What does clean water contain?

Clean water primarily contains H2O molecules, free from contaminants such as bacteria, viruses, heavy metals, and harmful chemicals. It may also contain essential minerals like calcium and magnesium in trace amounts, which can contribute to its taste and health benefits. However, the specific composition can vary depending on the source of the water and any treatment processes it has undergone. Clean water should meet safety standards set by health organizations to ensure it is safe for drinking and other uses.
