An In Situ Microcosm study was conducted to evaluate MNA vs. enhanced aerobic bioremediation at a petroleum impacted site.
Site managers asked: “Will the injection of an oxygen releasing compound stimulate BTEX biodegradation at this site?” The answer was yes. The ISM study showed conclusively that injection of the an oxygen releasing compound at the site will increase the growth of BTEX degraders and stimulate BTEX biodegradation under aquifer conditions.
The ISM study conducted at this site provided clear, actionable evidence that increasing the dissolved oxygen concentration at the site would stimulate hydrocarbon biodegradation. Further, this evidence was provided in a significantly more cost effective manner than a bench-scale treatability study or a pilot scale study and in a more timely manner.
