Environmental groups say they plan to sue a Bethlehem landfill owner for allegedly dumping contaminants into the Ammonoosuc River.

The news comes just days before a Town Meeting vote on a plan to expand the site.

Vermont-based Casella Waste Services is dismissing the threat as a political stunt.

The announcement came from two Boston-based nonprofits – the Conservation Law Foundation and the Toxics Action Center, where Woody Little is an organizer.
