Natural Spring Water: Pure vs. Purified. Earth2o is water in its natural state. Uncomplicated. Uncompromised. Water this perf ... ect is worth sharing with the world. It comes from a single pristine source; Opal Springs in the heart of Central Oregon. Methodically filtered by time and thick layers of volcanic basalt. It isn’t “made” or manufactured in any way. To us, that’s “natural.” For other bottled waters, it’s not always so simple. Many other “natural” waters can come from above-ground sources (rainwater, rivers, etc.) but depend on surprisingly wasteful methods to become safe and drinkable. It gets better: Water made via reverse osmosis usually requires additional processing to “taste right”, with certain minerals added back to it before ultimately being bottled and shipped away. Without the right mineral balance, some “drinking waters” will actually remove important elements from your body over time, calcium being a big one. And you thought all water was just… water. So know where your water is really coming from—the source, the surroundings, the processes it’s put through. Be aware of the meaning behind the words and imagery. Safety is just as important to us as quality so we are proud to be certified by the NSF as a SQF 2000, Level 3 operation. This is the highest certification level possible-a level most water companies cannot brag about. That's how we "Keep it Real" at EARTH2O. For more detailed information see us at earth2o.com. read more
