March 2018 The United States Department of Defense's (DoD)'s report to Congress said that test that they conducted showed that the amount of PFAS chemicals in water supplies near 126 DoD facilities, "exceeded the current safety guidelines". [71] The DoD has "used foam containing" PFAS chemicals "in exercises at bases across the country".
The CompTox Chemicals Dashboard is a freely accessible online database created and maintained by the U.S. Environmental Protection Agency (EPA). The database provides access to multiple types of data including physicochemical properties, environmental fate and transport, exposure, usage, in vivo toxicity, and in vitro bioassay.
The state also set a PFOS standard at 13 ppt. [24] The state had set a standard for PFNA in September 2018, with an MCL of 13 ppt. [25] [26] In August 2020 the State of Michigan adopted drinking water standards for 5 previously unregulated PFAS compounds and lowered acceptable levels for 2 previously regulated compounds PFOS and PFOA to 16 ppt ...
In February 2023 the federal government announced a $2 billion effort to combat “emerging contaminants” − such as PFAS − in disadvantaged communities, and the EPA says that program offers ...
A water researcher tests a sample of water for PFAs, Tuesday, Feb. 14, 2023, at the U.S. Environmental Protection Agency Center for Environmental Solutions and Emergency Response in Cincinnati.
Long-chain PFAS chemicals perfluorooctane sulfonic acid, or PFOS, and perfluorooctanoic acid, or PFOA, are among the most studied of the nearly 15,000 types of PFAS used by industry.
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 ...
PFAS have been a subject of multiple lawsuits worldwide. [245] [246] [247] In the United States, settlements stemming from PFAS pollution claims have reached $18 billion by 2024. [248] In 2023, Sweden's Supreme Court set a legal precedent by awarding damages to citizens who were supplied PFAS contaminated drinking water. [249]
