Definition from
antoine.frostburg.edu:
Hard water is water contaminated with compounds of calcium and magnesium. Dissolved iron, manganese, and strontium compounds can also contribute to the "total hardness" of the water, which is usually expressed as ppm CaCO3. Water with a hardness over 80 ppm CaCO3 is often treated with water softeners, since hard water produces scale in hot water pipes and boilers and lowers the effectiveness of detergents.
Example sentences:
Some laundry detergents do not produce as many suds in hard water, these are likely to be soap-based products and do not work as well in hard-water as detergent based products. (water-treatment.org.uk)
Hard water also contributes to inefficient and costly operation of water-using appliances. Heated hard water forms a scale of calcium and magnesium minerals that can contribute to the inefficient operation or failure of water-using appliances. (Wilkes University)
Clothes washed in hard water often look dingy and feel harsh and scratchy. (sciLinks)

L'aigua que no va bé per ensabonar rep el nom d'aigua dura i la que ensabona bé, aigua blana. (EduAlter)
L'aigua dura forma incrustacions que afavoreixen la corrosió de les canonades. També és la culpable de problemes d'obstruccions en valvulería i grifería, a més de malgastar els rendiments energètics dels escalfadors. (blautec)
