Problem The Tully Valley, located in southern Onondaga County has been the source of sediment and brackish water discharge to Onondaga Creek, a tributary to the Seneca and Oswego Rivers and eventually Lake Ontario. Information on the origin of the Tully Valley mudboils, their persistence, and the possible extent of their migration within the Tully Valley is needed to mitigate or remediate (1)the discharge of turbid water and fine-grained sediment from the mudboils, (2) land-surface subsidence caused by the removal of sediment from below the land surface, and (3) degradation of Onondaga Creek by turbidity, fine-sediment deposition, and chloride loading. Objectives To define the glacial stratigraphy and hydraulic-head...

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.

The Pepacton watershed is an integral part of New York City's public-water supply system. Most of the watershed is within Delaware County with headwaters of some of its eastern tributary streams originating in Greene and Ulster Counties. Land use varies from dairy farms in the northern portion of the watershed to extensive forested areas in the south with small rural communities interspersed throughout the watershed. Sound management of the water resources in the region necessitates development of hydrologic data networks that will document current water-quality conditions in relation to watershed characteristics such as land use. Ground-water discharge to streams accounts for most of the water reaching the New...

The United States Geological Survey (USGS), in cooperation with the New York State Department of Environmental Conservation (NYSDEC), monitors a network of observation wells throughout New York to provide current information on the effect of climatic conditions on groundwater levels. At present (2015), there are 95 observation wells in unconsolidated and bedrock aquifers, all of which are equipped with telemetry for near real time data transmission. Daily groundwater levels and hydrographs for each well site are available online in the National Water Information System (NWIS). In addition, monthly assessments of ground-water conditions, based on frequency statistical analysis of the monitoring data, are provided...
