Remove chlorine from tap water.

Do you know WHY they use chlorine and what it was like before they started using it? If they removed chlorine you get to deal with all sorts of waterborne diseases and bacteria. The level of chlorine in tap water is extremely low and what’s left mostly evaporates away.
