Thomas W. Dibblee Jr.
1967, Professional Paper 522
This report and map represent part of a geologic investigation by the U.S. Geological Survey of the known and potential deposits of borate minerals in the southern California desert regions. The primary purpose of this report and the geologic map (pl. 1) is to provide a geologic background for the...

Geology and ground-water resources of Laramie County, Wyoming
Marlin E. Lowry, Marvin A. Crist, John R. Tilstra
1967, Water Supply Paper 1834
Laramie County, an area of 2,709 square miles, is in the southeast corner of Wyoming. Rocks exposed there range in age from Precambrian to Recent. The most extensive aquifers in the county are the White River Formation of Oligocene age, which is as much as 500 feet thick and consists...
Chemical quality of surface water in the Allegheny River basin, Pennsylvania and New York
Edward F. McCarren
1967, Water Supply Paper 1835
The Allegheny River is the principal source of water to many industries and to communities in the upper Ohio River Valley. The river and its many tributaries pass through 19 counties in northwestern and western Pennsylvania. The population in these counties exceeds 3 million. A major user of the Allegheny...

Flood information for flood-plain planning
Conrad D. Bue
1967, Circular 539
Floods are natural and normal phenomena. They are catastrophic simply because man occupies the flood plain, the highwater channel of a river. Man occupies flood plains because it is convenient and profitable to do so, but he must purchase his occupancy at a price-either sustain flood damage, or provide flood-control...
Distribution of gold, tellurium, silver, and mercury in part of the Cripple Creek district, Colorado
Garland Bayard Gott, J. H. McCarthy, G.H. Van Sickle, J. B. McHugh
1967, Circular 543
Geochemical exploration studies were undertaken in the Cripple Creek district to test the possibility that large low-grade gold deposits might be found. Surface rock samples taken throughout the district indicate that the volcanic rocks between the productive veins contain an average of about 0.6 ppm (part per million) gold. In...

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....
