The document outlines a 15-step process to remediate contaminated soil and sediment from Danang Airport. Step 1 involves sampling surrounding soils to ensure all contaminated material is excavated. In Steps 2-4, excavated soil is enclosed in an insulated cap. Steps 5-7 install liquid and vapor collection systems and begin heating to dry the soil. Steps 8-11 apply sustained heat to destroy dioxin structures. Steps 12-13 add water for cool down and collect steam and water. Step 14 conducts sampling to confirm clean soils. Steps 15 removes the insulated cap upon completion.
