ASHEVILLE, N.C. -- You could call congressional candidate Tate MacQueen the anti-U.S. EPA environmentalist. For nearly a decade, MacQueen has dedicated himself to getting toxic waste left by a former electroplating facility here cleaned up. Industrial solvents, including known carcinogens, are suspected to have contaminated the groundwater, and some nearby families have suffered serious illnesses including brain tumors and cancers. MacQueen isn't just angry with the former owner of the facility, CTS Corp. The main focus of his ire is EPA, which he says has criminally mismanaged the site. He is calling for investigations and prosecutions. And tomorrow, his legal efforts against CTS will be heard by the Supreme Court.
