The Martin Aaron, Inc. site operated as a steel drum recycling facility for thirty years, from 1968 to 1998, though industrial companies have made use of the site since the late 19th century, contaminating soil and groundwater in the surrounding area. The drums at the facility, containing residue of hazardous chemicals, were not correctly handled or disposed of, releasing substances such as arsenic and polychlorinated biphenyl into the groundwater and soil. Waste such as abandoned equipment and empty steel drums was removed from the site by the EPA and NJDEP, the latter of which initially tested the site for contamination in 1987. Like the Welsbach/General Gas Mantle site, the Martin Aaron, Inc. site was placed on the National Priorities list in 1999.
