It's too bad other Alkaline waters are designed in a laboratory and then artificially processed. They essentially use filtered tap water, add minerals, and then electrocute the water to make it Alkaline. Yuck! Eternal Water is different because our water comes from Naturally Alkaline Springs. We add nothing to our water. It arrived in this bottle as nature intended - Eternally Perfect. Spring Source. Natural pH 7.8 - 8.2 (Approximate pH at time of bottling. Actual pH can vary due to natural fluctuation). eternalwater.com. For water quality and information contact: info(at)eternalwater.com. Phone: (925) 378-7388. BPA free product.
