Dioxin contamination at the Da Nang airport is currently being treated with thermal absorption technology from the U.S. This project is expected to be completed in 2016. The Bien Hoa and Phu Cat airports are still in the process of selecting the appropriate technology.
Bien Hoa Airport is the most heavily dioxin polluted. This was the location where the herbicide was stored and pumped into planes during the campaigns known as Ranch Hand (1961-1971) and Pacer Ivy (1971-1972). The volume of contaminated soil and sediment here is about 240,000 cubic meters, three times that of Da Nang Airport, and over 30 times more than what Phu Cat Airport has.
Mr. Son says Bien Hoa Airport is testing a technology known as MCD. After trials, the Steering Committee and experts will select the appropriate technology. The Steering Committee is coordinating with the Ministry of Defense and foreign experts to develop the plan to treat dioxin at the airport.
