of PFAS, really, there’s only a fair amount of data on two of them."

  • Toxic PFAS chemicals found in artificial turf


    8 Oct 2019 | The Intercept

    PFAS chemicals have been identified in synthetic turf, according to lab tests performed on several samples of the artificial grass that were shared with The Intercept. The presence of the chemicals, members of a class that has been associated with multiple health problems, including cancer, adds to growing concerns about the grass replacement that covers many thousands of acres in parks, schools, professional sports stadiums, and practice fields around the U.S.

  • EPA: 3M discharged chemicals without required permit, took years to disclose reporting errors


    26 Sep 2019 | WHNT News 19

    A U.S. EPA inspection report found high levels of perfluorinated chemicals from discharge sites, noted 3M lacks a state discharge permit for a chemical that it's already been discharging and pointed out 3M waited three years to inform regulators about hundreds of instances of incorrect discharge information it had filed.

  • Trump threatens to veto first ever Congressional Action on ‘forever chemicals’


    22 Sep 2019 | Truthout

  • EPA allowed companies to make 40 new PFAS chemicals despite serious risks


    19 Sep 2019 | The Intercept

    Despite their dangers, at least 15 of these 40 PFAS compounds that were the subject of substantial risk reports are not only on the most recent list of compounds in active use but also are produced in very large quantities.

  • EPA refuses to promise federal limit on PFOA exposure


    18 Sep 2019 | Times Union

  • Concerns rise over tainted sewage sludge spread on croplands


    12 Sep 2019 | Associated Press

    Several states are examining sewage sludge for PFAS contamination and assessing potential dangers. Maine has enacted a nonbinding advisory level for PFAS in sludge and New Hampshire is working with the U.S. Geological Survey on a soil study whose results will help them set a standard. Maine also found most biosolids from more than 30 wastewater treatment plants were above the state's advisory level while neighboring New Hampshire detected PFAS in tests of sludge from two dozen permit holders. Neither state found traceable levels of PFAS in the milk tested. Based on sludge tests at 41 plants, Michigan ordered several to stop distributing it to farms.
