Problem The Village of Dryden, rural homeowners, farms, and businesses in the Virgil Creek Valley tap several confined sand and gravel aquifers in the Virgil Creek valley in the town of Dryden . The valley contains a large moraine with complex stratigraphy consisting of continuous and discontinuous layers of till, lake deposits, and glaciofluvial sand and gravel. Sand and gravel units form the aquifers in the valley-fill deposits. There are at least three extensive confined aquifer units at various depths. However, little is known about (1) the location of recharge and discharge areas, (2) direction of groundwater flow, (3) extent of hydraulic connection between aquifer units, and (4) extent of surface- and ground-water...

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...

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...

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...

Detailed Aquifer Mapping Program in Upstate New York,
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 - The interaction between ground water and surface water within the Meads Creek watershed is not well understood, and the need for understanding the interaction has increased in recent years because of widespread concerns related to water supply, ground- and surface-water contamination, loss of wetlands due to development; and other changes in the watershed. In addition, flooding in the southern part of the watershed (mostly in Steuben County), where most development in the watershed has taken place, has highlighted the need for information about the drainage characteristics in the basin including the role of ground-water and surface-water interactions. Objectives - The objectives are (1) characterize...
