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.

Bypass tunnels designed to reduce sediment deposition in reservoirs also have beneficial effects on ecological conditions in downstream receiving waters. This was the conclusion of a study carried out on the Solis reservoir in Graubünden by biologists from Eawag and the Zurich University of Applied Sciences (ZHAW).  Read more
