Federal agencies implementing the 2008 5-year plan, including the Environmental Protection Agency (EPA), the Department of Energy, the Bureau of Indian Affairs (BIA), and the Indian Health Service, met the targets in six of the plan's eight objectives, working in cooperation with tribal agencies, including the Navajo Nation Environmental Protection Agency. Reasons agencies met the targets were pri...
Hazardous Waste: Early Goals Have Been Met in EPA's Corrective Action Program, but Resource and Technical Challenges Will Constrain Future Progress
GAO-11-514: Published: Jul 22, 2011. Publicly Released: Aug 25, 2011.
Years of industrial development generated hazardous waste that, when improperly disposed of, poses risks to human health and the environment. To mitigate these risks, Congress passed the Resource Conservation and Recovery Act of 1976 (RCRA). Subtitle C of RCRA, as amended, requires owners or operators to take corrective actions to clean up contamination at facilities that treat, store, or dispose...
Superfund: Information on the Nature and Costs of Cleanup Activities at Three Landfills in the Gulf Coast Region
GAO-11-287R: Published: Feb 18, 2011. Publicly Released: Feb 18, 2011.
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

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...
Coal Combustion Residue: Status of EPA's Efforts to Regulate Disposal

On December 22, 2008, a breach in a surface impoundment (or storage pond) dike at the Tennessee Valley Authority (TVA) Kingston Fossil Plant in Tennessee resulted in the release of 5.4 million cubic yards of coal ash--also referred to as coal combustion residue (CCR)--into the nearby Emory River. The spill covered more than 300 acres and made 3 homes uninhabitable; it damaged 23 other homes, plus...
Federal Electronics Management: Federal Agencies Could Improve Participation in EPA's Initiatives for Environmentally Preferable Electronic Products
GAO-10-196T: Published: Oct 27, 2009. Publicly Released: Oct 27, 2009.
Advancing technology has led to increasing sales of new electronic devices. With this increase comes the dilemma of managing them at the end of their useful lives. If discarded with common trash, a number of environmental impacts may result, ranging from the loss of valuable resources to the potential release of toxic substances, such as lead. If recycled, they may be exported to countries with wa...
Nuclear Waste: DOE's Environmental Management Initiatives Report Is Incomplete
GAO-09-697R: Published: Jun 2, 2009. Publicly Released: Jun 2, 2009.
The Department of Energy (DOE) spends billions of dollars annually to clean up nuclear waste at sites across the nation that produced nuclear weapons from the 1940s through the end of the Cold War. This waste can threaten public health and the environment. For example, contaminants at DOE's Hanford site in Washington have migrated through the soil into the groundwater, which generally flows toward...

GAO-08-1081: Published: Sep 26, 2008. Publicly Released: Sep 26, 2008.
The Department of Energy (DOE) spends billions of dollars annually to clean up nuclear wastes at sites that produced nuclear weapons. Cleanup projects decontaminate and demolish buildings, remove and dispose of contaminated soil, treat contaminated groundwater, and stabilize and dispose of solid and liquid radioactive wastes. Ten of these projects meet or nearly meet DOE's definition of major: cos...
Electronic Waste: EPA Needs to Better Control Harmful U.S. Exports through Stronger Enforcement and More Comprehensive Regulation
GAO-08-1044: Published: Aug 28, 2008. Publicly Released: Sep 17, 2008.
Increasingly, U.S. consumers are recycling their old electronics to prevent the environmental harm that can come from disposal. Concerns have grown, however, that some U.S. companies are exporting these items to developing countries, where unsafe recycling practices can cause health and environmental problems. Items with cathode-ray tubes (CRT) are particularly harmful because they can contain 4 p...
