3 Overview

4 The Tenth International Conference on Remediation of Chlorinated and Recalcitrant Compounds will be conducted May 22–26, 2016, in Palm Springs, California. Like the previous conferences in this series, it is presented and organized by Battelle. Sponsors include other leading organizations active in site remediation research and application. Attendance is expected to be 1,500 to 1,700 scientists, engineers, regulators, and other environmental professionals representing universities, government site management and regulatory agencies, and R&D and manufacturing firms from around the world.

GSR has been around in some form or another since the early 2000s; however, industry standards are just starting to take form.

This technique should not be thought of as a standalone technique, but one that should be integrated with conventional techniques such as GC and GMS. In this course the basic concepts of stable isotopes will be introduced. This will be followed by discussion of applications to groundwater samples, free product samples, and soil samples as well as vapor intrusion applications. Integration of GC and GMS data will also be discussed. Applications will include utilization of stable isotopes of C, H, and Cl to both source discrimination studies and natural attenuation studies.
