General goals

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, so that conflicts of interest can hardly be avoided. 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 hydrogeological issues and challenges under the pressure of new developments, to develop solutions and measures and to implement them, there is a great need for a continuous competence building, technical support and a smooth Switzerland-wide exchange between research and various stakeholders. To make a significant contribution to this, the CH-GNet network was created.



Specific goals

  • Contact platform for groundwater topics.
  • Offering clarifications of questions from practice with the latest methods from research.
  • Bundle practice-relevant research results and tools and make them visible.
  • Bundling of questions from the cantons, organization of workshops on groundwater topics and implementation of cross-cantonal projects.
  • Provide advice and arrange contacts with research institutions.
  • Increase visibility of groundwater research and exchange with practitioners.
  • Be a source of information and promote knowledge transfer and exchange.

Through the work of the CH-GNet, the current but also central future research questions and especially solutions should be made "explicit". This represents a contribution of research and CH-GNet to society. CH-GNet sees itself as a "think tank", whereby one of the most important functions of CH-GNet is the dissemination and explanation of research results as well as the setting of concrete thematic priorities. Purely scientific facts are compiled for the respective main topics. The promotion of a public and scientific debate and the support of the practice are central here. Through this, a strengthening of research advice has to take place. Among other things, this should increase the visibility of groundwater research and the exchange with practice in Switzerland in the long term.

      Webinar series - Groundwater protection in Switzerland: Interaction of agriculture, water supply, research, cantons and authorities

      Webinar series - Groundwater protection in Switzerland: Interaction of agriculture, water supply, research, cantons and authorities organized by the Swiss Groundwater Network (CH-GNet) on 31.05.2022 from 13:00 -14:00.

      Rainer Hug is a scientific expert in groundwater protection / water supply at the Office for Environment in the canton of Solothurn as well as Project Manager of the Nitrate Project - Niederbipp - Gäu - Olten, the largest nitrate project in Switzerland and will give a presentation based on 3 theses followed by a question and discussion session. The theses for this lecture are:

      1. The current agricultural practice leads to high nutrient losses into groundwater, adapted management measures and complete nutrient balances are needed.
      2. Agriculture must adapt to the hydrogeological conditions.
      3. Agriculture and water supply, a community of destiny.

      The event will be held online via Zoom. You will receive the necessary information to participate in the pdf (click on the document below) or by mail (subscribe to newsletter).
