Annual variations in chemical composition of atmospheric precipitation, eastern North Carolina and southeastern Virginia
Donald W. Fisher
1967, Water Supply Paper 1535-M
A 2-year study of precipitation composition over eastern North Carolina and southeastern Virginia has been completed. Chemical analyses were made of the major ions in monthly rainfall samples from each of 12 sampling locations. Areal and seasonal distributions were determined for chloride, calcium, magnesium, sodium, potassium, sulfate, and nitrate. Annual...
Ground-water resources of the Pascagoula River basin, Mississippi and Alabama
Roy Newcome
1967, Water Supply Paper 1839-K
Abundant ground-water resources underlie the Pascagoula River basin. These resources have been developed intensively in only a few places--namely, Hattiesburg, Laurel, Meridian, and Pascagoula. Seepage from the ground water reservoirs sustains the base flows of the Leaf, Chickasawhay, Pascagoula, and Escatawpa Rivers and their tributaries. The fresh-water-bearing section is 300...
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...
Availability of ground water in York County, Nebraska
Charles Franklin Keech, V. H. Dreeszen, Philip A. Emery
1967, Water Supply Paper 1839-F
York County, an area of 575 square miles, is situated on an upland plain in southeast Nebraska. Although tributaries of the Big Blue River have eroded valleys into this plain, much of the original surface is still intact and is characterized by broad shallow undrained depressions. The economy is based...
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....
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...
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...
Ground-water conditions and geologic reconnaissance of the Upper Sevier River basin, Utah
Carl H. Carpenter, Gerald B. Robinson, Louis Jay Bjorklund
1967, Water Supply Paper 1836
The upper Sevier River basin is in south-central Utah and includes an area of about 2,400 .square miles of high plateaus and valleys. It comprises the entire Sevier River drainage basin above Kingston, including the East Fork Sevier River and its tributaries. The basin was investigated to determine general ground-water...
Evaluation of seepage from Chester Morse Lake and Masonry Pool, King County, Washington
F.T. Hidaka, Arthur Angus Garrett
1967, Water Supply Paper 1839-J
Hydrologic data collected in the Cedar and Snoqualmie River basins on the west slope of the Cascade Range have been analyzed to determine the amount of water lost by seepage from Chester Morse Lake and Masonry Pool and the. consequent gain by seepage to the Cedar and South Fork Snoqualmie...
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...
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...
Roughness characteristics of natural channels
Harry Hawthorne Barnes
1967, Water Supply Paper 1849
Color photographs and descriptive data are presented for 50 stream channels for which roughness coefficients have been determined. All hydraulic computations involving flow in open channels require an evaluation of the roughness characteristics of the channel. In the absence of a satisfactory quantitative procedure this evaluation remains chiefly an art....
Ground water in the Eola-Amity Hills area, northern Willamette Valley, Oregon
Don Price
1967, Water Supply Paper 1847
The Eola-Amity Hills area ,comprises about 230 square miles on the west side of the Willamette Valley between Salem and McMinnville, Oreg. The area is largely rural, and agriculture is the principal occupation. Rocks ranging in age from Eocene to Recent underlie the area. The oldest rocks are a sequence...
