The Hydrogeology Lab is part of the Oklahoma Geological Survey and the Mewbourne College of Earth and Energy at The University of Oklahoma(OU). Projects originating from the lab will examine water resources and groundwater related concerns in the state of Oklahoma and beyond.

Kyle E. Murray, Ph.D.

I joined the Oklahoma Geological Survey (OGS) as the OGS' Hydrogeologist in November 2011. As I establish my research program at OU, I will continue previous lines of research and establish new projects that are relevant to Oklahoma. Thus far I have explored the Central Oklahoma aquifer system which has high levels of naturally occurring arsenic and chromium. I have also examined the Arbuckle-Simpson Groundwater Basin and proposed an OGS-led project that will assist decision-makers, industry, and the public with long-term management of this important groundwater resource. In response to other public inquiries, I have prepared independent, scientific views of water quantity and quality issues in many other parts of Oklahoma.

Most of my research examines water quantity or water quality at the watershed-scale and takes advantage of Geographic Information Systems (GIS) to synthesize geologic, hydrologic, climatic, and ecologic data. Because there is a great urgency to sustainably manage our natural resources, my research has also examined renewable and unconventional energy resources and the interplay between energy, water, and global change.

I have enjoyed multi-disciplinary, multi-institutional, and international research collaborations with colleagues from Trinity University, Texas A&M University, Denver Museum of Nature and Science, Colorado School of Mines, Universidad de Almería, and others. Some of these were part of research grants and contracts from local, state and federal sources. Local and site-scale projects were supported by San Antonio Water System, City of San Antonio, Bexar Met Water District, City of Kenedy, and others. Regional-scale projects were supported by Colorado Department of Transporation, Water Environment Research Foundation, U.S. Department of Energy, and U.S. Geological Survey.

See my CV, for a more detailed description of my background and experience. I welcome contact from new collaborators or potential students with an interest in developing water-related projects.
