Assistance Type: WATER QUALITY ALERT RESPONSE
Reasons: Disinfection Byproducts
 
Details: Discussed the possible causes of the high DBP levels in the Q4 2024 DBP samples. The plant did have some issues with membrane fouling and were using the slow sand filters as much as possible during the high water flows. There weren't any changes in operations for reservoir levels or flushing. High DBPs seem to be a result of a combination of small changes.

System will increase flushing next time they hear of issues with filters during high river water events.
