Continuation of wastewater monitoring secured

February 19, 2026

The Swiss Federal Institute of Aquatic Science and Technology (Eawag) has been newly commissioned by the Federal Office of Public Health as the National Reference Centre for Wastewater Monitoring. This work centres around the collection of health data from municipal wastewater, and particularly that of viruses that are known to be pathogenic. A new national mandate has also been introduced for the analysis of substances related to pharmaceutical and illicit drug use.

Rare earths pollute Zurich's waters

February 10, 2026

An investigation in the canton of Zurich has shown that certain rare earth elements can enter bodies of water via wastewater treatment plants in concentrations that pose a risk to aquatic organisms. These elements are gadolinium, which comes from contrast agents used in healthcare facilities, as well as lanthanum and cerium, which are used in a number of wastewater treatment plants to remove phosphorus.

In Switzerland, most wastewater is treated in centralised treatment plants. Depending on the context, decentralised solutions can also offer advantages. These involve separating the various wastewater streams, treating them decentrally and recovering resources. The Eawag toolbox shows possible technologies for decentralised sanitation systems and helps to find the best solution for each objective.

we are investigating the basis for clean drinking water and sustainable management of drinking water resources.

we are investigating how to optimise wastewater infrastructures and overcome new challenges.

our research contributes to understanding and conserving aquatic biodiversity.

we are investigating biotic communities and their habitats in order to conserve ecosystem services for us humans.

we are investigating the effect of chemical substances on the environment and developing methods to remove them from drinking water, wastewater and bodies of water.
