EPA added the Waldick Aerospace Devices, Inc. site in Wall Township, New Jersey to the Superfund National Priorities List on June 1, 1986 because hazardous chemicals were found in the soil and ground water.  The one and a half acre superfund site located in Monmouth County contained a former industrial facility.  The property was used for manufacturing and plating metal parts for the aerospace industry.  In 1982, Monmouth County and State inspectors found that wastewater and used machine oil was being discharged directly onto the ground.  Samples revealed that the wastes contained heavy metals, acids, and volatile organic compounds (VOCs), which are potentially harmful contaminants that can easily evaporate into the air.  On-site soil, ground water and two buildings were contaminated.  Approximately 41,000 people live within a three-mile radius of the site.

In 1983, in an immediate response, the state and county excavated about 80 cubic feet of contaminated soil.  In 1985, after the facility was abandoned, EPA discovered about 30 containers filled with hazardous materials and a cabinet filled with laboratory chemicals.  The hazardous materials were securely shipped to a hazardous waste disposal facility.

In 1986, EPA initiated an investigation into the nature and extent of the site contamination in order to evaluate cleanup options.  In the first phase of the cleanup, EPA decided to address contaminated soils and buildings.  On-site buildings were demolished and approximately 3,500 cubic yards of contaminated soils were excavated, treated and removed from the site.  In 1991, EPA modified its plan to address the ground water contamination.  EPA found that ground water samples showed substantially reduced contaminant concentrations.  As a result, EPA began a long term monitoring program in 1997 to help determine whether implementing the ground water cleanup plan was still necessary or appropriate.  Based on the information gathered to date, it appears that the concentration of contaminants in the ground water is decreasing and EPA will continue to monitor its progress.
