Ground-water hydrology of the Willamette basin, Oregon
Terrence D. Conlon, Karl C. Wozniak, Douglas Woodcock, Nora B. Herrera, Bruce J. Fisher, David S. Morgan, Karl K. Lee, Stephen R. Hinkle
2005, Scientific Investigations Report 2005-5168
The Willamette Basin encompasses a drainage of 12,000 square miles and is home to approximately 70 percent of Oregon's population. Agriculture and population are concentrated in the lowland, a broad, relatively flat area between the Coast and Cascade Ranges. Annual rainfall is high, with about 80 percent of precipitation falling...
California GAMA program: ground-water quality data in the San Diego drainages hydrogeologic province, California, 2004
Michael T. Wright, Kenneth Belitz, Carmen A. Burton
2005, Data Series 129
Because of concerns over ground-water quality, the California State Water Resources Control Board (SWRCB), in collaboration with the U.S. Geological Survey and Lawrence Livermore National Laboratory, has implemented the Ground-Water Ambient Monitoring and Assessment (GAMA) Program. A primary objective of the program is to provide a current assessment of ground-water...
Streamflow, water-quality, and biological data for three tributaries to Lake Houston near Houston, Texas, 2002-04
Jeffery W. East, Debra A. Sneck-Fahrer
2005, Data Series 142
During 2002-04 the U.S. Geological Survey, in cooperation with the Houston-Galveston Area Council and the Texas Commission on Environmental Quality, conducted a systematic monitoring study on Lake Creek, Peach Creek, and Caney Creek near Houston, Texas, to assess the current water-quality and biological conditions in the three tributaries to Lake...
Compilation of geologic, hydrologic, and ground-water flow modeling information for the Spokane Valley-Rathdrum Prairie aquifer, Spokane County, Washington, and Bonner and Kootenai Counties, Idaho
Sue C. Kahle, Rodney R. Caldwell, James R. Bartolino
2005, Scientific Investigations Report 2005-5227
The U.S. Geological Survey, in cooperation with the Idaho Department of Water Resources and Washington Department of Ecology compiled and described geologic, hydrologic, and ground-water flow modeling information about the Spokane Valley-Rathdrum Prairie (SVRP) aquifer in northern Idaho and northeastern Washington. Descriptions of the hydrogeologic framework, water-budget components, ground- and...
Volatile organic compound matrix spike recoveries for ground- and surface-water samples, 1997-2001
Barbara L. Rowe, Gregory C. Delzer, David A. Bender, John S. Zogorski
2005, Scientific Investigations Report 2005-5225
The U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program used field matrix spikes (FMSs), field matrix spike replicates (FMSRs), laboratory matrix spikes (LMSs), and laboratory reagent spikes (LRSs), in part, to assess the quality of volatile organic compound (VOC) data from water samples collected and analyzed in more than 50...
Water availability for the Western United States--Key scientific challenges
Mark Theodore Anderson, Lloyd H. Woosley Jr.
2005, Circular 1261
In the Western United States, the availability of water has become a serious concern for many communities and rural areas. Near population centers, surface-water supplies are fully appropriated, and many communities are dependent upon ground water drawn from storage, which is an unsustainable strategy. Water of acceptable quality is increasingly...
Occurrence of selected pharmaceutical and non-pharmaceutical compounds, and stable hydrogen and oxygen isotope ratios in a riverbank filtration study, Platte River, Nebraska, 2002 to 2005, Volume 2
J. R. Vogel, L. B. Barber, E. T. Furlong, T.B. Coplen, Ingrid M. Verstraeten, M. T. Meyer
2005, Data Series 141
This document is the second volume of a data series report that describes the data collected during a study conducted during 2001 through 2005 by the U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency and the City of Lincoln, at an established riverbank-filtration well field with horizontal...
Arsenic in ground water in selected parts of southwestern Ohio, 2002-03
Mary Ann Thomas, Thomas L. Schumann, Bruce A. Pletsch
2005, Scientific Investigations Report 2005-5138
Arsenic concentrations were measured in 57 domestic wells in Preble, Miami, and Shelby Counties, in southwestern Ohio. The median arsenic concentration was 7.1 ?g/L (micrograms per liter), and the maximum was 67.6 ?g/L. Thirty-seven percent of samples had arsenic concentrations greater than the U.S. Environmental Protection Agency drinking-water standard of...
Radiochemical sampling and analysis of shallow ground water and sediment at the BOMARC Missile Facility, east-central New Jersey, 1999-2000
Zoltan Szabo, Otto S. Zapecza, Jeannette H. Oden, Donald E. Rice
2005, Scientific Investigations Report 2005-5062
A field sampling experiment was designed using low-flow purging with a portable pump and sample-collection equipment for the collection of water and sediment samples from observation wells screened in the Kirkwood-Cohansey aquifer system to determine radionuclide or trace-element concentrations for various size fractions. Selected chemical and physical characteristics were determined...
187Os/188Os And Highly Siderophile Element Systematics Of Apollo 17 Aphanitic Melt Rocks
I.S. Puchtel, R. J. Walker, O.B. James
2005, Conference Paper
Generally chondritic relative abundances and high absolute abundances of the highly siderophile elements (HSE: Ru, Rh, Pd, Re, Os, Ir, Pt, Au) in Earth's upper mantle provide strong evidence that these elements were added to the Earth following the last major interaction between its metallic core and silicate fraction. So...
