水質環境基準 達成 最適化 方案에 關한 硏究(Ⅰ) : Water Quality and Pollutant Loading from Dal cheon Basin 達水 流域 水質 및 流出負荷量 = A Development of the Most Appropirate Management Technics for the Achievement of Water Quality Standard(Ⅰ)

다국어 초록 (Multilingual Abstract)

This study was performed to investigate water pollution level and dischaging load of the up-stream area of Dal Cheon.
The results are as follows:
1. BOD concentration of Dal-Cheon river was shown to high level for May∼August in the rainy season, and low level for October∼March in the dry season. As the results, it was shown that rainfall influenced water quality of Dal-cheon river.
2. The annual average of Biochemical Oxygen Demands(BOD) were 2.2mg/ℓ at the influent area of the tributary of Dong Jin Chon, Which Was Polluted showing over 1.8mg/ℓ∼3.2mg/ℓ of BOD in average(the 2nd to 3rd/grade in environmental water quality standards)
3. The main cause of the deterioration or pollution of water quality has been from the polluted tributaries which flow into the Dal-cheon river. Since this pollution level of the tributariers has not decreased, adequate control measures must be necessary.
