Our waterways are becoming more and more polluted due to PFAS, plastics, medicines, drugs, and new chemicals made by companies that just hand over the responsibility of cleaning to plants paid for by public moneys. Detecting the different chemicals and filtering them out if getting harder and harder. Could the simple solution of heating up past a point where even PFAS/forever chemicals decomposes (400C for PFAS, 500C to be more sure about other stuff) be alright?

            pesticides, pharmeceuticals, PFAS or forever chemicals. all can be made much worse by boiling at over 500c, just forna few examples.

              For PFAS that definitely isn’t true

              In the new EPA study, experts added oxidizing substances to water contaminated with PFASs and heated the liquid above its critical temperature of 374 degrees Celsius at a pressure of more than 220 bars. During this process, the water becomes what is called supercritical: it is neither a gas nor a liquid. In this state, even water-repellent substances such as PFASs dissolve much more readily, and at the same time, the state accelerates chemical reactions.
