Superfund

The law commonly known as the Superfund (SF) law was established in 1980 by an act of Congress in response to concerns about the impact of contaminated property on human health and the environment. Superfund gives the U.S. Environmental Protection Agency (EPA) authority and funds to help clean up polluted sites.

A Superfund site is a property known to be contaminated by hazardous waste that may pose unacceptable risks to human health and the environment. The contamination is often the result of mismanagement including dumping onto the ground or into a waterway or improper storage of waste.

The threat at a Superfund site requires action to address the contamination and the Superfund trust fund can be used to pay for most of the cleanup process, if a responsible party is not available to pay for the cleanup. The first step in the process is a site assessment to learn more about the site and to determine if the contamination is significant enough to list the site on the EPA’s National Priority List (NPL). Once listed on the NPL, the contamination is investigated and studies are done to determine what remedial steps are required to clean up the site. In certain situations where contamination poses an imminent threat to the public and/or the environment, the EPA can address those threats via emergency removals. The agency coordinates these removals with the Remediation and Redevelopment Program and with local officials.

Across the United States, thousands of hazardous waste sites are identified as a Superfund site and are listed on the National Priorities List (NPL), which prioritizes the site for cleanup using Superfund. In Wisconsin, the state is responsible for the management of some Superfund sites. See below for more information about Superfund sites located in Wisconsin. Additional information is available by searching the Remediation and Redevelopment Database (BRRTS); select the Superfund NPL option under Additional Site Characteristics.
