I had the opportunity, no, it was actually stupidity at that time, to drink “pure, natural” water. (Should have boiled it first) Be assured that amoebic dysentery is not fun, especially with medical facilities at two day’s walking distance. I did learn, though, that drinking soy sauce lessened the impact of my stupidity.
Hasn’t anyone heard the old advice, “don’t drink the water” in Mexico, et al?
And it was known long ago the best way to handle water was to boil it first. When people did not understand that, they didn’t drink straight water much but that is how they got into beer and wine. Not realizing the fermenting and cooking was making it safer.
Does it come from a properly constructed well or out of a nearby stream? If it’s a well it should be no problem unless the aquifer is contaminated. What’s more likely is to get sick from contaminants at the delivery spigot.
Never drink untreated surface water
