A one-dimensional, steady-state dissolved-oxygen model and waste-load assimilation study for Cedar Creek, Dekalb and Allen counties, Indiana
William G. Wilber, James G. Peters, Mark A. Ayers, Charles G. Crawford
1979, Open-File Report 79-1062
The Indiana State Board of Health is developing a State water-quality management plan that includes the establishing of limits for wastewater effluents discharged into Indiana streams. A digital model calibrated to conditions in Cedar Creek was used to develop alternatives for future waste loadings that would be compatible with Indiana...
Pliocene intrusive rocks and mineralization near Rico, Colorado
Charles W. Naeser, C. G. Cunningham, R. F. Marvin, J. D. Obradovich
1979, Open-File Report 79-1093
Fission-track and potassium-argon studies of intrusive rocks in the vicinity of Rico, Colorado, have shown that at least two periods of igneous activity occurred and that significant ore mineralization is associated with alaskites and latites that are 3 to 5 million years old. Discordant fission-track ages of apatite and zircon...
An oilspill risk analysis for the Northern Gulf of Alaska (proposed sale 55), Outer Continental Shelf lease area
Kenneth J. Lanfear, Anastasis Nakassis, William B. Samuels, C.T. Schoen
1979, Open-File Report 79-1284
An oilspill risk analysis was conducted to determine the relative environmental hazards of developing oil in different regions of the Northern Gulf of Alaska Outer Continental Shelf lease area. The study analyzed the probability of spill occurrences, likely paths of the spilled oil, and locations of resources vulnerable to spilled...
Resource report for the deep-water areas of proposed OCS lease sale No. 70, St. George Basin, Alaska
Alan K. Cooper, D.W. Scholl, T.L. Vallier, E. W. Scott
1979, Open-File Report 80-246
This report summarizes geological and geophysical data from the deep-water (greater than 200m) region of the St. George Basin lease sale area #70. The shallow-water region is discussed in detail by Marlow and others (1979a) in a companion report. The triangular deep-water region lies at the junction of the Bering...
Mineralization and gossans in the Wadi Wassat-Wadi Qatan region, Kingdom of Saudi Arabia
Christopher F. Blain
1979, Open-File Report 79-671
Very large bodies of stratabound iron sulfides in volcanic rocks of the Wadi Wassat-Wadi Qatan region of Saudi Arabia are capped at surface by numerous iron oxide-rich gossan outcrops. The gossan at Hadbah overlies a low-grade nickel-bearing sulfide body, but most of the sulfide lenses are almost devoid of base...
Water resources of the Port Madison Indian Reservation, Washington
W. E. Lum II
1979, Water-Resources Investigations Report 78-112
The study summarized in this report was made to provide Suquamish Tribal leaders with information on the reservation's surface- and ground-water resources. The Tribal leaders need this information to help them manage and protect their water resources against overdevelopment. The quantity of ground water that is estimated to be available...
Measured stratigraphic sections of Jurassic San Rafael Group and adjacent rocks in Emery and Sevier counties, Utah
J.C. Wright, D.D. Dickey, R.P. Snyder, L.C. Craig, R. A. Cadigan
1979, Open-File Report 79-1317
These sections were measured prior to 1960, before adoption of the metric system. Publication was delayed by other assignments of the authors and later by the untimely death of J. C. Wright. They are being released at this time because of the increased interest in the uranium potential of Jurassic...
A one-dimensional, steady-state, dissolved-oxygen model and waste-load assimilation study for the Mississinewa River, Grant County, Indiana
William G. Wilber, Charles G. Crawford, James G. Peters
1979, Open-File Report 79-1534
The Indiana State Board of Health is developing a State water-quality management plan that includes establishing limits for wastewater effluents discharged into Indiana streams. A digital model calibrated to conditions in the Mississinewa River was used to develop alternatives for future waste loadings that would be compatible with Indiana stream...
Measured sections of Ordovician strata in northeast Kentucky
Gordon Whitney Weir, Warren Lee Peterson, W. C. Swadley
1979, Open-File Report 79-1663
The sections described in this report are part of the data used in studies of the Upper Ordovician rocks of Kentucky. The studies were part of a geologic mapping program by the U. S. Geological Survey in cooperation with the Kentucky Geological Survey. Formations of Late Ordovician age described in...
Quantity and quality of urban runoff from three localities in the Denver Metropolitan area, Colorado
Sherman R. Ellis, William M. Alley
1979, Water-Resources Investigations Report 79-64
Considerable variation in constituent concentrations was shown in urban runoff data for 1975-77 from three metropolitan Denver drainage basins. Constituent concentrations, greatest during initial rainfall runoff, generally peaked midday of snowmelt runoff, corresponding with maximum melting and runoff. Instantaneous loads of constituents were largely a function of discharge. Days since...
Chemical analyses of coal from the Tongue River Member, Fort Union Formation, Decker coal deposit, Big Horn County, Montana
Ronald H. Affolter, Joseph R. Hatch, Robert E. Matson, L.A. Sauer
1979, Open-File Report 79-772
As part of a continuing cooperative program between the U. S. Geological Survey and the Montana Bureau of Mines and Geology to collect and chemically analyze representative samples of Montana coals, 50 coal and 2 carbonaceous shale samples were collected from the Anderson, Dietz 1 and Dietz 2 coal beds...
Water-quality data from a landfill, Pinellas County, Florida, May 1975-October 1977
Mario Fernandez
1979, Open-File Report 78-822
Ground water in and near a proposed landfill site can become contaminated by leachates from the fill material. Realizing that potential, Pinellas County entered into a cooperative investigation with the U.S. Geological Survey to determine background water-quality conditions, and to evaluate the potential effects of landfill leachate on the quality...
