Course Description:

This course will appeal to LSPs and other environmental professionals as it will cover environmental forensics as applied to the investigation of sites impacted by per- and polyfluoroalkyl substances (PFAS)—a group of thousands of anthropogenically produced, fluorine-containing organic compounds. Because analytical techniques can now detect some PFAS at low parts per trillion in groundwater, and they have had ubiquitous commercial and industrial use as far back as the 1950s, the number of sites impacted by these environmental pollutants are growing, and at a rapid pace. In short, environmental professionals face many challenges to understanding the source, nature, and extent of PFAS contamination at a site, especially if there may be multiple sources or comingled plumes. 

Many of the forensics tools and techniques that can be applied to PFAS build upon those developed for other complex classes of contaminants, including petroleum hydrocarbons, PCBS, and dioxins. In addition, PFAS have some unique properties that need to be considered in a forensics investigation, from sampling and analysis to data analysis and visualization. In presenting a variety of PFAS forensics tools and techniques, the goal of the webinar is to help practitioners reach defensible conclusions, while avoiding overinterpretation of the data.
