Superfund Site: NORTH PENN - AREA 12

Superfund Site Profile


The North Penn Area 12 site includes the former Transicoil facility and the adjacent former control facility for a Nike Missile Base on Trooper Road in Worcester Township, Montgomery County, Pennsylvania. Between 1952 and 1991, several different owners  manufactured electric motors at the 25-acre former Transicoil facility. State records show that the facility used several drums of trichloroethylene (TCE) each year as a degreasing solvent until 1976, when it switched to trichloroethane. The company stored waste oil and solvents in an underground tank, and allegedly disposed of spent solvents in the septic system and directly on the ground. In 1979, the State found elevated concentrations of solvent-based chemicals in on-site wells and in private off-site wells. Subsequent sampling by a consultant to Transicoil confirmed the results.

The North Penn Area 12 Site also includes the 12-acre former Nike missile control facility that was located adjacent to the Transicoil property and operated by the U.S. Army. The former Nike control facility property was used by the Army from 1954 to 1968. TCE was allegedly used and disposed of at the former Nike control facility property between 1954 and 1968.
