Problem The Village of Dryden, rural homeowners, farms, and businesses in the Virgil Creek Valley tap several confined sand and gravel aquifers in the Virgil Creek valley in the town of Dryden . The valley contains a large moraine with complex stratigraphy consisting of continuous and discontinuous layers of till, lake deposits, and glaciofluvial sand and gravel. Sand and gravel units form the aquifers in the valley-fill deposits. There are at least three extensive confined aquifer units at various depths. However, little is known about (1) the location of recharge and discharge areas, (2) direction of groundwater flow, (3) extent of hydraulic connection between aquifer units, and (4) extent of surface- and ground-water...

Title IV has been successful in reducing emissions of SO2 and NOx from power generation to the levels set by Congress. In fact, by 2009, SO2 emissions from power plants were already 3.25 million tons lower than the final 2010 cap level of 8.95 million tons, and NOx emissions were 6.1 million tons less than the projected level in 2000 without the ARP, or more than triple the Title IV NOx emission-reduction objective. As a result of these emission reductions, air quality has improved, providing significant human health benefits, and acid deposition has decreased to the extent that some acid-sensitive areas are beginning to show signs of recovery. Current emission reductions and the passage of time, which is needed...
The USGS uses an integrated geologic, hydrologic, and geophysical approach to characterize the unconsolidated and bedrock aquifers in the State. Hydrogeologic framework characterization is the backbone of most groundwater-related studies, including those involving aquifer mapping, saltwater-intrusion delineation, groundwater flow and transport modeling, geologic-hazards evaluation, water-tunnel construction and repair, geothermal assessments, and groundwater-quality sampling. The NYWSC uses state-of-the-art geophysical equipment for training and methods development for geophysics that include borehole-wall imagers, gamma spectral, induction, and full waveform sonic tools, and electromagnetic and heat-pulse flowmeters....

The NYWSC has a laboratory for analysis of soils and water samples collected by USGS projects throughout the Northeast and provides accurate measurements of soil water, nonagricultural soils, stream water, and lake water that can be adapted to the specific needs of each study. The laboratory’s quality-assurance program is based on internal and interlaboratory quality-assurance samples and quality-control procedures that were developed to ensure proper sample collection, processing, and analysis. The laboratory includes many state-of-the-art instruments, including an ion chromatograph, an inductively coupled plasma spectrophotometer, a dissolved carbon analyzer, three flow-injection analyzers, a carbon-nitrogen analyzer...

The U.S. Geological Survey (USGS) is providing online maps of water-table and potentiometric-surface altitude in the upper glacial, Magothy, Jameco, Lloyd, and North Shore aquifers on Long Island, New York, April-May 2013. Also provided here, is a Depth-to-Water map for Long Island, NY, April-May 2013. USGS serves these maps and geospatial data as REST Open Map Services (as well as HTTP, JSON, KML, and shapefile), so end-users can use the maps and data on mobile and web clients. A companion report, U.S. Geological Survey Scientific Investigations Map 3326 (Como and others, 2015; http://dx.doi.org/10.3133/sim3326) further describes data collection and map preparation and presents 68x22 in.

The NYWSC carries out multidisciplinary science activities across the State’s diverse coastal waters and landscapes on the Atlantic Ocean and the Great Lakes, including the many interconnected waterways, the barrier beaches that form and erode continually, the open waterways that are prone to the effects of major storms and hurricanes, and upland surface-water and groundwater source areas. These areas are also some of the most productive ecosystems in the State and host most of the population and economic development of the State. As a result, the interplay of environmental- and human-health concerns is a prominent thread that connects much of the coastal science activities of the USGS and involves cooperation not...

Problem - Increasing development within the Shenandoah Valley in recent years has placed additional demands on the region’s water resources. The sedimentary rocks in the Valley have been compressed and folded by tectonic forces to form a 5-km deep basin. Ground water, a principal component of the available water supply, flows through fractures in the sedimentary and crystalline rocks that underlie the Valley. Bedding fractures in the rocks are angled downward along the dip of the folds, allowing ground water to penetrate deeply below land surface—fresh water is obtained from wells over 800 ft deep in the Valley. Objectives - Develop a ground-water-flow model to simulate movement of ground water and estimate the...

Purpose and Scope The Natural Resources Department of the Bad River Band of Lake Superior Chippewa, Odanah, Wisconsin has requested assistance with compiling existing mercury (Hg) concentration data from measurements in a variety of environmental media in an effort to evaluate risks to ecosystem and human health and to identify key data gaps that could be addressed through future sampling. These data include Hg concentrations in fish, frogs, otters, birds, wild rice, the atmosphere, surface water, and sediment. The purpose of this proposed study is to compile existing Hg data collected by the Bad River Band of Lake Superior Chippewa, evaluate the potential risks to humans and to local ecosystems, and to recommend...
Ecological assessments are a central focus of multidisciplinary projects and programs managed by the NYWSC and managed in cooperation with the water and soil chemistry laboratory as well as other Federal, State, county, and city agencies, academia, and nongovernmental organizations in New York and nationwide. The NYWSC studies the condition of aquatic communities to assess the effects of various manmade and natural stressors and of resource management practices on the aquatic ecosystems and environments in the State and nationwide and in cooperation with a wide array of partners and monitors climate change indicators to identify trends and data gaps for indicators of climate and habitat change. Specific studies...

Problem - Several supply wells in Oswego County were evaluated by the USGS in 1999 by using stable oxygen and hydrogen isotopes and chlorofluorocarbon (CFC) age dating techniques. For two municipal well sites (the Villages of Sandy Creek and Lacona, and the Village of Pulaski) that tap a shallow, unconfined aquifer (typically 20-50 ft thick) there were significant discrepancies between ground-water recharge ages determined by chemical data and those determined by ground-water-flow models developed by independent studies. The significant discrepancies between the times of travel of ground water as determined by numerical ground-water-flow modeling and geochemical dating techniques in Oswego County need to be understood...

Background The Shinnecock Nation is located on the south fork of eastern Long Island adjacent to the town of Southampton to the east, and the hamlet of Shinnecock Hills to the west, in Suffolk County, NY. Shinnecock Nation tribal lands encompass approximately 1.2 square miles and are bounded to the east and west by tidal creeks, and to the south by Shinnecock Bay. The Shinnecock Nation has a population of 662 residents who live in 256 housing units (U.S. Census, 2016). The Shinnecock Nation became the 565th federally recognized Tribe by the United States government in October 2010. (Shinnecock Nation, 2014). Shinnecock Nation tribal lands are situated in a coastal environment where bay and wetland health are...
