Congress passed the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) in 1980. The word Superfund comes from a provision in the original CERCLA that raised funds for cleanups through imposition of a tax on certain petroleum and chemical companies. CERCLA gives EPA the authority to investigate and address threats posed by abandoned hazardous waste sites. It also gives EPA the authority to identify parties responsible for the contamination and compel them to pay costs associated with cleanups and risk reduction. As part of the Superfund process, investigators collect samples of soil and groundwater at, and usually in the vicinity of, sites under evaluation, looking for hazardous chemicals. Of particular interest are chemicals that have or may reach receptors (e.g., drinking water wells or residential yards). Information about site-related chemicals and receptors goes into a complex formula, called the hazard ranking system (HRS), that generates a score for each site. Sites with scores of 28.5 or higher may go on the National Priority List (NPL). However, there are many Superfund sites that are not on the NPL. Some proceed under the Superfund Alternative Approach. Others proceed under state supervision, or achieve cleanup through an emergency action that results in immediate removal of contamination. The ultimate goal of all of the processes is to implement a remedy that adequately addresses risks associated with the chemical release at a site. EPA removes sites that have adequately addressed risk from the NPL, a process called delisting. The adjacent links connect to pages with alphabetical lists of Superfund sites in each state; those lists in turn contain links to EPA information on the sites. Sometimes I've summarized additional information about the location of sites, relevant chemicals, and other details. EPA moves their web pages regularly, and I sometimes have trouble keeping up. If you find dead links, please let me know. Thanks! |
