Problem - The Onondaga Lake Partnership (OLP) is committed to improving the water quality of Onondaga Lake. Onondaga County Soil and Water Conservation District (SWCD) has promoted best-management practices to decrease loads of nutrients and sediment from agricultural lands. Onondaga County Department of Water Environment Protection has abated many of the outflows from combined sanitary-and-storm sewers in the city of Syracuse and has upgraded treatment capabilities for removal of nutrients in effluent from the county's Metropolitan waste-water-treatment plant. These measures have fallen short of target levels of phosphorus and nitrogen loadings to Onondaga Lake because of inputs from nonpoint sources of pollution....

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 commercial and industrial sites. Currently, the Village of Endicott treats its water prior to distribution and can purchase water from other nearby municipal sources as needed. The village would like to find an additional source of clean water to supplement The most viable clean source is likely to be in sand-and-gravel-filled...

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 in Upper Buttermilk valley are finished in sand and gravel, indicating that there is a sand and gravel aquifer in, at least, part of the valley. The Upper Buttermilk Creek/Danby Creek valleys are "through valleys"-- a part of a valley where the bedrock floor rose to land surface and formed a preglacial surface-water divide....

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 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...

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 The City of Oneonta and surrounding area is the major population center in Otsego County, N.Y. and home to two colleges (SUNY Oneonta and Hartwick College). The public water supply draws on both surface-water and groundwater sources and serves 15,954 people in the City of Oneonta and parts of the surrounding Town of Oneonta (City of Oneonta, 2013). The remaining population uses domestic wells for water supply. The City is located in a section of Susquehanna River valley that includes confluences with three other major valleys: those of Charlotte Creek, Schenevus Creek, and Otego Creek. The study area covers 112 mi2 and includes the lower 2 to 5 miles of each of these valleys. The valley-fill deposits...

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 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...

Problem - USGS regional framework characterizations have been used effectively in many studies. However, lack of framework accuracy, particularly at smaller scales, continues to cause problems that may involve: (1) sizing of pumps and other aspects of wellfield design and maintenance, (2) projection of local-scale water-level changes, and (3) projection of interactions with other hydrologic stresses. The objective of this study is to improve framework representations by implementing continuous-recording observation wells at SCWA wellfields, in concert with the SCWA record of pumping and other regional USGS data. As necessary, the implications of framework revisions on such topics as safe aquifer yield, source-area...

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 construction paths using advanced surface and borehole geophysical methods. The NYCDEP needs to determine the source of groundwater and surface water and their possible relation to leakage from the Delaware Aqueduct in upstate New York. The Delaware Aqueduct, which supplies a significant portion of New York City's water supply, has...

Problem Perchlorate detected in a shallow supply well within the southern portion of the Locust Valley Water District (LVWD) has prompted interest in determining the possible existence of a deeper confined aquifer (North Shore Aquifer) that may be protected from shallow contamination (fig. 1). Previous USGS studies in this area indicate the northern part of Nassau County has a complex hydrogeologic framework (Stumm and others, 2004). A previously mapped buried glacial valley may extend and be present at this location. If such a buried valley exists, all Cretaceous age deposits (Magothy aquifer, Raritan clay, and Lloyd aquifer) may have been eroded and Pleistocene-aged deposits including the North Shore aquifer...

Problem - Several supply wells in Oswego County were evaluated by the USGS in 1999 by using stable oxygen and hydrogen isotopes and chlorofluorocarbon (CFC) age dating techniques. For two municipal well sites (the Villages of Sandy Creek and Lacona, and the Village of Pulaski) that tap a shallow, unconfined aquifer (typically 20-50 ft thick) there were significant discrepancies between ground-water recharge ages determined by chemical data and those determined by ground-water-flow models developed by independent studies. The significant discrepancies between the times of travel of ground water as determined by numerical ground-water-flow modeling and geochemical dating techniques in Oswego County need to be understood...

Problem - The Town of Caroline needs geohydrologic data in two major valley-fill aquifers within the town in order for planners to develop a strategy to manage and protect their water resources. Interest in the interaction between ground water and surface water has increased in recent years as a result of widespread concerns related to water supply. The need to better understand how the development of one water resource affects another will increase as development in Tompkins County intensifies. Upper Sixmile Creek/West Branch Owego Creeks valleys and Lower Sixmile Creek/Willseyville Creek valleys in the Town of Caroline were selected to be studied because they are undergoing increasing development; and most people...

Problem - The Village of Pulaski in Oswego County, N.Y., obtains its water supply from groundwater that drains under gravity from an unconfined aquifer into three shallow dug wells. The well field is in an area where groundwater discharges to springs along the west edge of the Tug Hill Aquifer, which is comprised of beach and kame deposits of sand and gravel. A numerical groundwater model was constructed previously to simulate groundwater conditions in part of the Tug Hill Aquifer near the Pulaski well field. The modeling work was part of a wellhead protection study to develop a plan to protect the groundwater resources of the Village of Pulaski's public water-supply system. In addition, the USGS, in cooperation...
