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 :

• Creating GeoSiPol – workshop for promoting the use of geostatistics for assessing site contaminations
• Writing fact sheets and a methodological handbook for GeoSiPol
• Critical feedback on 15 years of geostatistics applied to contaminated sites for RECORD
• Feedback on the predictions of soil quantities requiring remerdiation for 23 former industrial sites for RECORD
• Review of the chapter dedicated to geostatistics in the UPDS handbook on toxic hotspots
• Numerous training sessions for contaminated sites specialists (CAS SIPOL, Aquaconsoil 2015, eOde-Geovariances workshops, etc.).
