2. Hard water - Wikipedia

   en.wikipedia.org/wiki/Hard_water

   Hard water is water that has a high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum, [1] which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates. Drinking hard water may have moderate health benefits.

3. Water softening - Wikipedia

   en.wikipedia.org/wiki/Water_softening

   Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes

4. Drinking water - Wikipedia

   en.wikipedia.org/wiki/Drinking_water

   Local geological conditions affecting groundwater are determining factors for the presence of various metal ions, often rendering the water "soft" or "hard". [citation needed] In the event of contamination of drinking water, government officials typically issue an advisory regarding water consumption.

   In the European Union, bottled water may be called mineral water when it is bottled at the source and has undergone no or minimal treatment. [4] Permitted is the removal of iron , manganese , sulfur and arsenic through decantation , filtration or treatment with ozone -enriched air, insofar as this treatment does not alter the composition of the ...

7. Total dissolved solids - Wikipedia

   en.wikipedia.org/wiki/Total_dissolved_solids

   When measuring water treated with water softeners, high levels of total dissolved solids do not correlate to hard water, as water softeners do not reduce TDS; rather, they replace magnesium and calcium ions, which cause hard water, with an equal charge of sodium or potassium ions, e.g. Ca 2+ ⇌ 2 Na +, leaving overall TDS unchanged [9] or even ...
