eOde is involved in a wide range of activities related to environmental data analysis, from data processing to modeling, using statistics, geostatistics and GIS (software and computer languages : Matlab, R, Isatis, Isatis.neo, Kartotrak, AR2Tech-SgeMs, QGis).

In contaminated site studies, eOde maps in 2D or 3D highly polluted zones, designs sampling plans, estimates volumes of contaminated soil or groundwater, establishes initial soil volume and pollutant mass balances (Pareto-sol method) and final residual pollution amounts after treatment. eOde also provides targeted support to offices carrying out their own geostatistical studies and actively participates in the development of new methodologies through various research projects, such as REPERAGE or CARTORISK.

For the past 5 years, eOde has been requested to develop methodologies for mapping the pedogeochemical background of urban soils based on chemical analyses of solid samples, and to draw up indicative maps of soils at risk of pollution based on geodata, at the scale of a municipality, a district or a canton.

eOde is a historical actor of geostatistics of polluted sites, with an active participation for more than 20 years in the implementation of pragmatic approaches adapted to the reality of sites investigation and remediation in France and Switzerland. eOde has contributed to many training and information actions, such as :




Consulting offices, project owners, public agencies

  • Geostatistical studies
  • Supervision and support to perform geostatistical studies
  • Tailored training
  • Applied research projects
  • Computer programming

Major benefits of geostatistics

  • Mapping various spatio-temporal phenomena
  • Assessing volumes of contaminated materials and related uncertainty
  • Assessing in situ masses of pollutants and related uncertainty
  • Optimizing sampling campaigns
  • Using diverse data in modeling in order to reduce uncertainty
  • 3D visualization and communication tools
  • Synthesis and analysis of data
