Bioremediation systems, compositions, and methods

A method of decreasing a concentration of a contaminant contained within a contaminated region, the method comprising:

• supplying a first bioremediation formulation that includes an ion exchange resin to a first treatment zone that is associated with the contaminated region;
• and
• supplying a second bioremediation formulation to a second treatment zone that is associated with the contaminated region, wherein the second bioremediation formulation includes a high-mobility oxidant, a low-mobility oxidant, and a nutrient material.

A kit of bioremediation formulations to be utilized during the bioremediation of a contaminated region, the kit comprising:

• a supply of a first bioremediation formulation for being supplied to a first treatment zone that is associated with the contaminated region, wherein the first bioremediation formulation includes an ion exchange resin;
• and
• a supply of a second bioremediation formulation for being supplied to a second treatment zone that is associated with the contaminated region and that is at least partially coextensive with the first treatment zone after the first bioremediation formulation is supplied to the first treatment zone, wherein the second bioremediation formulation includes a high-mobility oxidant, a low-mobility oxidant, and a nutrient material.
