Near real-time environmental data are being generated and publicly posted posted by HRECOS (Hudson River Environmental Conditions Observing System), HRNERRS (Hudson River National Estuarine Research Reserve System), and the USGS (U.S. Geological Survey). The River Keeper measures and reports on bacteria in the Estuary. New York City's Harbor Water Quality Survey has been measuring dissolved oxygen, temperature, and bacteria in the Harbor since 1909.

The Contaminant Assessment and Reduction Project (CARP) collected data on toxic chemicals (PCBs, pesticides, dioxins/furans, PAHs, mercury, and cadmium) in Hudson Estuary water, sediment and biota between 1998 and 2001. These data were used to make predictions for how contaminant concentrations change after user-specified load reductions.
