    Resident request brought ATSDR toVieques

    A resident of Vieques asked ATSDR to find out if activities at the Navy bombing range on the island could affect the health of island residents. ATSDR accepted the request and began gathering information to conduct a public health assessment. ATSDR decided to focus first on evaluating the water that people drink on the island.

    Vieques Water Supply System

    Most residents of Vieques get their drinking water through a pipeline supply system from the mainland of Puerto Rico. Drinking water from this system was tested by the Puerto Rico Department of Health and the U.S. Environmental Protection Agency (EPA). It was also tested by a private environmental company hired by the Navy. ATSDR analyzed the results of all of these tests and concluded that the water from the public water supply system is safe to drink.

    Groundwater wells on Vieques

    ATSDR also evaluated water from groundwater wells in the area. Residents may use water from these wells to supplement their water supply in emergencies when the island's public water supply is temporarily unavailable.

    Water from the primary groundwater wells on the island was tested by EPA and the Puerto Rico Department of Health. Although the water tends to be salty, the water is safe to drink, except for people on sodium-restrictive diets.

    Water from the bombing range cannot reach groundwater wells

    Groundwater that is underneath the bombing range is prevented by gravity, geology and topography from reaching the residential area and the groundwater wells.
