  1. 1. Selected PFAS in the water treatment at the waste-to-energy plant in Umeå : Investigating concentration and composition of selected PFAS in different water treatment steps

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Amanda Carlund; [2023]
    Keywords : ;

    Abstract : The present study investigated the changes in concentration and composition of five selected PFAS substances in the water treatment at the waste-to-energy plant in Umeå. The five PFAS were PFHxA, PFHpA, PFOA, PFHxS and PFOS. As PFAS exists in a variety of consumer products, they will to some extent end up in waste incineration. READ MORE

  3. 2. Is two stage GAC better than one stage GAC for removing PFAS at a DWTP? : Investigation of PFAS removal from drinking water using two stage granular activated carbon (GAC) filter

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Oliver Ekesiöö; [2023]
    Keywords : GAC; PFAS; drinking water treatment; two stage GAC;

    Abstract : The removal of 34 per- and polyfluoroalkyl substances (PFAS) were compared in a 1 stagegranular activated carbon (GAC) filtration to a 2 stage GAC filtration in a pilot study at adrinking water treatment plant (DWTP). The PFASs that were present in the water wereperfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), perfluoropentanoic acid(PFPeA), perfluorohexanoic acid (PFHxA), perfluoroheptanoic acid (PFHpA), perfluorobutanesulfonic acid (PFBS), perfluoropentane sulfonic acid (PFPeS) and perfluorohexane sulfonic acid(PFHxS).

  4. 3. 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

  5. 4. Human Exposure to Per- and Polyfluoroalkyl : Substances through Fish Consumption

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Welmoed Nauta; [2023]
    Keywords : Per- and polyfluoroalkyl substances; Human exposure; Fish consumption; Glasbruket; Target analysis; Mass balance analysis;

    Abstract : Human exposure to per- and poly-fluoroalkyl substances (PFAS) occurs mainly through two pathways, inhalation and ingestion. Dietary exposure to persistent organic pollutants (POPs), including PFAS, is driven mainly by the consumption of foods of marine or terrestrial animal origin. READ MORE

  6. 5. Hydrodynamic Modelling of Spread of Perfluoroalkyl Octanoic Sulphonate and Perfluoroalkyl Hexanoic Sulphonate in Lake Ekoln

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Prajwol Prajapati; [2022]
    Keywords : Hydrodynamic modelling; water quality; PFAS; PFOS; PFHxS; MIKE 3 FM; Ekoln; Fyrisån;

    Abstract : Per and polyfluoroalkyl substances (PFAS) are found ubiquitously in the environment across the globe.These substances have high persistence due to the strong carbon and fluorine bond. In the aquaticenvironment, due to high persistence, these substances don’t decay easily and are detected on the surfaceas well as in groundwater sources. READ MORE
