Compositions, methods, and systems for reducing contamination
Certain exemplary embodiments provide methods for reducing a concentration of a contaminant associated with a medium, which can be any substance or material, such as soil, water, air, and/or fluid. In one exemplary method, the medium is treated with a ferric chelate and an oxidizing agent in amounts effective to oxidize at least a portion of the contaminant.

a mixture of:
ferric gluconate, wherein all chelation sites of the ferric gluconate are saturated with ferric ion, and wherein a concentration of the ferric ion is between 3570 ppm and 22,200 ppm; and
an oxidizing agent.
2. The composition of matter of claim 1 , further comprising reactive oxidants that result from mixing the ferric gluconate and the oxidizing agent.
3. The composition of matter of claim 1 , further comprising free radicals that result from mixing the ferric gluconate and the oxidizing agent.
4. The composition of matter of claim 1 , wherein the mixture is in contact with a contaminant associated with a medium.
5. The composition of matter of claim 1 , wherein the mixture is in contact with a medium and a contaminant associated with the medium, the mixture adapted to generate reactive oxidants effective to oxidize at least a portion of the contaminant, an amount of said reactive oxidants greater than an amount of reactive oxidants available from said oxidizing agent alone.
6. The composition of matter of claim 1 , wherein the mixture is in contact with a medium and a contaminant associated with the medium, the medium is selected from soil, water, air, a fluid, a solid, and a surface.
