Abstract:

For more than 20 years, the Army's Rocky Mountain Arsenal near Denver has been dealing with groundwater pollution caused by chemical warfare agents and pesticides. The arsenal is also a national leader in cleaning up such water. This is done by pumping water out of the ground, running it through activated carbon beds to remove the chemicals, and pumping it back into the ground. A waterproof underground wall�built by the slurry trench method and extending down 30 ft to an impermeable layer�runs more than a mile along the Arsenal's north boundary, preventing the polluted water from leaving the property.
