Stream Water Quality in the Conterminous United States -- Status and Trends of Selected Indicators During the 1980's

This is an electronic version of a paper published in the National Water Summary 1990-91 -- Stream Water Quality, U.S. Geological Survey Water-Supply Paper 2400.

This paper was not originally designed for electronic publication. Where possible figures have been recreated from the original files to provide the greatest clarity. Unfortunatly, files were not available for all figures, and they had to be scanned from the printed manuscript. All figures can be seen at full size by clicking on the "thumbnail" images in the text.

You will need a graphics viewer to see the full technical content of this report.
