Surface-water-quality assessment of the lower Kansas River basin, Kansas and Nebraska: Results of investigations, 1987-90

Analysis of surface-water-quality data has enabled an assessment of water-quality conditions and trends and their relation to human and natural factors in the lower Kansas River basin, Kansas and Nebraska. This basin drains 15,300 square miles of predominantly agricultural land and is one of seven pilot studies completed as part of the National Water-Quality Assessment Program.
