PFAS are a group of more than 5,000 man-made chemicals that are resistant to heat, water, and oil.
PFAS are used in an extensive array of manufacturing processes and are found in a wide-ranging variety of products including firefighting foams, consumer products, textiles, and carpeting. These chemicals have been found to be ubiquitous, persistent, and potentially toxic. Today, sites around the world may have PFAS contamination from many different sources. Traces of these chemicals are now showing up in groundwater sources and can also be present from legacy use of these compounds, even if the use of the PFAS-containing materials has been discontinued. An increasing number of states and municipalities are conducting drinking water, groundwater, surface water and soil sampling to determine PFAS levels in these media, and EPA has conducted two rounds of drinking water supply sampling under the Safe Drinking Water Act. The regulatory framework and science of PFAS are rapidly evolving, with several rule packages destined for publication in 2024.
TRC’s Liz Denly and Laura Trozzolo will cover the following topics during this presentation:

- Sources of PFAS
- Major & minor sources and uses of PFAS
- Typical sites with PFAS contamination
- Sources of PFAS in indoor environments
- Routes of Exposure and Toxicology
- Indoor residential exposure
- Worker exposure
- Current air standards for PFAS
- Available analytical methods for water, air, and products
- Sampling water supplies for PFAS
- Case study: communicating potential PFAS risk to the public
- PFAS in Dust and Air: summaries of what we know
