Organic solutes in ground water at the Idaho National Engineering Laboratory
Jerry A. Leenheer, Jefferson C. Bagby
1982, Water-Resources Investigations Report 82-15
In August 1980, the U.S. Geological Survey started a reconnaissance survey of organic solutes in drinking water sources, ground-water monitoring wells, perched water table monitoring wells, and in select waste streams at the Idaho National Engineering Laboratory (INEL). The survey was to be a two-phase program. In the first phase,...
Hydrotectonics; principles and relevance
R. W. Kopf
1982, Open-File Report 82-307
Hydrotectonics combines the principles of hydraulics and rock mechanics. The hypothesis assumes that: (1) no faults are truly planar, (2) opposing noncongruent wavy wallrock surfaces form chambers and bottlenecks along the fault, and (3) most thrusting occurs beneath the water table. These physical constraints permit the following dynamics. Shear displacement...
Water-level maps of the alluvial aquifer, northwestern Mississippi April 1982
Daphne Darden
1982, Water-Resources Investigations Report 82-4061
Water levels were measured in about 500 wells in the Mississippi River valley alluvial aquifer in northwestern Mississippi during the period April 12-23, 1982. The water-level change from April 1981 to April 1982, showed a general decline, but the water-level change from September 1981 to April 1982 showed some recovery....
Hydrogeologic and water-quality characteristics of the Ironton-Galesville aquifer, southeast Minnesota
J. F. Ruhl, R. J. Wolf, D. G. Adolphson
1982, Water-Resources Investigations Report 82-4080
Quality of water in the Ironton-Galesville aquifer is generally acceptable for all kinds of uses. Calcium magnesium bicarbonate type water is most common. The dissolved-solids concentration ranges from about 200 to 1,000 milligrams per liter. The lowest values are in the northern part of the aquifer, where the bedrock is...
Acoustic systems for the measurement of streamflow
Antonius Laenen, Winchell Smith
1982, Open-File Report 82-329
Very little information is available concerning acoustic velocity meter (AVM) operation, performance, and limitations. This report provides a better understanding about the application of AVM instrumentation to streamflow measurment. Operational U.S. Geological Survey systems have proven that AVM equipment is accurate and dependable. AVM equipment has no practical upper limit...
Organic geochemistry of sediments on the flanks of Tanner and Cortes banks offshore from southern California
J. B. Rapp, K.A. Kvenvolden
1982, Open-File Report 82-829
Holocene sediment, composed mainly of foram tests, occurs on the flanks of the Tanner and Cortes Banks, offshore southern California. The organic matter in this sediment differs in content and composition from the organic matter in nearby basins. Two sources of hydrocarbons are indicated: terrestrial plants and biodegraded or immature...
