Regulation & Litigation

  • Regulation

    As awareness about PFAS grows, more states and lawmakers are taking a closer look at the nature of these compounds and where they are present in the environment and people. Currently, there are no federal drinking water regulatory limits for PFAS compounds. What is in place is a federal, non-enforceable drinking water lifetime advisory level of 70 parts per trillion (ppt) for PFOA and PFOS. In the absence of federal regulatory limits, some states have set or have begun the process of setting their own limits based upon varying factors. Though approaches and assumptions vary, they are typically based on animal studies.  

    Existing drinking water advisory levels in many other countries are dramatically different from those of the U.S. EPA and individual states. For instance, Canada advises levels at 600 ppt and 200 ppt for PFOS and PFOA, respectively. Australia’s levels are 70 ppt and 560 ppt, and the United Kingdom recommends 300 ppt and 1,000 ppt for PFOS and PFOA.  It is important to keep in mind that the levels in the United States do not establish the dividing lines between so called “safe” and “unsafe” levels of any PFAS. The levels are meant to consider a lifetime of drinking water consumption, and they are designed to provide a large margin of protection.

  • In February of 2019, the U.S. Environmental Protection Agency presented a PFAS Action Plan to determine whether a need exists to set enforceable drinking water limits for PFOA and PFOS. 

    3M supports the U.S. EPA’s creation of a PFAS Action Plan. We support regulation rooted in sound science and believe appropriate federal regulation will help prevent a patchwork of state standards that could increase confusion and uncertainty for communities. We believe the professional scientists at the U.S. EPA should base decisions on sound science and follow established regulatory processes to safeguard the integrity of the regulatory process. Moreover, they can and should act swiftly, which is why we support calls for a clearly-defined timeline for the U.S. EPA to publish its determination on an enforceable, national standard for PFOA and PFOS in drinking water.

    3M is committed to working with the U.S. EPA, state regulatory agencies, community groups and elected officials to support continued testing to give Americans confidence in their drinking water.

  • Litigation

    3M currently is defending lawsuits concerning various PFAS-related products and chemistries. We regularly update the status of our litigation cases in our quarterly SEC filings. 3M acted responsibly with our products containing PFAS, and we will vigorously defend our record of environmental stewardship. The weight of scientific evidence over decades of research does not show that PFOA or PFOS causes harm in people at current or past levels.
