Risk Assessment for the Passaic River Study Area in New Jersey

Passaic River Study Area in New Jersey

Cardno ChemRisk developed an overall science-based strategy that involved human health risk assessments, NRDA, and remediation issues related to contaminated sediments in the lower six miles of the Passaic River.

When the project began, the client was the sole potentially responsible party for the lower six miles of the Passaic River Study Area Superfund Site and needed assistance with human health risk assessment issues under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and the Natural Resource Damage Assessment (NRDA) as well as help identifying other potentially responsible parties.

Staff performed the review and critique of the Environmental Protection Agency risk assessment, preparation of a screening level human health and ecological risk assessment, development of a focused sediment and biota sampling plan, use of environmental fingerprinting to identify other sources of polychlorinated dioxins/furans, evaluation of microbrial risks from combined sewer outfalls, and design and implementation of a creel angler survey to determine site-specific fish consumption rates.  

Much of this work was published in peer-reviewed scientific literature.
