20130260441 | BIOREMEDIATION SYSTEMS, COMPOSITIONS, AND METHODS - Systems, compositions, and methods for the bioremediation of a contaminant contained within a contaminated region. The systems, compositions, and methods may include supplying a first bioremediation formulation that includes an ion exchange resin to a first treatment zone that is associated with the contaminated region. The systems, compositions, and methods further may include supplying a second bioremediation formulation that includes a high-mobility oxidant, a low-mobility oxidant, and a nutrient material to a second treatment zone that is associated with the contaminated region. The systems, compositions, and methods also may include a kit of bioremediation formulations that includes the first bioremediation formulation and the second bioremediation formulation and is to be utilized during the bioremediation of the contaminated region. | 10-03-2013 |
20120252102 | BIOREMEDIATION SYSTEMS, COMPOSITIONS, AND METHODS - 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. | 10-04-2012 |
