People who say they were exposed to PFAS chemicals at what’s now Pease International Tradeport are suing a group of chemical companies.
The federal class-action suit was filed just days before New Hampshire sued the same companies and one other for statewide water contamination.
The suits name companies like 3M and DuPont, as well as makers of firefighting foams that contained PFAS.
The state's lawsuits are broad and don't focus on specific points of exposure, but the class-action suit is different.
It includes 21 plaintiffs who lived, worked or went to school at Pease – back when it was a military base, or more recently.
Pease was found in 2014 to have extremely high levels of PFAS in its drinking water, likely due to past military activities.
The plaintiffs in the class-action suit have medical problems that have been linked to PFAS exposure, including some cancers, high cholesterol and thyroid problems.
Like the state lawsuits, the class-action suit alleges these companies sold the chemicals despite knowing they could pose serious health risks.
Similar class-action suits to this one have been consolidated into an ongoing PFAS docket in federal court.
