Abstract
Although the Safe Drinking Act and its amendments (SDWAA) has been interpreted as meaning that MCLs shall be met at the consumer's tap, most regulatory concern has been focused on water as it leaves the treatment plant before entering the distribution system. The only SDWAA regulation that emphasize system sampling are the trihalomethane and monitoring regulations. The paper provides the results of a study conducted in cooperation with the North Penn Water Authority in Lansdale, PA that resulted in development of a series of models for predicting the spatial distribution of contaminants in the distribution system. The study concluded that hydraulic modeling coupled with extensive field verification is required to develop usable predictive models.
