Contaminants in the Passaic River include PAHs, PCDD/F, PCBs, DDT, and other pesticides and their by-products as well as heavy metals like Hg, Cr, and Pb. Researchers investigated the development of an in situ remediation technology using nanoscale ozone bubbles and ultrasound to decontaminate river sediments. Preliminary experimental results showed reasonable PAH removal efficiencies from contaminated sediments. The data obtained from the lab experiments will be used to develop a pilot-scale study for possible field application. https://www.issmge.org/uploads/publications/1/45/06-technical-committee-21-tc215-18.pdf
