Extending the Applicability of Compound-Specific Isotope Analysis to Low Concentrations of 1,4-Dioxane Phase 2

Abstract

The objectives of this project are: to improve estimates of the long-term impact of natural attenuation processes on groundwater contaminants. Specific objectives of this research areto:1. Develop a reliable method for performing CSIA on low levels of 1,4-dioxane in groundwater(e.g. 1 to 10 micrograms per liter; g/L);2. Assess the fractionation of stable carbon and hydrogen isotope ratios during the aerobic co-metabolic biodegradation of 1,4-dioxane under laboratory and field conditions; and3. Assess the use of stable carbon and hydrogen isotope ratios as tools to evaluate biodegradation of 1,4-dioxane at United States Department of Defense (DoD) sites with different groundwater conditions.
