The initial investigation of this site was based on the clients own initiative; however, based on the sale of the property, the site is currently regulated by the New Jersey Department of Environmental Protection (NJDEP) Industrial Site Recovery Act (ISRA).

The client currently retains the site's environmental liability. Past onsite operations included the manufacturing of steel office furnishings and the manufacturing of electric motors for the defense industry. ESI performed a preliminary assessment/site investigation (PA/SI) of the property to identify over 40 Areas of Concern (AOCs).

ESI conducted investigations to delineate both soil and groundwater and investigations to address vapor intrusion at over two dozen residential properties in the surrounding residential neighborhood.

Based on the results of the investigations, over 6,500 tons of onsite-contaminated soil was excavated and disposed of at a client-approved facility. Due to constraints related to maintaining the integrity of the onsite buildings, removal of all soil contamination was not possible. Soil contamination remaining onsite will be Deed Noticed once all other ISRA activities have been completed. In addition, over 2,000 tons of impacted soil was removed from a public park and a residential property adjacent to the site. The impacts at the park and residential property were due to the site's historic operations. The establishment of a Deed Notice was not an option for the Park as dictated by the Township.

Previous operations had also impacted the groundwater beneath the site and a limited area offsite. The results of ESI's groundwater model indicate that two fully penetrating recovery wells and a shallow horizontal recovery well would effectively remove the contamination and prevent further contaminant migration. The treatment system consists of a shallow tray air stripper followed by activated carbon polishing. Treated groundwater is discharged under a NJDEP NJPDES permit. This system has been successful in reducing contaminant concentrations several orders of magnitude. ESI is currently evaluating alternatives to the pump and treat system to complete the groundwater remediation.
