With the latest analytical methods, potentially toxic substances can be detected even at very low concentrations. However, the aim of research is not merely to document such contamination but also to understand how it occurs in streams and groundwater, and to propose mitigation measures.

From flood protection and drinking water supply to the revitalisation of water bodies and hydropower production – water policy in Switzerland takes place in a wide variety of sectors. However, the exchange of information between politically divided players is often difficult. Science plays an important role as a bridge builder between the camps.

Microbes self-organise to grow into fascinating and complex patterns. The diversity of these patterns depends on a previously unknown factor, as researchers at Eawag have discovered. This might re-define how we view the concept of microbial biodiversity.

The Zambezi River Basin in southern Africa is a high-quality waterscape. But current rapid development threatens the waters of the Zambezi, particularly its tributaries. The challenge will be to ensure that mitigation measures keep up with population and economic growth to avoid degradation of water quality degradation.

The shift from fossil to renewable energy sources is essential for climate mitigation but will also significantly reduce the atmospheric input of the nutrients sulphur and selenium into soils. Sustainable solutions are therefore needed to supply intensively used agricultural soils with sufficient nutrients and to ensure a safe and healthy diet for the world's population.

An Eawag researcher has helped to develop a new approach to tracking how river water enters the groundwater. In the test area within the Emmental, the flow time within the aquifer has been shown to be much shorter than previously assumed. This has potential consequences during dry spells.

The last ice age, about 20,000 years ago, was significantly colder than previously thought. This is shown for the first time by systematically analysed samples of groundwater collected around the globe and the inert gases dissolved in it. Swiss groundwater from Uster (ZH) also contributed to the results.
