Topic: Coal Ash Leachability: Technical and Policy Considerations

Presenter:  Dr. John Daniels, P.E., Chair, Dept. of Civil and Environmental Engineering, UNC Charlotte

Dr. Daniels currently serves as Professor and Chair of the Department of Civil and Environmental Engineering at UNC Charlotte. He also chairs the National Ash Management Advisory Board for Duke Energy.  While at UNC Charlotte, Dr. Daniels has led numerical, laboratory, and field-based projects for utilities and consultants, as well as state, national, and foreign agencies. Much of this work has focused on physical and chemical controls on soils and industrial byproducts, with a focus on coal fly ash. His laboratory participated in the validation testing as part of the approval process for the U.S. Environmental Protection Agency (EPA) Method 1314, one of the latest methodologies for evaluating the leaching potential of coal fly ash. His work with organo-silanes to render soil and ash hydrophobic has been recognized as a potential method for reducing infiltration and leachability, as cited in the U.S. EPA’s proposed rule on Coal Combustion Residuals.
