The natural artesian springs, located in Eldorado Springs, Colorado (just outside Boulder) emanate from one of the most unique water sources in the world. This spring water originates as rain and snow just east of the Continental Divide. From there, it enters an aquifer that passes deep beneath Eldorado Springs. An immense artesian pressure forces the water up through the Lyons sandstone formation (creating a natural filtering system) where it meets the surface at the base of the beautiful Eldorado Springs Canyon. Protecting the source from all other ground waters is a two hundred foot thick layer of clay just above the sandstone that is impervious to ground water. Contributing even further to the purity of Eldorado Springs is the fact that it is surrounded by hundreds of acres of local, state and federal park land. Eldorado Natural Spring Water has a neutral pH with naturally occurring electrolytes and minerals. The springs remain 76° F year round and maintain a constant flow, assuring a consistent and true source. Our water is not chemically treated in any way. The location and unique geological environment of the source ensures continuously pure water. Eldorado Natural Spring Water has been consumed by people for generations and is recognized by many for its extraordinary quality and clean taste. read more
