Hydrologic maps of the High Plains aquifer, January 1981, southwestern Kansas
Joseph M. Spinazola
1982, Water-Resources Investigations Report 82-4079
The U.S. Geological Survey furnishes maps depicting saturated thickness of the High Plains aquifer to the Southwest Kansas Groundwater Management District No. 3 through a continuing cooperative agreement.  The Groundwater Management District uses the maps to calculated a planned depletion rate of 40 percent of the saturated thickness of the...
Methods for the determination of organic substances in water and fluvial sediments, USGS TWRI, Book 5, Laboratory analysis, Chapter A3
Robert L. Wershaw, Marvin J. Fishman, R. R. Grabbe, L. E. Lowe, editor(s)
1982, Open-File Report 82-1004
This manual contains analytical methods used by the U.S. Geological Survey for the determination of organic substances in water, water-suspended sediment mixtures, and bottom material. Some of the analytical procedures yield determinations for specific compounds, whereas others provide a measure of the quantity of groups of compounds present in the...
Percentage change in saturated thickness of the High Plains Aquifer, west-central Kansas, 1950 to average 1980-82
Marilyn E. Pabst
1982, Open-File Report 82-1010
A statistical technique, called kriging, was programmed for a computer to interpolate hydrologic data based on a network of 296 measured values in west-central Kansas and eastern Colorado. The computer program generated estimated values of selected hydrologic data at the center of each 1-mile section in the Western Kansas Groundwater...
Water resources data for Florida, water year 1981; Volume 1. Northeast Florida
Water Resources Division, U.S. Geological Survey
1982, Water Data Report FL-81-1
Water resources data for the 1981 water year for northeast Florida consist of records of stage, discharge, and water quality of streams; elevation and water quality of lakes and reservoirs; water levels and water quality of wells; and discharge and water quality of springs. Additional water data were collected at...
Map showing how the potentiometric surface of the Magothy Aquifer of August 1980 differed from the potentiometric surface of September 1977, in southern Maryland
Frederick K. Mack Jr., J. C. Wheeler, Stephen E. Curtin
1982, Open-File Report 81-631
The map is based on the differences between two sets of water-level measurements made in 65 observation wells. One set was made in 1977, a relatively dry year, and the other set was made in 1980, another relatively dry year. The map shows that the potentiometric surface was higher in...
Water resources data for Connecticut, water year 1981
Water Resources Division, U.S. Geological Survey
1982, Water Data Report CT-81-1
Water resources data for the 1981 water year for Connecticut consist of records of stage, discharge, and water quality of streams; contents and water quality of lakes and reservoirs; and water levels and water quality of ground-water wells. This volume contains records for water discharge at 55 gaging stations; storm...
Origin of intraformational folds in the Jurassic Todilto Limestone, Ambrosia Lake uranium mining district, McKinley and Valencia counties, New Mexico
M. W. Green
1982, Open-File Report 82-69
The Todilto Limestone of Middle Jurassic age in the Ambrosia Lake uranium mining district of McKinley and Valencia Counties, New Mexico, is the host formation for numerous small- to medium-sized uranium deposits in joints, shear zones, and fractures within small- to large-scale intraformational folds. The folds probably were formed as...
Use of geophysical logs in recognizing depositional environments in the Tongue River Member of the Fort Union Formation, Powder River area, Wyoming and Montana
R. M. Flores, J.C. Toth, T.A. Moore
1982, Open-File Report 82-576
The environmental conditions under which rocks in the Paleocene Tongue River Member of the Fort Union Formation were deposited in the Powder River area, Wyoming and Montana, can be determined using geophysical logs with some limitations. It is widely recognized that gamma ray and density logs are useful in identifying...
The lanthanides and yttrium in minerals of the apatite group; a review
Michael Fleischer, Z. S. Altschuler
1982, Open-File Report 82-783
More than 1000 analyses have been tabulated of the distribution of the lanthanides and yttrium in minerals of the apatite group, recalculated to atomic percentages. Average compositions have been calculated for apatites from 14 types of rocks. These show a progressive change of composition from apatites of granitic pegmatites, highest...
Appraisal of the Pelican River sand-plain aquifer, western Minnesota
R. T. Miller
1982, Open-File Report 82-347
The Pelican River sand-plain area includes approximately 200 square miles of outwash deposits in parts of Decker, Otter Tail, and Clay Counties in west-central Minnesota. Saturated thickness of the outwash is as much as 140 feet and yields of properly constructed wells locally may exceed 1,200 gallons per minute. Recharge to...
