Stable Isotope Analyses to Understand the Degradation of Organic Contaminants in Ground Water (Part 1)
Internet-based seminar
Hosted by U.S. EPA

When organic contaminants such as benzene, TCE or MTBE are degraded, the ratio of the stable isotopes of carbon in the organic contaminants will often change in a predictable fashion. In the last ten years, advances in analytical chemistry have made it possible to measure these changes, even when the organic contaminants are present in water at low concentrations. A determination of the ratio of the stable isotopes can reveal whether the contaminant has been degraded. If the mechanism of degradation is understood, and laboratory studies are ...  [click for more]
