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...
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...
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...
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...
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...
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...
Iron in the United States, exclusive of Alaska and Hawaii
Martha S. Carr, Philip White Guild, W.B. Wright
1967, Mineral Investigations Resource Map 51
The iron-ore deposits in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map; many iron-bearing deposits that are of lesser or only potential value are also shown. Because these deposits range widely in extent, two general categories of symbols are used, each of which is...
A photo-mosaic of western Peru from Gemini photography
J. A. MacKallor
1967, Open-File Report 67-150
The Geological Survey in cooperation with the National Aeronautics and Space Administration and with the Raytheon Company has prepared a mosaic from photographs taken during the Gemini IX mission. The 1:1,000,000-scale photo-mosaic extends from the Sechura Desert in northern Peru to northern Chile and from the Pacific Ocean to the...
Historic surface faulting in continental United States and adjacent parts of Mexico
M. G. Bonilla
1967, Open-File Report 67-23
This report summarizes geometric aspects of approximately 35 instances of historic faulting of the ground surface in the continental United States and adjacent parts of Mexico. This information is of immediate importance in the selection and evaluation of sites for vital structures such as nuclear power plants. The data are...
Delaware River basin - water data stations, 1967
D.W. Moody, F.L. Shaefer
1967, Open-File Report 67-160
This report presents information on station-type activities for acquiring surface-water, ground-water, and quality of water data in the Delaware River basin. The information was collected in 1966 through field offices of the Water Resources Division, U.S. Geological Survey as part of a pilot study for the Office of Water Data...
Discovery of phosphate rock in Saudi Arabia and recommended program of further study
Richard Porter Sheldon
1967, Open-File Report 67-199
In the period August 12, to September 3, 1965, I was assigned as a phosphate specialist to the U.S. Geological Survey Group in Saudi Arabia to work in cooperation with the Ministry of Petroleum and Mineral Resources of the Saudi Arabian Government.  My assignment was to evaluate the phosphate potential...
