Drinking Water

Prevention is better than cure

Thanks to the fact that Switzerland’s surface waters have been kept clean, this maxim has to a large extent been upheld. However, the presence of new (harmful) substances allows no room for complacency on this front. Globally, there is an urgent need for cost-effective and energy-efficient water treatment solutions on various scales - all the way through to wastewater recycling.

Many experts describe the health effects of drinking water contaminated with toxic concentrations of arsenic as the greatest mass poisoning in human history. A risk model developed by Eawag researcher Joel Podgorski now shows that up to 220 million people worldwide could be affected.

In order to increase the permeability of the rock for applications such as the use of geothermal energy, rock is artificially broken. Until now, there was a lack of methods to track this process in the field in real time. Thanks to a new technique, this gap can now be closed, as a study by Eawag and ETH Zurich shows.

Selected research projects and programs

Inhalation of legionella bacteria – which thrive in warm water – can cause illness: in a new project, an Eawag-led multidisciplinary research team is investigating how the risks associated with these bacteria can best be managed.
An inter- and transdisciplinary strategic research program that strives to develop novel non-gridconnected water and sani- tation systems that can function as comparable alternatives to network-based systems.
This project facilitates the exchange of data, maps and information on geogenic contaminants (focussing on arsenic and fluoride) via the web-based Groundwater Assessment Platform (GAP)
