Hydrology of potential mining areas in the Warrior coal field, Alabama
Celso Puente, J.G. Newton
1982, Open-File Report 82-105
Hydrologic data for four small basins and for numerous other sites in the Warrior coal field are used to define the potential impact of surface mining on water resources. Bear and Blue Creek basins are underlain predominantly by relatively impermeable consolidated rocks in the Pottsville Formation. Turkey and Yellow Creek...
Geohydrologic descriptions of selected solid waste disposal sites in Puerto Rico
Arturo Torres-Gonzalez, Fernando Gómez-Gómez
1982, Open-File Report 81-490
Fifty solid-waste disposal sites in Puerto Rico were examined in 1977 and ranked according to their potential for degradation of the water resources. Twenty-five of the sites show significant leachate pollution potential. The cover material at 21 sites is relatively permeable and offers insignificant attenuation to leachates. Thirty-six sites are...
Simulated changes in water levels in the Minjur Aquifer, Riyadh area, Saudi Arabia
J. F. Williams, I.A. Sagaby
1982, Open-File Report 82-371
A two-dimensional finite-difference computer model of the Minjur aquifer in the Riyadh area of Saudi Arabia was developed to simulate and predict drawdown in an aquifer which, in 1979, supplied more than 80 percent of all water used in this capital area. The Minjur was modeled as a confined aquifer...
Uranium in Wheeler Basin, Grand County, Colorado
E. J. Young
1982, Open-File Report 82-730
Two kinds of radioactive anomalies are found in Wheeler Basin, both of which consist of biotite concentrations in Precambrian rocks, but the ones in migmatized biotite gneiss contain uraninite and the ones in Silver Plume Granite probably do not. At least 18 new uranium occurrences were found, most of which...
An alternative hypothesis for sink development above salt cavities in the Detroit area
Daniel Stump, A.S. Nieto, J. R. Ege
1982, Open-File Report 82-297
Subsidence and sink formation resulting from brining operations in the Windsor-Detroit area include the 1954 sink at the Canadian Salt Company brine field near Windsor, Ontario, and the 1971 sinks at the BASF Wyandotte Corporation brine field at Grosse Ile, Mich. Earlier investigations into both occurrences concluded that the mechanism...
Water resources of Rockland Basin, southeastern Idaho
Rhea P. Williams, H.W. Young
1982, Open-File Report 82-755
Rockland basin comprises about 320 sq mi of the Snake River drainage in southeastern Idaho. Mountain ranges bordering the basin are composed predominantly of limestone and are complexly faulted. Major aquifers include Holocene alluvium, Quaternary-Tertiary volcanic rocks, and Tertiary sedimentary rocks. Groundwater occurs under water table conditions except where it...
Plan for hydrologic study of an area to be surface mined for coal in northwestern Colorado
Robert S. Williams, Nancy E. Driver
1982, Open-File Report 82-874
A data-collection network was established in 1980 in northwestern Colorado in a drainage basin which may be surface mined for coal. This report describes the work plan set up to study the premining hydrology of this area near Steamboat Springs, Routt County, Colorado. The bedrock, alluvial, and surface-water systems as...
Water-quality assessment of the Merced River, California
Stephen K. Sorenson
1982, Open-File Report 82-450
The Merced River and its major tributaries have been subject of water-quality and water-quantity studies by local, State, and Federal agencies since before 1900. Data have been compiled and analyzed, and even though water-quality problems exist in the basin, the water generally is of good quality for most of the...
Multielement chemical and statistical analyses from a uranium hydrogeochemical and stream-sediment survey in and near the Elkhorn Mountains, Jefferson County, Montana. Part I: Surface water
V. J. Suits, K. J. Wenrich
1982, Open-File Report 82-203-A
Fifty-two surface-water samples, collected from an area south of Helena, Jefferson County, were analyzed for 51 chemical species. Of these variables, 35 showed detectable variation over the area, and 29 were utilized in a correlation analysis. Two populations are distinguished in the collected samples and are especially evident in the...
Thermal springs in the Salmon River basin, central Idaho
H.W. Young, R.E. Lewis
1982, Open-File Report 82-104
The Salmon River basin drains approximately 13,000 square miles in central Idaho underlain by the Idaho batholith. Geologic units in the basin include igneous, sedimentary, and metamorphic rocks and granitic rocks predominate. Water from thermal springs ranges in temperature from 20.5 degrees to 94.0 degrees Celsius. The waters are slightly...
