To comply with the Stage 2 Disinfectants and Disinfection Byproducts Rule (DBPR), the Benicia Water Treatment Plant (WTP) has implemented best management practices and increased the frequency of trihalomethane (THM) monitoring. The Benicia WTP installed an online THM analyzer, THM-100™, from AMS to enhance THM management. The integration of the online THM analyzer has been crucial in managing THM levels, preventing regulatory breaches, and delivering safe drinking water to the City of Benicia.
