Dale M. Robertson
1996, Fact Sheet 208-96
In 1991, the U.S. Geological Survey (USGS) began full implementation of the National Water-Quality Assessment (NAWQA) Program. The goals of the NAWQA program are to (1) provide a nationally consistent descrip- tion of water-quality conditions for a large part of the Nation's water resources, (2) define long-term trends (or lack...
Salinity in the Colorado River in the Grand Valley, western Colorado, 1994-95
David L. Butler, Paul B. von Guerard
1996, Fact Sheet 215-96
Salinity, or the dissolved-solids concentration, is the measure of salts such as sodium chloride, calcium bicarbonate, and calcium sulfate that are dissolved in water. About one-half of the salinity in the Colorado River Basin is from natural sources (U.S. Department of the Interior, 1995), such as thermal springs in the...

Description of the ground-water flow system in the Portland Basin, Oregon and Washington
William D. McFarland, David S. Morgan
1996, Water Supply Paper 2470-A
An increasing dependence on ground-water resources in the Portland Basin has made it necessary for State and local governments to evaluate the capability of the ground-water system to meet present and future demands for water. This report describes the regional ground-water system and provides a conceptualization of the aquifer system....

Verification of a one-dimensional, unsteady-flow model for the Fox River in Illinois
Audrey L. Ishii, Mary J. Turner
1996, Water Supply Paper 2477
The previously-calibrated application of the Full EQuations (FEQ) model of one-dimensional, unsteady flow to a 30.7-mile reach of the Fox River in northeastern Illinois was verified with discharge, stage, and dye-transport data collected during a 12-day period in October-November 1990. The period included unsteady flow induced by the operation of...

Simulation of wastewater effects on dissolved oxygen during low streamflow in the Red River of the North at Fargo, North Dakota, and Moorhead, Minnesota
Edwin A. Wesolowski
1996, Fact Sheet 235-96
Pursuant to Section 303(d) of the Clean Water Act, both North Dakota and Minnesota identified part of the Red River of the North (Red River) as water-quality limited. The states are required to determine the total maximum daily load (TMDL) that can be discharged to a water-quality limited reach from...

1996, Water-Resources Investigations Report 96-4199
Bacterial injury, survival, and regrowth were investigated by use of replicate flow-through incubation chambers placed in the Cuyahoga River or Lake Erie in the greater Cleveland metropolitan area during seven 4-day field studies. The chambers contained wastewater or combined-sewer-overflow (CSO) effluents treated three ways-unchlorinated, chlorinated, and dechlorinated. At timestep intervals,...
