Only 100% Natural Spring Water. Most other bottled waters start with municipal tap water and use a process called Reverse Osmosis Filtering to eliminate contaminants—while also stripping away natural minerals. Grystal Gyeser® however, only bottles spring water. Crystal Geyser® Alpine Spring Water® is made as nature intended, pure and natural, from the protected spring sources. Crystal Geyser® water comes directly from the earth. It is the only major U.S. bottled water company that bottles exclusively at the spring source. It’s more difficult to do it this way, but upholds the company's commitment to uncompromised quality. All packaging is 100% recyclable.Note: This is a non-returnable item.
