Waterbodies provide habitats for plants and wildlife, and recreation areas for the public. They are also a source of drinking water. Today, thanks to protection measures and the expansion of wastewater treatment facilities, the quality of Switzerland's waterbodies is, for the most part, excellent. Micropollutants, however, represent a new challenge and significant revaluation is required in relation to watercourse structure.
Substances from pesticides and pharmaceutical residues (micropollutants) are having an increasing impact on waterbodies. In addition, many watercourses that have been altered by man-made structures need to be restored to a more natural state, so that they can once again serve as species-rich habitats. FOEN seeks to ensure that hazards are recognized in good time and that water resources are preserved for future generations.
