In 2004, Staff Sergeant Susan Clifford was stationed at Balad Air Base in Iraq, where twice a month she was tasked with dumping her unit’s waste products—including human body parts and dead animals—into a dirt pit and setting them ablaze. After a year of breathing the pit’s thick black smoke, her health began to decline. Her lungs filled with fluid, and she soon found she couldn’t engage in strenuous physical activity. She was later discharged from the Army with full disability. Clifford’s story, as New York Times journalist James Risen reported in 2010, was typical of a class of new disability cases that appeared to be linked directly to the burn pits set up across Iraq and Afghanistan by a subsidiary of Halliburton. Risen’s article led the Institute of Medicine (IOM) to publish a report on the long-term health consequences of exposure to burn pits, which clearly confirmed the linkage between the pits and debilitating illnesses affecting service personnel returning from the Middle East. But, in the years since, the media has largely ignored the issue. Last week, I caught up with journalist Joseph Hickman, whose new book, The Burn Pits, tells the story of thousands of U.S. soldiers who, after returning from Iraq and Afghanistan, have developed rare cancers and respiratory diseases.
