River quality case study: the Willamette
Research report:The need for comprehensive river quality assessments, and problems confronting river basin managers are discussed. A river quality assessment performed by the USGS on the Willamette River Basin, Ore., in January 1973, is described. Geology and topography of the study area are reviewed. Trace metal concentrations and algal growth rates were surveyed. Results indicated high nitrogen and phosphorus concentrations in the Willamette River, but excessive growth rates for algae were not observed. Synoptic data collection programs to augment routine monitoring programs are needed for further studies in this field. Mathematical models must be formulated from realistic data and reliable assumptions. Results also implied that secondary treatment of point source discharges drastically change self-purification characteristics of rivers. (1 graph, 2 maps, 7 photos)
