Portions of the five-acre, industrial Classic Chemical site were developed as early as 1891. Historical operations – including cloth manufacturing and dying; leather dying and tanning; chemical manufacturing; and, most recently, paper sorting and recycling – left a legacy of contamination and regulatory concerns.
Challenge
To achieve regulatory compliance of this complex site under the New Jersey Department of Environmental Protection’s (NJDEP’s) Industrial Site Recovery Act (ISRA) , the owner retained a GZA Licensed Site Remediation Professional (LSRP) to complete the investigations and remedial design necessary to issue a Response Action Outcome (RAO).
Solution
GZA conducted a Preliminary Assessment to identify the presence of AOCs associated with the former and current operations at the property. Of 27 Areas of Concern (AOCs) GZA identified, 24 warranted additional investigation including AST/USTs, transformers, historic spills, and fire suppression foam pump houses. Contaminants of concern include volatile/semi-volatile organic compounds (VOCs/SVOCs), pesticides, polychlorinated biphenyls (PCBs), metals, and per- and polyfluoroalkyl substances (PFAS) The vacant, remote location had been vandalized and used as a dumping ground for tires and unidentified drums in recent years, therefore site clearing was required prior to the Site Investigation. Soil and groundwater sampling and a ground penetrating radar (GPR) survey have been completed; additional investigation will include installation of test pits at site drains and near numerous anomalies that were detected during the GPR survey.
Benefit
GZA’s extensive experience with the investigation and remedial design of brownfield sites in New Jersey enables us to effectively address the lengthy list of complex AOCs on the site, satisfy regulatory requirements, and meet the client’s objectives.
