Why Mountain Valley Spring Water has a pH of 7.3 – 7.8
Calcium
Around 70 mg/L of natural calcium dissolved from the surrounding limestone provides structure and lifts pH above neutral.
Magnesium
Roughly 8 mg/L magnesium contributes to buffering and the smooth mineral character.
Potassium and bicarbonate
Trace potassium plus natural bicarbonate hold pH in the 7.3–7.8 alkaline band batch after batch.
Is Mountain Valley Spring Water safe to drink?
Yes. Mountain Valley's alkalinity is geological, not engineered. It has been served at the White House and prescribed by the Mayo Clinic historically, with a 150+ year safety record.
