Environmental Contamination: Information on the Funding and Cleanup Status of Defense Sites
GAO-10-547T: Published: Mar 17, 2010. Publicly Released: Mar 17, 2010.
Under the Defense Environmental Restoration Program (DERP), the Department of Defense (DOD) is responsible for cleaning up about 5,400 sites on military bases that have been closed under the Base Realignment and Closure (BRAC) process, as well as 21,500 sites on active bases and over 4,700 formerly used defense sites (FUDS), properties that DOD owned or controlled and transferred to other parties...
Chemical Regulation: Observations on Improving the Toxic Substances Control Act
GAO-10-292T: Published: Dec 2, 2009. Publicly Released: Dec 2, 2009.
The Environmental Protection Agency (EPA) is authorized under the Toxic Substances Control Act (TSCA) to obtain information on the risks of chemicals and to control those that it determines to pose an unreasonable risk. EPA also conducts assessments of chemicals under its Integrated Risk Information System (IRIS) program. Nonetheless, EPA does not have sufficient information to determine whether i...
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...
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...
Electronic Waste: Harmful U.S. Exports Flow Virtually Unrestricted Because of Minimal EPA Enforcement and Narrow Regulation
GAO-08-1166T: Published: Sep 17, 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 damage health and the environment. Items with cathode-ray tubes (CRTs) are particularly harmful because they contain lead, a know...
Perchlorate: EPA Does Not Systematically Track Incidents of Contamination
GAO-07-797T: Published: Apr 25, 2007. Publicly Released: Apr 25, 2007.
Perchlorate has been used for decades by the Department of Defense, the National Aeronautics and Space Administration, and the defense industry in manufacturing, testing, and firing missiles and rockets. Other uses include fireworks, fertilizers, and explosives. Perchlorate is readily dissolved and transported in water and has been found in groundwater, surface water, and soil across the country....
Clean Air Act: EPA Should Improve the Management of Its Air Toxics Program
GAO-06-669: Published: Jun 23, 2006. Publicly Released: Jul 26, 2006.
The Environmental Protection Agency's (EPA) most recent data indicate that 95 percent of all Americans face an increased likelihood of developing cancer as a result of breathing air toxics--pollutants such as benzene and asbestos that may cause cancer or other serious health problems. Sources of air toxics include large industrial facilities, smaller facilities such as dry cleaners, and cars and t...
Hazardous Waste: EPA Needs to Clarify the Types of Mercury Waste That Can Be Treated and Disposed of Using the Debris Regulations
GAO-06-99: Published: Dec 16, 2005. Publicly Released: Jan 17, 2006.
The Environmental Protection Agency (EPA) is responsible for regulating hazardous wastes (such as mercury) under the Resource Conservation and Recovery Act (RCRA). Under RCRA, mercury-containing hazardous waste must meet specific treatment standards before land disposal. But, certain difficult to manage waste due, in part, to its large particle size, can follow alternate "debris" standards that pr...
Electronic Waste: Strengthening the Role of the Federal Government in Encouraging Recycling and Reuse
GAO-06-47: Published: Nov 10, 2005. Publicly Released: Nov 10, 2005.
Advances in technology have led to rapidly increasing sales of new electronic devices. With this increase comes the dilemma of managing these products at the end of their useful lives. Some research suggests that the disposal of used electronics could cause a number of environmental problems. Research also suggests that such problems are often exacerbated by the export of used electronics to count...
Clean Air Act: Emerging Mercury Control Technologies Have Shown Promising Results, but Data on Long-Term Performance Are Limited
GAO-05-612: Published: May 31, 2005. Publicly Released: Jun 23, 2005.
In March 2005, the Environmental Protection Agency (EPA) issued a rule that will limit emissions of mercury--a toxic element that causes neurological problems--from coal-fired power plants, the nation's largest industrial source of mercury emissions. Under the rule, mercury emissions are to be reduced from a baseline of 48 tons per year to 38 tons in 2010 and to 15 tons in 2018. In the rule, EPA s...
