Problem - Previous hydrologic studies have indicated that there may be sufficient water resources underlying Queens, Kings, Richmond, New York, and Bronx Counties for use as a supplemental water supply in times of drought or other emergency. An extensive ground-water and surface-water monitoring program is necessary to provide a comprehensive hydrologic data set for use in ongoing and future ground-water investigations.

The objective of this project is to provide a continuous hydrologic data set needed for resource assessment, planning, and protection. To meet this objective the U.S. Geological Survey, in cooperation with the New York City Department of Environmental Protection, maintains and operates a network of approximately 225 monitoring wells, 8 streamflow stations, and 10 lakes or ponds within the five boroughs of New York City. Ground- and surface-water levels are monitored at varying frequencies to accurately assess seasonal fluctuations and long-term trends in ground-water and surface-water storage. Water-quality data is collected to monitor nutrient and contaminant loading within the region to determine the condition of the water in the aquifer system and whether it can be used as a source of supplemental supply. All samples are analyzed by the USGS for a broad range of constituents, which include selected nutrients, major ions, trace metals, volatile and semi-volatile organic compounds, and pesticides.

All data collected for the project are published in annual data reports and are available on the internet at http://ny.usgs.gov. The data, collected using standardized instruments procedures, contribute to a nationally consistent data set for assessment of the water quality of the Nation.
