ABSTRACT: Dr. Doug Cox will present on PFAS (perfluorinated alkyl substances), the latest “hot topic” in environmental circles. These chemicals are present in 99% of the US population due to their wide commercial and industrial use.  Most exposure to PFAS comes from contaminated drinking water sources and everyday products such as non-stick cookware, paper cups, food packaging, and clothing. Their use as a fire suppression agent has led to contaminated ground water and surface water near some military bases and airports. Concerns regarding their toxicity have generated extensive media coverage sparking the attention of regulatory agencies like EPA who are looking into ways to address this emerging contaminant. Dr. Cox will cover the latest scientific and regulatory findings regarding PFAS drawing from his experience on how these chemicals are being regulated elsewhere in the world.

Industries that will likely be affected by new regulations on PFAS include oil and gas, refineries, airports, military, electronics, and other manufacturing and processing operations.  An article on PFAS was recently included in the Denver Post ( Dr. Cox will discuss what these industries can do to prepare for the new PFAS regulations looming in the horizon.
