Analytical results and sample locality map of heavy-mineral-concentrate and rock samples from the Castle Peaks Wilderness Study Area (CDCA- 266), San Bernardino County, California
B. M. Adrian, J. G. Frisken, M.J. Malcolm, J.G. Crock
1986, Open-File Report 86-416
The report presents water-quality and geohydrologic information for 106 public water-supply wells in Illinois. These wells were sampled during April to December 1984 as part of a pilot program to develop a ground-water observation network in the State. The pilot program was designed to sample single-aquifer wells from three major...
Data on ground-water quality for the Millett 1° x 2° quadrangle, central Nevada
Alan H. Welch, Rhea P. Williams
1986, Open-File Report 85-648-A
Water quality data for groundwater were compiled for the Millett 1° x 2° quadrangle which covers a portion of central Nevada. Chemical characteristics of the water are shown on a map (at a scale of 1:250,000) and on trilinear diagrams for the major ions. The data for the area are...
Data uses and funding for the stream-gaging program in Utah
R.W. Cruff
1986, Open-File Report 86-51
This report documents the results of the first phase of a study of the cost effectiveness of the streamflow-information program in Utah. Data use, funding, and data availability are described for the streamflow stations operated by the U.S. Geological Survey; and a history of the stream-gaging program is given. During...
Application of the aerial profiling of terrain system
E.J. Cyran
1986, Open-File Report 86-2
Test well Ch-Bf 146 was drilled to 1,650 ft below land surface to explore and evaluate the Patapsco Formation aquifers deeper than 1,000 ft in the Waldorf/La Plata area of Charles County, Maryland. The test hole penetrated two major aquifer systems above a depth of 1,000 ft and another major...
Concepts and data-collection techniques used in a study of the unsaturated zone at a low-level radioactive-waste disposal site near Sheffield, Illinois
R. W. Healy, M.P. DeVries, Robert G. Striegl
1986, Water-Resources Investigations Report 85-4228
A study of water and radionuclide movement through the unsaturated zone is being conducted at the low level radioactive waste disposal site near Sheffield, Illinois. Included in the study are detailed investigations of evapotranspiration, movement of water through waste trench covers, and movement of water and radionuclides (dissolved and gaseous)...
The SALT NORM : a quantitative chemical-mineralogical characterization of natural waters
Marc W. Bodine Jr., Blair F. Jones
1986, Water-Resources Investigations Report 86-4086
The new computer program SNORM calculates the salt norm from the chemical composition of a natural water. The salt norm is the quantitative ideal equilibrium assemblage that would crystallize if the water evaporated to dryness at 25 C and 1 bar pressure under atmospheric partial pressure of CO2. SNORM proportions...
Rock riprap design for protection of stream channels near highway structures; Volume 1, Hydraulic characteristics of open channels
J. C. Blodgett
1986, Water-Resources Investigations Report 86-4127
Volume I discusses the hydraulic and channel properties of streams, based on data from several hundred sites. Streamflow and geomorphic data have been collected and developed to indicate the range in hydraulic factors typical of open channels , to assist design, maintenance, and construction engineers in preparing rock riprap bank...
