| Abstract |
The monitoring strategies for characterizing the microbiological quality of water in the distribution system require a thorough understanding of a variety of interrelated aspects: the treated water quality, the water supply retention in storage, and infrastructure deterioration. Evaluation of the routine monitoring strategies practiced by 1796 utilities suggests some water systems need to revise their programs to focus more on sampling at the peripheries of the pipe network and on monitoring water quality more uniformly over a 30 day period. Monitoring strategies must be flexible, being individually designed on a case by case basis. The plan must also be usable for all three levels of monitoring activity: (a) routine monitoring to meet the regulatory requirements; (b) specialized monitoring during seasonal biofilm occurrences; and (c) priority monitoring during periods of boil water conditions. |
