Total Maximum Daily Load Reports for the New York Harbor


Total Maximum Daily Loads (TMDLs) are developed by each state for all waters identified on their Section 303(d) list of impaired waters. TMDLs determine the maximum pollutant load allowed to enter an impaired waterbody while still continuing to meet water quality standards. They are an important tool for improving water quality as they serve as a link between water quality standards and the implementation of control actions to achieve those standards. Past efforts of the Water Quality Work Group focused on using mathematical models to estimate load reductions necessary to meet water quality standards and led to the production of several TMDL reports focused on nutrients, pathogens, dissolved oxygen, and toxic contamination, including trace metals for the New York Harbor.
