Mapping the dioxins and furans soil pollution in Lausanne

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 [...]

Emerging pollutants: only PFAS ?

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 [...]

GIS methodology for inventory and indicative mapping of potentially polluted soils at the scale of a municipality, a district or a canton

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 [...]

A toolbox to facilitate geostatistical calculations of Pareto-Soil mass balances

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 [...]

Identification of possible sources of dioxins and furans pollution by multivariate statistical analysis

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 [...]

Tailored trainings in geostatistics applied to contaminated sites and urban soils

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.

Direct measurement of flux and estimation of mass flow of chlorinated hydrocarbons by passive flow samplers

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 attending the REMTECH EUROPE 2021 conference

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 [...]
