This training class builds on the earlier information for introductory PFAS topics presented in the PFAS 101 CLU-IN training. The ITRC PFAS Beyond the Basics class provides more information related to potential sources of PFAS in biosolids, implications of PFAS associated with land-applied biosolids, vadose zone fate and transport processes that likely govern biosolids releases, treatment/disposal options for PFAS-impacted biosolids, and regulatory considerations. Resources and further details for the topics included in this training are in the published PFAS-1 guidance document in Sections 2, 4, 5, 8, 10, 12, and 17.3, and the Regulatory Programs Table.
