We are at the forefront of PFAS and environmental toxic tort litigation involving contaminated water. We are currently court-approved co-lead counsel in two of the largest PFAS and water-related toxic tort class actions in the United States: Victoria Carey, et al. v. E.I. DuPont de Nemours and The Chemours Company, et al. (E.D.N.C) and In re Flint Water Cases (E.D. Mich.).

Our goal is singular and clear -- we are dedicated to representing local communities and citizens that have been exposed to PFAS contamination.

The PFAS litigation team is ready to guide your community through the process of deciding how best to respond to the issues raised by PFAS in the water supply and how best to protect citizens.

What Are PFAS?

Per-and polyfluoroalkyl substances, or PFAS, also known as “forever chemicals,” are toxic, man-made chemicals that are being discovered in drinking water across the county. The toxic chemicals have been manufactured and used in a variety of consumer products since the 1940s.

There are several different PFAS, including PFOA, PFOS, and GenX and other replacement PFAS. Studies have found that PFOA, PFOS, and GenX have been found in drinking water due to localized contamination. Localized contamination includes:

  • Factories and manufacturing plants that make products that contain PFAS, such as cookware, stain- and water-resistant fabrics and carpeting, cleaning products, and other household and automotive products
  • Airports and military installations that use aqueous film forming foam (AFFF) firefighting foams

Exposure to PFAS chemicals can cause adverse health outcomes, including:

  • Low infant birth weight
  • Decreased fertility
  • Elevated cholesterol
  • Abnormal thyroid hormone levels
  • Liver inflammation
  • Weakening of the immune system
  • Cancer

How We Can Help

We help local communities that may have PFAS and lead contaminated drinking water fight manufacturing and chemical companies that are responsible for this life-threatening contamination.

We track and analyze all existing PFAS related litigation on a daily basis and know what issues have been litigated in other cases and what evidence has been identified and disclosed in those cases. Our team brings comprehensive resources in terms of in-house discovery, third-party environmental testing experts and regulatory teams, as well as crisis management teams. We track PFAS related actions and developments at the U.S. Environmental Protection Agency and at state environmental agencies, as well as the most recent developments related to testing and regulating PFAS compounds. We have unique insights into the roles of those agencies and their possible actions related to PFAS issues. We are frequently contacted by national environmental reporters who rely upon our legal insights on PFAS developments.

Representative Matters

Our PFAS Litigation team has extensive knowledge and expertise in litigating high-profile water, PFAS, and other environmental toxic tort lawsuits. Some of our current matters include:

  • Victoria Carey, et al. v. E.I. DuPont de Nemours and The Chemours Company, et al., No. 7:17-CV-201-D (E.D.N.C.): Cohen Milstein is Interim Co-Lead Class Counsel in this putative toxic tort class action against DuPont and its former wholly-owned subsidiary, Chemours. Since 1980, DuPont and Chemours have knowingly dumped toxic chemical byproducts into the Cape Fear River affecting potentially more than 770,000 residents in North Carolina and have lied to the U.S. Environmental Protection Agency and state regulators regarding their conduct. On April 19, 2019, the court issued an opinion denying in large part Defendants’ motion to dismiss, allowing Plaintiffs to pursue the bulk of their claims, including allowing Plaintiffs to seek damages for future medical expenses. This case has been reported in the media throughout the United States.
  • In re Flint Water Cases, No. 16-cv-10444 (E.D. Mich.): On November 18, 2020, Cohen Milstein, as Interim Co-Lead Class Counsel on behalf of Flint residents and businesses, reached an agreement for a $641.25 million settlement with multiple governmental defendants, including the State of Michigan, Michigan Department of Environmental Quality (DEQ), City of Flint and individual defendants, including former Governor Rick Snyder, in the Flint Water Crisis Litigation, affecting over 90,000 Flint residents and businesses. Litigation will continue against other defendants, including two private engineering firms, Veolia North America and Lockwood, Andrews & Newnam (LAN), both charged with professional negligence, and separate litigation against the U.S. Environmental Protection Agency will also continue.
