56,941 ABSTRACT OF THE DISCLOSURE A method for stabilizing in-situ soluble heavy metal contaminants in carbonate-containing land or submarine formations which comprises introducing into the carbonate- containing formation an aqueous solution of calcium chlor- ide, wherein the solution contains a stabilizing amount of calcium ions. The contaminants and the carbonate form coprecipitates with the calcium ions which are insoluble in formation fluids, therefore substantially inhibiting the remobilization of the heavy metals with groundwater. The method is effective with heavy metals which exist in both anionic and cationic form in carbonate-containing land or submarine formations. The method may be used to treat land formations hundreds of feet below the surface, landfill deposits, or submarine formations to reduce soluble heavy metal contaminants to a few parts per million.
