Water-quality assessment of the Rio Grande Valley, Colorado, New Mexico and Texas: Ground-water quality in the Rio Grande flood plain, Cochiti Lake, New Mexico, to El Paso, Texas, 1995
L. M. Bexfield, S. K. Anderholm
1997, Water-Resources Investigations Report 96-4249
From March to May of 1995, water samples were collected from 30 wells located in the flood plain of the Rio Grande between Cochiti Lake, New Mexico, and El Paso, Texas. These samples were analyzed for a broad host of constituents, including field parameters, major constituents, nutrients, dissolved organic carbon,...
Reconnaissance of 17 beta-estradiol, 11-ketotestosterone, vitellogenin, and gonad histopathology in common carp of United States streams; potential for contaminant-induced endocrine disruption
Steven L. Goodbred, Robert J. Gilliom, Timothy S. Gross, Nancy P. Denslow, Wade B. Bryant, Trenton R. Schoeb
1997, Open-File Report 96-627
A reconnaissance of sex steroid hormones and other biomarkers in common carp was used to assess whether endocrine disruption may be occurring in fish in United States streams, to evaluate relations between endocrine disruption and contaminant levels, and to determine requirements for further studies. 17?-estradiol, 11-ketotestosterone, vitellogenin, and gonadal histopathology...
Volcano hazards in the Mount Hood region, Oregon
W. E. Scott, T.C. Pierson, S. P. Schilling, J. E. Costa, C. A. Gardner, J.W. Vallance, J. J. Major
1997, Open-File Report 97-89
Mount Hood is a potentially active volcano close to rapidly growing communities and recreation areas. The most likely widespread and hazardous consequence of a future eruption will be for lahars (rapidly moving mudflows) to sweep down the entire length of the Sandy (including the Zigzag) and White River valleys. Lahars...
Hydrogeologic facies characterization of an alluvial fan near Fresno, California, using geophysical techniques
Karen R. Burow, G.S. Weissmann, R. D. Miller, Gary Placzek
1997, Open-File Report 97-46
DBCP (1,2-dibromo-3-chloropropane) contamination in the sole source aquifer near Fresno, California, has significantly affected drinking-water supplies. Borehole and surface geophysical data were integrated with borehole textural data to characterize the Kings River alluvial fan sediments and to provide a framework for computer modeling of pesticide transport in ground water. Primary...

1997, Open-File Report 97-22
The Minnesota Management Systems Evaluation Area (MSEA) project was part of a multi-scale, inter-agency initiative to evaluate the effects of agricultural management systems on water quality in the midwest corn belt. The research area was located in the Anoka Sand Plain about 5 kilometers southwest of Princeton, Minnesota. The ground-water-quality...

Water-quality trends in the Rio Grande/Rio Bravo Basin using sediment cores from reservoirs
Peter C. Van Metre, B.J. Mahler, Edward C. Callender
1997, Fact Sheet 221-96
Water-quality trends reflect the relation between water quality and human activities, chronicling changes in concentrations of environmental contaminants, introduction of new contaminants, and successful efforts in environmental pollution remediation. Historical data available for analyzing trends often have severe limitations, from questionable accuracy to unknown sampling and analytic methodologies. Where data...

1997, Water-Resources Investigations Report 96-4313
A total of 229 ground-water samples were collected from 215 sites as part of the Ozark Plateaus study unit of the National Water-Quality Assessment Program. These samples were collected from 1993 through 1995 using a network of springs and wells with three scale-dependent components. The first component, the study-unit survey,...
Climate and ocean dynamics and the lead isotopic records in Pacific ferromanganese crusts
John N. Christensen, Alex N. Halliday, Linda V. Godfrey, James R. Hein, David K. Rea
1997, Science (277) 913-918
As hydrogenous iron-manganese crusts grow, at rates of millimeters per million years, they record changes in the lead isotopic composition of ambient seawater. Time-resolved lead isotopic data for cut slabs of two central Pacific iron-manganese crusts that have been growing since about 50 million years ago were measured in situ...
