In regard to the SNOWMAN research program in the field of soil-water-groundwater systems with respect to contamination, the main objective of the MuSA project is to propose methodological improvement for a decision support tool bringing together Environmental Risk Assessment (ERA) and Life Cycle Assessment (LCA) for contaminated soils management. In order to achieve this aim the work was divided into (1) Improving multiple scale ecological risk assessment and Life Cycle Assessment of contaminated land, (2) Improvement of the understanding of the modelling of
the mobility and bioavailability of metals in soils, and (3) the Ronde-Venen Case Study in order to (i) ensure
the applicability of the developments; and (ii) proposing an illustration of the use of the propose sustainable
land management in order to facilitate the understanding of users. The development of a decision support tool especially responds to a need of soil resource management
authorities for scientifically sound methods permitting the ecological risk assessment of contaminated soil at
different spatial and temporal scales in order to have a better perception of the environmental impacts associates with the management strategy of the contaminated soils.
