In 2021, we have been mandated by the canton of Vaud to map the potential for dioxin and furan soil pollution in the commune of Lausanne and its neighboring communes. We have modeled the spatial distribution of the pollution from soil samples collected by Impact-Concept, as well as from other data collected by the [...]
In recent years, professionals working with polluted sites and soils have been concerned with “emerging pollutants”, substances that are not yet regulated, although they are often already known, and which are the subject of a recent awareness of the threat they pose to humans and their environment. Analytical capacities have indeed progressed, as has [...]
In 2020 and 2021, several mandates have been entrusted to us to develop an inventory methodology of potentially polluted soils that could present a health risk for the population, especially young childrens. The objective of the authorities is to have indicative soil maps of chemical pollution risks at the scale of a municipality, a [...]
In 2021, we have developed a toolbox to accelerate the calculation of mass balances according to the Pareto-Soil method from geostatistical pollution models. The modelling results are processed in scripts in which the calculations are automated: they can thus be repeated easily for different variants, by modifying for example the thresholds of applied contents [...]
Multivariate statistical analysis of data characterizing pollution is one of the environmental forensic methods used to search for scientific evidence of the origin of pollution. In 2021, we applied this approach for the canton of Vaud to the analysis of dioxins and furans in soil samples collected in the commune of Lausanne and its [...]
For many years we have been supporting project owners in the execution of their tasks. As BAMO, we support them throughout their project as competent experts in the field of polluted sites and soils. We complement the skills and availability of the project owner, for technical expertise or to ensure the management of projects, [...]
eOde proposes tailored trainings in geostatistics applied to contaminated sites and urban soils. In 2018 for example, eOde delivered an in-house 1-day course to the project managers of ADEME at Angers, while in 2014, eOde organized a 3 days-course for the equip of Envisol in the Rhônes-Alpes region.
eOde wishes you all the best for 2022!
Direct measurement of flux and estimation of mass flow of chlorinated hydrocarbons by passive flow samplers Fluxes and mass flow rates are key elements in the assessment of the effect of pollution sources on groundwater. These values are also useful for the definition of remediation measures at a site, by specifying the location of [...]
eOde is pleased to attend the international REMTECH conference on September 21, 2021! iFLUX and eOde will present chlorinated ethenes mass flux measurements and mass discharge estimated from a high resolution characterization of a contaminated site in a contrasting hydrogeological context. The USEPA considers that High-resolution site characterization (HRSC) is one of the promising [...]
