PFAS förorening i grundvatten

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. At the site groundwater was previously used as a drinking water source consequently affecting the inhabitants. In Sweden there are many areas with similar issues. The variation in PFAS concentrations corresponding to an annual emission estimate was studied at two groundwater wells. Factors influencing the estimate as well as how it affects the assessment of a contaminated area were analysed. The emission source and rates were firstly studied followed... (More)
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. At the site groundwater was previously used as a drinking water source consequently affecting the inhabitants. In Sweden there are many areas with similar issues. The variation in PFAS concentrations corresponding to an annual emission estimate was studied at two groundwater wells. Factors influencing the estimate as well as how it affects the assessment of a contaminated area were analysed. The emission source and rates were firstly studied followed by an estimate of the transport in soil and groundwater. Three PFAS (PFOS, PFHxS, and FASA) were selected as possible substances in AFFF with a yearly total emission of 280±220 moles. Of the emission source 67% of the total amount partitioned into soil and 33% to the groundwater, thus the majority was retained in the soil. The estimated concentration in two of the drinking water wells were a total of 600,000±450,000 ng/L and 490,000±370,000 ng/L, with 66% consisting of FASA, 20% of PFHxS, and 14% of PFOS. In addition, the removal of water from the drinking water wells showed a reduction in the groundwater concentration by 17%. (Less)
Abstract (Swedish)
Brandskum som innehåller per- och polyfluorerade ämnen (PFAS), på engelska Aqueuous Film Forming Foam (AFFF), är en av de främsta källorna till föroreningarna i Sverige. Grundvattenförorening orsakat av användandet av AFFF under brandövningar har undersökts i Kallinge, Blekinge. I området har grundvattnet använts som råvatten vilket resulterat i förhöjda halter av PFAS i dricksvattnet. Liknande fall har också rapporterats från andra områden i Sverige. Variationen i PFAS-koncentration som motsvarar ett årligt utsläpp uppskattades vid två grundvattenbrunnar som tidigare användes för dricksvattenförsörjning. Faktorer som påverkar den uppskattade koncentrationen och hur dessa faktorer påverkar bedömningen av ett förorenat område undersökts och... (More)
Brandskum som innehåller per- och polyfluorerade ämnen (PFAS), på engelska Aqueuous Film Forming Foam (AFFF), är en av de främsta källorna till föroreningarna i Sverige. Grundvattenförorening orsakat av användandet av AFFF under brandövningar har undersökts i Kallinge, Blekinge. I området har grundvattnet använts som råvatten vilket resulterat i förhöjda halter av PFAS i dricksvattnet. Liknande fall har också rapporterats från andra områden i Sverige. Variationen i PFAS-koncentration som motsvarar ett årligt utsläpp uppskattades vid två grundvattenbrunnar som tidigare användes för dricksvattenförsörjning. Faktorer som påverkar den uppskattade koncentrationen och hur dessa faktorer påverkar bedömningen av ett förorenat område undersökts och modellerats. Först undersöktes sammansättningen och mängden PFAS, följt av transport i mark och grundvatten. Tre PFAS (PFOS, PFHxS, och FASA) valdes som möjliga ämnen i AFFF, med en årlig utsläppsmängd på 280±220 mol. Av dessa fördelades 67 % i marken och 33 % i grundvattnet. Koncentrationen vid grundvattenbrunnarna var totalt 600 000±450 000 ng/L och 490 000±370 000 ng/L där 66 % utgjordes av FASA, 20 % av PFHxS och 14 % av PFOS. Effekten av vattenuttaget från brunnarna uppskattades minska koncentrationen i grundvattnet med 17 %. (Less)
