Reusing former industrial sites is a challenge due to high costs generally necessary to waive all risks for humans and ecosystems.

As our knowledge about the spatial distribution of the pollution is always fragmentary, models are needed to obtain the best possible pollution levels estimates and to quantify the associated uncertainties.

Ephesia has more than 10 years of experience in assisting public agencies and soil assessment companies in the geostatistical modeling of polluted sites. The objective is to offer the most relevant decision aid tools such as:

  • Multi-pollutants 3D maps
  • Quantification of the probability to exceed regulation or safety thresholds
  • Real-time update of the current maps with in situ measurements
  • Uncertainty quantification
