OVERVIEW

Stable Isotope including Specific Isotope Analysis (CSIA) are one of the most growing tools applied in contaminant studies. This short course is designed to present the latest advancement in CSIA and the potential applications of CSIA in better understanding contaminated sites. CSIA have been successfully used in determining the source of contaminations, understanding the fate of contaminants in the groundwater, and evaluating the effectiveness remediation actions including the performance assessment for a broad range of biological (natural and enhanced), chemical (e.g. In-Situ Chemical Oxidation (ISCO) and Permeable Reactive Barriers (PRB) and physical (e.g. thermal treatment and Pump and treat) remediation strategies. In the last decade, CSIA have been extensively applied to many contaminated sites and the outcome proved to be highly successful. Most previous studies heavily relied on 13C-CSIA, however, recent investigations have been employing additional isotopes (37Cl-CSIA and 2H-CSIA). The recent interest in the two dimensional isotope approach (13C and 37Cl) or in some cases three dimensional isotope approach (13C, 37Cl and 2H) is driven by the advancements in the analytical methodologies, laboratory evidences, and also field applications that demonstrated the added value of the application of multiple – CSIA in contaminant studies. The course will include a short introduction the background of CSIA followed by an extended presentation of several field case studies, with a special focus on the latest advancements in the use of multi-CSIA (13C-CSIA, 37Cl-CSIA, and 2H-CSIA).

The agenda of the short course will cover the following:

  1. Basic concepts of environmental isotopes and CSIA including analytical techniques
  2. Collection, Preservation, and Storage of Samples – laboratory issues and quality control.
  3. CSIA application for source apportionment: case studies.
  4. CSIA for natural attenuation evaluation: case studies.
