Two separate courts have ruled that two separate groups of plaintiffs have no basis for class-action lawsuits against DuPont Co. in connection with health claims involving perfluorooctanoic acid or PFOA.
The 4th U.S. Circuit Court of Appeals in Richmond, Va., said Dec. 12 it agreed with a lower court ruling that three residents of Wood County in West Virginia had not shown sufficient evidence to warrant a class-action lawsuit.
The appellate court ruling upheld the decision of the U.S. District Court in Parkersburg, W.Va. The plaintiffs had argued that drinking water in the Parkersburg Water District was contaminated by PFOA released into the air from a DuPont plant that is five miles upstream from a well field for the water district.
In Des Moines, Iowa, U.S. District Judge Ronald Longstaff on Dec. 12 denied a request for a class-action suit by a group of plaintiffs that had alleged that Wilmington-based DuPont misled consumers about the safety of cookware coated with Teflon, which is made from PFOA.
In his opinion, Langstaff said that because the lawsuit covers cookware purchased in 23 states, it makes a class-action lawsuit ``unmanageable.''
