2. Supercritical water oxidation - Wikipedia

   en.wikipedia.org/wiki/Supercritical_water_oxidation

   Supercritical water oxidation (SCWO) is a process that occurs in water at temperatures and pressures above a mixture's thermodynamic critical point. Under these conditions water becomes a fluid with unique properties that can be used to advantage in the destruction of recalcitrant and hazardous wastes such as polychlorinated biphenyls (PCB) or ...

   Nonetheless, diverse methods are being tested including sonolysis, electrochemical oxidation, advanced oxidation processes, as well as the use of oxidative enzymes (such as peroxidase and laccase). [2] All of these methods promote the formation of hydroxyl radicals or other oxidizing agents that can oxidize PFAS and break its C−C bonds.

   USGS map showing the number of PFAS detections in tap water samples from select sites across the US. In April 2024, the EPA issued a final drinking water rule for PFOA, PFOS, GenX, PFBS, PFNA, and PFHxS. Within three years, public water systems must remove these six PFAS to near-zero levels. States may be awarded grants up to $1 billion in aid ...

   One of twenty deer tested near Clark's Marsh was found to have a PFOS level of 547 parts per billion (ppb) taken from a muscle sample. It is unknown how PFAS could accumulate to the level seen in the deer found near Clark's Marsh. All deer except the one with elevated levels at Clark's Marsh were found to have no or very low levels of PFAS ...
