Quality-assurance plan for the analysis of fluvial sediment by laboratories of the U.S. Geological Survey
Wilbur J. Matthes, Clyde J. Sholar, John R. George
1992, Open-File Report 91-467
This report describes procedures used by the Iowa District sediment laboratory of the U.S. Geological Survey to assure the quality of sediment-laboratory data. These procedures can be used by other U.S. Geological Survey laboratories regardless of size and type of operation for quality assurance and quality control of specific sediment-laboratory...
International strategic minerals inventory summary report; vanadium
I. Goldberg, E.C.I. Hammerbeck, L.S. Labuschagne, C. Rossouw
1992, Circular 930-K
Major world resources of vanadium are described in this summary report of information in the International Strategic Minerals Inventory (ISMI). ISMI is a cooperative data-collection effort of earth-science and mineral-resource agencies in Australia, Canada, the Federal Republic of Germany, the Republic of South Africa, the United Kingdom, and the United...
Geohydrologic and chemical data from wells in the Mud Lake area, eastern Idaho, 1988-91
Joseph M. Spinazola, Annette M. Tungate, T. L. Rogers
1992, Open-File Report 92-133
Well information, results of test drilling, water-level measurements in observation wells, and chemical and isotopic constituents in ground-water samples were among the data collected as part of a study of the availability of ground water from the eastern Snake River Plain aquifer system in the Mud Lake area of eastern...
Modifications of the U.S. Geological Survey modular, finite-difference, ground-water flow model to read and write geographic information system files
Leonard L. Orzol, Timothy S. McGrath
1992, Open-File Report 92-50
This report documents modifications to the U.S. Geological Survey modular, three-dimensional, finite-difference, ground-water flow model, commonly called MODFLOW, so that it can read and write files used by a geographic information system (GIS). The modified model program is called MODFLOWARC. Simulation programs such as MODFLOW generally require large amounts of...
Selected hydrologic data for Cache Valley, Utah and Idaho, 1969-91
D. Michael Roark, Karen M. Hanson
1992, Open-File Report 92-173
This report contains hydrologic data collected in Cache Valley from 1969 to 1991. The report area is in north-central Utah and southeast Idaho, within the Basin and Range physiographic province described by Fenneman (1931), and includes about 660 square miles.Most of the data in this report were collected by the...
Geologic and hydrologic data collected at test holes NC-4 and NC-14, Manati and Vega Baja, Puerto Rico
Jesús Rodríguez-Martínez, Richard A. Scharlach, Arturo Torres-Gonzalez
1992, Open-File Report 92-126
Test holes NC-4 and NC-14 were drilled in the municipalities of Manati and Vega Baja, respectively, in northern Puerto Rico as part of a study of the ground-water resources in the Northern Coastal Province of Puerto Rico. This study was conducted from 1986 to 1988 by the U.S. Geological Survey...
The ground-water-level monitoring network in Iowa
R.B. Lambert
1992, Open-File Report 92-27
The ground-water-level monitoring network in Iowa consists of 202 wells completed in the principal bedrock and surficial aquifers that supply ground water to numerous users throughout the State. The bedrock aquifers include the Cambrian-Ordovician aquifer system, the Silurian-Devonian aquifer, the Mississippian aquifer, localized Pennsylvanian aquifers, and the Dakota aquifer. The...
Hydrogeology, water quality, and potential for transport of organochlorine pesticides in ground water at the North Hollywood Dump, Memphis, Tennessee
R. E. Broshears, M. W. Bradley
1992, Water-Resources Investigations Report 91-4022
Geologic, hydrologic, and water-quality data indicate that ground-water contamination is confined to shallow horizons within the unconfined aquifer underlying the North Hollywood Dump in Memphis, Tennessee. The dump is a closed municipal-industrial landfill that has been ranked as Tennessee's potentially most dangerous hazardous-waste site. Toxic constituents of concern at the...
Hydrogeology, ground-water quality, and potential for water-supply contamination near the Shelby County landfill in Memphis, Tennessee
W. S. Parks, J. E. Mirecki
1992, Water-Resources Investigations Report 91-4173
An investigation was conducted from 1989 to 1991 to collect and interpret hydrogeologic and ground-water-quality data specific to the Shelby County landfill in east Memphis, Tennessee. Eighteen wells were installed in the alluvial and Memphis aquifers at the landfill. Hydrogeologic data collected showed that the confining unit separating the alluvial...
