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 current estimate for refreshing the content on this page is April 2015.
Superfund Site Progress Profile
FORMER NANSEMOND ORDNANCE DEPOT
(EPA ID: VAD123933426)
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.
EPA is working to determine whether there are human exposures to contaminants
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.
There is insufficient data to determine migration control status"
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).
The contaminants listed via the links below are considered the contaminants of concern
(see glossary) to be addressed by
cleanup actions at the site.
Contaminated Media: Soil
EPA classifies contaminants found into groups or types
(listed below). To view all contaminants of concern at the
site click on the "view contaminants of concern at this site" link.
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
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.
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
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.
Sites or portions of sites may be deleted (see glossary) from the
National Priorities List when all cleanup goals have been achieved.
A portion of this site has been deleted from the National Priorities List
