The National Priorities List (NPL) is the list of the most hazardous sites, also known as Superfund 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.

The Problem: Contamination & Exposure
|
|
| |
| |
| |
|
Contamination
|
| |
|
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. The contaminants
listed via the links below are considered the contaminants of concern to be addressed by
cleanup actions at the site. (see glossary)
|
Contaminated Media: Debris
|
|
EPA classifies contaminants found into groups or types (listed below). To view all contaminants of concern at the
site click on the view detailed list link.
|
Types of Contaminants: Base Neutral Acids, PCBs, Pesticides, VOC

|
Exposure
|
| |
|
At each site, EPA determines the possibility for human and ecological contact (i.e., exposure) with contaminants at the site. If the possibility for exposure to contamination exists, EPA conducts a study known as a risk assessment. During the risk assessment, EPA determines if the site poses a risk to humans, and if so, identifies actions that can be taken to control any possible exposure to humans until site cleanup has been completed. Once complete, cleanup provides long-term human health and environmental protection at the site.
|
|
Under current conditions at this site, potential or actual human exposures are under control.

The Solution: Cleanup Process & Progress

|
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
|
Superfund community involvement is the process of getting community members actively involved in the cleanup of a Superfund site.
Throughout a site cleanup, the Superfund law requires the EPA to give communities information about site progress and plans so that they can be actively involved in site cleanup decisions.
To find out more about community involvement activities at this Superfund site and how you can become involved in site cleanup/reuse decisions, please contact:
Angeles Herrera .

|
Post-Construction
|
|
Post-Construction (see glossary) is the stage following completion of the majority of physical cleanup. The goal of Post-Construction is to ensure that the cleanup provides for the long-term protection of human health and the environment.
