2003年和2004年，格伦代尔市完成了供水系统总体规划， 亚利桑那州和亚利桑那州梅萨。进行了延长期模拟（EPS）水龄和水源追踪分析，并将其用于 结合消毒副产物（DBP）形成的净化水水质曲线 评估各种替代改善措施对水质影响的可能性。这 本文介绍了配电系统详细评估的方法和结果 这两个系统的水质。 格伦代尔和梅萨都从两个水处理厂接收处理过的水，每个厂 具有不同DBP形成潜力的植物。此外，来自工厂的净化水 此外，还可从位于整个城市的水井中直接输入地下水 分配系统。除了水龄分析外，还进行了溯源分析 需要评估整个配水系统的净化水来源。 以一种可以解释和理解的方式有效地展示建模结果 易于理解，允许有效的质量控制审查和增加信心 在由此产生的建议中。本文详细介绍了 Glendale和Mesa的EPS水龄和溯源分析结果。包括表格，数字。

In 2003 and 2004, Water System Master Plans were completed for the cities of Glendale, Arizona and Mesa, Arizona. Extended period simulation (EPS) water age and source trace analyses were conducted and used in conjunction with treated water quality curves of disinfection byproduct (DBP) formation potential to evaluate the water quality impacts of various alternative improvements. This paper presents the methods and results of detailed evaluations of distribution system water quality as conducted for these two systems. Both Glendale and Mesa receive treated water from two water treatment plants, with each plant having different DBP formation potential. In addition, treated water from the plants is supplemented by direct input of groundwater from wells located throughout the distribution system. In addition to water age analyses, source tracing analyses were required to evaluate the source of treated water throughout the distribution system. Effective presentation of the modeling results, in a manner that can be interpreted and readily understood, allows for effective quality control review and increased confidence in the resulting recommendations. This paper presents details on the presentation of the results of the EPS water age and source tracing analyses for Glendale and Mesa. Includes table, figures.
