To compare with total coliforms(TC) and injured coliforms(IC), 185 water samples in Seoul were tested with desoxycholate agar and mT7 agar from September to December in 1998. Percentage of IC compared with TC was 94%, 173%, 17%, 16% and 418% in drinking water, municipal water, river water, leachate, waste water respectively. Specially, the most percentage of IC, compared with TC in waste water, was caused by drugs input s stress. Besides, total fecal coliforms(TFC) compared with TC in river and waste water was 3.70%, 0.7% respectively, and injured fecal coliforms(IFC) compared with IC, was 4.80%, 0.1 % respectively. Percentage of TFC compared with TC was much higher in river than waste water, and percentage of IFC compared with IC was bigger in waste than river water, Conclusively, the number of injured coliforms should be moniterized in municipal water and waste water.
