1. 1. PFAS Contamination in Groundwater; Evaluating Factors Influencing the Impact of PFAS Contamination on the Drinking Water Source in a Holistic Approach _________________________

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Anna Söderman; [2023]
   Keywords : PFAS; Contamination; Firefighting Foam; Groundwater; Drinking Water; Technology and Engineering;

   Abstract : Aqueuous Film Forming Foam (AFFF) containing Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) is one of the major sources of groundwater contamination in Sweden. Groundwater contamination caused by the use of AFFF in correlation to fire training events was investigated in Kallinge, Sweden. READ MORE

3. 2. Evaluation of Dissolved Air Flotation for Water Purification: With Focus on Floc Characteristics and PFAS

   University essay from KTH/Kemiteknik

   Author : Ludwig Löf; [2021]
   Keywords : Water treatment; Sedimentation; Flotation; PFAS; Zeta potential; Vattenbehandling; Sedimentering; Flotation; PFAS; Zeta potential;

   Abstract : I detta projekt har experiment utförts med mål att förse kommunalförbundet Norrvatten med data som kan användas som underlag för beslutsfattande angående om deras fällningslinjer i vattenreningsprocessen ska köras i flotation eller sedimentering. För detta ändamål har koncentrationen av poly- och perfluorerade alkylsubstanser (PFAS) samt karaktär av agglomererade partiklar (flockar) undersökts och jämförts mellan fällningslinjer som körs i olika konfigurationer.

4. 3. Per- and Polyfluoroalkyl Substances (PFASs) Removal from Landfill Leachate : Efficiency Evaluation in Column Experiments

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Emelie Johnson; [2019]
   Keywords : ;

   Abstract : Per- and polyfluoroalkyl substances (PFASs) are known for their wide spread in the environment, their persistent properties and their ability of biomagnification through the food chain. With properties such as oil and water repellence, temperature resistance and a long lifespan they have been frequently used in various areas, e.g. READ MORE

6. 5. The research on perfluoroalkyl and polyfluoroalkyl substances (PFASs) in different research areas from the 1950s to the present.

   University essay from Lunds universitet/Miljövetenskaplig utbildning

   Author : Amanda Sahlin; [2017]
   Keywords : högflourerade ämnen; PFCs; perfluorinated chemicals; PFASs; Perfluoroalkyl and polyfluoroalkyl substances; poly - och perfluorerade alkylsubstanser; PFAS; Earth and Environmental Sciences;

   Abstract : Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are found globally in the environment, in humans and in wildlife and it is still not sure how these substances affect humans and animals. This study was performed as a systematic review to examine when these substances first attracted attention in different research areas. READ MORE
