Session 24: Bioremediation of explosive-contaminated soil and water
Wednesday, July 27, 2016: 8:00 AM-11:30 AM
Grand Couteau, 5th Fl (Sheraton New Orleans)
Raj Boopathy - Nicholls State University and Karl Indest - US Army Corp of Engineering
In the US, every state has at least one army ammunition plant with many thousands of acres that are contaminated with explosives and propellants from many decades of unregulated disposal of contaminants. Most of these plants are in caretaker status and the army has to clean up the land before it can give it back to local government for various uses.  There are several ground-breaking discoveries in the bioremediation of explosive-contaminated soil and water by many researchers. In this session speakers will share their recent discoveries in this field.  The research includes basic to applied to solve the real world problem of cleaning up the contaminated soil.
