Andrew Garrabrants

Andy Garrabrants is an Associate Research Professor of Civil and Environmental Engineering at Vanderbilt University in Nashville, TN. where his research focuses on leaching tests and assessment approaches for estimating the fate and transport of constituents from soils, sediments and wastes.

 

His research focuses on continuing development and acceptance of standardized approaches toward environmental impact assessment of solid wastes, construction materials, soils, and sediments. He is the technical lead for the interlaboratory validation of the Leaching Environmental Assessment Framework (LEAF), developed in collaboration with the Energy Centre of the Netherlands, DHI Demark, and the Offices of Research and Development (ORD) and Solid Wastes (OSW) of the US Environmental Protection Agency.

 

Other research interests include (i) beneficial reuse of waste materials in construction, (ii) release assessment approaches for semi-volatile organics in soil/cement mixtures (e.g., in-situ stabilized soils), (iii), physiochemical models for estimating source terms for risk assessment and risk evaluation, and (iv) leaching chemistry and long-term durability of cement-based solidification/stabilization (S/S) waste treatment and cementitious engineered barriers for nuclear waste disposition.

 

Professor Garrabrants actively participates in the activities of ASTM International D-34 Committee on Waste Management serving as the Committee Vice Chair, Chair of the D34.03 Subcommittee on Recovery and Reuse, and leader of the D34.01.04 task group on Waste Leaching Techniques. He is currently serving on an expert panel convened by the Interstate Technology and Regulatory Council (ITRC) to write a technical regulatory guidance for on-site solidification/stabilization remediation of soils. He holds memberships in several professional societies including the American Institute of Chemical Engineers, American Society of Civil Engineers, and the American Chemical Society.
