"This is the third and last portion of land to be turned over for expansion of Danang International Airport," the release said. "The ceremony also marked the completion of the six-year, $110 million Environmental Remediation of Dioxin Contamination at Danang Airport Project, jointly implemented by the United States Agency for International Development (USAID) and MND [Vietnam Ministry of National Defense]."
The project has successfully treated over 90,000 cubic meters of contaminated soil and sediment through thermal desorption and safely contained an additional 50,000 cubic meters of low concentration, dioxin-contaminated material, the release noted.
Since 2000, the United States has worked with Vietnam to resolve humanitarian and wartime legacy issues. These include the removal of unexploded ordinance, the identification of remains of missing personnel and the remediation of dioxin, according to the release.
Dioxin, a virile cancer-causing contaminant, was a key component of Agent Orange, a defoliant widely used by US forces to clear jungle terrain during the Vietnam War.
