Due to potential negative health consequences of per- and poly-fluorinated alkyl substances (PFAS), this group of chemicals are being considered by USEPA for drinking water regulations under the Safe Drinking Water Act (SDWA). Regulations are expected to be promulgated in short order. Since PFAS compounds are widely observed in municipal wastewaters and are often not completely removed through the traditional wastewater treatment processes, water reuse applications are inevitably faced with the presence of these contaminants in the recycled water stream. This presentation will provide information about the background and treatment of PFAS compounds as well as will discuss potential implications of various treatment schemes being considered for direct potable reuse – in Arizona and in other communities in the United States.
