I have a well at the cottage and I draw water from it into the cottage. So the well is pumped daily (I live there). I make coffee from that water in the well. But only now, after a year, did I wonder if I could catch something out of the water. But when I boil it, the chances of infection should be minimal, right? It's secluded in the mountains. There must be water like ****, right? Fix it for me.
