I understand the desire for convenience and a single "Grab & Go" container, but knowing what water can do, why pack it in the same container as non-water containing items.

Since the water could burst from any number of reasons from any container, it seems a better bet to pack it in its own easily identifiable (IE: Different color or water printed on the container.) container so that even if you only have time to Grab & Go with one container, you can make your choice at the moment of need.
