About This Webinar:

PFAS are a family of synthetic fluorinated compounds which have been mass produced in the United States for decades, dating back to the 1950s. PFAS are used in a wide variety of industrial and commercial applications such as textiles, aqueous film forming foams (AFFF), metal plating, semi-conductors, paper and food packaging, coating additives, cleaning products, pesticides and personal care products. According to U.S. EPA, PFOA and PFOS pose potential adverse impacts to the environment and human health due to the bio accumulative and persistent nature of the compounds.

Production of the “legacy” long carbon chain molecules was largely phased out beginning in 2002 and over the course of the next thirteen years. The manufacturing of the next generation of fluorinated chemicals has brought new PFAS chemicals to the forefront of our discussions, but little is known about their potential impact to human health.

The chemistry of PFAS is unique and challenging. There is currently no consensus best method for all environmental matrices and compounds of concern but a multitude of varying approaches. This soup of non-validated methods and analytical approaches has left stakeholders with the challenging job of navigating their options and making the right choice for their project objectives.

In the absence of federal regulation and guidance, and alongside the variations in analytical techniques, we see growing variation in actions being taken at the State level. States have proposed or promulgated limits for various compounds, all being different from one another, and for differing matrices or programs.

Topics the Presentation Will Cover:

  • A review of the chemistry and nomenclature

  • An introduction to precursors and replacement chemicalsSources of PFAS in the environment

  • Exposure pathways and risk

  • A glimpse of the varied guidance and regulation that is available nationwide

  • Discerning between the various analytical approaches

  • Evaluating sampling protocols and best practices
