Occurrence and transport of agricultural chemicals in the Mississippi River basin, July through August 1993 Occurrence and transport of agricultural chemicals in the Mississippi River basin, July through August 1993
Heavy rainfall and severe flooding in the upper Mississippi River Basin from mid-June through early August 1993 flushed extraordinarily large amounts of agricultural chemicals (herbicides and nitrate) into the Mississippi River, many of its tributaries, and, ultimately, the Gulf of Mexico. Even though extremely high streamflows were recorded during the flood in 1993, concentrations of...

Description of water-resource-related data compiled for Harvey County, south-central Kansas Description of water-resource-related data compiled for Harvey County, south-central Kansas
Site, construction, geologic, water-level, water- quality, water-withdrawal, and well-survey data for sites in Harvey County were compiled in cooper- ation with the Harvey County Health Department as part of the Kansas Department of Health and Environment's Local Environmental Protection Program (LEPP). These data were entered into a relational data-base management system (RDBMS) to...

Reconnaissance data for selected herbicides, two atrazine metabolities, and nitrate in surface water of the Midwestern United States, 1989-90 Reconnaissance data for selected herbicides, two atrazine metabolities, and nitrate in surface water of the Midwestern United States, 1989-90
Water-quality data were collected from 147 rivers and streams during 1989-90 to assess selected preemergent herbicides, two atrazine metabolites, and nitrate in 10 Midwestern States. This report includes a description of the sampling design, data collection techniques, laboratory and analytical methods, and a compilation of constituent concentrations and quality-assurance data. All water...

Flood discharges in the upper Mississippi River basin, 1993 Flood discharges in the upper Mississippi River basin, 1993
From mid-June through early August 1993, flooding was severe in the upper Mississippi River Basin following a wet-weather pattern that persisted over the area for at least 6 months before the flood. The magnitude and timing of several intense rainstorms in late June and July, combined with wet antecedent climatic conditions, were the principal causes of the flooding. Flood-peak...

Sensitivity of water resources in the Delaware River basin to climate variability and change Sensitivity of water resources in the Delaware River basin to climate variability and change
Because of the "greenhouse effect," projected increases in atmospheric carbon dioxide levels might cause global warming, which in turn could result in changes in precipitation patterns and evapotranspiration and in increases in sea level. This report describes the greenhouse effect; discusses the problems and uncertainties associated with the detection, prediction, and effects of...

Geohydrologic systems in Kansas — Geohydrology of the lower aquifer unit in the western interior plains aquifer system Geohydrologic systems in Kansas — Geohydrology of the lower aquifer unit in the western interior plains aquifer system
The purpose of the investigation is to provide a description of the principal geohydrologic systems in Upper Cambrian through Lower Cretaceous rocks in Kansas. This investigation was made as part of the Central Midwest Regional Aquifer-System Analysis (CMRASA). The CMRASA is one of several major investigations by the U.S. Geological Survey of regional aquifer systems in the United States...

Precipitation in the upper Mississippi River basin, January 1 through July 31, 1993 Precipitation in the upper Mississippi River basin, January 1 through July 31, 1993
Excessive precipitation produced severe flooding in a nine-State area in the upper Mississippi River Basin during spring and summer 1993. Following a spring that was wetter than average, weather patterns that persisted from early June through July caused the upper Midwest to be deluged with an unusually large amount of rainfall. Monthly precipitation data were examined at 10 weather...

National water summary 1990-91: Hydrologic events and stream water quality National water summary 1990-91: Hydrologic events and stream water quality
National Water Summary 1990-91 Hydrologic Events and Stream Water Quality was planned to complement existing Federal-State water-quality reporting to the U.S. Congress that is required by the Clean Water Act of 1972. This act, formally known as the Federal Water Pollution Control Act Amendments of 1972 (Public Law 92-500), and its amendments in 1977,1979,1980,1981,1983, and 1987, is the...
