Jeff Hardenstine

Mr. Hardenstine has over 25 years of experience in the generation and interpretation of chemical data for various forms of organic contaminant.  Much of his work has focused on the molecular-level characterization of crude oil, refined petroleum products, and PCBs. He has designed and conducted benchtop and field weathering studies to assess rates and effects of physical and biological weathering on chemical fingerprints and contaminant mass.  

Mr. Hardenstine has a strong background in environmental laboratory methods.  He is fully trained in standard U.S. Environmental Protection Agency (EPA) chemical analytical methods but has also led efforts in tailoring standard methods for forensic applications.  He is particularly experienced in sample extraction and clean-up techniques, especially in complex matrices (e.g., biological tissues) and regularly provides training, audits, and technical oversight to commercial and client laboratories in the US and overseas. He has designed and implemented novel laboratory studies of general relevance (e.g., analytical holding time studies for volatile and semi-volatile compounds) and project-specific relevance (e.g., bench scale weathering and treatability studies of petroleum under site-specific conditions).  Most recently he has designed and conducted a study of, PCB congeners and Aroclors in sediments and paint chips.
