In the field of contaminated sites and soils management, uncertainties are present at all levels, in sampling, analyses, data interpretation, estimations, mapping, and even communication between stakeholders. What impact can they have on the management of the site? And how to manage them? Watch this recorded webinar to find out.
When mapping and quantifying the volumes of polluted soil to be treated on a site, one may wonder about the reliability of the map or the figures obtained. How often do rehabilitation works reveal pollution levels that were not foreseen or in locations not envisaged?
Various sources of uncertainty can impact the quality of the information and be at the origin of this difference between estimations and reality:
– Historical studies’ quality,
– Soil heterogeneity,
– Samples’ representativeness and location,
– The sampling or analysis techniques,
– The maps that use these non-exhaustive, sometimes insufficient, or redundant data, depending on the accessibility of the site,
– The interpretation and mapping methods that necessarily imply calculation assumptions and the choice of the parameters used.
Geostatistics can help you better understand and manage data and mapping uncertainties. Claire Faucheux, our senior consultant expert in contamination characterization, explains it to you.
