A planned House hearing comes in the wake of a series of explosions and fires that have killed and injured nearly a dozen workers at munition plants in recent years and led to a previously unreported investigation by the House Armed Services Committee.
The inspector general for the U.S. Department of Defense has launched an investigation into the open burning of ammunition and explosives at military sites across the country, including at a sprawling Army ammunition plant in Virginia.
Researchers who flew a drone over the open burning of hazardous waste at an Army ammunition plant in Virginia found arsenic, lead and other pollutants at higher-than-expected levels, according to a draft report obtained by The Associated Press.
