Water resources of Massachusetts
Alison C. Simcox
1992, Water-Resources Investigations Report 90-4144
This report describes the water resources of Massachusetts. It contains sections describing the location, use, quality, and management of water resources in Massachusetts, followed by a summary of the surface water and ground-water resources of all 27 river basins designated by the State for planning purposes. The data for each...
Acid rain and its effects on streamwater quality on Catoctin Mountain, Maryland
Karen C. Rice, O.P. Bricker
1992, Open-File Report 92-168
The U.S. Geological Survey (USGS) is the Nation's largest water-science and water-information agency. The mission of the Water Resources Division of the USGS is to provide the hydrologic information and understanding needed for the best management of the Nation's water resources. To fulfill this mission, the USGS conducts water-quality and...
Mineral and energy resource assessment maps of the Mount Katmai, Naknek, and western Afognak quadrangles, Alaska
S. E. Church, J.R. Riehle, L. B. Magoon, D. L. Campbell
1992, Miscellaneous Field Studies Map 2021-F
On the basis of new geologic mapping and exploration geochemical studies, we have provided a mineral and energy resource assessment of the Mount Katmai, Naknek, and western Afognak quadrangles, Alaska. We delineate four tracts of ground that have metallic mineral resources. The mineral deposit types considered in each tract are...
A summary of water-resources activities of the U.S. Geological Survey in Iowa, fiscal year 1992
1992, Open-File Report 92-154
Water-resources activities of the U.S. Geological Survey in Iowa consist of collecting hydrologic data and conducting interpretive studies. Hydrologic investigations in Iowa are made through three basic types of projects: (1) hydrologic data-collection programs; (2) local or areal studies; and (3) statewide or regional investigations. These projects are funded through...
Hydrologic data for the Big Spring basin, Clayton County, Iowa, water year 1990
Stephen J. Kalkhoff, R.L. Kuzniar, D. Kolpin, C.A. Harvey
1992, Open-File Report 92-67
Hydrologic data were collected in the Big Spring basin located in Clayton County, Iowa, during the 1990 water year. The data were collected by the U.S. Geological Survey in cooperation with the Iowa Department of Natural Resources, Geological Survey Bureau, to provide information on variation and movement of agricultural chemicals...
Geohydrologic systems in Kansas; physical framework of the confining unit in the Western Interior Plains aquifer system
C. V. Hansen, R. J. Wolf, J. M. Spinazola
1992, Hydrologic Atlas 722-E
The purpose of this Hydrologic Investigations Atlas is to provide a description of the geohydrologic systems in Upper Cambrian through Lower Cretaceous rocks in Kansas. This investigation was made as part of the Central Midwest Regional Aquifer-System Analysis (CMRASA). The CMRASA is one of several major investigations by the U.S....
Selected meteorological data for an arid site near Beatty, Nye County, Nevada, calendar year 1987
James L. Wood, Jeffrey M. Fischer
1992, Open-File Report 92-59
Selected meteorological data were collected at a study site adjacent to a low-level radioactive-waste burial facility near Beatty, Nevada, for calendar year 1987. Data were collected in support of an ongoing study to estimate the potential for downward movement of radionuclides into the unsaturated sediments beneath waste-burial trenches at the...
Hydrogeologic maps of the central Oklahoma aquifer, Oklahoma
Scott C. Christenson, Robert B. Morton, Benard A. Mesander
1992, Hydrologic Atlas 724
This report presents hydrogeologic maps of the Central Oklahoma aquifer. The maps were prepared by measuring water levels in wells during the winder of 1986 and 1987; examination of geophysical logs to determine the altitudes of the top of selected geologic units and the base of fresh ground water; and...
A modular finite-element model (MODFE) for areal and axisymmetric ground-water-flow problems; Part 1, Model description and user's manual
Lynn J. Torak
1992, Open-File Report 90-194
A MODular, Finite-Element digital-computer program (MODFE) was developed to simulate steady or unsteady-state, two-dimensional or axisymmetric ground-water flow. Geometric- and hydrologic-aquifer characteristics in two spatial dimensions are represented by triangular finite elements and linear basis functions; one-dimensional finite...
Records of wells in sandstone and alluvial aquifers and chemical data for water from selected wells in the Navajo aquifer in the vicinity of the greater Aneth Oil Field, San Juan County, Utah
Lawrence E. Spangler
1992, Open-File Report 92-124
This report contains hydrologic data for wells finished in sandstone and alluvial aquifers in southeastern San Juan County, Utah, and chemical data for water from selected wells in the Navajo aquifer. Temperature, specific conductance, pH, and discharge data from 1989-91 for water from selected wells in all aquifers are also...
Sediment properties and water movement through shallow unsaturated alluvium at an arid site for disposal of low-level radioactive waste near Beatty, Nye County, Nevada
Jeffrey M. Fischer
1992, Water-Resources Investigations Report 92-4032
A commercial disposal facility for low-level radioactive waste has been in operation near Beatty, Nevada, since 1962. The facility is in the arid Amargosa Desert where wastes are buried in trenches excavated into unsaturated alluvial sediments. Thick unsaturated zones in arid environments offer many potential advantages for disposal of radioactive...
Hydro-climatic data network (HCDN); a U.S. Geological Survey streamflow data set for the United States for the study of climate variations, 1874-1988
J. R. Slack, Jurate Maciunas Landwehr
1992, Open-File Report 92-129
Records of streamflow can provide an account of climatic variation over a hydrologic basin. The ability to do so is conditioned on the absence of confounding factors that diminish the climate signal. A national data set of streamflow records that are relatively free of confounding anthropogenic influences has been developed...
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...
