Short summary
EPANET does not always conserve constituent mass during water-quality simulations. The failure to conserve mass can result in significant errors in constituent concentrations. We document the occurrence of mass imbalances, explain why they occur, provide recommendations for minimizing mass imbalances, and present a preliminary water-quality algorithm for use in EPANET that always conserves mass. Our paper should be of interest to anyone who performs water-quality simulations using EPANET.
