You'd need to rework more than the worlds plumbing considering thats not even whats tainting things. The source says its often from runoff, from rain dissolving naturally occurring aluminum precipitated all over the earths crust and bringing it into the water supply. The only solution to that would be to distill all water. Imagine those energy costs.

My point is basically we are doomed for this, c'est la vie, live your life, probably something else will be taking you out at the end of the day anyhow.
