Per- and Polyfluoroalkyl Substances Investigation and Drinking Water Sampling and Reporting at Southern Vermont Regional Airport

In 2018, the Vermont Department of Environmental Conservation (VT DEC) and the Vermont Agency of Transportation (VTrans) evaluated the Southern Vermont Regional Airport (SVRA) in North Clarendon, Vermont for potential impacts related to the use of aqueous film-forming foam (AFFF) in firefighting apparatus during firefighting training and fire response activities. A phased sampling of bedrock groundwater monitoring wells revealed that groundwater in bedrock was impacted by common constituents of AFFF known as per- and polyfluoroalkyl substances (PFAS).
