complex tort litigation | ENVIRoNMENTAL TOXIC TORTS

Righting environmental harms today and for tomorrow.

When powerful companies contaminate your water or soil, expose you to dangerous chemicals, or damage your property due to environmental negligence, we are committed to helping you secure a measure of justice.


We represent individuals across the United States who have been injured due to exposure to toxic or potentially toxic substances, including purportedly safe substances that may have been released into the environment at toxic levels or substances that may have been improperly labelled. We have dealt with numerous types of chemicals, lead and other alloys, and chemical compound derivatives in our cases. We have extensive experience working with state and federal environmental protection agencies to address toxins in drinking water, ground water, soil, and air. We also work with subject matter experts on scientific, environmental, medical, and property value issues.  

We are frequently appointed by courts as lead or co-lead counsel to oversee large class or mass actions. Our experience includes handling two of the largest water contamination class action lawsuits in the United States—In re Flint Water Cases, and Carey, et al., v. E.I. DuPont De Nemours and Co., Inc. We have also successfully litigated toxic tort mass actions in jury trials.

We litigate all types of environmental toxic tort lawsuits, including class actions, before juries and appellate courts, including those that involve:

  • Contamination of water, including drinking and ground water
  • Pesticide and herbicide aerial drift
  • Chemical exposure, waste spills and seepage
  • Landfill, dumpsite, power plant, industrial odor, gas, ash and dust drift

PFAS Water Litigation

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 represent local communities and citizens that have been exposed to PFAS contamination. Our PFAS litigation team is ready to guide your community through the process of determining how best to respond to the issues raised by PFAS in the water supply and how best to protect citizens.


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

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.

Past Cases

Quinteros, et al. v. DynCorp, et al.

Quinteros, et al. v. DynCorp, et al. (D.D.C.): Cohen Milstein represented over 2,000 Ecuadorian farmers and their families who suffered physical injuries and property damage as a result of aerial spraying of toxic herbicides on or near their land by DynCorp, a U.S. government contractor. A bellwether trial on behalf of the first six Ecuadorian clients came to a conclusion in April 2017, when the ten-person jury unanimously determined that DynCorp was responsible for the conduct of the pilots with whom it had subcontracted to conduct the chemical spraying after April 2003. This resolution allowed for a successful case settlement.
