Last week, a letter was sent out to Livingston residents, explaining that at least one township well is above the limit of a recently-regulated contaminant. While that letter provided useful information, it also encouraged residents to do their own research on whether or not to drink the water.
This contaminant, PFOA (perfluorooctanoic acid), falls under a broader category of PFAS (polyfluoroalkyl substances) and is a synthetic chemical found in everyday household products, as well as in things like firefighting foam.
PFAS is used to make products stain, grease, heat and water resistant, and its sturdy structure means it takes much longer to break down in comparison to organic chemicals. More specifically, PFOA are used for its emulsifier and surfactant properties, or as fluoropolymers (such as Teflon), firefighting foams, cleaners, cosmetics, greases and lubricants, paints, polishes, adhesives and photographic films.
