General objectives

Groundwater under pressure

Groundwater is a valuable resource that must be protected, since in Switzerland ~80% of drinking water is obtained from groundwater (incl. spring water). Particularly powerful groundwater deposits are often located along large river courses, which often represent heavily populated areas of Switzerland. Contamination from various sources, anthropogenic influences on the hydrogeological system, and climate change have a major impact on groundwater quality and quantity. In order to grasp and better understand hydrogeological issues and challenges under the pressure of new developments and to work on missing basics, there is a great need for a continuous competence building, technical support and a smooth Switzerland-wide exchange between research and practice. To make a significant contribution to this, the CH-GNet network was created.


Main goal

The primary aim of CH-GNet is to publicise existing research in the field of groundwater and related disciplines and to create a forum for exchange, information and networking. We see ourselves as a link between practice-orientated and basic research.

Further goals

  • To process information and findings from science and make them available to practice. Achieve strong practice-oriented research by investigating groundwater-related problems and developing principles for practice.
  • Organize workshops, webinars, and continuing education.
  • Promote continuous skill building and a smooth exchange of information.
  • Contact point for concerns of the practice to the research.

Through the work of the CH-GNet, the current but also future research central questions are to be made "explicit". Information, developed tools and findings from science are processed and made available to practice. This represents a contribution of research and CH-GNet to society.  Purely scientific facts are developed for the respective main topics. The support of the practice are central here. In the long run, the visibility of groundwater research and the exchange with practice in Switzerland shall be increased.
