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