Chemical manufacturer 3M Co. has announced a landmark settlement of at least $10.3 billion to resolve lawsuits related to the contamination of numerous public drinking water systems across the United States. The lawsuits stem from the presence of per- and polyfluorinated substances (PFAS), commonly known as “forever chemicals,” which were used in firefighting foam and various consumer products manufactured by the company. PFAS have been linked to serious health risks and do not naturally degrade in the environment. This settlement marks a significant step toward addressing the impact of PFAS contamination on public health and water resources.

The PFAS Issue and Health Concerns:

PFAS are a class of chemicals widely utilized in nonstick and grease-resistant products, including clothing and cookware. Due to their persistence in the environment, these compounds have been found in varying levels in drinking water systems throughout the nation. Studies have associated PFAS exposure with a range of health issues, such as liver and immune-system damage, as well as certain cancers. Recognizing the urgency of the situation, the Environmental Protection Agency (EPA) proposed strict limits on PFOA and PFOS, two common types of PFAS, and expressed its intention to regulate four additional types.

3M’s Response and Commitments:

3M’s chairman, Mike Roman, hailed the settlement as “an important step forward” in the company’s ongoing efforts to address the PFAS issue. In 2020, 3M made the decision to phase out the production of PFOA and PFOS, while investing in state-of-the-art water filtration technology for its chemical manufacturing operations. As part of the settlement, 3M has committed to ceasing all PFAS production by the end of 2025. These measures demonstrate the company’s dedication to addressing the environmental and public health concerns associated with PFAS contamination.

Terms of the Settlement:

The settlement agreement, subject to court approval, will be paid over a span of 13 years and could potentially amount to $12.5 billion. The final sum will depend on the number of public water systems that detect PFAS during testing mandated by the EPA over the next three years. The funds allocated through this settlement will aid water providers in covering the costs associated with filtering PFAS from contaminated systems and conducting further testing. By mitigating the presence of PFAS in drinking water, this agreement aims to improve the health and well-being of millions of Americans.

The Scope of the Issue and Collaborative Efforts:

The litigation surrounding PFAS contamination extends beyond 3M, with other companies, including DuPont de Nemours Inc., Chemours Co., and Corteva Inc., also reaching a $1.18 billion settlement with approximately 300 drinking water providers. Various states, airports, firefighter training facilities, and private well owners have initiated lawsuits as well. These cases are being handled by Judge Richard Gergel in the U.S. District Court in Charleston, South Carolina. The involvement of multiple stakeholders reflects the collaborative approach being taken to address the widespread problem of PFAS contamination.


The $10.3 billion settlement by 3M Co. to resolve PFAS contamination lawsuits represents a significant step toward rectifying the environmental and public health concerns associated with these persistent chemicals. By compensating water providers and investing in filtration technologies, 3M is taking responsibility for its role in the widespread presence of PFAS in drinking water systems. As more stakeholders come together to address this issue, it is hoped that these actions will pave the way for a healthier future, free from the harmful effects of PFAS contamination in public water supplies.
