Soil contamination by dioxins in the city of Lausanne:

Investigations, refurbishments and cost allocation

On January 19, 2023, the canton of Vaud held a press conference to announce the results of the new soil tests in connection with the dioxin contamination discovered in Lausanne in 2021. Around 4,000 plots of land need to be further investigated and checked for their need for remediation, particularly in the case of construction projects or conversions to existing buildings. In the meantime, the canton - together with the Federal Office for the Environment (FOEN) and the city of Lausanne - is launching pilot projects to find out how the soil can best be remediated. The question of who will ultimately have to bear the costs of measures has not yet been clearly answered by the authorities.

Here you will find the Perimeter in Lausannein which additional soil investigations must be carried out to assess the need for remediation.
