Sulfate, magnetite, sheep, and chlorinated solvent bioremediation,
Environmental remediation is both challenging and rewarding since it requires multiple skill sets to solve complex environmental problems.
Recently, OBG took on the challenge of finding a remedial solution for trichloroethylene in a fracture bedrock environment containing high sulfate groundwater. Bioremediation was the technology of choice; however, the presence of the high sulfate created a significant impediment to success. The answer came through combining two novel approaches using magnetite powder and vitamin B12 and a delivery method developed to treat vitamin deficiency in New Zealand sheep.
