The Q&A session for this topic is Q&A 1: Water for Cannabis, Emerging contaminants & PFAS Occurrence, Effects, and Treatment.
Some PFAS are both environmentally persistent, water soluble, and bio-accumulative. As a result, they can create extremely large groundwater plumes, posing a risk to both public and private drinking water supplies. Since 2003, the state of Minnesota has been investigating just such a groundwater plume, covering over 150 square miles that has contaminated over 4,000 private water supply wells (and public wells). This session will provide an overview of this unique class of chemicals, what we currently know about the health risks they pose, and how we can address them when found in drinking water.
