Prior to the 1980s and the passage of environmental legislation regulating the generation, storage, and disposal of hazardous waste, Department of Defense (DOD) activities and industrial facilities contaminated millions of acres of soil and water on and near DOD sites in the United States and its territories. DOD installations generate hazardous wastes primarily through industrial operations to repair and maintain military equipment. Manufacturing and testing weapons at Army ammunition plants and proving grounds have caused some serious contamination problems as well. This book examines the background and issues of contaminated Department of Defense sites across the United States and the issues for the EPA in enforcing and reporting these sites to achieve cleanup progress at these key defence installations.
