DEC collaborators collect fish from a Niagara River tributary using an electrofishing boat The New York State Department of Environmental Conservation (NYSDEC) and Department of Health (NYSDOH), and the U.S. Geological Survey (USGS) are gathering data on chemical contaminants in fish from multiple Areas of Concern (AOCs) in New York State and plan to use this information to evaluate fish consumption advisories, which are a critical component of most removal criteria for “Restriction on Fish and Wildlife Consumption” beneficial use impairments (BUI). This second project is being implemented in the Niagara River AOC during summer 2018. It will help identify sources areas for contaminants in fish and to determine...

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 metrics were unavailable or inconclusive. Recent sampling efforts by New York State Department of Environmental Conservation (NYSDEC) as part of their Rotating Integrated Basin Studies (RIBS) program indicate that macroinvertebrate communities in some sections of the St. Lawrence River and its tributaries in the Massena AOC are...

Background 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 drainage area of Upper Esopus Creek, between the source (Winisook Lake) and the Ashokan Reservoir is approximately 192 mi2. The Schoharie Reservoir, located 27 miles north of the Ashokan Reservoir, also supplies water to Upper Esopus Creek (and to the Ashokan Reservoir) via the Shandaken tunnel. Waters from the Schoharie watershed enter Upper Esopus Creek at the Shandaken portal and travel 18 km before entering the Ashokan...

Background: Harmful algal blooms (HABs) are increasingly a global concern because they pose a threat to human and aquatic ecosystem health and cause economic damages. Cyanobacterial HABs (CyanoHABs) represent a substantial threat to drinking-water supplies, aquatic ecosystem health, and safe recreational uses of freshwater resources in New York. Toxins produced by some species of cyanobacteria (called cyanotoxins) can cause acute and chronic illnesses in humans. Aquatic ecosystem health also is affected by cyanotoxins, as well as low dissolved oxygen concentrations and changes in aquatic food webs caused by an over-abundance of cyanobacteria. For these reasons, the New York State Department of Environmental Conservation...

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 unavailable or inconclusive. Recent investigations, however, suggest that plankton communities are relatively healthy and no longer threaten the local ecosystem. Thus, the BUI for plankton may now be outdated in all, or parts of, the St. Lawrence River in the Massena AOC. The primary goal for the Massena (and Cornwall) Remedial Action...

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 throughout the watershed. Sound management of the water resources in the region necessitates development of hydrologic data networks that will document current water-quality conditions in relation to watershed characteristics such as land use. Ground-water discharge to streams accounts for most of the water reaching the New...

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 limited because the important features on the maps, namely aquifer boundaries and the surficial geology, are not available as digital geographic information system (GIS) datasets. Objectives - To maximize the usefulness of the aquifer maps, GIS datasets of the 1:24,000-scale aquifer maps will be developed. To further increase...

Problem– Lake Ontario experienced period-of-record (1918-2017) maximum monthly average water levels during May through July 2017. NOAA lake gages recorded instantaneous peaks-of record, 249.2 at Olcott, 249.1 at Rochester, and 249.0 at Oswego and St. Vincent. These high water levels along with wind-generated waves caused flooding of thousands of residences and businesses and the erosion of miles of shoreline along the southern and eastern shorelines of the Lake. During the second week of July 2017, the USGS installed 14 temporary water-level gages and monitored this flooding through the lake’s recession. This network of water-level gages, in combination with the NOAA sites, provides a dense coverage of the lake...

PROBLEM There are more than 60 organizations and agencies collecting water-quality data on Long Island. The types of database management that are used to store and archive regulatory and non-regulatory data vary from paper forms to spreadsheets to State and Federal databases, and there is minimal communication between these systems. As a result, those interested in analyzing data may be unaware of what data exist and how those data can be obtained without a Freedom of Information Law request. A unified data sharing system that provides multiple levels of sensitive and non-sensitive data storage and dissemination is needed. This system should link the various databases and interact through web services to provide...

Introduction Detailed mapping of the valley-fill aquifer within the Owasco Inlet valley and adjacent tributary valleys in Cayuga County (Towns of Moravia and Locke) and Tompkins County (Town of Groton) is the latest study in the cooperative Detailed Aquifer Mapping Program between the US Geological Survey (USGS) and the New York State Department of Environmental Conservation (NYSDEC). The aim of the program is to map sand and gravel aquifers in New York State at a scale of 1:24,000. This information is used by NYSDEC Division of Water and others to delineate groundwater contributing areas, assess potential threats to aquifers from both point and non-point sources, respond to contamination from spills or leaks...

