WaterTOP - Main directions How can we manage the T&O problems in water?

▪ Sensory evaluation ▪ Chemical analysis, identification, diagnosis. ▪ Risk assessment, impacts. ▪ Prevention, control measures.

Can T&O serve as early warning for water quality problems?

▪ Geosmin, MIB and cyanotoxins? ▪ Off-odors and industrial pollution incidents? ▪ Citizen science? ▪ Sensors
