eli5: When people used wells for drinking water, how did they not get sick? Was there some type of filter or was the water just naturally clean?

Yes, ancient cultures had filters using things like sand. However if we’re talking about bacteria, boiling solved most issues. Water was also commonly made into herbal teas, beer, wine etc. alcohol contents were much much lower ie 1-3% so you could drink all day.
