Here is a quick water test done in Cottesloe on the 19/3/2023 between 3.35 - 3.40pm.
The results are entirely consistent with other water tests completed around Western Australia in recent weeks.
The water forms a black layer once electrolyses commences and this black layer is magnetic post electrlyzation. Once left to settle for a couple of hours it becomes a rusty black mud in the bottom of the glass.
Rottnest visible in the background for reference.
If your in Western Australia or anywhere for that matter - test the water for yourself.
