I live at the beach and drink city water filtered through a filter that hooks onto my faucet. I've noticed if I leave water in a glass overnight, it gets a mark all the way around the glass at water level. The locals have said this is because it is "hard water". Is it safe to drink? I'm giving Sierra bottled water just in case. On that topic, which is better for her, "spring water" or "drinking water"?
