PFAS Technical Update: Avoiding costly errors in PFAS sampling

Per- and polyfluoroalkyl substances (PFAS) are a class of human-made chemicals that have attracted significant attention in the last few years from the regulatory community, industry, and general public. But it is crucial to carefully modify conventional sampling techniques for PFAS analysis because manufacturers use PFAS to produce a variety of industrial, commercial, and consumer products, and the possibility of false positives from contaminating the samples is high.

Further, laboratory detection limits and current regulatory threshold concentrations for PFAS are very low-in the parts per trillion (ppt) range. Haley & Aldrich staff reviewed and considered guidelines from several regulatory agencies and developed a detailed and standardized operating procedure (OP) for collecting soil and water samples for PFAS. For a summary of the best practices in Haley & Aldrich’s OP, read our PFAS Technical Update: Avoiding costly errors in PFAS sampling.
