Abstract
The Safe Drinking Water Act and its Amendments are posing a major challenge to drinking water utilities in the United States. At times, quality and quantity demands may conflict, and a utility may be required to use sources of marginal quality which makes achieving these goals even more difficult. That has been the situation in which the North Marin Water District in California, has found itself and which has led to the utilities' desire to develop and calibrate a water quality model. The model simulated the propagation of Total Trihalomethanes (TTHM) and chlorine residuals in the North Marin Water District (NMWD) distribution system. It was used to evaluate strategies for minimizing TTHM formation while maintaining adequate chlorine residuals in the system.
