Does my pollution pose a risk? Following the identification of a pollution, you must assess whether it poses a risk with a view to determining, according to the applicable legislation, the urgency or the need for remediation. Hydreau conducts these risk assessments, both in terms of data acquisition and studies. Hydreau has extensive experience in health risk assessment and groundwater (leaching and migration) where we combine this expertise with our knowledge of groundwater management.

Soil pollution is characterized by several factors that will influence the selection of the best remediation technique. These factors are either inherent to your site (type of geology, depth of groundwater, built-up areas, etc.) or inherent to the actual pollution (type of contaminants, possible mixtures, pollutant content). The best remedial method generally consists of a combination of techniques that can either eliminate pollution or eliminate risks by acting on the transfer routes between pollution and its receptor.
