Superfund: Greater EPA Enforcement and Reporting Are Needed to Enhance Cleanup at DOD Sites
GAO-09-278: Published: Mar 13, 2009. Publicly Released: Apr 16, 2009.
Prior to the 1980s and the passage of environmental legislation--particularly the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) governing environmental cleanup--Department of Defense (DOD) activities contaminated millions of acres of soil and water on and near DOD sites.

Hurricane Katrina: EPA's Current and Future Environmental Protection Efforts Could Be Enhanced by Addressing Issues and Challenges Faced on the Gulf Coast
GAO-07-651: Published: Jun 25, 2007. Publicly Released: Jun 25, 2007.
In 2005, Hurricane Katrina's impact on the Gulf Coast included damage to the environment from chemical and hazardous materials releases. Also, the widespread demolition and renovation activities still under way in New Orleans may release asbestos fibers into the air, posing a potential additional health risk. This report, conducted at the Comptroller General's initiative, addresses (1) the Environ...
Leaking Underground Storage Tanks: EPA Should Take Steps to Better Ensure the Effective Use of Public Funding for Cleanups
GAO-07-152: Published: Feb 8, 2007. Publicly Released: Feb 22, 2007.
Underground storage tanks that leak hazardous substances can contaminate nearby groundwater and soil.

In many cases, liable parties meet their cleanup responsibilities. Ho...
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...
