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.

Performance monitoring conducted showed Pb below the detection limit of 10 ppb, which represents a >97% decrease in soluble Pb. Subsequent monitoring has also confirmed that the injections have been successful in establishing reducing conditions and a significant increase in the aquifer pH from the use of dolomite.
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 Reagents formulation and dosing rate to treat the highly contaminated soil samples.
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.
A lab treatability study was conducted to determine the optimal MetaFix reagent formulation and dosing rate to treat the highly contaminated soil samples with a total arsenic concentration of 21,700 mg/kg.
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.
