本文回顾了美国环境保护局（U.S.Environmental Protection Agency）和北宾夕法尼亚水务局（North Penn Water Authority）进行的广泛实地研究的结果，该研究开发了一系列可用于研究配电系统中污染物传播的模型。本文给出了一个例子，其中美国环保局开发的模型被用于探索密苏里州卡布尔市配水系统中发现的水性污染物的移动。最后，将讨论将这项工作扩展到一个大型饮用水公用事业公司的情况，并讨论在这方面取得的进展- 提交日期。

This paper reviews the results of an extensive field study conducted by the U.S. Environmental Protection Agency and the North Penn Water Authority, which resulted in the development of a series of models that can be used to study contaminant propagation in distribution systems. An example is presented in which the model developed by the U.S. EPA was applied to explore the movement of a waterborne contaminant found in the Cabool, Missouri, distribution system. Finally, an extension of this work to a large drinking water utility, will be discussed and the progress to-date presented.
