Pesticides in near-surface aquifers: An assessment using highly sensitive analytical methods and tritium
In 1992, the U.S. Geological Survey (USGS) determined the distribution of pesticides in near-surface aquifers of the midwestern USA to be much more widespread than originally determined during a 1991 USGS study. The frequency of pesticide detection increased from 28.4% during the 1991 study to 59.0% during the 1992 study. This increase in pesticide detection was primarily the result of a more sens

Data on selected herbicides and two triazine metabolites in precipitation of the Midwestern and Northeastern United States, 1990-91
Weekly precipitation (rain and snow) samples were collected from 81 National Atmospheric Deposition Program/National Trends Network sites in the Midwestern and Northeastern United States for the analysis of herbicides. In addition, five high- elevation background sites along the Rocky Mountains and in Alaska were sampled to provide data on herbicides in precipitation at sites far from the study ar

Water-quality conditions of inflow, outflow, and impounded water at Rathbun Reservoir, Iowa, Clinton and Pomona Lakes, Kansas, and Harlan County Reservoir, Nebraska, May through August 1993
During May through August 1993, water-quality samples were collected twice from selected sites in Rathbun Reservoir, Iowa, Clinton and Pomona Lakes, Kansas, and Harlan County Reservoir, Nebraska. Samples were analyzed for selected physical and chemical properties, bacteria, major ions, nutrients, selected metals, total organic carbon, selected herbicides, and chlorophyll-a and -b. During May throu

Water resources on and near Indian lands in northeastern Kansas and southeastern Nebraska; hydrologic data through 1990
Four Kansas Indian Tribes, the Iowa, Kickapoo, Potawatomi, and Sac & Fox are interested in developing the water resources on and near their respective tribe lands. This report presents climatic and geohydrologic data that are useful in describing the available water resources in the 4,005-square-mile area in northeastern Kansas and southeastern Nebraska. Climatological data for 1961- 90 include mo

Effects of reservoirs on flood discharges in the Kansas and the Missouri River basins, 1993
The floods of 1993 were of historic magnitude as water in the Missouri and the Mississippi Rivers reached levels that exceeded many of the previous observed maximums. Although large parts of the flood plains of both rivers upstream from St. Louis, Missouri, were inundated, water levels would have been even higher had it not been for the large volume of runoff retained in flood-control reservoirs.

Herbicides and nitrate in near-surface aquifers in the midcontinental United States, 1991
The occurrence and distribution of selected herbicides, atrazine metabolites, and nitrate were determined for near-surface aquifers (within 50 feet of land surface) in the corn- and soybean-producing region of the midcontinental United States. The study region included all or parts of Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, and Wi

Assessment of nonpoint-source contamination of the High Plains Aquifer in south-central Kansas, 1987
Ground-water quality was assessed in a 5,000-square-mile area of the High Plains aquifer in south-central Kansas that is susceptible to nonpoint-source contamination from agricultural and petroleum-production activities. Of particular interest was the presence of agricultural chemicals and petroleum-derived hydrocarbons that might have been associated with brines that formerly were disposed into u

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 climate change; and

Geohydrologic systems in Kansas: Physical framework of the lower aquifer unit in the western interior plains aquifer system
The purpose of this Hydrologic Investigations Atlas is to provide a description of the principal geohydrologic systems in the Upper Cambrian through Lower Cretaceous rocks in Kansas.
