Pesticides in drinking water in Switzerland

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!
Currently two relevant political initiatives for drinking water
«Drinking water initiative (TWI)» «Initiative for pesticide ban»
