ABSTRACT
As discussed in Chapter 3, 1,4-dioxane has a low Koc (soil adsorption coeffi cient for soil organic matter) and a high solubility and is therefore not highly sorbed to soils. Because of these characteristics, 1,4-dioxane is dominantly found in groundwater. Therefore, the following discussion of remedial technologies is focused solely on groundwater remediation methods, both ex situ and in situ, and does not address soil remediation methods. In this chapter, we fi rst describe each technology, and then we present literature studies to demonstrate the effectiveness of the technology at 1,4-dioxane removal or destruction. The literature studies include laboratory bench-scale studies and fi eld-scale tests, documenting the removal of 1,4-dioxane from groundwater or effl uent. Finally, we assess the technology’s likelihood of success in the remediation of actual sites contaminated with 1,4-dioxane.
