You can't really "filter" out these chemicals when they're fully dissolved in the water.
There's always distillation, but that's not practical at all on the scale of drinking water for cities.
Reverse osmosis is the other option, but it's also not cost-effective at city scale.
Ah, good point. Forgot about that one haha.
I had thought activated charcoal could remove the chemicals. No I don't mean city scale. I meant after the water comes out of the tap but before you drink it. City water has to be treated to not harbor too many germs.
