Geohydrology of the Valley‐fill Aquifer in the Lower Fall Creek Valley, Town of Dryden, Tompkins County, New York

PROBLEM The valley‐fill aquifer in the lower Fall Creek valley (designated as aquifer 4, fig. 1), within the Towns of Dryden and Groton, was mapped by Miller (2000) and identified as one of 17 unconsolidated aquifers in Tompkins County that need to be studied in more detail. The east end of the valley (near the Tompkins and Cortland County border) is on the backside of a large morainal plug,...

DETAILED AQUIFER MAPPING OF THE SPRINGVILLE, N.Y. AREA Erie, Cattaraugus, and Wyoming Counties, New York

Introduction Public-water systems at Springville and Yorkshire/Delavan, N.Y. along Cattaraugus Creek draw from local groundwater resources and serve about 5,500 people (U.S. EPA SDWIS database). The remainder of the population obtains water from domestic wells, many of them completed in glacial aquifers. A Cattaraugus Creek tributary valley (Buttermilk Creek) to the south is the site of the...

Determination of Sources of Water to the Tully Valley Mudboils

Background and Problem Tully Valley is part of the Onondaga Trough, which extends from the Valley Heads Moraine in the south to Onondaga Lake in the north near Syracuse, New York (fig. 1). The Onondaga Trough is filled with a complex sequence of glacial and post-glacial sediments that overlie Devonian carbonate rock and shale and Silurian shale and salt (fig.2). Mudboils, volcano-like cone...

Groundwater Sustainability of the Long Island Aquifer System

Groundwater sustainability can be best defined as the development and use of groundwater in a manner that can be maintained for an indefinite time without causing unacceptable environmental or socioeconomic consequences. Informed management of the Long Island aquifer system can help ensure a regionally sustainable groundwater resource. The USGS and New York State Department of Environmental...

Saltwater-Interface Mapping - Long Island, New York

Home

Saltwater intrusion is the most common type of water-quality degradation in coastal-plain aquifers. In coastal areas, the hydraulic head under predevelopment (nonpumping) conditions is higher on land than in the surrounding...

The Use of Solute-transport Methods to Estimate Time-varying Nitrogen Loading Rates to the Peconic Estuary Resulting from Wastewater and Fertilizer Inputs to Groundwater in Suffolk County, New York (Peconic Solute Transport)

Problem The Peconic Estuary of eastern Long Island, New York, is undergoing development as the region transitions from a rural area dependent on agriculture and tourism to a suburban one with a larger year-round population. The glacial and coastal-plain sediments underlying Long Island comprise a sole-source aquifer system that supplies the region’s communities with potable water. The area...
