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 York State at a scale of 1:24,000. This information is used by NYSDEC Division of Water and others for delineation of groundwater contributing areas, assessing potential threats to aquifers from both point and non-point sources of pollution, responding to contamination from spills or leaks from underground storage facilities,...

Background - Detailed mapping of the glacial aquifer within the Chemung River and adjacent tributary valleys in Eastern Chemung County 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 glacial aquifers in New York State at a scale of 1:24,000. This information is used by NYSDEC Division of Water and others for delineation of groundwater contributing areas, assessing potential threats to aquifers from both point and non-point sources, responding to contamination from spills or leaks from underground storage facilities, and providing information...

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 The unconsolidated aquifer in Enfield Creek Valley (fig. 1) was mapped by Miller (2000) and identified as one of 17 unconsolidated aquifers in Tompkins County that needs to be studied in more detail. Well records in Enfield Creek valley indicate that the northern part of Enfield Creek valley contains sand and gravel deposits which may be under unconfined conditions in some areas, confined in others, or both; and the southern part of the valley contains mostly sand and gravel under unconfined conditions. The valley will probably undergo increased development as the population in Tompkins County increases and spreads out from metropolitan areas. However, there is little geohydrologic data in the valley....

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 Town of Riverhead in the northeastern Suffolk County includes rural farmland and suburbs and is bounded by the Long Island Sound to the north and Peconic Bay to the southeast. Riverhead’s close proximity to saline embayments and its location along the northeastern discharge area for Long Island’s groundwater flow system makes it vulnerable to saltwater intrusion. Several public-supply wells in Riverhead have experienced increased chloride concentrations recently due to the encroachment of saltwater. Riverhead is underlain by a sequence of unconsolidated deposits ranging in age from Pleistocene to Upper Cretaceous that overlie a basement complex of Precambrian bedrock. These deposits are part of Long...

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 - 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...
