Hydrogeologic and water-quality characteristics of the St. Peter aquifer, Southeast Minnesota
J. F. Ruhl, R. J. Wolf
1983, Water-Resources Investigations Report 83-4200
Quality of water in the St. Peter aquifer is generally acceptable for most uses. Sulfate concentrations increase toward the southwestern part of the aquifer because of highly mineralized leakage from overlying Cretaceous deposits. Concentrations of sodium, magnesium, and sulfate generally increase to the west, and those of calcium, bicarbonate, and...
Evaluation of the effects of Lake Audubon on ground- and surface-water levels in the Lake Nettie area, eastern McLean County, North Dakota
C. A. Armstrong
1983, Water-Resources Investigations Report 83-4242
Water logging and flooding of some roads and agricultural lands have become a problem in the Lake Nettie area of eastern McLean County. Part of the flooding is caused by the raising of Lake Audubon about 13 feet from an elevation of about 1,835 feet to 1,848 feet and its...

George W. Hawkins, Gregory M. Terlecki
1983, Open-File Report 82-568
The population of central and eastern Long Island, New York depends on ground water for its supply of fresh water. Data on more than 7,500 wells on the island have been collected by various State and local agencies and compiled by the U.S. Geological Survey since 1906. During 1975-81, the...
Regional magnetic and gravity features of the Gibson Dome area and surrounding region, Paradox Basin, Utah: A preliminary report
T.G. Hildenbrand, R.P. Kucks
1983, Open-File Report 83-359
Analyses of regional gravity and magnetic anomaly maps have been carried out to assist in the evaluation of the Gibson Dome area as a possible repository site for high-level radioactive waste. Derivative, wavelength-filtered, and trend maps were compiled to aid in properly locating major geophysical trends corresponding to faults, folds,...
A two-dimensional, finite-difference model of the high plains aquifer in southern South Dakota
K.E. Kolm, H. L. Case III
1983, Water-Resources Investigations Report 83-4175
The High Plains aquifer is the principal source of water for irrigation, industry, municipalities, and domestic use in south-central South Dakota. The aquifer, composed of upper sandstone units of the Arikaree Formation, and the overlying Ogallala and Sand Hills Formations, was simulated using a two-dimensional, finite-difference computer model. The maximum...
