Problem - The Ithaca Subdistrict Office of the U.S. Geological Survey (USGS) is providing technical assistance to the USGS, Biological Resources Division (BRD), at the Tunison Laboratory of Aquatic Science (TLAS) in an investigation of the availability of fresh ground water. An expansion in the water supply at the laboratory is needed for a proposed spawning facility for salmon strains that are viable for natural fisheries in the Great Lakes region. The hydrogeology of the area is a complex of moraine and outwash deposits west of Cortland, N.Y. Data from existing wells at the laboratory indicate that well screens may readily clog from precipitated minerals. A review of the hydrogeology of the area, including...

Problem - The New York City Department of Environmental Protection (NYCDEP) is constructing or proposing water tunnels under New York City and areas of southeastern New York (Hudson River Basin). These tunnels can intersect faults and fractures that produce large amounts of ground water. For example, one tunnel excavation intersected fractures that produced over 200 gallons per minute of ground-water flow into the tunnel. Consequently, there is a need to determine the potential of intersecting ground-water producing fractures during tunnel excavation. The use of advanced borehole geophysical techniques by the USGS during tunnel excavations in northern Queens County demonstrated that geophysical techniques can...

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 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....

Background The U.S. Geological Survey (USGS) has characterized fractures, foliation, and fractured-rock groundwater flow penetrated by test boreholes in crystalline bedrock underlying Manhattan Island, New York County, New York since 1998. New test boreholes will be drilled on Roosevelt Island in New York County for a Cornell University geothermal test project. Cornell University is partnering with the USGS in a cooperative program to use advanced borehole geophysical methods to characterize the fractured-rock groundwater flow system on the southern end of Roosevelt Island, and compare it to the flow system on nearby Manhattan Island. The USGS will assess the hydrogeology of the area and determine the strike and...

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...

Problem - The U.S. Geological Survey (USGS) provided technical assistance between 2001 and 2013 to the U.S. Environmental Protection Agency (EPA) in an investigation of the presence of chlorinated solvents (trichloroethylene and degradates) in ground water in the Middle-to-Lower Devonian and Upper Silurian carbonate bedrock southwest of Auburn in Cayuga County, N.Y. Pieziometric and water-quality data from the wells indicate that contaminants may have migrated in the bedrock as far as 7 miles toward discharge areas that are in an adjacent surface-water basin. The ground-water contamination site was added to the Super Fund priority list in 2003. Objectives - The objective of the work is to characterize the stratigraphy,...
