A state agency has opened the door for the dumping of what many say is a "toxic cocktail" into the water table at the unlined Springdale Pit in Coaldale, as the Pennsylvania Department of Environmental Protection approved the use of river sludge, fly ash, cement kiln dust and lime kiln dust for mine reclamation projects in Pennsylvania.

The Tamaqua-based Army for a Clean Environment believes the move has the potential to poison the environment and lead to the creation of the area's newest Superfund site, vowing legal action.
