Abstract The extent of per- and polyfluoroalkyl substances (PFAS) in groundwater surrounding legacy landfills iscurrently poorly constrained. Seventeen PFAS were analysed in groundwater surrounding legacy landfillsin a major Australian urban re-development precinct. Sampling locations (n¼13) included sites installeddirectly in waste material and down-gradient from landfills, some of which exhibited evidence ofleachate contamination including elevated concentrations of ammonia-N (106 mg/L), bicarbonate(1,740 mg/L) and dissolved methane (10.4 mg/L). Between one and fourteen PFAS were detected at allsites and PFOS, PFHxS, PFOA and PFBS were detected in all samples. The sum of detected PFAS (P14PFAS)varied from 26 ng/L at an ambient background site to 5,200 ng/L near a potential industrial point-source.PFHxS had the highest median concentration (34 ng/L; range: 2.6e280 ng/L) followed by PFOS (26 ng/L;range: 1.3e4,800 ng/L), PFHxA (19 ng/L; range:
