Soil contamination by dioxins in the city of Lausanne: investigations, remediation 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.
Remediation of Solothurn's municipal manure landfills - Ecosens investigates underlying contamination
Between 1925 and 1976, the city of Solothurn disposed of waste on the "Stadtmist" in the agricultural area to the west of the city. The three landfills "Unterhof", "Spitelfeld" and "Oberer Einschlag" were created as a result of this disposal. The landfills are spatially separated by the two streams Brunngraben in the west and Brühlgraben in the east.
Air tightness measurements with blower door measurement method
In well-insulated buildings, up to 60 % of heating energy can be lost through gaps and cracks in the building envelope. Energy-efficient construction can therefore only be achieved with a high degree of airtightness of the building envelope. In addition, this prevents structural damage due to condensation as well as the penetration of drafts, noise or odors.
GI Good indoor climate
The GI GUTES INNENRAUMKLIMA® label offers building owners security with regard to the indoor climate in new buildings and conversions as well as in existing buildings. To obtain the label, qualified measuring institutes check that the highest standards of indoor air quality are met.

Neophytes in the Valais Alps
Neophytes are alien plant species that were introduced after 1500 and have become established in the wild. These include popular garden plants such as the vinegar tree, the summer lilac or the cherry laurel. Invasive species spread so rapidly that they displace other native species that are characteristic of the habitat in question, which can lead to a decline in biodiversity.
Significant change in practice by the Federal Supreme Court regarding entries in the register of contaminated sites
At the end of the 1980s, two landowners in the canton of Thurgau, with the permission of the then Office for Environmental Protection and Water Management, had garbage slag installed on their land, e.g. to pave paths and areas for plant containers.
Rynetel wildlife transfer
Wildlife corridors are part of the ecological infrastructure. The AG6 wildlife corridor in the Rohr-Rupperswil forest area is one of the most important in Switzerland. The wildlife overpasses aim to create a trouble-free network of paths for wild animals across cantonal borders.
Ecosens AG processes PFAS contaminated sites
Investigation and remediation of suspected sites with the emerging pollutant group PFAS (per- and polyfluorinated alkyl compounds). The substances in the PFAS (per- and polyfluorinated alkyl compounds) group are chemically, biologically and thermally very stable due to their structure.
The lead on the mountain goes into the money - Shooting range Hittenberg
Municipality of Wald - The municipality of Wald has had to rehabilitate four bullet traps. Now the contaminated sites have also been dredged at the Hittenberg facility, which has been shut down for some time. A particular challenge was the demanding topography.
