Estimated average annual ground-water pumpage in the Portland Basin, Oregon and Washington 1987-88
C. A. Collins, T.M. Broad
1993, Water-Resources Investigations Report 91-4018
Data for ground-water pumpage were collected during an inventory of wells in 1987-88 in the Portland Basin located in northwestern Oregon and southwestern Washington. Estimates of annual ground-water pumpage were made for the three major categories of use: public supply, industry, and irrigation. A large rapidly expanding metropolitan area is...
Geohydrology and water quality of the Calumet aquifer, in the vicinity of the Grand Calumet River/Indiana Harbor Canal, northwestern Indiana
J.M. Fenelon, Lee R. Watson
1993, Water-Resources Investigations Report 92-4115
The water-table configuration of the Calumet aquifer in the vicinity of the Grand Calumet River/Indiana Harbor Canal in Lake County, northwestern Indiana, reflects the complexity of the shallow ground-water-flow system. Large depressions in the water table in sewered areas interrupt broad ground-water divides between rivers. The aquifer/stream interactions along the...
Hydrogeology, geochemistry, and quality of water of The Basin and Oak Spring areas of the Chisos Mountains, Big Bend National Park, Texas
E. T. Baker Jr., P.M. Buszka
1993, Water-Resources Investigations Report 93-4112
Test drilling near two sewage lagoons in The Basin area of the Chisos Mountains, Big Bend National Park, Texas, has shown that the alluvium and colluvium on which the lagoons are located is not saturated in the immediate vicinity of the lagoons. A shallow aquifer, therefore, does not exist in...
Geohydrology and quality of shallow ground water at and near the Old Laurel County and G.C. Singleton landfills, Laurel County, Kentucky
J. M. Parnell
1993, Water-Resources Investigations Report 93-4005
Between 1969 and 1983, solid and hazardous waste was deposited at the Old Laurel County and G.C. Singleton Landfills that were developed on a bench created by strip mining for coal. Water-level data from eight monitoring wells indicate that the general direction of groundwater flow in the shallow aquifer is...
Hydraulic properties of the Madison aquifer system in the western Rapid City area, South Dakota
Earl A. Greene
1993, Water-Resources Investigations Report 93-4008
Available information on hydrogeology, data from borehole geophysical logs, and aquifer tests were used to determine the hydraulic properties of the Madison aquifer. From aquifer-test analysis, transmissivity and storage coefficient were determined for the Minnelusa and Madison aquifers, and vertical hydraulic conductivity (Kv') along with specific storage (Ss') for the...
Hydrogeology, ground-water quality, and potential for water-supply contamination near an abandoned wood-preserving plant site at Jackson, Tennessee
W. S. Parks, J. E. Mirecki, J.A. Kingsbury
1993, Water-Resources Investigations Report 93-4170
Hydrogeologic and ground-water-quality data were collected near an abandoned wood-preserving plant site at Jackson, Tennessee to determine the extent and magnitude of ground-water contamination in offsite areas and to assess the potential for contamination of nearby water-supply wells. New methods were used to collect ground-water samples from the alluvial aquifer...
Reconnaissance investigation of the geology and hydrogeology of Lackland Air Force Base, San Antonio, Texas
G. B. Ozuna, T. A. Small
1993, Water-Resources Investigations Report 93-4037
An investigation at Lackland Air Force Base and Lackland Air Force Base Training Annex (Medina Base) was conducted from May to September 1988 to delineate the subsurface geology, to describe the hydrogeology within the study area, and to determine possible migration pathways for contaminants. Data from this investigation supplement data...
Method for predicting water demand for crop uses in New Jersey in 1990, 2000, 2010, and 2020, and for estimating water use for livestock and selected sectors of the food-processing industry in New Jersey in 1987
R.M. Clawges, E.O. Titus
1993, Water-Resources Investigations Report 92-4145
A method was developed to predict water demand for crop uses in New Jersey. A separate method was developed to estimate water use for livestock and selected sectors of the food-processing industry in 1987. Predictions of water demand for field- grown crops in New Jersey were made for...
Application of ground-penetrating radar methods in determining hydrogeologic conditions in a karst area, west-central Florida
G. L. Barr
1993, Water-Resources Investigations Report 92-4141
Ground-penetrating radar (GPR) is useful as a surface geophysical method for exploring geology and subsurface features in karst settings. Interpretation of GPR data was used to infer lithology and hydrogeologic conditions in west-central Florida. This study demonstrates how GPR methods can be used to investigate the hydrogeology of an area....
Hydrology and water chemistry of shallow aquifers along the upper Clark Fork, western Montana
D. A. Nimick
1993, Water-Resources Investigations Report 93-4052
Shallow ground-water resources in western Montana have been developed primarily in Quaternary alluvium and Tertiary deposits, although bedrock supplies water to wells locally. Well-yield and trans- missivity values were largest (medians of 40 gallons per minute and 970 feet squared per day, respec- tively) in alluvium and smallest (medians of...
Revised potentiometric-surface map, Yucca Mountain and vicinity, Nevada
E. M. Ervin, R. R. Luckey, D.J. Burkhardt
1993, Water-Resources Investigations Report 93-4000
The revised potentiometric-surface map presented in this report updates earlier maps of the Yucca Mountain area using mainly 1988 average water levels. Because of refinements in the corrections to the water-level measurements, these water levels have increased accuracy and precision over older values. The small-gradient area to the southeast of...
Geohydrology of the Mesilla ground-water basin, Dona Ana County, New Mexico, and El Paso County, Texas
E. L. Nickerson, R. G. Myers
1993, Water-Resources Investigations Report 92-4156
The aquifer system of the Mesilla ground-water basin is the Quaternary flood-plain alluvium and the Quaternary and Tertiary Santa Fe Group. The hydraulic gradient in the shallow flood-plain alluvium within the Mesilla Valley is generally between 4 and 6 feet per mile. The hydraulic gradient in the Santa Fe Group...
Statistical summaries of streamflow data for selected gaging stations on and near the Idaho National Engineering Laboratory, Idaho, through September 1990
M. A. J. Stone, Larry J. Mann, L.C. Kjelstrom
1993, Water-Resources Investigations Report 92-4196
Statistical summaries and graphs of streamflow data were prepared for 13 gaging stations with 5 or more years of continuous record on and near the Idaho National Engineering Laboratory. Statistical summaries of streamflow data for the Big and Little Lost Rivers and Birch Creek were analyzed as a requisite for...
Development, calibration, and testing of ground-water flow models for the Mississippi River Valley alluvial aquifer in eastern Arkansas using one-square-mile cells
G.L. Mahon, D.T. Poynter
1993, Water-Resources Investigations Report 92-4106
Significant water-level declines in the Mississippi River Valley alluvial aquifer prompted the need to better understand the flow system in the aquifer which, in turn, led to the development of digital groundwater flow models of the alluvial aquifer. Two models were developed in the eastern Arkansas study area with the...
