Cold-water geysers have eruptions similar to those of hot-water geysers, except that CO2-bubbles drive the eruption instead of steam from the proximity to magma. In cold-water geysers, CO2-laden water lies in a confined aquifer, in which water and CO2 are trapped by less permeable overlying strata. This water and CO2 can escape this strata only in weak regions like faults, joints, or drilled wells. A drilled borehole provides an escape for the pressurized water and CO2 to reach the surface. The magnitude and frequency of such eruptions depend on various factors such as plumbing depth, CO2 concentrations, aquifer yield etc. The column of water exerts enough pressure on the gaseous CO2 so that it remains in the water in small bubbles. When the pressure decreases due to formation of a fissure, the CO2 bubbles expand. This expansion displaces the water and causes the eruption. Cold-water geysers may look quite similar to their steam-driven counterparts; however, often CO2-laden water is more white and frothy.[1] The best known of these is probably Crystal Geyser, near Green River, Utah.[2] There are also two cold-water geysers in Germany, named Wallender Born (a.k.a. Brubbel) and Andernach Geyser (a.k.a. Namedyer Sprudel); one in Slovakia, in the village of Herľany; and one in Brazil, in the municipality of Caxambu.[3]
