Explosions used to be no big deal for residents of sleepy rural towns in north Louisiana's piney woods near the Arkansas border. Blasts meant jobs.
The Army's Camp Minden was the site of a former ammunition factory built during World War II. The factory closed in the 1990s. Still, the place is littered with millions of pounds of leftover artillery waste.
The stuff in question is called M6, a toxic propellant in grenades and artillery rounds. The Army doesn't use it anymore, and tons of M6 are stored in bunkers at Camp Minden.
