Hudson River Watershed Database and Mapping Project Software & Data
ARD is developing the Hudson River Watershed Project, which includes the entire Hudson River Superfund site, over 200 river miles from the mouth of the river in New York Harbor to beyond Hudson Falls. Fish and sediments throughout the Hudson River are contaminated with polychlorinated biphenyls (PCBs), forcing commercial and recreational fishing closures and advisories throughout the river.
The project integrates sediment chemistry and tissue chemistry data from:
- EPA's Superfund Reassessment Remedial Investigation;
- The State of New York's long-term monitoring of PCB and other contaminant concentrations in fish throughout the river;
- General Electric's investigations of sediment and fish;
- NOAA's studies of PCB levels in fish; and
- The U.S. Department of the Interior's studies of PCB concentrations in treeswallow nestlings, eggs and prey organisms.
The Hudson River Watershed Project's objective is to provide state and federal trustees with the ability to integrate the large amount of existing point data on sediment chemistry, tissue chemistry, and sediment toxicity with maps that identify key habitats, potential restoration sites, and potential point sources (including stormwater). Maps showing the distribution of Brownfield sites, land uses, contaminant distributions, wetlands, and other information can help focus cooperative restoration planning and improve decision-making processes.
