Regulatory Agency: New Jersey Department of Environmental Protection (NJDEP) – Industrial Site Remediation Act (ISRA)
Contaminants: Volatile Organics (Groundwater ) Metals, Volatile Organics, Polycyclic Aromatic Hydrocarbon and Petroleum Hydrocarbons (Soil)
Remediation: Pump and Treat (Total Fluids) and Soil Excavation
Treatment: Air Stripping, Activated Carbon, and Offsite Disposal
Scope: Investigate, Investigate, Remediate, Design, Build and Operate
- ESI conducted a Preliminary Assessment / Site Investigation (PA/SI) at the facility and identified over 40 Areas of Concern (AOCs).
- Investigations identified contaminants in soil and groundwater requiring remediation.
- Soil remediation consisted of excavation and off-site disposal. Groundwater remediation has consisted of pump-and-treat.
- Property is currently being redeveloped and returned to productive use.
Photo: The contamination extended beneath a residential neighborhood and a municipal playground. To ensure public satisfaction and allay fears, ESI actively participated in meetings with the client and citizens of the surrounding community.
Cessation of operations and the sale of the property triggered ISRA.

Past onsite operations included the manufacturing of steel office furnishings and the manufacturing of electric motors for the defense industry. ESI performed a PA/SI of the property to identify over 40 AOCs.
ESI conducted investigations to delineate both soil and groundwater and investigations to address potential vapor intrusion at over two dozen residential properties in the surrounding residential neighborhood.
Based on the results of the investigations, over 8,500 tons of onsite and offsite-contaminated soil was excavated and disposed of at a client-approved facility. Previous operations had also impacted the groundwater beneath the site and a limited area offsite.
Remediation of the groundwater consisted of a “pump and treat” system that established control of the plume and reduced the contaminant concentrations by several orders of magnitude.
While the client initially retained the site’s environmental liability, the property was targeted for revitalization by the local redevelopment committee. A developer was chosen, and the environmental liability transferred to the developer. The property is presently being redeveloped for a mixed residential/commercial use.
