The incidence of coliphage in these potable water supplies reflect the probability of human pathogenic virus also surviving in these waters. The H 2 S paper-strip test was found to be an equally sensitive indicator of coliform presence compared to MF and MPN total coliform procedures.Mahidol UniversityEngineeringArticleSCOPUS
