National Estimate of Per- and Polyfluoroalkyl Substance (PFAS) Release to U.S. Municipal Landfill Leachate

Environmental Science & Technology, 51(4), 2197–2205.

By: J. Lang n, B. Allred*, J. Field *, J. Levis  n & M. Barlaz n 

MeSH headings : Environmental Monitoring; Refuse Disposal; Solid Waste; Waste Disposal Facilities; Wastewater; Water Pollutants, Chemical
TL;DR: The concentrations of 70 PFASs in 95 samples of leachate were measured in a survey of U.S. landfills of varying climates and waste ages and six PFAS demonstrated significant variation with climate. (via Semantic Scholar)
