1,4-Dioxane Remedial Techniques Webinar

MichaelMarley-tnMichael 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
