PERFORMANCE EVALUATION OF USAID'S ENVIRONMENTAL REMEDIATION AT DANANG AIRPORT
U.S. Agency for International Development (USAID), Office of Economic Growth, Education and Environment (E3), Office of Economic Policy, 110 pp, 2018

Remediation of the Danang Airport was a 10-year, $103.5 million project that aimed to characterize, remove and contain dioxin-contaminated soil and sediment from site hot spots. Originally, 73,000 m3 contaminated soils and sediments were scheduled to be excavated from the airport into a secure landfill. Based on a 2010 environmental assessment, the project expanded to include in-pile thermal desorption to heat dioxin-contaminated soil to 335°C, causing dioxin to break down into non-toxic components. The project excavated 162,567 m3, treated 94,593 m3 and contained 67,974 m3 of contaminated soil in landfills. It was cost-effective, treating large amounts of dioxin and contaminated materials at a low per-unit cost and in a short time. https://pdf.usaid.gov/pdf_docs/PA00TDS3.pdf See video for more information: https://www.usaid.gov/news-information/videos/pile-thermal-desorption-iptd-animation See presentation for more information: https://www.aspeninstitute.org/content/uploads/2017/09/4-Kent_Sorenson-et-al-Dioxin-2017.pptx
