BENNINGTON, Vt. (AP) — A judge in a class-action has allowed a company accused of contaminating private wells in Vermont to request medical records from plaintiffs.

The Bennington Banner reports U.S. District Judge Geoffrey Crawford decided to allow Saint-Gobain Performance Plastics to request 20 years of medical records from plaintiffs instead of 50.

Residents in the suit who ingested PFOA are seeking damages for the creation of a medical monitoring fund.

Saint-Gobain had argued the residents' claims are too diverse to qualify for a single class action suit.

PFOA, or perfluorooctanoic acid, has been linked to certain kinds of cancer and other illnesses. It was used at the now-closed Chemfab Corp. factory in North Bennington that is now owned by Saint-Gobain.

The company has a pending settlement with the state.
