Mercury Treatment to Non-Detect Levels at a Former Industrial Site with MetaFix® Reagents

MetaFix was applied at various dosages (0.5%, 1.0%, and 2.0% w/w) to compare field performance of mercury stabilization via SPLP testing.

The treatability study provided insight on the optimal MetaFix reagent formation and dosing recommendations, which were validated by the site pilot study. The MetaFix reagent dosing of 0.5% was selected for the full scale treatment.

The full scale implementation utilizes an integrated soil treatment mixing system where soil crushing/screening and reagent dosing/mixing can be completed in one process per batch. The treated soils are covered and allowed to react for 7 days.
