The U-tube: A novel system for acquiring borehole fluid samples from a deep geologic CO2 sequestration experiment
Barry M. Freifeild, Robert C. Trautz, Yousif K. Kharaka, Tommy J. Phelps, Larry R. Myer, Susan D. Hovorka, Daniel J. Collins
2005, Journal of Geophysical Research Solid Earth (110)
A novel system has been deployed to obtain geochemical samples of water and gas, at in situ pressure, during a geologic CO2 sequestration experiment conducted in the Frio brine aquifer in Liberty County, Texas. Project goals required high-frequency recovery of representative and uncontaminated aliquots of a rapidly changing two-phase fluid...
Effects of emission reductions at the Hayden powerplant on precipitation, snowpack, and surface-water chemistry in the Mount Zirkel Wilderness Area, Colorado, 1995-2003
M. Alisa Mast, Donald H. Campbell, George P. Ingersoll
2005, Scientific Investigations Report 2005-5167
Precipitation, snowpack, and surface-water samples collected during 1995-2003 were analyzed to evaluate the effects of emission reductions at the Hayden powerplant on water chemistry in the Mount Zirkel Wilderness Area. The Hayden powerplant, one of two large coal-fired powerplants in the Yampa Valley, was retrofitted with control systems during...
Southern California landslides-an overview
Water Resources Division, U.S. Geological Survey
2005, Fact Sheet 2005-3107
Southern California lies astride a major tectonic plate boundary defined by the San Andreas Fault and numerous related faults that are spread across a broad region. This dynamic tectonic environment has created a spectacular landscape of rugged mountains and steep-walled valleys that compose much of the region’s scenic beauty. Unfortunately,...
Characterization of surface-water quality in the S-Line Canal and potential geochemical reactions from storage of surface water in the Basalt aquifer near Fallon, Nevada
Alan H. Welch, Douglas K. Maurer, Michael S. Lico, John K. McCormack
2005, Scientific Investigations Report 2005-5102
The Fallon basalt aquifer serves as the sole source of municipal water supply for the Lahontan Valley in west-central Nevada. Principal users include the City of Fallon, Naval Air Station Fallon, and the Fallon Paiute-Shoshone Tribe. Pumpage from the aquifer increased from about 1,700 acre-feet per year in the early...
Historical perspective of statewide streamflows during the 2002 and 1977 droughts in Colorado
Gerhard Kuhn
2005, Scientific Investigations Report 2005-5174
Since 1890, Colorado has experienced a number of widespread drought periods; the most recent statewide drought began during 1999 and includes 2002, a year characterized by precipitation, snowpack accumulation, and streamflows that were much lower than normal. Because the drought of 2002 had a substantial effect on streamflows in Colorado,...
Historical subsidence and wetland loss in the Mississippi delta plain
Robert A. Morton, Julie Bernier, John A. Barras, Nicholas F. Ferina
2005, Conference Paper, Gulf Coast Association of Geological Societies Transactions
Five representative areas of the Mississippi River delta plain were investigated using remote images, marsh elevations, water depths, sediment cores, and radiocarbon dates to estimate the timing, magnitudes, and relative rates of marsh erosion and land subsidence at geological and historical time scales. In the Terrebonne-Lafourche region of rapid interior-wetland...
Water use for irrigation in Michigan, 2001
Michele L. Morenz, Ron L. Van Til, Carol L. Luukkonen
2005, Fact Sheet 2005-3079
Each year, water-use data for Michigan are compiled or estimated by the Michigan Department of Environmental Quality (MDEQ), working in cooperation with the U. S. Geological Survey (USGS). The resulting information provides a category-by-category profile of over 4,200 facilities throughout the State. The data are reported in the Michigan Water...
Influence of geologic setting on ground-water availability in the Lawrenceville area, Gwinnett County, Georgia
Lester J. Williams, Randy L. Kath, Thomas J. Crawford, Melinda J. Chapman
2005, Scientific Investigations Report 2005-5136
Obtaining large quantities of ground water needed for municipal and industrial supply in the Piedmont and Blue Ridge physiographic provinces can be challenging because of the complex geology and the typically low primary permeability of igneous and metamorphic rocks. Areas of enhanced secondary permeability in the bedrock do occur, however,...
