Episode Four focuses on a material with promising potential in destroying, detecting, and sequestering PFAS. Jeff Speaks with Dr. Radha Kishan Motkuri of Pacific Northwest National Laboratory about PFAS Detection, Capture, and Destruction Using Nanoporous Materials. Dr. Motkuri and his colleagues have patented the groundbreaking Fast PFAS Sensor: a reusable, pocket-sized device that that can quickly and accurately detect PFAS, even at levels below the federal threshold.
