Using a well-studied Superfund site, this presentation shows that 1,4-dioxane can be a driving contaminant for risk management and remediation decisions due to its physical/ chemical properties and toxicity. Specifically, 1,4-dioxane may be the predominant VOC at the groundwater plume's leading ...
Groundwaters from the Lowry Landfill Superfund Site, Aurora, CO, have been treated using a UV catalyzed hydrogen peroxide advanced oxidation process, which has had difficulty removing 1,4-dioxane to low levels due to UV absorbance by the waters. Parsons performed a bench study to investigate ...
Pilot studies conducted during the process development phase established a design basis process loading factor of 0.6 g 1,4‐dioxane and THF (as chemical oxygen demand [COD])/g total solids per day and proved the efficacy of the process. Full‐scale design includes the use of three parallel ...