Estimation of constituent concentrations, densities, loads, and yields in lower Kansas River, northeast Kansas, using regression models and continuous water-quality monitoring, January 2000 through December 2003
Teresa J. Rasmussen, Andrew C. Ziegler, Patrick P. Rasmussen
2005, Scientific Investigations Report 2005-5165
The lower Kansas River is an important source of drinking water for hundreds of thousands of people in northeast Kansas. Constituents of concern identified by the Kansas Department of Health and Environment (KDHE) for streams in the lower Kansas River Basin include sulfate, chloride, nutrients, atrazine, bacteria, and sediment. Real-time...
Hydrology and simulation of ground-water flow in Cedar Valley, Iron County, Utah
Lynette E. Brooks, James L. Mason
2005, Scientific Investigations Report 2005-5170
Cedar Valley, located in the eastern part of Iron County in southwestern Utah, is experiencing rapid population growth. Cedar Valley traditionally has supported agriculture, but the growing population needs a larger share of the available water resources. Water withdrawn from the unconsolidated basin fill is the primary source for public...
Assessment of shallow ground-water quality in recently urbanized areas of Sacramento, California, 1998
Jennifer L. Shelton
2005, Scientific Investigations Report 2005-5148
Evidence for anthropogenic impact on shallow ground-water quality beneath recently developed urban areas of Sacramento, California, has been observed in the sampling results from 19 monitoring wells in 1998. Eight volatile organic compounds (VOCs), four pesticides, and one pesticide transformation product were detected in low concentrations, and nitrate, as nitrogen,...

Donald H. Wilkison, Daniel J. Armstrong, Rebecca E. Brown, Barry C. Poulton, Jeffrey D. Cahill, Steven D. Zaugg
2005, Data Series 127
This report presents water-quality and biologic data collected in the Blue River Basin, metropolitan Kansas City, Missouri and Kansas, from October 2000 to October 2004. Data were collected in cooperation with the city of Kansas City, Missouri, Water Services Department as part of an ongoing study designed to characterize long-term...
Sediment studies in the Assabet River, central Massachusetts, 2003
Marc J. Zimmerman, Jason R. Sorenson
2005, Scientific Investigations Report 2005-5131
From its headwaters in Westborough, Massachusetts, to its confluence with the Sudbury River, the 53-kilometer-long Assabet River passes through a series of small towns and mixed land-use areas. Along the way, wastewater-treatment plants release nutrient-rich effluents that contribute to the eutrophic state of this waterway. This condition is most obvious...

This study, completed by the U.S. Geological Survey (USGS) in cooperation with the Pennsylvania Department of Conservation and Natural Resources, Bureau of Topographic and Geologic Survey (T&GS), provides estimates of ground-water recharge for watersheds throughout Pennsylvania computed by use of two automated streamflow-hydrograph-analysis methods--PART and RORA. The PART computer program...
Field tests of nylon-screen diffusion samplers and pushpoint samplers for detection of metals in sediment pore water, Ashland and Clinton, Massachusetts, 2003
Marc J. Zimmerman, Don A. Vroblesky, Kimberly W. Campo, Andrew J. Massey, Walter Scheible
2005, Scientific Investigations Report 2005-5155
Efficient and economical screening methods are needed to detect and to determine the approximate concentrations of potentially toxic trace-element metals in shallow groundwater- discharge areas (pore water) where the metals may pose threats to aquatic organisms; such areas are likely to be near hazardous-waste sites. Pushpoint and nylon-screen diffusion samplers...
Geochemical assessment of metals and dioxin in sediment from the San Carlos Reservoir and the Gila, San Carlos, and San Francisco Rivers, Arizona
Stan E. Church, LaDonna M. Choate, Marci E. Marot, David L. Fey, Monique Adams, Paul H. Briggs, Zoe Ann Brown
2005, Scientific Investigations Report 2005-5086
In October 2004, we sampled stream-bed sediment, terrace sediment, and sediment from the San Carlos Reservoir to determine the spatial and chronological variation of six potentially toxic metals-Cu, Pb, Zn, Cd, As, and Hg. Water levels in the San Carlos Reservoir were at a 20-year low at an elevation of...
