On November 3, the 3M Company agreed to a U.S. Environmental Protection Agency (EPA) order to sample and provide treatment to address contamination from per- and polyfluoroakyl substances (PFAS) found in drinking water in the vicinity of 3M’s Cordova, IL facility. Recent sampling results provided by 3M indicate the widespread presence of a mixture of at least 19 different PFAS chemicals in drinking water within a 3-mile radius of the Cordova facility. Given the unique circumstances affecting this community, including more than five decades of PFAS discharges and the many types of PFAS chemicals found, EPA has concluded that the situation constitutes an imminent and substantial endangerment under the federal Safe Drinking Water Act.
As part of this settlement, 3M is required to offer treatment to all private well owners within 3 miles of the facility and to the Camanche Water Supply in Iowa, in an effort to remove PFAS from the drinking water. 3M is also required to offer drinking water sampling out to 4 miles from the facility for private well owners and out to 10 miles from the facility for public water systems as well as to the Quad Cities’ public water systems, using EPA protocols and conducted under EPA oversight.
3M’s sampling of the drinking water in private wells near the facility detected a range of concentrations including: perfluorooctanoic acid (PFOA) of non-detect to 25 ppt, perfluorooctanesulfonic acid (PFOS) of non-detect to 30 ppt, hexafluoropropylene oxide dimer acid (HFPO-DA), or “GenX” of non-detect to 59 ppt, and perfluorobutane sulfunate (PFBS) of non-detect to 51 ppt. 3M did not use EPA test methods for this sampling. As a result, the order issued today requires 3M to sample these wells again following EPA test methods.
3M was one of the original companies developing and producing PFAS within the United States, and their Cordova facility operations and discharges containing PFAS chemicals date back to the 1970s. 3M’s agreement to the terms of the Order including completing the work required under EPA’s oversight is an important step to begin addressing the problem created by decades of contamination. This settlement is part of EPA’s ongoing efforts to compel major PFAS manufacturers to characterize and control ongoing releases from their facilities.
Last year, EPA launched the PFAS Strategic Roadmap, a whole-of-agency approach for addressing PFAS. The Roadmap sets timelines by which EPA plans to take specific actions and commit to new policies to safeguard public health, protect the environment, and hold polluters accountable. In the national PFAS Roadmap, EPA commits to investigate releases of PFAS and where needed require manufacturers to characterize and control their PFAS releases. In the Roadmap, EPA also commits to take swift action to address potential endangerments to public health. EPA is actively working with its state partners on this effort, which will build upon valuable work led by a number of states.
Per- and polyfluoroalkyl substances, collectively called “PFAS,” are a group of man-made chemicals that have been manufactured and used in industry and consumer products since the 1940s. There are thousands of different PFAS chemicals, some of which have been more widely used and studied than others.
