Determination of phenoxy acid herbicides in water by electron-capture and microcoulometric gas chromatography
D.F. Goerlitz, William L. Lamar
1967, Water Supply Paper 1817-C
A sensitive gas chromatographic method using microcoulometric titration and electron-capture detection for the analysis of 2,4-D, silvex, 2,4,5-T, and other phenoxy acid herbicides in water is described. The herbicides are extracted from unfiltered water samples (800-1,000 ml) by use of ethyl ether ; then the herbicides are concentrated and esterilied....
Water requirements of the iron and steel industry
Faulkner B. Walling, Louis Ethelbert Otts Jr.
1967, Water Supply Paper 1330-H
Twenty-nine steel plants surveyed during 1957 and 1958 withdrew from various sources about 1,400 billion gallons of water annually and produced 40.8 million tons of ingot steel. This is equivalent to about 34,000 gallons of water per ton of steel. Fifteen iron ore mines and fifteen ore concentration plants together...
Water resources of the Marquette Iron Range area, Michigan
Sulo Werner Wiitala, Thomas Gwyn Newport, Earl L. Skinner
1967, Water Supply Paper 1842
Large quantities of water are needed in the beneficiation and pelletizing processes by which the ore mined from low-grade iron-formations is upgraded into an excellent raw material for the iron and steel industry. Extensive reserves of low-grade iron-formation available for development herald an intensification of the demands upon the area's...
The geohydrology of Pinnacles National Monument, California
J. P. Akers
1967, Open-File Report 67-2
Water supplies for Pinnacles National Monument are obtained from a collection gallery in alluvium and from a flowing well which obtains water from fractured breccia and tuff near a fault.Rocks other than alluvium, in all but the northern fourth of the monument, are dense igneous or metamorphic types that, unless...
Measurement of peak discharge at dams by indirect methods
Harry Hulsing
1967, Techniques of Water-Resources Investigations 03-A5
This chapter describes procedures for measuring peak discharges using dams, weirs, and embankments. Field and office procedures limited to this method are described. Discharge coefficients and formulas are given for three general classes of weirs-sharp-crested, broad-crested, and round-crested-and for highway embankments and weirs of unusual shape. The effects of...
Ground-water levels in observation wells in Oklahoma, 1965-66
D.L. Hart Jr.
1967, Open-File Report 67-285
The investigation of the ground-water resources of Oklahoma by the U.S. Geological Survey in cooperation with the Oklahoma Water Resources Board includes a continuing program to collect records of water levels in selected observation wells on a systematic basis. These water-level records: (1) provide an index to available ground-water supplies;...
Geologic reconnaissance of possible powersites at Spur Mountain, Tyee, and Eagle lakes, southeastern Alaska
James E. Callahan, Alexander Andrew Wanek
1967, Open-File Report 67-35
Spur Mountain, Tyee, and Eagle Lakes fill glacially scoured bedrock basins in the Coast Range of southeastern Alaska. The bedrock consists of granitic intrusive rocks and high rank metamorphic rocks associated with or resulting from emplacement of the Coast Range batholith.Spur Mountain damsite is underlain by granodiorite and diorite. The...
Ground-water aspects of the lower Henrys Fork region, Idaho
E.J. Crosthwaite, M.J. Mundorff, E.H. Walker
1967, Open-File Report 67-71
The lower Henrys Fork region includes the plains and low benches between Ashton and the junction of Henrys Fork and Snake River in eastern Idaho. The northwestern and western parts of the area are part of the Snake River lava plain. The central part of the area is occupied by...
Preliminary report on the geology, geophysics and hydrology of USBM/AEC Colorado core hole No. 2, Piceance Creek Basin, Rio Blanco County, Colorado
J. R. Ege, R. D. Carroll, F.A. Welder
1967, Open-File Report 67-87
Approximately 1,400 feet of continuous core was taken .between 800-2,214 feet in depth from USBM/AEC Colorado core hole No. 2. The drill, site is located in the Piceance Creek basin, Rio Blanco County, Colorado. From ground surface the drill hole penetrated 1,120 feet of the Evacuation Creek Member and 1,094...
