Dr. Alex Beebe is a hydrologist and environmental geologist and currently serves as a Professor of Geology in the Department of Earth Sciences at the University of South Alabama. He received a B.S. in Geology and Biology from the University of South Alabama in 2007 and went on to receive his Ph.D. in Environmental Engineering and Science from Clemson University in 2013. Dr. Beebe’s research interests are strongly focused on interactions between humans and the environment, particularly the relationship between human activities and the quantity and quality of precious water resources that we rely upon as a society.  Dr. Beebe’s previous research projects have included physical and chemical characterization of produced water generated during unconventional natural gas production, evaluation of petroleum bi-product water for beneficial use, design and implementation of constructed wetland treatment systems for beneficial reuse of industrial wastewater, and assessment of water treatment via ion exchange using natural geologic materials.

Since joining the Department of Earth Sciences in 2013, Dr. Beebe has expanded his research to investigate factors influencing water quality in Mobile and Baldwin Counties As a groundwater hydrologist, Dr. Beebe is currently working to elucidate the effects of diffuse groundwater discharge through seafloor sediments (i.e. submarine groundwater discharge) on the quality of waters in Mobile Bay and other Gulf of Mexico estuaries. This interdisciplinary research draws upon aspects of hydrology, hydrogeology, biogeochemistry, and oceanography to provide essential linkages between human activities and critical ecosystem services offered by our coastal waters.
