Compound Specific Isotope Analysis (CSIA)

2.0 PDHs 

Compound specific isotope analysis (CSIA) is an analytical method that measures the ratio of stable isotopes (13C/12C, 2H/1H, or 37Cl/35Cl) of a contaminant. CSIA results can provide conclusive proof of contaminant degradation, insight into degradation mechanisms, rate estimations, and contaminant source distinction/delineation.
Dr. Sam Rosalina and John Wilson have spoken at conferences all over the world about CSIA, and they’re world renowned for their work.  This EnviroClass will teach you how to use CSIA for your remediation projects to get results.

Dr. John T. Wilson has extensive experience in natural attenuation processes and bioremediation. He is currently the Principal Scientist with Scissortail Environmental Solutions, LLC. Dr. Wilson served as a research microbiologist for U.S. EPA at the R.S. Kerr Environmental Research Center in Ada, Oklahoma for 35 years. He has a B.S. in Biology from Baylor University, an M.A. in Microbiology from the University of California at Berkeley, and a PhD. in Microbiology from Cornell University.

Dr. Wilson’s research for EPA was primarily on natural attenuation of BTEX compounds, fuel additives, and chlorinated solvents, as well as in-situ bioremediation of chlorinated solvents. He has over 60 publications on these topics. He was a co-author and edited the U.S. EPA Report titled A Guide for Assessing Biodegradation and Source Identification of Organic Ground Water Contaminants using Compound Specific Isotope Analysis (CSIA). In addition to his research activities, he provided training and technical assistance to the EPA regions and to state agencies.
