Significant changes in nitrogen loads to Jamaica Bay have likely occurred with progressive improvements to Water Pollution Control Plants (WCWPs) that discharge into the Bay. Data available from the New York City Department of Environmental Protection and others will be used to determine loads from WPCPs, combined sewer overflows, and the atmosphere. Selected wells within the USGS water quality database, including those near the landfills that are immediately adjacent to Jamaica Bay, will be used to determine concentrations of nutrients in shallow ground water that enter the bay from ground water seepage. To facilitate evaluation of ground water loads, an existing USGS Finite element model that simulates sub...

This dataset includes the magnetotelluric (MT) sounding data collected in 2005 along an east-west profile north of Wells, Nevada. It is important to know whether major mining districts in the Northern Nevada Gold Province are underlain by rocks of the Archean Wyoming craton, which are known to contain orogenic gold deposits, or by accreted rocks of the Paleoproterozoic Mojave province. It is also important to know the location and orientation of the Archean/Proterozoic suture zone between these provinces as well as major basement structures within these terranes because they may influence subsequent patterns of sedimentation, deformation, magmatism, and hydrothermal activity. This study was funded by the U.S. Geological...
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...
Delineation of the Freshwater-Saltwater Interface at Selected Public-Supply Wells Using Advanced Surface and Borehole Geophysical Techniques, in Eastern Suffolk County, New York
The combination of a complex hydrogeologic framework, narrow land masses surrounded by saltwater, and extensive ground-water public-supply pumpage has produced localized areas of elevated chloride concentrations in ground water. This project uses advanced surface and borehole geophysical methods to determine the extent of saltwater intrusion and road-salt plumes at selected sites in eastern Suffolk County, Long Island, NY. Two-dimensional resistivity sections have been integrated with borehole geophysical logs and water-quality data to produce cross-sections of road-salt plumes. Borehole geophysical logs are collected twice a year to determine variations in chloride concentration and thicknesses of intrusive...

Shapefile: Potentiometric wells for the Upper Floridan aquifer in Florida and parts of Georgia, South Carolina, and Alabama, May-June 2010 – Updated
Water-level measurements of wells were taken in the Upper Floridan aquifer between the dates of May 2 and June 23, 2010. A GIS shapefile of these water-level measurements was constructed and released as part of a prior USGS publication (Kinnaman and Dixon, 2011). This ArcGIS layer was updated in August 2014 to include salinity-based density corrections to water levels in those areas of south Florida where water in the subject aquifer is not fresh. The density corrections to water levels result in the portrayal of the “equivalent freshwater head” values in brackish and saline areas of the Upper Floridan aquifer where water quality data were available.
A complete set of wells associated with oil, natural gas, and coal bed natural gas development in the western states as of June 2004. This is a static dataset even though liquid energy development is a highly dynamic endeavor. Because these well location datasets are generally housed and managed by various state-based agencies (typically the state Oil and Gas Conservation Commissions) a uniform, spatially precise coverage for the western United States has not been available to date. This layer consolidates the best available well location data from ND, SD, MT, WY, CO, NM, UT, AZ, OR, and CA (ID and WA do not report any liquid energy development) and standardizes the attributites. While static as of June 2004 the...

Geohydrology of the Valley-Fill Aquifer in Upper Buttermilk Creek/Danby Creek Valleys, Town of Danby, Tompkins County, New York
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....

The United States and Mexico share waters in a number of hydrological basins and aquifers that cross the International Boundary. Both the United States and Mexico recognize that, in a region of scarce water and expanding populations, better...
