Sonia Tarnawski spoke on October 23rd 2020 in the SIPOL CAS. She presented the conditions for using microbiology to assess the remediation potential of a site by biostimulation or natural attenuation. Her presentation was illustrated by the case of a former watchmaking site contaminated with chlorinated hydrocarbons in the canton of Jura.
eOde organized a practical training on the installation of passive samplers in karst springs on September 15 and 29, 2020 in Neuchâtel. The training was supported by the Federal Office for the Environment (FOEN) and could be integrated into the preparation of the SIPOL CAS as an "external course". A practical manual for the [...]
eOde collaborators were at the 4th national research meetings on polluted sites and soils organised by ADEME. Hélène Demougeot-Renard gave a presentation entitled "Geostatistical mapping of sanitary risks for brownfield conversion" and Sonia Tarnawski presented a poster on "An integrative approach for assessing and monitoring the reductive dechlorination of chlorinated ethenes in contaminated aquifers - Treatability [...]
On September 3 2018, eOde organised an introductive short course on geostatistics applied to contaminated sites with the companies DMR and Geovariances, in the context of the nordic meeting on contaminated sites NORDROCS. Around 30 persons involved in the management and remediation of contaminated sites in Danemark, Norway, Sweden and Finland attended the seminar. [...]
From July to September 2018, the freelance consultant expert in environmental microbiology Sonia Tarnawski, made assays for eOde to assess the potential of biodegradation of chlorinated compounds in a contaminated site, at the in situ remediation pilot scaling stage. Various substrates were tested on groundwater and solid matrix samples from the chloroethene-contaminated site, to [...]
eOde is implied in the european JURAD-BAT Interreg project, in collaboration with the HEIA-Fribourg (TRANSFORM institute), on behalf of the Federal office of public health (Radioprotection section). Started in 2016, this french-swiss project aims at better managing the risk of radon and indoor air quality in the new buildings and during energy retrofits. In this [...]
The CHLOROKARST project comes to an end with the Conference "Polluted sites on karst aquifers" organised by the CHYN for the FOEN on 28 June, and the publication by the FOEN of the guide "Assessment of polluted sites in karst environment", as well as the expert report "Investigation tools for polluted sites in karst [...]
In partnership with Soleo Services, eOde will present the conditions for geostatistically assessing the effectiveness of an in situ thermal desorption of a chlorinated hydrocarbons contaminated site, at the annual Chloronet technical day organized by the FOEN. The benefits of geostatistics for assessing and reducing costs of contaminated sites remediation will be shown at [...]
How to reduce the gap between predictions of the amounts of soil requiring remediation - at the diagnostic stage - and those that are actually cleaned up at the remediation stage? This is the main issue that professionals have to face in a large number of brownfields regeneration projects. A study was funded by the [...]
eOde will present the results of passive sampling of 17 springs in the Jura region, at the Intersol conference in Lyon, on 16 March 2017 and at the Aquaconsoil conference in Lyon, on 28 June 2017. Sorbicell passive samplers were exposed during 2 months-periods in karst springs, that are supposed to be hydraulically connected [...]
