EPA Gets Serious on PFAS, Plans to Remove De Minimis Exemption

Alston & Bird’s Jeffrey Dintzer and Gregory Berlin look at EPA’s recent Toxics Release Inventory (TRI) report and note that EPA is apparently suspicious of what it has characterized as a “seemingly limited scope of PFAS reporting.” EPA plans to remove the de minimis exemption for PFAS, which is not a surprise given its increased…

Critical Review of Thermal Decomposition of Per- and Polyfluoroalkyl Substances: Mechanisms and Implications for Thermal Treatment Processes

This study critically evaluates the thermal decomposition mechanisms, pathways, and byproducts of PFASs that are crucial to the design and operation of thermal treatment processes. May 2, 2022 | Environmental Science & Technology

Fate of Per-and Polyfluoroalkyl Substances from Durable Water-Repellent Clothing during Use

Aging and washing of fabrics with durable water-repellant coatings made with PFAS release PFAS to the environment, while tumble drying does not affect the PFAS concentrations in textiles. April 19, 2022 | Environmental Science & Technology

Exploring the origin of efficient adsorption of poly- and perfluoroalkyl substances in household point-of-use water purifiers: Deep insights from a joint experimental and computational study

Investigations show that the household point-of-use (POU) water purifiers constituted with coconut shell activated carbon can achieve 21%-99% removal for 14 legacy and emerging PFAS in tap water based on the ratio of influent and effluent. April 11, 2022 | ScienceDirect
