Thorium resources of selected regions in the United States
Mortimer Hay Staatz, R.B. Hall, D. L. Macke, T.J. Armbrustmacher, I. K. Brownfield
1980, Circular 824
Thorium resources have been assessed in a previous report entitled 'Principal thorium resources in the United States' (Staatz and others, 1979) for (1) veins in the larger districts, {2) massive carbonatites, {3) disseminated deposits, and {4) stream placers of North and South Carolina. This report is a sequel to that...
Plan of study for the Northern Atlantic Coastal Plain Regional Aquifer System Analysis
Harold Meisler
1980, Water-Resources Investigations Report 80-16
Sediments of Cretaceous to Holocene age compose the Northern Atlantic Coastal Plain aquifer system in an area of 50,000 square miles in parts of New York, New Jersey, Delaware, Maryland, Virginia, and North Carolina. The aquifer system is a major source of water supply in the area. About 1.4 billion...
Simulation of water-quality data at selected stream sites in the Missouri River Basin, Montana
J. R. Knapton, M.A. Jacobson
1980, Water-Resources Investigations Report 80-76
Modification of sampling programs at some water-quality stations in the Missouri River basin in Montana has eliminated the means by which solute loads have been directly obtained in past years. To compensate for this loss, water-quality and streamflow data were statistically analyzed and solute loads were simulated using computer techniques.Functional...
Maps showing coal resources of the Jewell Bridge Quadrangle, Buchanan and Tazewell counties, Virginia
Kenneth J. Englund, Nancy K. Teaford
1980, Miscellaneous Field Studies Map 1211
Coal of low-volatile to high-volatile A bituminous rank is the principal developed mineral resource in the Jewell Ridge quadrangle.  The coal beds in the Jewell Ridge quadrangle contain total estimated original resources of 1,519 million tons.  Of this total, 108 million tons have been mined or lost in mining, leaving...
Distribution of nitrate in the unsaturated zone, Highland-East Highlands area, San Bernardino County, California
John M. Klein, Wesley L. Bradford
1980, Water-Resources Investigations Report 80-48
Nitrogen in the unsaturated soil zone in the Highland-East Highlands area of San Bernardino County, Calif., has been suspected as the source of nitrate in water from wells. Plans to recharge the local aquifers with imported surface water would raise the water table and intercept that nitrogen. This study was...
Statistical analyses of surface-water-quality variables in the coal area of southeastern Montana
J. R. Knapton, Rodger F. Ferreira
1980, Water-Resources Investigations Report 80-40
Since 1974 a network of water-quality stations has been operated in the coal area of southeastern Montana. This report updates a previous report with 2 years of additional data collection and presents statistics and regression equations for water-quality variables. The most apparent feature of the study is the variability of...
Water resources of the Port Gamble Indian Reservation, Washington
W. E. Lum II
1980, Water-Resources Investigations Report 79-66
This report provides information on the water resources of the Port Gamble Indian Reservation, Washington, including ground- and surface-water quality and quantity data and interpretations of the data. This information was gathered to provide a base for management and protection of the water resources of the reservation.Ground water in the...
Estimated water use in Mississippi, 1980
J.A. Callahan
1980, Open-File Report 83-224
Large quantities of good quality ground and surface water are readily available in nearly all parts of Mississippi, and there is also an abundant supply of saline water in the estuaries along the Mississippi Gulf Coast. The total estimated water use in the State in 1980 from groundwater and surface...
Ground-water hydrology of James City County, Virginia
John F. Harsh
1980, Open-File Report 80-961
Urbanization and increase in water demand prompted a 2-year study of groundwater availability and quality in the county of James City. The coastal-plain sediments, parts of which underlie the county, are the largest source of groundwater in Virginia. Four aquifers form the complex aquifer system. Hydraulic characteristics vary from aquifer...
Water table in the High Plains aquifer in 1978 in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming
Edwin D. Gutentag, John B. Weeks
1980, Open-File Report 80-50
The High Plains aquifer includes an area of about 177,000 square miles, with 74 percent of the area in Kansas, Nebraska, and Texas, and 26 percent of the area in Colorado, New Mexico, Oklahoma, South Dakota, and Wyoming. The High Plains aquifer consists of one or more hydraulically connected geologic...
Selected list of references to modern and ancient alluvial fan deposits
Tor Helge Nilsen, Thomas E. Moore
1980, Open-File Report 80-658
The following list of references on modern and ancient alluvial fan deposits has been compiled from an extensive review of the geologic literature. The information was collected as part of the process of preparing a summary paper on alluvial fan deposits for a memoir of the American Association of Petroleum...
