  Reverse osmosis water filtration systems that use activated carbon are pretty common, and least where I live. We have one under our kitchen sink, and so do my in-laws. Most refrigerators that include a water dispenser come with an activated-carbon-based water filter as well.

    That's nice that you've got that in your home. But at scale? For the rest of us? I live in a "developing nation" [0] of 70 million people whose private water companies are fined billions every year because they cannot meet the most basic standards of supplying potable water and not dumping raw sewerage into the rivers and sea.

      I’m not sure what point you’re trying to make anymore. You asked if people actually have these things. We do. Why does this need to scale? If you want to be pedantic, anyone can make themselves an activated charcoal water filter using fire, wood, half a plastic bottle and some rocks and straw and stuff. If you’re on the Internet you already have access to this knowledge.
