• Establish the magnitudes and relative importance of specific contaminant transfers within<br />
the <strong>Newark</strong> <strong>Bay</strong> study area, including:<br />
− Import and export of COPCs and COPECs between <strong>Newark</strong> <strong>Bay</strong> and the <strong>Passaic</strong><br />
and Hackensack rivers, to the North,<br />
− Loads from tributaries and other point and nonpoint sources adjacent to the <strong>Bay</strong>,<br />
− Re-mobilization of deposited contaminants or removal from the water column by<br />
settling of particle-bound COPCs and COPECs within the <strong>Bay</strong> itself,<br />
− Import and export of COPCs and COPECs between <strong>Newark</strong> <strong>Bay</strong> and other<br />
hydraulically connected waterways at the Southern end of <strong>Newark</strong> <strong>Bay</strong> (i.e., the<br />
Arthur Kill and Kill van Kull).<br />
• Provide management guidance for the adverse ecological and human health effects of the<br />
transport and ultimate fate of COPCs and COPECs within the system.<br />
• Assess the effectiveness of alternative remedial actions that may be implemented in <strong>Newark</strong><br />
<strong>Bay</strong> proper, in the 17-mile tidal reach of the <strong>Passaic</strong> <strong>River</strong> and elsewhere in the model<br />
domain, during both the remediation and post-remediation periods.<br />
• Assess sediment quality and contaminant levels that will result from a reduction or<br />
elimination of sources of COPCs and COPECs to the system, as well as the time frame for<br />
improvement under various remedial action alternatives.<br />
The modeling portion of the <strong>Newark</strong> <strong>Bay</strong> study area will overlap with that used for the<br />
Lower <strong>Passaic</strong> <strong>River</strong> Restoration Project and will consider the <strong>Passaic</strong> <strong>River</strong>, as well as the<br />
Hackensack <strong>River</strong>, <strong>Newark</strong> <strong>Bay</strong> and other tributaries. This <strong>Passaic</strong> <strong>River</strong> - <strong>Newark</strong> <strong>Bay</strong> model will<br />
also consider the interaction of this system with the contiguous waters of the Kill van Kull, the<br />
Arthur Kill, the Hudson <strong>River</strong> and greater NYNJ Harbor system. It is necessary to do so to ensure<br />
that the far-field boundary conditions do not artificially influence the transport and distribution of<br />
COPCs and COPECs within the <strong>Newark</strong> <strong>Bay</strong> model domain. Additionally, material that is<br />
transported out of the <strong>Newark</strong> <strong>Bay</strong>, should a major storm event occur in the future, could<br />
potentially have an adverse impact on more distant regions, and it will therefore be necessary to have<br />
the capability to quantify the potential significance of such impacts should a major storm event<br />
occur at various points in time.<br />
Although the preceding macro-scale transport processes will be explicitly considered in the<br />
context of the <strong>Passaic</strong> <strong>River</strong> – <strong>Newark</strong> <strong>Bay</strong> model investigations, there remain additional areas within<br />
<strong>Newark</strong> <strong>Bay</strong> where it may be desirable to represent the system with a still higher level of detail.<br />
Hence, it is envisioned that the model grid representing <strong>Newark</strong> <strong>Bay</strong> will incorporate a finer level of<br />
resolution in some localized areas, beyond what would have been required for a model of the overall<br />
system that focused on the lower <strong>Passaic</strong> <strong>River</strong> alone. Currently the plan for the <strong>Newark</strong> <strong>Bay</strong> <strong>Study</strong><br />
Area is to develop a single integrated model for both water bodies. This approach is preferable with<br />
respect to ease of use and performing management remediation scenarios.<br />
