Publication Extents

Not all publications have extents, not all extents are completely accurate
Estuarine studies in upper Grays Harbor, Washington
Joseph P. Beverage, Milton N. Swecker
1969, Water Supply Paper 1873-B
Improved management of the water resources of Grays Harbor, Wash., requires more data on the water quality of the harbor and a better understanding of the influences of industrial and domestic wastes on the local fisheries resources. To provide a more comprehensive understanding of these influences, the U.S. Geological Survey...
Disposal of liquid wastes by injection underground--Neither myth nor millennium
Arthur M. Piper
1969, Circular 631
Injecting liquid wastes deep underground is an attractive but not necessarily practical means for disposing of them. For decades, impressive volumes of unwanted oil-field brine have been injected, currently about 10,000 acre-feet yearly. Recently, liquid industrial wastes are being injected in ever-increasing quantity. Dimensions of industrial injection wells range widely...
Scientific or rule-of-thumb techniques of ground-water management--Which will prevail?
Charles Lee McGuinness
1969, Circular 608
Emphasis in ground-water development, once directed largely to quantitatively minor (but sociologically vital) service of human and stock needs, is shifting: aquifers are treated as possible regulating reservoirs managed conjunctively with surface water. Too, emphasis on reducing stream pollution is stimulating interest in aquifers as possible waste-storage media. Such management...
Platinum, palladium, and rhodium analyses of ultramafic and mafic rocks from the Stillwater Complex, Montana
Norman J. Page, Leonard Benjamin Riley, Joseph Haffty
1969, Circular 624
Analyses by a combination fire- assay-solution-optical-emission spectrographic method of 137 rocks from the Stillwater Complex, Mont., indicate that platinum, palladium, and rhodium are preferentially concentrated in chromitite zones. The A chromitite zone (21 samples) has an average of 988.9 ppb (pans per billion, 10-9) Pt, 2290.2 ppb Pd, and 245.9...
Metalliferous deposits near Granite Mountain, eastern Seward Peninsula, Alaska
Thomas P. Miller, Raymond L. Elliott
1969, Circular 614
New deposits of lead, zinc, and silver were found in a large altered zone 18 miles long and 2 to 5 miles wide near Quartz Creek west of Granite Mountain in the eastern Seward Peninsula, Alaska. New deposits of molybdenum, bismuth, and silver were found associated with a previously reported...
Laboratory theory and methods for sediment analysis
Harold P. Guy
1969, Techniques of Water-Resources Investigations 05-C1
The diverse character of fluvial sediments makes the choice of laboratory analysis somewhat arbitrary and the pressing of sediment samples difficult. This report presents some theories and methods used by the Water Resources Division for analysis of fluvial sediments to determine the concentration of suspended-sediment samples and the particle-size distribution...
