There is evidence that exposure to PFAS can lead to adverse human health effects. PFAS have been manufactured and used in a variety of industries around the globe, including in the United States since the 1940s and their chemistry creates unique challenges in water treatment and remediation. The fate, transport, and chemical transformations of most PFAS in the environment are still unknown and are areas of active scientific research.We will explore the topics of PFOS, PFAS, PFOA, and emerging contaminants related to soil and groundwater remediation.  Over the past few years, several agencies and organizations have released strategies and recommendations related to emerging contaminants.  In general, emerging contaminants are ones for which incomplete toxicity data exists or for which new data has been released.  Emerging contaminants could also be from a new source or have a newly recognized exposure pathway or lower detection limit. This workshop will keep you up-to-date on the topic of emerging contaminants and will give you an understanding of how U.S. agencies such as EPA and DOE are working to develop approaches for dealing with emerging contaminants.  We will also discuss the chemical and physical properties of emerging contaminants, how these compare to more traditional contaminants, and how these impact the ultimate fate and transport of these chemicals.
