*Pollutions are often multiple, with several contaminants from the same family or different families potentially present at the same site. The distribution of all contaminants in the soils or in the aquifers here equals 100 percent. This distribution is defined as a percentage of the total occurrences obtained by a unique combination between a pollutant and a site.

Pollutants in the soils or groundwater of polluted sites and soils in France 2018
The statistic represents the distribution of types of pollutants found in soils and groundwater in the total amount of pollutants. It is noted that for the two environments studied, the types of pollutants are relatively similar in terms of distribution.
It should be noted that groundwater is more likely to contain pollutants other than those listed. They indeed represent ** percent of the pollutants found compared to * percent for soils. On the other hand, soils seem to retain metals as well as hydrocarbons more. However, hydrocarbons remain the most widespread group of pollutants, as they each represent more than half of the pollutants found.
