Understanding this Superfund site

Corozal Well is a federal Superfund site in Puerto Rico. The Superfund program, created by Congress in 1980, addresses sites where hazardous substances have been released or threaten release into the environment. EPA scores potential sites using the Hazard Ranking System; those that score high enough are placed on the National Priorities List.

Current status: Deleted from NPL. This site is on EPA's National Priorities List, which identifies the most serious uncontrolled or abandoned hazardous waste sites in the country. Listing triggers federal cleanup authority and funding under CERCLA (the Superfund law).

Contaminants of concern include tetrachloroethene, trichloroethene. Contamination has been detected in groundwater.

If you live near this site and have health concerns, your state health department can provide site-specific guidance. EPA maintains a community involvement program for most NPL sites, and site documents — including the Record of Decision, five-year reviews, and public health assessments — are typically available through EPA's Superfund site profile.
