> Edinburgh water is hard, with notably high sulphate

No it isn't. Where did they get this?

> Calcium 100 mg/L Magnesium 20 mg/L Hardness: 332 as CaCO₃

Actual data: https://www.scottishwater.co.uk/-/media/scottishwater/docume...

has five sampling points at https://en.wikipedia.org/wiki/Glencorse_Reservoir (Edinburgh's drinking water supply)

    Zone        Ca mg/l  Mg mg/l CaCO₃ mg/l Hardness
    Glencorse A 10.04    1.31    30.44      Soft
    Glencorse B 10.36    1.36    31.44      Soft
    Glencorse C 10.04    1.35    30.60      Soft
    Glencorse D 10.16    1.35    30.90      Soft
    Glencorse E 10.06    1.34    30.61      Soft

They're wrong by a factor of 10 to 20.

How can I trust any other page on the site, if I check one and it's completely wrong?

What it's showing is the water profile historically associated with brewing Edinburgh and Scottish ales, rather than Edinburgh's current tap water profile. But yeah, it should be much more clear about this.

Oh, dammit. Unbookmarks

It was a good concept. Somebody should make it.
