Transient Simulation of 1, 4-Dioxane Fate and Transport During Enhanced Soil Vapor Extraction Treatment

1, 4-Dioxane is an emerging contaminant a that fully miscible in water and resistant to biodegradation. The presence of vadose zone creates prolonged environmental issues risk human health. To date, treatment technologies for remediation are still being developed. In this work, numeric simulation tool was developed investigate the fate transport enhanced soil vapor extraction (XSVE) which utilizes heated air injection improve removal efficacy. results suggested identify source critical XSVE treatment, inaccurate heat point would prolong duration.
