1998, Fact Sheet 116-98
Affordable, Integrated Access and Delivery of U.S. Government Satel lite and Geospatial Data to the American Public The U.S. Geological Survey (USGS) is a leader in collecting and archiving geospatial data and information about the Earth and in distributing this information to educational institutes; local, State, and Federal agencies; private industry;...
National Water-Quality Assessment Program: Island of Oahu, Hawaii
Stephen S. Anthony
1998, Fact Sheet 006-98
During the past 25 years, our Nation has sought to improve its water quality; however, many water-quality issues remain unresolved. To address the need for consistent and scientifically sound information for managing the Nation's water resources, the U.S. Geological Survey began a full-scale National Water-Quality Assessment (NAWQA) Program in 1991. This program is unique...
Herbicides in ground water of the Midwest: A regional study of shallow aquifers, 1991-94
Dana W. Kolpin, J. K. Stamer, D. A. Goolsby, E.M. Thurman
1998, Fact Sheet 076-98
The intensive herbicide use associated with the 'Corn Belt' marks the Midwestern United States as a region where herbicide contamination of ground water could be a problem. To better understand the regional occurrence of herbicides in shallow aquifers of the Midwest, a sampling network of 303 wells across 12 States...
Selenium in Reservoir Sediment from the Republican River Basin
Kyle E. Juracek, Andrew C. Ziegler
1998, Fact Sheet 080-98
Reservoir sediment quality is an important environmental concern because sediment may act as both a sink and a source of water-quality constituents to the overlying water column and biota. Once in the food chain, sediment-derived constituents may pose an even greater concern due to bioaccumulation. An analysis of reservoir bottom...
Use of Microgravity to Assess the Effects of El Nino on Ground-Water Storage in Southern Arizona
John T.C. Parker, Donald R. Pool
1998, Fact Sheet 060-98
The availability of ground water is of extreme importance in areas, such as southern Arizona, where it is the main supply for agricultural, industrial, or domestic purposes. Where ground-water use exceeds recharge, monitoring is critical for managing water supplies. Typically, monitoring has been done by measuring water levels in wells;...
Atrazine in Source Water Intended for Artificial Ground-Water Recharge, South-Central Kansas
Victoria G. Christensen, Andrew C. Ziegler
1998, Fact Sheet 074-98
Atrazine, an herbicide commonly applied to row crops, is of concern because of potential effects on water quality. This fact sheet describes atrazine in water from the Little Arkansas River in south-central Kansas. The river is being evaluated as a source of artificial recharge into the Equus Beds aquifer, which...
U.S. Geological Survey cooperative water-resources programs in Chester County, Pennsylvania
Charles R. Wood
1998, Fact Sheet 067-98
Since 1969, the U.S. Geological Survey (USGS) has had a cooperative water-resources investigation program with Chester County to measure and describe the water resources of the County. Generally, the USGS provides one-half of the program funding, and local cooperators are required to provide matching funds. Cooperation has been primarily with...
Changes to Idaho's statewide surface-water quality monitoring program since 1995
Ivalou O’Dell, Terry R. Maret, Susan E. Moore
1998, Fact Sheet 137-98
In 1990, the U.S. Geological Survey (USGS), in cooperation with the Idaho Division of Environmental Quality (formerly Idaho Department of Health and Welfare, Division of Environmental Quality), implemented a statewide water- quality monitoring program in response to Idaho’s antidegradation policy as required by the Clean Water Act (CWA). The objective...
U.S. Geological Survey Real-Time River Data Applications
Scott E. Morlock
1998, Fact Sheet 029-98
Real-time river data provided by the USGS originate from streamflow-gaging stations. The USGS operates and maintains a network of more than 7,000 such stations across the nation (Mason and Wieger, 1995). These gaging stations, used to produce records of stage and streamflow data, are operated in cooperation with local, state,...

D. J. Parliman, Joseph M. Spinazola
1998, Fact Sheet 054-98
In October 1992, the U.S. Geological Survey (USGS), in cooperation with the Idaho Division of Environmental Quality, Boise Regional Office (IDEQ-BRO), began a comprehensive study of ground-water quality in the lower Boise River Basin. The study in northern Ada County has been completed, and this report presents selected results of...
Upper Illinois River basin
Michael J. Friedel
1998, Fact Sheet 072-98
During the past 25 years, industry and government made large financial investments that resulted in better water quality across the Nation; however, many water-quality concerns remain. Following a 1986 pilot project, the U.S. Geological Survey began implementation of the National Water-Quality Assessment (NAWQA) Program in 1991. This program differs from...
