The TCLP and water leaching studies demonstrated significant stabilization effect of the leachable arsenic. MetaFix reagent dosing as low as 2% achieved a 99% stabilization effect, even by the stringent TCLP testing protocol. Water leaching concentrations dropped from 41.6 mg/L to 0.19 mg/L with MetaFix applied at a 2% dosing rate. This meets the entry standard of Class One industrial sold waste landfill, thus, significantly reducing its disposal cost and environmental risk.
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.

A lab treatability study was conducted to determine the optimal MetaFix reagent formulation and dosing rate to treat the four heavy metals of concern: As, Cd, Pb, and Zn.
EHC Metals Reagent is now a part of the MetaFix portfolio of customizable reagents. EHC Metals effectively treated TCE and immobilized Cr(VI) from groundwater to below detection limits at a manufacturing facility in Washington state.
EHC Metals Reagent is now a part of the MetaFix portfolio of customizable reagents. EHC Metals Reagent has been shown to effectively immobilize lead (Pb) from groundwater at a former battery recycling facility in Brazil.
