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

1,4-dioxane

Peter Bennett, Principal Consultant at Haley & Aldrich, is the lead author of a newly published report, “Extending the Applicability of Compound-Specific Isotope Analysis to Low Concentrations of 1,4-Dioxane – Phase 2.” Bennett and Dr. Ramon Aravena of the University of Waterloo produced the report as part of a project for the Department of Defense Strategic Environmental Research and Development Program (SERDP).

The project allows for the use of an advanced tool, compound-specific isotope analysis (CSIA), to assess 1,4-dioxane degradation in groundwater. CSIA is a powerful a tool to verify degradation of common groundwater pollutants, but prior to this project, CSIA was not sensitive enough for application at many sites with 1,4-dioxane contamination. This project enhanced the sensitivity of CSIA for widespread use at 1,4-dioxane sites. The new method involves pre-concentration of 1,4-dioxane onto a sorbent and is now commercially available at the University of Waterloo Environmental Isotope Laboratory.

This method can provide regulators with convincing evidence of 1,4-dioxane degradation at industrial-release sites and can inform appropriate remedial strategies.
