PFAS Observer
Per- and polyfluouroalykyl substances, or PFAS, are the subject of heightened scrutiny by federal and state governments as concerns rise about the tenacious chemicals’ impact on human health. PFAS are a group of several thousand synthetic chemical compounds resistant to heat, water, and oil that have become ubiquitous in modern life. The chemicals have been used since the 1940s to add water and stain repellency to fabric and carpet, to provide non-stick properties to food paper wrappings, and to make fire-fighting foams. They also are used in certain industrial operations, such as electroplating. While PFAS are useful for these and other purposes due to their hydrophobic and lipophobic properties, federal and state agencies have been scrutinizing the persistence of the chemical compounds, particularly in water sources.
