Da Nang International Airport will be completely free of dioxin pollution by 2013, according to an official of the Vietnamese Ministry of Defense

Dr. Pham Dinh Chien, head of the Department of Science, Technology and Environment of the Ministry of National Defense, said this at a conference between the United States Agency for International Development (USAID) and the Ministry of Defense on January 13.

The conference was held in the central province of Da Nang for the sole purpose of finding a solution to tackle dioxin pollution at Da Nang International Airport.

A proposed US$34 million project to decontaminate the airport will be conducted in two phases from the third quarter of 2011 until 2013. 

USAID experts said the in-situ thermal desorption (ISTD) alternative was feasible at the Da Nang site. The ISTD technology uses direct application of heat, supplied by electrical heating elements, to raise the temperature of the soil in-situ thus destroying the organic contaminants. Soil and sediments contaminated with dioxin are placed on a thermal blanket which is heated to 300 degree Celsius to destroy all toxic elements. Soil thus treated would then be safe for planting and breeding.
