Dr. Duane Graves is a principal scientist based in Tennessee with over 20 years of experience. His expertise includes: in environmental biotechnology; environmental forensics; in situ groundwater, soil, and sediment remediation; evaluation of airborne biological contaminants; and remediation of groundwater in karst formations.

Dr. Graves specializes in the development, selection, feasibility evaluation, design, and deployment of remedial solutions for: hazardous, radioactive, and mixed-waste; contaminated soil, sediment, and groundwater; odor and biological agents investigation and mitigation; environmental forensics; and environmental biotechnology. His project involvement includes the development of technical approaches, hazardous waste treatability studies, remedial investigations and feasibility studies (RI/FS), corrective measures studies (CMS), corrective action plans, remedial designs, and interpretation and reporting of data to regulatory agencies, clients, and the public.

His efforts to advance the state of the practice include the first successful in situ bioremediation project for petroleum hydrocarbons in New York, and the first agency-approved monitored natural attenuation projects in California and Florida for petroleum hydrocarbons and chlorinated solvents, respectively. His solutions to challenging environmental problems have included the use of wind-powered biovents for diesel remediation in sub-artic Alaska, solar powered biosparging of groundwater in Georgia, passive oil field waste pond remediation in Mexico, and sequential extraction of metals from soil and sediment to document metal attenuation processes in wetland and upland soils. In 2002, he co-developed and team-taught a short course on the “Natural Attenuation of Metals in Soil, Sediment, and Groundwater” at the Third International Conference on Chlorinated and Recalcitrant Compounds held in Monterey, California. In June 2005, Dr. Graves represented Geosyntec in a Cooperative Research and Development Agreement with the U.S. Geological Survey for commercialization of an innovative point-of-exposure bioremediation technology specifically designed for wetland environments, and a novel microbial consortium that degrades chlorinated ethenes, ethanes, and methanes.
