The objective of this study is to evaluate and analyze Sincheon basin water environment system. The data were collected from 2010 August to 2016 December including BOD, SS, T-N, T-P. The results were as followed. As the result of comparing the amount of BOD generated by pollution sources in the Sincheon water system, industrial was the highest at 33,259.4 kg/day. In comparison with the tributary, it was estimated that Dong-Du water system reveals the highest level of BOD in the industry. Population and livestock was high in CheongDam and Sang-Pae water system. With the inflow stream of Hyo-Chon, Suk-Woo and Sang-Pae, the pollution degree of BOD and T-N level of Sincheon increased and pollution degree of tributary was higher than that of Sincheon's main stream. The main reason of pollutant of Suk-Woo was from untreated wastewater, and it influenced downstream of Suk-Woo. Hyo-Chon stream satisfy the water quality standard, but Zn was designated as a Monitoring contaminants, was high as 14.670 mg/L (standard 0.02~2.45mg/L)because of textile wastewater. And Sang-Pae stream was polluted by livestock wastewater of livestock farms as a nonpoint source.
