Claim:
1. A process of making a solid encapsulated reactant and treatment of a subterranean zone of contamination which is contaminated by a target contaminant, the process comprising: preparing an encapsulant by melting a mass of the encapsulant to convert the encapsulant to a non-solid state thereby making a prepared encapsulant; combining a plurality of reactant particles with the prepared encapsulant and coating the plurality of reactant particles with the prepared encapsulant thereby making an encapsulated reactant having a plurality of reactant particles therein; cooling the encapsulated reactant to produce the solid encapsulated reactant, wherein the solid encapsulated reactant is of sufficient size and mass such that it and does not flow through the subterranean zone of contamination; placing the produced solid encapsulated reactant in the subterranean zone; and substantially maintaining the placement of the produced solid encapsulated reactant in the subterranean zone for the treatment of the target contaminant.
