| Abstract |
Monitoring strategies for characterizing the bacteriological quality of water in the distribution system require a complete understanding of a variety of interrelated aspects that include treated water quality, water supply retention in storage and infrastructure deterioration in the distribution system. A study of field data from several water supply utilities was used to highlight some innovative interpretations of compliance monitoring data. Major perceptions include: The use of a 5 percent coliform frequency of occurrence limit highlights compliance significance in those situations where there are clusters of positive samples containing less than 4 coliforms per 100 mL. Unfortunately, this presence/absence concept does not provide any indication of the magnitude of a contamination event. |
