Automated biomonitoring systems provide continuous, real-time monitoring of changes in water quality and can rapidly identify toxicity associated with a wide range of chemical contaminants while increasing public confidence in drinking water quality. Biomonitor use is widespread in Europe but rare in the United States. This paper illustrates how biomonitors can contribute to an early warning monitoring system for source and finished water protection using case studies of a biomonitor that continuously monitors the fish ventilatory patterns integrated with basic water quality parameters. At two water utilities, the biomonitor was operational . 96% of the time. Toxicity alarms occurred for a small diesel oil spill and a probable agricultural chemical release. The case studies provide a context for a discussion of considerations important for biomonitor implementation, including: toxicant responsiveness, event confirmation, implementing biomonitors in a decision-making process, and costs. Recommendations are provided for biomonitor use at raw water intake and in distribution systems. |
