The Balad burn pit occupies approximately 10 acres. The burned waste products include, but are not limited to: plastics and Styrofoam, metal/aluminum cans, rubber, chemicals (such as, paints, solvents), petroleum and lubricant products, munitions and other unexploded ordnance, wood waste, medical and human waste, and incomplete combustion by-products. Jet fuel is used as the accelerant. The pits do not effectively burn the volume of waste generated, and smoke from the burn pit blows over the Air Base and into living areas. DoD has reported to VA that as of October 2009, the Balad burn pits were shut down and incinerators were installed. Burn pits still operate at many other bases.
