Multi-Site Event Detection System for Water Distribution Systems Contamination
Current Event Detection Systems (EDS) used to identify potential contamination in public water distribution systems are not reliable. The variability of water quality parameters can exhibit practically unlimited combinations of rapid changes due to entirely normal causes. In a single-site EDS these normal conditions are often misinterpreted as contamination events, leading to many false alarms. The root cause of this problem is that these EDS all use a "single-site" approach, meaning that they monitor each site independently of all others, rather than evaluating all sites as an integrated network. This research project will develop a “multi-site approach” that is capable of analyzing simultaneous data from multiple locations to infer the contamination event probability.
