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 [...]
We assist project owners in the management of polluted sites and soils
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, [...]
