Our Source

Geologically speaking, Opal Springs is fed by a large aquifer, a huge underground lake. At some point eons ago, the area’s volcanic flows cooled in a way to form a vast empty chamber, creating a perfectly protected reservoir.

Massive amounts of water flowed through the fissures and gaps of the rocky topography, generating huge amounts of pressure; enough pressure to eventually break through the thick basalt walls—rushing to the surface and putting us on the map as Opal Springs.

That pressure is what feeds the springs today. We aren’t forcibly drawing water out of the ground; we aren’t pumping it out, risking siphoning the aquifer dry. In that sense, we minimize our impact on this natural process, making sure it sustains itself and that our production line is basically always on.

It’s amazing to picture the trip our water’s been on before it reaches us. The forever long of weaving, winding and flowing through hidden layers of deep volcanic basalt—the deep underground protection—all of it guarantees EartH2O’s natural purity. It’s not forced, it’s not made, it just is. Our job is ensuring it stays that way.

This is the water other waters wish they were—pure, wild and free.

• EartH2O and all surrounding communities together use less than 5% of the natural flow from Opal Springs.
• Very interesting: A U.S. Geological Services report indicates it might have been as long as 2,000 years ago that the water last saw the earth’s surface. Another answer we could give is, “Older than 1945-ish.” The water can’t be carbon-dated, but it can be measured for absence of certain markers, like the radioactive isotope tritium. Tritium is a remnant of above-ground nuclear testing that began in the mid-1940′s. Our water has no tritium in it, so we can safely say its been protected from surface contamination since before the era of above-ground nuclear testing.
