Preliminary map showing availability of water from glacial-drift aquifers in McHenry County, north-central North Dakota
P.G. Randich
1980, Open-File Report 80-562
This preliminary map is the first product of the ground-water resources study of McHenry County.  This study is part of a statewide program to determine the location, extent, chemical quality, and hydrologic characteristics of the ground-water reservoirs (aquifers) in North Dakota.  The study was made by the U.S. Geological Survey in...
Results of water quality sampling near Richton, Cypress Creek and Lampton salt domes, Mississippi
L. A. Gandl, C. A. Spiers
1980, Open-File Report 80-443
In the Mississippi salt basin in southern Mississippi, chemical quality studies of surface water and ground water have been made to determine present water-quality conditions near three salt domes being studied by the Department of Energy as potential repositories for radioactive wastes. Chloride concentrations in excess of 60 milligrams per...
Rapid and precise determination of ATP using a modified photometer
David J. Shultz, Doyle W. Stephens
1980, Open-File Report 80-1194
An inexpensive delay timer was designed to modify a commercially available ATP photometer which allows a disposable tip pipette to be used for injecting either enzyme or sample into the reaction cuvette. The disposable tip pipette is as precise and accurate as a fixed-needle syringe but eliminates the problem of...
Low-flow characteristics of streams in the St. Croix River basin, Wisconsin
B. K. Holmstrom
1980, Open-File Report 80-696
Low-flow characteristics of streams in the St. Croix River basin , Wisconsin, are presented. Included are estimates of low-flow frequency and flow duration at 7 gaging stations, low-flow frequency characteristics at 23 low-flow partial-record stations and 78 miscellaneous sites, and a list of base-flow discharge measurements at 29 miscellaneous sites....
Thermal springs in the Payette River basin, west-central Idaho
R.E. Lewis, H.W. Young
1980, Open-File Report 80-1020
The Payette River basin, characterized by steep, rugged mountains and narrow river valleys, occupies an area of about 3 ,300 square miles in west-central Idaho. Predominant rock types in the basin include granitic rocks of the Idaho batholith and basalt flows of the Columbia River Basalt Group. Waters from thermal...
Examples of the use of earth-science information by decisionmakers in the San Francisco Bay region, California
W. J. Kockelman
1980, Open-File Report 80-124
In the six examples discussed and illustrated here, innovative decisionmakers -- public and private -- have used earth-science information to avoid areas with geologic hazards, protect natural resources, and reduce possible property damage in the San Francisco Bay region. The examples show how: 1) development in fault-rupture areas is regulated,...
