Abstract |
Urban areas contribute the highest nan-point source pollutant loading per unit area and not only customary pollutants but hazardous materials as well, thus urban areas have a great impact on water quality. In this paper, in order to estimate the urban non-point source pollutant loading in the Han River watershed, the Kuui and the Noryangjin basins were selected as representative spots and equipped with the water quality automatic monitoring system. These basins are located in the up and down stream of the urban area (Seoul). In this study, analysis on non-point source pollutant loading in regards to precipitation, runoff and water duality were investigated COD and SS parameters were selected to calculate unit loading data because these entities have a close relationship with non-point source pollution The results revealed that annual non-point source pollutant COD loading was 2,004 tons/yr, which is approximately 15% of the total COD loading of 13,874 tons/yr and annual non-point source pollutant SS loading was 29,631 tons/yr, which is 28% of the total SS loading of 75,285 tons/yr. |
