Baker v. Saint-Gobain Performance Plastics Corp. is a high-profile PFAS water contamination class action involving allegations of industrial pollution in Hoosick Falls, New York. The lawsuit centers on perfluorooctanoic acid (PFOA), a toxic chemical in the PFAS (per- and polyfluoroalkyl substances) family, and whether emissions from Saint-Gobain and Honeywell led to groundwater and air pollution. Plaintiffs seek damages for property devaluation, health risks, and remediation costs associated with exposure to so-called "forever chemicals." A $65 million settlement with Saint-Gobain, Honeywell, and 3M was reached in 2022, while claims against DuPont remain active. The case reflects broader environmental litigation trends surrounding PFAS exposure, groundwater contamination, and chemical industry accountability.
Following the detection of elevated PFOA levels in private and municipal wells in Hoosick Falls, lawsuits were filed against Saint-Gobain and Honeywell. The EPA designated the area as a hazardous site. Plaintiffs alleged that long-term industrial operations caused environmental contamination of the water supply, sparking litigation under toxic tort and environmental law doctrines.
The defendants entered into a $65 million settlement agreement addressing claims of property damage and exposure to PFOA. Funds were allocated for residential water filtration systems and compensation for property value loss. DuPont did not join the settlement and continues to face separate litigation. The agreement set a benchmark for PFAS class action settlements.
DuPont requested expanded discovery and filed motions to limit expert testimony. The court denied the discovery expansion, affirming that sufficient documentation had been produced. Challenges to expert opinions related to chemical exposure pathways and groundwater migration further illustrated the complexity of PFAS litigation procedures.
DuPont’s motion to exclude expert witness testimony under Daubert was partially granted. The court allowed testimony based on reliable environmental science methodologies while excluding others that failed to meet evidentiary standards. This ruling emphasized the role of Rule 702 in determining the admissibility of scientific evidence in environmental contamination lawsuits.
With the majority of defendants having resolved their claims, DuPont remains the sole active party. The case is currently in the expert deposition and pre-trial motion phase, with trial expected unless a separate settlement occurs. The outcome could shape future toxic tort claims involving PFAS and chemical exposure liability.

Assessed the fate and transport of PFOA in air, soil, and groundwater to trace pollution sources.
Evaluated health risks associated with chronic PFAS exposure and potential long-term effects.
Modeled groundwater movement and contaminant pathways to identify affected areas and causation.
Analyzed human exposure routes including ingestion and inhalation of contaminated water or air.
Reviewed historical emissions and waste management practices to assess regulatory compliance.
Evaluate toxic exposure and environmental contamination by identifying pollutant sources, assessing environmental pathways, and determining potential impacts.
The reliability of scientific methodology is a key factor in determining admissibility under Rule 702. Courts continue to scrutinize expert witness qualifications and methods in toxic tort and PFAS litigation.
Settlements by some defendants do not preclude continued litigation against others. Legal strategies should account for individual party liability and evidentiary separation.
Expert testimony must clearly separate economic loss (property value decline) from medical monitoring or remediation costs to support claims for distinct types of damages.
Successful toxic tort cases depend heavily on scientific evidence presented by environmental, medical, and engineering experts. Interdisciplinary collaboration is essential.
Baker v. Saint-Gobain is a significant environmental case involving alleged PFOA water pollution and legal questions surrounding chemical exposure, corporate responsibility, and the admissibility of scientific testimony. It illustrates the evolving nature of PFAS litigation and the role of environmental hazard experts in linking industrial practices to groundwater contamination. With claims against DuPont still pending, this case continues to influence strategies in environmental class actions, mass torts, and regulatory compliance litigation across the U.S.
What is PFAS and why is it dangerous?
PFAS (per- and polyfluoroalkyl substances) are synthetic compounds widely used in manufacturing that resist heat, oil, and water. They are persistent in the environment and human body and have been linked to health concerns.
Which companies are defendants in the Baker PFAS lawsuit?
Saint-Gobain, Honeywell, and 3M settled in 2022. DuPont remains a defendant as of June 2025.
Why are expert witnesses important in PFAS exposure cases?
Expert witnesses help demonstrate how PFOA may have migrated into drinking water and whether there is a scientific basis for health or economic harm.
Is PFAS litigation growing nationally?
Yes. PFAS-related lawsuits are increasing in number, targeting water utilities, chemical manufacturers, and military contractors across the U.S.
What types of damages are plaintiffs seeking?
Compensation for lost property value, installation of water filtration systems, medical surveillance, and cleanup costs.
Assessed the fate and transport of PFOA in air, soil, and groundwater to trace pollution sources.
