• Resumen

  •  On site disposal of "Ex-Situ" solidified contaminated soils. Feasibility tests: whitin site remediation technologies, stabilization / solidification is among the few ones that not only survived but also increased its importance in the last years. We will focus our attention in the case of leaving the "ex-situ" stabilizided soil in place, also the "ex-situ" "on-site" stabilization / solidification. This possibility of "ex-situ" but "on-site" has many advantages and is getting increasing importance, so that for many cases, it has been stablished as prefered alternative by the Ministry of the Environment of Baden-Wüttemberg (Germany) (3). In this paper we will deal mainly with pollution caused by metals. In this paper we will also focus the attention on the most important step in the previous feasibilty study: the lixiviation tests and its application to the risk assesment of stabilized soils
