Pollutants

Ways to reduce pollution

Thousands of chemical substances end up in the aquatic environment, either by direct or indirect means. Some of these chemicals – hormones for example – have an effect on aquatic organisms, with far-reaching consequences. The water treatment plants cannot remove all of the pollutants from the wastewater. Eawag researches amongst other issues how supplementary measures in water treatment plants  affect biodiversity.

The earth’s water supply is changing because of global warming: the ratio of precipitation to evaporation is sinking, and additional arid zones may emerge. The speed at which this development is likely to take place has been analysed by an international team including Eawag researchers.  Read more

Selected research projects

EcoImpact is an Eawag-wide interdisciplinary research effort, strongly motivated by the planned modifications of the Swiss wastewater treatment plants.
Comprehensive monitoring of organic trace substances in surface waters is time-consuming and costly. The NAWA SPEZ project delivers data and analyses on the status of water pollution.
