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. Crystal Geyser® Alpine Spring Water® contains only spring water made as nature intended, pure and natural, from the protected spring sources. It comes directly from the earth. Crystal Geyser® 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.
