For a two-year period, the states of Colorado, Vermont and Washington tested the effectiveness of ten surveillance methods for identifying waterborne disease. Nine were active surveillance methods, soliciting illness reports; one was passive, relying on voluntary disease reporting. One waterborne disease outbreak was identified through use of the nine active methods, while 14 were reported through the passive surveillance method. The presence of coliform bacteria during routine water testing was not related to illness in the community.
在两年时间里，科罗拉多州、佛蒙特州和华盛顿州对十种识别水源性疾病的监测方法的有效性进行了测试。其中九种是主动监测方法，即征集疾病报告；一种是被动监测方法，依靠自愿疾病报告。通过使用九种主动方法识别出一起水源性疾病暴发，而通过被动监测方法报告了14起。常规水质检测中大肠菌群的存在与社区疾病无关。
