In 2014, the Superfund Program implemented a new information system, the Superfund Enterprise Management System (SEMS). As part of this transition, many Superfund documents are being made available at Superfund's online document repository. 

Further efforts to migrate data to SEMS and to enhance data quality control are now in the final stages. The Program will continue to rely on the final CERCLIS data set (dated November 12, 2013, which reflects official end of Fiscal Year 2013 Program progress) for public reporting until a complete and accurate SEMS data set is available.

  • About the data and reports page

    The reports and products offered here contain information on the assessment and remediation of current and archived hazardous waste sites.

    The CERCLIS Public Access Database contains a selected set of “non-enforcement confidential” information. The data describes what has happened at Superfund sites. This database includes lists of involved parties (other Federal Agencies, states, and tribes), Human Exposure and Ground Water Migration, and Site Wide Ready for Reuse, Construction Completion, and Final Assessment Decision (GPRA-like measures) for fund lead sites. Other information that is included has been included only as a service to allow public evaluations utilizing this data.

CERCLIS Reports and Data Files

CERCLIS is a database of potential and confirmed hazardous waste sites at which the EPA Superfund program has some involvement. It contains sites that are either proposed to be or are on the National Priorities List (NPL) as well as sites that are in the screening and assessment phase for possible inclusion on the NPL.

  • CERCLIS sites with Potential Smelter Activity:
    • Description

      This report includes sites that have smelting-related, or potentially smelting-related, indicators in the CERCLIS database. The report includes information on the site location as well as contaminants of concern.

  • List 9 - Active CERCLIS Sites:
    • Description

      The List 9 displays the sequence of activities undertaken at active CERCLIS sites. An active site is one at which site assessment, removal, remedial, enforcement, cost recovery, or oversight activities are being planned or conducted. For many sites, the report also includes a narrative description of the site's history, location and geology, nearby populations, current and former land use, and suspected contaminants.

Archived Sites Reports and Data Files

The Archive designation means that, to the best of EPA's knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list this site on the National Priorities List (NPL). This decision does not necessarily mean that there is no hazard associated with a given site; it only means that, based upon available information, the location is not judged to be a potential NPL site.

  • List 8 - Archived Sites:
    • Description

Frequently asked questions:

What type of information is contained in the CERCLIS database?

The Comprehensive Environmental Response, Compensation and Liability Information System is sponsored by EPA’s Office of Superfund Remediation Technology Innovation, Information Management Center. The database contains information on site inspections, preliminary assessments and remediation activities at hazardous waste sites.

What does Archive mean and how can I find information on Archived sites?

Archived sites have been removed and archived from the CERCLIS inventory. This designation means that to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list this site on the National Priorities List (NPL), unless information indicates that this decision was not appropriate or other considerations require a recommendation for listing at a later time. This decision does not necessarily mean that there is no hazard associated with a given site; it only means that based upon available information, the location is not judged to be a potential NPL site.

A listing of those sites which have been removed and archived from the inventory of Superfund sites can be obtained by ordering a List 8T report.

Find site documents

By visiting Superfund's

How can I find actual documents for a site, such as permits and notices?

Visit the Superfund online document repository for Administrative Records and other documents collections. Freedom of Information Act (FOIA) requests can also be made here.

Top of Page

How can I find the type, level, treatment technologies and cleanup levels of contaminants found at a particular site?

The type, level, treatment technologies and cleanup levels of contaminants found at a particular site can be obtained by requesting a RODS report. Site information such as name and EPA ID or search criteria such as city, state and key words may be listed. A generated report will contain the abstract field and the remedy field. The abstract field describes the site and the primary contaminants. The remedy field describes the treatment technologies and chosen remediation method. A full-text ROD can also be requested, which contains the established cleanup levels for contaminants found at a site.
