SERDP Project ER-2535, 53 pp, 2017

The project objective was to develop a reliable method to perform compound-specific isotope analysis (CSIA) on low aqueous concentrations (1 µg/L) of 1,4-dioxane in groundwater and then apply it to investigate 1,4-dioxane biodegradation. Researchers determined that 0.5 grams of a synthetic carbonaceous sorbent, when added to a 40 mL vial containing aqueous 1,4-dioxane in the 10 to 100 µg/L range, could adsorb > 99% of the 1,4-dioxane from solution. The 1,4-dioxane was recovered from the dried solid sorbent by thermal desorption into a gas chromatograph with isotope ratio mass spectrometry. The method was applied successfully to samples at concentrations in the 1 µg/L range. It is anticipated that the CSIA method will be applied to demonstrate the biodegradation of 1,4-dioxane in the 1-100 µg/L range. https://www.serdp-estcp.org/content/download/47014/440610/file/ER-2535%20Final%20Report.pdf
