Mr. Hardenstine is a biologist and has over 25 of experience in environmental chemistry. His background is in the detailed chemical analysis and interpretation of organic contaminants such as petroleum products and manufactured gas plant residues and wastes, and their characterization using advanced instrumental methods and sophisticated chemometric data interpretation techniques (forensic chemical fingerprinting. He has designed and implemented bench scale treatability studies in the areas of biodegradation and weathering of petroleum constituents, PCB congeners, and aroclors. He has managed the planning and technical work of over fifty projects involved with study of the fate and transport of organic contaminants in aquatic and terrestrial environments. Among those are the Valdez Oil Spill, Cosco Busan Oil Spill, and Deepwater Horizon. He holds a B.S. in Biology from Salem State College.
