MASS FLOW AND FATE OF PER- AND POLYFLUOROALKYL SUBSTANCES IN A LANDFILL IN UPPSALA, SWEDEN
Bonnet, Bjoern Frederik, Master's thesis, Swedish University of Agricultural Sciences, Upsala. 68 pp, 2017

In a study of PFAS translocation from a landfill via drainage into nearby water systems, distribution and fate of 28 PFASs were analyzed in drainage water, sewage sludge, and groundwater all across the landfill area and in the receiving water courses. The total mass flow of PFASs exiting the landfill was estimated at 220 mg/g. The mass flow in the river showed no long-range effect (30 km) of the landfill PFASs on surface waters; instead, PFASs from the landfill appeared to present a greater threat to the local groundwater. The study included assessment of an on-site drainage water treatment system in terms of PFAS removal efficiency. The treatment system showed efficiencies of around 50% for the simple treatment techniques applied (i.e., aeration, moving bed biofilm reactor, sedimentation pond, polishing ponds/lakes, and oxidation pond). https://stud.epsilon.slu.se/13052/
