A Tale of Two Sites.

The article provides insights into enhanced bioremediation of explosives impacted soil in the United States. The key to bioremediation method is the use of sequential anaerobic and aerobic conditions, or treatment cycles, generated through the application of proprietary organic and inorganic amendments. The method enhances and promotes natural biodegradation rates by adjusting parameters in a soil or waste matrix to stimulate in situ chemical reduction of target compounds by indigenous microorganisms. Two case studies, the Iowa Army Ammunition Plant and the Yorktown naval weapons station, illustrating the implementation of the method are described.
