Online platform Water assessment tools

The platform serves to provide online calculation tools for determining the ecological quality of water bodies and is operated by Aquatic Ecology on behalf of the Federal Environment Agency. At the moment the platform is only available in German, but other languages are possible and might come in the near future.
