New York

Located in the Northeastern United States, New York is the seventh-most densely populated state in the U.S. The state covers 54,555 square miles and ranks as the 27th largest state by size. The Great Appalachian Valley dominates eastern New York and contains the Lake Champlain Valley as its northern half and the Hudson Valley as its southern half. Much of New York State borders water.

Statewide Assessment of New York’s Karst Aquifers With an Inventory of Closed-Depression and Focused-Recharge Features

Background: The New York State Departments of Environmental Conservation (NYS DEC) and Health (NYS DOH) are concerned about groundwater contamination in the carbonate-bedrock aquifers in New York, especially relating to the unintended introduction of volatile organic compounds (VOCs) and liquid manure to these aquifers. These carbonate rocks form extensive aquifers that transmit, and can yield...

Hydrogeologic Recharge Settings of the Carbonate-Bedrock Aquifers in Livingston and Monroe Counties, Western New York

Background: A sequence of gently dipping carbonate bedrock - the Bertie Formation, Akron Dolostone, and Onondaga Limestone crop out along a 2- to5-mile wide band in western and central New York. These bedrock units trend east-west for 250 miles across the State and form extensive carbonate-bedrock aquifers which transmit and yield water from solution-enlarged fractures, bedding planes, and...

Flood-inundation mapping of Egypt Creek, Dryden, Tompkins County

Problem – Flooding is an annual problem along Egypt Creek in Dryden. Increased runoff from expanding development, sediment clogged channels, and undersized culverts that cannot convey increased flows contribute to the problem. Flood maps for extreme floods are available through the effective FEMA flood insurance study (FEMA, 1978), but these maps, which became effective in 1979, are considered...

Hydrogeology and Water Quality of the North Shore Aquifer in Locust Valley, Town of Oyster Bay, New York

Problem Perchlorate detected in a shallow supply well within the southern portion of the Locust Valley Water District (LVWD) has prompted interest in determining the possible existence of a deeper confined aquifer (North Shore Aquifer) that may be protected from shallow contamination (fig. 1). Previous USGS studies in this area indicate the northern part of Nassau County has a complex...

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...

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). Direct inputs include the more...

Hydrologic Climate Change Indicators

Background Streams and rivers are an important environmental resource and provide water for many human needs. Streamflow is a measure of the volume of water carried by rivers and streams. Changes in streamflow can directly influence the supply of water available for human consumption, irrigation, generating electricity, and other needs. In addition, many plants and animals depend on...

Geohydrology and Water Quality of the Northern and Central Parts of the Tug Hill Glacial Aquifer, Jefferson and Oswego Counties, North Central New York

Problem - The entire Tug Hill glacial aquifer is a 47-mile-long, crescent-shaped mixture of glacial deposits of predominantly sand and gravel on the western side of the Tug Hill Plateau in Jefferson, Oswego, and Oneida Counties in north central New York. The Tug Hill aquifer can be divided into three parts (northern, central, and southern) based on geohydrological setting, depositional history...

Coastal Storm Response Surge, Wave, and Tide Hydrodynamics Network (SWaTH)

Following Hurricane Sandy, the USGS began construction of an overland Surge, Wave, and Tide Hydrodynamics (SWaTH) Network along the Northeastern Atlantic Coast from North Carolina to Maine. This network, developed collaboratively with numerous partners, features the integration of long-term tide gage networks, with real-time rapid-deployment gages (RDG) and mobile storm-tide sensors (STS). An...

Hydrogeology of Two Areas of the Tug Hill Glacial-drift Aquifer, Oswego County, New York

Problem - Several supply wells in Oswego County were evaluated by the USGS in 1999 by using stable oxygen and hydrogen isotopes and chlorofluorocarbon (CFC) age dating techniques. For two municipal well sites (the Villages of Sandy Creek and Lacona, and the Village of Pulaski) that tap a shallow, unconfined aquifer (typically 20-50 ft thick) there were significant discrepancies between ground-...

Hydrogeology of the Virgil Creek Valley in the Town of Dryden, Tompkins County, New York

Problem The Village of Dryden, rural homeowners, farms, and businesses in the Virgil Creek Valley tap several confined sand and gravel aquifers in the Virgil Creek valley in the town of Dryden . The valley contains a large moraine with complex stratigraphy consisting of continuous and discontinuous layers of till, lake deposits, and glaciofluvial sand and gravel. Sand and gravel units form the...

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...
