Procedures for assessment of cumulative impacts of coal mining on the hydrologic balance
Alan M. Lumb
1982, Open-File Report 82-334
Techniques were developed to assess the probable cumulative impacts of anticipated surface mining upon the hydrology of and area. An activity profile of cumulative drainage area versus river miles downstream from the surface mining site is constructed that shows major water uses, flood prone areas, and stream classifications. From the...
Uranium potential of the Burro Canyon Formation in western Colorado
L.C. Craig
1982, Open-File Report 82-222
The Burro Canyon Formation of Early Cretaceous age overlies the Morrison Formation (Late Jurassic) and underlies the Dakota Sandstone (Late Cretaceous) over most of southeastern Utah and southwestern Colorado. It consists mainly of alternating beds of fluvial sandstone and overbank mudstone with sandstone dominating in the lower part of the...
Origin of the Mariano Lake uranium deposit, McKinley County, New Mexico
Neil S. Fishman, Richard L. Reynolds
1982, Open-File Report 82-888
The Mariano Lake uranium deposit, hosted by the Brushy Basin Member of the Jurassic Morrison Formation, occurs in the trough of an east-west trending syncline at the western end of the Smith Lake-Mariano Lake group of uranium deposits near Crownpoint, New Mexico. The orebody, which contains abundant amorphous organic material,...
Progress report on geologic studies of the Ranger orebodies, Northern Territory, Australia
J. T. Nash, David Frishman
1982, Open-File Report 82-936
The Ranger No. 1 and No. 3 orebodies contain about 124,000 tonnes U3O8 in highly chloritized metasediments of the lower Proterozoic Cahill Formation within about 500 m of the projected sub-Kombolgie Formation unconformity. In both orebodies, oxidized and reduced uranium minerals occur chiefly in quartzose schists that have highly variable...
Sewage plume in a sand and gravel aquifer, Cape Cod, Massachusetts
Denis LeBlanc
1982, Open-File Report 82-274
Secondarily treated domestic sewage has been disposed of on surface sand beds at the sewage treatment facility at Otis Air Force Base, Massachusetts, since 1936. Infiltration of the sewage through the sand beds into the underlying unconfined sand and gravel aquifer has resulted in a plume of sewage-contaminated ground water...
Potential hydrologic impacts of ground-water withdrawal from the Cape Cod National Seashore, Truro, Massachusetts
Denis R. LeBlanc
1982, Open-File Report 82-438
The hydrologic impacts of continuous ground-water withdrawals at 0.75, 1.0, and 1.24 Mgal/d (million gallons per day) from a test-well site in the Cape Cod National Seashore, Truro, Massachusetts, were evaluated with a three-dimensional finite-difference steady-state-flow digital model. The digital model was prepared during an earlier study and is only...
Environmental geology of Harrison Bay, northern Alaska
J.D. Craig, G. P. Thrasher
1982, Open-File Report 82-35
The surficial and shallow subsurface geology of Harrison Bay on the Beaufort Sea coast was mapped as part of the U.S. Geological Survey's prelease evaluation for Outer Continental Shelf (OCS) Oil and Gas Lease Sale 71. During the 1980 summer season, approximately 1600 km of multisensored, high-resolution geophysical profile data...
The design of a microprocessor-based data logger
K.J. Leap, L.A. Dedini
1982, Open-File Report 82-167
The design of a microprocessor-based data logger, which collects and digitizes analog voltage signals from a continuous-measuring instrumentation system and transmits serial data to a magnetic tape recorder, is discussed. The data logger was assembled from commercially-available components and can be user-programmed for greater flexibility. A description of the data...
Water use in Wisconsin, 1979
C.L. Lawrence, B.R. Ellefson
1982, Water-Resources Investigations Report 82-444
This report summarizes the uses of water in Wisconsin for 1979, except aesthetics, navigation, and recreational use. The greatest single use of water, an instream use, was for hydroelectric power production. About 26 trillion gallons, or 93 percent, was used for this purpose. Of the other 7 percent where water is...
