Kearny Marsh

The New Jersey Meadowlands Commissions (NJMC) has determined that remediation and restoration of the Kearny Marsh ecosystem is a high priority. Successful remediation of this site will involve collection and treatment of highly contaminated leachate that enters the marsh from the uncapped Keegan landfill and remediation of highly contaminated sediments.

Restoration of the Kearny Marsh ecosystem may also be impacted by the presence of combined sewer overflows (CSOs) that empty directly into Kearny Marsh water sources. These system inputs contribute nutrients (nitrogen and phosphorus) as well as toxic contaminants, such as PCBs, PAHs, and halogenated organic compounds to the marsh.

The ultimate project goal is to provide solutions for remediation of the Kearny Marsh ecosystem. The approach is to develop engineered methods to interdict and treat on-going discharges to the Kearny Marsh ecosystem and to evaluate technological options to remediate the contaminated leachate and sediments. To successfully accomplish this complex remediation and restoration an interdisciplinary approach is required.
