WEST ROCKHILL TWP., Pa. - The Pennsylvania Department of Environmental Protection has identified the source of chemicals that contaminated some wells in Bucks County.

The DEP has been looking into water contamination linked to chemicals known as PFAS in West and East Rockhill townships.

In this case, investigators were focusing on a site on Bethlehem Pike in West Rockhill.

They say they discovered there was a tire fire there back in 1986. That fire was extinguished with toxic firefighting foam.

The DEP named the property owner, Bergey's, as a potentially responsible entity under the Pennsylvania Hazarous Sites Cleanup Act of 1988.

The DEP says it will work with Bergey's to figure out the next steps when it comes to additional testing and remediation.
