I have had premium water delivery service at my office for several years now. I got Chippewa Falls spring water. I have always liked the taste of the water until recently. So, I tested the Ph of the water, and it was a Ph of 5. That is acid.... A Ph of 7 is water, or it should be... I just cancelled my water service. Test the Ph of your water. If you are drinking acid, you are not hydrating your body. Your killing it.
