A possible solution for PFAS-contaminated wastewater treatment has been developed by the Michigan State University-Fraunhofer team. Boron-doped diamond electrodes are used for the electrochemical oxidation system where it is capable of breaking PFAS molecular bonds which essentially eliminates the contaminates, leaving fresh water.

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 ...
The standards, enforced by EPA and state agencies, require all public water systems in the U.S. to monitor for GenX and treat their water, if necessary to meet the 10 ppt standard. [43] EPA also announced the availability of grant funds to assist small and disadvantaged communities in testing for and treating PFAS contamination in their water ...
A water sample is measured as part of a PFAS drinking water treatment experiment, Tuesday, Feb. 14, 2023, at the U.S. Environmental Protection Agency Center For Environmental Solutions and ...
At-home filtration solutions can cost as little as $20, but as feature sets and capabilities grow, so does the cost. ... there are three primary filter types used to remove PFAS from drinking ...
Where will I find PFAS chemicals? In 2023, the U.S. Geological Survey estimated that 45% of America’s tap water contained one or more of the 32 specific PFAS compounds it tested for, including ...
A new EU drinking water directive issued in 2020 adopted PFAS limit values. The limit values are 0.1 μg/L for the sum of 20 PFASs including PFHxS, and 0.5 μg/L for the sum of all PFASs. This directive is binding for all EU member nations. It is a minimum directive, and member states can elect to adopt stricter regulations. [19]
Perfluorobutanesulfonic acid (PFBS) is a PFAS chemical compound having a four-carbon fluorocarbon chain and a sulfonic acid functional group. It is stable and unreactive because of the strength of carbon–fluorine bonds. It can occur in the form of a colorless liquid or a corrosive solid. [1]
