AWWA ACE93107

Whenever an enteric disease outbreak occurs, or even when a small outbreak happens and drinking water is implicated, an investigation should take place to help determine if drinking water was a contributing factor. This investigation will attempt to overlay the epidemiological data collected by local, state, and federal health agencies, and any and all data available from the drinking water systems. These data will not be limited to water quality data, but will also include information about system operation, abnormal conditions (power losses or pipe breaks), and almost any other available information about the water system. Each of the three case studies presented in this paper will focus on a different method of contamination of the drinking water that resulted in diarrheal illnesses and in some instances deaths. The first case described is a contamination in a single facility, the second case describes contamination of a distribution system, and the third case discusses contamination that passed through a water treatment plant. This information should help those involved with future outbreaks with guidance to determine what types of information are useful in waterborne disease investigations.
