Abstract Drinking water (DW) supply systems are vulnerable to deliberate and accidental water contamination events. Modern drinking water DW quality monitoring methods and accessibility to them have indicated that DW quality contamination events are still an issue all over the world. According to the data, in average 1906 accidents per year, related to DW contamination, occurred in China (Liu et al., 2015). Contamination events with high impact on society were detected in the USA, e.g., the spill containing crude 4-methykcyckihecabenethanol in 2014 contaminated the Elk River and influenced water supply to 300 000 consumers (Liu et al., 2016). Moreover, at least 400 000 people were affected from distribution of pathogens (Corso et al., 2003) during the outbreak reported in Milwaukee in 1993, which led to hundreds of hospitalizations and even deaths. Serious chemical contamination have been reported in Europe, for instance ammonia spillage in Tel Aviv (Israel) in 2001 (Winston et al., 2003) and contamination of aluminium sulphate in Camelford (UK) in 1988 (Clayton, 1989). A diversity of contamination events, their origin, and a need of reliable contamination detection systems were shown. On-line DW quality monitoring and early warning systems have been designed in order to warn the water utilities and consumers about the contamination events in DW supply system, and therefore to prevent possible contaminant exposure (Storey et al., 2011). The aim of this study was to evaluate the ability to detect various DW contamination events by on-line DW quality monitoring system.
