Dechlored : development and in situ implementation of a chemical process for the reductive dechlorination od chlorinated solvents in polluted groundwater
Résumé
This study is accomplished within the framework of DECHLORED, a project financed by ADEME, the French Agency for the Environment and Energy Resources (Eco-Industries 2011 program). This project aims to : i) develop and prove the efficiency of a novel in situ chemical reductive dechlorination (RDC) process of chlorinated solvents (CSs) in polluted aquifers by using strong reducers (Sodium Dithionite, DT) with or not the combined effect of Nano-sized zero-valent iron particles (NZVI), and ii) illuminate, by an improved monitoring, the field under RDC process. The purpose of the present communication is to present the work accomplished to set up an enhanced procedure for the reductive dechlorination of CSs in polluted aquifers and performed not only in batch and column experiments but also as in situ demonstration.
