Local reservoirsandmunicipal water suppliesmight become so polluted from the fires that the current water supply infrastructure will be challenged or could no longer treat the water.

Flash floods and water contamination after large-scale wildfires are emerging as real hazards in Australia and many other places, threatening drinking water, ecosystems, infrastructures…
