Pesticide amounts are small in streams in the Red River of the North Basin, 1993-94
L. H. Tornes, Mark E. Brigham
1995, Open-File Report 95-283
Pesticides are used extensively in the largely agricultural Red River of the North (Red River) Basin, but, unlike many other agricultural basins, only small amounts are routinely detected in samples from streams in the basin. The pesticides detected comprise less than 2 percent of the amount applied and usually are...
Data on ground-water levels and ground-water/surface-water relations in the Great Miami River and Little Miami River valleys, southwestern Ohio
William P. Yost
1995, Open-File Report 95-357
Hydrogeologic data were collected in September, October, and November 1993 to define the ground-water levels and the ground-water/surface-water relations in the vicinity of Dayton, Ohio. In this report, water levels are listed for 678 wells completed in sand and gravel. Data from 101 streamflow measurements made at selected sites along...
Physical characteristics of stream subbasins in the upper Minnesota River basin, west-central Minnesota, northeastern South Dakota and southeastern North Dakota
Chris Sanocki
1995, Open-File Report 95-162
Data that describe the physical characteristics of stream subbasins upstream from selected points on streams in the Upper Minnesota River Basin, located in west-central Minnesota, north-eastern South Dakota, and southeastern North Dakota, are presented in this report. The physical characteristics are the drainage area of the subbasin, the percentage area...
U.S. Geological Survey activities in New Mexico 1995
Russell K. Livingston
1995, Open-File Report 95-314
The report provides an overview of the USGS in New Mexico, including activities of the Water Resources, Geologic, and National Mapping Divisions. Some USGS projects address hydrologic and geologic hazards, such as flood discharges, landslides, and land subsidence. Recent environmental assessments include participation in the Kirtland Air Force Base Installation...
A workbook for preparing surface water quality-assurance plans for districts of the U.S. Geological Survey, Water Resources Division
Donald V. Arvin
1995, Open-File Report 94-382
The U.S. Geological Survey, Water Resources Division, has a policy that each District Office is required to prepare a District Surface Water Quality-Assurance Plan. The plan for each District describes the policies and procedures that ensure high quality in the collection, processing, analysis, computer storage, and publication of surface-water data....
Analytical data from phases I and II of the Willamette River basin water quality study, Oregon
Howard E. Harrison, Chauncey W. Anderson, Frank A. Rinella, Timothy M. Gasser, Ted R. Pogue Jr.
1995, Open-File Report 95-373
This report presents trace-element, organic-compound (pesticides, volatile and semivolatile organic compounds, and dioxin and furan compounds), and nutrient concentration data from the analyses of water column, suspended-sediment, and bed-sediment samples collected by the U.S. Geological Survey as part of Phases I and II of the comprehensive Willamette River Basin Water...
Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-Determination of pesticides in water by C-18 solid-phase extraction and capillary-column gas chromatography/mass spectrometry with selected-ion monitoring
Steven D. Zaugg, Mark W. Sandstrom, Steven G. Smith, Kevin M. Fehlberg
1995, Open-File Report 95-181
A method for the isolation of 41 pesticides and pesticide metabolites in natural-water samples using C-18 solid-phase extraction and determination by capillary-column gas chromatography/mass spectrometry with selected-ion monitoring is described. Water samples are filtered to remove suspended particulate matter and then are pumped through disposable solid-phase extraction columns containing octadecyl-bonded...
Water-quality assessment of the Albemarle-Pamlico drainage basin, North Carolina and Virginia environmental setting and water-quality issues
Gerard McMahon, Orville B. Lloyd
1995, Open-File Report 95-136
The Albemarle-Pamlico drainage study unit is one of 60 units of the U.S. Geological Survey's National Water-Quality Assessment Program, and includes the large river basins which drain into the Albemarle and Pamlico Sounds-the Chowan, Roanoke, Tar-Pamlico, and Neuse River Basins. The study unit includes about 28,000 square miles and has...
Structure of the basins and ranges, Southwest New Mexico, an interpretation of seismic velocity sections
Douglas P. Klein, Gerda A. Abrams, Patricia L. Hill
1995, Open-File Report 95-506
This report presents a geologic appraisal of seismic velocity sections that profile a total of 790 km in southwest New Mexico west of Las Cruces and south of Lordsburg and Deming. The present work outlines the contribution of these velocity sections to estimating areas favorable for mineral resource occurrences. Seismic...
