Not trying to derail your thread, just I'm curious now.

Once the bottle has been opened and some poured out, the empty space is now filled with the surrounding atmosphere. Depending on what happens to be floating in the air at that time, you can potentially introduce varying levels of spores, bacteria and other contaminants. Also, some plastic bottles are permeable to certain gasses/fumes, which could, over time, taint the water. Not to say that there will be a problem from having an old open bottle, but depending on conditions, the potential exists that there could be a problem.
