Inter-comparison of chlorinated solvents fate and transport models

International audienceThe 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 concentration
