A remote
recharge area.
Above the spring, the recharge area is unreachable by vehicle, construction or agriculture. Steep terrain and the geology itself keep it that way.
Fault-line-fed natural mineral water.
Fractured stone.
Along a fault in the Diablo Range, the water rises under its own pressure through serpentinized mantle rock and fractured ultramafic stone. That slow passage through stone gives the water its mineral character.
Naturally high in magnesium.
Magnesium is the signature of the source: 120 mg/L in the May 2026 analysis. Low sodium. Low calcium.

“USDA has found that over 50% of adults in the U.S.A. are getting less than their daily requirement of magnesium from food.”
