Abstract
Systems, compositions, and methods for the anaerobic oxidative bioremediation of a contaminant contained within a treatment zone associated with a contaminated region. These systems, compositions, and methods may include a bioremediation formulation that includes a high-mobility oxidant, a low-mobility oxidant, and a nutrient source. The high-mobility oxidant may include a nitrate salt. The low-mobility oxidant may include a sulfate salt. The nutrient source may include brewer's yeast and/or a complex sugar. The bioremediation formulation also may include one or more additional components, including a phosphate salt, a surfactant, a solvent, a chemical oxidant, and/or a bio-augmentation species. Methods of supplying the bioremediation formulation to the treatment zone may include identifying the contaminated region, estimating a mass of contaminant within the contaminated region, determining a bioremediation formulation composition, supplying the bioremediation formulation to the treatment zone, supplying supplemental material(s) to the treatment zone, and/or modifying the environment within the treatment zone.
