Why is GAC testing increased to hourly intervals?

Increased GAC (Granular Activated Carbon) testing to hourly intervals is primarily a response to incidents that can significantly impact water quality, such as main breaks or flooding. These events can introduce a wide array of contaminants into the water supply, including sediment and chemicals that may not be regularly present in the water system. By conducting more frequent testing during these incidents, operators can quickly identify any potential issues and take necessary actions to mitigate risks to water quality and safety. This proactive approach ensures that any changes in contaminant levels are addressed promptly, thus maintaining the integrity of the water supply and protecting public health.

Monitoring at such intervals during emergencies is crucial as it provides real-time data that allows for immediate adjustments in treatment processes or operational strategies, ultimately ensuring that the water remains safe for consumption.
