As a child growing up we lived on a 25 household water system in the Sierras of California. The Sierras are made of mainly granite and is riddled with radioactive materials. When granite decomposes it puts off radon gas which is trapped in the ground water. One of the wells on the water system had such a high level of radon gas that the EPA came out in their full hazmat suits to test the well that 25 households had been drinking water from for over 10 years. That water was shown to have over 200K p/l with a max accepted level of 20 p/l. Th running joke of the families was that we don't need a night light since we were drinking radioactive water. But in reality the radon gas mostly dissipated with aeration and was lost to the atmosphere. We started aerating the water in the system to reduce the overall radon level which helped immensely but eventually had to abandon the well.
My grandmother co-owned a hotel near the Yosemite entrance at a mile high elevation. The drinking water we would haul in gallon and 5 gallon jugs had a super high mineral content and was a hard water from an artesian well. It had a taste. The taste of minerals. Real healthy water has a taste, it tastes of minerals. Humans are not meant to drink sterilized water, we need water with minerals. That is why things like Fiji water put minerals into their water to give it the flavor of REAL water.
Minerals are preferably added most times in cases of malnutrition or mineral deficiency so as to complement the deficit.
Normal water meant for drinking is not expected to have taste.
You must not have drank from a stream or fresh water from a well. Purified water is the only water to have no taste. Taste is created by minerals which are essential to healthy water.
