Problem - During 2003-07, a precipitation-runoff watershed model with water-quality components was developed to assess pollutant sources and loadings to Onondaga Lake, and to assist water-resources managers in making decisions regarding the selection and location of mitigative measures to maximize load reduction for a given effort. In the absence of chemical loading rates that were specific to the Onondaga Lake Basin, the model was calibrated to estimated loading rates that were derived from a review of scientific literature. During 2005-08, an intensive water-quality study of the basin was conducted to provide basin-specific data that, among other uses, could be incorporated into the watershed model and provide...

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 Lloyd aquifer, and several gaps in the confining units that overlie the North Shore and Lloyd aquifers. Five areas of salt-water intrusion have been delineated, two of which are considered active. Several public-supply wells on the Manhasset Neck Peninsula have been shut down in the past as a result of saltwater intrusion....

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, and type of glacial deposits (fig. 1). In this study, the name “Tug Hill glacial aquifer” refers only to the 29-mi-long northern and central parts of the Tug Hill aquifer. (The southern part was not included in this investigation.) For this study, the division between the northern and central parts of the aquifer was placed...

Problem - The New York City Department of Environmental Protection (NYCDEP) Stream Management Program, in cooperation with local Soil and Water Conservation Districts, is implementing stream-restoration demonstration projects to decrease channel bed and bank erosion and improve water quality (lower suspended sediment and turbidity) in several priority streams of the Catskill Mountain Region (Fig. 1). A variety of issues relating to (a) the hydraulic geometry of stable and unstable stream channels, (b) validation of underlying assumptions used to characterize channel stability and design, and (c) the effects of restoration on stream-channel geomorphology, stability, biota, and sediment transport have not been...

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...

Background The New York State Department of Environmental Conservation (NYSDEC) and Adirondack Lakes Survey Corporation (ALSC) repeatedly surveyed fish assemblages and characterized water chemistry from 44 to 52 lakes during the periods 1984-1987 and 1994-2005, and 2008-2012 to document the regional effects of acidic deposition and potential recovery associated with the 1990 Clean Air Act Amendment (CAAA) under the Adirondack Long-Term Monitoring (ATLM) Project. An initial analysis of changes in fish assemblages between the periods 1984-1987 and 1994-2005 noted modest and mixed recoveries, identified five fish-community response/recovery classes, and helped to devise a fish-community index based on species acid...

Background Forested watersheds in the southwestern Adirondack Mountains of New York received some of the most acidic deposition in North America from the 1970s through much of the 1990s (NADP 2005). Thus it is not surprising that associated effects on surface-water quality and ecosystems in lakes and streams of the southwestern Adirondack Mountains of New York were investigated to various extents over the past 35 years; first to document acidification effects and then to evaluate potential recovery. In fact, evidence of adverse impacts on water quality and aquatic ecosystems across the region provided much support for implementation of the Clean Air Act (CAA) of 1990. Although the underlying effect mechanisms were...

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 no longer valid by the Village of Dryden owing to development in the basin, which presumably has increased runoff and, in at least one instance, encroached on the floodplain. In addition, similar data for lower, intermediate, and higher floods are non-existent. Emergency responders and the public would benefit from a series...

Introduction Mosquitoes are the principle vector of the West Nile Virus (WNV) which causes infections in humans and animals and has emerged as a public health threat throughout Long Island, NY. The WNV was first detected among birds and mosquitoes by the Suffolk County Department of Health Services (SCDHS) in 2000. In response to the public health concern, the USGS in cooperation with the SCDHS, began a 3-year study in 2002 to sample surface waters in selected wetlands for insecticides which were sprayed seasonally from a truck or helicopter as part of the county's vector-control program. These insecticides include Altosid (methoprene) and Scourge [1:3 ratio of resmethrin and piperonyl butoxide (PBO)]. Methoprene...

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, Pennsylvania, and New Jersey. The focus of this research and monitoring program has recently shifted toward studies of the rapidly declining American eel (Anguilla rostrata) populations in rivers of the tri-state region. There are many factors that could potentially cause the observed declines in local and continental populations of...

Problem : Occurrence and persistence of emerging contaminants in groundwater flow in Suffolk County, New York Objectives: This project will monitor groundwater from selected SCWA supply wells for compounds indicative of anthropogenic sources, which are of increasing public concern. Approach: Groundwater-flow information, well-construction details, and distance from treated wastewater (including municipal and industrial) discharge areas will be used to select 12 wells that are along the paths of groundwater flow from discharge sites. Groundwater samples will be analyzed for roughly 100 common organic contaminants­­­­­—including pharmaceuticals, hormones, and wastewater indicators—that could potentially pass through...

Problem Dissolved oxygen (DO) is an important indicator of water quality that until recently has been cost-prohibitive to monitor extensively in both space and time. Continuous water-quality data, particularly in coastal environments with bidirectional tidal flow, is necessary for resource managers to understand the dynamic changes in water quality that occur tidally, daily, seasonally, and during aperiodic events. In the estuaries surrounding Long Island, such events may include wastewater treatment plant failures, harmful algal blooms, and extreme weather. The U.S. Geological Survey (USGS) has extensive experience with continuous water-quality monitoring at fixed locations along the coast that provides valuable...

