ASSESSMENT OF DRINKING WATER QUALITY USING INDICATOR BACTERIA AND BACTERIOPHAGES

AUDICANA A. / CANCER M. / MENDEZ J. / et al. - ARTICLE DE PERIODIQUE - 2004

The number of samples from metropolitan water supplies containing more than 0.1mg/l of chlorine that contained phages clearly outnumbered those containing indicator bacteria. Some association was observed between rainfall and the presence of indicators. Bacterial indicators and phages were detected in a higher percentage than in samples of tap water. Indicator bacteria were detected more frequently than bacteriophages in sediments of service reservoirs and water dead end samples.
