Biography

Charles D. Shackelford is Professor and Head of the Department of Civil and Environmental Engineering, Colorado State University, Fort Collins, Colorado, USA. He has 35 years of experience pertaining to the geoenvironmental aspects of waste management and environmental remediation, is a registered professional Civil Engineer in California and Colorado, and has served as an expert on waste disposal issues on numerous occasions for private companies and federal agencies. Dr. Shackelford’s research is focused primarily on evaluating flow and transport of hazardous liquids and contaminants through soil and geosynthetic containment barriers, such as compacted clay liners and geosynthetic clay liners, commonly used in geoenvironmental containment applications (e.g., landfills, surface impoundments, lagoons, secondary containment of above-grade fuel storage tanks, etc.), as well as through soil-bentonite vertical cutoff walls used for in situ control and containment of polluted groundwater. His most significant contributions have related to characterizing diffusion of potential contaminants through these barrier materials.
