PFAS - Perfluoroalkyl and polyfluoroalkyl substances - Public Health
Sep 30, 2024 · Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are synthetic chemicals. They have been released from aqueous film forming foam used to fight fires.
Aqueous film-forming foam (AFFF) is a highly effective firefighting product intended for fighting high-hazard flammable liquid fires. AFFF products are synthesized by combining hydrocarbon foaming
PFAS Destruction and Near-Complete Defluorination of Undiluted Aqueous …
2 days ago · The nonthermal destruction of aqueous film-forming foam (AFFF) stockpiles, one of the major culprits responsible for water and soil contamination by per- and polyfluoroalkyl substances (PFAS), is extremely challenging because of the coexistence of mixed recalcitrant PFAS and complicated organic matrices at extremely high concentrations. To date, the complete defluorination of undiluted AFFF at ...
Near-complete destruction of PFAS in aqueous film-forming foam …
May 1, 2024 · Aqueous film-forming foam (AFFF) for the suppression of fuel fires is a major cause of widespread and heavy water environment pollution by per- and polyfluoroalkyl substances (PFAS)...
Interim Guidance on the Destruction and Disposal of PFAS and …
Oct 8, 2024 · The FY20 NDAA directed EPA to address the destruction and disposal of PFAS and specific PFAS-containing materials, including aqueous film-forming foam, contaminated media, textiles (other than consumer goods), and various wastes from water treatment.
Identifying and Managing Aqueous Film‐Forming Foam‐Derived …
Oct 7, 2020 · The use of aqueous film-forming foam (AFFF) has resulted in the widespread occurrence of per- and polyfluoroalkyl substances (PFAS) in groundwater, drinking water, soils, sediments receiving waters, and wildlife throughout the United States and globally.
Removal of Per- and Polyfluoroalkyl Substances (PFASs) in Aqueous Film …
Mar 22, 2021 · Despite benefits to the firefighting industry, the release of per- and polyfluoroalkyl substances (PFASs) from aqueous film-forming foam (AFFF) into aquatic systems poses significant risks to human health and other organisms.
Near-Complete Destruction of PFAS in Aqueous Film-Forming Foam …
Aug 28, 2023 · Aqueous film-foaming foam (AFFF) for fire-fighting is a major source of PFAS pollution. However, complete defluorination (i.e., cleaving all C−F bonds into F− ions) of PFAS by a non-thermal technology is rare.
Firefighting Foam: DOD is Working to Address Challenges to ...
Jul 8, 2024 · The Department of Defense (DOD) has taken steps to eliminate use of aqueous film-forming foam (AFFF)—a product used to fight flammable liquid fires—at its installations. AFFF contains per- and polyfluoroalkyl substances (PFAS), which may have adverse effects on human health, including effects on fetal development, the immune system, and the ...
Firefighting Foam and PFAS - State of Michigan
There are two major classes of firefighting foam: Class A and Class B. Class B is also called Aqueous film forming foam (AFFF) and is usually created using PFAS. It is a highly effective foam used for fighting high-hazard flammable liquid fires, like gasoline, oil, and jet fuel.
