Vice President/Principal Scientist
Dr. Love leads Roux Associates’ Litigation Practice Group and provides forensic litigation support and expert witness services to clients throughout the United States on both environmental litigation and environmental insurance coverage related matters. Dr. Love’s experience includes strategic and technical analysis and guidance regarding numerous complex groundwater, soil, sediment, soil vapor and air contaminated sites. He has also provided expert technical guidance for state legislative actions and federal advisory panels on a range of traditional and non-traditional environmental hazards. Dr. Love’s expertise has been developed through a unique variety of University, Federal and post-academia work, including developing leading edge methods for addressing forensic questions related to weapons of mass destruction for the Federal Government. Dr. Love earned a B.A. in Geoscience from Franklin & Marshall College, a M.S. in Material Science and Mineral Engineering and a Ph.D. in Environmental Engineering – both from the University of California at Berkeley. Dr. Love performed post doctorate research at the Forensic Science Center of the Lawrence Livermore National Laboratory.
Outlook of Environmental Forensics in Distinguishing Sources of Perfluoroalkyl and Polyfluoroalkyl Substances
The C-F bonds in per- and polyfluoroalkyl substances (PFAS) are among the strongest in nature and bestow PFAS with unique chemical properties including high environmental mobility and resistance to degradation. Their unique chemistry combined with their toxicology, widespread environmental detection, investigation and cleanup-related challenges and increasingly stringent regulatory landscape position PFAS as the ultimate emerging contaminants. PFAS can enter the environment through diverse release pathways, including direct industrial point-sources, waste water treatment plant effluent, landfill leachate, former fire training areas and diffuse, non-point sources as well as through in-situ precursor compound degradation. Meanwhile, recent legal precedents, including a multi-million dollar settlement, establish a need for forensic investigation to distinguish the source, timing and contribution of PFAS releases to the environment. Environmental forensic techniques commonly used to investigate source, timing and contribution include fingerprinting, ratio comparison and knowledge of operational history. Here we provide insights into the potential application of these tools towards investigating PFAS sources.
