Precision and bias of selected analytes reported by the National Atmospheric Deposition Program and National Trends Network, 1983; and January 1980 through September 1984
L.J. Schroder, A.W. Bricker, T. C. Willoughby
1985, Water-Resources Investigations Report 85-4275
Blind-audit samples with known analyte concentrations have been prepared by the U.S. Geological Survey and distributed to the National Atmospheric Deposition Program 's Central Analytical Laboratory. The difference between the National Atmospheric Deposition Program and National Trends Network reported analyte concentrations and known analyte concentrations have been calculated, and the...
Hydrology of the alluvial, buried channel, basal Pleistocene and Dakota aquifers in west-central Iowa
D. L. Runkle
1985, Water-Resources Investigations Report 85-4239
A ground-water resources investigation in west-central Iowa indicates that water is available from alluvial, buried channel, basal Pleistocene, and Dakota aquifers. The west-central Iowa area includes Audubon, Carrol1, Crawford, Greene, Guthrie, Harrison, Monona, and Shelby Counties. Nine alluvial aquifers consisting of sand and gravel are in the valleys of the Little...
Operation of hydrologic data collection stations by the U.S. Geological Survey in 1985
Alberto Condes de la Torre
1985, Open-File Report 85-640
The U.S. Geological Survey (USGS) operated hydrologic data collection stations during fiscal yr 1985 in response to the needs of all levels of Government for hydrologic information. Surface water discharge was determined at 11,076 stations; stage data on streams, reservoirs, and lakes were recorded at 2,141 stations; and surface water...
Simulated effects of projected pumping on the availability of freshwater in the Evangeline Aquifer in an area southwest of Corpus Christi, Texas
George E. Groschen
1985, Water-Resources Investigations Report 85-4182
This study is an investigation of the continued availability of freshwater in the Evangeline aquifer along the Texas Gulf Coast and the potential for degradation of the water quality by salinewater intrusion. Recharge to the aquifer occurs by the infiltration of precipitation in the outcrop area and by cross-formational flow...
