Organic Wastewater and Pesticide Monitoring at Key Points in the New York City Reservoir System

Problem Samples were collected from 10 Key Point sites in the New York City Reservoir system as part of the cooperative USGS-New York State Department of Environmental Conservation (NYSDEC) statewide pesticide monitoring project ( Phillips and others, 2000). Ten pesticides were detected in the key-point samples collected between January 1999 and September 2000 - the herbicides atrazine, meto...

Documenting Hydrogeologic Information Obtained from Deep-Borehole Drilling in Suffolk County, New York

Background Borehole drilling and well-installation are costly procedures, and securing funding for new well installation for the sake of research is often difficult.The Suffolk County Water Authority (SCWA) maintains a large network of deep wells for public supply that is constantly being upgraded as water demands increase. During the drilling process, contractors record drillers...

Estimating Loading Above and Below Agricultural Best Management Practices (BMPs) and Combined Animal Feeding Operations (CAFOs) in the Genesee River Watershed

The current information available for the Genesee River and watershed is insufficient to assess if the Beneficial Use Impairment (BUI) delisting criteria for the Rochester Embayment Area of Concern (AOC) can or have been met. With on-going and future projects that are implementing best practices to control soil erosion and the reduction of nutrients that reach the Rochester Embayment, the...

Detailed Aquifer Mapping in Wayne County, New York, The Fairport-Lyons Channel Aquifer

Introduction Detailed mapping of the glacial aquifer within the buried Fairport-Lyons bedrock channel in southern Wayne County, N.Y. is the latest study in the cooperative Detailed Aquifer Mapping Program between the U.S. Geological Survey (USGS) and the New York State Department of Environmental Conservation (NYSDEC). The aim of the program is to map the extent of glacial aquifers in New Yo...

Use of telemetry to assess potential effects of Schoharie Reservoir waters on trout populations in the Upper Esopus Creek

Background - Turbid waters originating in the Schoharie Reservoir allegedly impair habitat and resident trout populations in Upper Esopus Creek; however, to date no scientific studies have documented adverse affects of altered thermal, suspended sediment (turbidity), and flow regimes on survival, growth, or behavior of trout or the health of their populations. The 424 mi2 Esopus Creek...

National Water Quality Assessment Program -- Water-Quality Assessments of Principal Aquifers

A major focus of the NAWQA Program in its second decade (2002-2013) is on regional- and national-scale assessments of groundwater-quality status and trends in principal aquifers. The U.S. Geological Survey Office of Groundwater has identified 62 principal aquifers in the U.S. (U.S. Geological Survey, 2003). About 1/3 of the Nation's principal aquifers are the focus of water-quality assessments...

Quantitative assessment of water quality in the Upper Esopus Creek using fatty acid content of periphyton

Problem - The Esopus Creek is located in the Catskill Mountains of New York State and is part of the New York City (NYC) drinking water supply system. The basin was dammed in 1915 to form the Ashokan Reservoir splitting the creek into Upper (upstream of the reservoir) and Lower segments. The Schoharie Reservoir, located 27 miles north of the Ashokan Reservoir, supplies water to Upper Esopus...

Evaluation of a barrier-island breach created by Hurricane Sandy at Fire Island National Seashore, N.Y.

Hurricane Sandy has created three open breaches in the barrier island system along the south shore of Long Island, N.Y. In response, the National Park Service has sought assistance from the U.S. Geological Survey (USGS) New York Water Science Center (NYWSC) to help evaluate the open breach condition in Federal Wilderness near the Old Inlet area of Fire Island National Seashore, N.Y. The NYWSC...

Didymosphenia geminata in the Upper Esopus Creek: Seasonal changes in density and distribution, controlling environmental factors, and potential ecosystem impacts

Background The invasive diatom Didymosphenia geminata (didymo) has historically been a wide-spread, but rare, micro algae found in moderately flowing cold-water streams of North America, Europe, Asia, and (more recently) New Zealand. Demographic patterns of didymo have recently changed resulting in greater spatial coverage and temporal persistence (e.g. blooms) in streams worldwide. Didymo...

Effects of recreational flow releases on natural resources of the Indian and Hudson Rivers

The New York State Department of Environmental Conservation (NYSDEC) is developing a unit management plan/environmental impact statement (UMP/EIS) for the Hudson Gorge Primitive Area, an area of Forest Preserve land encompassing a scenic stretch of the Hudson River in the Adirondack Park. Two goals of the UMP/EIS are to inventory natural resources and ecosystems and take actions to protect...

Delineation of the Freshwater-Saltwater Interface at Selected Public-Supply Wells Using Advanced Surface and Borehole Geophysical Techniques, in Eastern Suffolk County, New York

The combination of a complex hydrogeologic framework, narrow land masses surrounded by saltwater, and extensive ground-water public-supply pumpage has produced localized areas of elevated chloride concentrations in ground water. This project uses advanced surface and borehole geophysical methods to determine the extent of saltwater intrusion and road-salt plumes at selected sites in eastern...

Delineation of Groundwater Flow, Lithology, Faults, and Fractures Along Existing and Proposed Water Tunnel

Problem The New York City Department of Environmental Protection (NYCDEP) has asked the U.S. Geological Survey (USGS) to assist in two major studies: 1) delineation of the source(s) of shallow groundwater and the extent that the Delaware Aqueduct is contributing to local flooding issues, and 2) delineation of the structural, geologic, and hydrologic conditions along proposed tunnel...
