GAO-12-109: Published: Jan 18, 2012. Publicly Released: Feb 17, 2012.
From fiscal year 1990 through October 2010, the Environmental Protection Agencys (EPA) 10 regions collected from potentially responsible parties almost $4 billion in funds that were placed in special accounts. Nearly half of these funds are still available to be obligated for future Superfund cleanup; the remaining funds have already been obligated, but not all of these obligated funds have...
Nuclear Material: DOE's Depleted Uranium Tails Could Be a Source of Revenue for the Government
GAO-11-752T: Published: Jun 13, 2011. Publicly Released: Jun 13, 2011.
Since the 1940s, the Department of Energy (DOE) has been processing natural uranium into enriched uranium, which has a higher concentration of the isotope uranium-235 that can be used in nuclear weapons or reactors. This has resulted in over 700,000 metric tons of leftover depleted uranium, also known as "tails," that have varying residual concentrations of uranium-235. The tails are stored at DOE...
Superfund: Information on the Nature and Costs of Cleanup Activities at Three Landfills in the Gulf Coast Region

The Environmental Protection Agency (EPA) estimates that one in four Americans lives within 3 miles of a contaminated site, many of which pose serious risks to human health and the environment. The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) provided the federal government with authority to respond to releases or threatened releases of hazardous substance...
Superfund: Interagency Agreements and Improved Project Management Needed to Achieve Cleanup Progress at Key Defense Installations
GAO-10-348: Published: Jul 15, 2010. Publicly Released: Aug 16, 2010.
Before the passage of federal environmental legislation in the 1970s and 1980s, Department of Defense (DOD) activities contaminated millions of acres of soil and water on and near DOD sites. The Environmental Protection Agency (EPA) has certain oversight authorities for cleaning up contaminants on federal property, and has placed 1,620 of the most contaminated sites--including 141 DOD installation...
Superfund: Information on Cost and Other Issues Related to the Cleanup of the Federal Creosote Site
GAO-10-277: Published: Feb 25, 2010. Publicly Released: Mar 29, 2010.
In the 1990s, creosote was discovered under a residential neighborhood in Manville, New Jersey. Creosote, a mixture of chemicals, is used to preserve wood products, such as railroad ties. Some of the chemicals in creosote may cause cancer, according to the Environmental Protection Agency (EPA). EPA found that creosote from a former wood-treatment facility (known as the Federal Creosote site) had c...

GAO-10-48: Published: Nov 4, 2009. Publicly Released: Dec 2, 2009.
High-level nuclear waste--one of the nation's most hazardous substances--is accumulating at 80 sites in 35 states. The United States has generated 70,000 metric tons of nuclear waste and is expected to generate 153,000 metric tons by 2055. The Nuclear Waste Policy Act of 1982, as amended, requires the Department of Energy (DOE) to dispose of the waste in a geologic repository at Yucca Mountain, ab...
