Inter-comparison of chlorinated solvents fate and transport models

Abstract : The objective of this study is to test different modelling approaches and the reliability of the codes used in water pollution risk assessment for a site contaminated by chlorinated solvents. The final goal is to establish guidelines that may be used as scientific support for contaminated aquifer management. In a first step the models developed by four teams (ANTEA, ENSMP, ENVIROS and INERIS) to simulate contamination of groundwater by perchloroethene were compared (calibrated results, methodology, hypotheses...) to each other. In a second step new data of sorption/degradation lead to notably an improvement of conceptual model and calculated concentrations
