Superfund Site Profile
The Frontera Creek site is located in Humacao on the eastern coast of Puerto Rico. It includes Frontera Creek from east of Junquito Ward to its entry into the Caribbean Sea, 13 industrial properties next to the creek, the three Santa Teresa Lagoons and associated abandoned pump stations, and the Ciudad Cristiana housing development. Industrial properties nearby discharged wastes directly into Frontera Creek, contaminating soil and water with hazardous chemicals. To clean up the site, EPA removed contaminated soils and sediments from several areas. The cleanup finished in 1995. Under current conditions at the site, potential or actual human exposures are under control. EPA took the site off the Superfund program’s National Priorities List in December 1998.
