Per-and Polyfluorinated Alkyl Substances (PFAS) Cycling within Michigan: Contaminated Sites, Landfills and Wastewater Treatment Plants

Concentrations of PFAS from public and private sources in Michigan compiled for wastewater treatment plants) (influent, effluent, biosolids), contaminated sites, and landfill leachates reveal complex cycling within the natural and engineered environment. December 18, 2021 | Water Research

A New OECD Definition for Per- and Polyfluoroalkyl Substances

The report presents a revised, broadly inclusive PFAS definition: “PFASs are defined as fluorinated substances that contain at least one fully fluorinated methyl or methylene carbon atom (without any H/Cl/Br/I atom attached to it), i.e., with a few noted exceptions, any chemical with at least a perfluorinated methyl group (−CF3) or a perfluorinated methylene group…

Identification of point source dischargers of per- and polyfluoroalkyl substances in the United States

The report provides a screening-level analysis of the potential for environmental PFAS releases from contaminated sites, active industrial sites, wastewater treatment plants, and waste disposal sites (including active and inactive landfills) nationwide.

Concentration profiles of per- and polyfluoroalkyl substances in major sources to the environment

A review of published literature was conducted to present the concentrations and composition profiles of per- and polyfluoroalkyl substances (PFAS) from significant sources to the environment. The characteristic compounds and concentrations are summarized as found from direct sources such as manufacturing facilities, aqueous film-forming foam (AFFF) applications, metal coating operations, and textile and paper coating…

Membrane-based technologies for per- and poly-fluoroalkyl substances (PFASs) removal from water: Removal mechanisms, applications, challenges and perspectives

The study critically reviews and analyzes the current state-of-the-art of membrane-based techniques for PFASs removal, including direct membrane filtrations, adsorption-based membranes, and hybrid membrane processes. September 21, 2021 | Environment International
