September Member Presentation (IN PERSON)

Enhanced in-situ bioremediation (EISB), a cost-effective approach to treat source areas under ongoing industrial land use

EISB – Why put in the effort, with people and machinery, when there’s a willing ‘work-force’ out there to clean up your site for a free feed? 

EISB involves the addition of organic substrates to stimulate microbial activity for enhanced degradation of various organic contaminants in the subsurface. As the injected organic substrate biodegrades, it releases fatty acids into the groundwater that ferment and release hydrogen, which can be used by dechlorinating bacteria. The bacteria degrade chlorinated solvents by stripping chlorine atoms from the chlorinated organic molecule, replacing each with a hydrogen atom and releasing chloride. During the presentation, we will discuss the general concepts and techniques of implementing EISB, its implementation in the field and what clients think about it.”
