The data set is the raw data derived for the study by Kleja et al (2025). The set contains results for one field-contaminated soil and three spiked soils (12 PFAS contaminants) aged for 5 months, all of which were examined using batch tests in accordance with ISO 21268-2: 2019 with either deionised water or 1 mM CaCl2 as leachant (liquid-to-solid phase ratio (L/S) of 10) and percolation tests according to ISO 21268-3:2019 with 1 mM CaCl2 as leaching fluid. The solubility of PFAS as a function of tumbling time (1, 8, 24, 48, 96 and 240 hours) with 1 mM CaCl2 as leachant in the batch test (ISO 21268-2:2019) was also investigated. Leach-ate (eluate) produced using ISO 21268-3:2019 was analysed for PFAS, pH and conductivi-ty, while leachate from ISO 21268-2:2019 was also analysed for DOC, Al, Ca, Fe, K, Mg, Mn, Na, Cl and SO4.

Datasetet utgör rådata till studien av Kleja et al (2025). Setet innehåller resultat för en fältkontaminerad jord och tre spikade jordar (12 PFAS föroreningar) åldrade i 5 månader som alla undersöktes med batch test enligt ISO 21268-2:2019 med antingen avjonat vatten eller 1 mM CaCl2 som lakvätska (vätska-till-fast fas-förhållande (L/S) på 10) och perkolationstest enligt ISO 21268-3:2019 med 1 mM CaCl2 som lakvätska. Lösligheten hos PFAS som en funktion av skaktid (1, 8, 24, 48, 96 och 240 timmar) med 1 mM CaCl2 som lakvätska i batchtestet (ISO 21268-2:2019) undersöktes också. Lakvatten framtagna med ISO 21268-3:2019 analysera-des för pH och konduktivitet, medan lakvatten från ISO 21268-2:2019 också analyserades för DOC, Al, Ca, Fe, K, Mg, Mn, Na, Cl och SO4.
