Pour la planification des futurs travaux d'assainissement d'un site de stockage de d\u00e9chets dans le canton du Valais, Ecosens SA a accompagn\u00e9 des travaux d'\u00e9chantillonnage complexes. Des d\u00e9chets industriels ainsi que des mat\u00e9riaux de d\u00e9molition et d'excavation ont \u00e9t\u00e9 d\u00e9pos\u00e9s sur le site entre 1938 et 1997. Les d\u00e9p\u00f4ts les plus anciens, en particulier, sont fortement pollu\u00e9s et entra\u00eenent une d\u00e9gradation de la nappe phr\u00e9atique, ce qui n\u00e9cessite un assainissement.<\/p>

En raison des concentrations \u00e9lev\u00e9es de polluants et de la composition des mat\u00e9riaux de la d\u00e9charge, les possibilit\u00e9s de traitement et d'\u00e9limination en Suisse et \u00e0 l'\u00e9tranger sont limit\u00e9es et tr\u00e8s on\u00e9reuses. C'est pourquoi des \u00e9tudes suppl\u00e9mentaires sont men\u00e9es dans le but de d\u00e9velopper des proc\u00e9d\u00e9s de traitement appropri\u00e9s pour pouvoir \u00e9liminer les d\u00e9chets fortement pollu\u00e9s du site de stockage apr\u00e8s leur traitement dans une d\u00e9charge en Suisse.<\/p>

Dans ce but, diff\u00e9rentes entreprises de gestion des d\u00e9chets en Suisse et \u00e0 l'\u00e9tranger ont \u00e9t\u00e9 charg\u00e9es de d\u00e9velopper de nouveaux proc\u00e9d\u00e9s de traitement et d'\u00e9limination de ces d\u00e9chets \u00e0 l'aide de mat\u00e9riel d'essai. Afin de pouvoir mettre \u00e0 disposition ce mat\u00e9riel d'essai, des forages de sondage et des puits de dragage suppl\u00e9mentaires ont \u00e9t\u00e9 r\u00e9alis\u00e9s en hiver 2023. En raison de la pr\u00e9sence d'un b\u00e2timent d'exploitation sur la partie la plus contamin\u00e9e de la d\u00e9charge, l'ex\u00e9cution de ces travaux de sondage a constitu\u00e9 un d\u00e9fi.<\/p>

Gr\u00e2ce au travail de pr\u00e9paration et de planification minutieux de notre \u00e9quipe et aux travaux impeccables r\u00e9alis\u00e9s sur place par l'entreprise de forage et de construction, ces pr\u00e9l\u00e8vements ont pu \u00eatre effectu\u00e9s sans probl\u00e8me. Les r\u00e9sultats de ces analyses sont attendus pour fin 2023, sur la base desquels un projet d'assainissement sera \u00e9labor\u00e9 dans un deuxi\u00e8me temps. \u00a0<\/p>
