Hydrogeology and ground-water-quality conditions at the Geary County landfill, northeast Kansas, 1988
N. C. Myers, P. R. Bigsby
1989, Water-Resources Investigations Report 89-4114
Chemical analysis of water from monitoring wells upgradient and downgradient of the Geary County Landfill in Kansas near Junction City indicate the presence of several chemically distinct water types. For the dominant calcium bicarbonate water type, concentrations of inorganic and organic constituents indicate the presence of reducing conditions within the...
Streamflow, sediment discharge, and streambank erosion in Cache Creek, Yolo County, California, 1953-86
J.G. Harmon
1989, Water-Resources Investigations Report 88-4188
This report defines cross-section geometry, slope, sinuosity, bed and bank material size, and sediment discharge for Cache Creek, Capay Valley, Yolo County, California; it also relates streambank erosion to daily volumes of flow greater than 6,000 acre-ft. Mean bed elevations at six cross sections during 1983-86 and at two cross...
Estimates of mean monthly streamflow for selected sites in the Musselshell River basin, Montana, base period water years 1937-86
Charles Parrett, D.R. Johnson
1989, Water-Resources Investigations Report 89-4165
Estimates of mean monthly and mean annual streamflow were made for 56 selected sites in the Musselshell River basin and 1 site outside the basin. The study area was divided into a Mountain Region and a Plains Region and the estimation methods were applied separately in the two regions. Four...
Estimated use of water in Colorado, 1985
D. W. Litke, C. L. Appel
1989, Water-Resources Investigations Report 88-4101
Water-use data was collected for the State of Colorado as part of the U.S. Geological Survey 's National Water-Use Information Program. An estimated 20,800 million gal/day of water were used in Colorado during 1985. 89% came from surface water sources and 11% came from groundwater sources. Public supply systems provided...
Analysis of the effect of pumping on ground-water flow in the Springfield Plateau and Ozark aquifers near Springfield, Missouri
J. L. Imes
1989, Water-Resources Investigations Report 89-4079
Pumpage of water from the Ozark aquifer for public supply and industry use by the city of Springfield and surrounding communities in southwestern Missouri has significantly altered the potentiometric surface of the aquifer. Springfield is located on a regional groundwater divide that trends east and west across southern Missouri. Groundwater...
Test holes for monitoring surface-water/ground-water relations in the Cottonwood Creek area, Shasta and Tehama Counties, California, 1984-85
M. J. Johnson, E.R. Houston, J. M. Neil
1989, Water-Resources Investigations Report 88-4090
Ten test holes were drilled to obtain hydrogeologic information for an investigation of stream-aquifer interaction near proposed damsites on Cottonwood Creek and South Fork Cottonwood Creek, California. At each site, one deep well was completed below the first confining clay encountered in the upper Tehama Formation to determine hydraulic gradients...
Geohydrologic aspects for siting and design of low-level radioactive-waste disposal
M. S. Bedinger
1989, Circular 1034
The objective for siting and design of low-level radioactive-waste repository sites is to isolate the waste from the biosphere until the waste no longer poses an unacceptable hazard as a result of radioactive decay. Low-level radioactive waste commonly is isolated at shallow depths with various engineered features to stabilize the...
Peak-flow characteristics of small urban drainages along the Wasatch Front, Utah
K.L. Lindskov, K. R. Thompson
1989, Water-Resources Investigations Report 89-4095
Designers and planners for local, State, and Federal agencies need up-to- date methods for determining peak-flow characteristics for urban drainages along the Wasatch Front, Utah. This report summarizes methods used to develop equations that estimate peak-flows for small urban drainages along the Wasatch Front. Mathematical equations were developed that estimate...
Withdrawals and consumptive use of water in Pennsylvania, 1984
C. A. Loper, S. D. Lent, K. L. Wetzel
1989, Water-Resources Investigations Report 88-4095
Total accountable water withdrawals in Pennsylvania during 1984 were 14,033.66 Mga/d (million gallons per day); of that total, 5.2 percent (729.53 Mgal/d) was supplied from ground-water sources in 94.8 percent (13,302.12 Mgal/d) was supplied from surface-water sources. Thermoelectric power generation accounted for 71 percent of the total withdrawals (10,010.60 Mgal/d);...
Aquifer-system compaction, Tucson Basin and Avra Valley, Arizona
R. T. Hanson
1989, Water-Resources Investigations Report 88-4172
Groundwater declines of several ft/yr since the 1940 's have induced aquifer-system compaction and land subsidence of as much as 0.5 ft in the Tucson basin and 1.1 ft in Avra Valley, Arizona. Aquifer system compaction is affected by the layering, hydraulic diffusivity, preconsolidation-stress threshold, and stress history of the...
Tritium concentrations in flow from selected springs that discharge to the Snake River, Twin Falls-Hagerman area, Idaho
L. J. Mann
1989, Water-Resources Investigations Report 89-4156
Concern has been expressed that some of the approximately 30,900 curies of tritium disposed to the Snake River Plain aquifer from 1952 to 1988 at the INEL (Idaho National Engineering Laboratory) have migrated to springs discharging to the Snake River in the Twin Falls-Hagerman area. To document tritium concentrations in...
Estimating pumping time and ground-water withdrawals using energy- consumption data
R. T. Hurr, D. W. Litke
1989, Water-Resources Investigations Report 89-4107
Evaluation of the hydrology of an aquifer requires knowledge about the volume of groundwater in storage and also about the volume of groundwater withdrawals. Totalizer flow meters may be installed at pumping plants to measure withdrawals; however, it generally is impractical to equip all pumping plants in an area with...
