Contaminated Site Clean-Up Information (CLU-IN): Internet Seminar Audio Archives

This ITRC training course will build upon PFAS sampling and analysis information presented in the PFAS 101 CLU-IN training. The ITRC PFAS Beyond the Basics class provides in-depth information on preparing for and implementing sampling events. Some detailed information and case studies are presented for sampling surface water and PFAS-containing foam that can form and aggregate at the surface water-air interface. The training includes information about PFAS analysis and discusses alternative qualitative analytical techniques. The occurrence of PFAS in air information from the literature for outdoor air, indoor air, settled dust and precipitation is discussed. Resources and further details for the topics included in this training are in the ITRC Guidance Document (PFAS-1) in Sections 6, 11, 15, 16 and 17.1 along with referenced tables. Learning Objectives:Key elements that make sampling for PFAS different from other sampling events.Best practices for preparing and conducting a PFAS sampling event.Matrix-specific PFAS sampling guidance.Surface water/foam sampling challenges and case study.Options for compound-specific PFAS analysis and key differences of available methods.Understanding PFAS analytical challenges (suspended solids, branched/linear isomers, bile salt interference).Qualitative analytical techniques and when they can be useful.Occurrence of PFAS in air.
