Summary The U. S. Geological Survey (USGS) will conduct simulations using existing aquifer data, including geologic logs from vertical profile borings (VPBs) and well installations, water levels, and pump test data available from the water districts for these production wells. Subsequently USGS will incorporate data from a groundwater pump test and additional data from new VPBs and monitoring wells. Using particle tracking maps, USGS will illustrate the spatial configuration of the capture zone and percentage of capture of the shallow and deep plumes in each production well. The model area will be limited to achieve these objectives and make maximum use of available sampling locations in the region. USGS will...

Background In recent years, more and more people have become concerned about Long Island's supply of freshwater. Currently, there is no comprehensive, island-wide resource that summarizes recent U.S. Geological Survey (USGS) research related to the Island's aquifer system. A webpage will be developed by the USGS that will compile published data from the hydrologic-surveillance program, in place since the mid-1970’s, and various USGS sources, and supplement this information with more recent seasonal and annual hydrologic technical assistance will be provided to the Suffolk County Water Authority (SCWA) to help them produce an easy to understand annual report that will provide a snapshot of the state of Long Island's...

Background: A sequence of gently dipping carbonate bedrock - the Bertie Formation, Akron Dolostone, and Onondaga Limestone crop out along a 2- to5-mile wide band in western and central New York. These bedrock units trend east-west for 250 miles across the State and form extensive carbonate-bedrock aquifers which transmit and yield water from solution-enlarged fractures, bedding planes, and other openings (Olcott, 1995). Bedding planes or sub-horizontal fractures typically are the most enlarged and important water conduits. Karstic features such as sinkholes, swallets, solution channels, and caverns can locally transmit large amounts of surface water into the ground where the groundwater can move quickly and over...

Problem - The major hydrogeologic units of Long Island, New York, have been delineated as part of the islandwide mapping effort of Smolensky, Buxton, and Shernoff that was published in 1989 as U.S. Geological Survey (USGS) Hydrologic Atlas (HA) 709. Concern about local details in the hydrogeologic framework that may not be represented in HA-709 has led the USGS, in cooperation with the U.S. Environmental Protection Agency (EPA), to assess the hydrogeology of the Long Island area so ground-water-flow modeling planned by EPA can more fully reflect local hydrogeologic conditions. Objectives - The primary objective of this project is to construct geographic information system (GIS) datasets of the altitudes of the...
Background The North Atlantic Coastal Plain (NACP) covers a land area of approximately 34,000 mi 2 along the eastern seaboard of the United States from Long Island, N.Y., southward to the northern portion of North Carolina. This area is underlain by a thick wedge of sedimentary deposits that form a complex groundwater system in which the sands and gravels function as confined aquifers, and the silts and clays function as confining units. These confined aquifers of the NACP constitute a major source of water for public and domestic supply for the nearly 27 million people living in the region, as well as being important source of water for industrial and agricultural purposes. Increases in population and changes...

Problem The discharge of freshwater and associated loading of nutrients and other dissolved constituents from the Long Island aquifer system to surrounding estuaries and their tributaries are increasingly recognized as critical factors in the health of these ecosystems. However, further work is needed to scientifically characterize these factors and present them to the public in an appropriate manner. Many organizations have undertaken assessments of this discharge and loading for discrete groundwater source areas and (or) receiving surface waters, applying a variety of techniques and assumptions. In part, this is because there is no delineation of recharge areas to the island’s groundwater-fed streams and estuaries...

INTRODUCTION Naturally occurring methane has been noted at some locations in the upper Devonian shale bedrock and in overlying glacial deposits in parts of Broome, Tioga, and Chemung Counties in south-central New York State (Williams, 2010). Systematic sampling of water wells for dissolved methane is needed to determine if the topographic and hydrogeologic setting of a well is related to methane occurrence. Objective and Study Area - The objective of this study is to characterize the natural occurrence of dissolved methane gas in groundwater from water wells within four different topographic and hydrogeologic settings (upland and major valley areas where bedrock is confined or unconfined by glacial deposits)....

Hydrogeologic characterization of the basal sand and gravel aquifer in the Hoosic River valley in Hoosick Falls, New York is important for determination of sources, extent, and future migration of PFOA groundwater contamination; evaluation of potential remedial actions; and appraisal of alternative groundwater supplies. Variations in the current pumping stresses and a planned 72-hour aquifer test provide an opportunity to characterize hydraulic connections in the basal sand and gravel aquifer through continuous monitoring of groundwater levels in selected wells.

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...

Problem - Roof collapses in the Retsof salt mine near Geneseo N.Y. in March and April of 1994 propagated upward through overlying bedrock, forming a 600-ft-long rubble zone or chimney that connected the mine to a glacial aquifer system and created sinkholes at land surface. Fresh water from the glacial aquifers flowed downward into the mine until the mine was completely flooded in January 1996. The mine opening is predicted to slowly close over a period of several hundred years, with most of the subsidence occurring before 2070. As the mine opening closes, about 40 percent of the brine will be displaced from the mine and migrate upward through the rubble chimney. Continuing monitoring of chloride concentrations...

Problem Onondaga Lake has been identified as one of the nation's most contaminated lakes as a result of discharges from industrial, sewage, and stormwater sources, and the lake received priority cleanup status under the National Water Resources Development Act of 1990. Although remediation of polluted surface-water discharges is planned, the migration of poor quality (saline) ground water into the lake also affects the quality of lake water and may impair the remediation plans. Anthropogenic contamination has been identified at several sites near the lakeshore, including the former Allied Signal soda ash production facility and a former petroleum storage facility. Saline discharges from the Allied Signal waste...

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....

Background: Moreau Lake is located within Moreau Lake State Park, a 4,100 acre park divided by the Hudson River in northern Saratoga and southern Warren Counties of upstate New York. Moreau Lake has a surface area of 128 acres, a watershed of 469 acres, and 3.6 miles of shoreline. The lake has a “normal” mean depth of 32 feet and a maximum depth of 50 feet. An outlet control structure at the south end of the lake controls surface water outflow and protects adjacent property within the floodplain of Moreau Lake. The lake is considered a kettle lake and as such is surrounded by ice-contact sand and gravel (NY State Parks, 2006). Moreau Lake is a recreational water body used by the public for swimming, fishing,...

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....

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...
