Barbara Butler, Ph.D., U.S. EPA Office of Research and Development's Center for Environmental Solutions and Emergency Response (Butler.barbara@Epa.gov or 513-569-7468)
Dr. Barbara Butler is a Research Environmental Engineer in the Land Remediation Technology Division of the EPA's Office of Research and Development's Center for Environmental Solutions and Emergency Response. Barb's research focuses on understanding the fate, transport, and ecotoxicology of inorganics in surface water, groundwater and sediments in mining-influenced watersheds through field, laboratory, and modeling, and using that understanding for evaluation and design of remedial technologies, with a particular interest in passive treatment systems. She also provides technical assistance to multiple EPA Regions on both coal and hardrock mining issues, included reviewing proposed mitigation and treatment approaches and evaluating technology capabilities to determine suitability for implementation based on site-specific requirements. Barb obtained her Ph.D. and M.S. in Environmental Science & Engineering from the Colorado School of Mines and a B.S. in Chemistry from the University of Colorado.
