The Superfund program is administered by the U.S. Environmental Protection Agency (EPA) under the Comprehensive Environmental Response Compensation and Liability Act (CERCLA). The EPA, through Superfund, seeks to clean up sites where toxic and hazardous wastes have been deposited or spilled. Region 6 Environmental Contaminants Specialists provide information, data, and guidance to the EPA to ensure that the cleanups protect migratory birds, and threatened and endangered species.

The information provided by Service contaminants specialists assists the EPA in ensuring that clean ups protect natural resources and the environment, as well as human health, saving money for EPA and the parties responsible for the sites, and ensuring that public resources are protected.
