Water Quality Surveillance and Response

Event Detection System Deployment, Integration, and Evaluation System (EDDIES)

The Event Detection System Deployment, Integration, and Evaluation System (EDDIES) is a downloadable tool developed by EPA to facilitate implementation of online water quality monitoring. It was initiated for, and has been enhanced based on, the needs of the EPA’s Water Security Initiative pilot utilities as they select and implement event detection. Anticipated users of EDDIES include water utilities, contractors, Event Detection System (EDS) developers and researchers. EDDIES generates datasets for EDS analysis, using utility data and simulating contamination events. It then analyzes the output produced by the EDS to evaluate EDS performance.
