Morphology

hard + water

The adjective 'hard' could lead a learner to infer 'not soft' when combined with 'water', so there is a partial, compositionally motivated link. However the specific technical sense (high calcium/magnesium content that prevents lathering) is a specialized, non-literal property that a B1 learner would not reliably infer from the constituents alone.

Etymology

The term hard water comes from an everyday image: hard water is water that has minerals in it which stop soap from making bubbles and leave hard white deposits on kettles, so the water is 'difficult to use' with soap. That's why hard water means water with a lot of calcium and magnesium that makes soap work poorly.
