Water quality in Switzerland: WWF platform highlights pesticide contamination between 2019 and 2024

The WWF Switzerland has launched an online platform highlighting pesticide contamination in Swiss water sources between 2019 and 2024. The platform includes four interactive maps showing rivers, streams, and groundwater affected by pesticides, detailing which substances are involved, their risk levels, and changes in concentration over time. The initiative aims to make this information more accessible to the public. The data was obtained from the Federal Office for the Environment and compiled into an easy-to-use tool. The platform also addresses ongoing concerns, such as the detection of triazole in Lake Geneva in 2025.

A new online platform launched by Switzerland's World Wildlife Fund (WWF) highlights pesticide contamination in rivers, streams, and groundwater between 2019 and 2024. The tool includes four interactive maps showing affected areas, types of chemicals involved, risk levels, and changes in concentrations over time. Eva Goldmann, an agricultural expert at the foundation, stated that after requesting data from the Federal Office for the Environment, they compiled all information into an easy-to-use format. This initiative marks a first for the organization. The maps, two for surface waters and two for groundwater, provide an overview of pesticide load and allow searches for around sixty individual substances. For example, glyphosate and 1,2,4-triazole, which gained attention following pollution detected in Lake Geneva during summer 2025, are included. Goldmann emphasized that pesticides pose an invisible threat and remain a significant issue, sometimes detectable years after their ban, such as with chlorothalonil. Detailed data reveal that certain Swiss municipalities have heavily contaminated groundwater with pesticides and their breakdown products. According to federal authorities, these substances significantly pollute groundwater. The data show for the first time where the problem is most severe.
