Two environmental groups of western Pennsylvania, USA, have sued a company that disposed of toxic wastes at community dumpsites, contaminating wells and hurting property values. The groups are suing Beazer East, which acquired Koppers Co -- the offender. Koppers Co is the owner of an adhesives plant located just north of Pittsburgh.
The lawsuit accuses the company of dumping wastes from the plant at several sites without adequate protection to prevent pollutants from seeping into groundwater and into the tributary of a nearby creek. State officials said tests on the water showed the presence of sulfonic acid, a by-product of manufacturing petroleum products, and resorcinol, an adhesive material produced by Koppers.
