保护美国的供水系统免受恐怖袭击已成为联邦和地方的优先事项。常规采样和分析已被提议作为一种潜在的监测方法，可用于及早检测饮用水系统中的污染事件。利用威胁集成脆弱性评估计算框架，对三种常规抽样方案的效益进行了评估，并与实时监测方案进行了比较。结果通过折衷曲线来说明，这些曲线展示了在给定故意的生物或化学攻击的情况下传感器网络所提供的好处。此外，结果表明，响应时间是关键的，基于物理采样的监测(采样频率为24小时或更长)的有效性远低于实时监测。
Protecting the water systems of the United States from terrorist attacks has become a federal and local priority. Routine sampling and analysis has been proposed as a potential monitoring approach that could be used to provide early detection of contamination events in drinking water systems. Using the threat ensemble vulnerability assessment computational framework, an evaluation of the benefits of three routine sampling programs is compared to a real-time monitoring program. The results are illustrated by tradeoff curves that demonstrate the benefits provided by a sensor network given an intentional biological or chemical attack. Further, the results show that response time is critical and physical sampling-based monitoring with sample collection frequencies of 24 h or longer are much less effective than real-time monitoring.
