本文简要回顾了美国环境保护局和北宾州水务局进行的一项广泛的现场研究，该研究开发了一系列模型，用于调查配水系统中污染物的传播。本文解释了一个这样的模型在密苏里州卡布尔配电网污染物运动研究中的应用。文中还讨论了将这项工作扩展到一个大型水利设施——康涅狄格州中南部地区水务局。包括15个参考文献、表格和图表。

This article briefly reviews an extensive field study by the US Environmental Protection Agency and the North Penn Water Authority, which resulted in the development of a series of models to investigate contaminant propagation in a water distribution system. The application of one such model to the exploration of contaminant movement in the distribution network of Cabool, Missouri, is explained. An extension of this work to a large water utility--the South Central Connecticut Regional Water Authority--is also discussed. Includes 15 references, table, figures.
