Tre kommuners arbete med PFAS i dricksvatten : En kvalitativ intervjustudie om svårigheter och möjligheter

Sammanfattning: Today there are many uncertainties in the form of a lack of knowledge about perfluorinated and polyfluorinated substances (PFAS) regarding long-term risks to health and the environment, there is no efficacy data for many environments. The fluorocarbon bond is the strongest chemical bond, which means that PFAS can be transported long distances, for example through water streams and into the atmosphere. If surface water and groundwater are contaminated by PFAS, people are at risk of exposure to PFAS through the drinking water. It is therefore important to investigate and identify what difficulties and opportunities the municipalities see in their work to influence and reduce the occurrence of PFAS in drinking water with PFAS in water revenues and drinking water. The purpose of the study is to map what Halmstad, Linköping and Uppsala municipality see for difficulties and opportunities in their work on influencing and reducing the occurrence of PFAS in drinking water and how the result relates to scientific research about national environmental management. We have chosen to do a qualitative interview with an analysis of the interview using previous research on national environmental management about actions, cooperation and policy, directives, guidelines, and legislation. Some of the conclusions the study came to where that the municipalities see similar difficulties and opportunities in working with PFAS and have similar ways of working with PFAS. But there are still some differences and similarities in what they see for difficulties and opportunities in their work with PFAS. Difficulties that have been identified are inadequate or unclear guidelines, directives, legislation and insufficient limit values. It is also a difficulty that the municipalities do not know where all sources of PFAS pollution come from. Opportunities that have been identified are collaborations, knowing where certain parts of PFAS's pollution come from. One possibility that exists is to influence certain polluting activities by means of distribution routes, to submit activities to improve purification methods and to set requirements for sampling and remediation.
