Understanding Usability of PFAS Data (webinar)

Tuesday, May 4, 2021
1:30 PM

Please join NEWMOA for a webinar on the potential inconsistencies in how samples are prepared and analyzed for poly- and perfluoroalkyl substances (PFAS) and how usablity of the data might be affected. 

1:30 to 3:00 (Eastern) 


  • Dr. Nancy Rothman, Chief Executive Officer, New Environmental Horizons, Inc.
  • Elizabeth Denly, Quality Assurance & Chemistry Director, TRC

It is well understood that the analysis of PFAS is being performed using liquid chromatography/dual mass spectrometry (LC/MS/MS). Currently, the majority of laboratories are utilizing a modified version of EPA method 537, which was designed for drinking water samples. EPA is in the process of developing methods for non-drinking water matrices but these methods are not yet available. There is no consistency in the laboratory community with regards to the modifications that are implemented, how the samples are prepared, quality control procedures, and whether or not sample cleanups are performed. Data users need to understand the modifications laboratories are implementing or not implementing in order to determine whether data quality objectives are being achieved.

This presentation will provide hands-on training in how to assess PFAS data and will provide the data user with appropriate sampling and method information to communicate effectively with a laboratory to obtain PFAS data that meets their project needs. Additionally, this presentation will provide training on the impact of Quality Control (QC) issues including assessment of method and matrix QC results on PFAS data. With this information, data users will be able to evaluate the information they receive to determine the accuracy, precision, and ultimate usability of their PFAS data.
