PFAS: Field Sampling & Cross-Contamination Issues
June 23, 2020 @ 1:30 pm - 3:00 pm
The webinar included the following presentations:
Anthony Drouin, Residuals Management Section, New Hampshire Department of Environmental Services (NH DES) [PDF]
- The NH DES Residuals Management Section (RMS) has been investigating PFAS in sludge/biosolids since 2016. Through these investigations, RMS has implemented annual PFAS screening into their Sludge Quality Certificate program. The presentation focused on sludge/biosolids PFAS sampling SOPs, issues faced when sampling sludge/biosolids for PFAS, and the lessons learned from the sludge/biosolids PFAS investigations
James Occhialini, Alpha Analytical [PDF]
- Presented an overview of analytical methods for PFAS; the current recommendations for PFAS sampling of environmental media which contain stringent provisions for products and materials to avoid potential cross-contamination. Is there a potential for PFAS to be transferred from common products used during sampling? The remainder of the presentation reviewed the results of a recently published study that investigated this potential
