本文是一系列论文的一部分，详细介绍了该技术的发展和应用 水安全倡议（WSI）项目的实施 美国环境保护局（USEPA）和大辛辛那提水厂（GCWW）。本文探讨 GCWW对实验室发展和水质的展望 监督支持该倡议的职能。 WSI的开发需要在三个具体方面提供水质监测支持 地区。第一个领域是传统的实验室取样和分析功能。 这 包括简单的湿化学分析以及更复杂的有机、生物、， 以及放射分析。第二个领域是在线监测。这方面包括 安装、维护和运行位于 整个分配系统。第三个领域是实地测试。这方面包括 在现场进行常规分析，以收集水质信息以及 测试以支持现场特征描述，并确保响应者的安全 疑似污染事件。 WSI所需的许多分析本质上是例行的，并且定期进行 在WSI之前由GCWW执行。然而，其他人需要大量设备， 在实施过程中需要开发的时间、设施和技能 WSI。

This paper is presented as part of a series of papers detailing the development and implementation of the Water Security Initiative (WSI) project as a partnership between the US Environmental Protection Agency (USEPA) and the Greater Cincinnati Water Works (GCWW). This paper examines GCWW's perspective of the development of the laboratory and water quality monitoring functions to support the Initiative. The development of the WSI requires water quality monitoring support in three specific areas. The first area is the traditional laboratory sampling and analysis functions. This includes simple wet chemistry analyses as well as the more complex organic, biological, and radiological analyses. The second area is on-line monitoring. This area includes installation, maintenance, and operation of on-line water quality monitors located throughout the distribution system. The third area is field testing. This area includes routine analysis performed in the field to gather water quality information as well as testing to support site characterization and to assure the safety of responders to a suspected contamination event. Many of the analyses required for the WSI are routine in nature and were regularly performed by GCWW before the WSI. However, others required significant equipment, time, facilities and skill that needed to be developed during the implementation of the WSI.
