Hydrogeology and ground-water-quality conditions at the Emporia- Lyon County Landfill, eastern Kansas, 1988
N. C. Myers, P. R. Bigsby
1990, Water-Resources Investigations Report 90-4043
Hydrogeology and water-quality conditions at the Emporia-Lyon County Landfill, eastern Kansas, were investigated from April 1988 through April 1989. Potentiometric-surface maps indicated groundwater movement from the northeast and northwest towards the landfill and then south through the landfill to the Cottonwood River. The maps indicate that during periods of low...
Comparison of accuracy and completeness of data obtained from three types of automatic water-quality monitors
Max Katzenbach
1990, Water-Resources Investigations Report 89-4198
A comparison of data (specific conductance, dissolved-oxygen concentration, temperature, and pH) collected by the U.S. Geological Survey flowthrough monitor, the U.S. Geological Survey minimonitor, and a self-contained commercial 'packaged-sensor' system indicates that the data obtained by means of the most complete of the three systems. The U.S. Geological Survey flowthrough monitor...
Determination of hydraulic properties in the vicinity of a landfill near Antioch, Illinois
Robert T. Kay, John D. Earle
1990, Water-Resources Investigations Report 89-4124
A hydrogeologic investigation was conducted in and around a landfill near Antioch, Illinois, in December 1987. The investigation consisted, in part, of an aquifer test that was designed to determine the hydraulic connection between the hydrogeologic units in the area. The hydrogeologic units consist of a shallow, unconfined, sand and...
Geohydrology and water quality of confined-drift aquifers in the Brooten-Belgrade area, west-central Minnesota
G. N. Delin
1990, Water-Resources Investigations Report 88-4124
Confined-drift aquifers in six aquifer zones identified in a 1,300-square-mile area of west-central Minnesota near Brooten and Belgrade range in thickness from 5 to 110 feet. Transmissivities generally range from 500 to 10,000 feet squared per day, and theoretical well yields generally range from 100 to 900 gallons per minute. Regional...
Simulation of ground-water flow in the Prairie du Chien-Jordan and overlying aquifers near the Mississippi River, Fridley, Minnesota
R. J. Lindgren
1990, Water-Resources Investigations Report 90-4165
A three-dimensional, ground-water-flow model was developed to gain an improved understanding of the ground-water-flow system and its response to withdrawals near the Minneapolis Water Works in Fridley, Minnesota. Eight hydrogeologic units are represented in the ground-water-flow model. Aquifers represented are the unconfined-drift, confined-drift, St. Peter, and Prairie du Chien-Jordan. Confining...
PRECONDITIONED CONJUGATE-GRADIENT 2 (PCG2), a computer program for solving ground-water flow equations
Mary C. Hill
1990, Water-Resources Investigations Report 90-4048
This report documents PCG2 : a numerical code to be used with the U.S. Geological Survey modular three-dimensional, finite-difference, ground-water flow model . PCG2 uses the preconditioned conjugate-gradient method to solve the equations produced by the model for hydraulic head. Linear or nonlinear flow conditions may be simulated. PCG2 includes...
Simulation of ground-water flow in the St Peter aquifer in an area contaminated by coal-tar derivatives, St Louis Park, Minnesota
D. L. Lorenz, J. R. Stark
1990, Water-Resources Investigations Report 90-4150
A model constructed to simulate ground-water flow in part of the Prairie du Chien-Jordan and St. Peter aquifers, St. Louis Park, Minnesota, was used to test hypotheses about the movement of ground water contaminated with coal-tar derivatives and to simulate alternatives for reducing the downgradient movement of contamination in the...
Hydrology and land use in Grand Traverse County, Michigan
T. R. Cummings, J.L. Gillespie, N.G. Grannemann
1990, Water-Resources Investigations Report 90-4122
Glacial deposits are the sole source of ground-water supplies in Grand Traverse County. These deposits range in thickness from 100 to 900 feet and consist of till, outwash, and materials of lacustrine and eolian origin. In some areas, the deposits fill buried valleys that are 500 feet deep. Sedimentary rocks...
Gaged and estimated monthly streamflow during 1931-84 for selected sites in the Red River of the North basin in North Dakota and Minnesota
R. S. Guenthner, J. F. Weigel, D. G. Emerson
1990, Water-Resources Investigations Report 90-4167
Operation of the Garrison Diversion Unit in North Dakota may have various effects on the quantity and quality of streamflow in the Sheyenne River and the Red River of the North. To model the effects that the Garrison Diverson Unit could have on water quantity, monthly gaged and estimated streamflow...
Guidelines for collection and field analysis of water-quality samples from streams in Texas
F.C. Wells, W.J. Gibbons, M.E. Dorsey
1990, Open-File Report 90-127
This manual provides standardized guidelines and quality-control procedures for the collection and preservation of water-quality samples and defines procedures for making field analyses of unstable constituents or properties. Descriptions and procedures are given for several methods of sampling for which a variety of samplers may be used. Sample-processing devices such as...
Ground-water pumpage and water-level declines in the Peedee and Black Creek aquifers in Onslow and Jones counties, North Carolina, 1900-86
W.L. Lyke, A. R. Brockman
1990, Water-Resources Investigations Report 89-4197
Two aquifers in sediments of Cretaceous age, The Peedee and Black Creek aquifers, have become a major source of freshwater in Onslow and Jones Counties in North Carolina since about 1960. Prior to 1960, most water systems in this area withdrew water from younger sand or limestone beds that overlie...
Ground-water levels in the alluvial aquifer in eastern Arkansas, 1988
P.W. Westerfield, C.R. Baxter
1990, Open-File Report 90-383
This report, prepared by the U.S. Geological Survey in cooperation with the Arkansas Soil and Water Conservation Commission, the U.S. Soil Conservation Service, and local Conservation Districts, contains groundwater level measurements of 509 wells that tap the alluvial aquifer in the Quaternary deposits of the Mississippi Alluvial Plain. The measurements...
