What is the difference between spring water, purified water, distilled water and drinking water?
Distilled water is water that has virtually all of its impurities removed through distillation. Distillation involves boiling the water and re-condensing the steam into a clean container, leaving most contaminants behind. Purified water can come from any source, including spring water, well water, seawater, or municipal water. This source water is then processed by reverse osmosis or deionization to produce a water that is indistinguishable from distilled water from any other source. Purified water contains no dissolved solids. Purified water may also be unhealthy because minerals and ions are being pulled out of it due to reverse osmosis. The human body needs ions for the brain to function properly. Many of these ions are attained through water, often under the name electrolytes. Distilled and purified water lack these ions, so prolonged ingestion of distilled or purified water may lead to brain malfunction. A spring is a point where groundwater flows out of the ground, and is thus wh
