Drinking water is the number two on the list of the "necessities for human life" where the number one is breathing air and number three is food. Humans can survive for minutes only without breathing air. They are able to survive for some days without drinking water. Food is less critical, since humans are able to adapt to a large variety of food stuff, while there are no substitutes for breathing air and drinking water.

This short remark on the necessity of water triggers a number of questions where the composition of drinking water is of particular importance. The basic chemical ingredient of water is H2O which, in its pure appearance, is not good for human life. Good drinking water contains a number of trace elements which contribute to the functionality of the human body. The effects of such trace elements can be measured and classified regarding human health and well-being.

But would we tolerate bad taste, bad smell or strong colour in an enjoyable drinking water even if the causative ingredient is harmless to human health? The European Well and Fountain Society carried-out a survey on "good drinking water" where non measurable and even emotional criteria of "good" water were explicitly included. The invited participants of the survey are more than 40 well renowned water experts.

The results of this survey will be presented for further discussion in the afternoon of Nov. 25, 2015 at the Fraunhofer Institute IOSB in Karlsruhe by means of a poster exhibition. 



The Participants of the IWRM Karlsruhe 2015 event are invited to visiting the Rheinwald water utility of the City of Karlsruhe in the morning of Thursday, Nov. 26, 2015 and learn about the production of very high quality drinking water in the highly industrialized Upper Rhine Valley. This region is well known in Europe for its very efficient environment protection activities and systems. 


We would appreciate you to joining us at the IWRM 2015. Discuss the solution of highly relevant and urgent water problems with an international group of water experts.
