Water resources of Taos County, New Mexico
Lynn A. Garrabrant
1993, Water-Resources Investigations Report 93-4107
In Taos County, ground water generally is unconfined and moves toward the Rio Grande or perennial streams. Water quality is good except in some areas where water has high values of specific conductance and hardness and contains high concentrations of dissolved solids and fluoride. Most wells are completed in alluvial...
Factors affecting areas contributing recharge to wells in shallow aquifers
Thomas E. Reilly, David W. Pollock
1993, Water Supply Paper 2412
The source of water to wells is ultimately the location where the water flowing to a well enters the boundary surface of the ground-water system. In ground-water systems that receive most of their water from areal recharge, the location of the water entering the ground-water system is at the water...
Water Resources Data, California, Water Year 1992. Volume 4. Northern Central Valley Basins and the Great Basin from Honey Lake Basin to Oregon State Line
S.W. Anderson, J.R. Mullen, M.F. Friebel, K.L. Markham
1993, Water Data Report CA-92-4
Water resources data for the 1992 water year for California consist of records of stage, discharge, and water quality of streams; stage and contents in lakes and reservoirs; and water levels and water quality in wells. Volume 4 contains discharge records for 190 gaging stations; stage and contents for 44...
Conceptual evaluation of regional ground-water flow in the carbonate-rock province of the Great Basin, Nevada, Utah, and adjacent states
David E. Prudic, J. R. Harrill, T. J. Burbey
1993, Open-File Report 93-170
The regional groundwater flow system in the carbonate rocks of Nevada and Utah is conceptualized as shallow systems superimposed on deeper systems, which transmit water primarily through carbonate rocks. A computer model was used to simulate the two systems. The regional model includes simplifying assumptions that are probably valid for...
Geochemistry of and radioactivity in ground water of the Highland Rim and Central Basin aquifer systems, Hickman and Maury counties, Tennessee
G. E. Hileman, R. W. Lee
1993, Water-Resources Investigations Report 92-4092
A reconnaissance of the geochemistry of and radioactivity in ground water from the Highland Rim and Central Basin aquifer systems in Hickman and Maury Counties, Tennessee, was conducted in 1989. Water in both aquifer systems typically is of the calcium or calcium magnesium bicarbonate type, but concentrations of calcium, magnesium,...
Biogeochemical and hydrological processes controlling the transport and fate of 1,2-dibromoethane (EDB) in soil and ground water, central Florida
Brian G. Katz
1993, Water Supply Paper 2402
Widespread contamination of ground water in central Florida by 1,2-dibromoethane (EDB) has resulted because of its heavy usage as a soil fumigant during a 20-year period, its relatively high aqueous solubility, and the low sorption capacity of the highly permeable sandy soils lacking organic matter. Two models were used to...
Data from core analyses, aquifer testing, and geophysical logging of Denver Basin bedrock aquifers at Castle Pines, Colorado
S. G. Robson, E. R. Banta
1993, Open-File Report 93-442
This report contains data pertaining to the geologic and hydrologic characteristics of the bedrock aquifers of the Denver basin at a site near Castle Pines, Colorado. Data consist of a lithologic- description of about 2,400 ft of drill core and laboratory determinations of mineralogy, grain size, bulk and grain density,...
Trends in offstream water use in Indiana, 1960-90
D.V. Arvin
1993, Open-File Report 93-452
Water-use data for Indiana from 1960 to 1990 were analyzed to determine general trends of offstream water use. Since 1960, total withdrawals have increased, although there have been periods of increases and decreases. The largest amount of water use (14,300 Mgal/d) occurred in 1980, which was almost 2.5 times more...
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...
Measurement of evapotranspiration in phreatophyte areas, Smith Creek Valley and Carson Desert, west-central Nevada, 1983
R. L. Carman
1993, Water-Resources Investigations Report 89-4118
Evaporation from bare soils and evapotranspiration from phreatophyte areas are major sources of natural groundwater loss in the Great Basin region of Nevada, Utah, and adjacent states. This study evaluated three methods for determining evapotrans- piration under natural conditions and provides quantitative estimates of evapotranspiration. Two of the methods used,...
Water resources data, Mississippi, water year 1992
M.L. Plunkett, F. Morris, W. T. Oakley
1993, Water Data Report MS-92-1
Water resources data for the 1992 water year for Mississippi consist of records of_stage, discharge, and water quality of streams; stage, and water quality of lakes and reservoirs and water levels and water quality of ground-water wells. This report contains records of water discharge at 82 gaging stations; stage records...
Comparison, analysis, and estimation of discharge data from two acoustic velocity meters on the Chicago Sanitary and Ship Canal at Romeoville, Illinois
Charles S. Melching, Kevin A. Oberg
1993, Water-Resources Investigations Report 93-4048
The acoustic velocity meter (AVM) on the Chicago Sanitary and Ship Canal (the Canal) at Romeoville, Ill., provides vital information for the accounting of the diversion of water from Lake Michigan. A detailed analysis of the discharge record on the Canal at Romeoville was done by the U.S. Geological...
