Pesticide and drug residues do not spare any river in the pthe swiss network. These toxic substances are presentes in concentrations that are too high in relation to the law, and this in all the measurement stations of the national monitoring network. This is shown by the data from the first long-term, uniform and national monitoring of micropolluants in surface waters (NAWA), which began in 2018.
