Monitoring strategy must be sensitive to frequent and unpredictable fluctuations in water quality caused by major storm events and seasonal destratifications of the lake/impoundment. Therefore, daily monitoring of raw source water and the finished-water quality entering distribution systems at a point near the first customer is necessary. When water-quality fluctuations reach beyond the 90th percentile for coliforms, morning and afternoon, afternoon sampling of the finished water should be done to demonstrate continued treatment barrier protection. Monitoring data should not only be utilized to form a continual historical record that demonstrates water-quality suitability for minimal treatment but also as an integral part of guidance in making day-to-day changes in process control to avoid any chance for microbial penetration into the public water supply.
