Regional pattern of pesticides in groundwater e.g. Chloridazon (BAFU → NAQUA) Chloridazon: regional concentration pattern for main substance and metabolites Sugar beet /fodder beet: Schweizerischer Verein des Gas- und Wasserfaches (SVGW) 16

Pesticides in drinking water in Switzerland 70% of groundwater sampling sites with main land use farmland show concentration of pesticides or metabolites > 0.1 µg/L Atrazine detected in many water samples > 0.1 µg/L (was banned 2007 in CH) New substances detected, e.g. Chlorothalonil Unknown impact of cocktail of pesticides in ground- and drinking water Consumer and water utilities don’t want pesticides to be in drinking water! 17

Currently two relevant political initiatives for drinking water 2018 March 2019 20.6.2019 prob. May 2020 end 2020 «Drinking water initiative (TWI)» Parliament: Public Vote on TWI Agriculture counter project Consultation on and Pesticide policy AP22+ «Initiative for pesticide ban» for initiatives: Agriculture policy ban initiative defined yes or no?
