ABOUT THIS WEBINAR:
Groundwater sampling for Per-and Polyfluoroalkyl Substances or “PFAS” is a topic that has generated more interest in our field of practice than any other topic in over three decades. Controlling sources of potential sample contamination for PFAS is more challenging than sampling for point source contaminants like fuels and solvents, as potential PFAS sources exist in commonly used supplies such as rain gear, sunscreen and insect repellent, food packaging and more. Early research into sources of PFAS that could potentially contaminate samples has led to guidance documents and SOPs that recommend or require the elimination of all Teflon and other fluoropolymers from sampling supplies and materials, including sampling equipment such as bailers, pumps and tubing, and passive and no-purge samplers. Research on the presence of fluorine in commonly used materials and supplies continues, but questions persist on what the results of some research means on a practical basis and if sites will be faced with potentially expensive replacement of existing sampling equipment. Is there really a risk from all of these sources? Do we need to eliminate all of these items to avoid sample contamination?
In this webinar, David Kaminski with QED Environmental Systems will discuss the history of the early guidance documents and industry practice recommendations, the latest materials research, and what options existing today for sampling materials and equipment.
PRESENTATION TOPICS WILL INCLUDE:
• Early PFAS sampling guidance and industry best practices recommendations
• Why have we used Teflon for so long?
• Is all Teflon bad for PFAS sampling?
• Are the recommended alternatives to Teflon good options?
• QED’s materials testing program and results to date
• Addressing Teflon in existing sampling equipment – concerns and recommendations
• Latest sampling equipment options for PFAS – pumps, tubing and passive samplers
The 40-minute presentation will be followed by a 15-minute Q&A session to answer your questions about PFAS sampling practices, materials options and more.
