In most cases, water is neither useful nor harmful. It is simply necessary.
For certain diseases and conditions, certain mineral water may be useful. In other cases, just try to drink at least a few glasses of water a day (8 is not necessary - this recommendation is not well founded).
Drinking a lot is desirable in case of viral and respiratory diseases. In other cases, you just need to drink.
Better from a puddle than urine. Better from the tap than from a puddle, better filtered (but not all, by the way) than from the tap. Better spring water than filtered water.
Bottled water most often does not differ in essence from filtered water, and even from the one that sometimes comes from the tap.
But this advice from microbiologists: if you drink from the tap - skip the stream of water for a couple of minutes before drinking (if the water has been turned off for a long time, for example, after the night). With water meters, this, of course, was not so profitable, but it's worth it.
Aquaphoric water, this is filtered water, there is hardly anything useful in it. Boiled water will also not be useful, because it has undergone heat treatment (you have killed everything useful and harmful with temperature). From the tap is controversial, since water is more often with disinfection products. Only when I was in Central Asia was it possible to drink from the tap so boldly.
