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.

Stony Clove Basin Sediment and Turbidity Monitoring

Problem Suspended-sediment concentration (SSC) and turbidity are primary water-quality concerns in New York City’s (NYC) water-supply system (U.S. Environmental Protection Agency, 2007). In the NYC water-supply system turbidity is largely caused by clay and silt rather than organic material (Effler et al. 1998, Peng et al. 2002, 2004). Sediment can originate from the watershed land surface and...

Esopus Sub Basin Sediment and Turbidity Monitoring

Problem The Esopus Creek is located in the Catskill Mountains of New York State and is part of New York City’s water supply system. In 1915 damming of a portion of the creek formed the Ashokan Reservoir splitting the creek into upper (upstream of the reservoir) and lower (downstream of the reservoir) segments. The Ashokan Reservoir watershed is 255 mi2 and is one of two reservoirs in the New...

Acidification and Recovery and Development of Critical Loads of Acidity for Stream Ecosystems of the Adirondack Region of New York State

BACKGROUND The Adirondack region of New York has a history of relatively high atmospheric sulfur (S) and nitrogen (N) deposition (Greaver et al. 2012). Adirondack ecosystems have been impacted by these inputs, including soil and surface water acidification, and impaired health and diversity of forest vegetation and aquatic biota. Air quality management, through the Clean Air Act, the U.S....

Surface-water Quality in the Mohawk River Basin (Pilot RIBS/TMDL)

Problem The quality of surface water has important effects on human and ecological health. Surface water is an important drinking water source and is used for swimming, fishing, and recreation, and the quality of surface water can have profound effects on the health, diversity, and resilience of ecological communities. The New York State Department of Environmental Conservation (NYSDEC) is t...

Effects of acid-base chemistry on biology of lakes and streams in the Adirondack Mountains

BACKGROUND Watersheds of the Adirondack Mountains receive high levels of acid deposition resulting from atmospheric emissions of nitrogen and sulfur oxides. Acidic deposition has been shown to reduce acid neutralizing capacity (ANC) and calcium (Ca) concentrations, and increase acidity and aluminum (Al) concentrations in soils and surface waters, and affect forest health as well as fish and...

Groundwater Availability of the Northern Atlantic Coastal Plain

Background The North Atlantic Coastal Plain (NACP) covers a land area of approximately 34,000 mi 2 along the eastern seaboard of the United States from Long Island, N.Y., southward to the northern portion of North Carolina. This area is underlain by a thick wedge of sedimentary deposits that form a complex groundwater system in which the sands and gravels function as confined aquifers, and...

Flood-Inundation Maps for Four Stream Reaches, Ithaca, Tompkins County, New York

Problem The City of Ithaca, Tompkins County, N.Y., is in the process of developing a flood management plan for the streams that flow through the City. Flooding in the City is an annual problem caused by a variety of distinct and sometimes interconnected reasons. Flooding often is a result of snowmelt and rain during the winter and spring. Slow ice-melt and breakup can lead to ice jams and...

Problem The discharge of freshwater and associated loading of nutrients and other dissolved constituents from the Long Island aquifer system to surrounding estuaries and their tributaries are increasingly recognized as critical factors in the health of these ecosystems. However, further work is needed to scientifically characterize these factors and present them to the public in an...

Rockland County Water-Resource Assessment

INTRODUCTION • Concerns over the viability of the fractured bedrock aquifer that provides about 1/3 of Rockland County’s water supply prompted a 5-year study by the U.S. Geological Survey (USGS) to (1) define the hydrogeologic framework of the aquifer, (2) assess conditions within it, and (3) identify other potential sources of water for the County. The study was done in cooperation with...

Geohydrology of the Valley-Fill Aquifer in Upper Buttermilk Creek/Danby Creek Valleys, Town of Danby, Tompkins County, New York

Problem - The valley-fill deposits in Upper Buttermilk Creek/Danby Creek valleys are sources of water for many homeowners, farms, and small businesses that are in this valley. The aquifer was mapped by Miller (2000) and identified as one of the 17 aquifers in Tompkins County that needs to be studied in more detail. However, there is little geohydrologic data in the valley. A cluster of wells...

Airborne Geophysical Surveys over the Eastern Adirondacks, New York State

Airborne geophysical surveys were conducted in the eastern Adirondacks from Dec. 7, 2015 - Dec. 21, 2015, by Goldak Airborne Surveys. The area was flown along a draped surface with a nominal survey height above ground of 200 meters. The flight line spacing was 250 meters for traverse lines and 2500 meters for control lines. Here we present downloadable magnetic and radiometric (gamma spec
