In-Situ Treatment Reduces Lifecycle Remediation Costs vs. Pump & Treat


in-situ pfas treatmentThis case study reviews the first known full-scale in-situ PFAS treatment worldwide that was completed in 2016 at a manufacturing and former firefighting training site
in Ontario, Canada, where aqueous film-forming foams (AFFF) were used. A single application of PlumeStop resulted in a significant reduction of contaminant concentrations to below standards for 6+ years since the injection. An independent fate and transport modeling expert predicts that PlumeStop will halt PFAS migration out of the treatment zone for more than 60 years, preventing exposure risk and reducing liabilities for the site owner. Details of the remedial design approach are provided along with results of its implementation.

This case study features the following:

  • PlumeStop application reduces PFAS to non-detect within 3 months, maintaining for six years thus far
  • Remediation company IRSL collects critical treatment zone information to ensure successful application
  • Sampling confirms PlumeStop fully distributed through the treatment zone
  • Modeling indicates that PlumeStop will halt PFAS migration out of the treatment zone for more than 60 years
