  • Vietnam: Environmental Remediation of Dioxin Contamination at Danang Airport

    Progress Report: March 1, 2014 to March 31, 2014

    USAID and the Government of Vietnam continued implementing the Environmental Remediation of Dioxin Contamination at Danang Airport Project launched in August 2012.

    CONSTRUCTION PROGRESS USAID contractors continued construction of the liquid and vapor treatment plant (LVTP) at the north end of the containment structure. Although 95% of the dioxin is destroyed in the containment structure, the LVTP is required to treat any trace level of dioxins as well as other contaminants of concern. The liquid and vapor that is collected and treated in the LVTP are analyzed for a number of compounds including dioxin to ensure that emission levels are safe. LVTP construction activities this month included: loading of the granular activated carbon (GAC) into the vessels; completing installation of the cooling tower; installation of the IPTD and LVTP supervisory control and data acquisition (SCADA) instrumentation; and construction of the main water supply line and emergency water supply reservoir.

    In preparation for Phase II excavation, the Vietnamese Ministry of National Defense (MND) conducted screening for unexploded ordnance (UXO) in Sen Lake and the surrounding wetlands. USAID contractors continued dewatering Sen Lake and the surrounding wetlands and began excavating contaminated soil and sediment from areas where UXO clearance and dewatering was completed.

    On March 18, 2014, USAID and MND hosted a Capacity Building Needs Assessment Workshop in Hanoi with the Government of Vietnams (GVN) top dioxin experts to identify key requirements for implementing dioxin remediation projects and to design activities to further develop GVN expertise in this area. On March 25, 2014, more than 80 representatives of the Danang government and community and local media attended a Community Outreach Session in Danang hosted by USAID and MND in cooperation with the Danang Peoples Committee (PC). Danang PC Vice Chairman Nguyen Ngoc Tuan opened the session followed by an update on the current status of the Project as well as upcoming activies by USAID and MND. A public service announcement about the start of the thermal treatment system, which will air on Danang TV starting April 15 for 15 days, was also previewed. In preparation of the remediation system start up, USAID coordinated discussions with key project stakeholders, including the Danang Department of Natural Resources and Environment, Office 33, Chemical Command and Army Division 372. The discussions focused on reviewing specifics of the LVTP operations, schedule, sampling procedures, emergency action plans and monitoring requirements.