Problem - The demand for water in New York State is unevenly distributed. Because increasing competition for local supplies could lead to shortages, it is expedient to know how and where water is withdrawn, delivered, and used. There are many dimensions to water-use issues, and all should be considered to develop a full understanding of the use and delivery of water in the State. In order to apply water-use information to problems of water-demand management, many data elements need to be collected and stored in a convenient location and format. The categories of water use most commonly considered include public-water supply, domestic, thermoelectric power generation, industrial, irrigation and, to a lesser degree,...

The coastal areas of southeastern New York (fig. 1) are highly vulnerable to tidal flooding (fig. 2). Timely evacuation of people from flood-threatened areas in advance of approaching hurricanes and nor'easters (northeast coastal storms) requires adequate flood-warning time. To begin addressing this need for immediate information on coastal flooding, the U.S. Geological Survey (USGS), in cooperation with the Town of Hempstead Department of Conservation & Waterways, Village of Freeport, and New York State Department of Environmental Conservation, has operated a network of real-time tidal water-elevation and meteorological stations since 1997 in the coastal areas of Long Island and New York City. Each tidal water-elevation...

Problem Coastal communities are susceptible to damage from coastal storms and associated storm surge, and although tidal wetlands provide a buffer against shoreline erosion and aid in shoreline stabilization, they too are vulnerable to the action of storms. Tidal wetland dynamics need to be better understood, as they are also intrinsically valuable as nursery, feeding, and refuge areas for many commercial and recreational fisheries, and significantly contribute to the base of the marine food web. Wetlands trap sediments, reduce turbidity, and absorb nutrients and pollutants thereby improving water quality, and they provide many recreational opportunities. Tidal wetland stability needs to be assessed using a sediment...

Problem The presence of pathogens in Long Island marine embayments and the hazards they pose to marine resources and human health is of increasing concern. Many waterbodies on the New York State Section 303(d) List of Impaired Waters have pathogens listed as the primary pollutant that are suspected to originate from urban/storm runoff. There is neither a clear understanding of the relative magnitude and geographic origin of sources of loadings of pathogens (from urban/storm runoff, submarine groundwater discharge, etc) on Long Island, nor clear understanding about the host organisms from which they originate (such as human, mammals, or birds). Pathogen loads to specific embayments are affected by watershed land-use,...

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” communities were designated as one of fourteen Beneficial Use Impairments (BUI); i.e., the resource was either impaired or in need of assessment in the Rochester Embayment Area of Concern (AOC). The Rochester Embayment Remedial Action Committee (RAC) was formed by the New York State Department of Environmental Conservation (NYSDEC)...

The United States Geological Survey (USGS), in cooperation with the New York State Department of Environmental Conservation (NYSDEC), monitors a network of observation wells throughout New York to provide current information on the effect of climatic conditions on groundwater levels. At present (2015), there are 95 observation wells in unconsolidated and bedrock aquifers, all of which are equipped with telemetry for near real time data transmission. Daily groundwater levels and hydrographs for each well site are available online in the National Water Information System (NWIS). In addition, monthly assessments of ground-water conditions, based on frequency statistical analysis of the monitoring data, are provided...

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 Rockland County and the New York State Department of Environmental Conservation. • Population growth in Rockland County to nearly 300,000 people has been paralleled by significant hydrologic changes over the past 50 years –water demand and impervious surface area have increased, and sanitary sewers now serve most areas and discharge...

The growth of temperate forests is typically limited by the availability of nitrogen. Elevated concentrations of nitrate in some Catskill Mountain streams, which are tributary to New York City's water-supply reservoirs west of the Hudson River, indicate that the forests of this region are at the early stages of nitrogen saturation. That is, nitrogen is available in excess of the amount utilized by vegetation and soil microorganisms in the forests. Nitrogen saturation is a concern because the mobile nitrate that moves through soil is accompanied by other nutrients such as the base cations calcium and magnesium that are necessary for forest growth but are present in short supply in some Catskill soils. And, nutrient...

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 watershed is a tributary to the Hudson River in the south-central Catskill Mountains of New York State and is often considered to be two systems separated by the Ashokan Reservoir. The Upper Esopus Creek is considered the reach between its source, Winisook Lake, and the reservoir. Flows in the Upper Esopus Creek are supplemented by...

Problem - The New York State Departments of Environmental Conservation (NYSDEC) and Health (NYSDOH) are concerned about Problem - The New York State Departments of Environmental Conservation (NYSDEC) and Health (NYSDOH) are concerned about ground-water contamination in the carbonate-bedrock aquifers, especially relating to the inadvertent introduction of volatile organic compounds (VOCs) and manure to these aquifers. Groundwater can flow very quickly with minimal filtration or adsorption through solution-widened fractures in carbonate-bedrock aquifers. Therefore, large amounts of water and associated contaminants can move long distances, sometimes in short periods of time, and affect large areas. If these underground...
