The reduced oil produced water is introduced to the iron sponge, and the iron sponge removes a portion of the hazardous sulfides from the reduced oil produced water to provide a reduced sulfide produced water. The system also includes a stabilized sodium percarbonate solution. The stabilized sodium percarbonate solution is mixed with the reduced sulfide produced water to remove a portion of the hazardous sulfides from the reduced sulfide produced water to provide a treated produced water.
