Development of ground-water supplies at Mississippi test facility, Hancock County, Mississippi
Roy Newcome
1967, Water Supply Paper 1839-H
Potable and industrial water supplies at the National Aeronautics and Space Administration's Mississippi Test Facility in Hancock County, Miss., are obtained from large-capacity wells that tap southward-dipping water-bearing sands of Miocene and Pliocene age. The fresh-water-bearing section is 2,000-3,000 feet thick in the area, and individual aquifers are as thick...
Geohydrology of the Souris River Valley in the vicinity of Minot, North Dakota
Wayne A. Pettyjohn
1967, Water Supply Paper 1844
The Minot area is in the north-central part of North Dakota and includes part of the Souris River valley. The region is covered by glacial drift of late Wisconsin age except in small areas where the Fort Union Formation of Tertiary age crops out. Thickness of the drift is controlled...
Summary of hydrologic and physical properties of rock and soil materials, as analyzed by the hydrologic laboratory of the U.S. Geological Survey, 1948-60
D. A. Morris, A.I. Johnson
1967, Water Supply Paper 1839-D
The Hydrologic Laboratory was established in 1948 to serve as the central testing laboratory for the Water Resources Division of the U.S. Geological Survey. Since then, thousands of samples of rock and soil materials have been analyzed in the laboratory. Analytical data on samples from 42 States and for the...
The breeding bird survey, 1966
Chandler S. Robbins, Willet T. Van Velzen
1967, Special Scientific Report - Wildlife 102
A Breeding Bird Survey of a large section on North America was conducted during June 1966. Cooperators ran a total of 585 Survey routes in 26 eastern States and 4 Canadian Provinces. Future coverage of established routes will enable changes in the abundance of North American breeding birds to be...
Geological Survey research 1967, Chapter B
Water Resources Division, U.S. Geological Survey
1967, Professional Paper 575-B
This collection of 49 short papers is the first published chapter of "Geological Survey Research 1967." The papers report on scientific and economic results of current work. by members of the Geologic, Topographic, and Water Resources Divisions of the U.S. Geological Survey....
Cenozoic Volcanic Rocks of the Devils Postpile Quadrangle, Eastern Sierra Nevada, California
N. King Huber, C. Dean Rinehart
1967, Professional Paper 554-D
Cenozoic volcanic rocks of the Devils Postpile quadrangle are of late Pliocene to Recent age and are divided into 11 map units. The suite is alkalic-calcic and ranges in composition from basalt to rhyolite. It includes a rhyolitic welded ash-flow tuff which is probably correlative with the Bishop Tuff, although...
Effect of the earthquake of March 27, 1964, on the Eklutna Hydroelectric Project, Anchorage, Alaska, with a section on television examination of earthquake damage to underground communication and electrical systems in Anchorage
Malcolm H. Logan, Lynn R. Burton
1967, Professional Paper 545-A
The March 27, 1964, Alaska earthquake and its associated aftershocks caused damage requiring several million dollars worth of repair to the Eklwtna Hydroelectric Project, 34 miles northeast of Anchorage. Electric service from the Eklutna powerplant was interrupted during the early phase of the March 27 earthquake, built was restored (intermittently)...
Swatara Creek basin of southeastern Pennsylvania: An evaluation of its hydrologic system
Wilbur Tennant Stuart, William J. Schneider, James W. Crooks
1967, Water Supply Paper 1829
Local concentrations of population in the Swatara Creek basin of Pennsylvania find it necessary to store, transport, and treat water because local supplies are either deficient or have been contaminated by disposal of wastes in upstream areas. Water in the basin is available for the deficient areas and for dilution...
Specific yield: compilation of specific yields for various materials
A.I. Johnson
1967, Water Supply Paper 1662-D
Specific yield is defined as the ratio of (1) the volume of water that a saturated rock or soil will yield by gravity to (2) the total volume of the rock or soft. Specific yield is usually expressed as a percentage. The value is not definitive, because the quantity of...
Reconnaissance of the chemical quality of surface waters of the Neches River basin, Texas
Leon S. Hughes, Donald K. Leifeste
1967, Water Supply Paper 1839-A
The kinds and quantities of minerals dissolved in the surface water of the Neches River basin result from such environmental factors as geology, streamflow patterns and characteristics, and industrial influences. As a result of high rainfall in the basin, much of the readily soluble material has been leached from the...
A simple mercury vapor detector for geochemical prospecting
William W. Vaughn
1967, Circular 540
The detector utilizes a large-volume atomic-absorption technique for quantitative determinations of mercury vapor thermally released from crushed rock. A quartz-enclosed noble-metal amalgamative stage, which is temperature controlled and is actuated by a radio-frequency induction heater, selectively traps the mercury and eliminates low-level contamination. As little as 1 part per billion...
