Water Quality

Different uses of water may require a different level of “quality” of water; for example, water that contains dirt and grime might work fine for agricultural uses, but industrial uses and drinking water require a different level of water quality; or water that might be safe to use in industrial and agricultural uses may not be safe to drink or promote healthy ecosystems. The NYWSC collects water-quality data for all water resources and works with the public, government agencies, organizations, and the private sector to identify and understand environmental issues and concerns regarding the quality of water supplies in the Nation and abroad. Water-quality data are then used to determine the health of various ecosystems, including wetlands, urban landscapes, coastal environments, and watersheds. Effects of nutrient and micropollutant loading to watersheds and wetlands, habitat response to changes in infrastructure, wetlands restoration for the effects of treating urban wastewater, and toxicity in waters affected by urban runoff are some of the more recent projects undertaken by the NYWSC with State and local cooperators.

New York Nowcast, Recreational Beaches of New York

Problem – Currently, swim advisories or closings are issued by beach managers based on standards for concentrations of bacterial indicators such as Escherichia coli (E. coli). Standard culture methods for these bacteria take at least 18-24 hours before results are available. At most Great Lakes beaches, the beach is posted with an advisory or closing or is determined to be acceptable for swimm

Urban Waters Initiative – BRONX & HARLEM RIVERS

Problem Over the past century, the Harlem River watershed has become highly urbanized with 90 percent of the waterway constrained by infrastructure, which has limited access for recreational use. Bound by New York (Manhattan) and Bronx Counties, the Harlem River is a tidal strait between urbanized estuaries to the north (Hudson River) and south (East River).

Development of a Ground-Water Flow Model for the Manhasset Neck Peninsula, Nassau County, New York

Problem The ground-water flow system underlying the Manhasset Neck Peninsula, which provides potable water to the local population, consists of a complex assemblage of Pleistocene- and Cretaceous-age sediments that form five aquifers and at least two confining units. Recent hydrogeologic mapping in Manhasset Neck indicates significant glacial erosion of the Magothy aquifer, Raritan Clay, and Llo
