Remediation System Evaluation, Hellertown Manufacturing Superfund Site

The Hellertown Manufacturing Superfund Site, located in Hellertown, Pennsylvania 1.5 miles south of Bethlehem, Pennsylvania, is approximately 8.6 acres and addresses trichloroethylene (TCE) contamination of the groundwater resulting from operations of a former spark-plug manufacturing facility. The initial Remedial Investigation found that the primary sources of contamination are onsite lagoons once used for containing process water laden with chemicals including TCE. The Record of Decision required placement of an asphalt cap covering the former lagoon area and a pump-and-treat system to address the groundwater  contamination. Construction of the asphalt cap was completed in 1994 and operation of the pump-and-treat system began in February 1996.
