Well water is MUCH more cost effective than city water and the quality of water is likely a push. Cities typically add a bunch of chemicals to treat the water they pump out of polluted resources. Country water is more natural, but could contain unfiltered pollutants and natural sediments. If you want clean water, you need to properly treat it yourself no matter where you live. And the result coming out of your faucets is also heavily reliant on the condition of the pipes in your house.
