As groundwater professionals, we are called on to sample for PFAS analysis and to interpret PFAS laboratory data. The presence of PFAS in many products, potentially including products commonly used in environmental field sampling efforts, should be considered when planning a PFAS sampling program. Understanding the actual versus the perceived risk that any material or process may present is a key component of developing a sound Sampling and Analysis
Plan or Quality Assurance Project Plan (SAP/QAPP).
This guidance document from the National Groundwater Association aims to provide practical guidance to PFAS sample collection for those already familiar with industry-standard environmental field sampling practices.
