Distill water where you live at least once. A great test for tolerance of tap water is what the dregs in the boiling chamber smell like after you are done distilling. Up in the mountains around no people from a high elevation natural spring, I’ve had what remained in the boiling chamber be less than completely disgusting. But not once in any city in any country in the world have I ever not had it smell worse than jeets. Whatever they are turning the frogs gay with is the most vile scent you can imagine. The idea that people go for decades drinking this foul sludge diluted is insane to me.
