New publication: Use of environmental DNA to monitor aquatic ecosystems

What are the advantages and disadvantages, what methods are available, and what best practices and routine standards should be applied? These questions can all be answered by these guidelines on the use of eDNA methods for the biological analysis and evaluation of aquatic ecosystems.

Bathing water quality

EEA report on bathing water quality 2019

08.06.2020 - Thanks to various protective measures and major advances in wastewater treatment in recent decades, water quality in Swiss rivers and lakes is now very high and virtually all are clean enough to swim in.

'Rhine 2040' programme adopted

'Rhine 2040' programme adopted

13.02.2020 - The 16th Conference of Rhine Ministers was held in Amsterdam on 13 February 2020. It successfully adopted the 'Rhine 2040' programme, with its new and ambitious targets for biodiversity (the return of migratory fish), water quality (a reduction in micropollutants), climate change, flood defences and measures to deal with low water levels.


Plant protection products


High concentrations of plant protection

The "NAWA SPEZ 2017" study examined the impact of plant protection products in five small water courses. The study revealed that creeks are affected commonly in regions with intensive agriculture.

Water flow and flow regime

Water supply depends on natural factors and is influenced by hydropower production and climate change. The FOEN is monitoring the water flow and flow regime of Swiss bodies of water. 

Monitoring data and statistics

Current monitoring data on bodies of water, the possibility of obtaining data, information about extreme value statistics and data on the water withdrawn and returned

State of waterbodies

Despite the generally good quality of its water, residues from fertilizer and plant protection products, chemical residues from wastewater, as well as man-made structures and artificial obstacles damage surface and underground waters.

Ground water

Good quality groundwater is available in sufficient quantities almost everywhere in Switzerland. Traces of artificial, rather persistent substances are found mainly below cropland and in settlement areas.
