If you want "raw water" then buy water that is labeled as "spring water" this flows directly from the earth from a spring, if your bottled water does not say "spring water" like "Dasani" or other major brands then you are drinking purified tap water that has been processed in many ways. Personally though I think all bottled water tastes like plastic and I prefer to filter my own tap water with a Pur filter which has a cartridge option that will remineralize your water so it tastes good and does not make you thirsty like overly pure water will do. That's why you don't really want to drink distilled water.
