Superfund Site: JUNCOS LANDFILL
Superfund Site Profile
The Juncos Landfill is located in Juncos, Puerto Rico. The 11-acre area is a closed municipal landfill.
Municipal wastes, including mercury thermometers, were disposed of at the site from 1957 to 1977. The landfill closed in 1981. Landfill operations contaminated the soil, off-site leachate and air with mercury and volatile organic compounds (VOCs), which are potentially harmful contaminants that easily evaporate in the air. Following immediate actions to protect human health and the environment, EPA put the site’s long-term remedy in place. Under current conditions, potential or actual human exposures are under control. Long-term groundwater monitoring is ongoing.
