League table

The hardest waters

155 waters ranked by hardness (CaCO₃ equivalent) — the limestone league table.

Hardness sums calcium and magnesium as a CaCO₃ equivalent — the number kettles and espresso machines care about, and the chalky backbone you can taste. The gypsum-spring giants at the top are, quite literally, drinkable limestone.
