Variability of nutrients in streams in part of the Upper Mississippi River Basin, Minnesota and Wisconsin
Sharon E. Kroening, James R. Stark
1997, Fact Sheet 164-97
Physical conditions differ among the Mississippi River and its major tributaries in Minnesota and Wisconsin. Analysis of the environmental framework of the basin and analysis of historical water-quality information by the National Water-Quality Assessment (NAWQA) Program shows that nutrients (nitrogen and phosphorus) in streams in the Upper Mississippi River Basin...
Water-level changes in the High Plains aquifer, 1980 to 1995
Virginia L. McGuire, Jennifer B. Sharpe
1997, Fact Sheet 068-97
The High Plains aquifer underlies one of the major agricultural areas in the world, including parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. Ground-water irrigation expanded rapidly after 1940 in the area underlain by the High Plains aquifer (called the 'High Plains region' in this...
Agricultural chemicals in Iowa's ground water, 1982-95: What are the trends?
Dana W. Koplin, George Hallberg, D. A. Sneck-Fahrer, Robert Libra
1997, Fact Sheet 116-97
The Iowa Department of Natural Resources. Geological Survey Bureau: the University of Iowa Hygienic Laboratory; and the U.S. Geological Survey (USGS) have been working together to address this question. As part of the Iowa Ground-Water Monitoring Program (IGWM). water samples have been collected from selected Iowa municipal wells since 1982....
Unit-area loads of suspended sediment, suspended solids and total phosphorus from small watersheds in Wisconsin
Steven R. Corsi, David J. Graczyk, David W. Owens, Roger T. Bannerman
1997, Fact Sheet 195-97
Watershed planners in the Wisconsin Department of Natural Resources (WDNR) and in Wisconsin county governments use estimates of loads of total solids and total phosphorus in streams for numerous management purposes. A few examples of these are to establish load reduction goals, to estimate the relative magnitude of nonpoint sources...
Are walleye from Lake Roosevelt contaminated with mercury?
Martha L. Erwin, Mark D. Munn
1997, Fact Sheet 102-97
To find out, scientists from the U. S. Geological Survey (USGS) tested walleye and other sport fish from the upper Columbia River and Franklin D. Roosevelt Lake (Lake Roosevelt), the largest reservoir in Washington and a popular fishing spot.Findings:Walleye had higher concentrations of mercury than other sport fish.Larger walleye had...
Spatial variability of volatile organic compounds in streams on Long Island, New York, and in New Jersey
Anne K. O’Brien, Robert G. Reiser, Helle Gylling
1997, Fact Sheet 194-97
Volatile organic compounds (VOCs) are found in almost all natural and synthetic materials and are commonly used in fuels, fuel additives, solvents, perfumes, flavor additives, and deodorants. Potential health hazards and environmental degradation resulting from the widespread use of VOCs has prompted increasing concern among scientists, industry, and the general...
Changing Perceptions of World Oil and Gas Resources as Shown by Recent USGS Petroleum Assessments
Water Resources Division, U.S. Geological Survey
1997, Fact Sheet 145-97
The U.S. Geological Survey (USGS) periodically conducts geology-based assessments of the oil and gas resources of the world in recognition of the fact that the United States economic security is closely linked to energy resources outside the United States. Four such petroleum assessments have been published in recent years (Masters...
On the watch for geomagnetic storms
Arthur W. Green, William M. Brown III
1997, Fact Sheet 177-97
Geomagnetic storms, induced by solar activity, pose significant hazards to satellites, electrical power distribution systems, radio communications, navigation, and geophysical surveys. Strong storms can expose astronauts and crews of high-flying aircraft to dangerous levels of radiation. Economic losses from recent geomagnetic storms have run into hundreds of millions of dollars....
Herbicides in the Pecatonica and Yahara Rivers in Southwestern Wisconsin, May 1996-July 1996
David J. Graczyk, James P. Vanden Brook
1997, Fact Sheet 175-97
Herbicides, particularly those applied to corn, can be found in surface water and ground water in Wisconsin (Sullivan and Richards, 1996; Matzen and Saad, 1996). Wisconsin farmers applied 7.6 million pounds of corn herbicides during 1996. Because of public concern about the amount of herbicides applied to Wisconsin farm fields...
Radioactive Elements in Coal and Fly Ash: Abundance, Forms, and Environmental Significance
Robert A. Zielinski, Robert B. Finkelman
1997, Fact Sheet 163-97
Coal is largely composed of organic matter, but it is the inorganic matter in coal—minerals and trace elements— that have been cited as possible causes of health, environmental, and technological problems associated with the use of coal. Some trace elements in coal are naturally radioactive. These radioactive elements include uranium...
Radon in ground water in Guilford County, North Carolina
Timothy B. Spruill, Janie B. Williams, David R. Galeone, Douglas A. Harned
1997, Fact Sheet 147-97
Approximately 30 percent of the water used in Guilford County, North Carolina, is from ground-water sources. All rural supplies are from ground water; approximately 65,000 residents used ground water for their domestic water supplies in 1990.The U.S. Geological Survey (USGS), in cooperation with the Guilford County Soil and Water Conservation...
