EVALUATING WATER QUALITY IMPACTS OF SMALL STREAMS ON MAJOR URBAN RIVERS

An in-depth study of the effect of low water quality in the small streams on the quality of water in major rivers in Allegheny County, Pennsylvania, has demonstrated that the small stream impact is minimal. The study considered both inorganic and organic pollutant problems. Total flow frequencies from the tributaries were estimated by analyzing river data, and a procedure was determined for partitioning this flow among the small streams and drainage areas. The methodology is illustrated with a case study which concludes that for Allegheny County, little improvement in major river quality can be expected from upgrading the water quality of small streams.
