Records of wells and chemical analyses of water from wells for the period June 13, 1984 to December 4, 1986 at the Maxey Flats Radioactive Waste Disposal Site, Kentucky
M. A. Lyverse
1987, Open-File Report 87-214
Lithologic data are presented for 113 wells drilled at the Maxey Flats Radioactive Waste Disposal Site for the period June 13, 1984 to December 4, 1986. Water levels, tritium concentrations, and specific conductance are also presented for wells yielding sufficient water for measuring and sampling. At least one sample was...
Analytically-derived sensitivities in one-dimensional models of solute transport in porous media
D.S. Knopman
1987, Open-File Report 86-605
Analytically-derived sensitivities are presented for parameters in one-dimensional models of solute transport in porous media. Sensitivities were derived by direct differentiation of closed form solutions for each of the odel, and by a time integral method for two of the models. Models are based on the advection-dispersion equation and include...
Records of wells and chemical analyses of ground water in Campbell County, South Dakota
K.M. Neitzert, N.C. Koch
1987, Open-File Report 87-42
Well and chemical groundwater data contained in two tables were collected during a 3-yr study started in 1964 to determine the geology and water resources of Campbell County, South Dakota. Physical, hydrologic, and geologic data for 631 wells and test holes have been entered into computer storage in the Groundwater...
Data for selected pesticides and volatile organic compounds for wells in the western San Joaquin Valley, California, February to July 1985
J. M. Neil
1987, Open-File Report 87-48
During February to July 1985, water samples were collected from 55 wells in the western San Joaquin Valley, California, for chemical analysis to determine if 20 selected pesticides and 26 volatile organic compounds were present. Twenty-six of the sampled wells are completed in the shallow unconfined regional aquifer and 29...
Estimation of the recharge area contributing water to a pumped well in a glacial-drift, river-valley aquifer
D. J. Morrissey
1987, Open-File Report 86-543
The highly permeable, unconfined, glacial drift aquifers that occupy most New England river valleys constitute the principal source of drinking water for many communities that obtain part or all of their public water supply from groundwater. Analytical , two-dimensional numerical and three-dimensional numerical models were used to delineate contributing areas...
Geologic map of the Chelan 30-minute by 60-minute quadrangle, Washington
R. W. Tabor, V. A. Frizzell Jr., J. T. Whetten, R. B. Waitt Jr., D. A. Swanson, G. R. Byerly, D. B. Booth, M. J. Hetherington, R. E. Zartman
1987, IMAP 1661
Summary -- The Chelan quadrangle hosts a wide variety of rocks and deposits and display a long geologic history ranging from possible Precambrian to Recent. Two major structures, the Leavenworth and Entiat faults divide cross the quadrangle from southeast to northwest and bound the Chiwaukum 'graben', a structural low preserving...
Effects of surface coal mining and reclamation on the geohydrology of six small watersheds in west-central Indiana
Jeffrey D. Martin, Richard F. Duwelius, Charles G. Crawford
1987, Open-File Report 87-210
The watersheds studied include mined and reclaimed; mined and unreclaimed; and unmined, agricultural land uses, and are each < 3 sq mi in area. Surface water, groundwater, and meteorologic data for the 1981 and 1982 water years were used to describe and compare hydrologic systems of the six watersheds and...
Rainfall and runoff quantity and quality data collected at four urban land-use catchments in Fresno, California, October 1981-April 1983
R.N. Oltmann, J. R. Guay, J. M. Shay
1987, Open-File Report 84-718
Data were collected as part of the National Urban Runoff Program to characterize urban runoff in Fresno, California. Rainfall-runoff quantity and quality data are included along with atmospheric dry-deposition and street-surface particulate quality data. The data are presented in figures and tables that reflect four land uses: industrial, single-dwelling residential,...
North Dakota ground-water quality
George Garklavs, Rick Nelson
1987, Open-File Report 87-744
This report contains summary information on ground-water quality in one of the 50 States, Puerto Rico, the Virgin Islands, or the Trust Territories of the Pacific Islands, Saipan, Guam, and American Samoa. The material is extracted from the manuscript of the 1986 National Water Summary, and with the exception of...
