Interview with Prof. Kevin A. Schug
We interviewed with Dr. Kevin A. Schug, Associate Professor and Shimadzu Distinguished Professor of Analytical
Chemistry in the Department of Chemistry and Biochemistry at the University of Texas at Arlington (UT Arlington). His
research is mainly on the separation of bioactive chemical compounds with mass spectrometry techniques. Also, he is
currently undertaking one of the most extensive investigations of the potential impact of industrial processes, such as
unconventional drilling and hydraulic fracturing, on our environment. He and Shimadzu started collaborative work in
2012 when the Shimadzu Center for Advanced Analytical Chemistry was established.

have taken and analyzed over 800 well water samples in proximity

the largest effort to date of this kind. In 2011, we realized that very
little work had been done to assess potential environmental impacts
of this industrial activity, which has been so very important to the
United States economy. It has been our goal to be objective and
simply collect data that no one else was collecting. As an academic
entity, we could remain wholly unbiased, and in fact we have done
much of our work without outside support, beyond some funds
provided by the University, and the availability of a large suite of
analytical instruments based on the Shimadzu partnership. We have
developed a core set of analytical techniques based on Shimadzu
GC-MS, headspace GC-FID/BID, ICP-OES, and TOC/TN analyses.
These methods borrow best practices from standard methods, but
also build in a combination of targeted and untargeted strategies to
allow for a comprehensive evaluation of water quality. In an early
