CA18225 - Taste and Odor in early diagnosis of source and drinking Water Problems (WaterTOP) Triantafyllos Kaloudis Institute of Nanoscience & Nanotechnology, NCSR Demokritos, Greece

The Ninth IWA Symposium on Off-Flavours in the Aquatic Environment: RGU, 14-18 August 2011 Tri Andrea Dietrich Ricard Devesa Linda Lawton Chr. Edwards

Water T&O Workshop, 10-12 May 2017, Istanbul University Chris Avagianos Reyhan Akcaalan Tri Latife Koker Zuhal Tunc Meric Albay (Taking the photo)

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
