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.
