Relationship between Tap Water Hardness - Europe …

We calculated tap water hardness for each postal code using information obtained from all pumping stations in the Netherlands. Tap water hardness was egorized as soft [< 1.5 mmol/L calcium carbonate (CaCO 3)], medium hard (1.6–2.0 mmol/L CaCO 3), and hard (> 2.0 mmol/L CaCO 3). The multivariate case-cohort analysis was based on 1,944 IHD

Glossary: Water hardness - GreenFacts

2019-4-26 · The term "hardness" comes from the fact that it is hard to get soapsuds from soap or detergents in hard water. This happens because calcium and magnesium react strongly with negatively-charged chemicals like soap to form insoluble compounds. As a result, hard water can reduce the effectiveness of the cleaning process.

Water Hardness and Alkalinity - USGS

Water Hardness. Many industrial and domestic water users are concerned about the hardness of their water. Hard water requires more soap and synthetic detergents for home laundry and washing, and contributes to scaling in boilers and industrial equipment. Hardness is caused by compounds of calcium and magnesium, and by a variety of other metals.
