Mountain Valley

StillArkansas

Mountain Valley Spring Water is sourced from a spring near Hot Springs, Arkansas, US. The water filters into granite-based aquifers over an estimated 3,500 years. The spring was first sold commercially in 1871 by pharmacist Peter E. Greene, making it one of the oldest continuously operating spring water brands in the United States. The company has changed hands several times: from the Schlafly family (1902) through Sammons Enterprises (1987) to Clear Mountain Spring Water (2004). It is currently owned by Primo Water. Mountain Valley is bottled at source in glass and PET formats.
