What Are the Risks at the Site?

There is insufficient information to determine the site-wide human exposure status at the Atlantic Fleet Weapons Training Area - Vieques Superfund Site. The Atlantic Fleet Weapons Training Area - Vieques, includes certain areas of the island of Vieques and nearby waters that have become contaminated primarily by United States Department of Defense activities. From the 1940s until 2003, the US Navy administered lands on both the western and eastern ends of Vieques Island. The lands were used for military training and operations (ship-to-shore gun fire, air-to-ground bombing by naval aircraft, Marine amphibious landing, or combinations), and to store munitions for Atlantic Fleet training. Extensive amounts of unexploded ordnance and remnants of exploded ordnance have been identified in the range areas of Vieques, and in the surrounding waters. The Navy is currently conducting a removal of all surface munitions items in the impact area in east Vieques. This action needs to be completed before a comprehensive study to evaluate the nature and extent of the contamination can be performed. Currently, hazardous substances that may be present at the site have not been fully characterized, but may include mercury, lead, copper, magnesium, lithium, perchlorate, TNT, napalm, depleted uranium, PCBs, solvents, and pesticides. As soon as the time critical removal action of unexploded ordnance is complete, the Navy will conduct an RI/FS to define the nature and extent of the contamination.

The Navy and EPA ensure community participation throughout the remedial process by meeting with residents and affected stakeholders, issuing public notices and updating fact sheets. A site profile has been established on the EPA website to keep the community informed of recent progress at the site. Additionally, an EPA Community Involvement Coordinator is assigned to the site and can address specific community concerns as they arise.  A Community Involvement Plan was updated in 2015.  The U.S. Navy worked jointly with the Environmental Protection Agency, the U.S. Fish and Wildlife Service, the Puerto Rico Environmental Quality Board, and the Puerto Rico Department of Natural and Environmental Resources to develop a Community Involvement Plan update. The Community Involvement Plan is designed to facilitate two-way communication between the community and the agencies involved in the cleanup of former Navy lands on Vieques, Puerto Rico. It was developed in accordance with the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), commonly known as the Superfund program. The Community Involvement Plan was developed with input and review by the public and other stakeholders in the cleanup process. As such, it provides a history of the former Naval facilities; discusses the local community, including its background, makeup, and specific concerns; and provides the structure of the community involvement program. Community input on the Community Involvement Plan was provided through interviews, a survey of Vieques residents and business owners, and community feedback at agency-

Status at this
Superfund Site
What does this mean?
Human Exposure Under Control No Yes means assessments indicate that across the entire site:
  1. There are currently no unacceptable human exposure pathways; and
  2. EPA has determined the site is under control for human exposure.

No means an unsafe level of contamination has been detected at the site and a reasonable expectation exists that people could be exposed.

Insufficient data means that, due to uncertainty regarding exposures, one cannot draw conclusions as to whether human exposures are controlled, typically because:
  1. Response to the contamination has not begun; or
  2. The response has begun, but it has not yet generated information sufficiently reliable to evaluate whether there are currently any unacceptable human exposure pathways at the site.
Groundwater Migration Under Control Insufficient Data

Yes means EPA reviewed all information on known and reasonably expected groundwater contamination. EPA concluded the migration of contaminated groundwater is stabilized and there is no unacceptable discharge to surface water. EPA will conduct monitoring to confirm that affected groundwater remains in the original area of contamination.

No means EPA has reviewed all information on known and reasonably expected groundwater contamination, and the migration of contaminated groundwater is not stabilized.

Insufficient data means that due to uncertainty regarding contaminated groundwater migration, EPA cannot draw conclusions as to whether the migration of contaminated groundwater is stabilized.

Construction Complete No

Yes means the physical construction of the cleanup is complete for the entire site.

No means either physical construction is not complete or actions are still needed to address contamination.

Sitewide Ready for Anticipated Use No Yes means:
  1. All cleanup goals affecting current and reasonably anticipated future land uses of the entire site have been achieved, so there are no unacceptable risks;
  2. All required land-use restrictions or other controls have been put in place; and
  3. The site has achieved Construction Complete status.

No means that one or more of these three criteria have not been met. However, a site listed as no may still have redevelopment occurring on portions of the site and may be eligible for additional redevelopment.
