A propos de ce projet :<\/span><\/h3>\n[\/vc_column_text][vc_column_text css=\u00a0\u00bb\u00a0\u00bb text_direction=\u00a0\u00bbdefault\u00a0\u00bb]Un essai pilote a \u00e9t\u00e9 mis en place sur un site contamin\u00e9 afin d’\u00e9valuer la faisabilit\u00e9 de la d\u00e9chloration r\u00e9ductrice du 1,2-dichloropropane \u00e0 des concentrations \u00e9lev\u00e9es (>1.000 mg\/L). Plusieurs injections d’une source de carbone sont effectu\u00e9es en combinaison avec des traceurs (bromure et fluoresc\u00e9ine) \u00e0 une profondeur de 21 m\u00e8tres. <\/p>\n

Pendant le processus d’injection, le d\u00e9bit et la pression sont contr\u00f4l\u00e9s en permanence. La distribution du liquide d’injection est cartographi\u00e9e \u00e0 travers 18 puits de surveillance environnants. Le traceur utilis\u00e9, la fluoresc\u00e9ine, s’av\u00e8re particuli\u00e8rement utile pour confirmer visuellement l’arriv\u00e9e de la solution d’injection dans les puits de surveillance. <\/p>\n

Il est frappant de constater que la direction de l’\u00e9coulement, mise en \u00e9vidence par les traceurs, s’\u00e9carte d’environ 30\u00b0 du gradient attendu des eaux souterraines – un fait important pour la conception de l’assainissement \u00e0 grande \u00e9chelle. Plusieurs analyses sont effectu\u00e9es pour d\u00e9montrer la biod\u00e9gradation :[\/vc_column_text]
