The City of Benicia, California, implemented a series of best management practices to help minimize the formation of trihalomethanes (THMs) in their distribution system and ensure regulatory compliance. In addition to minor pre-treatment and disinfection process changes, the Benicia Water Treatment Plant (WTP) decided to monitor THM levels more frequently using the online THM analyzer, THM-100™, to provide accurate and timely information regarding THM levels in their treated water. Integrating the online THM-100 analyzer at Benicia WTP has become an essential element to help support the delivery of treated water of the highest quality.
