Natural Methane Occurrence in Water Wells of South-Central New York State- Evaluation of Topographic Position and Hydrogeologic Setting 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)....

The existing science being used to inform decisions on remediation is biased toward activities are necessarily focused on the immediate aftermath of storms An assessment of the sources of contaminants that may have been introduced from inundation is needed to provide a context with which the Tribal community can better understand how to prioritize and manage the sources and minimize risk.

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 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...

Recent hydrogeologic mapping in Manhasset Neck indicates significant glacial erosion of the Magothy aquifer, Raritan Clay, and Lloyd aquifer, and several gaps in the confining units that overlie the North Shore and Lloyd aquifers. Five areas of salt-water intrusion have been delineated, two of which are considered active. Several public-supply wells on the Manhasset Neck Peninsula have been shut down in the past as a result of saltwater intrusion....

The Tug Hill aquifer can be divided into three parts (northern, central, and southern) based on geohydrological setting, depositional history, and type of glacial deposits (fig. 1). In this study, the name “Tug Hill glacial aquifer” refers only to the 29-mi-long northern and central parts of the Tug Hill aquifer. (The southern part was not included in this investigation.) For this study, the division between the northern and central parts of the aquifer was placed...

The objective of the 305(b) Ambient Groundwater Quality Monitoring project is to quantify and report on ambient groundwater quality from bedrock and glacial-drift aquifers in upstate New York. An ongoing cooperative project between the U.S. Geological Survey (USGS) and New York State Department of Environmental Conservation (NYSDEC), this study supports NYSDEC’s responsibilities under Section 305(b) of the Clean Water Act Amendments of 1977. The project began in 2002 with a pilot study in the Mohawk...

The onsite disposal of wastewater within the Patchogue River basin - a riverine estuary that discharges into Great South Bay, Suffolk County, Long Island, NY - has adversely affected water quality and aquatic habitats within both the tidal and non-tidal portions of the river. Of particular concern are increased loads of nutrients (nitrate, nitrite, ammonia, and phosphorus) to the shallow groundwater system which...

Previous USGS studies in this area indicate the northern part of Nassau County has a complex hydrogeologic framework (Stumm and others, 2004). A previously mapped buried glacial valley may extend and be present at this location. If such a buried valley exists, all Cretaceous age deposits (Magothy aquifer, Raritan clay, and Lloyd aquifer) may have been eroded and Pleistocene-aged deposits including the North Shore aquifer...

Unfortunately, comprehensive data on the quantity and quality of the Counties' water resources are not available to make an accurate assessment. In order to evaluate the availability and suitability of these resources, representative and timely data on the ground-water and surface-water resources of these three Counties are needed.
