  1. 1. Modeling PFAS Transport in Groundwater - Exploring current approaches and evaluating parameter importance

    University essay from Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Teknisk geologi

    Author : Clara Eklund; [2023]
    Keywords : PFAS; Groundwater modeling; FEFLOW; Python; Machine learning; Technology and Engineering;

    Abstract : PFAS contamination in drinking water is a current problem, and new regulations for drinking water limits were recently implemented in each member country of the EU in January this year. Understanding the spread of PFAS in groundwater is therefore important to prevent it from reaching drinking water sources. READ MORE

  3. 2. 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

  4. 3. 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.

  5. 4. 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

  6. 5. Removal efficiency of perfluoroalkyl substances (PFASs) in drinking water : evaluation of granular activated carbon (GAC) and anion exchange (AE) using column tests, and the effect of dissolved organic carbon

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Anna Östlund; [2015]
    Keywords : PFASs; perfluoroalkyl substances; removal efficiency; granular activated carbon; GAC; anion exchange; AE; dissolved organic carbon; DOC;

    Abstract : Poly- and perfluoroalkyl substances (PFASs) are a group of environmental contaminants that have gained increasing attention due to their potential to bioaccumulate, environmental persistence and potential toxicity. PFASs have been found in surface water, sediment, air, soil, sludge and ice caps globally, as well as in wildlife and humans. READ MORE
