Michael Marley presented an informative webinar covering the both ex- and in situ remedial options for 1,4-dioxane on April 26, 2016.  1,4-Dioxane is a Contaminant of Emerging Concern (CEC) that is increasingly being detected in groundwater, surface water,and drinking water. 1,4-Dioxane is primarily associated with chlorinated solvent sites, where it was used as a stabilizer. The presentation outlined the properties of 1,4-dioxane as it impacts remedial technology selection. Case studies are used to illustrate both ex- and in situ remedial options for addressing 1,4-dioxane. The remedial options discussed included reliable, proven technologies such as advanced oxidation and sorption, but also address evolving technologies such as thermally enhanced removal, bioremediation, and phytoremediation.  A recording of the video is presented below.

Topic covered in the presentation are as follows:

• Basic properties of 1,4-dioxane with respect to remediation
• A discussion of applicable reliable remedial technologies with case studies
  • Ex situ
    • Advanced oxidation
    • Sorption
  • In situ
    • In situ chemical oxidation
• Promising remedial in situ technologies
  • Phytoremediation
  • Air Stripping
  • Thermally enhanced soil vapor extraction
  • Bioremediation
    • Analytical Methods to demonstrate destruction
