>Some of us grew up on well water. It's generally fine, although you need to inspect and treat it regularly
You need to inspect it (the CDC recommends annually sending away for a water test[1]), but I'm aware of no EPA or CDC recommendation that calls for unconditionally treating the water. You treat well water only if the tests find a problem.
I can safely drink my well water, but it tastes a lot better if I treat it via my RO system.
My well water tests high for nitrates, as a healthy adult this is not a problem, but giving my water to babies will kill them. By only drinking the treated water I make accidents less likely because all my habits are to tell people don't drink the water except for the filtered drinking water.
