It is commonly referred to as the main harmful PFAS chemical and PFOA is responsible for many of the negative health effects commonly associated with PFAS. Per- and polyfluoroalkyl substances are a group of synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain. Different organizations use ...
Water is a common route of exposure — drinking water from your municipal water sources in your home are contaminated with PFAS chemicals. Food can be another source of exposure, partly because ...
The DoD has "used foam containing" PFAS chemicals "in exercises at bases across the country". The DoD, therefore, "risks the biggest liabilities" in relation to the use of PFAS chemicals according to Politico. [71] March 2018 The PFAS Expert Health Panel on PFAS submitted their commissioned report to the Australian government. [89]
Public and media attention on PFAS contamination has largely centered on water sources, since it's one of the main routes of exposure for the general population.
PFAS are also found in paper mill residuals, digestates, composts, and soils. Given the ubiquity of PFAS, and the comparative background levels which may be found in wastewater, biosolids, and leachates, setting requirements near analytical detection limits on these sources may not provide a discernable benefit to protecting public health.

Fire-retardant foam, which contained PFAS compounds for decades, often found use at military bases and airstrips, causing costly pollution to nearby water sources. The U.S. Department of Defense ...
PFAS then accumulates the biomass in fish, wildlife, ecosystems and humans. Two of the primary compounds of concern, PFOA and PFOS, pose a host of potential risks, particularly to children and ...
All of these methods promote the formation of hydroxyl radicals or other oxidizing agents that can oxidize PFAS and break its C−C bonds. [3] [4] However, the remediation of PFAS depends on the environmental medium where the these compounds reside. For example, the treatment of contaminated soil, biosolids and water is not the same, and risk ...