Project Summary. The Western Adirondack Stream Survey (WASS), conducted in 2003-2005, showed that acidic deposition was causing toxic forms of Al to move from soils to streams in 66% of the 565 watersheds assessed in the study region. The WASS encompassed only 20% of the Adirondack region, and for the remaining 80% (referred to hereafter as the East-Central Adirondack region), there is little information on the extent of soil and stream acidification. Based on lake-chemistry data, acidification in the East-Central Adirondack region has been considered minimal relative to the Western Adirondack region. However, some lake acidification has been identified, and WASS results showed that lake acidification under...

Background Every day, the New York City Department of Environmental Protection (DEP) supplies more than one billion gallons of drinking water to more than nine million people. To do this, the DEP maintains an extensive network of reservoirs and aqueducts. A major part of this system, the West of Hudson (WOH) network, in the Delaware and Hudson River drainages, includes six reservoirs (fig. 1) – Ashokan, Cannonsville, Neversink, Pepacton, Rondout, and Schoharie – which were constructed from the early 1900s to the 1960s and have an estimated combined storage capacity of more than 460 billion gallons. Problem and Objective The daily and seasonal management of the WOH reservoirs by DEP depends on accurate bathymetric...

Problem Long Island’s sole-source aquifer system, which includes the Lloyd, Magothy, Jameco, and upper glacial aquifers, supplies groundwater to over 2.8 million people. As a coastal aquifer system, it is susceptible to saltwater intrusion. Past pumpage and sewering (fig. 1) resulted in increased salinity in most aquifers in all counties (Buxton and Shernoff, 1999; Misut and others, 2004; Misut and Aphale, 2014). Simulation of drought has predicted increasing salinity in the lower part of the glacial aquifer of the North Fork of Suffolk County (Misut and others, 2004). In addition, simulation of future well pumpage in Queens County by the U.S. Geological Survey (USGS) has predicted increasing salinity in the Magothy...

Introduction Public-water systems at Springville and Yorkshire/Delavan, N.Y. along Cattaraugus Creek draw from local groundwater resources and serve about 5,500 people (U.S. EPA SDWIS database). The remainder of the population obtains water from domestic wells, many of them completed in glacial aquifers. A Cattaraugus Creek tributary valley (Buttermilk Creek) to the south is the site of the West Valley low-level radioactive waste burial site (part of the Western New York Nuclear Service Center). Numerous investigations of glacial geology and hydrogeology have been performed at this site (for example, Prudic and Randall (1977), LaFleur (1980), and Prudic (1986)) and glacial mapping has included the surrounding area...

Background Since 1980 the U.S. Geological Survey has conducted a Detailed Aquifer Mapping Program in upstate New York, first in cooperation with the New York State Department of Health (NYSDOH), and later in cooperation with the New York State Department of Environmental Conservation (NYSDEC), Division of Water. The objective of this program is to define the hydrogeology of important stratified-drift aquifers in upstate New York, and to present the information as individual sets of maps at a 1:24,000 scale. Each published report from this program describes the hydrogeology of a specific aquifer or section of aquifer, and depicts selected hydrogeologic characteristics. These reports form the foundation of NYSDEC's...

Problem The groundwater supply of Nassau and Suffolk Counties is prone to contamination from past and current land uses, including practices related to agriculture, industry, and residential development, because the soils and underlying sediments are generally composed of sandy, permeable materials that allow contaminants to move readily from the land surface into the groundwater below. Of increasing concern are the human-derived contaminants stemming from on-site disposal of residential wastewater and industrial processes. The centralized distribution of water through purveyors to most residents provides them with a reliable source of potable water that is consistently monitored at the wellhead. However, increased...

PROBLEM The valley-fill aquifers in the West Branch Cayuga Inlet and Fish Kill valleys (designated as aquifer 15, fig.1), within the Town of Newfield, were mapped by Miller (2000) and identified as one of 17 unconsolidated aquifers in Tompkins County that need to be studied in more detail. The valley-fill in the West Branch Cayuga Inlet and Fish Kill valleys contain a heterogeneous mix of glacial deposits and recent alluvium under mostly unconfined conditions, but may they be under confined conditions in some places. The valley-fill deposits are sources of water for the Village of Newfield, homeowners, farms, and small businesses in these valleys. The Village of Newfield has recently been searching for another location...

Background Although New York State has more than 70,000 miles of streams and rivers, little is known about the status, distribution, and trends of mercury (Hg) levels in stream fish, or the environmental drivers of these patterns. Streams and their riparian zones provide critical habitat for fish, birds, mammals, reptiles and amphibians, and serve as the interface between aquatic and terrestrial Hg transfer, transformations (most notably methylation) and bioaccumulation. Importantly, monitoring data from lakes (e.g., Simonin et al. 2006) does not transfer reliably to streams because of fundamental differences in Hg cycling and bioaccumulation processes. An assessment of fish Hg bioaccumulation focused on New...
