5.8 Diluting soil contaminants
By diluting the concentration of the pollutant in order to facilitate degradation processes, a more even distribution of contaminants can be achieved throughout the soil profile, thereby lowering contaminant concentrations. This can help improve the conditions for vegetation establishment and growth, thereby supporting ecosystem recovery. However, this approach may not eliminate all contaminants and may pose risks of spreading pollutants. Therefore, it is often combined with other remediation strategies, such as bioremediation, to effectively restore soil health.
