Bench Scale Thermal Treatment of 1,4-Dioxane

1,4-Dioxane (not to be confused with dioxin…although we also can certainly thermally treat that! See our updates from the Danang Vietnam project) is an industrial chemical widely used as a chemical stabilizer for chlorinated solvents. It is of environmental concern due to its classification as a probable human carcinogen coupled with its unique chemical properties such as high water solubility (and therefore high subsurface mobility in groundwater), low octanol-water partition coefficient (log Kow), and relative resistance to biodegradation [1]. Due to these properties, 1,4-dioxane is often present on the leading edge of a contaminant plume in groundwater and presents unique … Continue reading

The High Value of Thermal Treatability Studies

Laboratory treatability studies are often one of the first logical steps when considering In Situ Thermal Remediation (ISTR) at a given site. In relation to the full-scale source remediation, treatability studies can be a wise and relatively low cost investment in a proof of concept. You might begin with a lab study if you have a unique mix of target compounds in the treatment area, or a challenging geological matrix. Or perhaps certain stakeholders need some extra “convincing” that ISTR will work at your site.  A study performed on actual site materials can quantitatively demonstrate the effectiveness of various thermal … Continue reading
