Determination of minor elements in water by emission spectroscopy
Paul R. Barnett, E. C. Mallory
1971, Techniques of Water-Resources Investigations 05-A2
With the emission spectrograph, the analyst is able to determine many minor elements simultaneously in water samples. Spectrographic methods differ chiefly in techniques of preconcentrating the elements. For waters with dissolved solids of less than 1,000 milligrams per liter, the method of evaporating to dryness and determining the elements in...

Reconnaissance of selected minor elements in surface waters of the United States, October 1970
W. H. Durum, John David Hem, Sumner Griggs Heidel
1971, Circular 643
A nationwide reconnaissance of selected minor elements in water resources of the 50 States and Puerto Rico was made by the U.S. Geological Survey in cooperation with the U.S. Bureau of Sport Fisheries and Wildlife during autumn, 1970. Initiated in response to the growing need for data on minor elements...
A procedure for evaluating environmental impact
Luna Bergere Leopold, Frank Eldridge Clarke, Bruce B. Hanshaw, James R. Balsley
1971, Circular 645
In a recent article in "Science" discussing the Environmental Policy Act of 1969, Gillette (1971) states "The law's instructions for preparing an impact report apparently are not specific enough to insure that an agency will fully, or even usefully, examine the environmental effects of the projects it plans." This report...
Application of borehole geophysics to water-resources investigations
W.S. Keys, L.M. MacCary
1971, Techniques of Water-Resources Investigations 02-E1
This manual is intended to be a guide for hydrologists using borehole geophysics in ground-water studies. The emphasis is on the application and interpretation of geophysical well logs, and not on the operation of a logger. It describes in detail those logging techniques that have been utilized within the Water...
Analysis of stream-temperature variations in the Upper Delaware River Basin, New York
Owen O. Williams
1971, Water Supply Paper 1999-K
The effect of climatologic conditions and reservoir releases on downstream conditions was determined by means of statistical and graphical analyses of stream-temperature variations measured in the upper Delaware River basin, May-September 1964-67. Climatologic conditions normally increase water temperatures from February through July and decrease them from August through January. Summer...

Summary of data on temperature of streams in North Carolina, 1943-67
Thomas H. Woodard
1971, Water Supply Paper 1895-A
This report summarizes stream-temperature data collected by the U.S. Geological Survey in cooperation with the State of North Carolina during the period 1943-67. Listed in two tables are summary values determined from records from 176 locations throughout the State. Of the 850 station years of record, 31 percent is monthly...
Floods of December 1964 and January 1965 in the Far Western States; Part 1 Description
A. O. Waananen, D.D. Harris, R.C. Williams
1971, Water Supply Paper 1866-A
The floods of December 1964 and January 1965 in the Far Western States were extreme; in many areas, the greatest in the history of recorded streamflow and substantially greater than those of December 1955. An unusually large area--Oregon, most of Idaho, northern California, southern Washington, and small areas in western...

Microearthquake activity in the vicinity of Wooded Island, Hanford region, Washington
Andrew M. Pitt
1971, Open-File Report 71-226
The U.S. Geological Survey (U.S.G.S.) began to monitor microearthquake activity in the region of the Atomic Energy Commission's Hanford Reservation in south-central Washington in March 1969. The Division of Reactor Development and Technology (DRDT), of the Atomic Energy Commission (AEC), supported the operation of a network of 6 (later 7)...

Estimated subsidence in the Raymond Basin, Los Angeles County, California, for a postulated water-level lowering, 1970-2020
Ben Elder Lofgren
1971, Open-File Report 71-184
One of the alternate plans for water utilization being considered by the California Department of Water Resources in the Raymond Basin in southern California involves partial mining of ground water during the period 1970-2020, and consequent substantial lowering of water levels. The Department wants to know whether land subsidence would...
