Gradient will present in the “PFAS 360 Analytical Challenges and Risk Assessment Update” session at The 30th Annual International Conference on Soil, Water, Energy, and Air, March 16-19, 2020, at the DoubleTree Mission Valley, San Diego, California.
Over the last several years, significant media attention has been focused on the detection of PFAS in the environment and particularly in potable water supplies. Because of the public outcry regarding these compounds in the environment, regulatory agencies are compelled to issue orders or otherwise mandate the collection and analysis of environmental samples for an ever-growing list of PFAS. However, an EPA method is only available for drinking water, leaving commercial laboratories to their devices to develop their own methods, some very good and others not so much, resulting in extraordinary data comparability issues, not to mention serious issues with regulatory accreditation process.
While the technology (and reference materials) are available to measure up to 38 PFAS (and the list keeps growing), the scarcity of reliable toxicity studies for many PFAS has hampered the application of definitive risk assessments. Finally, as PFAS have been dubbed by the media as “Forever Compounds”, the persistent nature of PFAS has created interesting challenges for remediating environmental media.
PFAS 360 will be comprised of two 1-hour panel sessions, the first session addressing analytical challenges and the second session providing an update on risk assessments. Interactive discussion with attendee participation will follow.
