I'm still curious about the drinking safety question though.


Removing the water from it's usually cooler source such as a lake or stream and leaving it untreated in an environment such as a water bottle that is subject to potentially warmer temperatures, would all in probability cause the bacteria count to increase. How much of an increase is the question, but I would think that any of the straws or chemical treatments such as MicroPur would still suffice.
