Nitrate and pesticides in ground water in the eastern San Joaquin Valley, California : Occurrence and trends
Karen R. Burow, Sylvia V. Stork, N. M. Dubrovsky
1998, Water-Resources Investigations Report 98-4040-A
The occurrence of nitrate and pesticides in ground water in California's eastern San Joaquin Valley may be greatly influenced by the long history of intensive farming and irrigation and the generally permeable sediments. This study, which is part of the U.S. Geological Survey National Water-Quality Assessment Program, was done to...
Map and data for Quaternary faults and folds in New Mexico
M. N. Machette, S. F. Personius, K. I. Kelson, K. M. Haller, R. L. Dart
1998, Open-File Report 98-521
The "World Map of Major Active Faults" Task Group is compiling a series of digital maps for the United States and other countries in the Western Hemisphere that show the locations, ages, and activity rates of major earthquake-related features such as faults and fault-related folds; the companion database includes published...
Analysis of the streamflow-gaging station network in Ohio for effectiveness in providing regional streamflow information
D.E. Straub
1998, Water-Resources Investigations Report 98-4043
The streamflow-gaging station network in Ohio was evaluated for its effectiveness in providing regional streamflow information. The analysis involved application of the principles of generalized least squares regression between streamflow and climatic and basin characteristics. Regression equations were developed for three flow characteristics: (1) the instantaneous peak flow with a...
Lake Hickory, North Carolina: Analysis of ambient conditions and simulation of hydrodynamics, constituent transport, and water-quality characteristics, 1993-94
J. D. Bales, M. J. Giorgino
1998, Water-Resources Investigations Report 98-4149
From January 1993 through March 1994, circulation patterns and water- quality characteristics in Lake Hickory varied seasonally and were strongly influenced by inflows from Rhodhiss Dam. The upper, riverine portion of Lake Hickory was unstratified during much of the study period. Downstream from the headwaters to Oxford Dam, Lake Hickory...
Streamflow, water-quality, and biological conditions in the Big Black Creek basin, St. Clair County, Alabama, 1997
Celeste A. Journey, Amy E. Clark, Victor E. Stricklin
1998, Water-Resources Investigations Report 98-4127
In 1997 synoptic streamflow, water-quality, and biological investi- gations in the Big Black Creek Basin were conducted by the U.S. Geological Survey in cooperation with the City of Moody, St. Clair County, and the Birmingham Water Works Board. Data obtained during these synoptic investigations provide a one-time look at the...
Water-quality and algal conditions in the North Umpqua River Basin, Oregon, 1992-95, and implications for resource management
Chauncey W. Anderson, Kurt D. Carpenter
1998, Water-Resources Investigations Report 98-4125
This report describes the results of a synoptic water-quality and algal investigation during July 1995 at 36 stream sites in a 1,350 square-mile area of the North Umpqua River Basin, Oregon. The study area includes a headwaters hydroelectric project area, a Wild and Scenic reach in the main stem immediately...
Results of borehole geophysical logging and hydraulic tests conducted in Area D supply wells, former U.S. Naval Air Warfare Center, Warminster, Pennsylvania
Ronald A. Sloto, Kevin E. Grazul
1998, Water-Resources Investigations Report 98-4129
Borehole geophysical logging, aquifer tests, and aquifer-isolation (packer) tests were conducted in four supply wells at the former U.S. Naval Air Warfare Center (NAWC) in Warminster, PA, to identify the depth and yield of water-bearing zones, occurrence of borehole flow, and effect of pumping on nearby wells. The study was...
Effects of farming systems on ground-water quality at the management systems evaluation area near Princeton, Minnesota, 1991-95
M.K. Landon, G. N. Delin, J.A. Lamb, J. L. Anderson, R.H. Dowdy
1998, Water-Resources Investigations Report 98-4128
Ground-water quality in an unconfined sand and gravel aquifer was monitored during 1991-95 at the Minnesota Management Systems Evaluation Area (MSEA) near Princeton, Minnesota. The objectives of the study were to: (1) describe the effects of three farming systems on groundwater quality, and (2) evaluate the factors affecting ground-water quality and transport...
Estimating ground-water exchange with lakes using water-budget and chemical mass-balance approaches for ten lakes in ridge areas of Polk and Highlands counties, Florida
L. A. Sacks, Amy Swancar, T. M. Lee
1998, Water-Resources Investigations Report 98-4133
Water budget and chemical mass-balance approaches were used to estimate ground-water exchange with 10 lakes in ridge areas of Polk and Highlands Counties, Florida. At each lake, heads were monitored in the surficial aquifer system and deeper Upper Floridan aquifer, lake stage and rainfall were measured continuously, and lakes and...
Water-quality assessment of the Upper Mississippi River Basin, Minnesota and Wisconsin: Polychlorinated biphenyls in common carp and walleye fillets, 1975-95
Kathy Lee, Jesse P. Anderson
1998, Water-Resources Investigations Report 98-4126
Spatial and temporal distribution of polychlorinated biphenyls (PCBs) in common carp (Cyprinus carpio) and walleye (Stizostedion vitreum) fillets from rivers in the Upper Mississippi River Basin upstream of the outlet of Lake Pepin are summarized. PCB concentrations in common carp and walleye fillets collected from rivers in the UMIS...
Status of water levels and selected water-quality conditions in the Mississippi River Valley alluvial aquifer in eastern Arkansas, 1994-96
Gregory P. Stanton, Robert L. Joseph, Aaron L. Pugh
1998, Water-Resources Investigations Report 98-4131
During the spring of 1994 and 1996, water levels were measured in more than 600 wells completed in the Mississippi River Valley alluvial aquifer in eastern Arkansas. Water samples were collected during the summer of 1995 from about 375 wells completed in the alluvial aquifer and measured for specific conductance....
