EPA Superfund Program: NAVAL SECURITY GROUP ACTIVITY, SABANA SECA, PR

Superfund Site Profile

The Naval Security Group Activity site is located next to Sabana Seca in Puerto Rico, about 11 miles west of San Juan. The 2,200-acre facility is a naval communications station that operates a high-frequency direction finding facility. The site is divided into North and South Tracts. From the early 1950s through 1970, the operation's Public Works Department deposited all waste from the station at various areas on the South Tract. Communications facilities were, and still are, located on the North Tract. Waste materials included paints, solvents, waste oil and battery acid. A pest control shop also operated on the South Tract from the 1950s through 1979. Workers spilled various pesticides around the shop building. They also mixed pesticides and cleaned applicators in a sink outside the shop that discharged directly to the ground. Facility operations contaminated soil and groundwater with hazardous chemicals. After cleanup, EPA took the site off the Superfund program’s National Priorities List in October 1998.
