Funny sort of question ???
Where would it go?
If you mean could it cease to be pure water, ask yourself where any contamination would come from.

In the right container and air tight it could last for years.
Thank's Ewan ;)

I assume you mean it will develop algae, Ian? If the container is clean prior to filling, and is then filled to the top and an airtight cap screwed on it will remain pure. Our definition of 'pure' is that it contains no "dissolved solids". In order for it to become "impure" i.e. acquire a higher TDS reading there has to be a source of soluble solid material. The is no such source in the above scenario, so the TDS will remain the same.

Algae yes Ian, I have some out side in the sunshine I will keep a check on them, they are not being used so will be interesting as there is no way I can get them air tight or should I say with no air in the barrell :-\
