다국어 초록 (Multilingual Abstract)

Water of river gets great concern about its quality, which might be polluted with pollutant from various industrial plants booming along the river sides in recent years. As a first step to prevent any applicable damage due to water pollution, survey on the water quality of Keum river at Sintanjin, Maepo, Taepyongri, Kongu, Puyeo and Kanggeng, six regions was conducted during september, 1977 through august, 1978 and the results were summarized as follows:
1. There were no significant regional and monthly difference in pH, NO_2-N, and NO_3-N of water.
2. The BOD at Puyeo, Kanggeng was 3.9 to 5.6, 5.6 to 6.0 ppm, respectively, and those values reached the limiting level for tap water sources.
3. The BOD at Maepo, where Daejeon streams meet, was found 1.9, 3.0, and 2.1 times higher than those at Sintanjin region, during september, october and november, respectvely.
4. Content of DO was 7.6±3.8 ppm in all surveyed regions and varied with water temperature and regional difference.
5. There were found regional difference and monthly difference in water hardness, suspended solid and NH_3-N.
