Looks good, but probably not very usable. I know some areas in germany, where you cannot drink the water because of too much chalk. But in general it is very good in germany.
But in spain for example I could never find a tab, I could drink of - way too much chlorine.
That's a good point, I think it very much depends on the area you are in, that's why I added sub-pages for each country, e.g. https://www.iswatersafetodrink.in/germany/Munich. Although to be fair they are still lacking serious data, I'm working on that!
Well, for me, that would be allmost the same, as I believe taste has a biological reason, as a strong indicator whether something is good or bad for my health.
(no, pure sugar does not taste good for me)
But officially science says currently no, chalk in water is not a health issue and maybe even good.
(but I would not be surprised, if that changes in the future, like with many other things)
