Analog-model analysis of effect of wastewater management on the ground-water reservoir in Nassau and Suffolk Counties, New York: Report I: Proposed and current sewerage
Grant E. Kimmel, Arlen W. Harbaugh
1976, Open-File Report 76-441
By 1995, the water table may fall by as much as 5 metres (16 feet) in east-central Nassau County and as much as 1.8 metres (6 feet) in central Suffolk County as a result of proposed sewerage programs. similar, but generally slightly less, change may occur in the potentiometric head...
User's guide to the Radiometric Age Data Bank (RADB)
Robert Eugene Zartman, J. C. Cole, Richard F. Marvin
1976, Open-File Report 76-674
The Radiometric Age Data Bank (RADB) has been established by the U.S. Geological Survey, as a means for collecting and organizing the estimated 100,000 radiometric ages presently published for the United States. RADB has been constructed such that a complete sample description (location, rock type, etc.), literature citation, and extensive...
Heat flow near Charleston, South Carolina
John P. Ziagos, J.H. Sass, Robert J. Munroe
1976, Open-File Report 76-148
As part of a study of the geology and geophysics of the Charleston, South Carolina, area, thermal conductivity, thermal gradient, and heat flow were determined in a 742 meter, continuously cored, test hole. The hole is located 41 km west-northwest of Charleston near Clubhouse Corners, Figure 1, directly over a...
A reconnaissance of the effects of a forest fire on water quality in Kings Canyon National Park, California
Ray J. Hoffman, Rodger F. Ferreira
1976, Open-File Report 76-497
Following two forest fires in the Roaring River drainage basin, Kings Canyon National Park, Calif., water samples were collected from May to July 1974 to determine water-quality changes resulting from the fires. Field measurements included alkalinity , pH, specific conductance, temperature, and discharge. Samples were analyzed in the laboratory for...
Chemical characteristics of the major thermal springs of Montana
Robert H. Mariner, T. S. Presser, William C. Evans
1976, Open-File Report 76-480
Twenty-one thermal springs in western Montana were sampled for chemical, isotope, and gas compositions. Most of the springs issue dilute to slightly saline sodium-bicarbonate waters of neutral to slightly alkaline pH. A few of the springs issue sodium-mixed anion waters of near neutral pH. Fluoride concentrations are high in most...
Volcanic rocks of the McDermitt Caldera, Nevada-Oregon
Robert C. Greene
1976, Open-File Report 76-753
The McDermitt caldera, a major Miocene eruptive center is locatedin the northernmost Great Basin directly west of McDermitt, Nev. The alkali rhyolite of Jordan Meadow was erupted from the caldera and covered an area of about 60,000 sq km; the volume of rhyolite is about 960 cubic km. Paleozoic and...
Preliminary summary of the 1976 Atlantic Margin Coring Project of the U.S. Geological Survey
John Cummins Hathaway, J.J. Schlee, C. W. Poag, P. C. Valentine, Elaine G. A. Weed, Michael H. Bothner, F. A. Kohout, F.T. Manheim, R. Schloam, R.E. Miller, D.M. Schultz
1976, Open-File Report 76-844
The U.S. Geological Survey Atlantic Margin Coring Project, 1976, a 60-day expedition to obtain core samples by drilling beneath the floor of the Continental Shelf and Slope of the eastern United States, was carried out in July, August, and September 1976 aboard D/V GLOMAR CONCEPTION. The coring penetrated as much...
Buried aquifers in the Brooten-Belgrade and Lake Emily areas, west-central Minnesota--Factors related to developing water for irrigation
R. J. Wolf
1976, Water-Resources Investigations Report 76-100
Irrigation has given a substantial boost to the economy in the Brooten-Belgrade and Lake Emily areas of Minnesota. The surficial outwash aquifer is capable of yielding sufficient quantities of water for irrigation over half of its area; the remaining part may be supplied by deep aquifers. Buried glacial outwash and...
Availability and quality of ground water in the Drain-Yoncalla area, Douglas County, Oregon
J. H. Robison, C. A. Collins
1976, Water-Resources Investigations Report 76-105
The purpose of this report is to present information that may enable water users, potential water users, and planners to estimate the likelihood of obtaining ground water in adequate quantity and of suitable quality at desired locations within the study area. The Drain-Yoncalla area is in Douglas County in southwestern Oregon,...
Water resources of Lincoln County coastal area, Oregon
F. J. Frank, Antonius Laenen
1976, Water-Resources Investigations Report 76-90
The Lincoln County coastal area is underlain by Tertiary volcanic and sedimentary rocks of low permeability that store only a small volume of the annual precipitation which averages 68 inches (1,730 millimeters). Consequently, the Tertiary units yield small quantities of water to wells and furnish little ground-water discharge to maintain...
Water resources of the Rainy Lake watershed, northeastern Minnesota
Donald W. Ericson, Gerald F. Lindholm, John O. Helgesen
1976, Hydrologic Atlas 556
The watershed includes 1,481 lakes that are 10 acres (4 square hectometers) or larger (Minnesota Division of Waters, Soils, and Minerals, 1968). The area of these lakes total about 435,000 acres (176,000 hm2) or 15 percent of the watershed. Most of the lakes are smaller than 250 acres (101 hm2)...
Water resources of the North Coast Limestone area, Puerto Rico
Ennio V. Giusti, Gordon D. Bennett
1976, Water-Resources Investigations Report 75-42
The north-coast limestone area, about 600 square miles, is one of the few sparsely populated parts of Puerto Rico, and is the island 's last large and underdeveloped source of ground water. The area 's limestone aquifers are (from oldest to youngest): the Lares Limestone, the Cibao Formation, the Aguada...
Geochemical maps showing the distribution and abundance of beryllium in the Tanacross Quadrangle, Alaska
G.C. Curtin, G.W. Day, S.P. Marsh, R. B. Tripp
1976, Miscellaneous Field Studies Map 767-L
This series of geochemical maps shows the distribution of beryllium in three sample media: (A) the oxide residue (the oxalic-acid-leachable fraction) of the stream sediment, (B) the minus-80-mesh stream sediment, and (C) the ash of aquatic bryophytes (mosses). The geochemical data are plotted on a base map that shows generalized...
Oxalic-acid leaching of rock, soil, and stream-sediment samples as an anomaly-accentuated technique
Henry V. Alminas, Elwin L. Mosier
1976, Open-File Report 76-275
In many instances total-rock and sieved-soil and stream-sediment samples lack the sensitivity and contrast required for reconnaissance exploration and necessary in the search for blind ore deposits. Heavy-mineral concentrates incorporate the required sensitivity and contrast but are overly expensive for two reasons: time-consuming sample preparation is required to obtain them,...
