PFAS Sampling & Analysis Webinar

Wednesday, August 3, 2016
1:30 PM

The Web Conference included the following presentations:

Dr. Jennifer Guelfo, State Agencies Liaison, Brown University Superfund Research Program
Analysis of Per- and Polyfluoroalkyl Substances (PFAS) [PDF]
Dr. Guelfo discussed analytical methods and limitations, and potential cross contamination challenges at laboratories when samples are analyzed for PFAS 

Dr. Dora Chiang, Vice President, Director of Emerging Contaminants at AECOM
PFAS Sampling [PDF]
Dr. Chiang addressed potential cross contamination and QA/QC measures when sampling for PFAS compounds 

PFOA and PFOS are perfluorooctanoic acid and perfluorooctane sulfonic acid, respectively and belong to the broader class of poly- and perfluoroalkyl substances (PFAS) that have been widely used for carpet and fabric protection, in food packaging ,and in metal plating, and have been included in products with familiar trade names Teflon, Gore-Tex, Stainmaster, and Scotchguard. In addition, PFAS were key components of aqueous film-forming foams (AFFF) widely used for firefighting. 

Several states in the northeast have sites where drinking water is impacted by PFAS. EPA recently issued a drinking water guideline of 70 parts per trillion and some NEWMOA states have set even lower numbers. Detection at such low levels presents many challenges both in the field and in the laboratory.
