How are Superfund sites cleaned up?

There is no one way to clean up a hazardous waste site. The Superfund program uses a wide range of technologies and resources to implement an effective cleanup.

Over the years, EPA has gained a great deal of experience and knowledge about the best ways to clean up all kinds of toxic chemicals and contaminated areas. One of the things EPA has learned is that certain kinds of sites - such as landfills, solvent-contaminated sites, wood treatment facilities, and others - show similar patterns of contamination and can, therefore, be cleaned up using similar resources and technologies. These cleanup solutions are called presumptive remedies and are used to make hazardous waste site cleanups more efficient and effective.

To obtain information on how a specific Superfund site was cleaned up, contact the EPA regional office that is responsible for the site, or review site information available from EPA's Superfund Site Information tool.  If the site is on the National Priorities List (NPL), EPA established a site repository in the local community (generally at the library or city hall). To locate the site repository, contact the EPA Community Involvement Coordinator.
