A relatively unexplored source of pollution is fire stations and their usage of aqueous film forming foam (AFFF) containing per- and polyfluorinated substances (PFAS). It is well documented that these were used at fire drill sites that contaminated surrounding surface water, sediments and groundwater. The aim of this study was to assess whether fire stations could be a source of pollution and spread of PFAS and if the industry should be given priority for further investigations. Four fire stations were selected for the assessment, which were carried out by using part one of the Method of Surveying Contaminated Sites (Acronym in Swedish: MIFO). This included studies of maps, archives and field visits where fire fighters were interviewed to gather information about activities that had taken place historically on the specific sites. All of the fire stations were classified as level 2, meaning they pose a high risk for the enviroment and human health accordning to MIFO. In conjunction to the assessment, existing testing results of PFAS in soil and water from other fire stations in Sweden are submitted in purpose of showing the general situation of pollution linked with the results of this evaluation. The conclusion of this study was that various activities at fire stations possibly have polluted ground -and surface waters and that the industry should be given priority for further investigations.
