Audio for "PFAS & Biosolids: Sources, Occurrence, Transport, and Treatment," Feb 26, 2026

This ITRC training will provide information on the current understanding of PFAS and biosolids, focusing on land application. It builds on the earlier topics covered in the PFAS 101 training. This training will provide information on potential sources of PFAS in biosolids, the implications of PFAS associated with land-applied biosolids, including leaching and associated risks, and a conceptual site model. It will also cover the nature and extent of PFAS, field and laboratory considerations when assessing land application sites, factors controlling PFAS mobility, PFAS treatment options for biosolids, and PFAS uptake by plants and animals in these settings, along with approaches to modeling that uptake. Resources and further details for the topics included in this training are available in the ITRC PFAS-1 guidance document, specifically in Sections 1.7, 2, 4, 5, 8, 10, 12, and 17.3, as well as in the Regulatory Programs Table. Key topics will include: Understanding the Sources and Types of PFASConsiderations for Evaluating Nature & Extent of PFAS Contamination at Land Application Sites Evaluating Fate and Transport of PFAS in the Environment from Land-Applied BiosolidsEvaluating and Modeling Risk from PFAS in Agricultural Settings Evaluating Treatment and Management Options for PFAS in Biosolids To view this archive online or download the slides associated with this seminar, please visit http://www.clu-in.org/conf/itrc/PFAS-landapp_022626/
