德克萨斯州圣安东尼奥市是美国最大的城市，其饮用水源完全依赖地下水。环境研究表明，从爱德华兹含水层的区域性撤离可能会减少含水层的泉水流量，并可能在极端干旱情况下危害几种濒危物种。因此，1995年，德克萨斯州成立了一个地下水管理局，规定必须减少目前从地下水中提取的水量。因此，圣安东尼奥市必须找到替代水源，以减少含水层的现有用水，并为未来的增长提供水源。 随着圣安东尼奥供水系统（SAWS）的工作人员开始规划新的供水，他们很早就认识到，当将具有不同化学成分的新水源引入其分配系统时，可能会对水质产生重大影响。为了解决这些担忧，SAWS启动了一项多水源整合研究，该研究全面分析了新水源可能对城市配水系统产生的影响。本文介绍的项目方法和方法可作为其他公用事业规划整合新水源的路线图。目前，该项目已得出初步结果，预计详细的测试方案、分析方法和最终结果将在未来的技术会议上公布。 包括参考、表格、数字。

The City of San Antonio, Texas, is the largest municipality in the United States that is solely dependent on groundwater as its drinking water source. Environmental studies have indicated that regional withdrawals from the Edwards Aquifer can reduce spring flows from the aquifer and potentially harm several endangered species during extreme drought situations. Consequently, in 1995, the State of Texas formed a groundwater regulatory authority that has mandated that current withdrawals from theaquifer must be reduced. Therefore, the City of San Antonio must find alternative water supplies to reduce their existing water use from the aquifer, as well as to provide for future growth. As the San Antonio Water System (SAWS) staff began planning for new supplies, they recognized early that the potential exists for major water quality impacts when new water sources with different chemistries are introduced into their distribution system. To address these fears, SAWS initiated a Multiple Source Integration Study, which is a comprehensive analysis of the impacts that the new water sources might have on the City's distribution system. The program methodology and approach is presented in this paper to serve as a road map for otherutilities planning to integrate new water sources. At this time, the project has developed preliminary results, and it is anticipated that the detailed testing protocol, analytical methods, and final results will be published at future technical conferences.
