Laboratory safety handbook
E.L. Skinner, C.A. Watterson, J.C. Chemerys
1983, Open-File Report 83-131
Safety, defined as 'freedom from danger, risk, or injury,' is difficult to achieve in a laboratory environment. Inherent dangers, associated with water analysis and research laboratories where hazardous samples, materials, and equipment are used, must be minimized to protect workers, buildings, and equipment. Managers, supervisors, analysts, and laboratory support personnel...
Electrical and magnetic properties of rock and soil
J. H. Scott
1983, Open-File Report 83-915
Field and laboratory measurements have been made to determine the electrical conductivity, dielectric constant, and magnetic permeability of rock and soil in areas of interest in studies of electromagnetic pulse propagation. Conductivity is determined by making field measurements of apparent resisitivity at very low frequencies (0-20 cps), and interpreting the...
Water-resources investigations of the U.S. Geological Survey in Kansas; fiscal years 1981 and 1982
J. F. Kenny, L. J. Combs
1983, Open-File Report 83-932
One of the primary missions of the U.S. Geological Survey in Kansas is to investigate the occurrence, quantity, quality, distribution, and movement of surface and groundwater throughout the State. Primary activities include the systematic collection, analysis, and interpretation of hydrologic data, evaluation of water demands, and water-resources research. Hydrologic investigations...
The environmental history and present condition of Saudi Arabia's northern sand seas
John W. Whitney, D.J. Faulkender, Meyer Rubin
1983, Open-File Report 83-749
Saudi Arabia's northern sand seas are composed dominantly of stable dune systems, even though the modern climate is arid. The stable dunes are large and support a sparse semidesert vegetation. Active dunes are small and commonly confined to the crests of stable dunes; they comprise less than 5 percent of...
Stratigraphy, structure, and some petrographic features of Tertiary volcanic rocks at the USW G-2 drill hole, Yucca Mountain, Nye County, Nevada
Florian Maldonado, S. L. Koether
1983, Open-File Report 83-732
A continuously cored drill hole designated as USW G-2, located at Yucca Mountain in southwestern Nevada, penetrated 1830.6 m of Tertiary volcanic strata composed of abundant silicic ash-flow tuffs, minor lava and flow breccias, and subordinate volcaniclastic rocks. The volcanic strata penetrated are comprised of the following in descending order:...
Water resources in the Blackstone River basin, Massachusetts
Eugene H. Walker, Bruce E. Krejmas
1983, Open-File Report 83-700
The Blackstone River heads in brooks 6 miles northwest of Worcester and drains about 330 square miles of central Massachusetts before crossing into Rhode Island at Woonsocket. The primary source of the Worcester water supply is reservoirs, but for the remaining 23 communities in the basin, the primary source is wells. Bedrock...
In situ geomechanics of crystalline and sedimentary rocks; Part IV, continued field testing of the modified U.S. Geological Survey 3-D borehole stress probe
Thomas C. Nichols
1983, Open-File Report 83-750
Two modified and calibrated U.S. Geological Survey 3-D borehole probes were successfully tested in the field at a site on South Table Mountain, near Golden, Colo. The probes were installed in separate core holes at depths of 84 and 99 cm in the latite cap rock and subsequently stress relieved...
Paleomagnetic results from seven middle Paleozoic plutons in the Appalachian Piedmont of North and South Carolina
J.T. Hagstrum
1983, Open-File Report 83-916
Seven isotopically dated plutons of similar middle Paleozoic age (approx. 400 Ma) were sampled for paleomagnetic study. The results from 12 sites (152 samples) within these plutons show two types of remanence behavior that appear fairly consistent with rock composition. The more leucocratic rocks (9 sites) tend to yield single-component...
Streamflow and water-quality data for lake and wetland inflows and outflows in the Twin Cities metropolitan area, Minnesota, 1981-82
Luanne Nelson, R. G. Brown
1983, Open-File Report 83-543
A study of runoff to selected lakes was done in the Twin Cities metropolitan area from July 1981 to December 1982. The purpose of the study was to determine differences in nutrient-loading characteristics for lakes with and without wetlands and settling ponds. The study also quantified nutrient loading to lakes...
Data for ground-water studies of the San Juan Basin, New Mexico (1982-83)
R.L. Klausing, G. E. Welder
1983, Open-File Report 84-135
Ground-water data that can be used for futher hydrologic studies in the San Juan structural basin of New Mexico are reported. Descriptions and a location map of 64 observation wells, a list of water levels measured in the observation wells, water-level hydrographs of 32 wells, 15 partial chemical analyses of...
The effects of water content and water resistivity on the dispersion of resistivity and dielectric constant in quartz sand in the frequency range 10^2 to 10^8 Hz
W.R. Eberle
1983, Open-File Report 83-914
Using modifications of previously developed methods, measurements were made of the resistivity and the dielectric constant of two similar quartz sands of different porosity over the frequency range 102-108 Hertz for various water contents and water resistivities. Dispersion is pronounced in all the resistivity data above 106 Hz. As water...
