Conceptual framework

– Presence of a condition caused by heavy metals resulting from accidental leaks from the industrial process network.
– Need to delimit the impact of metals in the underground environment and proceed with the environmental improvement.

Performances

  • Delimitation of metal affection:
    Execution of characterization campaigns of the underground environment to delimit and enclose the condition detected by heavy metals in ZNS and ZS.
  • Certification of origin of organochlorine condition:
    Development of research campaigns and characterization of the underground environment, determining that the origin of the organochlorine condition detected on the site is unrelated to the industrial activity in progress.
  • Development of pilot test for the treatment of ZNS:
    Laboratory test for the feasibility and sizing of the injection of the bentonite gel for confinement of metals in an unsaturated zone.
  • Development of pilot test for the treatment of ZNS:
    Laboratory test for the feasibility and sizing of the metal treatment unit water using a pumping system and treatment by coagulation/flocculation/decantation.
  • Full scale underground remediation for the treatment of contamination due to the presence of heavy metals.
