Essential Timeline of PFAS Contamination Events

Key Developments and Settlement Details

Navigating Uncertainty: The Evolving Landscape of PFAS Litigation and Environmental Regulation 

 As environmental litigation gains momentum across the country, particularly around PFAS contamination, legal practitioners and corporate stakeholders alike are facing a shifting regulatory and scientific terrain marked by uncertainty, evolving risk standards, and increasing public scrutiny. 

 A Patchwork of Regulation and Risk 

 The lack of regulatory uniformity between states continues to challenge firms and agencies. With the federal government releasing executive orders and relying on foundational statutes like the Clean Water Act and Clean Air Act, the direction remains unclear. Cases such as Sackett v. EPA have further complicated interpretations of federal authority, leaving state agencies and businesses navigating a fractured compliance environment. 

 States are becoming more risk-averse, prompting stakeholders to reevaluate the course and expectations set for clients. Each state’s approach to risk-based guidance varies, and the absence of collaboration between federal and state governments has only added to the confusion. This fragmented landscape demands that firms remain nimble and proactive in their strategies. 

 PFAS and the Rise of AFFF Litigation 

 The spotlight remains on PFAS chemicals and AFFF (aqueous film-forming foam) used in firefighting, with growing concern over the environmental and health risks associated with their widespread use. In mid-April, a number of executive orders impacting the evolving legal landscape were issued, and “Science Day” in the AFFF litigation is scheduled June 20, 2025, which will likely shape upcoming arguments with its focus on the scientific underpinnings of PFAS-related claims. The first bellwether trial is scheduled for October 20, 2025. 

The reliance on federal counterparts for science-based decision-making highlights both the importance—and current limitations—of centralized guidance. The absence of a coordinated framework hampers enforcement and puts added pressure on individual states to define their own policies. 

 Mass Tort Potential and Environmental Justice 

As enforcement actions decline and oversight continues to erode, plaintiffs’ firms are paying attention to the increasing mass tort potential. A deteriorating environmental landscape, combined with lack of remediation and regulatory stagnation, heightens third-party ring to liability and opens the door for large-scale litigation. 

 In places like New Jersey, where environmental justice has become a priority, the void of meaningful progress reflects a national challenge: ensuring environmental policies keep pace with scientific and legal realities. 

 Where Do We Go From Here? 

 Legal teams must remain alert to emerging federal and state policies, scientific updates, and public sentiment. A coordinated litigation strategy rooted in science, regulatory knowledge, and risk communication is no longer optional—it’s critical. 

 3M’s $10.3 Billion PFAS Settlement

On June 22, 3M Co. reached a significant settlement agreement to address PFAS contamination in U.S. drinking water systems. This settlement, valued between $10.3 billion and $12.5 billion, aims to resolve thousands of lawsuits alleging that 3M’s products contaminated public water supplies with “forever chemicals.” The funds will be distributed over 13 years, supporting affected communities with water filtration and testing. This settlement resolves current and future claims, divided into two phases: compensating systems with existing PFAS detections and addressing future detections.

EPA’s Stricter PFAS Health Advisories

The EPA has revised its health advisories for PFAS, reflecting new scientific research. The new guidelines indicate that there is effectively no safe level of PFOA and PFOS in drinking water. These “forever chemicals” pose significant health risks, including cancer, liver damage, and developmental issues.

The EPA has also announced plans to propose national drinking water regulations for PFOA and PFOS, with a final determination expected in the coming years.

Ongoing Litigation and Manufacturer Accountability

In addition to 3M, other manufacturers like DuPont, Corteva, and Chemours have committed billions to resolve PFAS liabilities. Litigation continues across the U.S., with states and municipalities seeking to hold manufacturers accountable for the widespread contamination.

The Potential Hazard of “Forever Chemicals”

PFAS, known as “forever chemicals,” pose a significant environmental and public health threat. These substances are highly persistent, accumulating in the environment and human bodies. Exposure to PFAS has been linked to various health issues, including cancer, liver damage, and immune system effects.
