From 1962 to 1971, the American military sprayed vast areas of Vietnam with Agent Orange, leaving dioxin contamination that has severely affected the health of three generations of Vietnamese. Now, the U.S. and Vietnamese governments have joined together in a massive cleanup project.
In the thriving industrial city of Bien Hoa, about 20 miles east of Ho Chi Minh City, the former Saigon, there is a large air base, just beyond a sweeping bend in the Dong Nai River. During the American war in Vietnam, it was said to be the busiest airport in the world.
