A water treatment plant in Tucson is replacing more than 56 tons of activated carbon to address newly-discovered perfluorinated compound contamination from the nearby Superfund site. “The fact that we have a treatment plant there at all is entirely driven by the Superfund site,” said Tim Thomure, director of Tucson Water.
