The half-acre Neal�s Dump (Spencer) site is located near Spencer in Owen County, Indiana. The area was a disposal site for industrial wastes from about 1966 to 1971. Contract waste haulers dumped electrical capacitors containing polychlorinated biphenyls (PCBs), capacitor parts, PCB-contaminated rags and sawdust at the site, leading to groundwater contamination. The PCB-contaminated wastes came from an electrical equipment plant owned by the Westinghouse Electric Corporation (formerly Viacom and now doing business as CBS Corporation). Following cleanup, EPA took the site off the Superfund program�s National Priorities List (NPL) in 1999.
