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.

Development and Implementation of a Baseflow (groundwater) Monitoring Network for the Pepacton Watershed

The Pepacton watershed is an integral part of New York City's public-water supply system. Most of the watershed is within Delaware County with headwaters of some of its eastern tributary streams originating in Greene and Ulster Counties. Land use varies from dairy farms in the northern portion of the watershed to extensive forested areas in the south with small rural communities interspersed...

Sediment toxicity and status of benthic invertebrate communities in the St. Lawrence River and its tributaries within the Massena Area-of-Concern

Background Past water-quality issues in the St. Lawrence River at Massena, NY resulted in a determination that selected beneficial uses were impaired in a surrounding Area of Concern (AOC) and on the Canadian side of the international boundary (Cornwall, Ontario). The benthic macroinvertebrate community or “benthos” Beneficial Use Impairment (BUI) was designated degraded because impairment...

Estimating chronic toxicity of waters from the St. Lawrence River at Massena Area-of-Concern using two plankton species

Background Past water-quality issues in the St. Lawrence River at Massena, NY resulted in a determination that selected beneficial uses may be impaired in a surrounding Area of Concern (AOC) and on the Canadian side of the international boundary (Cornwall, Ontario). The plankton (phytoplankton zooplankton) Beneficial Use Impairment (BUI) was so designated because impairment metrics were...

Development and Operation of Groundwater, Surface-Water, and Water-Quality Monitoring Networks in Richmond, New York, and Bronx Counties, New York

Problem Previous hydrologic studies have indicated that there may be sufficient water resources underlying Richmond, New York, and Bronx Counties for use as a supplemental water supply by the New York City Department of Environmental Protection (NYCDEP) in times of a drought or other water shortage. Unfortunately, comprehensive data on the quantity and quality of the Counties' water resources...

Development of GIS datasets for selected aquifers in New York

Problem - Since the 1980s, the U.S. Geological Survey (USGS) has mapped over 30 sand and gravel aquifers in upstate New York at the 1:24,000-scale. These mapped aquifers include both the primary and many of the principal aquifers as designated by the New York State Department of Environmental Conservation. Although the 1:24,000-scale maps are valuable in their present form, their usefulness is...

The Effects of Watershed and Stream Liming on Mercury Dynamics at Honnedaga Lake

Problem The Adirondack region of New York has 128 lakes that are listed as impaired by acidity under section 303(d) of the Clean Water Act. Acidity can limit the survival and reproduction of native fishes such as brook trout (Salvelinus fontinalis). Chronic and episodic acidification also stresses fish, aquatic macroinvertebrates, and other biota of inflowing tributaries of these and many...

Hydrogeology of the Tully Valley Mudboil Area, Southern Onondaga County, New York

Problem The Tully Valley, located in southern Onondaga County has been the source of sediment and brackish water discharge to Onondaga Creek, a tributary to the Seneca and Oswego Rivers and eventually Lake Ontario. Information on the origin of the Tully Valley mudboils, their persistence, and the possible extent of their migration within the Tully Valley is needed to mitigate or remediate (1)...

Geohydrology of the Valley-Fill Aquifer in the Nanticoke Creek Valley near Endicott, New York

Problem The Village of Endicott relies on wells that supply ground water from sand and gravel aquifers within the Susquehanna River valley. Localized contamination in the Village of Endicott and elsewhere in the Susquehanna River Valley has been documented by U. S. Environmental Protection Agency (USEPA) and the New York State Department of Environmental Conservation (NYSDEC) from a number of...

Assessing American Eel Populations in Tributaries to the Upper Delaware River

American Eel (Anguilla Rostrata) Background The U.S. Geological Survey (USGS) has worked in cooperation with The Nature Conservancy (TNC) over the past 11 years to study the effects of channel geomorphology and impoundments on the distribution of common and rare mussels in the Neversink River and to characterize fish assemblages in tributaries to the Upper Delaware River in New York,...

Effects of Stream Restoration and Bank Stabilization on Suspended Sediment in Tributaries to the Upper Esopus Creek

Introduction The upper Esopus Creek watershed is located in the eastern Catskill Mountains of New York State and covers 497 km2 from Slide Mountain, the highest peak in the Catskills at 1,274 m, to the Ashokan Reservoir at 193 m elevation (fig. 1). Suspended sediment and turbidity are primary water quality concerns in the Ashokan Reservoir watershed, part of the New York City Catskill-Delaw...

Estimating Acute and Chronic Toxicity of Waters from the Rochester Embayment Area of Concern Using Two Plankton Species

Background Discharges from non-point sources, municipal and industrial point sources, and combined sewage overflows over the last century resulted in elevated levels of heavy metals, conventional pollutants, phosphorus, and toxic organic contaminants in water and sediments of the Lower Genesee River and Rochester Embayment. As a result, the zooplankton and phytoplankton or “plankton”...

Estimation of PCB Loads from the Black River Basin to Lake Ontario, NY

Problem - There is a stated need to provide information on loading of persistent toxic pollutants to Lake Ontario from New York tributaries. The information is specifically required for the Lake Ontario Mass Balance Model, which is an integral part of the long-term Great Lakes research. The project described here is designed to demonstrate a cost-effective approach for estimation of loads of...
