Environmental chemist Walter Giger has passed away
November 19, 2025

Walter Giger was a pioneer in the life cycle analysis of environmental pollutants. He analysed, but also insisted that action be taken when the harmfulness of a substance was proven. His work on toxic nonylphenols attracted worldwide attention. Walter Giger passed away on 6 November 2025. With his passing, Eawag and environmental chemistry have lost an outstanding researcher, but for many he was also a good friend.

How can we get our groundwater clean?

For example, by measuring problematic substances directly at the body of water and in real time. This is possible thanks to the MS2field mobile mass spectrometer, which Eawag researcher Heinz Singer and his team present in the programme. (from min 12:35)

PEAK annual programme 2026

Get inspired by our diverse course program covering water and environmental topics such as resource-oriented sanitation systems, quagga mussels, conservation genetics, and satellite data for lake monitoring. Dive deeper into impact assessment in river restoration projects, lake modeling, and toxic cyanobacteria – in exchange with experts from research and practice.

Learn more about our main interests

Drinking water

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

Wastewater

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

Biodiversity

our research contributes to understanding and conserving aquatic biodiversity.

Ecosystems

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

Pollutants

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.

Water and development

our research supports the UN’s Sustainable Development Goals, first and foremost the objective of “clean drinking water and sanitation facilities”.

Societal decision-making

we are developing strategies and methods to support politics, administration, the economy and society in complex decisions.

Climate Change and Energy

we are exploring solutions to make the energy transition environmentally friendly and reduce the impact of climate change.
