Ce site a \u00e9t\u00e9 utilis\u00e9 pour l'extraction d'or, et plus de 280 000 tonnes de minerai ont \u00e9t\u00e9 extraites entre 1942 et 1946. Aujourd'hui, il est marqu\u00e9 par la pr\u00e9sence de r\u00e9sidus miniers et de st\u00e9riles accumul\u00e9s dans deux aires distinctes, ainsi qu'une halde \u00e0 st\u00e9riles. Ces r\u00e9sidus, non confin\u00e9s et partiellement rev\u00e9g\u00e9t\u00e9es, n\u00e9cessitaient une \u00e9valuation approfondie de leur impact environnemental. La mission d\u2019Artelia \u00e9tait de caract\u00e9riser ces terrains affect\u00e9s, dans le but de restaurer et s\u00e9curiser ce site abandonn\u00e9, tout en \u00e9valuant la contamination provenant des r\u00e9sidus et des activit\u00e9s mini\u00e8res pass\u00e9es.\r\n\r\nNotre \u00e9quipe a \u00e9t\u00e9 mandat\u00e9e pour mener une \u00e9tude de caract\u00e9risation environnementale compl\u00e8te du site West Malartic. Cette \u00e9tude comprenait une \u00e9valuation environnementale de site (\u00c9ES) de Phase 1 pour \u00e9tablir les objectifs de caract\u00e9risation et dresser un portrait d\u00e9taill\u00e9 des conditions environnementales actuelles. Les travaux ont inclus des sondages de surface, l\u2019\u00e9chantillonnage de sols, d\u2019eau et de s\u00e9diments, ainsi que des essais hydrog\u00e9ologiques pour \u00e9valuer les impacts des r\u00e9sidus et des st\u00e9riles miniers. Les r\u00e9sultats obtenus ont servi ainsi \u00e0 \u00e9laborer un plan de restauration, garantissant la s\u00e9curisation du site et la gestion de la contamination pour une r\u00e9habilitation durable.","Client":"Minist\u00e8re de l\u2019\u00c9nergie et des Ressources naturelles","Lieu":"Rivi\u00e8re-H\u00e9va, Abitibi-T\u00e9miscamingue","villes":"","gallery":null,"domaines_dactivite":"Gestion des eaux industrielles et mini\u00e8res<\/a>\r\n\r\nMinier<\/a>\r\n\r\nRestauration de sites miniers<\/a>"},"yoast_head":"\nCaract\u00e9risation environnementale du site minier West Malartic -
