EWMA has a long history of applying innovative remedial technologies to benefit our clients. The latest being utilized by EWMA is the design and application of enhanced anaerobic bioremediation technologies to completely degrade chlorinated solvents in groundwater. A conceptual enhanced bioremediation program would typically consist of biostimulation (addition of a food grade amendment, such as emulsified vegetable oil, to serve as an electron donor and to stimulate biological activity) with possible bioaugmentation (supplemental addition of specific bacterium, if necessary). The resulting fermentation reactions create an environment highly favorable for the rapid dechlorination and subsequent remediation of the chlorinated solvents in the groundwater.
