Municipal water utilities (DEYA) in Greece usually combine boreholes in limestone aquifers with reservoirs and springs. The Rhodope mountains are mostly crystalline rock, which suits soft water. The reported hardness is 29.5 mg/L CaCO₃. Limescale is a minor issue here; a softener is unlikely to be necessary.
Greek utilities report total hardness in mg/L CaCO₃.
