PFAS Analytical Approaches for Dynamic Work Strategies: Definitive vs. Screening, Or Better Yet, Both!
By Mike Rossi, Pace Analytical
Over the last two decades, the benefits of using mobile laboratories (inter alia) to support dynamic work strategies at sites contaminated with chemicals such chlorinated solvents and petroleum hydrocarbons has been demonstrated at many sites. Building on this practice, the industry is now starting to use these same work strategies and technologies at sites that are contaminated with per- and polyfluoroalkyl substances (PFAS). Depending on the data quality objectives (DQO) for a given PFAS project, the decision regarding whether a definitive, screening level, or collaborative analytical framework will need to be decided early in the project planning stages. The purpose of this article is to provide guidance for choosing the appropriate level of analytical data quality and to inform the reader regarding what analytical techniques are available.
