A major problem confronting the United States in the 21st century is the 20th century's legacy of toxic waste. The weapons that fought the Cold War, the facilities that manufactured those weapons, and the factories that fueled a prosperous economy left behind a trail of pollution. Seven previously unpublished essays examine the problem of toxic waste in the United States, what is being done about it, and what should be done about it. W. Henry Lambright and Agnes Gereben Schaefer, Dianne Rahm, Sevim Ahmedov, Charles Davis, Robert A. Simons and Kimberly Winson, Santa Falcone, and Toddi A. Steelman and JoAnn Carmin write about such issues as community based environmental management, regional EPA offices and the regulation of hazardous wastes, ""brownfields,"" nuclear and chemical weapons destruction, environmental contamination and the nuclear weapons complex, the privatization of nuclear waste clean-up, and WIPP, Yucca, and hazardous waste transport. The future of humanity demands careful thought about these matters.
