(Clackamas, OR) -- A Superfund site in Clackamas that was cleaned once will be cleaned again. The 53-acre Northwest Pipe & Casing Superfund site is the source of a plume of chlorinated solvent contaminated groundwater. The original cleanup work didn't stop the plume of chemicals. New technology has been developed to remove the chemicals. Eleven-and-a-half million dollars from the Bipartisan Infrastructure Law will be used to design and implement one of the new technologies which should reduce the size of the chemical plume.
