In 2014, the Superfund Program implemented a new information system, the Superfund Enterprise Management System (SEMS). 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.

The National Priorities List (NPL) is the list of the most hazardous sites across the U.S. and its territories.

This site is cleaned up, is no longer a threat to human health, has been deleted from the NPL, and is known as a Deleted NPL site (see glossary).

Superfund law requires that EPA give communities information about site progress and plans so that they can be actively involved in site cleanup decisions. Learn more about community involvement at this site >>

  Cleanup Impact Summary  
At each site, EPA assesses the risk to humans and the environment and determines the best approach to address the risk. During initial site studies and cleanup, EPA determines if current human exposures to contaminants are under control and takes actions to control any possible human exposures until cleanup has been completed. Once complete, cleanup provides long-term human health and environmental protection at the site.

Current human exposures at this site are under control Current human exposures at this site are under control

see glossary definition for "Human Exposure Environmental Indicator Measure." >>

At each site with known ground water contamination, EPA documents whether ground water contamination is below protective risk-based levels or, if not, whether the migration of contaminated ground water is stabilized.

Contaminated ground water migration is under control Contaminated ground water migration is under control

see glossary definition for "Contaminated Ground Water Migration Environmental Indicator Measure." >>

Contaminants (i.e., hazardous substances, pollutants or contaminants) can be found in several different types of materials on the site including soil and other solid-based media and water or another liquid-based medium (see glossary).

Contaminated Media:  Data not available

EPA classifies contaminants found into groups or types.

  Cleanup Activities At This Site
see glossary definitions for cleanup activities >>

There are many stages of cleanup, including site study, remedy selection, remedy design, remedy construction, and post-construction. Activities undertaken early in the cleanup process focus on understanding problems at the site while those taken later in the cleanup process focus on physically addressing those problems identified.

Many NPL sites are large and complicated. These sites are often broken up into smaller areas to make cleanup easier and more manageable. These areas are called “Operable Units” or OUs (see glossary).

The chart below shows the different types of activities that are underway or complete at each of the cleanup areas (operable units) at the site. Some activities apply to the entire site; EPA assigns these activities to the site-wide operable unit (designated as OU 0).

* At many sites an action, called a “Removal Action” (see glossary), must be taken to eliminate immediate and near-term threats to human health and the environment. Removal actions do not occur at all sites.
  Community Involvement

The goals of the Superfund community involvement (CI) program are to: 1) keep communities affected by sites informed throughout the cleanup process, 2) provide opportunities for communities to comment and offer their input about site cleanup plans, and 3) facilitate the resolution of community issues tied to a site. EPA accomplishes these goals by providing communities different tools and resources to support their site involvement. These resources include independent technical assistance so community members can understand the technical aspects of a site, a public forum for community members to present and discuss their needs and concerns related to the Superfund decision making process, and a job training program to encourage employment of local workers. These are just some of the CI program's resources; to learn more, go to

  Land Reuse

EPA places a high priority on land revitalization as an integral part of its Superfund response program mission, so EPA tries to select cleanup options that encourage and support future use of a site. Sites made ready for use are deemed "Site-wide Ready for Anticipated Use" (see glossary), which means, in part, that all cleanup goals have been achieved for both current and reasonably anticipated future land use.

This site currently does not meet the criteria for Site-wide Ready for Anticipated Use, however parts of the site may be suitable for reuse.

Post-Construction (see glossary) is the stage following completion of the remedy construction. It includes, among other things, activities such as operating the remedy to address the contamination (e.g., ground water pump and treat); implementing, monitoring, and enforcing institutional controls; and a review of the implemented remedies at least every five years to ensure they continue to protect human health and the environment.
Institutional controls (see glossary) such as administrative or legal restrictions may also be components of remedies at a site that remain in place post-construction completion.  view a list of institutional controls at this site >>
Sites or portions of sites may be deleted (see glossary) from the National Priorities List when all cleanup goals have been achieved. This site has been deleted from the National Priorities List
