Abstract
The uncontrolled management of solid and liquid waste from chemical wo rks and metallurgical industries caused the pollution of numerous area s in the alpine regions. The high permeability coefficient allowed the infiltration of polluting agents of the groundwater level and their d ispersion downstream. The restoration of hazardous waste sites in the upper Rhone river valley demonstrated that: hydrogeological evaluation s are essential to understand the infiltration and the transport of th e polluting agents; they are essential to assess the efficiency of a d econtamination or a stabilisation process on the environment; modellin g approaches have to be considered cautiously; the controlling factors and decision making criteria have to apply to every situation.
