Both of the suspected sources of contamination were associated with the Warren Wire factory on Route 346, after Warren Wire’s Teflon-coating operation was sold to General Cable in the mid-1960s.Warren Wire operated at the Route 346 factory from the late 1940s through the mid-1960s, when the company was sold to General Cable Corp. The business there focused on coating fabrics with Teflon, which was dried in a high-temperature process.

Owners of the Warren Wire business also created ChemFab Corp. in Bennington in 1968, which produced similar Teflon-coated fabrics at two locations in that town. The state identified those ChemFab factories as the source of PFOA contamination, which, through stack emissions, was spread over a large part of Bennington.

American Premier Underwriters assumed environmental liability for the Warren Wire site when it was purchased by the current owner, Mack Molding. APU hired Unicorn Management Consultants to coordinate the company’s response to the Ponwal contamination.
