ABOUT THIS WEBINAR:

This webinar was previously recorded with a live question & answer session.

Many sites have been required to add the analysis of Per-and Polyfluoroalkyl Substances (PFAS) to their ground water sampling plans. Military bases, airports, landfills and manufacturing facilities are sites where PFAS contamination may be present due to the use of PFAS in activities such as fire suppression or plastic manufacturing. Collecting samples for PFAS is very different from sampling for fuels, solvents, and other chemical contaminants, as potential sources of PFAS are nearly everywhere - in waterproof clothing and field gear, personal care products, and sampling equipment. But, is there really a risk from all of these sources? Do we need to eliminate all of these items to avoid sample contamination? And what about fluoropolymers like Teflon that have been used in sampling equipment for more than three decades? Can we use these systems to collect samples for PFAS analysis or do we need new equipment that is entirely free of all fluoropolymers?

Currently there are no EPA approved methods for the collection and analysis of PFAS in matrices other than finished drinking water. For all other matrices, a user-defined method and protocols must be used. As there is no standard method for sample collection, handling, or quality control measures, specific attention must be paid to the protocols employed by the laboratory and the field sampling team.

In this webinar, David Kaminski with QED Environmental Systems will explore the sources of PFAS sample contamination and dispel some of the myths and speculation surrounding the issue. Taryn McKnight with Eurofins Environment Testing America (EETA) will illuminate the multitude of parameters and best practices to adopt when employing a user defined method.

PRESENTATION WILL INCLUDE:

  • A review of published guidance
  • A review of published studies evaluating sources of PFAS
  • Sampling system materials - what works, what doesn't?
  • Avoiding obvious sources of contamination
  • PFAS free DI water and sample containers

A question and answer session will immediately follow the presentation.

SPEAKER:

David Kaminski is Senior Vice President of QED Environmental Systems and is a frequent presenter on groundwater sampling technology to organizations, universities, and regulatory agencies worldwide.  He has been awarded four U.S. patents for developing new devices and methods for groundwater sampling applications and is an instructor at the Princeton Groundwater Pollution & Hydrology course (www.princeton-groundwater.com) Over the past 34 years he has published several papers on groundwater sampling practices and sampling system design and has presented these topics at over a hundred conferences, seminars and field courses.

 

SPEAKER:

Taryn McKnight is PFAS Practice Leader for Eurofins Environment Testing America based in Sacramento, California. She has more than 20 years of experience in the environmental testing industry. Ms. McKnight is a Subject Matter Expert on Vapor Intrusion. She has extensive experience with a wide variety of complex regulatory programs such as DoD, Vapor Intrusion, and emerging contaminants such as PFAS. In her current role she is responsible for providing technical guidance and support to clients, agencies and industry personnel across the country.
