For over 150 years, Mountain Valley Spring Water has been sourced from a protected spring in Arkansas' Ouachita Mountains. But what are the ingredients in Mountain Valley Spring Water that make it so special? The answer lies not in additives, but in the unique natural filtration process that enriches the water with essential minerals.

According to recent water quality reports, Mountain Valley Spring Water contains a moderate, naturally-occurring level of magnesium, typically around 7.2 mg per liter. This trace mineral, along with others, is absorbed by the water during its slow, natural filtration process deep within the earth.

In August 2025, a class-action lawsuit was filed alleging that Mountain Valley Spring Water, despite being marketed as pure, contained detectable levels of carcinogens including arsenic and uranium.
