The technical approach for the project focused on the following tasks: (1) conduct a "big data" study to identify the typical scale and conditions within 1,4-dioxane and CVOC sites; (2) assess metal catalysis as a novel treatment approach; (3) evaluate chemical oxidation, catalysis, and biodegradation processes to understand the potential advantages of combined treatments on dioxane degradation kinetics; and (4) investigate the potential contribution of matrix diffusion processes on fate and transport via comprehensive modeling of typical dioxane release scenarios and a field investigation of the relationship between dioxane concentrations and site hydrostratigraphy at two contaminated groundwater sites. The goal is to use the findings to develop a more informed basis for managing 1,4-dioxane sites. https://www.estcp.com/content/download/45408/423960/file/ER-2307%20Final%20Report.pdf Project results are summarized in a lessons-learned fact sheet at https://www.estcp.com/content/download/41298/394372/file/ER-2307%20Lessons%20Learned%20%20Fact%20Sheet.pdf.
