Results of a reconnaissance water-quality sampling program of the Ogallala aquifer in Colorado, Kansas, Nebraska, Oklahoma, South Dakota, and Texas
Gerald L. Feder, Noel C. Krothe
1981, Water-Resources Investigations Report 81-65
Results of a reconnaissance water-quality sampling program of the Ogallala aquifer indicates the water generally is suitable for most uses. Fluoride and selenium were the only chemical constituents found to exceed the National Interim Primary Drinking Water Regulations in water from some of the wells.Unusually large silica concentrations in many...
Water resources data for Maine, water year 1980
Water Resources Division, U.S. Geological Survey
1981, Water Data Report ME-80-1
Water resources data for the 1980 water year for Maine consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of wells. This report contains discharge records for 61 gaging stations; stage only for 2 gaging...
The United States Geological Survey in Alaska: Accomplishments during 1979
Nairn Albert, Travis Hudson, editor(s)
1981, Circular 823-B
This circular describes the 1980 programs of the U.S. Geological Survey in Alaska. A brief description of the Alaskan operations of each major division of the Survey is followed by project descriptions arranged by geographic regions in which the work takes place. The mission of the Geological Survey is to...
Quality of water and time of travel in Goodwater and Okatoma Creeks near Magee, Mississippi
Stephen J. Kalkhoff
1981, Open-File Report 81-1012
An intensive quality-of-water study was conducted during a period of generally low streamflow in Goodwater and Okatoma Creeks near Magee, Miss. During the August 12-14, 1980, study, the mean specific conductance of the water at all sites was less than 59 micromhos per centimeter; the dissolved-oxygen concentrations were greater than...
Considerations for monitoring water quality of the Schenectady aquifer, Schenectady County, New York
R. V. Allen, Roger Milton Waller
1981, Water-Resources Investigations Report 80-103
Six public water-supply systems in Schenectady County, N.Y., obtain water from sand and gravel units that form a more or less continuous aquifer system contiguous to the Mohawk River. The aquifer is under water-table conditions and in hydraulic contact with the river, so that pumping wells induces recharge from the...
Infectious waterborne diseases
Phillip E. Greeson
1981, Circular 848-D
This is the third of several compilations of briefing papers on water quality by the U.S. Geological Survey. Each briefing paper is prepared in a simple, nontechnical, easy-to-understand manner. This U.S. Geological Survey Circular contains papers on selected organic substances in water. Briefing papers are included on ' Why study...
A model for simulation of flow in singular and interconnected channels
Raymond W. Schaffranek, R.A. Baltzer, D.E. Goldberg
1981, Techniques of Water-Resources Investigations 07-C3
A one-dimensional numerical model is presented for simulating the unsteady flow in singular riverine or estuarine reaches and in networks of reaches composed of interconnected channels. The model is both general and flexible in that it can be used to simulate a wide range of flow conditions for various channel...
