The use of the BNETQ Water Quality Model reliably predicted THM levels within Charlotte Mecklenburg Utility Department (CMUD's) distribution system. Although the development of water quality models is still in its infancy, the tools are available to develop a model to predict THM levels for a given system with knowledge of its operating conditions. The important factors to consider when developing the model are as follows: The accuracy of the water quality model is dependent on the accuracy of the water hydraulic model. The factor common to the prediction of all types of constituents, be they reactive or conservative, is that they depend on time. Without a solid hydraulic model, the water quality model will not be able to reliably predict water quality parameters; A knowledge of the water quality of the system is imperative to predicting THM formation potential. The modeler must understand what constituents affect the formation potential. He must also understand which of those constituents vary within his system and how; Sampling within the distribution system aids in the model calibration. It is important for grab samples to be taken on the same day to maximize the effectiveness of the hydraulic model.
