Do contaminants sorb to oil preventing biodegradation?
EOS® treatment results in a small temporary increase in sorption of the contaminants into the oil phase, a clearly beneficial effect. Biodegradation does not occur in the oil, but can retard migration of the contaminant, especially DNAPL. Years of laboratory and field research have proven that, over time, contaminants are eventually released back to aqueous phase as biodegradation proceeds. The contaminants are then more susceptible to degradation in the newly enhanced environment.
