Background

The Superfund program, a federal program established by Congress in 1980, investigates and cleans up the most complex, uncontrolled, or abandoned hazardous waste sites in the country and endeavors to facilitate activities to return them to productive use. There are many phases of the Superfund cleanup process, including considering future use and redevelopment at sites and conducting post cleanup monitoring of sites.

Throughout the process of designing and constructing a cleanup at a hazardous waste site, EPA's primary goal is to protect human health and the environment, the agency's core mission. EPA is required by statute to review the sites every five years after the cleanup is in place. It is important for EPA to regularly check to ensure the cleanup is working properly. These reviews confirm that the remedies put in place continue to be effective or identify any issues (that may affect the protectiveness of the cleanup and, if necessary, recommend action(s) to address them.
