Metals Remediation Compound (MRC™) is a controlled release product that simultaneously removes a range of dissolved metals from groundwater via in-situ immobilization and provides substrate for biodegradation of chlorinated compounds. MRC is simply injected into groundwater where once hydrated it becomes subject to microbial biodegradation. While being degraded it slowly releases its active ingredient, a benign organosulfur compound (BOC). Upon contact with metal ions, the BOC reacts to produce a metal-organosulfur complex. This complex sorbs strongly to soil and is immobile in the subsurface. Over time the organic portion of the metal-organosulfur complex is also biodegraded and the complexed metal is incorporated into the soil matrix as a sulfide solid. The BOC can also act as a direct reductant for metals like chromium and uranium that precipitate as hydroxides and oxides. MRC also provides a substrate similar to that of HRC for accelerated reductive dechlorination of chlorinated compounds making it highly suitable for mixed plumes containing both metals and chlorinated contaminants.
