The Radford Army Ammunition Plant has been making and testing munitions for more than 70 years, and burning toxic waste from the process, outdoors, for just as long. But while a few Department of Defense installations have either ended the practice or adopted cleaner technologies, the timeline for doing so in Radford remains vague. New pollution data and national attention to the problem are energizing the community and the Arsenal staff toward a solution, but the ‘burning question’ remains.
