Contaminant propagation models can be coupled with hydraulic models and used to model chemical, biological, and hydraulic changes that take place in the distribution system and to predict the spatial and temporal distribution of contaminants throughout the system. This paper presents an overview of contaminant propagation modeling research and development, and attempts to provide examples in which these types of models have been applied to managing water quality in distribution systems. Water quality modeling can address water quality problems related to blending; chlorine residual; or the effects of disturbances, such as a line break, meter repairs or flushing program. A number of studies, including those involving calibration of models, effect of storage on water quality, measuring chlorine residual, and locating water quality monitoring stations, are discussed. Areas of future research are discussed.
