PFAS Data Validation: A Technical Perspective
Over the past 30 years, the EPA and the DoD have identified emerging contaminants. A current group of contaminants are Per-and Polyfluoroalkyl Substances (PFASs). As testing for these contaminants expands, laboratories have been confronted with developing applicable analytical procedures to produce high quality data. Data validation has become a critical component of the EPA and the DoD data quality processes. This presentation will highlight the most current status and process for data validation of PFAS methods and results relative to these guidelines. It will provide a perspective on the path moving forward in PFAS data validation and how it relates to the DoD/DOE QSM 5.3 and the DoD PFAS Data Validation Guidelines. We will walk through critical elements in the DoD/DOE QSM 5.3 document and how DoD data validation guidance specific to PFAS analyses will foster consistency in validation and reporting of PFAS data for DoD projects.
