They claimed it for geography, as an advance due to their subject.

There's a post in there, -1 (or is that a rating?) which agrees with what I'm saying.

The World Health Organization says that “there does not appear to be any convincing evidence that water hardness causes adverse health effects in humans.”[7]

Some studies have shown a weak inverse relationship between water hardness and cardiovascular disease in men, up to a level of 170 mg calcium carbonate per litre of water. The World Health Organization has reviewed the evidence and concluded the data were inadequate to allow for a recommendation for a level of hardness.[7]

Recommendations have been made for the maximum and minimum levels of calcium (40–80 ppm) and magnesium (20–30 ppm) in drinking water, and a total hardness expressed as the sum of the calcium and magnesium concentrations of 2–4 mmol/L.[8]

Other studies have shown weak correlations between cardiovascular health and water hardness.[9][10][11]

Some studies correlate domestic hard water usage with increased eczema in children.[12][13][14]

The Softened-Water Eczema Trial (SWET), a multicenter randomized controlled trial of ion-exchange softeners for treating childhood eczema, was undertaken in 2008. However, no meaningful difference in symptom relief was found between children with access to a home water softener and those without.[15]
