Vapor Intrusion Potential of Select Per- and Polyfluoroalkyl Substances
Certain per- and polyfluoroalkyl substances (PFAS) have sufficient vapor pressures to be designated as vapor-forming chemicals and; thus, be a concern for vapor intrusion into the indoor air of residences and buildings overlying a contaminated soil or groundwater source. Multiple PFAS species, both neutral (e.g., …
