The United States Agency for International Development (USAID) said it will begin work on cleaning up Agent Orange/dioxin contamination at Da Nang Airport in Vietnam.
The US will spend US$43 million to use In-Pile Thermal Desorption (IPTD) technology to rid the airport soil of dioxin, Donald Steinberg, USAID Deputy Administrator, said at a seminar in Hanoi on Tuesday.
IPTD has been applied in the US, EU and Asia to successfully clean up toxic waste, he said.
He added that USAID awarded TerraTherm, Inc. a thermal remediation contract to clean up dioxin-contaminated soil and sediment at the Da Nang Airport. The work is expected to be completed in August 2012.
TerraTherm Inc. plans to excavate 72,900 cubic meters of contaminated soil and sediment at the airport--one of the most highly contaminated "hot spots" that was used for the storage and handling of Agent Orange during the Vietnam War.
The IPTD approach will involve the construction of an above-ground, covered and fully insulated structure to be filled with soil and then heated to destroy the dioxin.
Steinberg said the project will be conducted very carefully to ensure the safety of both the project workers and the local people.
