With expertise in situ biodegradation of chlorinated solvents in natural or engineered environments, Dave is a pioneer in the development, demonstration, and application of monitored natural attenuation (MNA) and enhanced in situ bioremediation (EISB) of these compounds. He aided researchers at the University of Waterloo developing the basis of zero-valent iron (ZVI) permeable reactive barriers (PRBs), led the first full-scale ZVI PRB installation in 1994, and commercialization of ZVI PRBs through establishing EnviroMetal Technologies. He worked with researchers at the University of Tennessee to commercialize the application of biomarkers (PLFA) and the establishment of Microbial Insights. He established SiREM (a division of Geosyntec) to commercialize intellectual property from DuPont and Stanford University (genetic markers for Dehalococcoides and dehalogenase enzymes) and University of Toronto’s (KB-1(TM) culture used to bioaugment sites for the in situ biodegradation of chlorinated solvents.Currently, he is managing the development of the STAR technology, a smoldering-based combustion technology to treat heavy hydrocarbons like creosotes and coal tars.
Dave has served on various national scientific and regulatory advisory boards including the U.S. EPA Expert Panel to address the benefits of partial source treatment of Dense Non-Aqueous Phase Liquids (DNAPLs); and on the U.S. National Research Council Committee on Geological and Geotechnical Engineering in the New Millennium. He was active on various workgroups for the Interstate Technology and Regulatory Council (ITRC), and developed and taught two ITRC courses to thousands of state and federal regulators. The ITRC has recognized his contribution to the ITRC through several awards. Dr. Major is also the author or co-author of over 50 peer-reviewed technical publications on environmental remediation topics, and over 45 conference publications, presentations, and posters. Dave was inducted into the Space Foundation/NASA Space Technology Hall of Fame: Products From Space Benefiting Planet Earth Award (2007), and has been awarded the University of Waterloo, Faculty of Science Alumni of Honour Award (2007), and the ASTM Hogentogler Award (2015).
