Greg Brodie is an environmental geologist with 34 years of industrial and university teaching experience related to electric power production, coal and uranium mining, and disturbed land and water environmental control technologies. He has been adjunct faculty in the departments of geology at University of Tennessee-Chattanooga since 1981. Before retiring and forming his own LLC, Gabbro Environmental Consulting, Inc. in 2012, he maintained progressive positions as Geologist, Environmental Scientist, Project Manager, Program Manager, and ultimately Senior Manager of Environmental Research at the Tennessee Valley Authority in Chattanooga, TN. During his TVA career, he conducted brief stints as an independent consultant for constructed water treatment wetlands. His expertise and experience include: Innovative water and wastewater treatment with passive technologies, such as constructed wetlands; Water quality and watershed conditions analysis and interpretation; Solid waste management and reuse; Biofouling control; Environmental impact review and compliance; Coal, uranium, and other mining and processing operations impacts analyses and remediation; and acid drainage remediation. Example projects for which he managed or conducted include: Removal and fate of ammonia and heavy metals in passive treatment systems; Passive treatment system cost-benefit evaluation; Evaluation of zero liquid discharge at fossil power plants; Multi-benefit water treatment and management; Water quality implications of wet to dry storage of coal combustion products; Research and demonstration of passive water treatment; Ash pond closure optimization; Terrestrial carbon sequestration integrated with electric power plant operations and by-product use.

Greg develops courses and teaches or has taught Structural Geology, Field Geology, and Environmental Geology, Geology of the National Parks, Senior Seminars, and other lower and upper level university geology courses. He was named UTC Adjunct of the Year in 2014. Greg is a council member of the Gerson Lehrman Group, an American expert network that operates a membership-based platform that provides independent ad-hoc consulting services to business professionals around the world. He performs independent consulting work related to coal mine drainage and reclamation, especially in Tennessee-Alabama coal fields.

 

Research Interests

Greg’s research interests include passive treatment technologies for industrial and mining wastewater treatment design, evaluation, maintenance, and operation optimization; Terrestrial and innovative carbon sequestration; Innovative mine reclamation and water management; Environmental geology of the Chattanooga region
