I saw somewhere on a youtube, that peoples' legs were swelling from a ship water, which would denote desalination not working well. I use RO at home too, with a remineralizer cartridge, since RO removes all minerals from the water and can have an acid ph. I'm asking this while I'm looking to add lots of ice to my canned Pepsi(can take the paint of of cars.LOL) on Carnival. LOL Thanks folks.

Are they made from the desalinated water, or shipped in, in bags?
