Dong Cheon is one of the severely polluted streams by domestic sewage and industrial wastewater. In order to evaluate the effect of domestic sewage and sediment characteristics on water quality, a study was carried out at downstream of Dong Cheon in Busan. The range and mean values of water quality in Dong Cheon were as follows: DO 0.8-11.0mg/l: SS 3-113mg/1: COD 12.4-40.8mg/1: BOD 12.6-48.1mg/1: NH4-N 0-l.10mg/l. Bottom sediment of Dong cheon mainly consisted of fine sand and silt, and contents of organic meter were very high considering the results of sediment BOD. According to the results of this study, stagnation of high pollutant load of water and rapid oxygen uptake of sediment lead the stream water to anoxic condition and it caused offensive oder in the downstream of Done Cheon during summer.
