Canning Water in Half Gallon jars.
Heat Treatment: One effective way to store water is in clean canning jars. Fill clean Mason-type quart or half-gallon jars with water, leaving 1 inch of headspace at the top of the jars. Attach two-piece metal canning lids. Fill a boiling water canner half full of water and preheat the water to approximately 140° F. Place jars into the water bath. Add more boiling water if necessary so that jars are covered by 1 inch of water. When water returns to a rolling boil, process jars for 20 minutes. Remove jars from the canner and allow them to cool. After seals set, remove screw bands and place jars in storage. Canned water often will have a white mineral precipitate or ring at the water level. This is normal.

I think this is a safe method posted by a university extension, however previously I thought only canning two types of Juice were able to be canned in half gallon jars. Would you do this?
