Chlorine. A molecule of chlorine has the ability to disproportionate in water. That is it simultaneously oxidises and reduces. Cl2 = Cl-Cl = Cl^(-) + Cl^(+) Disproportionation). Cl2 + H2O = HCl(reduced) + HClO(oxidised). At a water treatment plant, chlorine gas is bubbled through water, in order to act as a bacteriocide, so the water is drinkable/potable. Household water contains minute traces of hydrochloric acid(HCl) and hypochlorous acid(HClO). It is the hypochlorous radical 'ClO^(-)' that is found in bleach. (NaClO or Ca(ClO)2
There are only 2 elements in water: hydrogen and oxygen.

Drinking water straight from the mains water supply contains trace elements of Chlorine, and other elements deposited on its journey from the treatment plant. Distilled water has been boiled to the point that pure water vapour has been driven off, and collected - to make a pure water sample.

The only elements in pure water are those of which water itself is comprised ...hydrogen and oxygen. In impure water, any other elements that are themselvessoluble in water, or that are components of water-soluble compounds, or that areground up fine enough to be physically suspended in water, can also be found.
