6. Impact control

6.1 Impact delimitation

Once the source of pollution has been identified, its impact on all environmental media must be assessed:

• precise extent of the pollution source's impact (horizontal, vertical, high water, low water, soil heterogeneity, preferential path);

• evolution over time (maximum reached...) ;

• concentrations upstream, downstream, at right off site ;

• groundwater and surface water :

  • release potential of...
