Greater Cincinnati Water Works Case Study

The following reports document the implementation of a surveillance and response system (SRS) at Greater Cincinnati Water Works and describe the evaluation of data that was collected from the SRS and its components. The first report describes the status of the SRS and its components following implementation. The remaining reports describe the evaluation of data that was collected from the SRS and its components during an extended period of operation.
