The map below illustrates the groundwater data-collection network of the USGS New York Water Science Center, Coram Program Office. This network encompasses data collection from approximately 600 groundwater-monitoring wells on Long Island and in the five boroughs of New York City. Data from these stations are collected in varying frequencies to supply our cooperators, stakeholders, and the public with mission critical information.

Discontinued or Threatened Groundwater-Monitoring Wells: List


Purpose

Ground water is the sole source of water supply for more than 3 million people on Long Island, New York. Large-scale ground-water pumpage, installation of sanitary-and storm-sewer systems, and frequent variations in precipitation all have significant effects on regional groundwater levels and streamflow. The U.S. Geological Survey (USGS) has operated and maintained a hydrologic-data-collection program on Long Island and in the five boroughs of New York City since the early 1900’s. This program is needed so that a consistent, long-term, islandwide hydrologic data set is available for scientists to properly manage the region’s water resources.

Groundwater data are the primary focus of the USGS data-collection program on Long Island and in the five boroughs of New York City; however, because most streams, ponds, and lakes in the region are hydraulically connected with the shallow groundwater system, the USGS monitors stream discharge and lake levels as part of its hydrologic-surveillance network. Groundwater-level, lake-level, and stream-discharge data are all needed to accurately assess seasonal fluctuations and long-term trends in groundwater storage and climate change.

Goals

Cooperators

USGS groundwater monitoring on Long Island and in the five boroughs of New York’s City is performed in cooperation with the New York City Department of Environmental Protection, New York State Department of Environmental Conservation, Port Washington Water District, Residents for a More Beautiful Port Washington, Suffolk County Department of Health Services, Suffolk County Water Authority, Town of North Hempstead, Town of Shelter Island, and the U.S. Environmental Protection Agency.
