PFAS Observer
Maryland has filed suit against W.L. Gore & Associates (Gore), a downstream user of PFAS-containing materials, alleging that its manufacturing processes contributed to PFAS contamination through its use of polytetrafluoroethylene (PTFE), including Teflon®-branded PTFE. The complaint asserts that Gore sourced PTFE from E.I. DuPont de Nemours and Company (DuPont) and Chemours Company—two PFAS manufacturers already facing lawsuits from Maryland—and used it to manufacture expanded PTFE (ePTFE), a microporous material incorporated into various products, including GORE-TEX® breathable, water-resistant fabrics used in outdoor and athletic apparel.
